Well, I took the plunge and posted my LED display module on ebay.

24 May 2006 (updated 24 May 2006 at 08:32 UTC) »

Well, I've been making RBSs still and selling them on ebay. I've tried painting them, but I'm not sure I like the way they come out. I started work on another granfather clock. This is the one that the computer I spoke of before will be added to. I'm not really happy with the elevator system, but I guess it's ok. It sort of warbles a little. The clock face back I made from a thin piece of clear plastic sprayed with frost paint. I sort of messed it up and so I decided to scratch it up, and the texture came out cooler than if it were plain! I really like it! I made the clock hands a nice metalic blue against the white frost backface, it looks kinda cool.

I had a guy in England email me to comission 3 RBSs. I gave him a quote and haven't heard back from him. Probably because the shipping would be $50 a box for 3 boxes!!! Yikes it's expensive to ship overseas.

While working on the Grandfather clock and messing with the analog hands, I thought it would be better to make a digital display for the clock instead. So I looked into making a dot matrix type LED display. I figured out I could fire up 6 5x7 led blocks with one 16f877a pic chip! So I made a PC board and hobbled together some software based on my scheduler code, and incorporated the i2c stuff and came up with a 6 character LED module! It looks pretty cool. You can see it here. (you'll also get to hear some VBS background music on the video that my daughters and I made a few years ago for fun!) The code has one process that updates the display constantly, one process that parses incoming data from a buffer, an i2c interrupt that fills a buffer, and various functions for doing all the commands that get parsed, two fonts one regular and one narrow, and not to mention all the scheduler code stuff. I managed to get it all hobbled together fairly quickly (in a few days?) since I already had a lot of the things made for other projects, I just had to gather them and dump them all into this soup mix. I'm fairly happy that I got it initially working so quickly. So I got to thinking, I went through all this work to make myself an LED module for my RBSs, I wonder if anyone might want to buy one also. So I'll probably test it some more and then put it on ebay to see if it will sell. I haven't seen anything like it around, so it may be something someone might want. I'll probably try to list them around $50 and see if it goes. If not, I'll just use it for an RBS so no biggie if it doesn't sell. For the board, I made it fairly versitile where I could add 9600 baud serial to it later since many people would rather have one with rs232 than i2c. So, there's a header block for the serial, but the programming for it's not done yet. Also, I've added other things, such as address selection, and such, but that's not programmed either. I made the i2c incoming data protocol as if it were receiving serial commands so it'll be easy to adapt the parsing routines to either i2c or serial. It'll just take the text out of the same buffer and parse it. Anyway, it's good and bright and very slick. I'm very happy with it. I'll probably try to make it more fool proof and put a watchdog timer and such in it to try to make it as bulletproof as possible. Anyway, I've been having fun playing with it.

Hey, we might have a new dog! The dog was hanging around our garage and it looked pretty hungry. It was very friendly so when I reached down to pet it, I could feel the poor things ribs really bad. Like anarexic! So I got a couple of bowls out for it, one with water, and another with some old oatmeal cookies we had and the dog just wolfed them down. Well, me and my daughters sat outside for a while and played with it. Of course by then, we tried to get inside, but the dog kept trying to go with us. Finally, we sat out a box with one side cut out and put a towel in it for a bed and it's crazy, but the dog went right in and laid down. So the next morning, we came out, and there was the dog in its bed and happy to see us. Like we couldn't get rid of it cause it found someone who would feed it. So we sort of adopted it or it adopted us. Well, my daughters have been begging for a puppy forever but my wife was the hard one to convince. We decided to fence off the kitchen and keep it there. I mean, this puppy, is really something. It rarely ever barks. It waits to go outside every morning before pooping and tinkling. When we go outside, it rarely goes beyond 20 feet away and is usually so close you're tripping over it. You call it to come back inside, and it does farily easily. When inside, it plays with you when you're around, and is fairly peaceful when you're not. It's like this thing is totally trained to be good. I'm totally shocked. It's really unbelievable. Well, we went to the neighbors around and talked to them about it, but no one knows anything about it. So, we've had it about a week so I guess it's ours now. We named her Scamper Germany Brown. You can see a picture of her here.

At church, we've started having an electric guitar and a bass guitar on stage with the piano and organ. That's really a big step for our church. So far none of the "keen-agers" have said anything negative and for the most part all I've heard is good things. It's been a lot of work. I've been helping them learn the songs for a couple of hours on Monday, and then we meet an hour early on Sunday to go through the songs again. On Sundays, we've had some funny technical things. The first sunday, the sound guy thought there was something wrong with the sound so he brought the guitars down to almost zero volume. Then the next sunday he wasn't there, we left the sound up and it sounded great. The next sunday he wasn't there either, but our youth minister went upstairs and inadvertantly turned them down. I just don't get it. Everyone seems to love it, but we can't get the sound system to let them play!

Since I'm the music minister, I'm sort of in charge of the sound system. Well, I've been wanting to get a new wireless lapel mic for our preacher because our current one is old, it's the old FM type, and it makes rudes noises every once in a while. The new one however, which is UHF and has many newer features, costs $399. So we've been sort of begging for money from the congregation for a couple of years now and we have a "microphone fund" so if anyone wants to designate a donation, we're ready to accept it! :-) Well, anyway, some wonderful soul at church donated like $600 to that fund, and in business meeting it was approved to go ahead and purchase it! Wow, that was cool! So now, I just have to go get it! I know it sounds silly, but I'm really glad and happy about that! It's like a ray of sunshine!

Well I'm finally finished making the 30 RBSs! Hopefully that will free up a little of my precious time to do some other things I've been needing to do that have been stacking up.

My little RBS business has helped keep me going for a while now. I guess you could say I finally have a real business now! It barely sustains us, but I've been out of a job for about a year now other than making RBSs and other odd jobs, so I guess it's sort of going. It really needs to make a lot more money before I really will feel comfortable with calling it my day job, but at least it's keeping our mouths feed for now.

When I haven't been making RBSs, I've been working on my computerized RBS. The computer part has been coming along nicely if a little bit slower than I've wanted. I'm hoping to get all of the electronics part finished soon.

I've got about all of the bugs out of the scheduler so that it works fairly well. It can run several processes (10) all at the same time. I have a process servicing the LED, LCD, RTC, Keyboard, Sensors, Buzzers, RF Commander, Elevator Motor, Clock Hand Stepper Motors, Lights, etc. Some processes do dual duty like the keyboard and rf commander are both handled in one process.

I made the 16x2 LCD display big characters by making 8 graphic characters that can be used 4 or 6 at a time per character. They look fairly good. I can display the time in big characters so you can see them far away. When the menu isn't used for a while, it switches to displaying the time.

I got the I2C thing figured out. I had to bit bang it since the pic16F877a eval board I was using didn't wire them right. But no biggie, I sort of wanted to know the ins and outs of it anyway. So I got the RTC clock giving me the time, the EEprom storing preference data, and above all, I've made a pic16f84a i2c port expander to drive the stepper motors for the clock hands. Yep, that's right I bit banged and i2c slave chip too that handles 2 stepper motors and a few LEDs with PWM for dimming them. I'm really liking i2c for distributed computing. I'm thinking it's so nice that I may make some more little i2c modules and such. So basically, right now, I have a main computer that handles the menus and such, and a second computer that handles the steppers and leds and such, and rtc and eeprom all on the same i2c bus (well actually, eeprom is on a separate i2c bus but I'll probably change that). Anyway, I like that i2c bus way of doing things!

I've had a few problems with the DC motor since it likes to reset the processor when I turn it on. I added a few capacitors and it seems to have gone away.

I also had problems with that 1F cap. It poped! I had another and it worked a while and popped too. I guess they're very delicate. I don't know why they popped. I replaced them with 1000uf caps. For the clock, I wired a 100uf cap directly to it's vdd with a diode so when power goes away the 100uf cap powers just it and doesn't power everything else. That keeps the EEprom going for about a minute. That should be long enough for most brief power failures. I thought about putting a bigger cap on it but I added it to the bottom side of the board so it wouldn't look so nasty hacked onto the top so I used the small 100uf cap.

I replaced the non-working buzzer out for a little speaker from an earbud headphone. I made it do low, med, and high pitched with long and short beeps. It's not too loud and it's kind of cute. I don't know if it would cause problems with anything electrically, but it seems to be a good cheap solution.

For the clock hands, I found out the steppers I bought were 24 step steppers. That was a little disappointing because I thought they were 200 step steppers. 24 steps alone is really not good for a clock. 60 or more steps would be ideal. So I switched to using half step logic. That got me 48 steps per rev so that would be ok for the hour hand. For the minute hand I decided to make gears out of wire. Wire gears would keep the look for a wire RBS. I'd have a 12 tooth pinion gear and a 15 tooth drive gear for a 1:1.25 ratio or 60 steps. That just barely is good enough for the minute hand. Really I would have liked double that but making a bigger gear out of wire is harder to make. I have the two opto sensors working for the clock hands so it can tell when the motors are at top dead center then it can position the hands for the rest of the time by steps alone.

Just about everything is working on the electronics. I have some more software I want to add and I still have a whole bank (2k) that I haven't used used and some more here and there.

I'm really looking forward to seeing this clock being built and finished. I have a few other people that seem interested in seeing it working too. Of course, my wife just thinks I'm nuts. I've pretty much learned to ignore her. She just thinks things are cool when they bring in money.

I've downloaded express pcb and sch and played around with it a little. I'm hoping if this electronic RBS thing works out that I may start making a few custom boards so that I don't have to solder everything point to point and kill lots of my time and effort. I think I want to make everything modular and use a standard i2c header on everything with power, ground, SCL, SDA, and a few other pins. Something where I could reuse a module for another project if I wanted. I'm sort of into the electronics stuff again for now since I've just built a few things and hacked some electronics stuff lately.

I got my PIC16F877a Eval board in the mail from Hong Kong. It had absolutely no documentation other than what was on the web page (which was very sparse)! Wow! Anyway, I had already scoured the pics on ebay to figure out pinouts and such. I had written a test program before I received the board. I burned the program into the pic, and with some tweaking actually got it up and running! I'm fairly happy with it. I have a 16x2 LCD with backlight, a 4 digit LED display, 4x4 keypad, Real Time Clock, EEprom, buzzer, serial, and other junk. There's probably better computer boards out there, but this has keypad, display, and i/o for $40. I'm pretty happy with it. I don't think I could have bought all the parts and assembled for less! Saved me a lot of work that I was planning on doing. I'm glad I found it.

The LCD and the LED displays share the same PORTB. That's really weird because they're always conflicting with each other. You send a LCD command and it shows up on the LED display. You send a LED output and it messes with the LCD display. What I figured out was that if you set the LED the way you want, then before turning it off setup a LCD xy command then click the E line, the LED is happy and the LCD is happy. So, basically they're still conflicting with each other, you just can't tell it. So the LED runs fast enough with persistence of vision you don't see the little LCD command, and the LCD gets a xy cursor command, which you don't see either.

I also got a wireless 4 button remote from the same guy. Again, absolutely no docs except what was on the web page. The receiver board was simple so I went ahead and hooked it up to the 877a board. I made it so that when you press button A on the remote it displays A on the keyboard. Also for keys B, C, and D. Yea, it works! So now when I build the RBS, I can have it remote controlled to drop a ball or adjust the time or lights, etc. by remote! Cool.

I arranged the keypad buttons on the eval board be like so:


      +-----+-----+-----+-----+
      |  1  |  2  |  3  |  ^  |
      +-----+-----+-----+-----+
      |  4  |  5  |  6  | esc |
      +-----+-----+-----+-----+
      |  7  |  8  |  9  |  v  |
      +-----+-----+-----+-----+
      |  <  |  0  |  >  |enter|
      +-----+-----+-----+-----+

So I have numbers, arrows, escape and enter! I'm very happy with that. I need to figure out a good way to label the buttons (stickers or something). The 877a eval kit comes with a bread board! I used it to tie the keys input to ground thru 1k resistors so that they would work right.

So far, I have a simple menu where I can scroll up and down. I can go into a menu item with enter and I can back out of a menu item with esc. Right now it just displays a simple menu: set time, ball drop pref, about. The about menu item is all that works right now. If you press it, it will display "Grandfather clock", "See www.swirlingbrain.com", etc. plus up and down graphics chars and and "ESC" graphic char to let you know you can use the up and down arrows and esc to hop out. It's the best user friendly I could muster.

I have several background processes going: One that updates the LED display with the time (although it's not read from the real time clock chip yet), one that scans the keyboard and puts a key to a key buffer and has debounce, one that scans the rf 4 button remote, one that works the elevator motor (don't have the motor hooked up yet), one that works the stepper clock hand motors (although they're not hooked up yet), one that reads the RTC every so often and updates the clock (not done yet), and a few other misc processes for a total of 9 out of a possible 10 processes going on my scheduler code! I'm so glad it works!

So far of the 4 banks of 2k (8k total) I've used 1/2 of the first bank, and 1/4 of the other 3 banks. So I still have plenty of code space left. So the total code is about 2.5k right now out of 8k that I have or about 31% or so. Really I have a lot of code in there already so I'm pretty sure I'll have enough code space to do all I want to do and more!

Really, I'm thinking this setup might be really nice for a robot main board. I could hook a RF serial connection to the board's serial port and control the robot through a PC and I could use the wireless remote for sending simple commands like start, stop, and two functions. Interesting.

Well, Bethany's been in the hospital for about a week now. Her PFTs had dropped to 67% and they wanted to get them up. So she's getting a tune up! She's doing Ventolin, Tobi (aerosol tobramyicin), Dnase, Intraveneous Antibiotic (probably Tobramyicin). Basically, all the stuff we do at home in a more concentrated form plus all the intraveneous stuff. Teresa's taken off of work to stay at the hospital with her. That's killing us! Any extra I made with the ball trails this week is getting eaten up by Teresa staying off of work. :-( The latest is that Bethany dropped below 65% so what we thought would be news of her leaving the hospital today is met with news that she's worse than when she came in! Ugg. So now we don't know when she's going to get out. The doc is so funny, he said, "She should be out of here by Christmas!" Yeah, like that's so funny! We got two for the price of one: A doctor and a comedian! Woohoo! Bethany's been living up. She gets to eat all she wants - they just bring it to her in bed! She's been getting presents and candy left and right! People call her and talk to her for long periods of time. She gets all the sympathy she has ever desired! All that and she doesn't have to go to school! She did spend her spring break at the hospital, but at least she didn't miss that week of school.

Me, we'll I'm wasting time when I should be making RBSs doing PIC16F877A programming. Why 16F877a? Well I bought a couple of 877a eval boards that I want to use as the brain for a granfather clock RBS. The boards have everything I want like a RTClock, Display, keypad, & pic cpu. The boards even have a ZIF socket for the PIC chip for "crash & burn" type development! Or you can use the serial port on it with the pic bootloader preprogrammed into it. It needs to have more I/O for all the junk I want to add on it especially a couple of steppers to drive the clock hands. I figured I would just use an 16F84 via some comm line (probably i2c) to drive a couple of steppers. I want to use i2c because it's already being used by the clock chip and the eeprom on the eval board. I figure I can just tap into the lines so I don't have to use any more i/o for comm to another chip. Also, I wanted to get my hands dirty on i2c to see how I like it. The 877 has i2c onboard. the F84 it'll have to be a software emulation of it but I think it will fly.

So, I dusted off my scheduler code and got it tested in the debugger. Found a few bugs and squashed them. Upped the number of tasks to 10 and moved the schedular and my interrupt service routine variables up into bank 3. Dealing with the banking issues RP0 & RP1. Also had to do it for IPR since I was using FSR and INDF variables. Got that all working again. So now my code and variables have room in the other banks.

One thing I ran into with the 16f877a was the PCL (Program Counter) being only 8 bits. I don't remember it being that bad on the 16F84 but perhaps I just didn't pay attention. So what happens is if you want to do a table lookup, you have to set this other register called PCLATH with the high byte of whatever label you want to jump to then modify your PCL to do the table jump. So the PCLATH is the HIGH byte, the PCL is the LOW byte, and viola, you have a long relative jump where you can programmatically go anywhere you want! So the 16f877 has 8k of program memory in four 2k pages. That means that eventually your goto and call functions won't work either as they only address 2k? of code space. So again, you have to load some of the bits of the PCLATH first with the high byte of your label address to do a long jump or a long call. Since it starts getting confusing as to when you should or shouldn't load the PCLATH, it gets to where you just do it all the time now to make sure you aren't missing something. Or, perhaps your program expands and if you didn't do one before your program just mysteriously quits working, so you better do it now or you'll mess up later. It would be nice if there was some kind of macro that would figure it out but I guess that would be confusing too. So, there iS Assembler page pseudo thingys you can insert into your code. I haven't researched them enough yet but for now I haven't used them. Anyway, that's the weirdness I found with the 16f877. It's not a show stopper, but I sure don't think PIC programming is as easy anymore as I used to. I guess other CPUs have code pages too. I just thought that was a thing of the past. Really makes you appreciate 16 bit processors as opposed to 8bit. With 8 bit processors you're always dealing with math issues and addressing issues. Just move up to 16 bit and they all go away. Well some of them do anyway. PICs should be 16 bit I tell ya! Imagine the poor souls who had to deal with 4 bit processors way back when! Yikes!

I tried to look into using some freeware version of PIC C language. The problem I ran into was they would have support for rs232 but not for i2c. I need i2c for my real time clock, eeprom, and stepper controller chip (that I have yet to make). There was some other things that were missing or seemed to be a problem, like a huge RTOS which would suck away a lot of my resources, limited freeware stuff (like the freeware version is limited to 2k of your 8k available and the pro version is like $250 or more), there were other things I ran into also, which at the moment are not coming to mind but ended up being a show stopper for programming in C on a pic. :-( I was really wanting to do that eventually. I guess it all takes lots of money which I'm not willing to let go of right now.

Also, I ran into problems with the Linker. I have a bunch of relocatable "code" and "udata" pages. For some reason I couldn't get the linker to accept them and just pack them in right. Like I haven't broken 2k yet so you'd think it would just stuff them all in the first page. I got the sample template for the 877a and added my files to it. I just about thought I had it working but I kept getting some weird error when the linker finished. So my remedy was just to put all the code and data back into one big file and assemble it. Like no real linking happens so it just builds the hex file. Stupid linker! What a big waste of time. There again, linkers should be easier! No telling how many times, even on really big projects, the CMT guys always had trouble with linking stuff the right way. Like building the perfect automatic linker is a field that's ripe for picking. Yeah, yeah, I know it's more complex than that but really, why does it have to be so complex? Like standardize linker coding into some easy "basic" like linker language so you don't have to learn a zillion linker weird structure info languages. I guess it's from severe lack of being or even wanting to be a Config Managment guy. I mean is it so much to ask that I should just be able to write a program, and the thing just automatically builds the right way without me having to tell it a bunch of junk it should already know of should be able to figure out on its own?

I'm about 20% done with the RBSs that I've been contracted to do. I'm a little behind work on them. Partly because of having to travel down to Children's Medical center so much this last week and partly because I get distracted easily. I'll build on a sculpture for a while and it'll get hot. So I'll walk away from it to let it cool. I get busy doing something else, then it's hard to get back to working on the sculpture.

I believe my life is a type of roller coaster. I know that's so profound. I'll go though periods of being bored. So I'll find things to do and start filling up the bordom. Just about the time I get happy with the fact that I'm not board and I've occupied my time with something, that's when a bunch of things will arrive that I "have" to do. SO, all the things I want to do which I've spent time and money gearing up for, have to be put on the back burner to do the things I have to do. Part of me tries to keep doing the things I want even though I really don't have time for them any more. So then the things I want get dropped altogher and some of them get lost (or rather what I like to say, "got cleaned out of existance" - a term borrowed from Eric Yundt). So then the "have-tos" start going away, and my want stuff disappeared, I get bored again and the cycle repeats.

Looks like the VEX Robotic system may be on 1/2 price sale at some Radio Shacks! They're usually $300 for the starter kit and now they're $150! Woo hoo! Get yours today!

Well, I got another beep on my cell phone this morning. I got an order for about 15 or so more RBSs from the same guy that bought all my inventory yesterday! It's for $2335! He paid $1000 now and he'll pay the rest when I'm done! Very cool!

Last night I bought the stuff to make a computerized clock RBS. I found a nice pic computer board for $40 that has a 40 pin 16f877a pic, 2 line LCD display, 4 digit LED display, Real Time clock, extra 256 btyes 8 pin dip eeprom, buttons, buzzer, 3 analog, and several more I/O for my motors and sensors. However, it may be about a month before I can get to it since I need to make the RBSs that were ordered!

Well, I took the plunge and opened my swirling brain store on ebay. They give you 30 days free so I thought I'd try it for 30 days and if it didn't work out, I'd just close it before the free trial ran out. Also, there's some sort of contest where if you make the best store you get free tickets to Las Vegas. I know that's a long shot, and I don't buy lottery tickets because I know they're a sure thing for losing. But, hey, if I'm openeing the store anyway, might as well enter the contest too. Like who knows! So anyway, I got all my inventory: The Grandfather Clock, the new 4' ball trail, some little ball trails and such and listed them on ebay using the inventory format. The cool thing about the inventory format is that it costs only like 3 cents to list an item for 30 days. The only catch is that they charge you a hefty fee at the end. Another catch is customers can bid, they can only do buy-it-now, but they can do offers, which is almost as good as bidding, right? So, I got my store created and listed some of the items. After about 3 days I was already discouraged because there was a lot less page hits and watchers than regular items. Then this morning my phone kept beeping. I have some of my ebay messages forwarded to my cell phone. I got up and looked at it and saw, "instant payment received!" Woo hoo. So I ran to my computer and it was for $2425! That's the biggest RBS sell I've ever had! The guy owns a company in Korea and he's emailed me a few times but he never did buy anything until now! Now paypal took $94 in fees. I cringe to see what ebay will take in fees but I think it's going to be like 5% which would be another $121 or so. But hey, that would still be like $2200 I didn't have before! That's cool! So anyway I called my wife at work and I called my dad and you know today I'm going to be all happy and stuff. :-) Praise the Lord!

We've been overrun with fruit flies. Teresa bought some tangerines and I guess the fruit flies came in with them. We put up that sticky fly paper and we tried to get rid of anything we thought they would eat. We did find some old ripe bananas that they found. Yuk. So Harbor Frieght had a sale on handheld bug zappers for $2.50 each! So I bought two! Two D cell batteries power this thing and it has big bold red stickers that say don't touch the grid when you push the button and not for children nonsense! It's like I have this urge to stick my tounge to it (not really). Anyway, you pass this thing over a fruit fly, and there's this BIG spark and a loud "crack!" Sometimes they sizzle, but most times it's a cool loud lightning pop! Wow, this thing is like major fun! Ok, yeah, I get my jollies from weird things! So at first I was catching fruit flies left and right, pop, pop, pop, pop, and so was my wife! We were swinging these things all over the kitchen and really getting after it! Wow, what addictive fun! Now, we still have a couple of fruit flies, but this electric fly swatter thing has really done the trick! It's like, let's go buy some more tangerines so we can have some more electric fun!

Released the RoboMenu widget today! Woohoo!

Here's some video of my latest Rolling Ball Sculpture.

It's currently for sale on ebay.

Our pastor quit. It was either that or get voted out. He saw it coming. I hated to see the guy go but he had a few problems with people and became ineffective. Anyway, since he left, we've had a little revival of sorts. We started up our visitation program again, and started a few programs such as youth choir and men's bible study and a few other things. I don't know why we couldn't have done it before, but now we are so I guess the change is a good thing. For now we are not going to persue searching for a new pastor. A guy who used to be a preacher until his wife left him is preaching Sunday mornings for now. He's been doing an excellent job. I have a lot of optimism for our church this year - I think things will work out for the best. It's too bad church has to be such a soap opera all the time, tho.

Teresa's mom gave us her dad's GMC Sonoma pickup since her dad died. It has 192k miles and the paint job was totally washed out. I talked with my dad, and we decided to repaint it. He wanted to repaint his truck too. So we went on ebay and found a company that sold the paint, reducer, clearcoat, paint suit, and masking tape fairly cheap. It was a little more than $100 per car for everything. Well, I spend a few weeks sanding and bondo-ing. My dad did too with this pickup. We painted mine first. Mine came out with a bit of an orange peel texture to it rather than the smooth finish we wanted. My dad waited about a week and tried to read up on the internet about how to do it. He then tried but his didn't do much better than mine. I got some 400 grit, 800 grit, 1000 grit, rubbing compound and other compound. I sanded and rubbed on the hood and finally got a finish that was smooth as a mirror. It takes a long time, but I'm confident I can make the finish look good. Too bad we couldn't figure out how to spray it right so that we didn't have to waste a lot of time and effort sanding and rubbing. But at least it should look nice when we are finished.

At church we had an old concrete sign that needed to be removed. I talked to my dad about it and he recommended renting a jack hammer to bust it up and then haul it to the dump. The youth minister and myself started around 9am and took turns with the jack hammer. We then loaded the concrete into the back of my little GMC sonoma. It totally filled the bed. I guess a small concrete sign when it's busted up grows about 2 or 3 times it's size when bused up! The pickup was very weighted down. Driving was like looking at the sky! I was really worried that we would pop a tire and then that would be a bummer to change as we'd probably have to unload all the concrete to change it. Anyway, the tires didn't pop. We didn't finish until about 3pm. It really took a lot longer that I'd thought and we were really sore after it was over.

Got my tax money back. We actually got most of our money back since I've been out of a job for the most part. I estimate we're good until about June at this point. I really don't know how to explain how we've managed to survive a year without me having a job other than to chalk it up to help from family and friends and to just praise God for them.

We've had a few appliances that have broken down. Our stove and our oven no longer works. I bought a little $10 electric range from walmart so we could fry some hamburger meat now and then. Also, our washer now overflows. Without having any money, it's been a little bit of a bummer. We've made due with a microwave the electric range and a george forman grill. Also, our food stamps run out this week. I'm hoping they will reinstate it but we'll see. I'm sure there will be a lapse as the food stamps people work as fast as mollasas. When I went to the doc, I mentioned that I didn't have a job and they let me have a bottle of insulin for free (yes, I have diabetes). That was like $80 bottle! That was cool! However, the doc bill was over $200 so it's not like I really made out like a bandit or anything. My credit cards are getting close to being maxed out. I noticed that I've started getting junk mail that says stuff like "you can still buy a car with your bad credit" kind of stuff. I haven't missed any payments yet and I still have some credit but it's really getting to a point where at some point I'll cross some threshold that I won't be able to recover from if I haven't already crossed it.

I've pretty much given up on a computer job. I don't get any headhunter calls, and any emails I get ask questions like, "what have you done since '01." Which pretty much the answer is "nothing" so I'm in a type of catch 22. Like you can't get recent experience if you aren't working, and they won't hire you without recent experience. Like I can have 15 years of experence but if it hasn't been in the last year then it's no good. I'm sure not having a bachelors doesn't help either. There was a time way back when, when I thought I'd always be able to get a computer job with my experience that I've had. So, now it's just a matter of finding some low life job and trying to supplement it with all my odd jobs and ball trail sales.

I got to do a little computer work for Roger. It was a Robots.net konfabulator widget for robots.net. Roger and I both have it running on our desktop. It's fun watching the RSS from robots.net show up on my desktop. I'd release it to the world, but Steve mentioned that he's needing to make some changes and such first that he's been wanting to make that would break the widget. So I'm waiting until the changes are made and then we'll release it so everyone can enjoy it. Anyway, it was kind of fun actually doing a little programming again. Yeah, ok, I did some PIC assembly recently for one of my ball trails, but this was like real programming that the world might get to use.

Sold some more ball trails on ebay! I'm not getting what I really want for them, but at least it's some income and I'm not losing money on them. I had one dentist that wanted to buy the grandfather clock. He won't buy it until he comes back from vacation. I'm not sure if I'd rather be led on like that or not. A few days ago, I had a Korean guy express interest in buying about $3000 to $5000 worth of ball trails. Haven't heard back from him either. Anyway, the thought of possibly selling that much at one time was exciting. I've just about given up on him by now - I guess I'm just impatient. The Korean guy also wants the grandfather clock and is willing to pay more for it. There again, I'd sell it to him if he'll just "show me the money!" :-) I can always make another clock for the dentist guy if I need to sell two clocks. It's funny that I had no buyers and now I have two on the clock, yet neither two will "show me the money!"

I got another ROBOT magazine today. I haven't looked at it yet, but I'm excited!

For our cell phones, we had virgin mobile prepaid. It's a really great deal if you don't do much talking and it's only for emergancies kind of thing. Anyway, we found another company called STI Mobile that had a deal where you get the phone free after rebate if you buy a $50 minute card. The minutes are 12 cents on weekdays and 10 cents nights and weekends. So we got two. About a week later, we noticed that the balance was going down quicker than we thought it should. Turns out that after we had the phones a few days, they changed the rates on us where they add a 10 cents a day charge. Also, they added a 19 cents a day charge for the internet which we didn't ask for but they put on automatically which you start. So I emailed them to remove the internet so that part is fixed. So, when I researched this rate change, I found on a Fat Wallet forum that STI Mobile has started doing some questionable things like changing the rate deal and also changing the rebate deal. They are saying now that to get the rebate you have to use over 100 minutes a month for three months to qualify for the rebate and then you'll get the rebate 4 to 6 weeks after the the 3 months. My heart just dropped. Some of the speculations is that STI mobile will probably be going out of business and that this was a last ditch effort to try to stay in business. So the great deal has turned into a really bad deal. Oh well, it probably still meets or beats what we were paying for on Virgin Mobile so I probably shouldn't complain too much, but we were trying to save money anywhere we could and it just didn't work out as we'd hoped. Anyway, we like the new phones. They are color flip phones and seems to have much more pixels, contrast, and better sound than the old b/w virgin mobile phones. I gave my old virgin mobile phone to my daughter Bethany because it still had a few bucks work of minutes left on it. She felt like she was in heaven. She was showing off her phone to all her friends and text messaging everyone and making quick calls to a few of her friends. It was fun seeing her so excited if only briefly. :-/

Rental movies I've watched recently:

Serenity. I'd give it 3 out of 5. It had a decent plot and was a space sci-fi. No real swirling brain moments, but reasonably entertaining. My wife walked out of the living room, she didn't like it. It's definately a guy flick.

Enemy of the State. I'd give it 4 out of 5. It had a plot that kept your mind active. It had some swirling brain stuff to it. Very entertaining. Definately a guy flick.

Forgotten. I'd give it 3 out of 5. It had a weird alien plot but interesting. A few swirling brain moments. I enjoyed it but I'm not sure everyone would.

Movies I skipped through or stopped watching because either they were too boring or stupid: Lady killers, Iron Thunder, a few others I can't rememer.
