Annnnd .... im back

My lack of posting was not due to laziness, or even too busyness .... i was simply outta town, on tour with my band actually, and after only 2 days out, my internet card dies on the lap top! HOORAY!

Tour was great, but im looking forward to getting back into things here at home, getting ready for the upcoming METROCON robot fights, and spending some time in the lab finishing up some projects.

As usual, i'll keep ya posted....

Bluetooth is go!

I've been tinkering around in the lab with the parallax EASYBT bluetooth module... got it up and running with both the BOE BOT/BS2 and the Arduino.

here is what i used...and a look at my connections

char val; // variable to receive data from the serial port
int ledpin = 13; // on-board LED
void setup() {

pinMode(ledpin, OUTPUT); // pin 13 (on-board LED) as OUTPUT
Serial.begin(9600); // start serial communication at 9600bps

}
void loop() {

if( Serial.available() ) // if data is available to read
{
val = Serial.read(); // read it and store it in 'val'
}
if( val == 'L' ) // if 'L' was received
{
digitalWrite(ledpin, LOW); // turn OFF the LED
} else {
digitalWrite(ledpin, HIGH); // otherwise turn it ON
}
delay(100); // wait 100ms for next reading


i was unable to figure out how to set the com port on the arduino ide serial terminal, so i used and external terminal program (tera term) and it worked with ease!

Synth Rig


Over the weekend we had a video shoot for our soon to be released single "The Darkest Star" ... knowing the directors style (DARKHAK) i figured i would add to his vision by bringing some synths that were interesting to look at...here's the rig i used, he was pleased. *band = Deadstar Assembly

Synth on a scope

A few minutes of watching my Roland Sh-101 on a scope.... boring, hypnotic, and exciting all at once ... be a trooper and listen to the full 3min of mind warping bleeps and bloops!

It's Officially a shop!


Once you have sparks... you've got a shop!

We spent the better part of the weekend setting up the new workspace..
we got the welder / air compressor / tools moved in, and even managed to get a workbench built.

So far so good, had a few friends come over to check out the spot and everyone seems to be getting into the "gotta make something" spirit!

robot building space


South Florida Robotics Society & The Learned Nerd are proud to announce that we finally have a work space!!!!

Our space is a 10x25 industrial warehouse bay located in pompano beach... this is as bare bones, down and dirty as it gets for robot making..it's awesome!
this weekend we will be moving in the welder, air compressor, misc power tools, and tool boxes!
we will also be setting up some work stations, tables, and shelving.

This week in the lab...















It's been a fairly productive week in the lab ...

while making "enhancements" to the 0ddr3y circuit, i happily stumbled into what some ppl call "accidental genius".....

Even though the "enhancement" to the circuit didn't turn out how i planned, it pretty much created something entirely new!

I ended up creating a very crude, but neat, pitch tracker ... i plugged the guitar in and out came a nasty lil square wave in tune with the note i played on the guitar, after playing with this for about 3 hours.. i got the idea to try a microphone, it wasnt AS cool as the guitar but it worked, it tracked my voice and created a sound in basically the same pitch. using this on my voice was a bit odd, it wasn't vocoder sounding exactly.. it was something between a vocoder and a distortion pedal... which is what 1/2 the circuit is anyway, so i guess thats about right....come to think of it, it sounded alot like plugging a mic into an old minimoog.

I wont be using this device for vocal effects, it was more just to see what it would do... BUT i will be making it into a boxed/finished version and continue to use the guitar through it ...

between this new (yet to be named) thingy and the 0ddr3y ..... you could create some interesting guitar riffs and effects that would sit nicely into some chiptune music or some 8-bit industrial!

Stay tuned, lots more to come....
