Ok, I have complete about 90% of my PCB milling machine, about all that is left is the stepper motors, the drivers, and the tabletop. It's looking and working good. Come take a look.



Hehe, Jim... too funny, I've done the same thing, except, I don't care who's watching. Keeps them wondering..........

SUCCESS!, I have come up with a simple, accurate and CHEAP means of making an X,Y,Z stage. If you get the chance, check out the PCB/MILL project on my site: www.roboshack.com. let me know what you think..............

Ok, I have finally found some time to start on my PCB Mill / Engraving machine. I managed to get some parts and start some of the concept art. Come and take a look, and let me know what you think: www.roboshack.com

Welp, I'm not going to work on any robots for a while. I absolutely must do something about the way I build my prototype boards. I'm tired of taking hours to hand wire my proto boards, in fact its sickening. And I can't justify the cost of sending this stuff out to a PCB house. After all I'm just playing....... I attempted to use a flat bed Roland plotter to do some etching, however the resolution was terrible and I would have to make every thing 10x the size. Also, SMD is out of the question. Not to mention the little accident I had with the enchant solution. I made a few test boards using the plot / acid method, I forgot and left the plastic tub with enchant on my workbench in the garage. Several days later I returned to the garage to find all of the tools hanging on the pegboard near this tub completely RUSTED!

After a little research, I found several companies that make machines that ``Machine'' the copper off the PCB's, these machines are capable of working with SMD foot prints as well as multi layer boards. Unfortunately, they also cost any where from $6,000 to $20,000 US. Once again, since I'm just playing around, I couldn't convince my wife that I ``NEED'' said machinery. With that in mind, my next project is to build one of these PCB prototyping machines.

The concept is relatively simple, to make an X,Y,Z stage with a high speed milling spindle. At this point, the hardest part of this project is the software that reads in the Gerber files then creates the cutting paths around the traces, I'm about 70% complete with the software to perform said function. When I complete the software Ill start with the design of the XYZ stages. When I get further along Ill post the details on my web site for any one that would also like to build one of these machines!

I've got another crazy concept on how to make an eight leg walker using only 2 SERVOS!, however, I don't have time to work on it with my current project. If any one is interested, I could put together some drawings of the concept. You would have to use ``hacked'' servos for this design, however, I think it would be a lot of fun. Any ways, here's my email address if your interested: brownspotonthewall@whophlungpoo.com

Hehe, finally I get to post some information about my current project. This is a good site, however, I'm not sure I like this certification process. I feel that it might discourage people with like interests from posting their projects, thoughts and ideas, or in fact prevent them from doing so.

Thank you for the certification theymightberudy.........:)
