As part of the newest generation of BOBs boards, two buttons, and possibly (if I have enough pins left over) a few DIP switches. As a result, there has to be code to use these buttons and put them to work. This is where my new development board comes in. Continue reading Development
Some of the regular visitors may have noticed that the site has changed a little bit. I finally got time a few weeks ago to sit down and totally rewrite the theme. Three hours in total, at 2am I was posting the theme live.
I have just recently started to build my own Eagle parts library as I move to SMD parts, and parts that are not as common as resistors for footprints.
You can get the library here, along with an updated/fixed version of the Sparkfun library that has the correct pin-out for the Attiny45-SOIC-8.
My first etching tutorial was both my first tutorial, and also a tutorial in a subject that was fairly new to me at the time. In other words, it sucked. Big time.
This time I’m going to try to do it right, and have photos to prove it, So lets get started. Today I’m going to teach you, or make a feeble attempt at teaching, how to etch a board, from start to finish.
A few items of update. First off, TI has launched a new product, the MSP430 Launchpad.

The Launchpad is a $4.30 with free shipping dev board for TI’s MSP430 chip family. On the board there is USB which supplies power, and acts as the debugging emulator and the programmer for the chip, and then a nice 20 pin DIP socket for the MSP430 chips. The board breaks out all of the pins for the chip, and also has a spot for an external crystal. After a very frustrating, and long cursing at TI’s servers spurt, which lasted a good day as the Launchpad was so popular I finally got around to placing my order, however the backorder for the Board looks like I will have it around the end of July, start of August sadly. Hopefully I can find, and build a dev environment for the MSP430 on linux, seeing as there is a GCC port for it already all that is left is integrating it with Code::Blocks, and finding a way to upload the code to the MSP430.
Other goodies that I have received include Continue reading Even more updates
Half the time, something works, the other half of the time it doesn’t, and the other half of the time, it just goes up in smoke. As such was the case with my V1.5 Rev. 1 quad motor controller. Continue reading BOB update
Update: Having moved servers, and stopped using my previous image gallery plugin, photos for this post are not showing up. Over the next few weeks, I will be working on fixing this, but please bare with me. Feb 11, 2012
Having completed etching my Quad Low-side motor controller board, I needed to drill out the holes, the only problem: I don’t have a drill press, and the nearest readily available one is at my grandparents house two towns away.
So I finally got around to fixing a few things, and cleaning the board up, here is BOB’s newest working version of his motor controller board. Continue reading Revision 2 of Quad Low-side “Taco”
So I finally got around to getting a board designed for Generation 3 electronics, but like everything else, being the first prototype board there were some things left out and other mistakes.

A few people have asked how I do the curvy traces in eagle so I though I would do a little 5 sec how to, simply, when routing, use the three curvy lines for the trace style at the top of the eagle window:
