futz f&ts v.i. To tinker experimentally; to change something just to see what it does

So I drew up a board for the Silicon Labs CP2102 chip and made all the improvements I wished I had done on the CP2101 board. Great little ICs. I drew the board much more compact this time and left off the unnecessary extra pads. Once again I had the boards made at DorkbotPDX and as usual they came...

So I wanted to buy a Macetech ChronoDot but they were constantly out of stock. So I drew up something similar and had some boards made. They work great.

Mine uses a CR2032 cell rather than the smaller CR1632 that the ChronoDot uses. I use the bigger cell because I get my battery holders off old...

A guy emailed me wanting to know how to write C code to do a servo slowdown device like this PICAXE one by Kevin Goom. So I started small and worked up to a full port of the PICAXE code in C. The only thing I left out is the indicator LED, but that's simple enough to add later.

I started out by...

I designed a simple PC board for the Microchip MCP2200 in Eagle and had some boards made at DorkbotPDX. They turned out really nice. This chip is a preprogrammed version of Microchip's PIC18F14K50. As well as being a good serial converter, it also has eight GPIO pins.

The board is definitely lar...

I'm posting some code here for Drizza on YouTube. Much of the original page text was lost, but I have the images and some text. So here's what I have.

I built the circuit on a dipmicro electronics PB1 proto board. Excellent little boards for building small one-off projects.

In these images I'm...
