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

On a recent China order I bought five 16F72 PIC microcontrollers in SOIC for very cheap, thinking I could find some use for them. They sat in a box for a long time. Lately I've finally got somewhat caught up with work and have a little time for electronics tinkering again, so I decided to wire one u...

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...

I designed a PC board in Eagle for the Silicon Labs CP2101 USB-to-UART Serial Converter chip. These are awesome little ICs. Very simple to use. Had the boards made at DorkbotPDX, and as usual they came out pretty good.

(NOTE: This chip has been discontinued. I built a board for their newer CP210...

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...

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...
