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...
Jason at AtomSoft sent me a couple Nokia 7110 LCDs. Thanks Jason! They're nice cheap little 96x65 monochrome graphic LCD's if you can find them. In this project I build a breadboard connector for the display and write some PIC 18LF1330 code and some 18F2550 code to drive the display
I made a con...
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 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...
