Logic Analyzer Shopping
When I first got involved with electronics, I assumed that my most important tool would be an oscilloscope. I bought a Rigol DS1074Z (mini review here), a nice four channel 70 MHz scope, but I’ve rarely used it during the…

More AVR ICSP Footprints
I’m continuing to research options for alternative programming headers for AVR microcontrollers, building on the ideas I discussed earlier. For one-time programming purposes, the standard 3 x 2 pin 0.1 inch header is just… too big. I’m on the hunt…
Alternative AVR Programming Header Ideas
That ubiquitous six pin header for in-circuit programming of Atmel AVR microcontrollers – it’s the standard, but it’s not a great standard where size and cost are a concern. Can I do better? Programming most AVRs requires a six wire…
PCB Autorouting
The Apple II Daisy Chainer for Floppy Emu is done, and I’ve ordered a few PCBs made for testing. This proved to be a surprisingly challenging board to lay out and route the traces. It’s a simple two-layer board, and…
Atmel ICE Wiring Horror
The Atmel ICE programmer/debugger has its SWD connector pins reversed from the standard ARM Cortex debug connector. Arghh… why? It’s the same physical connector (5×2 0.05 inch polarized male), but the pins are rotated 180 degrees from the standard, as…
Crazy Fast PCB Manufacturing
I finished the redesign for my Apple IIc Drive Switcher PCB on Monday morning, and submitted the Gerber files to Elecrow on Monday at 11:25 am. Friday at 5:20 pm I held the finished PCBs in my hands. Only 4…
