Added a writeup of my favorite DIY in-system programmers (ISPs) and added in a link to PCB designs. Build your own!
Coming Soon: Make Magazine Website Skill Builder on using an Arduino as an in-system programmer (ISP) for AVR chips.
Coming Soon: Make Magazine Skill Builder on using the AVR hardware serial peripheral. Code is up now here, on Github. The project is the most I could do with the least code — your computer lights up a button on the AVR, which then loads a webpage when you press a button. There’s a "secret" Easter-Egg webpage waiting for you once you’ve built it.
I gave a webinar for O’Reilly on Making USB Devices with AVR and the V-USB library. I covered both making a simple scroll wheel (an example of an human-interface device class) and a custom device that sends arbitrary messages back and forth over USB, with host code, that points a servo motor depending on the weather forecast. Check it out. Code and more details are here, on Github.
I’ve decided on a final design for the ATMega-series V-USB prototyping spiders. Check it out! When I make this into a kit, I may switch up to through-hole parts. What do you think?
Lately, I’ve been using my 3D printer for more than 3D printing. Check out Your 3-D Printer is the World’s Most Expensive Etching Tray Agitator, now with dramatic video!
A collection of my favorite little (DIY) tools for prototyping with AVR microcontrollers: the AVR Pro-Pack
Added support pages for the brand-new Maker Media title "Make: AVR Programming".
