About
Hello, my name is Jeff Keyzer. This is my blog.
A few things about me:
- I’m an Electrical Engineer. I studied Circuits and Systems at the University of California, San Diego (MSEE ’02).
- When I’m not traveling the world, I spend most of my time in
San FranciscoAustin, Texas. - I have over eight years experience in radio frequency integrated circuit (RFIC) design. Most of my experience is in designing power amplifier chips and antenna switches for wireless LAN and cellular devices.
- In 2008, I started doing freelance design work in embedded systems development, PCB design, and electronics prototyping. (The really fun stuff!)
- I’m an occasional guest-host of The Amp Hour, “an off-the-cuff radio show and podcast for electronics enthusiasts and professionals.”
- I’m currently co-writing a book (with Mitch Altman of TV-B-Gone fame) about making fun projects with AVR microcontrollers, to be published by No Starch Press. One notable offshoot of this project is the Soldering is Easy comic book that I created with Mitch Altman and Andie Nordgren.
I blog primarily about electronics and embedded systems. Expect to see posts about microcontrollers (mostly PIC and AVR), Arduino, embedded Linux, electronic circuits, DIY projects, and other related stuff. Most of the projects featured here were born in my lab, but occasionally I will feature projects from friends of mine as well.
I also sell a few things that I designed, including a very popular Open Source Geiger Counter kit.
Aside from my obsession with electronics, I enjoy working on old cars, machining, welding, fabricating, and generally building stuff.
