I have an odd obsession with small, relatively cheap hardware development boards. Over the last few years, I’ve acquired a bunch of them, from Arduino to Raspberry Pi to BeagleBone Black. I thought it might be nice to just do a short video showing what I have around. So I did. Here’s a little 25 […]

In my previous article pondering sensors for my garden, I shamefully neglected a viable and interesting choice, the JeeNode

I have written one or two programs in assembler for these chips, but I prefer to work with avr-gcc whenever possible. What’s amazing is that you actually can use a sophisticated C compiler to generate code for such a […]

This is a very cute hack that does something which I thought was impossible: an implementation of an FM transmitter that has exactly two components: a battery and an ATtiny45 microcontroller. It’s brilliantly obtuse and cool: Sprites mods – AVR-based FM-transmitter – Intro, theory The basic idea is to trick the internal oscillator of the […]
