So at the moment, I’m working out how I can keep track of 16 RGB LEDs with only the tiny 32 bytes of RAM in the ATtiny10 microcontroller to play with. The RGB LEDs each read three bytes of serial data; one byte for red, one byte for green and … “Color Hacking”

My new electronics / programming virtual machine. I tried a number of desktop environments for Ubuntu including Unity, Gnome, Cinnamon, Xfce and LXDE. The manner in which Unity and Gnome (the latter being almost unusable without extensive customisation) arrange their menu systems is very annoying. Xfce felt just a little … “Electronics / Coding VM”

This Altronics FM Microphone kit I did get to work unlike the Jaycar kit. The main difference is the inductor which is preformed as a PCB track in the Altronics kit. Transmission is extremely temperamental though I may have made a bad solder joint somewhere. When it does transmit on … “Altronics FM Microphone”

I received some double row headers in the mail so I could finally build up my AVR Dragon. The solder pads were quite small but I seem to make for a fairly competent solderer already. Also I made a 30cm ISP cable. There are plenty available on eBay for less … “AVR Dragon Headers”

Second kit from Altronics, ‘PC Birdies.’ With my lesson learnt from last time I started with the short components and worked my way up. Two microprocessors is an odd design choice, they have to do this complicated synchronisation thing between them and they both have watchdog timers running and really… … “Altronics PC Birdies”
