Over the past couple of years, I've spent an unbelievable amount of time (and an even more unbelievable amount of money) on a few little electronic projects. As my contribution to the great hive mind known as the Internet, I've decided to document a few of the more interesting ones...

• 6502 computer project - The first project I built up with a Roadrunner wiring pen, and possibly the most primitive multi-board 6502 computer ever devised.
• Battery tab welder - Hobbyspotwelders wanted $1500 for a battery tab welder. I didn't have $1500. So I built this thing... for £50. Featured on HackADay.com!
• Micronic 1000 - my attempts to reverse engineer a portable handheld terminal.
• GALBlast - Another "I'm not paying a King's Ransom for that thing!" project. Program GALs for £35...

I've also written a couple of technical articles, which I'll be uploading here as time permits. For now, here's the first instalment:

• The Hitch-Hacker's Guide to the Atari Digital Vector Generator. This is the write-up for a reverse-engineering project I did on the old Atari Lunar Lander/Asteroids Digital Vector Generator. Very useful if you want to reprogram or repair a Lunar Lander or Asteroids boardset.
