Hardware related DIY projects

Here you can find some of my electronics & computer related hardware projects.

WLAN cantenna - directional antenna made from stainless steel vacuum flask
Wireless webcam setup - camera server for outdoor use

Unfinished:

Weather station - based on 1-Wire bus by Dallas/Maxim
Multi-stage 5kJ coilgun - 11 stages, optically triggered (proto, under construction)
Parallel port relay board - simple LPT relay board (and web control demo)

Other:

Battery capacity testing - disposable AA, AAA & 9V battery capacity tests
Couple of home made battery recipes - a side project related to the battery test

Under construction: (stuff that will be added when there is something to add....)

- Some solid-state tesla coil stuff.
I have a couple of half built prototypes that have been under construction for some years now. I hope to make at least one of these to work when I get time/money/inspiration/whatever to continue...
