Zeus: trigger your camera with lightning
I have always been fascinated by photographs about lightnings. While it is relatively easily to put a lightning strike in any photograph using image editing techniques :) I still prefer the real thing. Since photography is a hobby of mine, I wanted to be able to photograph lightnings. However, when I tried to do it without any specialized equipment, I didn't have much success.

Reading a bit about the subject on the internet I found there are many designs/solutions available, to get around the problem. Since the price of the commercially available ones are too high for my budget (and let's face it, it's not much fun buying something ready made when you can also make it yourself), I decided to make one for myself for less.
I found many similar designs on different web sites and finally I came up with my own, which is - admittedly - very similar to one particular one I found on this photography site (only in Hungarian). I kept most of the design, but replaced the relays with opto couplers and put the whole thing in a plastic box to make it easy to drag around.
If you are interested to make one like this, please e-mail me. I can provide you with customized kits that contain as many or as few components as you need/like (from just a programmed microcontroller to a fully built and tested PCB) to suit your experience/skills. Please note, I do NOT provide the enclosure as it is very time consuming for me to make. The code for the PIC is also available on request.
