Electronic ignition
Sesman:
I don’t suppose you have the component and layout details of the velleman kit? Although I’m a thoroughly unaccomplished electronics guy, I have in the past built a variometer (back in my reckless dare devil hang gliding days) and I wouldn’t mind a crack at the ignition project.

The original cooling fins in the Velleman kit are an exaggeration in my view, soI have used the alu box and its lid to cool the power transistors.
Sesman:
Thanks for that, very much appreciated.
I’m going to give it a go.

It depends on what kind of person you are. Two Velleman kits K2543 will cost you around € 38,- so cost wise Hondamans with the six wires and the connectors is hard to beat ofcourse. When I made mine, Hondamans or other similar products weren't around, so I had no other choice than to improvise mine. If you, like I did, would buy the separate electronic parts yourself in an electronics shop (around € 14,- in total), you'd have to solder them on some experiment board after you've interpreted Velleman's wiring scheme. So you must really like to make things yourself and face possible frustration. For instance: I wanted to fit both modules in the smallest box possible* which has been quite a puzzle. But again, it has been worth it: it has always worked and still does today.
BTW, I have not been in a hangglider, but have done paragliding in the French Alps.
*Actually there's quite some space behind the side panel.

I forgot to mention I'm building a new one for a friend, after I ran into two original Velleman kits I could have with a 35% discount. The advantage over buying the components separately is, that you have the prints which makes it dead easy to make them and they will fit in an even smaller box. When I made mine the first time using experiment board I had to improvise, like where to make bridges and where to 'interrupt' the lines.
