"As said, I've abandoned the heatfins, which are an exaggeration IMO and have used the bottom and the lid of the alu box to let the power transistors dissipate their heat." From your post #100 there will always be a byproduct, however the size of it manifests. It may be less or more at any one point in a system (denoting efficiency of that system relative to another) but it won't go away.
[...] this looks like a nice tinkerjob for the winter months ahead anyway. I mean, isn't this what we all want for our world: less heat? I even might make one myself and use the heatsink that came with the Velleman K2543 kit (electronic transistor ignition). I have never needed that heatsink as I used an alloy box and its lid to cool my Darlingtons. What do you think? It's the finned black alu part on top. It measures 70X35 mm.

For my travels I wanted something robust with a guaranteed simple back up, other than eventually having to apply for a new black box in farawaygistan and then possibly having to wait days for the thing to arrive. In particular I didn't like the positioning of the electronics. Mine are high and dry - I can cross a stream with it - and they see no higher temperature than ambient. They are shielded against vibrations and moisture. And there's the joy of making the thing yourself ofcourse. Curios about the logic here. Starting with a Honda system that was effectively peerless when contemporary, placing another whole system to be more reliable? with the original as backup, appears inverted in straight mechanical logic. Backup contingency would surely be two sets of points and two condenser stored on the bike perhaps (maybe in the headlight shell to be always available) and you'd never be stranded such that requirements of outside assistance is necessary. I get that the electronic systems can reduce the duty load of the original points, but many of these in period additions where constructed and sold on attributes that will definitely improve a number of elements on car distributor systems that never existed in the Honda 4 cylinder ignition systems in the first place.

[...] Sorry, I said I would zip it but couldn't resist.
The zip by the way wasn't intended for anyone but ME .. it was a self-imposed gagging order on myself to call it a day not bore the pants off most people. With Sesman I am designing our own system with the most modern components I can get hold of and also, which are not at the end of production or obsolete and as miniaturised as possible. This will be detailed in Anorak's corner, where I (we) won't bore the pants off anyone, who is not particularly interested. That section on here was introduced on here , at my request, by SteveD, who kindly gave me admin rights, to discuss in-depth. techy issues.
As I'm a fan of electronic ignition can I be your first beta test customer. I have a new CB750 project waiting. Sent from my Pixel 6 using Tapatalk
Nah your the Alpha tester and development guy. I could be the first paying customer when it goes into Beta.Sent from my Pixel 6 using Tapatalk
