I've been having issues getting a good solid connection to the neg post and I've been going quite a bit of thinking about how to replace the IC pin in the design with something that'll be easier to make a secure connection to...
Everything I came up with got shot down because of the limited amount of space in atty. that is until I got the idea of something like a brass sewing needle (can't solder steel).
Figuring that brass sewing needles may be tough to come by, I opted for the next best thing...
I simply bent over the IC pin to make an eye and soldered it into place. Here are some pics...
0.9 ohm for the P+
... and a 1.8 ohm for the ProVari
... and the obligatory glowing coils shot...
The 'eye' makes attaching the wire to the neg post a breeze. Now I just need to run it for a few days and see if it will work long term. If I find needles that work, I'll give them a try too.
