Looks good Will. I hate how the parallel Stars are designed. I would like then to have 2 contact points instead of 8! They should have 3 flavor of Star's
Series
Parallel
2S2P
Mac
I've been making 2S2P stars by drilling/scratching through two of the five the trace routes on the serial star boards, leaving only the inner-most trace closest to the emitter and the ones between the contact pads in tact. Like this:
Mac - don't feel bad. I did like 3-4 wrong wiring diagrams in my notes before I got it right, and when soldering, I was constantly measuring and checking everything 2-3 times.
Here is the electrical diagram:
Positive Contact -> 6 emiters in parallel -> 6 emiters in parallel -> Negative Contact
The trick is that those 6 emiters in parallel are made up from 4 from one star and 2 from another star. This is the part that makes it more confusing.
That had me going cross-eyed too. I was sure you were missing a wire or something or running 4 into 2 and 2 into 4 in parallel, like:
I guess as long as you have six in and six out, then the current across each die is the same.
All in all, this is an awesome build, Will! Really nice job! This is my kind of torch.
Congratulations to Javier on a beautiful purchase too!
