Put the 42v together today, one 50v/1000 cap and at 37v it is welding everything I use.
Hey BJ, what's that white blob thing with the terms on each end at the left of the board? Nice battery and LED by the by.
I've decided I'm going to do a rev 2 on my solder box. Have a couple of 2577s now and will have an LED display soon.

You never ask about a mans white blob

It is a on off snap switch. This board come pre wired for a switch. I turn the board on, set the voltage with the pot then use the black push-button to charge the cap. The three wire 100v meter works great and can be calibrated.
Mine is the simple set up soldering leads to the cap on the flash board. Ran the wires to the outside of the camera, soldered clips to the end. I used a Fuji disposable camera....I posted it somewhere in the front of this thread when we first started gathering cameras.....
It seems like what works for someone isn't always the same for another. You might try adding some capacitors...also using good firm clips makes a difference
I'm not judging your ability, but what size did you replace it with? Stock one is 10kΩ.
I replaced it with a 10kohm linear pot that I had initially purchased for a DNA12 build but had laying around. I had read on here someone said it was 10k and when I pulled mine I measured it just to make sure, and it read out at 10k. I put the original stock one back on the board last nigh but its toast

Sorry to hear that. I believe bap had the same problem when he tried replacing the pot on his. These boards sure are unforgiving!
Has anyone run a flash circuit with a 14500? I haven't tried it but I think it may work.
Mine is still in the camera shell. I haven't been able to get any other parts to actually build one yet. Not sure if or when I will have the time. I was really hoping the camera would work for me, as it is the quick easy way....though probably nowhere near as good as any of the others. I don't know much about circuits and diodes and resistors, and really don't know what the purpose of each part is and how to decide what is right. If I don't find the time, I will just buy one that was built by someone with way more knowledge about this kind of stuff than myself....which wouldn't take much.
Can another value resistor be used between the fuse and lm board? Somehow it didnt make it on my last order. What exactly does this resistor do with such a low value?
Having some problems welding the 30g nickel to the 30g kanthal. Have tried all voltages from 35 to 42v. I am using one 50 v/1000 cap. Will adding another 50v/1000uF give me a longer weld time and a better weld? I have 6 50/1000uF available and have some 50v/4700uF on the way.
Hopefully GSA or someone with more knowledge than me will also answer....but I believe it just slows/limits the current being taken out of the battery
