I got FTKA/ФTKА and F61A/Ф61A fluxes back then, and experimented just a bit. Soldering over aluminum foil could be attained relatively easy. But what I originally had in mind was soldering to a chunk of heatsink and some hollow pill, and that was :facepalm: a whole different story. My attempts were mostly unsuccesful. I got some success on the heatsink by pre-heating it in an oil bath inside a frying pan, then soldering over some de-anodized and fluxed part of it. But overall never got really strong joints on the heatsink, I think that had to do with the heatsink alloy. The fluxes emit nasty fumes, and they may be hard on the iron's tip. Due to the overall difficulties I gave up on the matter at that point.

1. I’ve already sold a lot of springs by now. So, I’ve saturated a large part of the market already probably. I’ve sold over 8000 springs, so, you can guess what happened.
2. Since the springs are quite a bit more expensive now, people are waiting for me to have the springs to take the risk and pledge in a certain amount.
I mean, they are over 50% more expensive than the 1st gen spring.
I’ve ordered the springs anyway even if we are only 1/2 there to 1500pcs each.
I need to push my skills to the max to prove the worth of these springs.
I also think the enthusiast part of the market has already been filled.
Not everybody can actually solder springs, or wants to.
Unlike LEDs, the improvement isn’t instantaneous, so reflowing new springs vs new LEDs is much less rewarding, even though I think good contacts are still very important.
I’m planning to start light modding services now that I’m experienced enough and have acquired enough materials and supplies now.
Sorry guys and gals for the delay, but rather than preparing+shipping multiple orders at once, I decided to prepare every non spring order in one go, and then ship everything in batches.
It makes things easier for me, and way less prone for me to make errors.
So, I’ll start shipping multiple orders this Tuesday, so everything can go as planned as quickly as possible.
