Should be easy enough to check for shorts, just put one DMM probe on the pill/head and check for shorts by probing each LED wire solder blob.
Yeah, that’s the downside. I’m interested in a solutions that require less work. Your design is for custom MCPCBs anyway, if your going to go custom I’m still convinced that two through holes in place of two of those wire notches would be an easier solution. If people can successfully drill their own holes and solder without shorts, soldering with pre-existing holes should not be an issue. But yeah, I have to put my money where my mouth is and try drilling first.
Through isolated hole in metall core pcb is another technology.
It took many years to move from fr4 to metall core.
And several more years from metall core to DTP.
How long will take next step? Nobody knows…
Good news. I was able to convince Simon at Convoy to make a 21700 version of the S2. I asked him to make it fit Carclo quad optics so we can mod it into a quad. He is designing the host to accommodate a different quad optic with dimensions posted here. Does anyone know if this optic is compatible with Carclo quad optic? I want him to make a S2 21700 that is compatible with off the shelf quad optic and Noctigon, MTN, L4P quad mcpcb, of course with Kiriba-ru copper pills or spacers .
