Re: PRESALE: Copper Pen Host - The Cypreus Series 2x10440 and 1x10440
The following method requires connectivity on the inside of the host.
For the E2s I've built, I was using red diodes. One of which was a 2 pin 685nm diode, so no case pen, it definitely complicated things.
I had one polarity going directly to the driver through the spring contact. I then attached another wire, stripped about 0.5-1.0" of the wire, spread it out, really frayed it, and sandwiched it between the module and host.
I ran the wire out of the module front, where the diode is pressed. I then screwed on the module backing, allowing one wire out the hole to go to the press button board. The other wire was between the module, and backing, I screwed the backing on over it for a good connection. Then sandwiched the wire between the module and the host.
Worked for the LPC-826 leadlight, 638nm leadlight, and the 685nm (two pin) WL E2 rebuild.
Just make sure you have room for the wire to move a bit while screwing the aluminum backing on, you don't want to rip the wire out of the driver. I actually screw the backing on over it to PREVENT it getting ripped out.
If that's not enough, wrap some electrical tape around the module, let it sit, apply pressure, then pull/rub the tape off. Basically, remove it whilst keeping the residue. This will let you hold the module in place and keep connectivity. Or you could try epoxy, but the gap may be too thin to cleanly use epoxy.
Up to your discretion.
GOOD LUCK! HAPPY BUILDING!
