Got some work done on the electrical components today.
First the UV array which will surround the quad emitters. Using an old P60 reflector as a guide I shaped some 1mm solid copper wire into a circle and cut to length so the diameter measures 24mm and soldered the ends together. I then used an old optic as a guide to mark out the eight flat top UV LED positions.
I cut the negative pins so the total length is just under 7.5mm then removed some red sheathing from 28AWG silicone wire and slid onto the positive pins & soldered each emitter into place on the side of the copper ring. I then bent the legs into shape and soldered on some extensions and a resistor for each LED then added some 28AWG wire to each for connecting and finally did a quick test :THUMBS-UP:
I will straighten the emitters up later.
I also got most of the other components ready with leads, resistors etc Is this all gonna fit?? :))
More switch details, a piece of 2mm acrylic rod cut to size and a few layers of aluminium tape around it for a guide for the GITD resin mix then kapton tape around that to create a well for the resin compound, this serves two purposes, keeping the plunger from falling out and it will also be internally charged from the UV array/ quad emitters.
Tape removed and the resin filed to shape.
Some copper around the acrylic for a very snug fit inside the brass switch slide tube. Silicone grease will also be applied in the tubes.
Got the tritium locator switch made for the quad emitters with a 12mm x 2mm ice blue vial and 3mm copper tube plus some of the other fun stuff done :-)
Watch out for those corners in your pocket looks sharp.
as a real EDC in a future build you could size it to just leaving the chip on the credit card exposed (mounted to the back side of the light). then you could just pull it out and use it as a credit card also.
