Well, here we go again. I have gathered some parts and materials and have a rough mental plan.
Some of these were on hand; the 10 inch piece of 1 “x 1.5” aluminum tube is a leftover. So are the pieces of copper tube and strap stock. The driver, mcpcb, optic and charger circuit board were waiting in little boxes, looking for something to do. I did order the 2000 mAh Vapcell 16650 cell from illumn.com. This one tested out at 2128 mAh. Some 519A LEDs are on order.
I call this my proof of interest image.
I usually learn something too.
