Duodecuple? “consisting of 12”
Or a triple of quads…
This is a first batch Q8 that I have obviously had for a long time. I bypassed the springs way back then and nothing much ever happened since. I have not used it much
Last December led4power had a close out sale and I bought a bunch of 4000K SST-20’s on a variety of mcpcb’s. What to do with them? Here’s one idea I had. I also fitted a 4056 based, 2 amp charger board and a USB-C port.
I made a spacer using some 1/8” thick aluminum discs plus a thinner copper piece. A hole was drilled in the centers and a bolt used to secure the sandwich, which was then chucked in the drill press. A coars file was used to reduce and taper the stack to fit inside the Q8 head. The discs were then all lap sanded with grits all the way to 1200 to try and make the surfaces as smooth as possible.
The USB port is difficult to see. I drilled, then Dremeled and filed the slot in the side. Then used black paint to cover the bright aluminum.
Using some copper and some brass sheet I made a mount for the 4056 charger board. The USB-C port can be seen.
The charger board uses a bi-color led to indicate charging (red) or charge completed (blue). There were a few ways I considered to mount the led. For the method I chose I used a small piece of perf board to make a connection point.
The indicator led-board can be seen inside. It is not yet mounted…
I have not shown every step along the way. Here is the front end of the spacer with the 3 quads mounted. Holes were drilled and tapped into the aluminum spacer unit and 2-56 screws used to secure the mcpcb’s. A piece of heat transfer tape is sandwiched between mcpcb and the spacer.
There are a lot of wires. Three pair for the mcpcb, 2 for the charger output and two for the e-switch. This is the standard Q8 driver, no changes other than adding the charger connection points.
I really was not sure all those wires would fit into the cavity. But they did fit.
Here’s the front end with the fiber optic protrusing slightly. Led’s illuminated on moonlight.
Carclo optics… (#10621 clear spot)
Charging…
I just finished the assembly and other than turning it on for a few minutes in the semi-dark gharage/workshop I have not done much with it. Maybe tonight I will compare it to another, still stock, Q8. Brand new in box except for trying it out when purchased. A batch two Q8
I drilled a hole thru the spacer from the head cavity out towards the front. Well, actually I drilled it from the front end. This was to mount the led and a short length of fiberoptic to be the charge indicator.
