Re: Good host for small XPG @ 1.4a?
Not too bad on the turnaround time from DX. This is one of my faster orders I have had with them.
Ordered on 3/18, shipped on 3/23 and received yesterday 4/6.
I've never built up a flashlight before, but I have built up some bike lights and other electronics, so the soldering iron is no stranger to me.
Got home from work late, and I really had an urge to get one of these 3 hosts I ordered built, so I fired up the soldering station and let it warm up.
Unpacked the host and looked at all the parts. Took apart the tail to make sure the switch and everything was clean.
There was some little bits of swarf and stuff throughout the host so I cleaned it alll out real quick.
Grabbed my AAA, led and driver from the parts bin and looked at how everything is supposed to fit together. Seemed simple enough.
Had to file down the outside of the driver board to make it fit into the pill. Got it to where it was a very tight fit and seated it down inside.
Flooded the edge of the pill/driver with solder all the way around.
AAA'd the led board in, and cut the wires to length and soldered them in place.
I didn't have any insulators so I just cut a circle out of the cardboard the host came in...LOL. Used my leather punch to poke a perfect hole in the middle.
Put everything together and viola. I had light without releasing the magic blue smoke. The whole thing only took about 15 minutes.
It actually works great, and I'm super happy with it.
Thanx for everybodies help and recommendations.
I used the 1.4a board from shiningbeam, along with their xpg 14mm board.
I didn't have a fully charged 18650, but I think it was around 3.99v. I took a tail measurement with my dmm, and it was pulling .06a on low, .38a on med and 1.38a on high.
You can see in the bottom photo that the led is fairly centered in the reflector, but my cheapo insulator is a little off.
I have a bunch of XML's here and ordered some 14mm bare boards from KD. I'm planning on moving one of the leds to a 14mm board and building another one of these hosts up with xml, and 2.8a driver from shiningbeam. I know I'll need to take some extra measures for heat management, and not run the thing for more than a few seconds on high....but it should be a fun project.
Here are a couple pics. Sorry. no build pics as this thing went together so fast..................
