When I requested the dimensions of the battery, they asked what discharge current I preferred and it was recommended that it utilize a 5A (2C) continuous discharge current with a 10A peak PCB.
Ok, just to clarify, you are recommending that instead of having the two LiPo cells (3.7v 10000mAh (37wh) each) setup in parallel (equalling @3.7v 20000mAh (74wh)) to set them up in series (equalling @7.4v 10000mAh (74wh)). This way, the regulators are supplied ~7.4v to disperse down to 5v...
What if I used a charging circuit pulled from a powerbank that initially had a 20000mAh LiPo in it? I didn't use it because I was unsure of the cell inside, but it cuts off charging once the battery reaches 4.2v. It outputs both 5v 1A and 5v 2A via the two USB A ports.
I came into contact with a Lithium-Ion Polymer battery manufacturer in China and was able to get a custom-made flat-pack Battery. This is two 10000mAh batteries put in parallel to make a 3.7v 20000mAh (74wh) battery. It measures in at 4.44" (112.73mm) long, 2.57" (65.17mm) wide, and 0.87"...
Hey @Shank, what voltage are you powering the IR LEDs with? Is it 5v or less? I see on the trimming guide there is a 12v PWM point (and gnd) for the sensor bar but I don't think that is necessary to power two IR LEDs.
I'm building a system in a Wii U gamepad and it has two IR LEDs built-in...
I'm having some difficulty determining the pinout of the slide potentiometer I'm using in my build. I pulled a datasheet from the manufacturer and found that the bottom two pins are ground and the top right pin is unused (a "dummy"). That leaves the top and bottom left pins and the bottom right...
I had the screen from the BOM, I found the driver board was absolutely huge and made the already tight space inside the shell tighter. This screen (same screen) comes with a much smaller driver board and supports VGA and runs on 5v without modification. Doing a test fit, I can get the driver...
@BocuD I put on a good audio book and resoldered everything using 34 AWG magnet wire with your stripping/tinning advice. I checked continuity on each lead and everything seems to be in good order; looks great too. Thanks for the suggestion and advice, this is definitely an improvement!
Just...
Do you have any tips on stripping magnet wire? I have 34 AWG magnet wire and have tried the sandpaper trick as well as heating the end with both a lighter or the soldering iron, both proved to unreliably strip the enamel on the wire and sometimes melt away the wire itself. Out of frustration, I...
This is coming along at a slower pace than I was hoping. I got most of the controls wired in the GC+. Since I don't have room for the dual-tact mod in this case, I wired the left/right stick tact buttons (L3/R3) as the L and R buttons, the triggers being LT & RT. The RB is Z and LB is unused, as...
