Check out this little USB gem! Turns out it can be modified to work on your Whoop! Here's a little video I made to show you how:
I gotta say it is very similar to the original DISCO leds (linked below) but this little chip (once removed from the plastic gem cover) carries three of the pre-programmed disco-style leds and weighs 0.3872g without wires.
Once you remove the outer shell and the USB plug (just wiggle it off) you're left with this, ready to be wired up to your 1s main power!
Here are links to the ORIGINAL DiSCO LEDs
