This was more of a proof of theory. In the next rev I'll clean it up and use longer wires for the atty.
I was scouring my office trying to find a button and wire to make myself a USB passthrough. I spotted an old mouse on one of my shelves and thought it would be a great donor. I opened it up, and unsoldered the wire, then as a quick test I soldered a 901 connector to the usb wire and WOW little too harsh for my taste. I broke out the fluke 87 and started looking. The USB port was 5v and could source 4a, thats WAY too much. I looked at the little un-molested regulator board I had then back to the mouse and commenced to serious hackage. I wasn't in the mood to smell burning PCB so opted to just use a pair of diags to cut the board instead of my usual cut-off wheel. I removed all of the components and cut the traces to the buttons. I wired the buttons in parallel so with the with a 200k pullup to +5 and switched to ground and then ran one wire to the enable jumper pad on the regulator board. A quick solder of the wires from the regulator board to the what was left of the mouses PCB, and a quick burn of the mouses .... to pass the wires out it's bum, and it was done. I plugged in the mess and it worked first time, but a little too hot still. I looked and had 4.4v coming out of the regulator so I dialed it down to 3.7 where I like it now it is fantastic. Press any of the mouse buttons and it fires right up
Here some pics
after hacking the board, trying the regulator so see how it tastes.
Weeee it fits
Fin
vape mouse in action I extended the atty wire and added an LED inside lol. Oh and you don't have to hold it up, the wire is about 2', I was strategically covering my company logo lol.
