Figured I would throw an update out there, Louis Tully and I started our micro builds at the same time and he is currently blowing me out of the water.
I got another cell phone, exact same model so I can just use the already modified mainboard with the new assembly and screen. I went the smart way this time though and found one with a broken digitizer (touch screen glass) as the actual screen is in perfect condition when removed. $8 shipped
Here is the LED modification I did to the buttons.
Using SMD LEDs from a piece of 5m light strip acquired from ebay.
Cap of the push-button is easily removed and the strip trimmed down
I keep the strip in tact as it is easy to overhead the SMDs with the soldering iron. The pads act as a heat sink, and it also makes it easier on me because SMDs are a pain as you all may know.
Rest of the pad trimmed and the resistor flipped to the other side
I drill a small hole for the wires to exit the button, insert the LED with a small bit of hot glue to keep it in place.
Test of the LED, perfect!
All four are wired to a custom little pad that is turned on an off by a switch on the back of the cocktail. I got a bunch of the control wiring done as well, running out of space though. These little things are something else, takes a ton of patience to get stuff right.
Thanks for watching.
