After you have resolved your power issue, could you give us a complete wiring diagram for this power alert led ? Do we really need to unsolder the smd leds or can we solder on it ?
You can also solder wires before the resistors, that will work just fine. Note, though when you are using an RGB LED with common anode/cathode you can only attach either power and low bat or charging and full, but neither one combined without an atmega, because one pair is in common gnd and the other has common vcc.
Ladies and gentlemen, I would like to inform you that I am currently moving very far away, and therefore I am very busy.

UPDATE: I am still alive! My ISP is setting up my internet on the 19th of January at my new place, explaining my offline-ness.

If you write me a PM, I will very likely take some time to respond.

Also, my 2nd build will soon go on, so if you've been following it, please stay tuned! :)

Many thanks for your understanding!

Also, let me sketch a wiring diagram in fritzing in a sec

Let me know what you end up doing to solve this.

here I am using an ATmega168, but it is basicaly the same thing.
Also using an powerboost 500C here, again it should be equivalent though.

So how will you get usb .

I thought you would go to the Red line , Good luck .

With the red line I might be able to solder USB right to the chip, but its more risky, I'll only do it if I feel I have to.

For today, I added a small capacitor to my power rail, just to be on the safe side.

Image

Then next up was audio. :) I soldered wires in all possible ways to my amp only to hear terrible static noise/bad sound quality in every constelation I have tried, untill my friend thaught me about pickup noises, static pickup etc. and I sucessfully removed all static by keeping wires short, doing proper grounding, laying wires differently, so they won't interfere etc.

Long story short, it took me a long time to have it working perfectly, but at least it is perfect now. :D

in order for the amp to shutdown when headphones are plugged in, I had to desolder pin 12 from the board, which is labeled as 'Shutdown'. I had to desolder it because VCC (5V) enables it and the switch in the headphones switch GND. I do not want a short-circuit in that.

Image

Image

Like that it will be constantly off. So we need to have a so called 'pull up resistor', which pulls the pin to high when nothing is connected and the amp starts running:



Image

I soldered wires to my volume wheel:

Image

and glued it in place:

Image

then I glued my speaker in place and wired it up:

Image

Then finaly, I wired up my headphone port and glued it in place:

Image

Image

So that is it for today.

all that is missing now is the leonardo, the button pcb and a few tactile switches and the project nears it's conclusion :)

Had a little setback :/

When I was drilling the holes for the X and Y buttons the tension made the screen crack. :(

Okay, so we ordered a new one...

Meanwhile, I have made something else:

I added a tactile switch to the top left, which performs a safe shutdown. It works via GPIO and a python script.
You can read a guide about that here:

Also, I made two shoulder button PCB's:

And glued them in place:

Just a quick little update:

My Leonardo Pro Micro came in the mail today and I started playing with.

I basicaly edited my Arduino's HID.cpp and USBAPI.h files and wrote an arduino sketch along with it. Works like a charm :)

So far I only have the analog sticks hooked up of course because my button PCB takes a while to get here from the U.S., but I also tested them by shorting pins to GND and it works! :D
