Hey guys and gals! I'm building a mintyPi soon, and I wanted to show my build progress here for everyone to see. I'll also be posting questions as I go. Thanks for checking this out!

Just search "22AWG silicone wire" on amazon

by soldering iron wire do you mean actual solder? Or wire to be soldered. If you mean solder, then I always buy this type:

MG Chemicals 63/37 No Clean (NC) Flux Core, Leaded Solder Wire Pocket Pack, 0.81mm/0.032" Dia.
https://www.amazon.ca/gp/product/B072M9 ... UTF8&psc=1

If you mean the actual wire, that you will use for all wiring, then this is what I typically buy. (28awg silicone wire)

Striveday Flexible Silicone 28AWG 300V Copper Hook Up Electric Wire

I have another question. I don't have Helder's PCB Board, and I'm making my own button PCB. I realize, that I need a place to connect a power switch and a few other things. Any help? A diagram would be helpful!

It will essentially be the same as Helders just without the nice PCB. Switch will go after the TP4056 powerboost (or whatever else you are using), and you will run power direct to the pi, or to some other type of power distribution thing (or whatever you plan to put in there.

B+ (from power source) -----------> middle pin on switch --------------> right pin on switch -------------------> pi or power distrobution

flipping the switch to the left will cut power to whatever is after the switch.

as for other wiring, you'll need to wire the button board you make to the pi's GPIO's pretty simple, look into adafruit retrogame utility, or just use the minty pi image, and wire your controls to the same ones Helder has used, which are below:

LEFT 14 # Joypad left
RIGHT 22 # Joypad right
UP 4 # Joypad up
DOWN 5 # Joypad down
LEFTCTRL 21 # 'A' button
LEFTALT 16 # 'B' button
Z 26 # 'X' button
X 20 # 'Y' button
SPACE 15 # 'Select' button
ENTER 19 # 'Start' button
A 12 # Left shoulder button
S 6 # Right shoulder button
#ESC 17 # Exit ROM; PiTFT Button 1
GPIO pin numbers not physical numbers

Is there like an email I can reach you with?

if you send me a message via the private message feature on the forums you can send to my actual email (when clicking the Contact speech bubble, email will pop up). But you can also easily reach me on the discord server, with the same username.

Could you make a small diagram for this? I'm new at circuits, and what about the sound card? How would you hook that up as well? Sorry if I'm asking a lot of questions.

It's fine to ask questions, but all of this is covered in the minty pi written guide and video. I'll post a link, watch the videos and read the write up. Even though you do not have a PCB all other information is relevant. Both guides are relevant.
