Worklog Card boy retropie handheld

[shrimp buisness]

This is the worklog for my retropie handheld using a raspberry pi 3b I had lying around, I am very new to this and am currently working out how it will be powered but I have a design measured and will later try and make a cad model for it, I am hoping the skills I learn from this will help me in the future to make a Wii portable which is my end goad but I figured I need to take baby steps yet, heck I haven't even got a soldering iron yet but I'll buy one with my next paycheck.

started work on the model but gave up due to not knowing the software that well, gonna do more research, im using freecad pls tell me if you know a better alternative

Fusion360 is a free and easy to learn CAD software that most of us use. There are heaps of official tutorials for it

i got fusion 360 on my laptop and started learning basics, i already have a very basic cad model with a hole for the screen and an open back for the separate backplate i will make by suspending cards in resin

im going to use 3ds stickboxes cos i like them and i think they might be easier to customize, ive just ordered them in red and black

3DS sliders may need manual calibration due to the range on them being lesser than a conventional joystick or joycon joystick

 

[shrimp buisness]

ive come along way already

the cad model is finished, im proud of what i have done, i am now going to order it off pcbway since i dont have a 3d printer, im not going to implement full removability of stuff because 1, glue is easy 2, i can transfer all the files i need onto it wirelessly, and 3, im lazy. ive ordered the 3ds sliders and caps although i am not sure how exactly im going to get the buttons, either resin casting or sanding wood to fit, custom button pcbs will be ordered after i get it in hand and get a idea of how much space im working with.

Scribbled together a in hand mock up

just found out how hard it is to have 2 joysticks and a d pad so left joystick and left d pad will share inputs

 

[shrimp buisness]

That last post was I lie there's enough gpio to go around for a d pad and 2 joysticks, here's all the button binding I programmed with a breadboard earlier If you can make it out

It's been a while but I've had peices arrive but not much work getting done

 

[shrimp buisness]

i got a screen but when I plug it in it doesn't turn on, it's 30pin, is it broken or am I stupid

The pi probably needs to be flashed with a module to support said screen. There are many 30 pin LCDs and they all require different handling
