I made this custom arcade controller and definitely felt some cyberpunk/cyberdeck builder vibes while I was working on it.

​Credit to Banksy for the graffiti.

Credit to gp2040 community edition for the firmware I used in the raspberry pi Pico that powers the screen.

Credit to me for CAD design, printing, assembly, wiring, soldering, and testing.

The screen shows the mode (currently x-input), current button and joystick presses, as well as a history of presses. It can do macros and many other things.

Latency within the controller is too small for me to measure. Supposedly just a few microseconds.

Features:

• integrated art
• flush press, rimless buttons
• no surface fasteners
• print in place buttons allow the art to cross the surface of the controller easily

Still to do:

• move pi pico to edge of controller to allow for external usb-c connection. Right now the pico is kinda flopping around in there with an external wire connected to it.
• improve wiring / wire routing
• more support for joystick side
• Pinball style sidebuttons

Picture looks really weird and sparkly, not sure why.

If I do all that I'll be pretty happy with it!

edit: someone came in here and downvoted all the comments. why bro?

I was playing Castlevania 3 today and I tried CRT-Consumer(as recommended by u/TheTechDweeb) on my Miyoo Flip V1. I got very strange results (see image). I would've used CRT-Mattias but it does not seem to be included with my version of spruce.

I just switched to sharp shimmerless but I'm kinda missing scanlines even though it is a pretty small screen.

I hate CRT geometry distortion btw, I'm really just looking for a sharp(ish) image with scanlines!

What's your setup for a 640x480 screen?

I got one of these babies (a casiotone sa-51) and a raspberry pi Pico. Well I assume a Chinese knockoff with USB-c and supposedly 16mb (storage? ram?).

Here's a lovely review of it.

I'd like to increase it's awesomeness by adding midi to it.

I feel like it has been done but I can't find any info on it.

Looking for help and advice.

I see u/todbot has done something a bit similar.

Is it as simple as demuxing the key signals?

Here is Veritasium's video.

I'm trying to recreate this effect with gears, but it is NOT working!

Here's my attempt.

I anticipated that the large gear would roll backwards when force was applied and that the gear carriage would move forward.

I really just want to replicate his result. The top rack moving, the bottom rack remaining in place, and the carriage moving faster than that top rack.

Can anyone explain what I need to do to make this happen?

Office supply stores will make a 24x36 print of an "engineering drawing" or blueprint for you for $5. 36x48 for $10! That's quite large, bigger than you probably want to deal with.

In order to get them at that price they have to be black and white, color is much more expensive but as frugal foot-soldiers in this economy we can definitely come up with some very cool use cases for those right?

Here's a few suggestions:

• Print a map for your next D&D session. We play with a piece of plexi over the map.
  • Draw one yourself with dungeon scrawl.
  • If you're not feeling creative enough check out r/battlemaps to see what your fellow redditors have made.
  • Donjon will generate RPG maps/worlds for you randomly.
• Make a stencil for painting - ahem - outdoor art. I'm sure there are legit uses for this. banksy himself uses stencils to get his art up quick, or he did in the old days.
• Protest signs!!
• Huge coloring project - There are tools that will take your color image and make it into a coloring book style page. That's cool enough but making it poster size could turn that image into a fun (?) date or group / family project.
  • Google gemini and I'm sure other ai art services can do this
  • old manga might be another good source for this

If you can think of any other uses for a very large black and white print let us know!!

P.S. They usually give them to me in a big tube so... bonus CARDBOARD SAMURAI FIGHT.
