Wow!
I had seen those before, but didn't know they where yours. Great work!

I am gonna go with individual buttons then.

Still waiting for parts to arrive...

Last time I ordered from aliexpress I got my stuff in three weeks, but this time I will have to wait 6 to 8 weeks for the stuff to arrive, and only 3 weeks have passed.

My internship ends today, so I will have a lot of free time from now on.

I was expecting for the parts to arrive this week, so I would have something to do, but that isn't the case.

Feeling really tempted to buy another display for 6.5€ from a seller from my country so I can get it next week and continue with this project...

@AluLagoa yeah shipping on AliExpress can be variable. I tend to pay the extra and go for the 20-40 day option rather than the 30-60 day one.

I'm still waiting for some screens that I ordered at the start of January!

AluLagoa

Decided to order another display from a guy in my country.
Should be here in the next few days, so i can go on with my project.

AluLagoa

Hi!

Cheers!

Awesome work! 😀

AluLagoa

Thanks!

For about 2h of work is not that bad.

Just did a cardboard case for it:

How can i find the buttons that you used on you minimalistic build?
Mine are really hard to the press and kind start to hurt my fingers after a while... Yours look soft to the touch...

moosepr

@AluLagoa yeah they are soft. The only place I know selling them now is adafruit

https://www.adafruit.com/product/3101

I randomly found mine on eBay, but the seller doesn't have any more

AluLagoa

@moosepr
Thanks!
Adafruit wants $45 for shipping, and a seller i found in the UK wants $8 for 10 + shipping.

Well, when I do Version 2 I will 3D print a case, and I will try either to make bigger buttons to press on the tactile switches or use a SNES USB gamepad under the shell.

moosepr

@AluLagoa yeah adafruit shipping can be a pain.

Can probably get a few hundred from China for minimal prices

Possible next version of the handheld.

Smaller, much nice looking, possibly 18650 battery on the back.

AluLagoa

Well, trying do desolder the pins on the display was a bust... Acidentally striped one of the contacts...

Lesson learned: Don't mess with something that already works.

Where's the fun in that? ;)

Interesting project. Sparks up couple ideas on my head as well. Could propably build something similar from a Odroid U3 that I have lying on the drawer, so definitely gotta follow this topic. :)

barrymossel

Really cool. Something like this might be next project (after my full size cab). Still have a 7 inch screen lying around and quite some arcade controls :)

AluLagoa

A friend of mine will give me a DMG-01 case, hopefully that will be big enough to use the components with the connectors.

DD-Indeed

@alulagoa

Game Boy Color's case is big enough for sure, and I think that you can get new ones too. Copy models obviosly, but good for these kind of things.

AluLagoa

@dd-indeed The connectors on the pi and on the screen are vertical, and they take way to much space, I will be lucky if I can fit them on the DMG-01 without bending them.
