Getting stuff done when you're watching your niece and changing diapers isn't an optimal combination! But I managed to write a little library that handles the display driving etc. So now I have to reprogram everything I had running before, like the enemies that are moving and drawing to the frame that then get's shown.
Considering changes for a possible PCBA

Just in case I need to scale this up and ever get to the point where I consider a PCBA service:
here are the LEDs I would probably want to use instead: LG T770, LY T77K, LP T770, LW T773, LG T770, LO T77K, LY T77K - well some of them.
this might be continued.

Any video of this working? Very cool.

Are you sure? yes | no

Did you know that Nintendo built big incandescent light bulb versions of game & watch games out of plywood during the development of each of the games to test out the graphics and gameplay? I read this in an Iwata asks interview and always wanted to build an LED version of octopus.

Are you sure? yes | no

deʃhipu wrote 06/25/2019 at 10:09

What would you say about something like https://castpixel.itch.io/wobble-jump

Are you sure? yes | no

davedarko wrote 06/25/2019 at 11:33

I don't get how to play it, but I guess that was the "charme" of a lot of those games :D definitely something worth checking out, as the graphics are fixed as well.

Are you sure? yes | no

deʃhipu wrote 06/25/2019 at 11:41

There is some explanation in the text below.

Are you sure? yes | no

Eric Min wrote 06/21/2019 at 02:08

If you made a bunch of game&watch style mini-games I would buy one in a heartbeat

Are you sure? yes | no

davedarko wrote 06/21/2019 at 20:00

anything that comes to mind that would make sense to start with? What's your favorite? :D

Are you sure? yes | no

Mic wrote 06/19/2019 at 15:52

It looks really nice, but how do you represent the missile from the player and from the enemies ?

Are you sure? yes | no

davedarko wrote 06/19/2019 at 16:47

I just hope it's fast enough to distract you from the looks :D this project was heavily inspired by this Space Invaders handheld by ENTEX

Nice. I can imagine a whole range of game & watch style games using backlit masked pcbs in the near future!

Are you sure? yes | no

davedarko wrote 06/19/2019 at 16:46

I was wondering what games one could do like that - I will probably try to code some sort of galaga version as well. It looks nice as a badge with scrolling text, too! Frogger might work with RGB LEDs. But charlieplexing a decent amount of RGB LEDs sounds too crazy for my taste :D

Are you sure? yes | no

thelogicofpi wrote 06/19/2019 at 18:02

addressable WS2812 ?

Are you sure? yes | no

davedarko wrote 06/20/2019 at 08:36

@thelogicofpi I imagine those are especially tough to solder upside down ;) in that case I'd rather do what @sjm4306 did with his #Small Word Clock project, use two pcbs and a 3D printed spacer.

Are you sure? yes | no

deʃhipu wrote 06/20/2019 at 10:21

The PCB sandwich approach also has the advantage that the spacer can include walls between the areas being lit, and thus reduce bleeding.

Are you sure? yes | no

davedarko wrote 06/20/2019 at 10:47

I wouldn't see bleeding as a problem with this build, the LEDs are far more apart than with the PCB word clock I made. A benefit would be that you can swap the face plates and make it a word clock or something else quickly.

Are you sure? yes | no

thelogicofpi wrote 06/22/2019 at 14:01

If you went sandwich approach you could also get it assembled easier.

Are you sure? yes | no

arturo182 wrote 05/31/2019 at 08:25

How thick is the PCB? :)

Are you sure? yes | no

davedarko wrote 05/31/2019 at 09:24

1mm, but should have been 1.6mm for more diffusion... why do I always change my mind last minute? :D

Are you sure? yes | no

铲屎将军 wrote 05/31/2019 at 06:56

I’m wondering how did you make the light go throw PCB layer ? And how did you make the different colors of back and front ?

Are you sure? yes | no

davedarko wrote 05/31/2019 at 07:48

Hi! You can order matte black PCBs at JLCPCB.com. I removed the black soldermask and copper on both sides so the LED can shine through. The LED is also soldered upside down!

Are you sure? yes | no

Jdaie wrote 05/31/2019 at 06:37

Really good idea to light from the back!

Are you sure? yes | no

davedarko wrote 05/31/2019 at 07:48

thank you!

Are you sure? yes | no
