Welcome

Conclusion

So, that's how I put together a tiny Doom bauble from a cheap ESP32 and a small LCD that acts like an even smaller LCD. As usual, everything (schematics, PCB artwork, case design, firmware) is all publicly released so if you want to have your own little Doom machine adorning your Christmas tree, you can.

Merry Christmas!

This is so cool indeed and also kinda insane (in a good way) :D ! Thanks for the detailed article & schematics !

That is so cool! And you just gave me an idea for getting Doom into a R/S Model 100. If the screen could be cut down to fit the 40 char x 8 line (is pixel-addressable) LCD, the rest of it, like this, could fit on a card that goes into the bus extender slot and takes over. Hmmmm. Gotta fix that M100...

I'm thinking if you could find a screen about twice the size, you could make a bauble closer in size to that ornament, and then make it much easier for people to see what is going on.

Great Job - wish I had the fortitude to build my own. Is it available to purchase anywhere? Nick... Nick@DroneExpo.us

This is awesome, thanks for sharing all the code and designs! I want to make my own one of these. I've also always wanted to make a mini PC running Windows 95, so might try to scale up the model to fit a bigger LCD and a Raspberry Pi.
