Last week I've made a new prototype board for driving some new feedback solenoids on #GolEGol I've made a thread on mastodon with more pictures and videos: chaos.social/@maxiborga/1...

First test of using #FreeCAD for CAM work. In the path of slowly replacing fusion360

Screenshot of FreeCAD 1.0 app, showing the CAM workbench and some operations paths

photo of the result of the CNC job that the freecad screenshot shows. It's a piece cut in black melamine mdf

another view of the result of the CNC job. In this case you can see the whole where two pieces were cut and a third piece still attached to the board by some tags

I made this framed print as an award in NAVE Arcade's 12th World Tournament In the illutration you can see all 21541 registered scores, with each line representing a register and the line's length representing the score. Each name has a palette colour asigned randomly #gamedev #arcade #navearcade

Photo of the framed print with the illustration of all the scores.
The illustration is a colorful representation of all the NAVE Arcade scores, with lots of horizontal lines really close to each other, in a six color palette

Detail photo of a corner of the framed print. You can see the text "NAVE ARCADE. FECHA: 26-NOV-2024. SCORES: 21541"

Close-up of the illustration.
You can see the individual lines representing the scores and the texture of the paper

Another close-up of the illustration, but not from the final print but a test.
You can see the individual lines of the scores and part of the text: "NAVE ARCADE SCORES (21541)

Yo tengo esta versión. Me la regaló mí viejo muchos años después de haber jugado.

Edición de Maxi Juegos Erbe de Altaya
Se ve el contenido de la caja: los 4 discos 3.5, una revista con información sobre el juego y el disco de cartón anti piratería clásico del Monkey Island

I was able to modify the ice40-playground code to work with this panel. The repo includes a python app to stream video to the panel really easily. Here I used that together with gphoto2 and ffmpeg to send the DSLR live preview to the screen

Last year I played a little bit with an RGB led panel and an IceBreaker FPGA. Here I was testing it with some of my digital sketches

besides arcade games I'm also involved (not much lately) in learning ASICs with open source tools. I participated in Google's MPW program and @mattvenn.net 's Tiny Tapeout, creating my own designs and chips This photos are from the first chips I got from the MPW program:

During the pandemic we made a robot so people could play #NAVEArcade remotely. The idea was to develop some modular open source system so other machines could use them too (never reached that stage) Her name is ROBOT.A
