Gameboy oscillator documentation

(ArduinoBoy left, power and jacks center, cpu-mod right)

This is a 15cm module, 5cm for the arduinoboy and 10CM for the gameboy with mod. the idea is to add two more gameboys later by leaving out the arduinoboy pcb and use a smaller face plate with minimal modifications to the project.
Sadly i got no feedback but i pushed trough anyway… the boards are currently produced by JLC. we’ll see how many errors i managed to build into it… the first one to guess the number (of errors) correctly gets a free copy of the module once it is working…

I’ll say three - but I hope its less

This is awesome! Excited to see the finished product!

The patient is on the table… call the dr.

[Willi359]

the CPU-mod seems to be working… i had ONE (functional) error so far… next up the arduino boy

[Willi359]

i am still testing the arduinoboy but i think this is working as expected. no additional functional errors in the pcb design (not 100% sure on that yet). there will be many improvements in the second itteration, mainly better footprints and optimized positioning.

EDIT: (two days later… to many consecutive replys)
so close… i thought i’d have this thing runnign by now… link cables, why are there so many variants? i got the wrong one… i have to wait for the correct one to get delivered… next week or so
I am gaining confidence that my pcb-design is working… the arduinoboy behaves (blinking on button presse) similar to one i bought off the shelve (catskull).

i’ll start designing a face plate…

improvements over the last itteration:

• pots raised on daughter board
• mute switch(es), still searching the correct footprint for a SPDT (<=?) switch
• secondary power connector to daisy chain the modules
• optimized placing of multiple components (LEDs, Switches, Power connector, …)
• the modules will be 16cm for the master an 12 cm for each extension GB, that meakes 40cm for a complete triple osicilator

@zorch : You are the only one who participated in the “guess the # of errors game”… guess who won . I’ll get in touch with you once i’m confident it wont bite you

“Sometimes just being there is enough”

No hurry, and no worries. Im thrilled with how it all looks so far and it’ll push me toward making more use of my gear.

[Willi359]

there will ba a third and hopefully final itteration… we are in business

pitfalls and learnings: trs midi… , patinece…

[MeltedMind]

Oh man, I’ll buy one of these as soon as they’re available!

[Willi359]

We are getting colse… still some final test but i think we are ready for the release (of the gerber files), expect them within this week.
double checking… done

demo & demo
gerber files <=maybe you have to C&P this link. no https. do you trust me?

EDIT: gerber files and second demo added
