Analogue stick without addon board

Hey Flavor, sorry for the lateness of my reply, I've just finished a work shift.

I probably am in the "almost nobody" catagory haha. I've always had Pi Zeros in my builds and this will be my first powered by a CM3. The thought of having a unit powerful enough to play Mario 64 and Ocarina of Time makes me feel like I'd be mad not to try and add a stick, freeing the d-pad for use as C buttons. Big Grin

I couldn't justify the buying a CM3 board when I had a Freeplay Zero already (though I'd regretted not going the CM3 route back then) and the lack of a joystick option had kept me from investing in a BoxyPixel Shell (which was enough of an eyecatcher to justify a CM3 upgrade.) However, in a conversation with a long time customer (I work in a local grocery store) who worked in a nearby factory working with metals, he offered to make the hole for me if I marked the placement and size. He seemed confident that he could do so without damaging or warping the aluminium. This changed everything for me and gave me the push Big Grin

Sorry for the life story haha, Thanks so much for the board picture, that really helps! Thank god it's so perfectly labelled haha. I've been mulling your sound advice in my head throughout my shift.

It sounds like I could follow Porcinus's route and order the ADS1015 12-Bit ADC chip, follow his instructions to wire it to the adafruit PSP-1000 stick, then follow your idea to run the wires around to the other side of the Freeplay board to access the holes on the back, as the BP L2R2 will be preventing access to them from the front.

(@Porcinus When reading a sudomod post about joysticks, they mentioned that a Vita stick could be converted from the ribbon connection to the same four outputs (left/right, up/down, VCC and Ground) using this converter https://www.walmart.com/ip/Unique-Bargai.../135068700 Is that the FPC connector you spoke about? And would this work with a Switch stick? I think a switch stick would be my choice if easy enough to do.)

I'm embarassed to ask but.. I am a fair bit out of my depth on a basic level here, though I intend to be patient and careful. Specifically, what kind of wire should I be buying from Adafruit? And to use these holes, so I need to solder the ends of the wire directly to them or do I insert male pins into the holes (as I see in the standard freeplay L2/R2 board instructions) and then solder those in and then solder wires to them? Or do the wires themselves have pins on the ends?

...I'm really trying not to sound like an idiot saying this, heh. Thank you for your patience guys. The last thing to work out, I think, is where the stick would fit inside the shell best (presumably beside start and select) and how to keep it from moving around. And I guess insulate it from shorting anything? Kapton tape over it, perhaps? I might be in over my head with this but I'm hungry to learn. Smile

Thank you both for taking the time to read my posts and to respond with such thought and detail. You're both amazing.

As for Andrew, when/if you do read this.. Congratulations on your baby! That's amazing news.

I'd love to hear your input and suggestions on how to avoid roadblocks if you have time but I'd totally understand if you didn't.
