Update - this should’ve been my finished player with a little demo…
The player is finished… almost, that is…
The enclosure is finished (not painted yet due to indicision), everything is mounted, software and scripts work, wireless filetransfer etc work and everything is soldered to a GPIO connector which is ‘filled’ with hotglue on the top to prevent the pins to bend and thus short-circuit.
Then why only almost finished and no demo!?
Well, well… being my first time prototype tinkering on this level i’ve learned how often a feature or ‘solution’ raise an issue. - Then my trusty old soldering iron died, i need a magnifying glass to be able to see what i’m doing and latest i’ve learned about interference inside a closed cabinet = Strange switch behavure (worked flawless on breadboard). Yup maybe i should’ve seen that coming…
Next up:
- new GPIO connector, fortunately a still have a few.
- Connect 40mm ventilator to 3.3V instead of 5V as it’s unnecessary much ventilation. I don’t need to cool my fingers on the enclosure.
- desolder all switches and change wires to shielded. I have several spare TRS cables laying around, they might do it.
Hopefully I’ll manage to make it work sooner rather than later as i’ve other projects on my list eg virtual pinball.
Kind regards
Rock
Edit 13. Jul: i won Linux load failure and ofcause before i cloned the sd, wee… I haven’t dug into it as i already had a better sd laying for the player. Started from a fresh image on a WD purple sd (as suggested by Mr Curtis). I noticed that this time i actually knew some of the things going on, anyway it’s up and running again ready for the shielded cables.

100% Linux noob (Linexia?) - Promoted, by Tim, to ‘not noob’ ‘novice’, with a single vote from Robert.
I look forward am slightly nervous about what triggers the ‘dangerous’ promotion.

Almost anything is possible. It’s the subjective sum of the variables price, time and entertainment that determines whether it’s worth it or not.
