Can't we do that now? There's already a cottage industry of replacement power supplies in the vintage computing and video game sphere, I would imagine GaN products will dominate that space eventually.
- saturn8601 2y agoSeems like there is a lack of power supply design expertise there, maybe due to certification requirements or possibly just the margins on a replacement PSU is much less than something like a flash cart or HDMI solution. I personally wouldn't dare to design a PSU: I would probably burn my house down. My hope is that certified designs that target various DC voltages will cover a lot of use cases. EDIT: Oh sorry I misread your comment. You are claiming there is a large selection already? I don't see it as often as I see other 'mods'. Are you speaking about any particular vintage computing/gaming community in particular? For consoles all I see is junk coming out of China. I've been burned too many times by that.
- telgareith 2y agoIts not quite turnkey, but USB PD (maybe with PPS, which lets the device specify voltage and current directly instead of simply picking a profile) from a known good manufacturer, and a trigger board (crapshoot there unfortunately) covers 99% of stuff. Also, You can buy SMPS modules on mouser or digikey now for under $10. Or if you're lucky jameco will have it. Sometimes even rotten chinese garbage can be useful- I have a portable USB supply for my DSLR that was originaly powered by seriously unsafe means- but the battery drm/sensor fakeout is good, so I just used the 9v USB-PD profile and a linear regulator. Canon makes one, I seem to recall it was AC only, produced whine in the audio capture in video mode, and was nearly $100.
