    Very ugly repair of ”Mahjong Channel Zoom In”

    Bought a jong pcb for 2000yen that was marked broken. And yeah, heres the problem @caius makes repros of these chips (JK-2) but I didnt really feel like spending 40-ish euros on fixing a game that would only be like 10000yen new. … but I had done such a replacement previously and had the...

    Multimeter recommendations?

    Slowly upgrading my gear to be less trash, and currently I have two cheap multimeters (one auto-rangeing, one manual) which are pretty slow and feel uh, low quality. Anyone have any good recommendations? Preferrably 200usd or less, but i can stretch that higher if required to get something decent

    Hakko FR-301 Desoldering Gun review

    I've used a cheap ZD-915 desoldering station from Amazon for a while now, and it worked somewhat ok at first, but have started giving me issues, so upgraded to a Hakko FR-301 and want to write a quick review of this thing. TL;DR: Basically, it's so much better. Buy this instead. While it's a...

    Quick repair: Mahjong Daireikai

    Had a Mahjong Daireikai pcb that didn't give any video on boot. Investigations showed that a JK-02 IC had uh... some broken legs. Considered trying to fix this manually but that seemed like way too much work, and @caius are selling repros for these so went ahead and bought one of those...

    Box for MP07-IONA-US

    I bought a 3D printer as well as a MP07-IONA-US, but it just comes as a bare PCB so modeled a quick box for it. This is basically the first print on the 3d printer, so I don't really know what I'm doing, and print quality will probably look nicer on a properly calibrated printer. Models are...

    Tiny Autofire pcb that fits under a button

    This is such a simple small project that I don't understand why noone has done it before. Take this: https://wiki.arcadeotaku.com/w/Passive_Autofire Make a small pcb and put it under a OBSF-30 button. Small enough to just be able to plug into regular holes. Super easy and nice. Plug button...

    Soldering jamma connectors without hating everything about the world?

    So I have some adapters and other stuff I’ve designed and have been meaning to put up for sale… but it requires soldering jamma edge connectors to pcbs and holy shit is that the worst thing in the world or what? Takes time, a lot of solder, a lot of fumes and is mind-numbingly boring. Is there...

    Mahjong -> Jamma adapters (Interest check)

    Mahjong PCBs have a real weird pinout which looks basically nothing like Jamma. Voltage pins, video, audio and controls are all different, see: https://forum.arcadeotaku.com/viewtopic.php?p=120446&sid=d7f05df295c31cda40f019f166ce492b#p120446 I'm currently using a hacked together adapter that...

    WTB: Jamma adapter-fingerboard and jamma connector

    Want to buy WITHIN EU, a adapterboard similar to https://www.arcade-projects.com/threads/jamma-fingerboards.7042/ + a jamma connector for a small thing... Might print some pcbs myself, but takes a while to arrive in that case, so thought someone might have some available already.
