Swapping power cells and re-celling battery packs.

9 repair logs

Disassembled Famicom Legend of Zelda cartridge (HVC-ZL), teal shell and PCB, with a new tabbed coin-cell battery soldered on as a stopgap and a new electrolytic capacitor fitted; the removed old capacitor sits on the paper towel near the cotton swabs, with a precision screwdriver, a loose coin cell and an eraser nearby.

Sega Dreamcast VA0 Recap, GDEMU & Mods (For a Friend)

Friend asked me to pick up a Sega Dreamcast VA0 from Japan and make it new again. Full recap, fan and optical drive lubrication, GDEMU install with the required VA0 resistor array mod (5V to 3.3V for GDEMU) and a dummy load resistor for the 12V PSU rail. Also fitted a resettable fuse and a fresh ML2032 clock battery.

Two Japanese Game Boy Color cartridges mid save-battery swap. The left cartridge is open, its green PCB showing a fresh tabbed CR2032 coin cell (its edge wrapped in yellow plastic) soldered in place, with the removed old tabbed cell resting beside it. The right is The Legend of Zelda: Oracle of Seasons (CGB-AZ7J-JPN) in its clear shell, and a blue spool of desoldering braid sits at the edge of frame.

Sharp X68000: Recap, FDD & Oscillator (No Picture Yet)

A proper exercise in stubbornness on this Sharp X68000. Two rounds of repair, a full recap, FDD surgery (one of the floppy drives had clear signs of a blown capacitor with charring on the PCB), a new oscillator, and still no picture. The X68000 remains on the 'future date' pile.

Sony PSP-1000 Battery Rebuild: Fresh Cell Swap

Built a proper Sony PSP-1000 battery from an aftermarket case and a fresh cell. The cells included in aftermarket kits tend not to last, so swapping straight away makes sense.

Sony PSP-2000 Battery Re-cell: Sizing Issue

Attempted to re-cell some Sony PSP-2000 batteries but the 1800mAh cells were too thick to fit the OEM cases. Back to the drawing board on cell sourcing.

Sony PSP-3000 Battery Re-cell + PCB Casualty

Same re-celling story as the Sony PSP-2000: too-thick cells initially, then an appropriately sized one sourced. One PCB didn't survive the process though.
