Currently editting a supercut of all my footage of reversing the SwanCrystal 8 mins so far at 400% speed (mostly) and I'm only just getting close to the sanding back the board part. Should I do it as one 25 min video or break into 2 or 3 parts?

previously Cripple Mr Onion on twitter. Noodling on retro stuff and working on my running. I occasionally work on movies and tv shows and stuff.
Needed a mostly working Wonderswan / SwanCrystal to be able finalise the reverse pcb Ive been worling on. This one came up, listed as defective. Thanks to @asie.pl amazing knowledge there was a good chance it was just corrupt EEPROM data making the screen misbehave.
Atari 1040STE case that is very yellowed. Never seen a tide line like this though on the underside. It's out in the sun but the UV index is only expected to get to 4 today for a few hours so I dont expect it to do much. Was more about drying it after a cleaning. Might try properly in summer.
If only there was a handy warning. Me who just accidentally touched forbidden heatsink: Ouch!
Fixing Ataris. Got a 1040ste for cheap as a "not working parts machine". PSU was the only issue I've found so far but a borrowed one has shown proof of life.
WonderSwan power daughterboard. As I'm getting closer to finishing this SwanCrystal reverse I'm getting some suggestions that I should attack this one next. You know, for completionist sake.
It's been a while since I filmed part 1 of this series but finally the fun continues with part 2 of the SNES repairs youtu.be/GdmtW9yXncw

While I've been reverse engineering the SwanCrystal I also got hold of a somewhat working Wonderswan Color. I'm hoping to find a worse condition candidate to reverse from but in the meantime made a small video about the button issues some ppl have. youtu.be/evoQx3-9Pf0

I think the SwanCrystal reverse is done aside from cosmetic stuff and maybe adding couple of touches to the silkscreen. I might branch it to modify the button pads slightly. Schematic can still be improved as certain components internal function gets figured out.
We have the brand NEW PicoMEM 2 in stock now. Such a nice product from Freddy. Huge upgrade to the version 1 which we will still sell for the cost conscious buyer. Get them here shop.flamelily.co.uk/picomem2

The SwanCrystal schematic and PCB reversal can now properly begin. Slow process to get to the stage I've been most looking forward to. A bit of a skill leap required but also new fun things to learn.
Finally finished depopulating / documenting the SwanCrystal and sanded it back to copper ready to scan.

I've never been into the retro PC side of things but an Atari made 8088 (PC3) was too good to go past. Listed as not working it shows some decent signs of life even if it can only find a portion of the RAM. Will be a slow burn project including hopefully adding a picoMem in future.
Rainy weekend away avoiding a cyclone and seeing a massive lightning installation spread out across the bay in Albany, Western Australia.
Acorn 28-AKF40 monitor connected to my Amiga 500. This monitor only does rgb analogue via a D9 connector. It's basically a stripped back 1084S-P1 with no composite or chroma luma circuit. Had to make my own cable up which onviously meant making backwards to begin with.
Tales from the bench. 2 repairs today apparantly "not working" The breadbin had an intermittent failure eventually narrowed down to a cold joint or micro fracture of the trace in the IRQ line. The 64 C worked perfectly but not for much longer as some mystery corrosion was taking hold.
Testing out some crt monitors I got and this 1084 looks gorgeous.

Attempting a repair on a Commodore 1901 monitor - it work but only in greyscale. Pulling it apart today and it's looking like sombody plugged something bad into the rgbi connector in its past.
Is there anyone out there who’s good at the C64 versions of Cauldron & Cauldron II and wants to record some footage at 1080 for me?
Quickly tested 3 of them. a 1901 would only display luma, one 1084 was not healthy at all and quickly got shut down, and this one seems to work fine and look pretty good.
