I see a nice competitor to the C64 laptop :D Oh it seems some of the eyoyo have an RTD266x chip… those supposedly can be patched to support 15kHz RGB input, which I'll want for my ORICs…

Addendum on the Apple bricks (like, for the Portable and early PowerBook models), because I forgot again for the Portable: These are tricky, because, for one, the joint is well hidden, under top part, not under the seam, so the best trajectory is about 45°: And also because it's not fused all...

I wasn't in the best conditions to follow the discussion but it was cool.

So powerful it even emulates an Atari \o/ … Kidding, that's my EmuTOS port to Apple just starting up. Not fond of having to download half of Internet, but I guess that's half less with Rust than with Node… At least now i have an emulator that works (couldn't get it to run on BasiliskII or QEMU).

Ah, I'll be away on that week-end… I'll try to join.

I've seen quite often people breaking into these plastic cases that are kind of welded together, usually batteries and power bricks, with various tools and mixed cosmetic results. I found a technique that minimizes the damage and allows assembling back the device for reuse. I documented it in a...

So, I bought this USB floppy drive to go along with my VAIO, but it has the melting rubber pads disease… Let's fix it with laser-cut replacements! A note on cleaning and buffing these VAIO plastics: The paint on them is really thin, just rubbing a tissue leaves silver marks on it, so be very...

Damn, I only notice that now :-(

Sadly yeah you still need to model mechanical things for accurate reproduction… Nice result!

I bought 2 of these 10" CRTs cause they look cute, but one was missing the rotating stand, and the other one was missing the button door, so I figured I'd make them. It looks great with my ORIC Atmos (I used the proper ColorFabb filament…)… Oh and I had to measure the 1 meter front face...

I just learnt that Torlus left us. He worked on several FPGA cores (Genesis/MD, PCE/tg16, and Jaguar), and some QEMU targets like the Raspberry Pi. He was diagnosed with Parkinson decease 10 years ago, and held cafés for young patients to discuss. I met him several times, at the Alchimie...

Well the best one is ColorFabb's. It's expensive, but it's very good. I have a 2kg spool I barely used, that's been lying here including in not so dry winter for almost 2 years, and it still prints fine.

So, just confirmed on my PB520c, Vbatt is drawn almost directly to charge the battery (it drops at 11.7V), but it's disconnected when it thinks it's fully charged, so I only have to implement current limiting, not a full charge control.

Just tested myself for the sake of it, it happily triggers overcurrent protection at 1.3A if I let it charge on a bench supply. So definitely needs some circuit to calm it down.

Updated the model to make it easier to assemble with the meter.
