Hey everyone! We've been having issues with being bombarded by forum spam bots. As a temporary measure we're disabling registration for around 72 hours. Anyone wanting to join up as a legitimate user, please have patience! :)
Hmm yeah, I suppose for more complex or visible parts that'd be something to try. But they you'd need to add the adhesive layer, so cut it anyway.
Btw, the round ones if they are what I think they are, you can find them quite cheap already on ali.
Yeah thought about molding as well but we lack the equipment here… Laser engraving works not too bad, except for the raster effect (although I want to try sanding that), and it takes time so it's not as cheap as I envisioned, but if I use the full width of the machine I can probably make it fast...
I've been modeling (if you can all drawing shapes with grey gradients in Corel Draw modeling) some feet since then, mostly for PowerBook stuff… and VAIO.
Latest prototype, can you guess for which machine? (left is original, right is first version):
Well I found the perfect connector in KiCad's library… then I failed to actually order one because they don't exist in 2x50 pins unkeyed 🤷♂️
I experimented with slicing PCI connectors (it needs 2 more pins than the actual amount on the main section…). Would work but it's finicky…And the other...
My initial idea was to make a board to support both with either connectors, but I'm wondering if it might not be too large, probably simpler to do separate boards…
To conclude the thread, after getting network working again, I did a last live showing off all the various software that was installed:
Arachne web browser
FastTracker II
Windows 3.1 with Calmira II, and a whole lot of useless tools.
Arachne doesn't like Google, but FrogFind works fine...
After some fiddling with the bad contacts and adding some washers to raise the board, it seems more stable now. It had some odd software installed: Calmira II, Chartist, FastTracker II, Arachne…
Two weeks ago I took this 486 away from its 25 years sleep at my mum's attic… It was quite well stored and covered, except little did I know back then about Varta, Destroyer of Worlds.
I then spent way too much time cleaning it, removing components…
checking and fixing traces…...
For hard plastics like ABS the UHU Plast works quite well (it's acetone based), but it can get out of the crack and leave marks on the outside. Also, I usually reinforce the parts from behind with some blister pack plastic also with the same glue.
Indeed I noticed the VAIO PCG-F707 I just got didn't only have the rubber feet that leaked, but also the CMOS battery that's well hidden inside the very front of the case, not even under the keyboard or some accessible place. I'll have to open it all to remote it…
While some people managed to recreate rubber pads with 3D-printed TPU, and it can look quite okay, I thought it could look better, and I wanted to explore other methods. I've had the idea for some time, for another machine, but I had this Color StyleWriter 2200 around with feet turning into goo...
The pinout is linked to in the first post.
Basically Vout = max(Vin, Vbatt) (with some threshold effects though) ; /RST OUT is 0 if Vcc < 4.2V or /MR is down ; /PFO is down if PFI < 4V or so.
I've been busy with other stuff, I need to finish the test gear then hopefully I can get some shipped.
Well it allows replacing broken chips (they are close to caps usually) with known good chips because they are new chips still in production, not some "new old stock" that possibly got de-soldered from a battery-bombed logic board that might work or not for who knows how long.
