Cherry announced their latest revision of Cherry MX tooling: on their blog today. The new thing is that the springs are now barrel-shaped and lubed with a lubricant "on par with GPL 205". They announce 100M actuations and eight guiderails as something new, and not the normal manufacturing standard t...

Yeah, I added a stub for "NeXT Computer" only for completeness' sake, because it is convention to have them.

I suppose it will take a while before the links stop being red (?) ...

Done. I suspect that a search for "NeXT" could have got trapped because it was on a list of common words ... but I dunno. I added links to a non-existed "NeXT Computer" page, that should be about the company . Apparently it had the official name "Next Computer, Inc" at some time, and that two-word t...

I believe that most Japanese keyboards are based around the ISO layout. So, it might have been more appropriate for the Famicom model to be ISO. Most Japanese keyboards are based on the JIS layout , which has the same type of Enter/Return key as ISO layout, but a lot of differences: split Backspace...

It looks weird that they put a Commodore bread-bin VIC-20/64 - style Power LED on an item that is otherwise NES-themed. For comparison: C64 , 8BitDo . I like the overall shape of the keyboard and the features with the dials on the top left, but I didn't grow up with a NES/Famicom so I don't have any...

Are they individually addressable LEDs or are they part of a LED matrix, driven by a LED driver chip? If a LED driver, you could find the chip on the board (or the QMK source for the DZ64RGB) and then look up its documentation to see what the voltages is produces. LEDs in LED matrices are typically ...

What you're describing is called "underglow", "side-glow" or "side-lighting". "Backlighting" is what the PCB already has. I wonder if there exists a type of LED in the right size with reverse pinout to the LEDs already installed. Then it should be possible to desolder some backlight LEDs and replace...

Like training a large language model on your keystrokes so it can keep working for you while you sleep?

People tend to make EVERYTHING run on these RP2040's, so it wouldn't surprise me if there was software for machine learning for it already.

Welcome! I saw your keyboard mentioned on Hacker News earlier, and admired your way of reusing Lego beams.

Have there been any mods to it to it to make it work with a modern computer?

I would inspect the solder joints to the controller, to see if perhaps two pads have been bridged.

Looks like a typical Fujitsu rubber dome.

geekhack, being under the Drop umbrella, was included in the purchase. We expect no changes to geekhack for the time being, but will of course share if/when that changes.

Corsair's press-release : Drop will remain a separate brand within CORSAIR and all existing warranties, purchases and customer support requests will continue to be handled directly by the team at Drop. Drop's blog Drop will continue as a brand, team and community within Corsair. You may already kno...

I think I've seen some kind of hollow, threaded cylinder (kind of like a hollowed out screw) that you can screw the screw into and lock it into place (sorry for the terrible explanation). Like these ? More common in hardware stores are spacers without any threading though. There are also "rivet nut...

Does QMK or other open firmware have hooks or APIs for LED control? I’ve never owned a LED board but it would be cool to customize it. I haven't followed QMK's source code for a few years, but there used to be several instances for specific LED driver chips. The QMK firmware for the Input.Club K-Ty...

The other problem with the inverted-T is the "cramp factor." It's painful to use. If I understand you correctly, you are complaining that it is on the bottom row . That's not the fault of the inverse-T itself but of where IBM had relocated it. The original inverse-T on the DEC LK201 had the cluster...

I'd think it would be interesting for something with curved key-wells, such as a variant of Dactyl.

I think I've also seen a row-staggered prototype keyboard with MX switches on a curved backplane made up of metal plate strips (but I couldn't find it right now).

There are the Matias TactilePro and QuietPro . They were made for Mac, but the feel is not for everyone and they have a reputation of quality issues. Out of mainstream brands, Varmilo and Ducky have made individual models for Mac. But every keyboard with USB will of course work with Mac. You can swa...

Hmm. Topre Realforce with Macintosh legends only in Japanese layout, right? Not for everyone.

Looks like a keyboard for some kind of Commodore PET. The two "CRSR" keys give it away. Edit: FfIFVg9cpUY Has instructions with how to convert it to USB using a Teensy++ 2.0. Too bad that the Teensy 2.0 is discontinued. Edit 2: From this page it looks like the switches have springs and conductive ru...

Three buttons would have been more common on a Unix workstation. One rarely sees optical mice of that vintage. I never came across them, but some of the early ones required a special mouse pad with a metal grid in it. I think that type from Mouse Systems is most closely associated with workstations...

Looks a lot like the early optical mouse from Mouse Systems in this video:

It does not matter. You can connect row-switch-diode-column or row-diode-switch-column. You can choose any two pins on the switch. The only thing to worry about is that the diode is connected the right way round, so that it lets current through in the right direction . Bonus question. The following ...

Ah, so you want to interface the PS/2 port from the FPGA? From a quick search, I learned that the board has a PIC24 MCU connected to a USB port for programming the device from a PC and that (at least some) PIC24 are capable of being a USB host. But getting it running as one would be easier said than...

On the back side, does it say "Take back one Cadam to honor the Input God, whose keyboard this is" ?

- what material are the keycaps made of? Is it PBT? Can it be identified somehow from the manufacturing label? They are made of POM, which is durable but has a bit low friction. Cherry keyboards with L as the first letter after the number in the article number have keycaps that are L aser-etched, a...

That looks like a keyboard for the NEC PC-9801.
There were many revisions though. This seems to have a gap between the Return key and nav keys, whereas some PC-9801 keyboards don't. And some keyboards have more keys.

Among keycap sets out there, do beware that it is possible that they'll include a Caps Lock and Space Bar keycaps that don't fit the Cherry G80-3000, but do fit other brands's keyboards. XVX "Cherry Profile" is white-on-black, supposedly double-shot PBT and Cherry Profile and in a very affordable pr...

After looking around a bit in the Wiki, I think the switch is Low-profile ITW Magnetic valve . A Symbolics keyboard has the same switch, with a white slider. Edit: Kbd News article about the CPT Phoenix Jr. Wikipedia entry about the system. Please post more pictures of this gorgeous artefact! I'd vo...

Yeah, that looks like it was damaged with water or acid or something ... A "solder-sucker" while the solder is being heated with the soldering iron is usually what is used to get solder from a hole. If the holes can't be used, alternatives available here are to replace a diode with a surface-mount d...
