Here's a fun keyboard. Clicks, tactile and uses magnets
There's a video at the bottom.

Also has the biggest keycaps I've ever seen.

It uses a unique type of magnetic reed switch that I haven't seen before.
When the poll becomes magnetized, it actuates the switch.
The switch is tactile due to an embedded piece of metal in the plastic housing that acts as the resistance. After the magnet attraction is overpowered, the magnetic field then actuates the reed switch. The embedded metal is likely why many of the switches have cracks all over the housing... Though they are all functional right now (not sure how much abuse they'd hold up to...).

sounds, cool, looks cool, but how does it feel?

Wow, where did you get that?

Probably from Germany

ohmy! this thing is fantastic! I want to sleep over a bed of these keyboards!

HaaTa, you are a rockstar!

German ebay. I remember that thing, a very fun keyboard indeed.

Wait, what's all that stuff at the top? Is that a diode matrix to make it NKRO?

Another mad clicky monster, just what we like to see! Bizarrely, that nest of diodes may indeed be a matrix for rollover purposes. Very, very odd indeed.

From the sound of the recording, those metal inserts inside the caps really fly! Does it feel like a sudden snap, like buckling spring, or a smooth swing, like beam spring? I'm guessing the former.

just the sound, so orgasmic. I'm so jelly with you right now. Great find

Sorry to Necropost but I also got this little gem but in white keycaps..
Do you have some suggestion about how to clean it? I'm a bit worried how to do it best, some keys are sticky, but the working ones are really outrageous, no beamspring no nothing IMHO..
so did you open and clean or lube some parts?
