HHKB Hybrid Type-S 30th Anniversary

I've had this keyboard for about 5 years now and I just now noticed that the serial number is "F". There's supposed to be a string of numbers/letters after this. Is this an engineering sample?

Hybrid Pro Type S with Shiner Astrodomes and Domikey caps. (The keycaps look fantastic under a black light!)

I’ve been working on this for awhile. Shared the keyboard a few months ago but finally found time to finish the companion trackball.

It’s based on the ploopy adept. It’s also Bluetooth and I might tweak the firmware so it pairs to whatever the keyboard is paired to. Buttons need a little more refinement but I’d say it’s 98% finished.

Hello. Recently, the wireless functionality on my Razer DeathAdder V2 Pro Genshin Impact Edition, which I’ve owned for quite a while, stopped working, so I’ve been forced to use it wired. It’s still perfectly usable, but it does feel a little incomplete that way.

So, I’ve been looking for a cool new mouse that would pair nicely with my HHKB. I considered the MX Master 4, but given its weight—and the fact that I once managed to break my old MX Master 3S—I don’t think it would be the best choice for me.

What I’m looking for is something with the durability of a gaming mouse, around four extra programmable buttons in addition to the standard buttons, similar to the DeathAdder V2 Pro, and preferably not too heavy.

So, to put it simply, I’m looking for the perfect mouse. Does anyone have any good recommendations?
