Seriously, though, perhaps you could invest in a side table to separate the desk-y elements from the workbench-y elements, or something like that (meanwhile, I have to fix the cable chaos in my own setup, so who am I to point fingers?). I've got a better idea: there's a lot of space above those 650...

Here's my temporary set-up at a friend's house. The computer is a NUC (barely visible in the top left corner). Only the 19" monitor isn't mobile (it's a wonderful non-widescreen piece of art).

Thanks mecano. The hardware should be OK because it used to be OK, but, unfortunately, I can't find the source code I used to build the firmware back then, and I wanted to change the layout. Therefore I did it all over again, and now it's misbehaving, I just don't know why.

I also really want to try to write a keyboard firmware with a Haskell EDSL, since I spend most of my time writing Haskell.

I wonder why I missed this topic so far. While everyone seems to be flattered by your keycaps, I'm more interested in the firmware. Would you mind sharing your Ivory code with us? Just starting out with Ivory, I think I could learn a thing or two from you.

Here's a wake-up call from Nordic: they have announced the nRF52840, which now has USB device functionality on-chip, and can be run off 5V. That plus BLE sounds like my dreams come true.

Why ANSI? Unless you need the PCB, ISO gives you more springs, domes, and 1u barrels. Or is it the stabilizers you're after? (Or the crappy keycaps?)

Another capacitor of 0402 size? :)

Seriously, what have you done to your Novatouch? I destroyed one myself by removing all the Topre key goodness from it, but the electronics is still in good shape, including C15.

Since there is no resistor in the design, the rise time is only affected by the slew rate of the controller output and the bandwidth of the amplifier, which are both in the µs ballpark. I quickly tried the board again with six switches haphazardly fixed with M2 bolts and nuts (thanks to Sir Novatouc...

You're lucky that I just butchered my Novatouch a couple of hours ago, so I can actually have a look. Yes, C15 looks very much like a capacitor, 0402 size.

The excitation is a rectangle. Since the integrating TIA measures charge, you don't see the spikes typical of the RC circuits you and others (xwhatsit etc.) use. The limited skew rate is probably due to the extra resistor I installed for my tests in an attempt at combatting 50Hz interference. I'll p...
