Got the mouse today. First impressions are good , its decent build quality and feels nice in the hand. At 4000dps its way too sensitive for me, 1600 is the sweet spot for me. <snip> Anyone want to buy a performance MX? It sounds like you need to reduce your mouse speed or acceleration settings. Per...

Getting consensus on the legends might be the difficult step. SA and others seem able to churn out custom keycaps.

Yeah, well, they often just switch the LEDs with a FET that can take the current. PWM and bigger resistors have the same effect - reducing average current, and reducing brightness. PWM might not be the best choice if peak current is still over the 500mA USB limit! <snip> Do you want to be able to d...

How do you keep track of what is programmed on each key? The factory keycaps for some keyboards have 3 or more legends printed.

Why folding? I'd think that a thin 60% keyboard, with a protective cover over the keys, would be easily transportable. The folding aspect introduces a lot of complications.

That would require multiple coats of finish, and wet-sanding between coats.

Since the original IBM keycaps are dye sub'd, you could buff them to a high shine using a cloth buffing wheel. You'll need to research what buffing compound is appropriate for that type of plastic.

Would be interesting if that could be part of the resonance circuit for the Model F capacitive switches. But I'd guess that's very low power.

To reduce the sound, look beyond just the switches. The body of a guitar makes the strings much more efficient at producing sound. Similarly, the keyboard PCB, switch-mounting plate, and case affect the pitch and amount of noise the keyboard radiates. For example, you might experiment with packing t...

Phew! That surface mount stuff is something I need to practice before I'm the least bit confident. It's a lot easier with a stereo microscope and a really good soldering iron. Also very fine solder or solder paste, solder wick, and good tweezers. Stereo microscopes are abundant on ebay -- a model w...

Paypal should be able to see that from their side too. They should be able to give you the transaction unique ID.

I'd like two of the Kishsavers, please.

I always wondered if they really existed, of if it was all Photoshop. Next, you'll be offering Himalayan Yetis.

Another thought -- ask the seller if he'll remove the keycaps. That would significantly reduce the shipping. I believe someone organized a group buy a couple years ago doing just that.

I believe this is what you're looking for: http://www.ebay.com/itm/151071023024 That fellow has been offering these for a while, so he must have a number of them.

Kinda' sounds like a ground fault; the electrical ground in the keyboard circuitry is not solidly connected to the electrical ground in the computer. This allows the logic signals to float around as the ground bounces in response to data signals. Alternatively, the termination on the data lines migh...
