Have to agree with DMA - when I popped out an F122 sense card to hook it up to an experimental controller I was amazed to find that it's nothing more than a thin flat PCB retained by a couple tacks in the bottom plate. Most cheap fabs offer an option thin enough to flex easily, and given the form fa...

Please forgive my ignorance here - from what I understand, you need to know three things: When the damper is released (key pressed partially) When the hammer is moving When the hammer strikes the stop It sounds like this could be accomplished with three optical digital switches positioned such that ...

With pins the TQFP is 16mm on a side, and including minimum reasonable pad dimensions 17-18mm for the total footprint. Maybe it will still fit on a 60%, but it will take some finagling - will cross that bridge when I come to it. I use an STTC-126 cartridge for 99% of soldering which has a tip diamet...

Optional electronically, but sticky == icky imo. I'm definitely over having to wash my hands every time I pick up some of the prototypes at work 60% will definitely use QFN as 16x16 is way too big without sacrificing split space options. It looks like the QFN has the type of pads that extend around ...

That's always the fun part - did I lay out the circuit wrong, screw up the solder, melt the bond wires from the die or simply blow up the chip? AAAAAAAAAAA Probably I'm a little naive after watching some Louis Rossmann videos, but I think I can get it figured out without destroying more than a coupl...

I'll be redoing the board this week to put the PSoC on the PCB and maybe add a few other features. Use TQFP, Luke! Those QFNs are the easier-to-solder QFNs, but still pretty damn hard to solder. I have a good stereo microscope and STTC-045 for inevitable touch-ups, but your mileage may vary conside...

Made a RF87U PCB for CS, and it is now working perfectly (with extra help from DMA!)

Very exciting! Just want to make sure - these are going to be only one profile, right?

Count me in for one set.

One solution to all of this is to rest your thumb on RCtrl instead of 0. You can set RCtrl to switch to another layer when holding and put all the math ops (and even more fun stuff!) on said layer, under your fingers. I plan to use the Enter key on the alpha block for the numpad as well (it's a shor...
