Tim and I are still working on the Keydler, I'm told the grid on the front is 1/2" by 1/2" on a real Twiddler. The current design is currently using 3 PIC16F84's (We may be able to get rid of one of these, but as shift registers etc. are so pricey compared to 16F84's, might be cheapest to just use the three. I'll look at that...) One PIC to handle AT / PS2 keyboard interfacing (NO serial port needed except for programming the chord map - unless that ends up all being done through the 1200 baud keyboard interface; We'll try to do both.) One to run the memory processor for a meg of flash RAM, gives us tons of macro and chord storage <G>; One to scan the keypad (I had put a 24LC256 in that part, but figured out I can probably get by without that easily enough.) One advantage of this method is that a DataEgg or Bat clone would then just involve re-doing the one processor (the keyboard scanning PIC), and as I plan eventually to do a completely custom keyboard for Robin (I'm letting her decide what SHE wants in a keyboard, with luck I'll be ready to build it by the time she makes her mind up! Ought to be pretty exotic, with some buttons and headswitches and who knows WHAT else in there <G>) Tim's doing the case, I'm doing the internal hardware, just about done with the (4th re-work? of the) initial schematic (and will soon prototype it all & start coding. Starting on the AT interface this week; Order for the rest of the parts is going out when my paycheck arrives!) Should be pretty easy to code, I've sure been pushing the hardware design towards that end! I'm certainly busy (on this as well as on keeping Robin safe & in one piece!) but would be happy to help - or if you're good with PIC coding & want to help make a GPL'ed keyboard assemblage, e-mail Tim and I, get yourself an Eval copy of CirCad for Dos (Probably could use the Win95/98/NT version too) from http://www.holophase.com/dleval.htm, and we should be able to speed up <G> (We're going with that as it's free & we don't have a CAD package in common otherwise...) I really need to start throwing things onto a web page for my sanity on this project <G> Mark Adam Wozniak wrote: > > I'm working on a PIC based twiddler knock-off, and I was hoping someone > who actually owned one could give me some data about the actual physical > size of the thing.
