Your schematic doesn't show any current limiting resistors for the LEDs.
This might have been part of the reason they popped the fuse. Unless they
were integral to the LEDs...

Is the code archived anywhere? All the links are dead. I stopped building
mine just before the coding phase, when I picked up a real Fluke keyboard.
Someday I'd like to finish it up. It sounds like your code should drop right
into a 16F84 easily enough.

Had to do a double take then for a second. I did that ages ago now :)

But since you mention it, it's probably worth me pointing a couple of quick
things out.

1. I ended up disconnecting the LEDs on my adapter. I think I popped the
fuse in my 9100 and couldn't be bothered to investigate. The LEDs ended up
annoying me anyway and I found I didn't need them. Not difficult to tell
when caps is on. If there's an obvious error in the design then let me know
and I'll modify it.

2. I never finished the code. The only thing that is missing is support for
the control key. In reality, I've used this for two years now and have never
needed the control key. It's functionality was mostly used in terminal
emulation mode (i think!). I started to run into problems with code size and
having to relocate the code within page boundaries. The reality was, the
project was a means to an end. I had a new 9100FT thanks to a kind seller on
here and I needed to start using it. As soon as it worked fully, I moved on
and started using it!

Despite those two things, like I say I've used the keyboard a fair amount
for two years now and have never been told of any problems. Maybe no-one has
ever built one? Who knows! I know how many times the code has been
downloaded ;)

Hopefully someone will find some use in it. 

I know the guy that came and fitted the hands free kit for my phone in my
BMW got a little sheepish when he started to tell me that the steering wheel
integration was just a PIC micro-controller in a box sending keystrokes down
an interface and he knocked a lot of money off for me! 

I would have loved to have knocked up some little PCBs to make it more
robust but I just didn't know where to start.

Enjoy,
Martin.
