On the subject of Blinken lights and toggle switches,
I have had
difficulties finding decent mechanical keyswitches to use for projects.
Essentially, I need to make a hex keypad, with a couple of extra
function keys. I know that now we would simply get a membrane rubber
thing made up, but once upon a time, I would purchase 20 mechanical
switches, and solder them to veroboard.
Sadly, I can't find a source of these switches any more.....
BG micro has a cheep hex keypad.
Same applies to ACSII keyboards - I am fully aware
that I could get a PC
keyboard and a microcontroller and have ASCI out - but that is 'yet
another pc keyboard'
Let me know if you find any, the last good keys around seem to be
in the 1980's time frame.
Any ideas?
