Circuit Boards
Hi all,

If anyone has an interest in electronics and would like to try out the calculator project at teenix.org, I have 2 spare prototype PCBs that I can post out free of charge.

Please email the link at the bottom of the web page if you are interested.

The calculator board will emulate all 6 classic models and the HP67.

Parts are cheap and available although the 4 digit bubble LED display modules are becoming hard to find and I believe production has ceased. The circuit can also control a common 2 x 16 LCD display as well, although the LEDs look much better.

cheers

Tony
