Digital Frequency Counter 1960's Style


This is another project that is progressing agonizingly slowly... It is based upon a VERY old Digital Frequency Counter that was all old germanium transistors and small globes. I was going to try and to an authentic restoration but the globes had all corroded and kept falling off... There were also some sad things happening in the huge nest of transistors. I did find the schematic but really it was all a bit of a bridge-to-far. I have ended up making some small AVR boards and got some 5mm white LED's from Deal Extreme and it looks pretty original.
