[Harry Dalek]

Came across this 1965 wunderkind some thing i would expect Steve would of got up to back then
Looks to have a flying spot monitor in side the case with PMT and hes own Audio tape recorder and play back to a P7 Amazing no wonder he won the science project .

Harry, who is this boy?

You see that he has mounted an oscilloscope tube vertically in the "table". Then he lays a transparency on the screen and a round box in which the PMT.

I see more interesting unconventional set ups in his aparatus. The self built tape recorder is very special. Realise yourself that 1965 was about the moment of the birth of the audio Compact Cassette.

I love this one...

Autodialer (1965-66)
Stored up to 7 phone numbers by sticking strips of tape to a coffee can. The can rotated and brushes did make and break over the tape to create dial pulses. No TouchTone dialing back then!

It was built to win a radio contest. WLOF radio gave prizes to the first caller to notice 3 seconds of silence in their transmissions. This device was connected to a radio and telephone line. After it detected silence on the radio for 1 second it started dialing. If the silence continued for the full three seconds it completed the dialing operation. If not, it aborted. Dale won so many times he was banned.
