150 in ONE

I’ve had one of these Radio Shack “Science Fair 150 in ONE Electronic Project Kits” on and off since I was a pre-teen.
As a kid I made many fun gizmos with it: radio receiver, listening device, various enthalling logic gates. The odd thing was that when I got to high school, I was only mediocre at electronics and did better at programming in BASIC. Yes, it was the early 80’s…
In university a bought the “150 in ONE” again and used it to create a variety of electro-noise makers. One of the setups I dubbed the “Annoy-o-tron”; it generated a single tone pitch controlled by the 0-10 “CONTROL” dial and rapidly toggled on/off by running things through the light sensitive “CdS CELL”. Hours of noisy fun!
Someone somewhere in Guelph was (un)fortunate enough to hear the “Annoy-o-Tron” used on the radio (CFRU) on a number of occasions. I apologize to that one person who might have been listening.
