Trying out "the Orb" aka Super Whoopee
I breadboarded the Super Whoopee circuit although I left off the 3 audio amplifier transistors and the speaker. I wasn't able to find my 2n107 so I used a 2n241 instead. Here is the magazine schematic again:
Here is the breadboard:
I then connected the output to an LM380 audio amp. I used 3 switches of a DIP switch for S4, S5 and S6 instead of using mercury switches. Then I took pictures and captured sound for each of the 8 combinations of the three switches:
It isn't as much fun as I remember. Of course that was more than 50 years ago now :) Anyway, don't think I'll pursue the Super Whoopee idea any further, at least as it was. Although maybe if I get one of those TI sound chips ? We'll see.
