I've taken a look at some 555 astable calculators trying to figure out the pusle frequency of this tingle toy thing, and I have a question for you experts...
The design of this circuit looks almost standard, but not quite. I can't find any 555 astable diagrams that match what I have and I'm not sure why this is so different. Anyway, take a look, maybe someone has seen this layout and knows why it would be set up like this.
Mine is on the first one, I've drawn it with the pins in the same location as a standard 555 astable drawing so the differences would be easier to spot.
