Boing Boing Gift Guide Toys and more! / Boing Hicks and Joseph Williams and the production supervisor was Sally Fliess. Output snals may be picked up as negative pulses at A or B or by current-sensing at C if re- quired for controlling larger loads. When input is grounded momentarily, output of one of opamps swings completely on and turns other opamp off. Green LED should have Its anode or positive lead toward pin 5 as shown for lower LED, where shorter but hher-voltage pulse Is avail- able.
