I know this is an old thread, but it still needs correction in case someone stumbles across it when searching for a similar circuit.Ĭolin's description of how the circuit functions is incorrect. If you have PayPal I would reinburse you for your timeĬlick to expand.Incomplete, wrong, wrong, and wrong. Normally off and the switch I substituted were normally on. The swith which cam with the kit hadįour poles where as the one i substituted only had two. Switch but the substitution made the circuit stop working. Tried to use a different, larger momementary Also extended the leads to the momentary switch. You are talking about the pin on the 4069.Ī practical condideration of adapting the circuit to the plastic chrome hubcap, Hubcap_2_21.gifīecasue the LEDs on the kit, out of the box, are soldered to the PCB had to extend the leads to the I assume when you say "puts a HIGH on input pin 11." I believe I am getting the idea that the slow down and eventual freesze of the circuit operation is causedīy the interaction between the 1u (C2) and 47u capacitors. Velleman drew the schematic the way they did when you see the convoluted result: I have redrawn the schematic using the manufacturer's pin diagram. In an effort to try to understand the relationship between the 4069 and the 4017 better
