More problems! I have managed to build two circuits. One of them is an op-amp triggering circuit that takes audio or IR inputs to trigger an output, this works beautifully on it's own. The other is a 556 timer circuit I found on the web, very lightly modified. Again, this works perfectly as intended.
Join the two together, by taking the output (OP) from the trigger circuit to the input of the delay circuit, and sharing a common 9v supply, all works fine for a few minutes, then it stops. Turn everything off, leave for 5 minutes, and again it'll all work for a few minutes, then stop.
Time seems to be the key, rather than use of the circuit - turn it on and leave it for a few minutes and it'll not work when you return to it, or you can use it 100 times in a few minutes before it stops working.
Any ideas?
