lightningtiger Posted February 5, 2012 Posted February 5, 2012 Funny and neat idea 'Allan', you only need a Kenny to look after those loo's ! By the way, your circuit diagram it would be a 390 Ohm not a 300 Ohm resistor....though a 330 could be used depending on the LED's If. Neat multivibator design though I must say, two transistors could have done the same too ! Great porta-loo designs too, wouldn't mind knocking a few together for my MOC's....Brick On 'Kenny'....er, I mean 'Allan' ! Quote

LED resistor value was the one Jaycar had in their catalogue for this particular LED at 9v. I am currently playing around with different 555 Timer circuits, it's been over 10 years since I was a technician. Porta-loo's are not my design. Bought them off a New Zealand auction site as the owner is breaking up his christmas LEGO display. Quote
