:( This was my first attempt on a homebrew electronics :wink:
I built the circut as outlined in part one, for another project I was working on. The only changes I made were a) 9Volts b) a Potentiometer(instead of the 47K resistor) c) inctalled a buzzer(3Volts @ 20mA) on the first pulse(on a transistor) I recalculated the led resistor to 330Ohms and a 470Ohm on the buzzer. I have been unable to get the leds to sequence. Have had several problems learning about capasitors and pots. and I hve a question about caps. will a Tantalum cap. work it is much smaller that the electrolyte one you pictured?(I've already learned that non polarized caps wont work :lol: )
here is a sketch of what I did, it's a model rocket launcher, so disreguard the 2 switches at the front of the sketch. Image

p.s. Where can I find a free Finnish-English translator? it will really help follow the forums.

Love the site Keep up the good work[/img]
