Circuit Help

Hi, is anyone prepared, or no know of someone who will build circuits for cash? I have the schematics and I will happily provide the components.
There are 2 circuits I need: A flicker circuit using 556 chips, and an 30 LED sequencer, which can be done using cascaded 4017's I think?

Many thanks

for anyone wanting a really cheap way of simulating the rcs thrusters for either the enterprise or a starfury use the following circuit and just change the capacitor to a 4.7uf and the 47K resistor to a 100K preset - so you can slow the whole thing down and get the leds to stay on for longer - not b...

I've had a look at that and it should work, I'm just wondering if I could incorporate a single flash white LED using a 555, to come on just as the red turns off? This is probably a really stupid question but for the benefit of us complete amateurs - the circuit runs off 5V how would I incorporate it...

or you can also use 1.8mm leds and just black out the square base that they sit on.

Photon Torpedo circuit

Hi, I've been searching for sometime now for a cheap circuit that simulates firing a photon torpedo effect. I've looked through the threads and wouldn't be surprised if others people are in the same boat, with round 2's 1/350th re-release. I don't want to go down the PIC's route as I have a basic gr...
