Gonna take a shower but I'll exist proper in about half an hour. But go ahead its easier to read after the fact on my phone.

Actually, I have to run because I need to go home, but I'll be back soon as well.

Kk I'm here when you are

Okay, so, I need to build a circuit board that will blink a series of LEDs without a timer.

I have been given 3 10μF capacitors, I have a variety of resistors, some transistors, and 2V red LEDs and 3.4V white LEDs. (Also some LEDs from Star Trek, but I don't know their V)

And I'll have to run it off of one or two 9V batteries.

I'm worried that the capacitors don't have enough capacitance in order to really work this.

I was looking at something like this: tronixstuff.files.wordpr...

If I run the capacitors parallel, I should be able to get more capacitance, yeah?

What I'm not sure about is how I would go about powering multiple diodes, considering their forward voltage is so different.

And I'm not sure I'd want to run them in a series, considering how small the capacitors are.

Resisters add in series while capacitors add in parallel yes. I can't do the math for you being away like this but look up Ohm's law and

Kirchoff's voltage and current laws. Draw out your circuit and solve for what you need

Woo, I have a textbook now!

\o/ let me know if you need anything. Odds are you won't hurt yourself do go for it :3

I think I simply don't have enough capacitance.

I can get it to work with my breadboard, but the LED is very dim.

At least you know the problem. Use fewer LEDs for the time being or wait till you can buy a bigger capacitor.

I managed to work the transistor and I've got it brighter, but it's not blinking.

mrrr

Oh, I think I figured out what I'm doing wrong, and I'm not sure I can build the circuit I want to on this breadboard.

:c

...except for the fact that I have wires. -___- /dumb

Okay, so it may still be a capacitance problem? I try to charge the capacitor to the transistor, so that it can emit to the diode, and I'm getting nothing.

If I bypass the capacitor, the circuit is fine.

You give the capacitor time to charge?

Yes.

I'm gonna try longer, though.
