Sound reactive rumble problem
« on: December 18, 2010, 01:54:17 PM »
Hey guys

I just can't get this working.
https://www.acidmods.com/forum/index.php/topic,35291.msg285090.html#msg285090

These are the parts I used:
- 2N2222 H331 transistor
- 220 Ohm 0.25w Carbon 1/4w Resistor 220R
- Silicon Rectifier Diode 1N4001 1A 50V DO-41 RoHS

When I use a rumble motor, the voltage is always 0.47/0.48
When I use a led, the voltage is always 3.45
Even when there's no sound. So it seems that the voltage depends on the "consumer".

Checked the emitor and collector with a DMM, so I'm sure I ain't wiring it wrong. I even used a crocodile clip as heat sink while soldering so the transistor doesn't get damaged due to the heat.

Also tried the other way of Ghost_Death, but then I don't even get any voltage at all.

So I'm guessing I need other transistors? Or could I also do this with an LM386 chip?

Sorry for my bad English btw.
