Yeah man. I want to build more.
I have been trying to trace the signal and figure out whats happening to it as it goes throughout the circuit, but I'm having trouble. The IC boosts the signal? And, then the cap has something to do with the frequency right? And the diodes clip the signal, I believe, but what is the reasoning behind them facing opposite ways?

Hi
Im a real noob myself, but i find reading the datasheets is always useful and can give good info and test circuits.
http://www.biltek.tubitak.gov.tr/gelisi ... /LM386.pdfThe amp has a boost of 20 with pins 8 and 1 disconnected. You can ramp this up to 200 by adding a capacitor between these pins.
Theres other cirtuits in there including a bass boost i might have a look into.
The cap blocks DC - why or how, no idea!
As to the diodes; pass. Ive seen this arrangement before tho.
Cheers for the circuit, amazing
(sorry if its rude to reply to your thread).

This was my first breadboard project ever- and it is still on there- I love it. Have tried all sorts of diodes even rectifier diodes which sounded like shit. I remembered at some point that LEDs are diodes and how fun to pop different ones in and get a light show!! So far an amber/orange clear superbright pair has been my favs. It does not quite like 9.76V I have to dial it back on my test rig sag to like 9V. Also I have tried many different caps and wow, some are AWESOMELY sick and fun- you have to adjust the supply voltage but I want to expand on it somehow or improve on the idea.
Thanks man!

Wow. Gotta check this out in the future.
