very cool I really liked it!! how about making an FM TRANSMITTER for music played on an mp3 player!! just trying to get away from paying about $50 dlls for a device that I am pretty sure its easy to do!!
The negative output is derived from two sources. The NPN for the positive wave cycles, and the PNP for the negative wave cycles. Since the sum of these two is an ac voltage, a decoupling cap is needed AND it's on the negative side of the circuit therefore it's negative lead goes to ground, and the positive to the load.
My grandma doesn't want to pay $3000 for a new pair of hearing aids so I'm using this a pair of those jelly ear buds this project and a clip on microphone, thank you so much!
Very nice...people needs that...i will put your link in the diy audio forum ....people do not say..but they need this kind os stuff you're doing...teaching the very basic things for them..... great that..... congratulations!
Ok. I'm confused. Do your transistors have an odd pinout. It appears your transitors are CBE (left to right) pinout? At 4:45 I can see you have what should be the E of the pre-amp NPN tied to the B of the 3906 (via red jumper) but that's not in your schematic?
Nice project. Good idea with the printed schematic and marking the wires. For more complex projects, I do sometimes a board in Eagle, because then you can move it around for good connections and part placements, and then solder it on a veroboard. The board layout in Eagle tells me about the positions of IC pins as well, so I don't have to look always in the datasheet while soldering.
Love the video can you do something on how to use 3.5mm audio jacks and 1/4" audio jacks i love to screw around with audio but difficult with out the proper knowledge and you may also know me as insaneinventor88 from ustream

very nice tutorial. what is the reason of using 47uF capacitor in reverse polarity?

@nyuszifuben23 It's by "Garmisch" and it's called "U Fine". You can find it on free music archive dot org.
