Others
Early this year I found two little speakers, and I planned to make a little guitar amp with them.
Today I searched some other little parts (for example switch, LED), and I started to make the "amp".
The basis and the most expensive part is a TDA7052 integrated circuit. I found many wiring diagrams on the internet, which show how to make a mini amp with this IC. I used one of them (a little modified) to create my amp.
The basis of the amp is a 9 x 9 cm based, 12,5 cm tall paper box. I did not use the above mentioned two little speakers, I used an approx. 56 mm diameter 8 Ohm 0.5 Watt little speaker. I used a 220 and a 10 microfarad capacitor and a 22 k ohm resistor. First I fitted a 3 way switch on it, than I replaced it with a 2 way switch. I used an orange LED from an old computer, which shows if it is switched on. The whole cost was about 1000 Ft (4 US Dollars, 3.2 Euro).
And what about the sound? It's pretty good! I try to upload some audio sample in some days!
