Amp with 1554.

Since at the moment I'm on a budget, the easiest way to get some sound is gainclone amps. One of the cheapest and quickest to build would be TDA1554. Its cheap (3-4$, or 12 LT in Lithuania) and requires very few external components.

For the amp you will need:
PCB
Chip (TDA1554)
Some electrolytic capacitors - 2200uf, 47uf, 100uf, 10uf.
Ceramic capacitor - 0.1uf
Resistor - 39kohm
Potentiometer - stereo logarithmic if you want to have sound control on the amp.

Heres the tadasheet for TDA1554: http://www.datasheetcatalog.org/datasheet/philips/TDA1554Q_CNV_2.pdf

Simple schematic (taken from datasheet)

Heres the gif showing the PCB layout:

 

I won't be making it during weekend, but i should be able to make it Monday or Tuesday. Well, good luck to everyone!

  2. "Simple" schematic?

    Man, that stuff looks super confusing.

    Can't wait to see how it turns out, though.

  9. Serious question! I've started dabbling in building amps on schematics (I'm trying to build a noisey cricket amp right now) but I can't seem to get it to work. How knoweldgeable are you on schematics and electronics? Great blog by the way. Please get back to me when you can!

  10. The pcb layout makes me think of tentacle rape. Other than that gl :)

  11. Brandon B - I'm pretty green on theory part, but in these works there's not much of that involved - i could take a quick look at your schematics/made items and see if i can find any mistakes

  12. simple schematic ... wait wha ...
    i guess im just too dumb xD

  20. I dont know about that. Looks too complicated
