Mosquito Repellant
I find Mosquito Repellant circuit from Graham Maynard.
Consisting of a phase locked loop (CMOS 4047) wired as a 22KHz oscillator,
The output is further amplified by a pair of complimentary output transistors and drives 3.25 inch Piezo.

Elliot Sound Project
http://sound.westhost.com/
Rod Elliot Sound Project, many scheme here, go visit his page.
i copy this link to my blog for personal use only. i will re-design it to fit in my tinybox. the art of electronic is drawing the PCB :-).
so Do It Yourself, buy the parts, heat with ironsolder, and enjoy electronic hobby...

4 LED VU meter LM324
Get Inspire from circuit-electronic.blogspot.com by Tom.
thanks provide us scheme electronic circuits. I want make cheaper, small and humble Audio LED VU Meter. I think that scheme is simple.
I bought IC LM324 only 1500rp (if 1USD=10.000rp so it's 0,15 USD ?)
