* The aim of this project was to create a USB programmer for AT89C2051/4051 Atmel microcontrollers. The device is designed to flash memory chips describe a loaded and can be verified, the error upload new programs.
* For the USB programmer are two Windows applications for the upload control. and a console application for the automatic flash eg directly from an editor out
* The Atmel AT89C5131 controller is the heart of the USB programmer dar. It contains a micro program, which the entire USB communication and the process of flash chips inserted controls.
* Since the circuit is relatively low power requirements, is the direct power supply voltage from the USB bus, so no additional power supply is required.
* There are both Intel hex files, and complete memory dumps (binaries).

TDA2004 4X20W Car Amplifier Circuit
Car amp circuit can be used for a quality used 4 tda2004 tda2004 stereo integrated amp that can provide 2 × 10 watts of power with an integrated bridge mono 20w power connection can be taken. Because it is the only source of supply voltage 12 volts from the battery supply can run with.
In addition to input 12v 2200uf 25v capacitor series addressed 2 of the coil in a relay output if you use the speaker delay circuit is more efficient.
