I have been build my own simple charger for my battery grabs from my motor bike. The Battery is Yuasa MF 12 Volt 3.5AH that mean for 1 hour can supply current 3.5 Ampere 12 volt.
The main circuit is:
Circuit in picture
Componen: Transformator 10A 20volt AC be directed made Direct Current by diode 10A, Ampere meter, Volt meter and 12V/25watt bulb then connection to my battery.
The principle of charger is suply must high voltage then voltage of accu voltage. The bulb function is for voltage compensation and current flow control. For better charger circuit the must have capacitor at diode rectifier. Electronics Capacitor...

Is easy build parking alarm system, just using ATmega8, sensor ping and Piezzo.
The circuit PING SENSOR:
* +V connection of the PING))) attached to +5V
* GND connection of the PING))) attached to ground
* SIG connection of the PING))) attached to Pin 13 Atmega8
The circuit Piezo:
* attached to pin 15 atmega8
* attached to ground
This parking alarm will be generating alarm sound if the car closed to any object less than 25 cm.
Here the firmware you can copy and save it in notepad save as parkingalarm.hex then upload to your atmega8.
