My project is a self-powered solar data logger based on microcontroller. Put out in the sunlight, it will measure the light level and log this to memory to be later downloaded to a computer. The system is powered by a small solar panel and battery.

Air Flow Derector PDF Print E-mail
Written by Administrator   
Wednesday, 30 January 2008
This simple circuit uses an incandescent lamp to detect airflow. With the filament exposed to air, a constant current source is used to slightly heat the filament. As it is heated, the resistance increases. As air flows over the filament it cools down, thus lowering it's resistance. A comparator is used to detect this difference and light an LED. With a few changes, the circuit can be connected to a meter or ADC to provide an estimation on the amount of air flow.

0-30 Volts / 2,5A Variable Power Supply PDF Print E-mail
Written by Administrator   
Monday, 28 January 2008
This is a high quality power supply with a continuously variable stabilized output adjustable between 0 and 30VDC. the LM 723 is the heart of the power supply which drives the BD137 and then the 2N3055. The circuit provides short circuit protection. And has great stability at voltage changes. Drive the circuit with 24 Volts 3A from a transformer. the 2N3055 needs a good heat sink.

Support of  process learn to teach at technological era claim all process learn to teach to enter in management of quality Pra-In-Post of  learning process have to be certifiable. Certifiable of  learning process  will be seen by when process start and end it  timely, do not quickly do not be late also. Bell represent the fatal and vital suggestion for the school of. Seen to by trifle, but if duty to sound the bell is not conducted with the high discipline, hence PBM will be annoyed.
