The LM317T Voltage Regulator integrated circuit is very useful in many renewable energy applications. LM317T can be used to regulate current – to regulate the current in a string of LEDs – or it can be used to provide a stable fixed voltage output. The LM317T is a adjustable 3 terminal positive voltage regulator capable [...]

This 12V inverter is very easy to build, cheap components that many electronics hobbyists may even already have. Though it is possible to build a more powerful circuit, the complexity caused by the very heavy currents to be handled on the low-voltage side leads to circuits. The circuit diagram of 12v inverter is easy to [...]
The 4-band cipher is acclimated for appearance low attention resistors with 5%, 10% and 20% tolerances. Identifying the amount will become accessible with a little practice, as there are alone a few simple rules to remember: * The aboriginal two bands represent the best cogent digits of the attrition value. Colors are assigned to all [...]
Astonishing effect 4.5V supply This circuit operates a LED in pulsing mode, i.e. the LED goes from off state, lights up gradually, then dims gradually, etc. This operation mode is obtained by a triangular wave generator formed by two op-amps contained in a very cheap 8 pin DIL case IC. Q1 ensures current buffering, in [...]
Zener Controlled Transistor Voltage Regulators By john The efficiency of Zener regulated power supply becomes very low when the load current is high. Under such conditions a Zener controlled transistor is always used for maintaining output voltage constant. Basically there are two types of Zener controlled transistor voltage regulators. They are Series Voltage Regulators Shunt [...]
