LED Current Regulator by Andrew R. Morris

Here is a circuit that will allow LED's to glow at a constant brightness throughout battery life or varying power supply voltage. This circuits is capable of saturating, allowing the battery voltage to get within 0. 3 volts of the LED voltage before the LEDs start to dim. This is far superior to just using a current limiting resistor. Circuit designed by Andrew R.

A Hiqh Quality Headphone Amplifier Circuit

DescriptionSome lovers of High Fidelity headphone listening prefer the use of battery powered headphone amplifiers, not only for portable units but also for home ?table? applications. This design is intended to fulfill their needs. An improved output driving capability is gained by making this a push-pull Class-B arrangement. Output power can reach 100mW RMS into a 16 Ohm load at 6V supply with low standing and mean current consumption, allowing long battery duration. Circuit Diagram

555 Circuits II - Jose Pino's Projects and Tidbits.555 Circuits II - Jose Pino's Projects and Tidbits.

This circuit can be used to activate a relay for two or three minutes. Pressing the switch the relay will be activated. Changing the 1M resistor with a variable resistor you can vary the time. The 0.01 capacitor is important because it prevents any false triggering. The circuit will work OK with 6 Volts without any modification. If you want to use 9 or 12 Volts, you need to change the relay with a 9V or 12V relay. Using this circuit with 120 VAC is not recommended, however, using the right parts.......

Schematics of delabs: Digital 5V Power Supply using L296Schematics of delabs: Digital 5V Power Supply using L296

This circuit is derived from an application note of L296, It is a Power Switching Regulator from ST. The advantage of using a switching regulator is that there is not much Heat Dissipation in this circuit.
