The easy way to power your projects Here is the circuit diagram of regulated power supply. It is a small power supply that provides a regulated voltage, adjustable between 1.5 and 35 volts at 1 ampere. This circuit is ready to use, you just need to add a suitable transformer. This circuit is thermal overload [...]

This Solar-Battery regulator allows solar cell arrays to be connected to either conventional lead-acid, sealed lead-acid, or lithium storage batteries without fear of overcharging. It allows two different electrical loads to be driven from the batteries at two different charge states to maximise power usage efficiency. The existing power control circuit in this fridge aims [...]
This simple inverter. The main aim of this circuit is to provide a suitable supply for all kind of low power battery chargers that normally connect to the mains such as mobile phones, electric shavers, etc, even an electronic neon light rated at 5W was successfully connected. Only easily obtainable components are used. http://www.circuits-lab.com/
When experimenting with tube amplifiers, you ability be abashed about the altered modes of operation, like triode or pentode mode. To accord a little advice i developed this PCB. You can body baby Amplifiers based on 6P14/6BQ5/EL84 easily, and the achievement Power of 2..6 Watts is added than abundant for home use. With this PCB [...]
The stoboscope tube needs about 250-400V DC to operate. This high voltage is generated using simple voltage step up circuit built from transistors Q1,Q2 and transformer T1. This circuit gives out about 230V AC voltage which is then rectified with rectifying bridge U1 (must have at least 400V voltage rating) and stored to the main [...]
