It is recommended to Have a "Fuse" in the Power Line and to always have a "Load connected", while power is being applied.
The Fuse should be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output.
Build your own Accurate LC Meter (Capacitance Inductance Meter) and start making your own coils and inductors. 1Hz - 2MHz XR2206 Function Generator produces high quality sine, square and triangle waveforms of high-stability and accuracy. Having the ability to control various appliances inside or outside of your house wirelessly is a huge convenience, and can make your life much easier and fun. Presented here is a circuit for 30V 10A variable bench power supply that offers variable voltage and current adjustment. Check with a multimeter set to resistance and measure between collector and emitter terminals. I've recently heard from Ryan Laurenciana in the Philippines who has built himself a 12V 30A power supply. Below are some pictures from Aamer Reza who built his 12V 30Amp power supply and added water cooling. Pedal Powered Biodiesel Pump (Methoxide Agitation and Transfer): PPPM I, directly powering Hypro 4 roller pump. For efficiency a voltage multiplier should be powered from a source that is already a relatively high voltage. For safety and improved performance the voltage multiplier should be placed in a protective casing, such as a PVC pipe filled with oil.
Example ExperimentsA homemade voltage multiplier is perfect for powering an EHD thruster (aka Lifter). Comments and questions for DIY Voltage MultiplierThe information provided here can not be guaranteed as accurate or correct. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.


The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.
It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.
BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. It's breadboard compatible so it can be plugged into a breadboard for quick prototyping, and it has VCC & GND power pins available on both sides of PCB.
A test with the output leads shorted together will soon show max current settable range. A suitable transformer for the amps required will be needed.
The half wave method is the easiest as it requires fewer components, but a full wave circuit will perform better. The image on the left shows two protruding screws used for the AC input connection, and he other image shows polished coin used for the high voltage output. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery. It's small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of. It is a simple circuit with a hand full of components. The only need for a pcb is for the LM723 and the 3 small resistors and 2 caps.


Many lighting devices contain inverters for powering vacuum tubes such as, florescent lights, cold cathode lights and plasma globes. If you just want to get one working as soon as possible the the half wave method would be adequate. By using Polymorph to seal the ends of the pipe, it can be filled with oil to prevent corona leakage from the internal connections. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. I have had this circuit in use now for over 20 years and has never let me down and is one of the most handiest gadgets i have built.
These types of devices usually run from 12V DC and can output voltages up to around 20kV AC. A more sturdy method would be to fill the pipe with epoxy resin, but this may be difficult with compact component arrangement. USB IO Board is self-powered by USB port and can provide up to 500mA for electronic projects.
Board features 28-PIN DIP IC socket, user replaceable ATmega328 microcontroller flashed with Arduino bootloader, 16MHz crystal resonator and a reset switch. Arduino sketches are uploaded through any USB-Serial adapter connected to 6-PIN ICSP female header. Board is supplied by 2-5V voltage and may be powered by a battery such as Lithium Ion cell, two AA cells, external power supply or USB power adapter.
