Undervolting is a handy technique to make your CPU cooler and more silent than in its stock configuration. Instead of overclocking your AMD CPU, the idea is to intelligently adjust the voltage-frequency curve of the processor to achieve the same performance at a lower voltage and temperature. ...
The head-end power unit (HEP) consists of another big diesel engine, which itself can make 3,000-4,000 horsepower. It tends to spin even slower than the main engine, maxing out at about 1,000 rpm. The engine drives a generator that provides 480-volt, 3-phase AC power for the rest...
To make a homemade home inverter, you first need to prepare the skeleton, wires, magnetic core, circuit board and necessary electronic components. The skeleton is used to support and hold the windings, the wires are used to wind the high and low voltage windings, and the magnetic core is ...
I sawthis instructableon how to make a high voltage power supply with a CFL ballast circuit and and a long time after that it hit me, instead of breaking all my parents light bulbs why not use an electronic ballast? So I tried it and I was blown away by the results for, what woul...
We're feeding it with 12 volts from power supply here, and it's delivering 1 volt up into a load box. Now when measuring stability, it's important that you make measurements at all different operating conditions that you can expect. ...
1: Wind Power to Electricity You might have seen giant wind turbines spinning on hilltops. Well, with this experiment, you can make your own model turbine to try generating electricity from wind. Start with a 1.5 volt direct current motor. These battery-powered motors are available from hobb...
Going to higher power At the other end of the power-handling range is the EPC2302, a GaN FET featuring a 100 volt/101 A rating and just 1.8 mΩ RDS(ON) maximum. It is well-suited to high-frequency DC-DC applications from 40 to 60 volts and 48 volt BLDC motor drives. In contrast...
In fact, you can easily create your own intercom system using two telephones, a 9-volt battery (or some other simple power supply) and a 300-ohm resistor that you can get for cheap. You can wire it up like this: Your connection to the phone company consists of two copper wires. ...
Convert a 12 volt AC to 24 volt AC by simply plugging the transformer to the 12 volt device. Switch from 12 volt AC to 24 volt DC. To do this, plug the step up transformer directly to the 12 volt device and then use a rectifier bridge to make the current flow as DC. ...
When charging batteries in parallel, where different ratios of charge are to be expected, it is best to make provisions to assure that the currents will not vary too much between batteries. BATTERY TEMPERATURE COMPENSATION Power Sonic sealed lead acid batteries perform well both at low and high...
