    'Water Cooling System: Can it Cool my Computer?

    Hi! I'm hoping to get the water to move at roughly 0.1kg/s by using this pump: http://www.overclockers.co.uk/showproduct.php?prodid=WC-103-EK It's rated for 400 litres per hour (max), so a bit over 0.1 kg/s. Do you think I should have more water with the water moving at that speed...

    'Water Cooling System: Can it Cool my Computer?

    Hi! I am trying to design a water cooling system that could cool down my computer from 100C to about 40C, with 600W of energy being provided by the components. Could a system that moves 0.2l of water at 0.1kg/s from a water tank to the computer components to a radiator and from there back to...

    Building Faraday Flashlight: Stepping Up Voltage

    Hi! I'm building a Faraday flashlight and when I test my generator I'm getting about 200mA at 0.5V. The LED that I'm using is rated at 3V and the capacitor at 5.5V. After 60 seconds of shaking the capacitor only had about 150mA at 0.5v stored, so the LED didn't light. Does anyone have any...
