This is a construction log of my sound reactive high speed flash. Essentially it listens for a sharp sound and sets the flash off when it hears it. The entire setup cost me $7.50 because most parts were salvaged from other eTrash.
Why does my new fluorescent light take five minutes to reach it's total brightness? In many countries that are driven to improve their pollutive emissions fluorescent light bulbs have now become the norm. The formerly used tungsten light bulbs
Today i modified a 6x8 inch photo of the Aurora Australis so that the stars flicker in the night sky. The photo frame sits easily on a desk and turns on and off via a switch on the side. A watch battery sits on the back which can be changed if it runs out.
This log involves the design and construction of a canvas print of the Aurora Australis mounted on a pine frame. Fibre optic lights will be placed at most star points and will have a flickering or twinkling effect like normal stars.
As a computer repairman i find myself in possession of way too much electrical equipment and components. I try to put them to use where i can and this log has to be one of my favourites. Millions of tons of e-garbage is continuing to pile up
This log deals with how to reverse engineer a hands free phone kit and turn it into a remote shutter release for the canon 400d and other model digital cameras. You can find these hands free kits for next to nothing and the one
The object of this hack is to remove the laser diode from a DVD burner and transfer it into the casing and driver of a hand held laser pointer. If you attempt this yourself. BE WARNED ... this laser diode is very dangerous and protective eyeware
I have called this circuit the 'Oscilifier' as it is an oscillating circuit that seems to magnify the output of light from a light emitting diode. It uses a bifilar wound air coil in a very simple transistor circuit resembling a joule thief.
Magnesium graphite homemade battery. The human race has come a long way with technology, and in some ways we rely far too much on that technology. This is evident during a power loss when habit kicks in and we still reach for a light
Disposable cameras contain very powerful circuitry that convert 1.5 volts to 300 volts in order to set off the flash. This log shows how to modify the circuit in order to use a double a battery to light up a 10 watt fluorescent bulb.
This is a variation on the Baghdad Battery using only tap water as an electrolyte. Can you run a light, or recharge a small electronic device using only water? Sure!. While copper and zinc have a very good potential voltage difference
A simple explanation of how a plate array in a HHO electrolysis device also acts as a capacitor. When the unit is switched off the plates hold a slowly dissipating charge, and the plates still produce small amounts of gas.
