Alternative Halogen Power Supply
Alternative Halogen Power Supply
October 3, 2010

Readers who do not care to modify the power supply of an old PC into a suitable halogen power source (see our April 2006 issue), may find the present design a welcome alternative. The circuit... [more]

POT-PLANT POWER
POT-PLANT POWER
October 3, 2010

Following a hunch, the author discovered (or re-discovered?) that all plants carry an electric charge relative to the ground. This charge is more or less constant regardless of the size of the plant - a... [more]

Protection For Voltage Regulators
Protection For Voltage Regulators
September 30, 2010

People often forget that many voltage regulator ICs have an upper limit (usually 35 V) on the input voltage they can handle. That applies primarily to types with a fixed output voltage. Adjustable voltage regulators... [more]

Symmetrical from a single voltage supply
Symmetrical from a single voltage supply
August 4, 2010

Many times we needed symmetric voltage, but we do not have the possibility him of taking immediately, from a existing supply. Then it will be supposed him we create from the existing single. [more]

The power line fluctuations and cut-offs cause damages to electrical appliances connected to the line. [more]

Electronic Fuse for Power Supply
Electronic Fuse for Power Supply
April 24, 2010

The power supply, with electronic stabilisation - mainly those of laboratories - it should they are protected from ‘’over current’’ that emanates from short-circuits, erroneous association or damage of repaired appliance. [more]
