High Voltage Experimenters Handbook

“This page serves as a repository for all the bits and pieces I am collecting towards creating a modern version of the classic 1954 work by Craggs and Meek: High Voltage Laboratory Technique.” – Jim

High Voltage Experimenter’s Handbook

delabs Notes –

First note a important point, HV is dangerous and the behavior of HV is shockingly unpredictable.

Jim shown caged by Faraday but protected by the law of Gauss. Two medium sized Tesla coils from Brian Basura and Ross Overton were used .

High Voltage Experimenters Handbook

Humidity, clothing, footwear, gloves and furniture all add to the safety factors. Not to mention the special insulators and probes in plastic and ceramic that guards your body from a fatal mishap.

First you should be very capable in using normal electrical equipment with proper prior training. Then you should have experience in Mains power and energy systems. Lastly you should be above 20 Yrs of age and Learn HV theory and Practice under a Very experienced professional in that Specialization. Jim Lux has created some valuable pages on HV.

There is no harm whatsoever now in studying and mastering the theory and also teaching others about the energy that is in high voltage. HV in HF is even more funny.

All that can be invented is already invented by nature. Man can only uncover a few facts and write about it. Start with this handbook. Life is precious, take care.

SpecScope from NFX Development

This is an interesting attempt in the right direction. The bandwidth may be only the audio range, but the first instruments with touch interface for tablets are being built for tablets even by DIY Enthusiasts.

SpecScope from NFX Development

SpecScope is a spectrum analyzer and is the second in the line of engineer applications from NFX Development. The SpecScope incorporates the speed and ease of use to access FFT frequency measurements in a hurry.

Some of the Features

  • Logarithmic/Linear measurements
  • Pinch to zoom in both X and Y axis
  • Selectable No. bin for accuracy versus speed
  • Three settings of spectrum averaging
  • Threshold trigger to hold the peak value
  • Tap to pause and resume measurements (graph is still navigational in this mode)
  • A adjustable sample rate allow analysis from 10 Hz to 22KHz
