There is a standard for the European Union, but it is in the medium voltage standards, which I am not acquianted with. The requirements would of course depend on any coating or wire insulation, humdity, condensation, contamination, finger guarding, earthing, labeling, etcetera.

A great deal of paranoia has come out of any relationship between 60Hz magnetic fields and cancer. In the 1950s fields in this range (15-75Hz, 20-200mG) have been used quite successfully to speed the bone healing process, without any documented cancerous side effects. What has been observed in...

I would use a cheap 3X step-up RF transformer into a generic 3.3V schmidt trigger. It is simple, low power, low impedance, and very robust.

A No.6 carbon zinc cell has enough milliamp-hour capacity to stop hundrends of human hearts, so what is most important is the actual proximity to the heart and the spacing and voltage on any exposed terminals. This is why implantable electronics are so stringently controlled. Most safety...

Ryan, Every industry uses slightly different jargon for the devices they use, even though those devices are common accross many disciplines. I have changed disciplines many times in my 25 years as an instrumentation engineer, and I have found that making up a list of proposed reference...

You have a lot of things to work out before you can measure. You talk about a vacuum. How much of a vacuum? What are the residual gases? What is the allowable composition of residual gases? You are likely to be looking at an ionisation flow meter. What ions are allowable in your residual gas...

It does work, but only for short hops, and the FCC hasn't yet licensed the technology, because it does have some spread spectrum radiation (low band). For more info, visit: http://ambientcorp.com

Brian G is absolutely right. You don't have to be designing circuits for the military to be aware of the hazards of a sucessful "sample test" like a previous poster did for one week. His LEDs probably had a parasitic reverse bleed current protecting them, but unless the manufacturer tells you...

There are a few LED makers who have not only integrated a series resistor in with the LED, but also a high voltage blocking diode, and they have done this so cheaply as to make the added cost less than a 10% adder. At the moment I can't recall who they are, but they were all together in a major...

An old textbook (which I am currently looking for) claimed that 8 milliamps DC can stop the human heart. It also claimed that a pulse of 100 millijoules could also do the job. When a current is injected through the epidermis, no matter how close to the heart, a small fraction of the total...

The other method is to design a series snubber network to put accross the contacts. The time constant of the network is easily settable to provide a slow enough risetime to prevent arching as the contacts swing away from each other, and of course the resistance and capacitance should not pulse...
