Edit: This is not such a good idea after. Please read why. A EE sent me an email with a great idea! Put the DMM or just everything inside an Aluminum metalized bag --> http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=SCP162-ND These bag have a thin metal layer that makes the mage semitraspent. ...

Here's the hot setup. Outline --> Electrometer, batteries, and diodes to be tested are inside metal chassis. Electrometer is always off except for while measuring diode DC voltages. Electrometer output goes to *very* thin twisted copper enamel coated wire, which goes through a very small chassis pin hole. ...

Building a simple inexpensive 1N4148WS diode array to prove for yourself that diodes produce a DC voltage: It should not take that many 1N4148WS diodes in-series to produce 1 mV. By my calculations, it would take ~ just 17 of the 1N4148WS undisturbed diodes connected in-series to produce 1 mV. The price of the ...

The relatives finally left. I'm a bit sluggest lately, and will not spend much time on the new diode setup over the next few days, and will work on my other project that has nothing to do with research. Here's a updated list of my shopping cart. If anyone has a diode recommendation they would like tested then please ...

I know for fact that the passive component, the diode, produces a measurable DC voltage when left undisturbed inside metal shielding for a sufficient period of time. At the time of this writing, here is my recommendation --> The circuit is very simple. Leave the gain resistor pins (pins 1 and 16) open to provide a ...

Edit: Note, this design is now out of date, and has been replaced with New diode testing design. One nice diode testing methods uses mechanical tilt switches (do not use Mercury switches, as their resistance is too low), that offers no measurable effect on the diode and the measured DC voltage. Such switches are $1.89 ...

Very Important tips on how to replicate the LED experiments. The diode is not as an Alkaline battery. The DC voltage produced by diodes is believed to be from purely *random* ambient thermal noise that always exists in all matter; e.g., at room temperatures there’s over 1 billion joules per m^3 in solids. ...

The most important step: Use ****Undisturbed**** diodes! Be certain to store the LED's in a pitch dark closed metal container for *at least three weeks* before using such LED's for the experiments! Use clean rubber gloves to handle all parts. Even a small amount of residue will significantly decrease the LED's ...
