Single circuits generate nuclear reactions

[Inventor81]

@AbbaRue ,
Beta rays will not penetrate cases around diodes so they will not get to the PN junction to generate current.

Diode has no voltage across it.

Carbon resistor in shrink tubing (white), two magnets on outside of resistor (so they're isolated thermally and electrically) 2.5mm neo's inside another hank of heat shrink, pink.

1K ohm resistor, 9V battery, direct DC connection, no pulses. Flip the switch, and less than 2 seconds later, diode heats up so hot it burned the crap out of my finger.

Get this: the diode is connected from one of the resistor terminals (negative side) to the aluminum C-shaped tube I bent. No toroid in this test.

I performed continuity/resistance checks on the entire circuit, and checked continuity with the diode connected and disconnected. The aluminum isn't shorting to anything.

OMG
How is a DC signal inducing a current through the diode?

WTF
How is the limited beta I should be getting with 9-10mA current heating up a pn junction?

BBQ Sauce!

carbon film radio shack resistor.

if you speak another language, try english, but feel free to post in german, greek, spanish, or dansk.

it's 5:00 in the morning here, so not doing the PM thing, but here you go... will reply later when I'm conscious.

magnets were placed on either side of the resistor, n-s (resistor) n-s

then shrink tubing to insulate between resistor and magnets, and on outside of magnets to keep them from sticking to other nearby objects.

magnets not shown on schematic, but you get the idea.

switch was a spst slide switch.

Duracell 9V battery.

Finger got warm when placed within enclosure, lost track of switch position, could determine if current was flowing based on temperature of finger.

weird.

Hi,

Could you measure the current taken from the 9V Duracell from the moment you switch on the spst?  This way you can surely close out an unseen temperary connection between diode's anode and battery+, bypassing the 1kOhm?
Sorry for saying this but you have to close out this possibility....

It even did it when the end of the fricking diode lead was just sticking up in the air, not touching anything.

when I say there was NO voltage across the diode, there was NO voltage across the diode. I checked and re-checked it three times since I posted the photo originally.

No continuity in the circuit until the switch is closed, resistance of circuit is 980 or so ohms. 989. fluctuates a little bit due to el-crapo 3 dollar meter.

NO voltage across diode.

Diode also checks out as good with built in diode tester.

No clue what's going on.

Also, not sure how 9mW would warm my hand unless it was beta that was being focused by C shaped aluminum housing.

Checked continuity between all parts of circuit (resistor, diode (when free standing), circuit board contacts, power, ground, and switch terminals) and the aluminum shield.

NO continuity. Shield is floating electrically, and sits only on insulated PC board. on other side of board is a patch of epoxy that was holding on battery clip from a previous project. recycled PC board. no shorts anywhere on board, since I used a previously unused section of the PC board. Its a DIP breakout board from radio shack.

The alligator clip and hex nut you see in the lower right corner are also electrically insulated - just needed to bend a tab and clamp it on so the shield didn't shift around and short out on the toroid that I was going to install.

Totally weird crap, and I'm going to sleep.

Someone else replicate?

anyone have carbon comp. resistors instead of carbon film? give it a shot?

just some tape, magnets on the resistor, and a diode, and a piece of aluminum foil near the diode. No clue. Try it. Burn your finger.

Join the club!

Have you tried bending out the body of the diode gradually from the supposed "focusing" area of the aluminium housing? If the heat developed starts reducing, then the clue indeed should be from radiation coming from the resistor...   
Maybe would be a good thing you could include the radio shack # for the resistor for those wishing to rebuild.
I happen to have metal layer resistors at the moment.
thanks, Gyula
