Green LED array measurement - RECORD
Today the 6 in-series green LED array, Radio Shack part number 276-009, shattered the record for maximum recorded DC voltage at producing 1.10 volts DC!
Here's the details from past two days of measurements -->
Yesterday 2009/7/30, 5 pm PT, 78 F, 232 mV. This measurement was taken shortly after placing the green LED array inside the Hammond shield connected to the electrometer input. LED's were inside dark room.
Today, 17 hours later as the LED array sat undisturbed inside a thick Hammond metal shield while connected to a low leakage capacitor, 2009/7/31, 10 am PT, 76 F, 1.10 volts
After seeing the 1.10 volts I stared at it in utter amazement for perhaps 10 seconds, but it seemed as eternity. The 1.10 volts was stable. After staring at it, I immediately opened the shield lids, grabbed a flashlight, turned it on, and shined it on the new tilt switches to verify they were making contact. Indeed, they were making contact, and the DC voltage was legit. I knew the flashlight would highly disturb the LEDs even though the light was not directed at the LEDs. Within ~ 5 to 10 seconds later I looked at the voltage meter, which showed the DC voltage dropping at a fast rate as the LEDs became disturbed, as expected.
The diode research is getting exciting! Yesterday, I made some mechanical tilt switches to replace the Mercury tilt switches because even the slightest disturbance decreases the Mercury switch off resistance far to low for such voltage measurements. The new tilt switches are made to have ultra high off resistance. Here's how they were made. An ultra high resistance insulated metal wire, about 1" long, arced 90 degrees, where one end had a small loop that had a short insulated wire dangling from the loop. The other end was soldered to an INA116PA electrometer input pin. The same was done to the other INA116PA input pin. The dangling wires would rotate as the entire setup was rotated. On the other side, separated ~ 1 cm, are two short insulated wires where the wire ends are split to form a V-shape. When the set up is rotated, the dangling wires make contact to the V-shape wires, which is connected to the LED array & low leakage capacitor. Her's a quick drawing of the new tilt switches -->
[edit: I no longer recommend this exact type of homemade tilt switch unless you place an appreciable amount of weight on the hanging wire. After ~ a day a micro layer of oxide forms on the copper, which makes a poor contact. The weight of the short swinging wire is insufficient to make good metal-metal contact. This switch would work if weight was added to the swinging wire. When time permits I'll make a much improved tilt switch. For now, I'm using a *ball* tilt switch that was purchased last year-- part number is unavailable.]
The green and blue parts are electrically insulated metal wires. The black lines show the metal. The red arrows show the direction which the short green wire rotates when the setup is tilted. This allows for great separation distances, which equates to ultra high resistance.
Great care was taken to be certain that when the setup was flat (off) that the LED array was connected to exceptionally high resistance, probably well above 10 Tohm. There was no glue, no tape, or any such material between the LED array output pins. The LED array sits on a thick clean plastic plate. This allows the LED array to become fully undisturbed.
Anyhow, IMO the 6 in-series LED array would probably produce more than 1.10 volts when fully undisturbed, but unfortunately I have no idea how long it's going to take the LEDs to become undisturbed after shining a relatively bright flashlight near them. The LEDs are coated with Liquid Paper on all sides except the bottom, which was facing the flashlight. The light had two affects on the LED array -->
1. It disturbed the LEDs.
2. It caused the LED array resistance to significantly drop, which appreciably discharged the low leakage capacitor.
So the LED array needs time to become undisturbed, and it needs to charge the low leakage capacitor again. Normally I would say this would take at least three weeks, but this will be the first time that extreme care was taken in being certain the diode array is connected to ultra high resistance. This might decrease the diode recovery time.
If twice as many LEDs were placed in series, for a total of 12, it appears they could produce enough DC voltage to charge a 0.01 uF capacitor that could flash an efficient LED enough to be perceived by a person.
One final note, yesterday the entire diode testing setup was moved from the garage to inside in the lab. The reason being is that the garage temperature extremes is significant compared to inside the lab. This is an attempt to minimize diode disturbance. Maybe a sign should be placed near the testing lab, "Shhhh, diodes are present!" :-D
