Crystal Battery #353 - Day 26 - First Maintenance Cycle
« Reply #270 on: December 21, 2014, 05:49:02 PM »
Interesting how this cell lasted so long before the first maintenance cycle and then came back stronger...
The Build Video: https://www.youtube.com/watch?v=UPi8fkn1qFA

Crystal Battery #353 - Built Nov 25 (white LED - dry build w/Borax)
Nov 26 - 1066 mV - day 1
Nov 27 - 1105 mV - day 2
Nov 28 - 1054 mV - day 3
Nov 29 - 1084 mV - day 4
Dec 1 - 1050 mV - day 6
Dec 13 - 972 mV - day 18
Dec 14 - 903 mV - day 19 - disconnected JTC to create a better connection, then forgot to reconnect it...
Dec 18 - 989 mV - day 23 - reconnected JTC
Dec 21 - 446 mV - day 26 - no light
 - 961 w/no load, 0.8 mA on short, and climbing...
 - 1.01 mA after a few minutes and climbing
 - reached 1.09 mA after a few more minutes and began dropping
 - 890 mV w/no load after short and climbing
 - added 3 mL of water, quickly rised to 1600+ mV w/no load
 - shorted, it started at 19 mA and quickly pegged the meter to over 200 mA
 - set to the mV reading and it was showing over 1700 mV and climbing
 - reconnected JT circuit, 1200+ mV under load, climbing
 - after a few minutes, it is 1270 mV and still climbing under load
 - JT amp draw is 5.9 mA... nice and bright!

That's very impressive.

That's very impressive. Fausto.
I just gave it another test since I know the water is settling. It's bouncing around 1080 mV and 5.3 mA under load.
To give you an idea of how this same circuit performs with standard batteries, I hooked it up to brand spanking new Energizer AA
 - 1608 mV and 9.5 mA under load.
Then I hooked it up to a AA 1.2 V Ni-MH battery... it's about 6 months old, but has never been used... I don't think it is at full power...
 - 1160 mV and 4.7 mA under load.
I think this is a great standard for testing the real power of these cells, which we could ask experimenters to do.
It gives a much truer baseline on the power of these cells than anything I've seen other experimenters do.

Publish that JT in detail so I can build one, please.

It's the one in the care package I sent you, minus the 3F cap...

Just pull the 3F cap, and you have it already built!

Crystal Battery #63 Status - Day 343 w/10 mH JT Circuit
« Reply #277 on: December 22, 2014, 07:24:57 PM »
Here's a little nostalgia before Christmas!
This cell has sat for well over 6 months with no water and still comes back to life.

The first number on the meter (021) was the voltage of the cell WITH load or without load?

That's no load. I was surprised to see anything but zeros....

Marcus Reid - Conference on the Physics, Chemistry and Biology of Water 2014

Fresh:  https://www.youtube.com/watch?v=aGT48R1_P8Y&feature=youtu.be - Fausto.
So... it looks like he likes Mn2O3... it's dangerous for us home experimenters... I like the MnO2 we are using... it's not dangerous and
from what I have read has been used to color skin - pigment...

Marcus seemed a little nervous there, but it is so wonderful to see him out and about and I love that he is moving forward and getting
at least some attention! I am a big fan of his!

Crystal Battery #64 Status - Day 341 w/10 mH JT Circuit

More nostalgia.. these OLD crystal cell's aren't strong, but they show how they can sit around for a long time unused and still come back to life.

This old crystal battery came back to life with a surprising 1.9+ volts!

Crystal Batteries #24-45 Status - Day 372 w/10 mH JT Circuit
« Reply #283 on: December 23, 2014, 01:10:20 AM »
Just clearing out my inventory of old crystal battery experiments... trashing some... putting a few back on the shelf...
This is an interesting 21 cell IBPointless2 build I used to test variations in the builds while trying to make them all the same...

Lessons learned...
#1 - I can't build these things exactly the same... it would take multi-million dollar operation to get something in place like that...
#2 - I CAN work with what I build. A JT circuit and one crystal battery cell works fine for the variations.
#3 - These IBPointless2 cells NEED to be watered to work... I don't care what IBP says! lol
 - I think the video speaks volumes on this last lesson learned...

http://youtu.be/LCJtTmcm64k

The light died after about 10 minutes and was completely dead after 15 minutes... no power with these little bits of electrodes...

Simplified Joule Thief (JT Circuit - aka JTC) For Crystal Batteries
« Reply #284 on: December 23, 2014, 02:17:14 AM »
I've been playing with this for several days now, but it looks like the resistance in these little inductors is the key to keeping things simple.
I like the 1 mH the best, so I have a bunch coming soon! 10 mH don't work with regular AA and AAA batteries... too much power...
Less than 1 mH starts having issues with the brightness of the single LED's I use in the circuit. Let me know if you learn anything on this,
but for the moment, I am done with this and waiting for my inductors....
