I feel like Frankenstein trying to resurrect this cell... It was just sitting here with the multimeter shorted on the uA readings for many hours and it was still hanging (on short) at around 120 uA, so I gave it a quick spray of water and it climbed up to about 1/2 mA, which is almost usable. Then I sprinkled about 5 pinches of alum on top and watched. It was over 2 mA for a while and after about 15 minutes is still over 1 mA. I am not sure why I think the blow torch would help... maybe I just want to burn this bastard to death, but I'll let it RIP tonight and see how it's doing tomorrow. I have a nice wooden frame, 44" of mag strip and some copper wire invested in this bastard, so I won't let it die easily! lol - Frankenstein lives! Either that, or I will burn it to it's FINAL death with the blow torch... we'll see...

    Kill the mod* fu$#($&#, kill it!!!


Die you bastard, burn in helllllll..   


There is a video o mine that I say the same thing , that I made the cells to just kill them at all costs. Paradoxical.


Fausto.

Similar to #354, but thinned out the electrolyte (it a liquid instead of a mush) and poured into cell with a little air pocket and sealed with caulk. Very weak to start. 940 mV under load.

Currently reading 840 mV under load - up a little...

It's up again this morning to 851 mV. My hygrometer is still showing LL - less than 15% humidity. The temp is about the same. This is a moody little cell.

Current mV reading under load - 1081

Today's mV reading under load - 1074

Built a JT like the others. On load, it's reading 1.21 volts. It's bright light like the last 2.

Today - 1101 mV under load.

I need to learn how to build those JT's like you do. Fausto.

Do you have a soldering iron and some solder? You can get these and everything else you need on eBay for cheap. Get a resistor collection (500+<$5), some 100 uf electrolytic caps (100<$10), an assortment of inductors (100<$5), some transistors (2n2222's are about $2 per 100), and some bread boards (about $3 per 10, which you can cut into 4 - 1 will give you 4 of these JT's)... Let me know if you need any help. -teo

I have all that, but when I want to create a JT for the cell I have no idea how to change the values. I can build one based on your design you posted but changing is the difficult thing.

Any values will work to some extent... for higher powered cells, use about a 10/1 for the inductors - base/collector - same basic design. For low powered cells, like 1/2 mA, use 2/1 or 1/1, but use higher inductance, like my 10 mH/10 mH config. I like the 100 uF caps for this because they work well with the blinker configurations I build (which requires another polarized cap across the inputs, like the one I sent you), but you can use smaller capacitance too, like 10 uF, 1 uF, 0.1 uF, etc., and they don't have to be polarized caps. Get a little breadboard and experiment with the values, then when you find something that works best, solder it together.

I am currently out of the inductors I was using for my regular configuration, so I will build them with different values - for a 2 mA - 4 mA draw, I like 4/1, so I may do something like 1 mH and 220 uH... I have a bunch of 100 mH's and 10 mH's too I might play with for the next batch. I have a crapload of hand wound bifilars I use for testing, but at this point, I am just plugging and playing with these little ones. There is a advantage to using bifilars or hand wound coils, but only for larger loads. It's too bad too... I have 3,000+ feet of 30 AWG wire sitting here along with a bunch of cores waiting for me to begin winding again! lol - I love winding my own coils!
