Second Stage Joule Thief Circuits

[gotoluc]

Hi Gadget and everyone,

interesting where you have taken the Joule Thief

Glad to see Groundloop (Alex) is here and helping as usual.

I did a little research on AA batteries and this is what I have found. A 1.2 volts Rechargeable 2500mAhr battery will give out a total of 3 Watts/Hr and a 1.5 volts 2500mAhr battery will give out a total of 3.75 Watts/Hr.

I'm no math wiz but I can see where you're going with this and I applaud you for the idea and mostly sharing it.

Here are the conversions in Watts/hr of batteries and a 650 Farad Ultracap

2500 mAmps/Hr x 1.2 volts = 3 Watts/Hr

2500 mAmps/Hr x 1.5 volts = 3.75 Watts/Hr

650 Farads at 2.6 Volts = 2197 Joules

2197 Joules = 0.61 Watt/Hr

It would seem that you could charge your 650 Farad Ultracap to a maximum of 5 times with a fully charged 1.2 volt battery before your battery is flat.

I will definitely replicate your experiment as I have some Ultracaps and Nichrome wire on hand.

For anyone interested, here is a good link to convert most every measurement system: http://www.nettam.com/convert.html

Thanks IS

This kind of creative experiment is right up my alley

It will be a pleasure to play with this.

i think the best 1" gm toroide would be a turbine unit ... that speeds up till it rings the output...




or aproches resonance ....  once you get it whipping round and round  you can pulse it ...  and get massive kicks...  and it dont slow down

thease are beond what most can visualize.. 

sure is fun tho..
