Second Stage Joule Thief Circuits

[hartiberlin]

Well, normal supercaps have a limit charge voltage of around 2.7 Volts.
You should not charge them up higher, as they could then go boom. 

With the alufoil-graphite supercaps, you could go still about 0.7 Volts higher,
as the galvanic dissimular metal effect adds 0.7 Volts,
but I would recommend not to charge them up over 2.5 Volts, so the
alufoil will not get destroyed.

Maybe we will still also find a better electrolyte than NaCl saltwater solution.
The solution should also be not too concentrated, otherwise the alufoil
will decompose after a while.

Also it could be much easier to use graphite paper as the graphite
layer, so just use an acryl binder with water to put the graphite powder into
a solid flat paper like shape and already put the pencil graphite rod
into it before drying, so the pencil graphite rod electrical electrode connector
will already be "glued" this
way into the "graphite paper" and must not be fixed later.

But you must roll up then the stack already before the acrylic binder
has dried, otherwise it will be hard to roll the stiff graphite paper later
after it has dried up...

Hope this helps.

yes actually it did give me an idea . Might work might not . I have rolls of aluminum flashing to use and some brown paper bags and bake it in an oven  a graphite mixture on it . Well we will see . mixture is another thing  i can research . there are a few milliliters of highly posionious substance  in My ultralcap i did forget the name in a maxwell ultracap as the electrolyte so maybe there is a substitute for NaCl saltwater .
Have a good day or night  its 1:39 am here .
Also if you celebrate Thanksgiving in Germany . Happy thanks Giving

Stefan:

This sounds like a nice  project.  With all of the smart and inventive minds here there is no telling how far this could be taken.  I look forward to seeing some results over on your topic.  Thanks for telling us this.

warning !!  as hear.. this POWER CAN... has the potencial to go boom.. ... right around the plannet in a big hurry ... 

and i aint talking just blowing the plugg...
