@all

There has been a question about the number 1 shown by the meter.
When the meter reach the maximum voltage of any range it let you now that by showing a number one. My first circuit used to give out about 1200volts shown on the meter screen and then showed the number 1 indicating that the voltage was higher than the 1000v range.

It does not damage the meter.

@ Jesus:

Thank you.  I think mine showed about 800 before getting the 1's.  My highest setting is 600 so I guess that is why it did that.  Good to know I did not hurt my meter.  I use it all the time.

ok im impressed bill lol 

when is some one gonna try and CHARGE A BATTERY  SO YOU ALL CAN HAVE OU 


LOL

2 tests charge with hv rectified via  a 1n4007 diode ....

and carge with out a diode

try a car battery 

i hear deep cycle just love rf / re ..... 

ist

to hook 2 jt's togather i would make 2 almost the same    1 npn 1 pnp  and i might try reversing the wind...

found a great vid lol   http://www.youtube.com/watch?v=er4F4BIUAfY

to do that...

Well Bill,

I think you should take at least one of those 100 led light strings and start it up with this flash pack and use it in your bathroom. (Of course, you should remember to read the voltage on the battery before you begin.) See how long they will last on one battery.

And, see if you need the cfl or if 100 led's is enough. I predict you can even read a magazine with it. I can't read with my 35 blue-covered ones. Maybe you will need white covers instead of multicolored.

I want to see if this is already practical. I think it  is. [that is if I understand what you are using]

If one could use one flash pack and one battery and get light at points in a room, there will be no need for lights. Just where you are reading and need to read. Now, how long before the battery goes down.

My led candles use AAA NiMH rechargables and go for weeks, with this a daily or weekly solar recharge could be enough, I hope.

This is so wonderful.
