Hi all,

I need help, I'm trying to resize pictures so I can post them here at 50k or less but I'm having problems with keeping the quality (they look bad)  I p.m. JustMe and asked if she/he can tell me how the dune buggy pictures she/he posted looked so good at size 600 x 400 and under 50k  .

Can anyone tell me how to do it.

I do not know what Operating System you are using; if you use MS Windows, you can install the Image Resizer utility located here:

The file download is here:

Thanks Angle,

that works great. will post some pics soon.

However, in all fairness, at 0.01 amps there is now a 50% margin of error - ie. instead of 0.01 amps it could be 1.49 amps... and at the absolute lowest calculable measurement that the machine is capable of, it is more than a little suspect of inaccuracy. Same goes for your resistor... with output as low as you are trying to measure, if you rubbed it in your pocket for a couple of minutes you might scrape off enough atoms woth of resistance to skew the results... try to replicate this with enough elecricity to be accurately measurable... otherwise you might need to spring for the big bucks to get highly accurate meters... either way, I'd hold off on that patent application until you have something with enough value to recoup the cost of the patent... or at least long enough for PB to race to the patent office and file on behalf of the spooks - right PB?

just a little more clarification here - at 3.377 volts you are getting 0.0114 power, so you are figuring 0.0033 amps... that is one third of measurable amperage on your test meter...

Hi All,

I was busy Easter weekend building a new generator to test with four  2" x 1" N50 super neo magnets that I would allow to accelerate to full speed inside a protective box

See pictures below of what is left of that test. No one was hurt thank God, but the whole thing was destroyed, the magnets just broke off the epoxy on the wheel at the speed of about 3,000 RPM and came through the side walls and top. So be careful and don't use Acrylic, Plexiglas or particle board if you build a protective box. Use only 3/4" plywood on all walls and use 1/2" Lexan for see through areas.

I would also suggest not to go over speeds of 2,000 RPM

The ruler in the picture is 15" long.

At the very worst the input power is 0.73649999999999 x 0.01499999999999 = 0.0110474999999924850000000001w (not counting any possibility of the meter being wrong)

And that is still slightly lower than the output power, and let's face it 100% should be impossible.

But yes the resistor and the meters could be wrong but if they are both fine that that looks to be OU, are you still offering 3-1?
It is premature to break out the champagne and no one has suggested otherwise but they are nice looking results.
