To build the testing unit you need 5 diodes, one on the wire and 4 more to make a bridge diode.

mmmm
I just hooked up a 4 prong boughten bridge. It has 2 pins + and - and in the middle, a sine wave over the remaining 2 pins.

I hooked the + - to my meter, pushed the battery into the holder and touched one end of the pick up to each of the middle pins.

I got 1.56VDC in 1 direction and 0.8VDC in the other.

Now I can see that something has gone wrong with my coil. for sure.

@mk1,

In a bridge thingy with 4 pins, is there already a diode inside? There must be so they can mark which one is negative???

@Pirate,
I am sorry to say I can't watch it.

That guy is on assignment. Pay no attention. It just puts you in a place where he wants you.
You are a fine human being. Remember that.

@ All:

Another short video here.  This one uses again the ferrite bead to light 3 superbright leds.  Nothing new you have not seen here in photos.  Oh, duh, I found my little cam has a tiny little switch on the side that is for the macro setting!!!!!  The close-ups are now in focus!  This will allow me to film better shots of the Fuji circuit.

@ MK1

Thank you for your support.  I have seen that guy around for a while now.

@ Jeanna:

Sorry you can't see any vids right now but, as you said, better to play it safe for now.  Thank you for what you said, that was very nice of you to say.

Anyway, today I just wanted to get familiar with my little cam and I guess I did that.  Next time I have some time, I will try to make a video of something new.  Of course, I do have to shoot the 400 leds thing but right after that.

Thanks again to all of you for all of your effort put in here and also, for all of your positive attitudes as well.

@ Gadgetmall:

Thank you too for your support on my video attempts.  I really do appreciate it.


Hey, I noticed we have not heard from Jim in a bit.  I hope the mice are not winning the war down there.

hey bill, i was messing about with some of the solar cells i have here. it seems the ones i have are most sensitive to ~880nm. hope that helps with your upcoming project.

@ Wilby:

Thanks.  How did you know this?  Were these marked or did you have some way to measure it?  I don't think the ones I ordered had any specs on this, which would have been nice.  Do we know what the leds are putting out?  I have a lot of stuff to learn and do in a short time it seems.  I am kind of hoping you will tell me there is a simple way to measure this.  Thanks again.
