A battery puts out DC, it does not provide "half of a sine wave."

An LED dynamo light would be rectifying the AC into DC, though there are >> ways around this if the light has multiple LEDs (two LEDs each
conducting for half the cycle). If there is only a single LED it can
still be powered by the AC from the dynamo but it would be wasteful as
it would only be lit for half the cycle.

For an inexpensive LED light I wouldn't spend too much time trying to
repair it. If it were a high-end, LED light then that would be a
different story.

I also have a cheap dynamo light on one bike, the Planet Bike Blaze
dynamo, the only dynamo light that I'm aware of that has a flash mode.
It has a switch that I never use, it's always on flash mode, and it's
powered by a hub dynamo. At night I have a more powerful light of course.

Stop trying to explain things to someone who doesn't have the concepts. The Problem wikth simply using two reversed LED's is that dynamos increase their ACV with speed. if you simply cut the tops off of the waves if they havemore than the forwaed

bias most of the time. But that throws away a lot of energy. And the chopper would have to be able to get rid of a lot of heat. I can think of some nice ways to increase performance but Frank is in no position to design PC boards. And Flunky thinks that
wave sooldering leaves voids so he is so far out of it that it proves my previous impressions.

And, As usual....

And yes, that article is about voids in surface mount reflow systems.

Besides that, you dumbass, I didn't mention voids. I mentioned cold
solder - different than a void. That you obviously don't know the
difference speaks even more to your overall ineptitude.

One of the reasons I was worth so much money was because I knew every step of manufacturing and could not only design and progam but analyze every procedure from assembly to end product and even packaging and shipping.

And yet you never had to deal with the FDA when designing medical equipment....lol

I never had to deal with the FDA because it wasn't necesary for a machine, not being a food or a drug. While heart regulators are required to meet FDA standards - lawyers delt with tyhat. But explain why a rectal thermometer - your favorite toy - would
need FDA approval beyond the initial calibration of the production equipment?
