Mr.Clean's Device

Mr. Clean,

Do you run your oscillator circuit from a 9 Volt battery?
What is the value on the resistor connected to the base of transistor BFY51?
Is your 3 Watt LED lamp a 12 Volt lamp?

GL.

I can give you a little info on your last question.  I mentioned to mr. clean that the LED lamp he shows in video looks like the ones that are either 12 VDC or 120 VAC and that nearly everything I've seen in those type of packages will all have a step down circuit of some sort inside them.  His reply was a confirmation that it was one of those two types but he didn't mention which one.  I brought it up to him because they are not a direct diode type load and it may be important to know what type of actual load was being put in the circuit there.   So far the diagrams being drawn just show an LED (diode) but I'm sure it's going into some step down circuit before it goes to the LED.  Most LED driver circuits regulate both voltage and current and have an IC chip or three, inductor, caps and resistors so it's not just a simple diode across the output.

@KEHY077,

What's the permeability rating on those C cores? Mr. Clean's ferrite toroids are close to 4000. Anything less then that may fail to work. Some guy tried welding rods and failed for that reason.

@syncrho1,
Remember that thane heins used laminates from ordinary trafos on his prototype, but using High permeability cores would be best.

I will have to back and check but I believe the perm. on the 3.5" toroids we used on the Jeanna's circuit was around 10,000.  I still have some around.

10,000 wow, thats great news.  I still have 4 of those!

@syncrho1,

What kind of ordinary transformers? Silicon steel laminations have a much higher permeability then iron. Just briefly; Metglass toroids are a lamination as well. A rolled up strip. Laminations decrease eddy currents in any magnetic core material. This helps the material demagnatize from the induced electromagnetic field. 4000u is not that great compared to Metglass at 1,000,000u. This is a measure of frequency. How fast can the core magnatize and then return to it's demagnatized state per second. At 2200u it's about half the rate. Mr. Clean has an operating frequency that is around 30khz. Half the frequency will transform half the power. Those C cores are only capable of transforming around half the power of Mr. Clean's ferrite toroids. Without knowing exactly what kind of material Thane Hein's laminations are made from, it's not safe to assume anything. Where's it say they're not Mu-metal? You're right that the higher the permeability, the better the magnetic transformer core. Thane's transformer laminations could easily be made from metglass strips with the highest possible permeability. This would be my guess over soft iron.
