He hits you with a wet phone book....in the face.....with the mother of all nuggets.....find it!


Sweet video TK from the guy who dislikes scopes and proper measurement.....

Thank you for posting the link to my video. I hope people find my videos entertaining and educational and informative.

...if it were ideal again and we used an inductor with say a 0v drop diode, then the transfer would be a complete transfer, the 10v cap would end at 0v and the 0v cap would end at 10v...

Yes, ...or -10V

^{P.S.
At low currents, a MOSFET synchronous rectifier acts almost like a 0V diode.}

I have heard of them and read a little, I would like to try them.  Any special part no you can recommend as The mosfet Im working with right now are  great switchers but are most eff at like just above 4v, so just wondering if there are some that are more flexible.  I use them for vape hukahs to switch on 3.7v to .2ohm coils. The transistor on res is .0014ohm. Doesnt get beyond just warm without a heat sink. But i really like the low ohm characteristics.

A lot of vape devices use a control board with color display and dc-dc boost with power control levels.  The guy om building them for got into the biz of renting them at night clubs and was doing good till the hukah were failing and the company went under. So im bulding new ones and im just paralleling  18650 cells and running low ohm coils, but on the handles I put 2 push buttons one for full power and one for a lower setting. All the circuits Ive seen either want to use pwm to lower the power or dc-dc boost for more.  I just use a 15k to hold the gate at 0v and the high button puts direct source + and the low button I use a 6.8k res to cause a V division between it and the 15k and it works.  So now the cust dont complain that the thing aint working right because they dont know how to adjust it cuz they are drunk, so just a high n low.. Simple.  No power switches just plug a handle in either side or both and that is the on switch for all the lights, etc.

Has a thick beam laser on top. The new one Im finishing has a laser and a wobble mirror on a cd motor to make a laser cone. Looks crazy when the blow the fog on it.

I make it all with hand tools.

I'm impressed. Do you sell them online? 



I've switched out the transformer in Nelsons circuit and I have my two ribbon TBP stacked on top of each other in parallel instead. Yellow trace is on one coil & gnd and blue on internal tap point. I only get the ring if I use two coils.
