@all

I got a way to find the new page number  ex i am looking for page 478.

478*10/15+1  319

i hope this help ... page number *10/15+1

It may do well to sand the tips with a coarser grit paper and the sides with finer paper.  I will try this to see what that effect might be.  So much of the light comes out of the ends that it might take 600 grit paper or a little lower to get the desired effect.  They sand easily and it only takes a moment or two to get the frosted effect.

This might make a good video so if I can round up what I need, I may do this again and video it.

That would be great, Bill.

Also you can show the difference as you are doing it instead of just here is my light and there was a different one.
The problem will be the compensation of the camera, but with both at the same time it will be easy to see how it makes a difference.

wow

thank you,

This is good Mark.

If everybody would use reply # instead of page# this won't happen in the future.

Gagdet why is it that one cannot connect the Ucap to a heater filament and then you told me to put a copper wire to see glow???
Cannot understand this cause copper wire have much lesser resistance as heater filament.
This guy had used it on an electric kettle.

Hi . You did not say a heater filiment you said a heater . I thought you meant a plug in heater . No was my answer for that . You need a 110 volt bcap pack for that . now if you have a piece of wire filament yea . That is what i told you and copper wire has almost no resistance and it will glow bright also . That video shows about 3000  dollars worth of bcaps in series to make 24 volts and amperage like crazy . did you see the power supply /inverterthat he used to charge that pack up weighs at least 200 pounds !!and the 24 volt inverter cost about another 4000 dollars or more . I have seen some good ones like trace the one i have cost 5000 dollars but it runs off 24 volts and is made to power the house from solar and stored in 1100 pounds of forklift batteries. If you want to do that you need to spend at least another 4000 to dollars to get the constant current charger and cheap inverter plus another 20 bcaps 10 in series and 10 in parallel or  just as well go to maxwell and order you a 110 volt pack to power all your 110 stuff for about 10,000 dollars !remember i told you these will burn stranded lamp cord into when fully charged . Look .Its yours  but its only 2.7 volts so you cannot run 110 volt heaters . you can run pieces of wire . If you read i said this might heat a hamster cage or a well insulated dog house :)or light ciggs  .Try a Pelteir module on it instead for better heat and cold ! I have done lots of experiment and its up to you to figure out what else can be done . Try It ! Experiment ! you don't need my permission but remember My warnings . These are not TOYS ! they will hurt you burn you electrocute your hand if moist or sweaty  and explode like a bomb if you over charge them . Be careful and have fun . And of Coarse you can ask Me and anyone any questions you have like you are . But its up to you to experiment and see what can be done . Use insulated pliers if your jumping wire . or you will get 3rd degree burns ! . It will take 41 bcaps to power an American nichrome heater coil ! . Use a piece of coPPer wire

@ kooler

I have managed to get better performance from the 0.7 ohm coil There seems to have been two problems. The first is that the protype board was shorting and the second is that I killed my first 2N6399 (probably as a result of the short). Attached is video of circuit 21 except that a 0.5 uF capacitor is being used. Results are similar to the 1.6 ohm coil except that the sparks due not seem to have as much current.

EDIT: Oh, the circuit is definitely putting our over 6KV. I put a 6KV cap across the high voltage output, thinking the output must be lower than that, and I got a spark across the capacitor leads.

@ All:

Here is my video on the LED sanding and diffusion experiments:

It works just fine BUT it does cut down on the light output total and I don't like that.  anyway, for what it is worth, here it is.
