Re: An energy producing Fusor

<t>hi roger,<br/> <br/> well, this is a bit of a pointless rant on symantics, but since energy can not be created, a fusor can not produce energy. it can however liberate energy from the nuclear reactions that take place within it.<br/> <br/> that said, as it is, the fusor can not be used to produce...

Re: builting a scintillator

thanks jon,
that's a great site. actually, the ccfl inverter based hv supply is what i'm using. it works well, but i cant get a very clean output from it. richard's cascade rc filter suggestion seems to be working well though.

Re: builting a scintillator

thank you, richard!

soon, i plan to post some pictures of my progress in the images section. this project is coming along quite nicely- even though it's at a snail's pace.

building a scintillator

<t>i've searched the archives and come up with squat, though i'm sure i've seen this question before.<br/> anyway, in making my scintillator i've come across a couple of problems that i'm trying to figure out. i'll get to those in a moment.<br/> <br/> but first, as i'm working on the detection porti...

Re: Source for Uranium Metal?

so, is there a reason why thorium metal has been added to the non-obtanium list? or is it yet another example of regulation without reason?

Re: Source for Uranium Metal?

<t>as i understand it, it is very illegal to do anything with your ore samples other than look at them and listen to the hum of a counter. <br/> this is to bad; i've recently aquired an excellent book regarding radiochemestry and half the book deals with ways to extract specific isotopes. <br/> ...n...

Re: Aerogel in a fusor

i would suspect that it would out gas terribly at the presure of a running fusor. but i would certainly be interested in how to make it. home grown capacitors anyone?

Re: pulse totalizer/ rate meter

<r>thanks again richard,<br/> i enjoy projects like this. i learn a lot along the way. i could just buy a scintillator, but then i learn very little. <E>:)</E><br/> <br/> anyway, i have a simple preamp similar to your reverse engineered 3 transistor circuit to feed the monostable and integrator. for...

Re: pulse totalizer/ rate meter

<t>thanks richard!<br/> yeah, i'm not even going to try this without a good o'scope. i dont have a good one, but the local university does....<br/> <br/> a monostable circuit, eh? actually i was thinking about that but i figured it would limit the number of pulses that made it through to the meter. ...

pulse totalizer/ rate meter

<t>in making my scintillator i have come across a bit of a dark area in my knowlege. how does one use an analog panel meter to indicate counts/min?<br/> here's what i am trying to do:<br/> i have a victoreen cdv-715 (the ionization chamber based survey meter) that i bought mainly for parts (it had t...
