    Robert, please e-mail me at my profile account e-mail. I’d like to try and hook you up with a very saavy nuclear/electronics engineer I know who has been to that site, knows people, etc. Hopefully, he can answer specific questions, and give you reccomendations as far as procedures, places to check out (where allowed), contacts, etc. This is just an offer to try and put you in contact with a friend who can help you get the most from the experience. Take care.

    People stopped daring to call Dave “Monkeyboy” once he showed them the size of his banana….

    Maybe off topic, but given how you can find surplus LED’s cheap, here’s a fun little game I used to play with other geek friends. Take two LEDs, and a slot car race set–remove the cars. Now, put one LED in the slot for one car, a second in the slot for the second car–make sure that the polarity in the tracks is such that the LED' are forward biased. Now, using the slot car controllers, the goal is to see who cam make their LED light the brightest the longest before it burns out or explodes. :) It can be suprisingly tricky to accomplish. Safety glasses and fire extiguisher reccomended :D

    Safety note: Combining the igniter and the pads would be a very BAD idea :p Just sayin'… I may have to order one of these and measure the high voltage output, verify its switchng frequency, add in a voltage multiplier…make a beam on target neutron gun to activate a sub-critical pile…Hey, kids, let’s make a desktop nuclear reactor! That shold DEFINATELY win the science fair…or else…:p

    I want to remind everyone of the main purpose of the protest by all the companies and sites–to encourage Americans to write and/or call their representative. You may not think it makes a difference, but I read once that every letter a congressman receives they figure represents at least 10,000 voters. If you believe in this issue, please, make the effort to contact your representative and express your view. We are still supposed to have a representative form of government in this country. Make them listen and respond, or accept the consequences for what they do for themsevles in the name of money and power. And if your representative votes for this–make your voice heard again by writing him before election time, and explaining why you are voting for his opponent. If he votes against it, and he maintains a track record you approve of, write him again before election time and let him know why you WILL be voting for him. Carrot and stick.

No public wish lists :(
