Could an entire Fusor be 3D printed?

<r>Making parts, such as the grid, with 3D printers has come up a few times, however none recently, in the past such as:<br/> <br/> "New idea for making a grid"<br/> <URL url="http://www.fusor.net/board/download_thread.php?site=fusor&bn;=fusor_construction&thread;=1274053797#N1274053797"><LI...

Re: Hearing Radiation

<r>> Thanks. If the program were just for me, I would not need to scan to find the USB ID and I could get it on my own but I am trying to make a generic program that could be run by others. That is also the reason I was looking at either sound card input or a DAQ type device. Guess either way a prea...

Re: Hearing Radiation

<r>> What I am not sure about is how to get the data in. I see some pre written programs to scan for USB ports but this is all new to me and I am not sure if it is better to get the data from a DAQ or from input from a soundcard as Steven's Gamma Spec unit does. Any thoughts on the front end of this...

NASA on generating Neutrons

<r>I'll admit right up front I'm not sure this is on topic, if not please (re)move it. Thought it was worth bringing up due to the NASA connection to making Neutrons.<br/> <br/> In a video on NASA's Technology Gateway they are discussion Low Energy Nuclear Reactions (AKA Cold Fusion). The video clea...

Re: Computer interfacing

Watch the input impedance of the low end Dataq units, it can be as low as 50k.
