Using a Coolidge tube, an arduino, and some high voltage know how, aspiring radiologist and maker Grenadier built a portable X-Ray machine with nixie tube display and light up dials. As with most projects this cool, it’s probably a good idea to investigate all safety precautions prior to attempting to recreate it, right? [via Technabob]

Here’s a test image as viewed through a scintillator:

  3. Looks like Grenadier is on the way to  becoming an amateur TSA agent!

    Excellent work! I was wondering, what are you using for your scintillator? It looks pretty good. Is it just NaI painted material? I would really like to know, thank you.

     yeah… but we’ll need about 137 smoke detectors and a whole buncha duct-tape (cuz it goes without saying that without enough duct-tape a melt-down remains a terrible threat)
