David Prutchi has just put together a DIY Gamma-Ray Probe using a Philips XP5312/SN photomultiplier tube and a piece of scintillation plastic. A paint can was selected as a nice solid enclosure, the tube and plastic are supported by some foam on the inside to protect them from damage. “The probe yields a background count of approximately 1,000 counts/minute (cpm) in our lab, and 7,400 cpm from a 137Cs
You might remember a few years ago when I shared how I monitor my running CNC machine. Looks like Dave from Plastibots has added a cool twist to the idea. Dave uses a wireless IP camera to monitor his equipment but he also came up with a way to wirelessly e-stop the machine by remotely pressing the escape button if the system is acting up. Instead of coming up
 If you like to dig through your bag of skittles to eat all of one color before moving on to the next this Skittles Sorting Machine might be just for you.

Lots of work went into moving some sliders and buttons around so that it will work in the new form factor. Ben uses a neat trick to make the new front face fit all of the existing buttons. He takes a scan of the
Our friend Bob Davis has been working with some Signature Electronic Signs. He didn’t like the complex controller that came with the device so he made a controller based on the arduino to control the sign. You can see the code that makes the system work here. These displays are available on Ebay at some reasonable prices, Bob describes some of technical details of the display here where he
