Sergey Sharybin and Martijn Berger presented this awesome real-time Blender bug-o-meter during the Blender Conference.
It is a 11x11x11 cm acrylic laser cut box. containing a Raspberry Pi and a custom nixie driver designed by Sergey. It started out as a joke but we decided to make it real. The print (details here) is custom made (we still have some and will sell / provide at cost to interested parties). The acrylic was designed in Blender and laser cut at Laserbeest in Delft out of 5mm clear acrylic. The digits are IN12-a nixie tubes from the former USSR.
The meter currently rotates around in the studio, on the desk of whom has bug fix duties that day. Currently that is: Monday for Campbell, Tuesday for Sergey,Wednesday for Lukas and Thursday for Antony.
