EEVblog #726 - Dual Xeon Video Editing Machine Build
Dave builds and tests the 24 core dual processor 2.6GHz Intel Xeon E5-2630 v2 video editing machine and benchmarks against his current 8 core i7 3770K machine at 3.5GHz. This is one hour of PC building and software testing, if you find this stuff boring, DON'T WATCH IT! Forum: http://www.eevblog.com/forum/blog/eevblog-726-dual-xeon-video-editing-machine-build/
CORRECTION: The i7 3770K is actually running at 3.7GHz UPDATE: Even doing a 1 hour render at 240W consumption, the heatsinks do not even get warm to the touch.
Dave explains what Vacuum Fluorescent Displays (VFD's) are, how they work, and then hacks an interface and reverse engineers a surplus Babcock VF-0240-7 display from an industrial machine to make it work with an Arduino.
UPDATE: Found the datasheet: http://www.eevblog.com/files/Babcock-VF0240.pdf
