PART 1 is HERE: http://www.youtube.com/watch?v=CIGjActDeoM Part 2 of Dave's Open Hardware constant current linear regulated lab power supply design. An in-depth look at the LT3080 datasheet, the LM334 current source, and a few more circuit tweaks before it's ready to build in the next episode to see if it works!

and the winner is...

NOTE: This is a new version in 1080 50p The founder and CEO of Ness Corporation Naz Circosta takes us on a personal tour of the companies impressive worlds class surface mount and through hole manufacturing facility where they produce hundreds of different Ness security and automation products. It's no every day the CEO of a major company has the technical knowledge to take you on such a tour of their own production facilities! He shows the Yamaha SMD/SMT pick and place machines, solder stencil paste machine, flying probe testers, optical vision inspection equipment, custom test jigs, and plastic ultrasonic welding machines. And also talks about buying a $1M Objet 3D printer, and the advantages of genuine high quality Fresnel lenses vs cheap generic ones in PIR sensor performance.
