Summary
This week's podcast sees Elliot joined by Jenny List, as both suffer silently in the European summer heat as the sound of a desk fan would come over on the recording. The stand-out hack of the week comes from [Bitluni], whose GPU made from thousands of cheap microcontrollers is on a scale we've never seen before. It's an amazing project in itself, but the manufacturing and power consumption issues of so many processors running at the same time make for a discussion of their own. Otherwise, we have diecasting on the bench, an impressive achievement by any measure, a Raman spectrometer, and an open source take on something like a Kei truck. In quick hacks there's a dicussion of soldering versus crimping for high current connectors, and neon tubes used as digital logic in an organ. The recording finishes with a discussion of 7-segment display history, and whether an engineering education teaches design for manufacture. Drop us a comment and check out the links over at Hackaday .
