Hackaday Links: March 18, 2018

Oh, boy. You know what’s happening next weekend? The Midwest RepRap Festival. The greatest 3D printing festival on the planet is going down next Friday afternoon until Sunday afternoon in beautiful Goshen, Indiana. Why should you go? Check this one out. To recap from last year, E3D released a new extruder, open source filaments will be a thing, true color filament printing in CMYKW is awesome, and we got the world’s first look at the infinite build volume printer. This year, The Part Daddy, a 20-foot-tall delta bot will be there once again. It’s awesome and you should come.

We launched the 2018 Hackaday Prize this week. Why should you care? Because we’re giving away $200,000 in prizes. There are five challenges: the Open Hardware Design Challenge, Robotics Module, Power Harvesting, Human-Computer Interface, and Musical Instrument Challenge. That last one is something I’m especially interested in for one very specific reason. This is a guitorgan.

Building a computer soon? Buy your SSD now. Someone fell asleep on the e-stop at a Samsung fab, and now 3.5% of global NAND production for March has been lost.

Need to put an Arduino in the cloud? Here’s a shield for that. It’s a shield for SIMCom’s SIM7000-series module, providing LTE for a microcontroller. Why would you ever need this? Because 2G is dead, for various values of ‘dead’. 3G is eventually going to go the same way.

A bridge collapsed in Florida this week. A pedestrian walkway at Florida International University collapsed this week, killing several. The engineering efforts are still underway to determine the cause of the accident, but some guy from Canukistan posted a pair of informative videos discussing I-beams and pre-tensioned concrete. It’s going to be months until the fault (and responsibility) will be determined, but until then we have the best footage yet of this collapse. It’s dash cam footage from a truck that rolled up to the red light just before the collapse. This is one that’s going to go down in engineering history along with the Hyatt Regency collapse.

Need to test your app? Here’s a delta robot designed for phones. You would be shocked at how popular this robot is.
