Solenoid Engine Adds Three “Pistons”
https://hackaday.com/2019/10/28/solenoid-engine-adds-three-pistons/
The earliest piston engines typically had only one cylinder, and at best, produced horsepower measured in single digits. But once you have a working engine, it’s a relatively short step to adding cylinders and increasing the power output. [Emiel] made a similar upgrade to one of his engines recently, upgrading …read more (https://hackaday.com/2019/10/28/solenoid-engine-adds-three-pistons/)

The Young Engineers Guide To Career Planning
https://hackaday.com/2019/10/28/the-young-engineers-guide-to-career-planning/
It’s often said that engineers aren’t born, they’re made. Or more accurately, taught, tested, and accredited by universities. If you’re in high school, you’re probably starting to think about potential career paths and may be considering an engineering degree.

Check Your Halloween Candy For Malicious Payloads
https://hackaday.com/2019/10/28/check-your-halloween-candy-for-malicious-payloads/
There’s long been much handwringing around Halloween around the prospect of pins, needles and razor blades being hidden in candy and passed out to children. On the very rare occasion this does happen, the outcome is normally little more than some superficial cuts.
