The Next Generation Arduino Nano
https://hackaday.com/2019/10/10/the-next-generation-arduino-nano/
While we certainly do love the Arduino Nano for its low-cost and versatility in projects, it’s unarguable that every tools has its gripes. For one maker in particular, there were enough complaints to merit a redesign of the entire board. While Arduino may or may not be interested in incorporating …read more (https://hackaday.com/2019/10/10/the-next-generation-arduino-nano/)

Minature Table Saw Gets The Teeny Jobs Done
https://hackaday.com/2019/10/10/minature-table-saw-gets-the-teeny-jobs-done/
Table saws are highly useful tools, but tend to take up a lot of space. They’re usually designed to handle the bigger jobs in a workshop. It doesn’t have to be that way, however, as [KJDOT] demonstrates with a miniature table saw.

Fail of the Week: How Not to Re-Reflow
https://hackaday.com/2019/10/10/fail-of-the-week-how-not-to-re-reflow/
There’s no question that surface-mount technology has been a game-changer for PCB design. It means easier automated component placement and soldering, and it’s a big reason why electronics have gotten so cheap. It’s not without problems, though, particularly when you have no choice but to include through-hole components on your …read more (https://hackaday.com/2019/10/10/fail-of-the-week-how-not-to-re-reflow/)

CPU Showdown for Pancakes
https://hackaday.com/2019/10/11/cpu-showdown-for-pancakes/
If you ask people how they rate as a driver, most of them will say they are better than average. At first, that seems improbable until you realize one thing: people judge themselves by different criteria. So Sally thinks she’s a good driver because she goes fast.
