In KiCad 6, using the Polygon tool makes square boards easy. Just select the Edge.Cuts layer, then the polygon tool, and draw a square. However, if you want custom shapes, then you need to connect multiple line segments together. If you are not careful, the segments will not connect and you might get one of two errors. The first comes when you run DRC. Error: Board has malformed outline (not a closed shape) or, if…

Thank you again to those who came over from RSS to say the old feed was working. Also. My apologies for the rash of new posts. I *thought* I had a clever way to prevent them from appearing in the feed. Let me know if you see any issues. New (real) posts will start in the next week or two.

Using a Metcal GT120, we look at three ways to improve your soldering skills. Using flux, setting a correct temperature, and selecting the proper tip all result in better solder joints. See how well the GT120 works while learning (or reviewing) some basics to improve your soldering skills. This episode was sponsored by Metcal.

When you cannot get an oscilloscope probe into a tight spot, can you just use a piece of wire? Sometimes. When signal integrity matters, you CAN use a low-cost DIY solder-in probe. These probes attenuate the signal and use an oscilloscope’s high-bandwidth 50-ohm input. James shows how to build some solder-in probes when they work and when they do not work in this video.
