KiCad 8 just dropped. Here’s an AddOhms video covering eight must-try features! The February 2024 release brings a whole host of new stuff to the Schematic editor. However, the PCB editor, CLI, and Simulation tools also received attention. (There are something like 900 closed issues for the 8.0.0 Milestone!) Which of these is your favorite? https://www.youtube.com/watch?v=Ohxlmy0p7FE In the video, I cover: Property Manager Panel (is now everywhere) A fix for Symbol pin or wire end…
Learning to use a new oscilloscope can be daunting. In this video, I show 5 measurements you can make using just an Arduino as your DUT. Learn how to offset voltage, setup measurements, enable infinite persistence, save reference waveforms, AND trigger (and decode) serial signals. For this video, Rohde & Schwarz was kind enough to send me an RTM3004. This video is a follow-up from an ealier blog post which featured 6 scope measurements you…
As promised, the Arduino team shipped the MKR 4000 VIDOR by the end of July. The graphical editor is still missing in action, but you can check out the board now. I received mine. In this AddOhms Live Stream, I turned it on and checked it out. This video is a “working” live stream. Generally, I try to set up some demos and run through some canned actions. Not this time. I used the board once,…
This AddOhms episode is part 3 of the “design your own Arduino” series. In this one I populate a bare PCB, reflow solder it, debug a few issues, and load the Uno bootloader. Originally, I designed 2 versions of the board. One version contained an error that I planned to fix in the episode. Well, turns out, the “correct” board had two issues which were more interesting. Check out the #27 show notes for links…
This week the bald engineer unboxes swag from electromaker.io, programs the Adafruit Coin Accepter, with a Pyramiduino, and answers questions along the way. Interesting time code jump points: 7:59 – See Programming Bootloader Clip 12:11 – Coin Acceptor Programming 18:00 – Pulses on the R&S RTM3004 Oscilloscope 42:05 – Code working as intended!
