DIY versus Turnkey PCB Assembly with Bald SENSE and MacroFab

My recent experience with the Bald SENSE sensor feather wing project reminded me that time is often our most valuable resource. This video documents the journey that has taught me crucial lessons about design, assembly, and the value of turnkey PCB assembly services. See what went right and what went wrong, and how I ultimately brought this project back to life with the help of MacroFab.

Rohde and Schwarz MXO5 Hands-On

The Rohde and Schwarz MXO5 is the fastest-performing oscilloscope on the market–even when all 8 channels are active! Bald Engineer checks out the precise trigger, ridiculously fast update rate, and a serial decode feature he missed with his review MXO4 review. Check out what is new with the MXO5, how it compares to the MXO4, and some new features available on both.

Measuring Apple II's intentional glitch

The Apple II’s CPU clock has jitter or a glitch. This issue is not new—it has been present since its original design in 1977! Bald Engineer uses an oscilloscope to show how often the glitch occurs and how to correlate that jitter to its source—which is useful when you are not testing 40-year-old devices. The device under test (DUT) in this video is the Mega IIe project. It’s a fully compatible Apple IIe built around the Mega II chip.

KiCad 8 - Bald Engineer's Top 8 Features

KiCad 8 just dropped, and here are Bald Engineer’s 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?

MXO 4 Oscilloscope from Rohde and Schwarz Hands-On / Review

MXO 4 Oscilloscope from Rohde and Schwarz Hands-On / Review

Hands down, no questions asked; the MXO 4 Oscilloscope from R&S is the most impressive scope I have ever used. The main reason I say that is because it is FAST. Over the past 20 years, I have worked for 3 of the 4 top oscilloscope companies (always in technical roles.) So I have used almost every major oscilloscope model for the past two decades. Now, regarding oscilloscopes, “fast” can mean a couple of different things. First, it could mean the bandwidth is very high. The MXO 4 is a low-to-mid-range bandwidth instrument with options from 200 MHz to 1.5 GHz. So, that isn’t what I mean by fast. Second, it could mean how quickly it starts up. And even though it is a PC-based instrument, it is ready to make measurements in about 45 seconds. But that isn’t what I mean.
