We take a look at EAGLE 9.0. This release was a major update since Autodesk took over the project. To help, I used a class I wrote for TechShop as a guide. In the end, I was happy to see the progress Autodesk has made. However, I’ll be sticking to KiCad.

Part two of the DIY Arduino series. In this video, we create the PCB. Also, the project gets a new name: Pyramiduino. Watch the process to make a PCB in KiCad. And the Bald Engineer gives you a challenge, can you find the unconnected nets before he does? Check out Part 1 - the Schematic and subscribe to see when Part 3 - Turn On is posted. DIY Arduino PCB in KiCad Show Notes Pyramiduino Project on GitHub Getting to Blinky: KiCad tutorial from Conextual Electronics OSHPark- Bald Engineer’s preferred PCB supplier. (They provided the boards for free for this project.) Related Videos Part 1: Creating DIY Arduino Schematic in KiCad Part 3: Soldering and testing DIY Arduino

To be upfront, I am not a subscriber anymore. The owner of the company has a history of berating customers on Twitter. So, I just cannot support them anymore. I’d recommend you look at Adafruit’s AdaBox instead.

Previously, we looked at resistor voltage dividers. Sometimes I get questions about using these instead of regulators. In this video, I show why that doesn’t work. In fact, I go one step further and show that Zener regulators do not work either. Voltage Divider as a Regulator Show Notes Other videos to watch #13: Voltage Dividers #7: Comparing Uno to Pi #17: Linear Regulators Links Zener Diode makes for a lousy regulator 3 (baldengineer.com) In the episode, I am featuring the Adafruit Huzzah ESP8266 breakout 4. I highly recommend this board if you are interested in the ESP8266. It doesn’t have a serial to USB interface. However, it is far more reliable (and usable) than those worthless $5 8266 boards on eBay. (By Far.)

Another kind of motor is the BLDC. Otherwise known as the Brushless DC Motor. Unlike the motors we talked about in #20, a BLDC has no commutation ring or brushes. This means no sparks, longer life, and very fast RPMs. Commutation is done electrically. In this video, we show the inside of a BLDC and show two ways to control one.
