This video is part of a 3 part series, with the other two parts coming in the future. When it’s time to design a custom PCB for your project, you might be wondering how to design in an Arduino. This video shows the pieces that go into the schematic. The next video will show how to layout the PCB. And after the boards come back, I will show how to turn it on. Related Videos…
A common question that comes up about pull-up resistors: what value do you pick and why not just use a piece of wire? In this follow-up electronics tutorial, the bald engineer looks at how to pick pull-up resistor values.

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.

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.

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.
My new laser cutter didn’t seem to work. I tried all of the usual troubleshooting steps. Then, I got the idea to use a special kind of tool. Behind the scenes All of the sound effects you hear are ones that I added: “in post.” The footsteps, the laser cutter, and (obviously) the lightsaber were all recorded separately. I used the Adobe After Effects plugin Saber from Video Copilots to do the glow. If you…
Here are 8 questions you’ve sent in. Rare (at least, up until now) video of James talking unscripted. Questions answered in this video: 1. Why does AC change direction?2. What do home appliances run on?3. Is Analog or Digital More Accurate?4. When do you use Pull-down resistors?5. Difference between LM7805 and LM7812?6. What diode to pick for a motor’s flyback diode?7. Does James draw his own Animations?8. What does “AddOhms” mean?
<br /> This Addohms Brushed DC Motor Tutorial goes into the third dimension! Using a variety of 3D models, we show you what makes a brushed DC motor, a brushed DC motor. Then, like usual, we break two simple ways to control them with a microcontroller like the Arduino. You can use a single BJT Transistor (remember those from #10?), build your own H-Bridge, or use a popular H-Bridge chip. Brushed DC Motors Show Notes This…
