Mike is the founder of The Geek Pub. A jack of all trades who simply enjoys the challenge creating things, whether from wood, metal, or from lines of code in a computer. Mike has created all kinds of projects that you can follow and build yourself, from many different styles of retro arcade cabinets to Arduino and Raspberry Pi projects.
I’ve had so many people ask me how I went about building the full size R2-D2 remote control system. So today, I will take you through what I have done so far and what I plan to do in the future. When I first started my R2-D2 building adventure I read all the R2-D2 forums […]
In this tutorial, we’re going to show how to do the most awesome Arduino Knight Rider LEDs! It’s a highly requested article after our last update on blinking a single LED we sneak peaked this and apparently, everyone wants to know more! For those who might not know, Knight Rider is a TV show from […]
After my last video introducing the Arduino, some of you commented that you needed an example of how the Arduino works that is super simple to understand. So in this video we’re going to do the absolute simplest of projects. We’re going to be blinking an LED! Arduino: Blinking an LED Video We’ve made detailed […]
In this tutorial, we’re going to do an introduction to the Arduino! I think a lot of people confuse them with the Raspberry Pi line of single board computers, and they are very different products that do similar but different things. I’m sure if you’re even the slightest bit geeky or at all into DIY […]
If you’ve recently ran an apt upgrade on your Raspberry Pi you might have noticed a bunch of lines scrolling up the screen saying “rpikernelhack” that freaked you out! What is rpikernelhack and why is it running on your Raspberry Pi?? Understanding rpikernelhack When the developers of the Raspberry Pi were designing the device and […]
Many people pour hours and hours into developing a project on their Raspberry Pi and never put any though in how to back up their work. A Raspberry Pi is a used a lot for prototyping and electronics learning projects. It’s a super fantastic computer for these purposes and even includes a full set of […]
The ultrasonic sensor is one of the most common sensors used in Arduino projects. It’s one of those must have sensors for many projects that require inputs for navigation. For example, an Arduino RC car or other robot will likely need an ultrasonic sensor to measure how close it is to a wall or other […]
In this tutorial let’s talk about UART communications basics! A UART (short for Universal Asynchronous Receiver/Transmitter) is an electronic component that you’ll find in all sorts of electronics. UARTs have been around since the early days of PCs and were mostly associated with MODEMs of the time because a high quality MODEM would of course […]
This update is going to be all about the R2-D2 dome build, specifically the mechanical and electronics portion for automating the pie panels. This was actually one of the most frustrating parts so far. Not because the work was all that hard, but because much of the componentry that is sold flat out does not […]
One of the best features of the Arduino is the ability to control relays. Relays allow a circuit of one voltage or current to be operated by a circuit of a different voltage or current. In the case of an Arduino that operates at either 3.3V or 5V DC, connecting a relay allows us to […]
