I am building the e-bike of kayaks. So how do you control a DIY electric kayak? With a phone app? With a remote control? All while trying to hold a kayak paddle? I wanted the user interface to feel as natural as possible without removing you from the actual experience of kayaking. This Instructable shows …

I’ve always loved the water. I was a life guard, work on UUVs (Unmanned Under Water Vehicles) as a career and I’m Norwegian. Living in Seattle, being surrounded by so much water, I’ve wanted to build my own electric kayak for a long time! I have also wanted to do a project involving machine learning …
The power source is a vital part of every electronics project. From solar energy and EVs to portable game consoles and smart phones, batteries make up the vast majority of these power sources. So why do most engineers never learn about battery sizing in school? I’ll walk you through how to choose the right battery …
How to Choose the Right Battery for Your Project Read More »
Some time ago, I started seriously tossing around the idea of building my own electric motorcycle. The reality of my one bedroom Seattle apartment, the time commitment and the costs of the battery alone all set in and I realized I might have to put this project on hold. But while pondering the build, I …
A Schmitt Trigger is a very practical circuit that helps eliminate switching noise on an input signal by implementing what is called hysteresis. Imagine you have a system that feeds a 0 – 5V signal into a rising/falling edge GPIO interrupt. With no Schmitt Trigger, the interrupt would trigger anytime the signal rises or falls …
One major advantage of object oriented programming (OOP) languages like C++ is polymorphism. Polymorphism is defined as, “The condition of occurring in several different forms”. In OOP, this would mean the compiler’s ability to infer the right function call / behavior based on the input data alone. For example, when calling an add function the …
The need for complex graphics and communication stacks in modern embedded projects has grown exponentially. WIFI, Bluetooth and MIPI are just a few examples that come to mind. This is where embedded linux thrives. If the extra costs can be absorbed, the use of embedded Linux will save tons of hours in development time for …
Whether graduation, Christmas or Birthdays, I am notoriously hard to shop for. Most of what I want is related to electronics or tools that my family members have no interest in. Sifting through the endless tacky engineering shirts and cheap hacky “tools” can be overwhelming for the uninitiated. So I have done the endless scrolling …
Meet Gourdan, the Jack-O-Lantern who follows tricker treaters to the door and back with his eyes. My sister and I both married Halloween fanatics. Anything from scary movies to decorations, our spouses love everything spooky. Growing up I hated scary movies and my family never really got into the Halloween spirit. In fact I remember …
It’s time to dump the breadboard rats nest and say hello to the Proto-Power Hat. Get organized, get making and finish twice as many projects as ever before! Every Raspberry Pi project that I have worked on has needed the following three things: a power button, active cooling and extra voltage rails. After re-building …
