Nuclear Fusion Power Without Regular Tokamaks Or Stellarators

When it comes to nuclear fusion, the most well-known reactor type today is no doubt the tokamak, due to its relatively straight-forward concept of plasma containment. That’s not to say that there aren’t other ways to accomplish nuclear fusion in a way that could conceivably be used in a commercial power plant in the near […]

The Young Engineers Guide To Career Planning

It’s often said that engineers aren’t born, they’re made. Or more accurately, taught, tested, and accredited by universities. If you’re in high school, you’re probably starting to think about potential career paths and may be considering an engineering degree. A lot of work goes into a good college application, and it might seem like the […]

RTFM: ADCs and DACs

It’s tough to find a project these days that doesn’t use an analog-to-digital converter (ADC) or digital-to-analog converter (DAC) for something. Whether these converters come as built-in peripherals on a microcontroller, or as separate devices connected over SPI, I2C, or parallel buses, all these converters share some common attributes, and knowing how to read the […]

Books You Should Read: Exact Constraint: Machine Design Using Kinematic Principles

Surely, if you’re reading this website you’ve teased the thought of building your own 3D printer. I certainly did. But from my years of repeated rebuilds of my homebrew laser cutter, I learned one thing: machine design is hard, and parts cost money. Rather than jump the gun and start iterating on a few machine […]

Following Pigs: Building an Injectable Livestock Tracking System

I’m often asked to design customer and employee tracking systems. There are quite a few ways to do it, and it’s an interesting intersection of engineering and ethics – what information is reasonable to collect in different contexts, anonymizing and securely storing it, and at a fundamental level whether the entire system should exist at […]

Tuning into Atomic Radio: Quantum Technique Unlocks Laser-Based Radio Reception

The basic technology of radio hasn’t changed much since an Italian marquis first blasted telegraph messages across the Atlantic using a souped-up spark plug and a couple of coils of wire. Then as now, receiving radio waves relies on antennas of just the right shape and size to use the energy in the radio waves […]
