Fresh hacks every day
When we first started hearing about software-defined radio hacks (which often use USB dongles that ring it at under $20) we didn’t fully grasp the scope of that flexibility. But now we’ve seen several real-life examples that drive the concept home. For instance, did you know that SDR can be used to track ships? Ships large and small are … Read the rest
This Lego watercraft uses drinking bottles as pontoons arranged in a pattern that make it look very much like a Water Strider, the insects that dance on the surface of a lake.

A team of four college students decided the best way to get a small boat across the ocean would be to remove the human element from the process, so they set … Read the rest
The Protei project aims to develop a robotic solution for oil-spill cleanup. [Cesar Harada] quit what he calls his dream job at MIT to work toward a solution to the ecological disasters that are oil spills. He had previously been working on Seaswarm, a swarm of robots that use conveyor belts of absorbent material to leech oil from seawater. … Read the rest
[Kevin Sandom] built this boat using a radio controlled toy car. The two pontoons are recycled from Styrofoam packaging material using some thick wire to connect them and provide a framework for the propulsion and control circuitry. The motor itself is a hobby outboard, which really only required [Kevin] to develop a method for steering. He walks us through the … Read the rest
Who could not love the tender glow of a Nixie display? It isn’t a new concept for them to be used in clocks, and usually it’s how they are housed or encased for display that sets them apart.
