A DIY Tracker Tough Enough for the Arctic

Cars That Think

But it’s a tough environment for scientific instruments. So, I set about building an open-source ice tracker from DIY components that not only proved to be much, much cheaper but also much more capable than the commercial options. This is fast enough to identify wind waves, which typically have a frequency of about 0.2

Search for Buried Treasure With This DIY Magnetometer

Cars That Think

So when the coil is pointed north ( and downward, at my northern latitude ), the Earth’s magnetic field adds to the magnetic field created by positive currents in the coil windings; when pointed in the opposite direction, the Earth’s field subtracts. This article appears in the May 2022 print issue as “A DIY Magnetometer.”.

Build a Passive Radar With Software-Defined Radio

Cars That Think

I really wish more companies would adopt this approach, as installing open-source software is often a frustrating exercise in trying to replicate the precise system environment it was developed in. This was in a bid to shield the antenna from the reference signal and myself from the wind.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

7 Uncle B said on April 14th, 2009 at 10:17 am This battery is going to absorb peaks from wind-turbines, hitherto dumped to prevent damage to lines! A really significant efficiency increase will be realized, and in combination with the new “variable&# alternators from Vancouver, Canada, major wind power efficiencies can be anticipated!

How I turned a shipping container into a solar off-grid charging station with A/C

Baua Electric

Well, not really cheated, but I just went with a retail solar generator system instead of DIYing that part myself from à la carte components. And the answer is to hopefully give them better wind protection. There are many ways to skin a cat, and even more ways to add solar power to a shipping container. To be fair, I cheated a bit.
