Proprietary components are the bane of anyone who dares to try and repair their own hardware. Nonstandard sizes, lack of labeling or documentation, and unavailable spare parts are all par for the course. [Jason] was unlucky enough to have an older Dell computer with a broken, and proprietary, cooling fan …read more
A study of 406 cold-blooded animals revealed that climate change is already pushing marine species to their thermal limits. Continue reading Global Warming Is Wiping Out Marine Animals Faster Than Land Dwellers
Do you have a need to photographically document the doings of warm-blooded animals? If so, a game camera from the nearest hunting supplier is probably your best bet. But if you don’t need the value-added features such as a weather-resistant housing that can be chained to a tree, this DIY motion trigger for a DSLR is a quick and easy build, and probably loads more fun.
The BOM on [Jeremy S Cook]’s build is extremely short – just a PIR sensor and an optoisolator, with a battery, a plug for the camera’s remote jack, and a 3D-printed bracket. The PIR …read more

Liquid cooling is a popular way to get a bit of extra performance out of your computer. Usually this is done in desktops, where a special heat sink with copper tubing is glued to the CPU, and the copper tubes are plumbed to a radiator. If you want dive deeper into the world of liquid cooling, you can alternatively submerge your entire computer in a bath of mineral oil like [Timm] has done.
The computer in question here is a Raspberry Pi, and it’s being housed in a purpose-built laser cut acrylic case full of mineral oil. As a SoC, …read more
InSight is the first Mars mission to focus on the red planet’s interior, and will drill a hole five meters into its surface. Continue reading NASA Successfully Landed Its Digging Robot on Mars
The latest craze in revolutionary materials science is no longer some carbon nanotube, a new mysterious alloy, or biodegradeable plastic. It seems as though a lot of new developments are coming out of the biology world, specifically from mycologists who study fungi. While the jury’s still out on whether or not it’s possible to use fungi to build a decent Star Trek series, researchers have in fact been able to use certain kinds of it to build high-performing insulation.
The insulation is made of the part of the fungus called the mycelium, rather than its more familiar-looking fruiting body. The …read more
Every year, we demand our computers to be ever faster, capable of delivering progressively more eye-watering graphics and doing it all as reliably as ever. Unfortunately, sometimes, new designs miss the mark. [Cloakedbug] was having issues with voltage regulator temperatures on an ASUS Strix VEGA 64 — one of the latest RADEON graphics cards on the market — and decided to investigate.
Right away, issues were apparent; one of the main thermal pads was making poor contact with the FETs it was intended to carry heat for, and was poorly sized to boot. In a show of poor quality, the …read more

A backyard swimming pool can be a great place to take a refreshing dip on a summer’s day. It can also be a place to freeze your giblets off if the sun has been hiding for even a few hours. That can make pools an iffy proposition unless they’re heated, and that starts to get really expensive in terms of upfront costs and ongoing charges for fuel or power. Unless you put the sun and the IoT to work for pool-heating needs.
Preferences vary, of course, but [Martin Harizanov] and his family clearly like their swims on the warm side. …read more
Researchers put young people in old, hot dorms during a Boston heat wave, and found that their memories and cognitive speed was worse that their AC-chilled counterparts. Continue reading Study Shows Heat Hurts Cognitive Ability
The Action Lab did an experiment to show how the energy of sound can be converted into heat, and even cook food. Continue reading Can You Cook an Egg by Screaming at It?
