Collaborate Disseminate
To those who choose to overclock their PCs, it’s often a “no expense spared” deal. Fancy heat sinks, complicated liquid cooling setups, and cool clear cases to show off all the expensive guts are all part of the charm. But not everyone’s pockets are deep enough for off-the-shelf parts, so …read more

There are many ways to keep critical appliances running during a power outage. Maybe a UPS for a computer, a set of solar panels to charge your phone, or even a generator to keep your refrigerator or air conditioning working. This modification to a standard blender will also let you …read more
Lithium batteries and brushless motors helped make multirotor drones possible, but batteries only last so long. Liquid fuels have far greater energy densities, but have not been widely applied in these roles. [Tech Ingredients] has been experimenting with a compact gasoline-fueled generator, with the aim to extend drone flight times …read more

Multirotor drones truly took off with the availability of lithium polymer batteries, brushless motors, and cheap IMUs. Their performance continues to improve, but their flight time remains relatively short due to the limits of battery technology. [Nicolai Valenti] aims to solve the problem by developing a hybrid generator for drones. …read more

Russia has long been known for making large machines. They hold the current record for the largest helicopter ever made – the MiL V12. Same goes for the world’s largest airplane, the Antonov An-225. Largest submarine? Yep, they made that too – the Typhoon class. It would appear they’ve thrown their hat in the drone business as well.
While the SKYF drone is made by a private Russian company, it is one of the largest drones we’ve ever seen. Able to lift 400 pounds (a Phantom 3 weighs 2.8 pounds) and can fly for eight hours, the SKYF drone is …read more

Researchers are worried that doctors treating refugees might misdiagnose the resulting illness as pneumonia. Continue reading African Refugees Say They’re Being Forced to Inhale Gasoline as a Sedative
[amazingdiyprojects] has been making lots of test flights in his crazy eight propeller gasoline powered danger bucket.
We last covered the project when he had, unfortunately, wrecked the thing in a remote-controlled test flight. He later discovered that the motor’s crankshaft bearings had, well, exploded. The resulting shrapnel destroyed the motor and crashed the drone. He described this failure mode as “concerning”.
Also concerning is the act of stepping into the seat once all the propellers are started up. He tags this as “watch your step or die”. Regardless, he also describes flying in the thing as so incredibly fun …read more
