Fresh hacks every day
This hot air rework station is being used for more than just soldering surface mount components. Since it has settings for temperature and airflow [BrokeHippieTech] figured it would work as a bag vaporizer. In the video after the break they show off the custom parts and then take it though and herbal blend bag fill.
The hot air station … Read the rest
[James] has been building a heart rate monitor using a very cool TI chip. He needed a way to test his device, and commercial ECG simulators, like all biotech devices, are absurdly expensive. [James] decided to build his own heart rate simulator, and in the process made a great tool and one of the most well documented projects we’ve … Read the rest
After building a homebrew x-ray backscatter imager, [Ben Krasnow] realized he had nearly all the components to build his own CT scanner, able to make a 3D model of the inside of a frozen chicken.
Basically, a CT scanner takes dozens of x-rays of an object and reassembles them with the help of fancy algorithms to allow doctors to … Read the rest
[Michael], [Tom], and a few other people on the Lucid Scribe Database project have been using off-the-shelf EEG equipment to invoke lucid dreaming. Yes, that’s where you take control of your dreams and become a god. This requires wearing an EEG setup while you sleep, and these products aren’t very comfortable sleeping wear. [Tom] decided to take apart a NeuroSky … Read the rest
The last time you were in the emergency room after a horrible accident involving a PVC pressure vessel, a nurse probably clipped a device called a pulse oximeter onto one of your remaining fingers. These small electronic devices detect both your pulse and blood oxygen level with a pair of LEDs and a photosensor. [Anders] sent in a great tutorial … Read the rest
The natural movement and functional power of the ankle and foot during a step , while appearing fairly simple, are amazingly difficult to replicate with a prosthetic. Usually it requires a fast and fairly powerful motor to provide the forward push and then whip that foot up as we pull our leg forward. However, recent projects have managed to do … Read the rest
If one hack that controls amputated cockroach legs this week wasn’t enough for you, we’ve got another.
Earlier this week we saw two neuroscientists at Backyard Brains put on a show at a TED talk by connecting an amputated cockroach leg (don’t worry, they grow back) to a $100 electronic device called the SpikerBox. The SpikerBox allows students to … Read the rest
