Developed by Max Dovey, an artist and researcher at the Institute of Network Cultures, Breath repurposes a medical tool called a spirometer that measures how much air is inhaled and exhaled by your lungs. This data is then fed to a small computer mining on the Monero blockchain.
While a user’s breath doesn’t actually power the computer, it does determine the computer’s hashrate, which ultimately determines how much Monero the computer can mine. According to Breath’s website, 1 puff per second equates to the computer performing 1,000 hashing operations per second. This may sound like a lot, but it’s just a drop in the ocean of the Monero network’s total hashrate: Around 500 million hashes per second.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
