One of the easiest ways to measure body fat is by using hydrostatic weighing. It is based on Archimedes' principle, the law of buoyancy. It works by calculating body fat from measuring the amount of displaced water after a person has been immersed under water. Since muscle is denser than body fat, a person who has more muscle will displace less water than a person of the same weight with more body fat. This test is usually performed for a couple times for averaging accuracy. If the test is do...

How To: Change a Phone's Coordinates by Spoofing Wi-Fi Geolocation Hotspots

In many urban areas, GPS doesn't work well. Buildings reflect GPS signals on themselves to create a confusing mess for phones to sort out. As a result, most modern devices determine their location using a blend of techniques, including nearby Wi-Fi networks. By using SkyLift to create fake networks known to be in other areas, we can manipulate where a device thinks it is with an ESP8266 microcontroller.

How To: Make an infrared heart sensor

This video shows how to create an infrared heart sensor using an Arduino controller, a couple of resistors, and an infrared light emitter and detector. This device will be used on the subject's finger, detecting the amount of blood which is flowing through the subject's finger. The amount of oxygenation of the blood is shown in the finger, which will cause the infrared light to reflect off the skin and to the transmitter which is close by. The fluctuations of oxygenation are picked up by the ...
