Fresh hacks every day
This pulse oximeter turned out very nicely. It is based around a Freescale microcontroller and detects pulse as well as oxygen saturation in your blood. The sensor is made of two wood pieces and allows two wavelengths of light to be shined through your finger. A sensor picks up the light on the other side of your stubby digit and … Read the rest
[Mike] is building his own Pulse Oximeter which uses light to measure the oxygen saturation in blood. One collateral benefit of this measurement is that pulse rate can be calculated from the same data. The parts used for the detector include a red LED, infrared LED, and a TSL230R light intensity measuring chip. As explained in the video above, each … Read the rest
We’re skeptical about most technology that’s designed to help remote villages (yes, even that one), but these new UAV medical couriers look like a great idea. The turn around time for medical sample analysis in remote South African villages can be excruciating. A team of engineers have attempted to adapt two different unmanned aerial vehicles for transport of … Read the rest
