Fresh hacks every day
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
[Markus] recently took his 14-month-old daughter to the pediatrician for a routine checkup. During the examination, the doctor needed to measure her pulse and quickly clamped an infrared heart rate monitor onto her finger. Between the strange device clamped to her finger and incessant beeping of machines, [Markus]‘ daughter got scared and started to cry. [Markus] thought these medical devices … Read the rest
The University of Glasgow has released a Chemistry research paper covering the applicational process of printing pharmaceutical compounds.
Yes thats correct actually printing medication. Using various feedstock of chemicals they see a future where manufacturing your medication from home will be possible. Using standard 3D printing technology it is possible to assemble pre-filled “vessels” in such a way that … Read the rest
[Jordan Miller], [Christopher Chen], and a whole bunch of other researchers at the department of bioengineering at U Penn have figured out a way to print 3D tissues using a 3D printer. In this case, a RepRap modified to print sugar.
Traditional means of constructing living 3D tissues face a problem – in a living body, there’s a whole bunch … Read the rest
Normally, colonoscopies are rather invasive affairs. Swallowing a small pill with a camera is much more amenable to a patient’s dignity and are seeing increasing usage in colon cancer screening. [Mike] acquired a pillcam from a relative who underwent the procedure and did a teardown to figure out how it works.
To get the video signal out of the body, … Read the rest
Here’s something we thought we’d never see on Hackaday. [Chris Suprock] is developing an artificial heart he calls Steel Heart. It’s an artificial heart powered by electromagnets and ferrofluids.
The idea behind [Chris]‘ artificial heart is ingenious in its simplicity. An elastic membrane is stretched across a frame and a magnetic liquid (or ferrofluid, if you prefer) is poured … Read the rest
[Linas] built himself an x-ray generator for a scholarship contest. We assume this wasn’t enough of a challenge for [Linas] because after the x-ray generator was done, he used his project to model objects in 3D (Google Translate link). It’s an amazing build, leaving us feeling sorry for the guy that came in second place to the home-made … Read the rest
