No longer will you have to pay hundreds of dollars for a heart rate monitor! The Smart Heart Monitor will be able to do all of your cardiac measuring needs for you! The Smart Heart Monitor measures the user’s heartbeat using an LED and a very sensitive photo-resistor attached to the user’s ear. A light …
I saw the Open Hardware Pulse Sensor at thought I’d try to make it at home. Took me awhile, but here’s my bumbling process. Step 1: Pulse Sensor — Overview I’ve been working on re-making the the Open Hardware Pulse Sensor so it’d be “easy” to send off to OSHPark and make at home. I’m not sure but I …
Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand and …
Have you ever felt like not wanting to celebrate Halloween? Or too lazy to open the door and hear “trick or treat” a thousand times? Well, if that’s you, we offer the perfect solution without losing the spirit! This project is an automatic machine that works as a candy dispenser by detecting when a hand …
This is a project I’m calling Tacit. No, I didn’t bother making an awkward backronym for it, it just seemed like an appropriate name that’s a lot shorter (though less descriptive) than “Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Asstance Device”. It measures the distance to things and translates that into pressure on the wrist. It’s wrist mounted and senses objects from about …
In this project you can cover your eyes and let your smartphone navigate you to avoid obstacles, the application is mainly a DIY navigation device for blind people. I knew that 1Sheeld is about to launch a new text to speech shield, and so I contacted them to let me use it in this project and they …

Introduction Our goal was to build a brain-computer interface using an AVR microcontroller. We decided that the least invasive way of measuring brain waves would be using electroencephalography (EEG) to record microvolt-range potential differences across locations on the user’s scalp. In order to accomplish this, we constructed a two-stage amplification and filtering circuit. Moreover, we …
Technologies for rudimentary physiological sensing are getting cheaper and easier to implement. Consider, for instance, these non-contact sensors from UCSD which can be used to take an EEG through hair or an ECG through a T-shirt! One can even make a simple oscilloscope to digitize, store and view the signal using only a Tiny45 micro-controller and a …

My partner and I wanted to make heart rate monitor that does more than simply measure a user’s heart rate. Our heart rate monitor talks! Each button gives a verbal description of its functionality and makes the measurements visible on the screen. This monitor will save the last four readings, display them, average them, and …
Introduction and Overview Biomedical engineering, a highly interdisciplinary field within STEM, offers opportunities for engineering and computer science students to engage in its endeavors. It involves the application of biology and engineering principles to create novel devices aimed at enhancing healthcare and medical options. Prominent examples of biomedical devices encompass artificial organs, prosthetics, wearables, and …
