It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and …read more Continue reading A Lightweight Balloon Tracker For High Altitude Missions
Usually, when you need to sense something in a project, the answers are straightforward. Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s …read more Continue reading Why Use a Sensor When a Pseudo-Sensor Will Do?
The Marimbatron is [Leo Kuipers] ‘s final project as part of the MIT “Fabacademy program” supervised by [Prof. Neil Gershenfeld] of the Center for Bits and Atoms. The course aims …read more Continue reading Marimbatron: A Digital Marimba Prototyping Project
Bed sensors do sort of sound like a gimmick — after all, who cares whether someone is occupying the bed? But if you think about it, that information is quite …read more Continue reading Bed Sensors Do More Than You’d Think
[Jcparkyn] clearly had an interesting topic for their thesis project, and was conscientious enough to write up a chunk of it and release it to the wild. The project in …read more Continue reading D-POINT: A Digital Pen with Optical-Inertial Tracking
We often write a post and then learn something new and cool from the comments. The same thing happened when [Andreas] posted a video about monitoring fluid levels. Commenters told …read more Continue reading Blood Pressure Cuff Hacked into Water Level Sensor
While humans have done a pretty good job of figuring out how to fly with various mechanical contrivances, the fact remains that our natural senses aren’t really well suited to …read more Continue reading Arduino Variometer in a Mint Tin
How do you know if your 3D printer bed is levelled? Oh, don’t worry – you’ll know. Without a level bed, filament won’t stick properly to the build surface and you’ll run into all sorts of other problems. Knowing how tricky it can be to get the bed just right, …read more
