Collaborate Disseminate
We’ve seen a lot of environmental monitoring projects here at Hackaday. Seriously, a lot. They usually take the form of a microcontroller, a couple sensors, and maybe a 3D printed …read more Continue reading Jigglypuff Sensor Breathes CO2 So You Don’t Have To
Controlling your computer with a wave of the hand seems like something from science fiction, and for good reason. From Minority Report to Iron Man, we’ve seen plenty of famous …read more Continue reading Low-Cost Computer Gesture Control with an I2C Sensor
Most projects that interface with the real world need some sort of input device. Obviously this article is being written from a standardized “human interface device” but when the computers …read more Continue reading Capacitive Touch Controller for FPGAs
New research from the Technical University of Munich has found remote monitoring of COVID-19 patients can effectively identify the earliest stages of deterioration and admit them to hospital for necessary treatment. The system uses an in-ear sensor to … Continue reading In-ear sensor successfully monitors high-risk COVID-19 patients at home
For those of us old enough to remember the VCR (and the difficulty of programming one), the ubiquitous vacuum fluorescent display, or VFD, is burned into our memories, mostly because …read more Continue reading Using Arduinos To Drive Undocumented Displays
Engineers at Northwestern University have given microchips a new ability – the power of flight. Inspired by wind-dispersed seeds, these “microfliers” are shaped like tiny propellers to catch the wind, and may be the smallest flying structures ever made… Continue reading Helicopter-shaped microchip is smallest flying structure ever built
Typically, detecting glyphosate — a herbicide — in a beverage requires a sophisticated test setup. But Washington State University has a 3D printed sensor that uses nanotubes to simplify the …read more Continue reading 3D Printed Sensor Detects Glyphosate
If you’ve got a mechatronic project in mind, a 3D printer can be a big help. Gears, levers, adapters, enclosures — if you can dream it up, a 3D printer …read more Continue reading 3D-Printing Complex Sensors and Controls with Metamaterials
Remember when work meetings were just a bunch of people filling up a small, poorly ventilated room with their exhaled breath? Back in the good old days, all you had …read more Continue reading Compact Sensor Keeps You Safe by Watching CO2 Levels
While the impulse to solving problems in complex systems is often to grab a microcontroller and some sensors to automate the problem away, interfacing with the real world is often …read more Continue reading Occam’s Razor: Gardening Edition
