Visualize Your Heartbeat With This Homemade Pulse Sensor
Infrared Pulse Sensor is the latest addition to our beginner-friendly series of Weekend Projects. Inspired by a photoresistor pulse sensor, MAKE’s Technical Editor Sean Michael Ragan built this IR-based pulse sensor using emitter and detector diodes, combined with an LM384 op-amp IC and an Arduino.
The Raspberry Rover
The Raspberry Rover is a small RC car with a Raspberry Pi for a brain. It is controlled over a Wi-Fi network through a TCP/IP socket, and streams back live video from an on-board webcam. It even sports ‘Night Vision’ for navigation in the dark.
Dodecaudion, a Gesture-Based Spatial Music Generator
Dodecaudion is a gesture-based, spatial interface that allows performers to create music by moving hands or other body parts around the 12-sided structure.
Jamming on Lightwaves in this Weekend Project
Build an optical guitar using a common LM386 audio amp chip.
How-To: Mod a Point-and-Shoot for Infrared Photography
Digital camera sensors are typically sensitive to infrared light, but camera manufacturers install a infrared cut-off filter to block these wavelengths. If you have an old Canon point and shoot camera and want to try out infrared photography, Matthew Petroff has posted a guide to modding a Canon PowerShot SD400 for this technique.
Enough Already: The Arduino Solution to Overexposed Celebs
I don’t know about you, but I’m a little sick of hearing about the same people on TV over and over again. I came up with this Arduino-based solution to mute my TV so that I don’t have to hear about Donald Trump’s feud with whomever or Charlie Sheen’s most recent rant. Using the Video […]
