Use dual LM386 amplifiers to build this portable two-channel bass bump headphone accessory. The amps will give you an added boost of low-frequency spectrum that will immediately change the way you listen to music. It’s battery-powered and rechargeable so you can bump your jams wherever you go.
Join us at the scheduled hangout time to watch LIVE as we talk with Akimitsu “The LED Artist” Sadoi about his LED color organ projects, and demo our own build of his circuit on solderless breadboard.
Use an Arduino, MakerShield, and ethernet shield to build an automatic water dispensing system to fill up your pet’s water bowl while you’re away. The sensors connected to the circuit know when the bowl is low – and filled – with water, and it can even tweet when the reservoir runs out!
Join us TODAY at 3:30pm PT/6:30pm ET for our second Weekend Projects Hangout On Air. We’ll be talking with MAKE Technical Editor Sean Michael Ragan about the Pedal Power Phone Charger, a simple AC-to-DC generator circuit for charging your cell phone (or any other gadget that sips a steady stream of 5VDC) while on the […]
Combine some common components and several pieces of software into one, and assemble this microcontroller-driven motion-sensing camera that records VGA resolution pictures to SD card.
Join us today at 3:30pm PT/6:30pm ET for a quick 20-minute Hangout On Air with Tom Rodgers, maker of the TV-Go-Sleep Universal TV Timer, an Arduino-powered sleep-timer that will turn off any TV in range after a countdown.
MAKE reader Scott recently built a modified version of the IR Pulse Sensor by Sean Ragan by combining it with elements from the original circuit, as designed by Let’s Make Robots user MarkusB.
