Happy Wednesday, #makercamp ! We’ve got a couple cool projects today, and an amazing Hangout later.
The first project is a breeze, and it’s a great little electronics lesson. Plus, it’ll look cool on your porch! We call it a Wind-Triggered Lantern, and it has an LED that lights up on windy days.
The lantern isn’t much more than an LED, a small battery, a feather, and a spring. When the feather moves in the wind, it pulls on the spring, which touches the foot of the LED and closes the circuit — which equals light!
Here’s what you’ll need:
- Soldering iron, and solder, or tape (1)
- Battery holder, (optional) (1) but recommended
- Wire, strong (1)
- Knife, carpet (1)
- Thread (1)
- Feather (1)
- Something springy made of metal (1)
- Battery, 3V button (1)
- LED (1)
- Jar, glass, with lid (1) for weather protection
Alright, follow the photo instructions below and let’s get to work!
And for you expert makers, try this project: A headband that lights up to the rhythm of your heartbeat! http://goo.gl/Jaiku
Don’t forget to tune in today at 11AM Pacific for a Hangout with one of the coolest makers on the planet: from Google X Lab. Mary Lou will be showing us how to make DIY holograms with silver halide and a darkroom, and talking about some of the cool projects she works on.
Until then, good luck with those lanterns!
These images were collected as part of an ongoing joint mission between the USGS and NASA called Landsat. Their satellites have been observing earth from space since the 1970s. Using Google Earth Engine technology, we sifted through 909 terabytes of data to make this historic archive of earth imagery available online.
