You can show off your mobile photos and your phone hack savvy by turning your smartphone into an inexpensive projector.
It’s alive! Hack your My Keepon toy into a low-cost animatronic puppet with many of the same functions as Keepon Pro. We'll show you how to connect an Arduino to My Keepon’s electronics, so you can control it using just about any sensors, devices, and interfaces you can imagine, wired or wireless.
This project uses the Seeed Studio GPRS/GSM v2.0 Shield to build a versatile Arduino-based remote alarm system that can notify your cell phone within seconds, via text message, when nearby doors or windows are opened or closed, pressure sensors depressed, or motion sensors activated, just to name a few of the many possibilities. Here we'll teach you how to connect simple motion, touch, pressure, and light sensors, and how to program the Arduino to use the shield to send text messages when these detect events. It's easy to adapt this system to use other sensor devices like temperature probes, magnetic switches, tilt sensors, etc.
Some 3D printing software is easier to learn than others.
In most workshops space is limited.
The light-up shoes from your childhood are all grown up — these Luminous Lowtops are force-sensitive, full-color LED light-up shoes for adults. Each shoe has two embedded force-sensitive resistors (FSRs) — one under the heel and one under the ball of the foot — and up to 40 RGB LEDs that change color based on the FSR readings, giving brilliant visual effects when you walk, stomp, jump, or lean. And a mini Arduino runs the show, so you can imagine the possibilities for customizing the code!
This guide will show you how to build the Vector Weapon Enclosure (which is the default add-on to our Vector Weapon Kit in the Maker Shed).
Build yourself a star in a jar.
Build an Arduino clone using the MintDuino and then program it to visualize your heartbeat in combination with the Pulse Sensor AMPed. The five LEDs mounted to the lid of the tin will flash in sync with your heartbeat's rhythm. Does your heartbeat speed up when you don't tell the truth? When you play video games? When you meditate, can you slow your heartbeat down? Build the Beatband Sleeve and find out!
The MintDuino kit is a fantastic project to help you learn the basic circuitry of an Arduino clone, but it is not mechanically sturdy enough for most projects. This breadboard-to-perfboard project will provide a solution to make your MintDuino as strong as the tin it comes in! Plus, this board layout even allows a 9V battery to fit in the tin alongside the perfboard MintDuino.
Use household materials and simple electrolysis to make metal oxide powders for tinting paints and inks.
Make a better lamp timer that actually knows when it's dark outside, as well as, of course, knowing what time it is. Another smart project from Charles Platt, from his MAKE series Electronics Fun and Fundamentals.
