I saw the Open Hardware Pulse Sensor at thought I’d try to make it at home. Took me awhile, but here’s my bumbling process. Step 1: Pulse Sensor — Overview I’ve been working on re-making the the Open Hardware Pulse Sensor so it’d be “easy” to send off to OSHPark and make at home. I’m not sure but I […]
I had been looking for a cheap alternative to some of the Arduino Bluetooth devices I’d seen, which in my opinion are overpriced. Redbear’s Mini: $39.95 (Note: This is a uC and BLE combo). Redbear’s Uno Shield: $29.95 BLEDuino: $19.95 (if part of Kickstarter) Bluegiga Shield: $69.95 After seeing these, I thought I’d try to […]
This project idea came to me when I was sitting on a bed on a hotel room on vacation. I thought: “It’d be really neat to have a robotic hand that I can control with my own hand!” Upon returning home, I embarked upon a journey to design and create the project. I hope you […]
Make a power wheels jeep that is controlled by an XBOX controller. This particular build is using Power Wheels® Jeep® Hurricane with Monster Traction™ but should be usable across many different types of power wheels with small adjustments. I wanted to do this project so I could drive my kids around. They are 2 and 3. We […]
This project is an Arduino-powered infrared touchscreen / coffee-table interface that I’ve been using to control various music and graphics applications on my computer. This is an old project that I’ve recently had time to go back and document/fix up; this project is a little more special to me than most because it was my […]
Story: NASA has taken worms to the ISS on their own special capsule. There was an accident aboard the station and the worm astronauts have to navigate to the escape capsule to return to Earth. The airlock to the escape capsule has been damaged but can be reached from the other side of the ship. […]
There are a number of great Instructables on LED grids out there. This is a low cost version – not quite as polished, but easy to make. This project uses a couple of sheets of foam core, a fluorescent fixture cover from the local home store, a cut up strip of WS2812b LEDs, and an […]
Arduino Powered Micro Aquaponic System with Pi Camera and Twitter Feed We are creating an automated aquaponic system with mobile updates via Twitter. Sensors and motors will be controlled from an Arduino while the entire system, including mobile updates, will be orchestrated by a Raspberry Pi. Tweets include pictures, sensor data, and system-critical updates. Original […]
One Challenge with working with RGB LEDs is getting the right Red, Green and Blue values to match a color you are trying to display. You can start with web colors, and then sometimes need to adjust them since the LEDs don’t look quite the same as they do on monitors. So, this is a […]
Today I’m going to show you how I made my “light painters palette” aka light box. If your into electronics and photography than this is probably something you are going to like. Supplies: -Arduino (I’m using a arduino pro mini which requires a ftdi basic to program, But an uno or leaonardo… would work just fine) –Tri […]
