Scientific Research High Altitude Balloon for Fun and Profit. High-altitude balloons are unmanned balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between 60,000 to 120,000 feet (11 to 23 mi; 18 to 37 km). Such a flight allows for the collection of an enormous amount of interesting scientific data. For our balloon, we chose to measure Barometric Pressure, Relative Humidity, Temperature, Battery level Voltage (to see the effects of temperature on battery life), Altitude, and Radiation (measured in CPM, count per minute). Out of all of these measurements, we found radiation to be the most interesting, as there was a HUGE difference in the radiological readings obtained on the ground versus those taken as the balloon increased in altitude. Finally, we also took 1080p video of the flight, using a GoPro HERO 4, which provided some amazing footage of earth from near-space altitudes.

Robo-Mobile - A Homemade Bluetooth Robot. Background This robot is one I built to learn. Before this project I did get my feet wet with a few small scale Arduino projects like an ultrasonic robot, (that would move backwards until it was a certain distance away from the wall,) and I did get to play with a few of the shields designed for the Arduino, but I had never built a full scale project with this microchip, or really, any microchip. I knew if I was going to continue on this journey of being a hobbyist I would have to fully understand the Arduino inside out.

I wanted a project that would accomplish my goal, (or just get closer to my goal of fully understanding the Arduino,) and one that would be useful or fun to play with after completion! The project that would help me do just that was the Robo-Mobile. Overview The Robo-Mobile consists of two parts: a chassis and a robotic arm. Contests There are many contests that I have entered this Instructable in.

Rechargeable LED Illuminated NightShoe. An Absolute Beginners Guide To The Intel Edison. Hey there! I recently received an Intel Edison board from Instructables, as a nice gift. If your wondering what that is, the Intel Edison is a tiny computer the size of an SD card (that's seriously small), for electronics and computer hobbyists out there. It has dual-core Atom CPU, and includes WiFi and Bluetooth in one heck of a tiny package. The Edison goes well with its breakout board (which I used), as it makes it easier to program and use.

It runs Linux, and supports Arduino, Python, Node.js and other programming languages as well. The Edison is made specifically for IoT (Internet of Things) projects, and also wearables, taking advantage of its size.

The Edison is a fully-fledged computer. So let's begin! Tableau de bord Intel IdO Analytics. 3D Printer. Compact Arduino GPS Speedo + and more. Sound Localization using Arduino -Use Arduino for Projects. Well, it’s elementary simple in theory, how to do sound localization based on phase difference of signals, that received by two spatially distant microphones.

The Devil, as always, in details. I’ve not seen any such project created for arduino, and get curious if it’s possible at all. Long story short, here I’d like to present my project, which answer this question - YES! Let me stress, project based on phase delay, not TDOA. Measurements results show, that current version of software (both copy of the source code, linked below, they differ only in filtering technics) has minimum detectable phase offset 1 degree!!!

This gives astonishing special resolution.

Major Components in Project Arduino For more detail: Sound Localization using Arduino. Get your fingerprint. Finger tambour sans fil. I came across these Force Sensitive Resistors. I like them a lot and I wanted to do something with them, may be making them more usesable than standing on the breadboard. Few months ago, I created the pocket-sized RevIO - Arduino Compatible and having fun with it since then. While playing with these two, I decided to put them together! To complicate things further, I wanted to use them wirelessly. So I added XBee module to send commands wirelessly from RevIO to play different drum sound snippets on the PC speakers.

Above was not the only reason to make me put these four force sensitive resistors onto the RevIO case permanently. This instructable only shows how to use these FSRs to make drum sounds as they are pressed. Here is the video when I tested them. Fingerprint Scanning doorlock with access history printer.

Mini Thermal Receipt Printer Starter Pack ID: 600 - $61.95 : Adafruit Industries, Unique & fun DIY electronics and kits. Lecteur d'empreintes digitales - 5V TTL (GT-511C1R) - SEN-13007. Description: Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they’re usually unreliable or difficult to implement. Well not anymore! We’ve found this great fingerprint module from ADH-Tech that communicates over TTL Serial so you can easily embed it into your next project. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an on-board optical sensor and 32-bit CPU.

This is the more economical version of the GT-511 which has a decreased memory capacity (compared to the GT-511C3). The module is small and easy to mount using two mounting tabs on the side of the sensor. Note: The module does not come with a cable, check in the Recommended Products section for an appropriate one. Dimensions: 37 x 17 x 9.5 mm Features: Documents: A compact, Arduino altimeter for RC Planes. Please vote for this Instructable if you think it deserves it! Thanks! The Ultimate Altimeter is a super-compact, Arduino controlled altimeter capable of measuring the altitude with an accuracy of 0.3 meters, and saving the highest and lowest values it has measured.

It is powered by a 40 mAh Lithium Polymer battery, uses a tiny LCD Bubble Display, and measures altitude with a MPL3115A2 Altitude Sensor. It's very simple and fairly easy to build with just six major components. The Altimeter has a couple of different modes: current altitude, highest altitude, lowest altitude, difference in altitude (highest minus lowest), and standby (turns display off to save power for ~6 hr battery life, not shown in video). The entire build adds up to around $30, but you may have some or most of the parts lying around already.

You can make this! Home Automation/ Control a Relay with your Parallel Port. This is my version of controlling external devices with your computer. Namely with the LPT or parallel port. The software is from Lalim, version 3.0.6. The patent was no longer valid scenes 2009 and the direct link to this controller is no longer working. You can get to a Lalim software company, but not for this program. So where did i get it? From the endless hours of research i do online i just found it. But do not worrie i have it available for download. This program does a lot more than i use it for. As with most of the stuff i build it is rarely all from one place. This method does take a lot of wiring. ****** This Instructable uses 220 AC so take extra procation when working with mains ****** How to hack digital Infra Red switch to make analogic IR distance sensor. Using Servos with Arduino made easy ! Servomotors or simply servos are essential components of a robot which convert electrical energy into mechanical energy.They are widely used in the field of RC hobby and robotics.

But unlike simple geared motors , these servos are made by integrating a geared motor with a position feedback circuit which allows us to control the rotation of the shaft precisely. To drive a servo , we need a controller which provides PWM signals to the servo which in turn determines the angle of rotation. Using an arduino to do this is pretty easy job, all you need is : 1. A servo ( To make your own servo , check this out : make your own servo ! 2. 3. 4. 5. How to Use a Servo with Tessel. Hacking my RC Car using Arduino and Android Smart Phone.
