Here is a demo video:   This project was build based on idea on how to make a simple and cheap online surveillance camera robot that everyone can build. Not only that the robot also have to be easy to use and maintain. Using the raspberry pi, few cheap components, a robot chassis/RC car, and webiopi tutorial on the MagPi magazine this project was successfully build. For launching this robot to be accessible online, ngrok service from www.ngrok.com is used. Without any hectic and difficult port forwarding configuration this robot now can be controlled from anyone in the world by just using firefox or chrome browser.   No soldering is required to build this robot because I use jumper wire to connect all necessary connection between the GPIO to the L298n motor driver module, and then i connect the two dc motor to the mounting hole on the L298n module.

Head mounted displays are definitely the latest fad that’s going around town now. You might have seen several wearable displays such as the google glass, and many others including virtual reality systems like the oculus rift. Head mounted displays are primarily used for video sharing, navigation, checking notifications, etc. However, several pioneers argue that the quintessential use for it have not yet been identified. But, if you ever wanted to build one for yourself from scratch, and are not willing to pay 1500$ just to experience its functionalities, then this DIY Head Mounted Display project is for you. This DIY hacking tutorial will show you how you can make your own head mounted , virtual reality or augmented reality displays. I have built a “Smart Cap” , first of its kind , having a head mounted display on it. Here, I will instruct on how to build a monocular wearable display that runs on the raspberry pi as seen in the picture above. The syst...

Key Features (At a Glance) - A.I Home Automation - Energy Savings Efficiency - Voice Recognition and Speech Synthesis - Enhanced Security and Safety - Entire House Wide Virtual Assistant - Sleep Pattern Tracking - World Wide Web Enabled Home Automation - Custom Android Application and Computer Software - Low Cost (Under $200) - Research Report Compilation, Question Answering (Including mathematical equations) - Any hacked appliance or device can work with this system Jarvis In-Depth Intelligent Automation Jarvis is the name of Iron Man's computer system which manages his home, hence the name of this project. The main aspect of Project Jarvis is to help save electricity in your home which then helps save the Earth and of course, helps save a bit more money each month. The electricity usage is logged per room into an SD card on an open source micro controller such as an Arduino or Raspberry Pi, I chose Arduino. The code on the MCU then interacts with a larger...

The Internet Controlled RC Car allows you to remotely drive around a small rc car from wherever you may be and see where it is going. This is fun because you can remote explore whatever space you leave it in, or hand over the keys - so to speak - and allow someone to drive around your space. This is also a great building block for a telepresence robot. This project is also a great beginner project for someone who has made a few simple things and is looking to get slightly deeper into the world of microcontrollers. It starts to incorporate more advanced skills like circuit building and networking, but is not dauntingly complex. Read More

Hello everyone! As the title says, I built an electric go kart which is powered by arduino! Here's a quick video to make you certain that this is the next thing you're going to build. http://tinypic.com/player.php?v=w8x2s9&s=8 (Sorry, the embedding isn't working for some reason) My background: I'm a 15 year old high school student from California. My hobbies include building stuff, reading, and studying Japanese. I've also entered into the Epilog Challenge contest, please vote for me! A quick disclaimer: I take no responsibility for any injuries to yourself or anyone else. Electricity is DANGEROUS. Chain drives are EVEN MORE DANGEROUS. They could easily cut a finger off or worse. Wear a helmet when attempting things like this. With that out of the way :) Overview: The drive setup uses a Hobbywing Xerun 150A brushless electronic speed controller to control a Savox BSM5065 450Kv motor. Batteries are 3x zippy lithium polymer - 5 cell...

This “Gamegirl” 3D printed Gameboy replica by Adafruit features some seriously upgraded hardware to mark the original’s 25th anniversary. The Raspberry Pi processor allows it to run Gameboy, or even MAME ROMs, and the color touchscreen allows for much better graphics than the original’s grayscale display. Adding to these significant upgrades, the built-in rechargeable battery is a welcome addition. Those that had these devices likely remember buying battery after battery to keep playing Tetris or SolarStriker. The case is 3D printed, and aside from the varied colors, it could be mistaken for an original Gameboy; at least it appears that way from the video. Aside from the printed parts, the gamepad buttons are recycled from a Super Nintendo controller, so there is some disassembly and cutting involved. Quite a few more components are also needed from Adafruit, but the instructions seem to lay everything out nicely. If “merely” playing ROMs isn’t good enough for you...

HAB (High Altitude Ballooning) is a growing hobby where enthusiasts use standard weather balloons to put small payloads typically 100g-1kg into “near space” at altitudes of around 30km or so, carrying a tracking device (so the balloon position is known throughout the flight) and usually some sensors (temperature, pressure etc) and often a video or stills camera storing to an SD card for later retrieval. The job of the tracker is to read the location from the GPS receiver, possibly also read some sensors, and then format and send a telemetry sentence to the ground over a low power radio link. Flights only happen once the predicted path is known to be safe (avoiding airports and densely populated areas for example) and permission has been gained from (in the UK) the CAA. Here the tracking system uses the 70cm radio band (around 434MHz) using RTTY to send the telemetry down to a number of ground stations run by other enthusiasts. Telemetry from all receivers is sent to a ce...

Dave Hunt ‘s been at it again. Here’s his latest: a home-made smartphone based around a Raspberry Pi. It’s smaller than many of the phones I’ve owned, and it’s cheaper than the phone that’s currently in my pocket, with a parts list coming in at only $158. The PiPhone is built entirely from off-the-shelf kit, so there’s no soldering required, and no fiddly electronics work. I’ll let Dave introduce it to you. PiPhone: A DIY Raspberry Pi Cellphone

The Internet of Things  makes it easy for us to monitor our homes. Today I’m taking that concept one step further—getting our homes to report back to us.  In early March, I wrote about  using Raspberry Pi to quantify my fish tank —in short, I taught the $35 single-board computer to monitor the temperature of my home aquarium no matter where I was in the apartment. Of course, the limitations of this project were clear: I could only keep tabs on the tank while on my home network. What if I want my fish to text me when it needs my assistance?  The problem, until now, was that getting the Raspberry Pi to initiate communication was hard. I experimented with a  Node.js receiving application, and contemplated buying a server from which to run it (since my Bluehost server space doesn’t support a Node installation). The other way to get the Raspberry Pi to talk to me was to teach it to text my phone. There are also  many ways to achieve SMS support ...
