Arduino-controlled prosthetic hand operates on verbal commands

Posted on by Leave a comment

Here is a really cool instructable about making a prosthetic hand cum arm that operates on voice commands. The project uses a modified version of the InMoov hand/forearm to construct a five-finger prosthetic hand, which is controlled by an Arduino Uno along with a voice-recognition shield. This hand can perform 15 general hand gestures and actions that are used in daily life, such as pinch, peace, thumbs up, point, etc.

Data recovery from a dead SD card using Arduino

Posted on by Leave a comment

A Secure Digital (SD) memory card is the most standard memory card for use in mobile electronic devices, such as cell phones, digital cameras, GPS devices, and tablet computers. Communication with an SD card can be done in one of two modes: the SDIO mode and the SPI mode. By default, the SD card operates in the SD mode, which is much faster than the SPI mode and is thus more preferable in the portable devices for achieving high-speed data transfer. If you have a damaged SD card that contains valuable information, this example shows you might have a chance to retrieve most of your data through an SPI interface using an Arduino board.

Personal space invader alarm bow tie

Posted on by Leave a comment

We all have an invisible boundary around our body, which we call personal space. We certainly don’t like anybody piercing through this boundary. This personal space defender bow tie is a simple and elegant way to defend your personal space bubble from being invaded by close talkers. When somebody gets too close to you it flashes red lights for a few seconds. If the invader stays there, the lights keep flashing. The project uses FLORA, an Arduino -compatible wearable microcontroller board from Adafruit.

Shoe-integrated sensor system to serve as a walking aid for visually impaired people

Posted on by 2 comments

This shoe-integrated sensor system is supposed to serve as a walking aid for a person with impaired sight. It alerts the user about obstacles surrounding him. Based on the information received from multiple ultrasonic sensors attached to the shoes, an Arduino Mega 2560 board used in the project forms a virtual map of the surroundings. The user is alerted about any obstacle through a set of vibrating elements placed in the user’s trouser pockets.

Desk panic button to get rid of annoying coworkers

Posted on by Leave a comment

Workplace is a jumble of many different personalities and we all find some difficult people to deal with. If you are often annoyed by your coworkers who just walk over to your desk and rope you into long conversations that never end when you’re on deadline, Randy Sarafon’s (from Instruclables) desk panic button will help you get rid of them without hurting their feelings. Unlike other panic buttons, this one does not summon for help in emergency. The idea is when it is pressed it calls your own phone so that you can tell your coworker that you need to answer to this very important call and he may leave. The key components to build this desk panic button are an Arduino board, a GPRS shield and a sim card.
