Arduino voice control with EasyVR shield
If you want to add voice recognition to your next Arduino project, you might want to consider the EasyVR Shield by VeeaR. It’s based on the EasyVR module, and combined with supporting libraries provides up to 32 user-defined Speaker Dependent triggers (in any language) or commands and voice passwords. The shield makes available three controllable […]
Human birdwings project: the only thing real was the Seeeduino
UPDATED: The Human Birdwings project is an elaborate hoax, the brainchild of possibly one Jarno Smeets, an alleged mechanical engineer from the Netherlands. His stated goal was to build a set of functional human birdwings similar to those conceived by Leonardo Davinci. Tinito was watching the above installment from the 14-video series and discovered that […]
Internet connected camera using Arduino
Our friends at Adafruit have put together a detailed tutorial on construction of your own Internet of Things Camera. They combine the Arduino with their data logger shield outfitted with the Eye-Fi wireless SD card (first gen model) and a TTL Serial JPEG Camera shield. The result is a self-contained wireless monitoring camera with motion-sensing […]
Tiny CNC-bot for under $70
The developers over at Piccolo are working on a CNC-bot designed to draw small pictures, and which could be reprogrammed for other purposes. According to the developers, “We are currently refining the Piccolo prototype into an open-source design that is simple, quick to assemble, and easy to use, and is entirely composed of digitally manufactured […]
PlayStation 2 controller connected over a RFM12 wireless module
Dustin connected his PlayStation 2 to a PC wirelessly using two RFM12 modules to make the link. On both sides AVRs with Arduino bootloaders drive the wireless modules. All the source code for this project is available.
Remote controlled balancing robot using mbed MCU
Kristian Lauszus updates us on this remote controllable balancing robot project. In development of this project, Kristian created the PS3 Bluetooth Library both for Arduino and the FEZ Devices. However, not content with the performance of the FEZ, an mbed microcontroller, which is an ARM Cortex-M3 running 96MHz, has been incorporated into the latest design. […]
PlayStation 2 controller Arduino library
Bill developed an Arduino library for PlayStation 2 controllers: I had to rewrite a lot of code that powers the library, there is not much left of the original code written by Shutter of Arduino forums. There were many bug fixes, now the controller should automatically be in analog mode, and the mode button should […]
Boot your PC with the Arduino using the Wake on Lan command
Luca explains how to boot your PC with a Wake on Lan command sent from an Arduino. Setup the WOL feature on your PC, then use the sendWOL() command to send a magic packet via and ENC28J60 ethernet chip: The wake command is issued sending on the network a specific packet, called Magic Packet. This […]
Arduino WiFi RGB Ikea lamp mod
Open Electronics built an Ikea lamp mod using an Arduino with a WiFi shield, and a custom RGB LED driver shield. The mod allows people to to change the color and intensity of the lamp by accessing it’s web page. The system that we propose is based on the Arduino UNO, on which are mounted […]
Open source HDD POV clock
Jason designed a persistence of vision hard drive clock. He etched numbers on a copper disk and added 8 LEDs below it. Each LED represents a character on the display and blinks when the corresponding digit passes over it. His project is Arduino-based, and the project files can be downloaded from GitHub. My replacement platter was cut […]
BootDrive loads Arduino sketches from an SD card
Kevin wrote an Arduino bootloader that loads sketches from an SD card. BootDrive is open source and available on GitHub. Announcing the formal release of BootDrive for Arduino. If you’ve been reading the blog, you know that I’ve been working with Justin Shaw of Wyolum labs to enable their I2SD (Arduino clone with a micro-sd […]
Transparency Grenade blows WiFi privacy out of water
Created in January, 2012, by Julian Oliver for the Studio Weise7 exhibition at Labor 8, Haus der Kulturen der Welt, Berlin, the Transparency Grenade represents a more physical approach to fostering the process of corporate and government transparency than the slow, tedious process of policy reform. Equipped with a tiny computer, microphone and powerful wireless […]
Maker Shed pulse sensor
The folks over at MAKE have a pulse sensor which attaches to your fingertip or earlobe and measures minute changes in light from expansion of the capillary blood vessels to sense your heartbeat. Technical information is available here, including design files, sample code and schmetic. The device is licensed under the TAPR Open Hardware License. […]
Arduino automatic CQ caller for amateur radio
VK3YE likes to work CW (Morse Code) on the 40-meter band, but doesn’t like the monotony of hand keying CQ endlessly. He devised this simple project using an Arduino to tap out CQ and his call sign automatically at predetermined intervals. The keying was originally accomplished using a reed relay as shown in the video. […]
Giveaway: 4 LeoStick Arduino Leonardo compatible USB sticks
Freetronics’ new LeoStick is an Arduino Leonardo compatible USB board. It’s a simple breakout for the ATmega32U4 microcontroller in small USB stick shape. It has 2 RGB LEDs and a buzzer on-board for experimenting. The LeoStick is just like the upcoming Arduino Leonardo, but given the “honey, I shrunk the kids” treatment! Just pop it […]
Years project uses Arduino to play tree rings
YEARS from Bartholomäus Traubeck on Vimeo. Bartholomaus Traubeck presents his “Years” project. Years is a phonograph-like device which reads the characteristics of the rings in a thin cross-section slice of a tree and interprets these as piano notes depending on the appearance of the wood (ranging from dark to light and from strong texture to […]
DIY MMA7455L 3-axis accelerometer breakout
Here is a DIY breakout board for the MMA7455L, an inexpensive three-axis accelerometer. It’s got all the decoupling capacitors and pull-up resistors specified by the accelerometer datasheet.There’s also an interfacing tutorial for the Arduino. We like this chip because it’s cheap, but the LGA package is difficult to solder. If you’re not up for soldering […]
Tutorial: using Ping ultrasonic sensor with Arduino
Tronixstuff has posted a tutorial explaining how to use the Parallax Ping sensor with Arduino. The Ping is an ultrasonic distance sensor from Parallax which retails or about $30. This segment is the latest in a series of Arduino tutorials posted by Tronixstuff.
New liquidCrystal Arduino library
Francisco Malpartida, an Arduino enthusiast from Spain, has posted a new liquidCrystal library for Arduino. The main differences are a claimed increase in speed of LCD operations and the ability to control the LCD display via an I2C bus expander or a Shift Register Extender in addition to the usual 4- and 8-bit modes. Via […]
