DIY wireless data transceiver
Build your own wireless transceiver: Have you ever wanted to send data from a sensor or project wirelessly? This simple circuit allows you to build your own wireless transceiver using two ICs, a transistor, and two resistors. The IC is from Melexis and uses On-Off Keying modulation and can be battery powered. Via Electronics Lab.
OpenduinoGSM
Emanuele has informed us of a new open source project known as OpenduinoGSM. This is a standalone wireless remote control board which communicates via GSM. With OpenduinoGSM you have the option of using the Arduino development environment, so anyone, even those who are unfamiliar electronics and circuits, can try to realize the automation they want […]
Microchip’s BodyCom technology
BodyCom™ Technology provides a secure communication channel using the human body: Microchip’s BodyCom™ Technology is a short-range, low-data-rate communication solution for securely connecting to a wide range of wireless applications. Activated by capacitively coupling to the human body, the system communicates bidirectionally between a centralized controller and one or more wireless mobile units. Intra-body communication […]
Better BBQ with Flyport and Cosm
Here’s a video demonstrating how to keep your BBQ under control using COSM and Flyport Wi-Fi: Michael Posavec, a strong supporter of openPicus, decided to hack his Maverick wireless BBQ thermometer adding Flyport Wi-Fi to make it Internet connected.
Controlling Arduino via Android mobile device
Kerimil over at Arduino forum posted this simple how to on controlling an Arduino board with an Android mobile device. He describes, “The circuit is just a Bluetooth module, Arduino UNO, LED, resistor and some wires. The LED can be switched on using buttons as well as voice activation (anything that contains the word ‘on’,’off’ […]
New TI CC3000 modules
video platformvideo managementvideo solutionsvideo player TI has announced the availability of their new CC3000 module. The TI CC3000 module is a self-contained wireless network processor that simplifies the implementation of Internet connectivity. The module uses TI’s SimpleLink WiFi solution which minimizes the software requirements of the host MCU. TI has posted information on the BoosterPack, […]
How to use Nokia F-bus to send an SMS message
If you have an old Nokia phone and want to hack it to send SMS messages, this tutorial by Alex at InsideGadgets should prove interesting. He’s produced a detailed tutorial showing the hardware and code needed to interface a Nokia 6110-series with an Arduino Duemilanove to send SMS messages. The Arduino connects to the phones […]
Corpsman Up vitals monitor using Propeller chip
Here’s a project for remote monitoring of heart rate (and potentially other medical/sensor info) using Propeller chips and XBee modules. Nick Ernst has published his plans and code for the Corpsman Up Vitals Monitoring System on the Parallax website. The system consists of two units: a base which is equipped with a Parallax Propeller MCU […]
Texas Instruments CC3000 integrated WiFi IC
Texas Instruments released the CC3000 integrated WiFi IC. It features on-chip everything needed to connect your project to a WiFi network. TCP/IP stack, configuration utilities, and your security tools are included in the IC. Vince made a breakout board for this IC using Altium Designer. Also available are design files direct from TI for their own evaluation […]
Bluetooth MSP430 tank
Here’s an interesting and fun use of the MSP430 and your Android phone: robotic tank control. This project by Mike adds a Bluetooth transceiver module MSP430 and mounts this along with a motor drive booster pack and battery on a toy tank from Pololu.com. He says, “All in all, a fun project where I learned […]
Tiny TL-WR703N router acts as a wireless USB port
Madox wrote a tutorial on how to setup the cheap TL-WR703N WiFi router to act as a wireless USB port for your Windows computer. This means that any USB device you attach to the router will be recognized by your own computer as if it was pluged into a local USB port. So it has […]
Tweeting cat door
Let your cats be part of the social media explosion! The tweeting cat door project tweets a message every time a cat passes through the door. The project is based around the Electric Imp which is a Cortex M3 processor and a WiFi transmitter packed into an SD card. A breakout board for the Electric […]
DEFCON 20 – NFC Hacking: The Easy Way
Eddie Lee, a security researcher at Blackwing Intelligence, gave this presentation at last Summer’s DEFCON 20 conference. His technique involves using NFCProxy, an open source software tool released at the conference to analyze 13.56 MHz RFID protocols and proxy transactions using Android phones. NFCProxy can view the wireless transmissions from the perspective of the tag […]
TP-Link WR703n as telemetry link and camera broadcasting tutorial
Here is a guide on how to setup the cheap TP-Link WR703n router to act as a telemetry link and an USB camera broadcasting server. The guide is in three parts, starting from flashing the OpenWrt firmware, adding a USB hub and extending the memory with a USB flash drive, and finishes with explaining how […]
How to give your Arduino wireless capability
It seems the Ethernet Shield is unnecessary if you want to connect your Arduino to WiFi via the cheap TP-Link WR703N router. This is due to the fact that the router can be hacked with OpenWrt making it a Linux box with a fully functional USB. For those of us who are not afraid of […]
How to give your Arduino Ethernet shield wireless capability
Connecting your Arduino to the internet is cool, but it’s even cooler to connect over WiFi. Luca explains how to connect your Arduino Ethernet shield to a cheap WiFi router to give it WiFi access. If you want to boost the security and privacy of your home’s wifi network, you may buy residential proxies. Sometimes […]
Pinoccio – An open source wireless hardware and software platform
Bryan pointed us to the Pinoccio. It’s an Arduino compatible Wireless platform. It’s based on the ATMega128rfa1 microcontroller with an 802.15.4 compliant radio built in. It also features a LiPo charger and battery, making it easy to recharge over USB. The project is open source and hosted on github. Via contact form.
TL-WR703N router based WiFi controlled toy robot
