Almost Anything Can Be A Touch Input with The Touch Board and Electric Paint

Bare Conductive, a British startup, has designed an Arduino Leonardo compatible board with 12 capacitive touch sensors called the Touch Board. You can basically use any conductive material as a touch sensor, but the company’s existing “electric paint” really makes the board come to life, and you can just draw circuit anywhere, be it on paper, your wall, cardboard, and create fun and useful applications. Touch Board specifications: MCU – Atmel ATMega32U4 Microprocessor @ 16 MHz with 32 KB of Flash Memory of which 4 KB is used for bootloader. External storage – MicroSD card slot I/Os: 20 digital I/O pins (3 used for Touch IC and 5 for MP3 IC – can be disabled) 7 PWM channels 12 analog input channels 12 Touch electrodes of which 8 can be configured as extra digital inputs or outputs with PWM capability. (via Freescale MPR121) Audio – Playback and MIDI support via […]

The VERVE Connects Sensors Your Computer for Gaming, Monitoring, and More

The VERVE is a little box that connects to one of the USB port of your Windows or Mac OS X computer (Linux support coming in 2014), and supports up to 7 sensors. It is available as part of a kit for $99 on Kickstarter. The kit includes the VERVE, a mini USB to USB cable, seven “sensors” (A force sensor, a push button, a light sensor, a potentiometer, a motion sensor, a magnet sensor, and a touch sensor), two banana clips for the touch sensor, seven cables to connect the sensors to the VERVE unit, and 5 extension blocks. Once the VERVE unit is connected to your computer, and the needed sensors are connected to the VERVE, you can launch the VERVE application to visualize the sensors data in real-time, and assign a mouse or keyboard action based on the sensor’s data level as shown below. There’s also an […]

Scanadu Scout Medical Tricorder for Android and iOS

Low cost personal medical tricorders have the potential to dramatically bring down the cost of health care, and avoid unnecessarily wasted time in hospitals, which is probably the XPRIZE Foundation has launched a competition for  medical tricorders, where the winners will get 10 millions US dollars in funding. Scanadu Scout is one of the entry, and they currently have an indiegogo campaign, already oversubscribed, for their medical grade tricorder which gather data by placing it on your forehead for 10 seconds, and display medical data transferred via Bluetopoth Low Energy (Bluetooth SMART) on your iOS and smartphone. The company did not disclose full specifications, but they still revealed the device runs 32-bit Micrium RTOS, which is already FDA approved (pre-market 510K notification and PMA approval), it supports Bluetooth 4.0 SMART, and a micro USB port is included to recharge the battery. I fired up few Google image searches to look […]

$25 Texas Instruments SensorTag is a Bluetooth LE Devkit with 6 Sensors

Yesterday, I wrote about Wimoto Motes, tiny Bluetooth LE devices with several sensors that can be controlled and monitored via an iOS app, and soon by an Android app, as well as Linux devices. Each mote costs $39 plus shipping, and one commenter mentioned the price may be a bit too high. A Google search for “bluetooth sensor” immediately brings TI SensorTag, which looks somewhat similar, except it is a Bluetooth LE development kit, includes 6 sensors (but no light sensor), and only costs $25 including shipping. SensorTag Specifications: Bluetooth 4.0 low energy (CC2541) SoC 6 sensors connected via I2C: IR Temperature sensor (TI TMP006) Humidity sensor (Sensirion SHT21) Pressure sensor (Epcos T5400) Accelerometer (Kionix KXTJ9) Gyroscope (InvenSense IMU-3000) Magnetometer (Freescale MAG3110) Power – Single cell coin cell battery (CR2032), quiescent current consumption of 8uA, allowing years of battery life. FCC, IC and ETSI certified solution Dimension – 71.2x36x15.5 mm, […]

Wimoto Motes are Tiny Bluetooth Sensors for iOS, Android, and Linux Devices

Wimoto Motes are small (30x30x8mm) wireless sensors that communicate temperature, humidity, soil moisture… values to your iPhone, iPad, Android, and Linux (yes, including the Raspberry Pi) devices via Bluetooth. They are said to last for about a year on a single CR2032 battery and don’t require an Internet connection to work, but you can still upload your data to Wimoto cloud service via the app, or use an optional mote.cloud bridge to do it for you in realtime via Wifi. There are currently 4 Motes: Climote – Measures light (0 to 60,000 lux), temperature (-25 to 85 C) and humidity. Used to monitor a room environment (bedroom, cellar, greenhouse,…), and tell you if you need to make adjustment Growmote – Measures sunlight (0 to 60,000 lux), soil moisture (5 levels) and temperature (-25 to 85 C), to make sure your lawn or flowers are not  thirsty. Thermote – Measures an object temperature […]

Le Labo Citoyen Gasser – Raspberry Pi Based High Precision Pollution Monitoring System

“Le Labo Citoyen” is a recently founded French non-profit organization aimed at “promoting and experimenting with innovating and free technologies for the citizens and the environment”.  Their first project is to gather pollution data (NO2, O3, and SO2 levels) in Paris using 2 (soon to be) open source components: Gasser – Self-contained mobile sensor currently powered by the Raspberry Pi ThingStream – Open source IoT datastore which should be similar to iDigi Cloud, except you can just store data in your own server or on “Le Labo Citoyen” servers. Gasser has four main parts: Sensor(s) – Alphasense B4-series sensors (black and red component in the top left of the  main box) with accuracy of up to <10 ppb (parts-per-billion). Cost: ~110 Euros. They currently only use the NO2 (nitrogen dioxide) sensor. ADC & Computer – Raspberry Pi (Cost: ~30 Euros) & Delta-Sigma ADC (Cost: ~30 Euros). Communication Medium – Huawei […]
