Description It's the end of the world, and you need a button to press. This is it. A red economy grade 100mm diameter (outside diameter) dome illuminated push button comes with an LED, securing nut and a long life horizontal microswitch....

This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

Description : This ANT500 is a telescopic antenna designed for operation from 75 MHz to 1 GHz with a total length that is configurable from 20 cm to 88 cm long. Each ANT500 is constructed of stainless steel and features an SMA male...

The RTL-SDR BLOG V3 is a low-cost software defined radio USB dongle. Perfect for getting into projects that utilize software defined radios or just learning more about them. The RTL-SDR Blog V3 is an improved RTL-SDR dongle. RTL-SDR...

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates...

The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight,...

A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible. The nice thing about LiPower is the ability to use rechargable Lithium Polymer batteries. These batteries are smaller, flatter,...

The MPR121QR2 is an I 2 C driven capacitive touch sensor controller, capable of managing up to twelve electrodes. The chip also has eight LED driving pins, which, when not configured to control electrodes, can be used to drive LEDs. The...

The LPR5150AL is low-power two-axis micromachined gyroscope able to measure angular rate along the pitch and roll axes. All required electronics are integrated onto a single chip with the sensor. The LPR5150AL has a full scale of ±1500...

The KTA-223 Relay Board is a USB or RS485 controlled module that can interface a PC to eight or more SPDT relays. This could be very useful for controlling real world devices - such as lights and sprinkler systems - and reading sensors...

This is a thermal printer like you would find on a cash register or adding machine. It will print simple strings passed to it via TTL serial, bitmap images (poorly) and it even generates several different formats of barcodes! The thermal...

This non-contact infrared thermometer makes it a breeze to take quick and accurate surface temperature readings without getting too close for comfort. Laser sighting ensures that you’re pointing at the right spot: Simply pull the trigger...
