Multichannel time-synchronised mesh networks based on 802.15.4 radios address many of the challenges involved in designing wireless sensor networks, write Lance Doherty, Jonathan Simon and Thomas Watteyne from Linear Technology While both low-power sensors and wireless networking are now ubiquitous, there are still relatively few examples on the market of low-power wireless sensor networks. This […]

Description   The LMH6882 is a high-speed, high-performance programmable differential amplifier. With a bandwidth of 2.4 GHz and high linearity of 42 dBm OIP3, the LMH6882 is suitable for a wide variety of signal conditioning applications. The LMH6882 programmable differential amplifier combines the best of both fully Differential amplifiers and variable gain amplifiers. It offers […]

The specifications for the scope are rather nice: decent bandwidth and sampling rates, a large bright display, a battery option and lots of connectivity such as a USB host, USB device and Ethernet. The scope is pretty crappy in some ways though. The analog section is fairly noisy so don’t expect to see any details […]

Internet of My Own Things Intelligence without ambition is a bird without wings. –Salvador Dali The Internet of Things has a different meaning for different people. For some, it means monitoring room temperatures from a mobile phone, whereas for other, it is controlling garden lighting from a laptop computer. For sports-minded people, it might mean […]

This instructables show how to test ESP board on bread board without soldering, especially for ESP-07 and ESP-12(E) and may be ESP-03. ESP board most require 2 mm pitch connector but most bread board are 2.54 mm pitch, It need some tricks on connect between ESP board and bread board. Step 1: Preparation 2 mm […]

Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point.  The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy […]

24 Channel USB Connected LED Controller, upto 1A per Channel This device is designed to be a versatile high-current LED controller, with the ability to sink or/and source currents up to 1A per channel with dissipation of up to 2.5w per channel. The various jumpers and transistor placement allow the device to control many different […]

The L3GD20H is a low-power three-axis angular rate sensor. It includes a sensing element and an IC interface able to provide the measured angular rate to the external world through digital interface (I2C/SPI). The sensing element is manufactured using a dedicated micromachining process developed by ST to produce inertial sensors and actuators on silicon wafers. […]

The MAX1720x/MAX1721x are ultra-low power stand-alone fuel gauge ICs that implement the Maxim ModelGauge™ m5 algorithm without requiring host interaction for configuration. This feature makes the MAX1720x/MAX1721x excellent pack-side fuel gauges. The MAX17201/MAX17211 monitor a single cell pack. The MAX17205/MAX17215 monitor and balance a 2S or 3S pack or monitor a multiple-series cell pack. To […]
