Desoldering braid makes an invaluable service at development or rework. Everyone who´s ever tried to suck off a solder from a solder pad by means of a solder absorbing braid (wick) will probably confirm, that this tool belongs to a “must have” equipment of every professional or amateur workplace. What´s the charm of a desoldering […]

Description Water Level Alarm is a simple project to detect and alarm once the water level in tank or Aquarium reaches at certain level. Circuit is based on popular NPN transistor BC547 which act as switch, Sensor also made on PCB, when the water reaches the sensor PCB, base of transistor connected to positive supply,
I purchased a battery operated smoke/fire alarm few days ago and it showed up today. It runs on 9V and will make a loud sound if smoke is detected. My intention was to hook it up with my home automation system so that I would receive alert if it would go off including SMS, pushbullet notification

Curious C-Beeper is a fun to build little probe that can be used to quickly detect the capacity of capacitors in pF nF range, test their stability with temperature changes, find broken wires, locate wires, trace wires on PCBs, and to locate live wires behind the walls without touching them. The circuit uses three transistors
What is MicroNFCBoard? MicroNFCBoard is an integrated development platform that makes it easy to use Near Field Communication or NFC (What is NFC? see below for more info). It contains a NFC transceiver, a microcontroller and all the software you need to use NFC. It can be used with an Arduino, Raspberry Pi, mbed or

National Instruments has introduced an embedded System-on-module (SOM) development board with integrated Linux-based real-time operating system (RTOS). Processing power in the 2” x 3” SOM comes from a Xilinx Zync-7020 all programmable SOC running a dual core ARM Cortex-A9 at 667 MHz. A built-in low power Artix-7 FPGA offers 160 single-ended I/Os and Its dedicated processor

Monolithic Power Systems (MPS) MP3364 4-Channel Boost WLED Driver is a step-up converter with four-channel current sources. The device is designed to drive white LED arrays as backlighting for small- or medium-sized LCD panels. The device uses peak current mode as its PWM control architecture to regulate the boost converter. Four-channel current sources are applied to the LED

Researchers at the University of Cambridge have created a new high-temperature superconductor capable of trapping a magnetic field of 17.6 Tesla, improving on a record set over a decade ago. The advance is yet another step toward making superconductors viable for building effective large-scale smart electricity grids, maglev trains and flywheel energy storage. First discovered

I’ve always enjoyed electronic kits of all kind and like many of you will credit them for the foray into DIY audio. Over time as my DIY skills matured I found myself taking the DIY route for projects far more often than relying on kits. While I will always enjoy electronic kits, I generally won’t

I had a bunch of random inductors in some random drawers and I wanted to know what values they were. These values are quite often not obvious by looking at the device. Colour codes for old ones were not standardized and some of the coloured rings on inductors can be faded or discoloured so that
