A battery charger is a device used to energize a rechargeable battery by driving an electric current through it. The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant […]

It fixes a problem you probably didn’t even know you had – unlocking the full potential of your graphics card hardware. By simulating the presence of an attached display, Headless Ghost allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be disabled when there
Linear Technology Corporation has announced the LTC2983 high performance digital temperature measurement IC. The IC is a single chip solution to temperature sensor interfacing; it has 20 input channels for sensor connection and each input can be assigned the characteristics appropriate to the sensor used. This includes 8 standard thermocouple types, 8 RTDs, 8 thermister

This project is an audio amplifier based on TDA2050 and LM1875. This is not an ordinary project, but an attempt to make a PCB that is suitable for TDA2050 and LM1875 and has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient
The Cree LMH2 LED Module provides unparalleled efficacy and light quality in a fully integrated module. Utilizing Cree’s True White Technology, the LMH2 provides beautiful 90 plus CRI lights in 4000 Kelvin, 3500 Kelvin, 3000 Kelvin, and 2700 Kelvin color temperatures. In addition, the LMH2 delivers 97 LPW efficacy across all CCT and lumen options.

RGB LED disco light is a simple project designed around PIC16F72 microcontroller. This firmware is a RGB driver, as name suggests it is used to derive or light red, green and blue LEDs in particular fashion. Its main feature is the pattern shown on LEDs. It is quite difficult to describe pattern in words but

In a bid to encourage greater use of TI’s Programmable Real-time Unit (PRU) built into the Sitara AM335x and AM437x family of devices which power the BeagleBone Black development board Texas have announced the PRU cape. The PRU is made up of dual 200 MHz coprocessors, implementing a low-latency subsystem optimized for deterministic, real-time processing allowing
I’ve start building multicopters (or drones if you like it better) five months ago! My first one was a scratch build tricopter based on a KK2.1.5 flight controller and three DT750 motors. Everything was made out of plywood and pinewood! It held excellent if you consider that I was a newbie pilot (still I am)
