Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life.It seems that was […]

Altera has returned to its roots with its latest Stratix 10 FPGA family. The performance figures of this device are certainly impressive. It reminds me of the days when FPGAs were only ranked by their gate count process technology and clock speed. This was before suppliers felt they had to re-style FPGAs as configurable processors. […]

The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm […]

Tiny stereo audio amplifier board has been designed around SMD TDA7266D IC from ST. The TDA7266D is a dual bridge amplifier specially designed for Portable Audio, LCD TV/Monitor, PC Motherboard, and TV applications. This circuit provides high quality audio output of 3W approx. on each channel with standard audio signal input. The circuit works with […]

This module is so simple, I’m surprised it has not been thought of before. You can fit a PIC16F84A or PIC16F628 and it becomes a “buffered PIC chip.” Look at the circuit diagram first to see what the module is doing. It’s buffering 5 of the input lines with a 1k resistor and buffering 8 […]

Samsung’s decision to use more ARM processor cores in its smartphones and tablets is not surprising. But these are not Cortex-A series processors they are Mali graphics processing units (GPUs). ARM rival Imagination has the GPU of choice for the mobile market. Apple, Samsung, Motorola, Nokia all use PowerVR graphic processors developed by Imagination. As […]

Introduction This project will describe how to make a simple digital voltmeter (DVM) using a PIC16F688 microcontroller. The range of this DVM is 0-20V, but you can easily increase or decrease the range of input voltage as your requirements after you understand the voltage scaling method described in this project. The PIC micro reads the […]

Quad Flatpack No leads (QFN) packages offer at least one advantage over Ball Grid Array (BGA) packages: because the electrical connections are partly made via solder lands on the side of the component visual inspection of solder joints and repairing them is easier. Thermally enhancing a package for power applications can be done with a […]

Imec and Fujifilm have demonstrated full-colour OLEDs by using their jointly-developed photoresist technology for organic semiconductors, a technology that enables submicron patterning. This paves the way to producing high-resolution and large organic electroluminescent (EL) displays and establishing cost-competitive manufacturing methods. Organic EL displays can be made thin and flexible with excellent response time and contrast ratio.Products require organic […]

Introduction A digital thermometer is a good choice of project for beginners who just stepped in to the world of microcontrollers because it provides an opportunity to learn using sensors to measure the real world signals that are analog in nature. This article describes a similar project based on a PIC16F688 microcontroller and an LM35 […]
