Intro My cheap plug in hot glue gun died and looking for a replacement I found this: the Bosch GluePen What does it do? it’s a hot glue gun for 7 mm glue sticks that warms up in 15 seconds. Charges via micro USB. Much better than my old one that needed ~5 minutes to […]

This projects uses 8MByte SDRAM from a 168 pin DIMM SDRAM and generates videosignal for a VGA monitor with a resolution of 512×480 pixels with 256 colors at 60Hz using mega8515. The project uses burst mode of SDRAM, which can feed up to 512 bytes without MCU help. This means that MCU can do anything […]

It provides easy and safe auto-login to your OS, bank accounts, mailboxes, corporate network or social media. Pastilda stores encrypted passwords in its memory. You can request […]

Description This project is a hardware mechanism to provide secure “two man control” over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data is also encrypted with a key that is stored in a key storage […]

7Ah Sealed Lead Acid Battery  7Ah Sealed lead acid battery is a very popular battery which people use in most places like fans, LEDs etc. The reason behind popularity of 7Ah battery is due to its medium size and medium Ah rating. By medium means, its size and ratings lies between the small batteries and […]

In 1982, the UK’s best selling computer, ZX Spectrum, was released by Sinclair as 8-bit personal home computer highlighting the machine’s color display. And today, a group of makers are introducing the Spectrum Next, an updated and enhanced version of ZX Spectrum. The Spectrum Next is fully compatible with the original one. It enhanced to provide a wealth of […]

Introduction This tutorial continues from Character LCD Displays – Part 1. In this part we will connect the LCD module to an Atmega8 microcontroller, then write some code to drive it. The Circuit Our first task is to build the circuit. We will be using an AVR 28 pin Development Board. For the power supply […]

During Embedded World 2017 in Nürnberg I was lucky to get a handful LPC800-DIP boards. To get all students who were lucky to get one, here is a tutorial to make that very exciting ‘blinky’ application on that board: MCUXpresso IDE Series This article is part of a series to get up to speed using […]

It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container […]

Purpose of this article: 1) to learn how to connect the Micro controller in a simple circuit and how to power it 2) to see how to create a simple programmer (a device to connect the micro controller to a PC for uploading software) 3) to present a simple software program in C that controls […]
