PCB future is lightweight, low-cost, and flexible: Product how-to

In the last ten years, the technology for manufacturing lightweight, flexible PCBs has made huge progress. Lightweight flex circuits are usually associated with materials like Kapton. The use of those materials is typically limited to high-value applications due to price. Fast forward to 2015, and the landscape has changed dramatically. Printed electronics makes the news on a regular basis. We hear about br ...

DIY Soldering Robot Project Completed

The DIY soldering robot which we have been building in our spare time over the past few months is now working and we have been able to solder some test Raspberry Pi expansion board headers with the machine. Before starting on this robot we looked at the various commercial soldering systems that are available.  Wave soldering machines would have been impractical as the connector is on the top side of the boa ...

64×16 RED LED Marquee

The purpose of this small scale LED marquee is to display messages to our classroom in a more modern and centralized way. In the classroom, this construction would save white board space and is convenient because it can store a large amount of information. It is also fairly simple to program and has a mount, making it easy to place anywhere within the classroom setting. The first step of this project is to ...

Arduino measures heart beat rate from fingertip

The PIC16F628A based heart rate meter is one of the most popular projects published on Embedded Lab. In this article, I am going to show how to replicate the same project using a simpler platform like Arduino. The Arduino heart rate meter will use Arduino Uno, Easy Pulse Plugin, and 4-digit SPI seven segment LED display module. It computes the heart beat rate by processing the analog pulse signal output fro ...

Multi-pole industrial relays provide more possibilities

As we know, a relay is a very versatile component, able to realize also various “sequential” circuits, when for example by switching one relay we´ll switch on a target device and at the same time we´ll enable (or disable) switching of another relay. In these case, it´s an often demand for a relay to have a sufficient number of poles. Majority of such “logic” circuits can be realized even with a common 1-2 p ...

RoomMote- Control the color and sockets of your Room using a Remote, MSP430 and Energia

Buzz..Buzzzz..buzzzzzzzz .. That is how a lone mosquito irritates you in the middle of the night trying to convince you that his lullaby is helpful. Insignificant or not, But truly that is the underlying inspiration for this project. The Mosquito repellents have this obnoxious smell that I would not like to sleep in and these loner mosquitoes who just piss me off by buzzing in the ear, you have to choose a ...

Playing with analog-to-digital converter on Arduino Due

Today I’m going to present some of more advanced capabilities of ADC built in ATSAM3X8E – the heart of Arduino Due. I like the Arduino platform. It makes using complex microcontrollers much simpler and faster. Lets take for example the analog-to-digital converter. To configure it even on Atmega328 (Arduino Uno/Duemilanove) you must understand and set correct values in 4 registers. And it can be much more in ...

With MCP73831 you´ll charge lithium cells easily and safely

Li-Ion a Li-Polymer cells are becoming a No.1 choice for many applications, where they persuade by high energy density, low weight, low self-discharge and for majority of applications also by their favorable flat shape (Li-Po). Their price is also affordable (in regard to their properties) and so there´s usually only one “difficulty” - to solve charging, or more exactly - overall management of these cells. ...
