Microcontroller and Embedded Systems

Since its founding in 1988, Circuit Cellar has delivered exactly what its paying subscribers demand-intensive, exploratory articles about hardware and software methods for embedded-control systems.

Circuit Cellar – The Magazine for Computer Applications

Circuit Cellar Ink, the best magazine devoted to hardware and embedded computer development, or “What’s Inside the Box”.

Circuit Cellar - The Magazine for Computer Applications

Are you wondering how it all began?
By Steve Ciarcia (Founder, Circuit Cellar)

“His first statement upon hearing about BYTE’s redirection was “How about we start our own magazine?” We had the staff, the expertise, the credibility, the support, and most importantly, the money. It was time to go for it.

Look no CPU! – Built with MyCPU which is made of discrete logic gates as the Bricks. Homebrew Computer for Education and Experimenting. Dennis Kuschel is  the developer of MyCPU.

Homebrew Computer – MyCPU

The MyCPU is a “Central Processing Unit” that is completely built with discrete logic gates. Over the years the project has grown, and now the MyCPU is the brain of a real Personal Computer. The computer has the following capabilities and features

This can also be roasted on a single FPGA Board.

The “MyCPU v2.3” is ideal for education, and is a nice project for enthusiastic hobbyists. The system uses COM1 for terminal communication and COM2 for file service. The personal computer acts as file server. There are several applications you can use on the MyCPU.

Located in London, Earthshine Electronics is a source of parts and kits relate to Arduino. Other electronics or microcontroller needs also.

Digital Barograph made with SCP1000 & GLCD

Arduino Mega Project – Measurement and Data Logging. Digital Pressure Sensor and 128×64 Graphic LCD. Plots graph of current pressure, temperature variation with time.

This certainly is a good project for college students. You can also enhance it for multiple channels, mini thermal printer interface.

Stand alone remote data loggers must be able to take a Standard Thumb Drive for storing and easy retrieval of data. In urban areas a wireless internet transfer is better. In a desert or jungle a satellite data transfer or small flash storage, that can be manually collected and logged into network.

Environmental Monitoring Arduino - The Arduino Guy

The blog of ‘The Arduino Guy’ aka Mike McRoberts

The basic premise of the project is to have sensor nodes monitoring things such as temperature, pressure, humidity, light levels and so on and then send that data wirelessly back to a base station which will upload it to a web server.

Some projects are Audio VU meters, Serial Port PIC programmer and other interesting articles. The low and high logic levels are displayed by LEDs,which are OFF if the probe tip is floating or connectedto a hi-impedance (>220k) output. A pulse transition isdetected and is indicated by turning on the LED for80 ms.

Logic State Analyzer – The analyzer fetches 300 single bit samples at a select-able rate (in 16 steps from 40 Hz to 1 MHz). It has aprogrammable start at High-to-Low or Low-to-Hightransition at input. Digital waveforms are displayed in apseudographic mode on the LCD
