Features

Breaking the Arduino Speed Limit — Part 2

Continuing on from our previous article, we'll find a solution to the clock glitches, add a serial LCD screen to free more pins, and introduce an eight-bit fast ADC. Then, put it all together to make an even nicer digital storage oscilloscope.


Setting Up a Test Bench

What equipment do you really need for monitoring and testing all your projects?


Understanding Harmonics Using Simulation

Harmonics form a base line for testing, comparing, and explaining various circuits. This short tutorial shows how you can systematically look at the structure of complex circuits using a simulation program and building block approach.


Meet the ESP8266

It’s not often that a new piece of hardware immediately captures the attention of the builder community. The ESP8266 is the newest example at only about the size of a nickel, with a powerful 32-bit microcontroller and Wi-Fi interface.


Silent Sensors

Ferroelectric capacitors can help take the mystery out of event detection, and save the results to report on them later.


Vintage Computing — I Still Adore My 64

Next in our Vintage Computing series is how to emulate a Commodore 64 home computer on your modern PC.

The Design Cycle
by Fred Eady
From Data Logger to On-Demand Data Storage Device
Roland Riegel, Bill Greiman, and the folks at SparkFun laid the ground work for the OpenLog. OpenLog was originally designed as an “out of the box” data logger. We’re going to add some PIC32MX electron spice to the OpenLog design and turn it into an “out of the box” general-purpose microSD-based storage device.
