Ready to cut the apron strings and discover what it’s like to work directly with a microcontroller? This series will help you down that road less travelled.
Want to hear about a way to add sound to your project? Then, check out this review on a selection of low to mid power amplifier modules from Parts Express.
So, what’s the big deal about a vintage computer expo in this modern world of Windows, Androids, and iPads? Not only does this event highlight the TRS-80 Color Computer, but it also showcases a unique fusion of old and new technology.
Frequency counters have been around for years as a standard piece of test equipment in both commercial and hobby labs. If you need one for your workshop, take a gander at the one presented here.
This project spotlights how sometimes the good old fashioned way is the most efficient when constructing circuits.

USB-to-Serial Adapters Revisited
Explore a hardware solution that allows you to use a wide variety of relatively inexpensive USB-to-serial adapter cables in PICAXE breadboard projects.
The Ham’s Wireless Workbench
by H. Ward Silver
Every signal begins with an oscillator — which is a key element in ham radio to generate, mix, and extract the info from these signals. Let's see how to make an audio oscillator, plus learn about common RF types.

A Blueprint for Embedded Wi-Fi
Last month, we discovered that the Numbat Wi-Fi module on the Moray development board can take care of itself in the wild. However, you can’t Wi-Fi in the woods if you have to be attached to the USB port of a laptop. This month, we will replace the USB cable, laptop, and terminal emulator with a simple PIC microcontroller and some tricky CCS C code.
