POWER SOURCES: THE GOOD, THE BAD, AND THE UGLY
With few exceptions, every electronics project needs a power source.

 

What you don't know about your project's power source could be a problem. Learn the most important features you should care about for four common power sources, how to measure them, and what to expect.

 
 

BUILD YOUR OWN PIC TRAINER FROM SURPLUS

Assemble a versatile and high quality PIC trainer from stuff in your junkbox.

 

Assemble this versatile PIC trainer using only surplus parts. Belying its humble origin, this really is an open-ended and high quality learning tool. Thanks to the breadboard-like nature of the trainer, it's a snap to go from a theoretical concept to a working project in a matter of minutes.

AN ELECTRONIC CHESSBOARD USING RGB LED STRIPS AND HALL EFFECT SENSORS PART 2
Create the software needed to accommodate two players.

 

Part 1 of our electronic chessboard build finished the chessboard circuit and its construction, and we also looked at how the software knows when a piece has been moved and what that piece is. Let's wrap things up and create the software needed to accommodate two players.

 
 

MakerPlot — THE DIY SOFTWARE KIT PART 3
Graphical plotting, data acquisition, and control software for your microcontroller.

 

This time, learn how to connect your microcontroller to the software to plot a single channel of analog data. Plus, see how to scale raw ADC data into corresponding voltage levels so you don't have to do math inside your micro.
