Description

Features

  • Pulse Operations with the 16-Bit Micro Experimenter by Thomas Kibalo
    Time to add more tools to your Experimenter board! This month, we’ll look at the digital pulse capture and generation capabilities.

Projects

  • Thermoelectric Powered Sunflowers by John Iovine
    This summer, create a nice evening ambience using a thermoelectric generator that gets its power from the sun.
  • Make the Bike Blinker Plus by David G. Bodnar
    As a cyclist, not only will you be more visible at night with this handy gadget that fits into your helmet, you’ll also know the air temperature!
  • Build the WatchPuppy by Jim Sky
    Keep your unattended computers working in the event of a software crash with this device that can reboot your modem, router, or other networking device when needed. You can also use the WatchPuppy as a remote monitoring device for temperature or voltages. This is an open-ended project that can be expanded to meet your specific needs.

Columns

  • Techknowledgey by Jeff Eckert
    TechKnowledgey 2010
    Artificial black hole created, your own teleprompter, talking with pedal power, plus other stuff you’ll find interesting.
  • PICAXE Primer by Ron Hackett
    Introducing Tex and Rex: The IR Twins
    In this month’s column, we’re going to re-visit the infrared realm, but this time we’re going to take a different approach and develop two very simple IR boards — each of which serves only one specific function. Rex will be our IR receiver and Tex will transmit IR signals to Rex.
  • Q&A by Russell Kincaid
    Reader Questions Answered Here
    Irrigation timer, video switch, plus the MailBag.
  • The Design Cycle by Fred Eady
    Taking USB Downstream
    Up to this point, we’ve been working our USB device magic on an upstream connection to a USB host. The time has come to take on USB host responsibilities and originate a downstream connection from the Type A USB connector of a USB host we will design and assemble.
  • Open Communication by Louis E. Frenzel
    Crystal Clock Oscillators: The Heart of All Communications Products
    If you look inside any electronic product today, there are a few circuits and components that are common to all of them. For example, every product contains at least one microcontroller that runs it. Another circuit that you will see — especially in communications products — is a crystal oscillator or clock. This circuit generates precise timing signals that control everything else — including that microcontroller. In communications gear like radios, that crystal is the source of the exact opera.
  • Smiley’s Workshop by Joe Pardue
    Smileys Workshop: An AVR C Programming Series (Part 25)
    AVR Memory Part 3: Program Memory In A Flash!
  • How a Capacitor Works
    The function of a capacitor is to store an electrical charge. In this circuit, we will watch an LED slowly dim as the capacitor discharges.
