  • Spreadsheet — The Forgotten Analog Design Tool by Thomas Henry
    Nowadays, there’s a ton of software kicking around to greatly simplify the design and construction of electronic circuits. Packages to capture schematics, perform simulations, lay out printed circuit boards, and so forth, abound. The trouble is, most non-professionals can’t justify the typically stiff expense of these, especially when not used on a daily, income-producing basis ...
  • The High Voltage PIC — Part 2 by Robert Lang
    This month, we will build the power supply designed last month on a printed circuit board. We will write the software needed to drive the PIC in a freely downloadable version of the C language. We will discuss the software that drives the A/D conversion, the LCD display, and the pulse width modulation. Then, we will program the microprocessor with the software. I will mention some of the pitfalls in designing a switching power supply and, finally, test the power supply ...
  • Understanding Digital Logic ICs — Part 4 by Ray Marston
    One of the most important events in the history of digital electronics was the development of the new IC technology known as CMOS in 1969. CMOS (Complementary-symmetry MOSFET) digital IC elements have major advantages over TTL types. They are simple and inexpensive, consume near-zero quiescent current, have a very high input impedance, can operate over a wide range of supply voltages, have excellent noise immunity, and are very easy to use ...


  • Back To The Future With Nixies by Andrew Argyle
    Unlike LEDs and LCDs, Nixie tubes are pretty objects made of glass that display glowing numbers or letters — perfect for “count-downs.” Their visual appeal has been embraced by moviemakers who have employed Nixie tubes as count-down devices of bombs about to explode ...
  • Power Line Frequency Monitor by Bob Armstrong
    The frequency of the power coming into your house is 60 Hz, right? (at least it is in the US). Everybody knows that right? On a mailing list that I read regularly, there was recently a long, heated discussion about frequency stability of the AC power that's in our houses ...
  • Microcontroller LCD Interface, A One-Chip Solution by Jay Carter
    LCDs range in size and capability, from the typical wristwatch display, to medical EKG monitors and advanced aviation-cockpit displays. Character (non-graphical) LCDs can be easily incorporated within microcontroller designs, as seen in Figure 1. This article provides a low-cost, one-chip solution for interfacing a microcontroller to an LCD ...
  • Climate Controller by Colin Bernard
    After building a temperature and humidity display — which confirmed my suspicions that my workroom really was making me hot (32° C) and bothered (85% H) — I decided that the answer was to control my environment. Thus, the Climate Controller was born.


  • Open Communication by Louis E. Frenzel
    The Ultimate Wireless Hobbyist
    Wireless has been a hobby for well over 100 years. And looking back, I have actually been a wireless hobbyist for most of my natural life. I have tried almost all aspects of this hobby and have witnessed an amazing evolution along the way ...
  • Personal Robotics by Phil Davis, Brandon Heller
    Building A Balancing Bot On A Budget — Part 1
    You were probably expecting to see Part 2 of the Saga of the Silver Bomber here, instead of this article on a Balancing Bot. To cut a long story short, we left off last month on the Silver Bomber motor controller, with everything designed and just waiting for parts. So, we waited and waited, but only about half the parts came in. Unfortunately, everything appears to be back-ordered, most likely due to the RoHS (Restriction of Hazardous Substance Directive) which is all about ‘lead free’ parts ...
  • Getting Started With PICS by Chuck Hellebuyck
    USB PIC Programmers
    The emails keep pouring in and it’s great. Easy and instant feedback is what makes the Internet so awesome. Though a few people let me know they feel I’m just writing this to sell my stuff, most understand that my goal is to help everyone I can learn how to develop microcontroller-based designs using PICs. I also get several emails from people who have discovered a different Basic compiler and wanted to let me know about its great features. If it gets you programming, then I say go for it ...
  • Q&A by TJ Byers
    Reader Questions Answered Here
    In this column, I answer questions about all aspects of electronics, including computer hardware, software, circuits, electronic theory, troubleshooting, and anything else of interest to the hobbyist.

  • The Design Cycle by Peter Best
    The Dish On DHCP
    Dynamic host configuration protocol, or DHCP, is easily understood by most folks as long as you don't start talking about the code behind it. When you've finished reading DHCP spin of Design Cycle, you'll be able to converse with the best of them about DHCP and how it works under the hood of a microcontroller ...
  • Stamp Applications by Jon Williams
    Goin With The Glow
    I’m pretty sure that Scott Edwards had no idea what he was starting way back in the early ‘90s when he released his first serial LCD. Back then, the target customer was someone like me — a BASIC Stamp 1 user who wanted a nice display but didn’t have a lot of spare I/O pins to support it. Well, as we’ve seen, serial LCD modules have become about as ubiquitous to electronics experimenters as the 555 timer chip. There are, however, environments that can present serious challenges to LCDs ...
