Features

  • Understanding Digital Logic ICs — Part 3 by Ray Marston
    Ray Marston takes a further look at the "74-series" of digital ICs and at basic TTL usage rules in this installment of a four-part mini-series.
  • Elf Turns 30 — Part 2 by Robert Armstrong
    Welcome back! Last month, we printed the schematics for the Elf 2000 and discussed the operation of every part of the circuit. This month, we’ll print the parts list, talk about the construction and testing of your Elf 2000, say a few words about the available software, and then finish up with ideas for expansion ...
  • The High Voltage PIC — Part 1 by Robert Lang
    Can you generate 200 volts DC from a five-volt DC PIC power supply? Yes, you can, and I will tell you how. In this two-part series, we will build a 200-volt DC boost power supply driven by an 18F2455 Microchip PIC microprocessor. The completed power supply (shown in Figure 1) will generate between five and 200 volts DC from a five-volt, DC input ...

Projects

  • Nine Volt Function Generator by Frank Reiser
    This circuit produces a sine wave, square wave, and triangle wave of nine volts amplitude. There are three sections to the circuit: power supply, sine wave generator, and the square wave and triangle wave generator.
  • Interface Your PC to an LED Sign — Part 3 by Michael Simpson
    I was doing a robotics show and needed a way to both attract contestants and display contest results. I had seen a couple LED signs and decided one would be perfect for this kind of application. My only requirement was that the cost had to be reasonable and the sign needed to be easy to transport and hook up ...
  • A Wide Range Period Counter/Totalizer by Robert Reed
    Add another “mighty weapon” to your arsenal of bench test equipment. There are many situations where this build-it-yourself period counter has advantages over your frequency counter.

Columns

  • Stamp Applications by Jon Williams
    SX/B Turns Sweet 16
    There are those — the pessimists among us — that will insist that you can’t get anything worthwhile for nothing; everything has a price. Not so with SX/B. While it may not compete with big, “professional” compilers, in the right hands (i.e., yours) and with a few tricks, SX/B is quite capable and costs absolutely zero dollars. And with the cost of the SX-Key programming tool and SX Proto Boards so low these days, it’s really hard to ignore the SX micro as a viable solution ...
  • 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.
  • Personal Robotics by Phil Davis
    The Saga Of The Silver Bomber — Part 1
    One day Jerry came across some broken Silver Bomber scooters at an industrial surplus house he frequents in town. Talking to the owner, he discovered they had multiple palettes of the stuff lying around. Originally, the owner wanted $35 a scooter — not too bad considering they sold new for $199 plus ...
  • Near Space by L. Paul Verhage
    Near Space Booms And Sounds
    This month, we'll look at two near space experiments. The first one is an engineering test and the second a traditional space experiment.
  • Techknowledgey by Jeff Eckert
    Techknowledgey 2006
    Events, Advances, and News.
  • The Design Cycle by Peter Best
    The Land Of TCP/IP
    In this edition of Design Cycle, we’re going to march cross-country into the land of TCP/IP. Although the same hardware used to transmit and receive UDP datagrams can be used to transport TCP/IP packets, TCP/IP is a bit more complex to code than UDP. However, that’s not going to stop us from getting a microcontroller version of TCP/IP up on a LAN ...
  • Getting Started With PICS by Chuck Hellebuyck
    Real Time Clock
    One of the more interesting things I've discovered about the readers of Nuts & Volts is their diversity. Through the emails I've received from writing this column, I've discovered that both hobbyists and professionals read these articles.
