Every now and then you run across something that is simple, useful, elegant, and ... well, pretty cool really. Such is the case with the CONVERT utility (for Windows 95, 98, NT), which was created by Josh Madison, and which allows you to quickly and easily convert units of distance, energy, force, light, mass, accelleration, and much, much more ... But don't just take our word for it. Download this little rascal and see for yourself!
Note that the Convert utility is delivered as a ZIP (compressed) file. Right-mouse-click on the link and then use Save As (or Save Target As) to copy it to your system, then unzip it and run it.
Soldering is a skill that only comes with practice, but the tricky part is learning how to start. So EPE Online is delighted to present Alan Winstanley's internationally acclaimed Basic Soldering Guide (including some fantastically detailed photographs), which describes how to chose a soldering iron and how to solder and desolder.
What do those color bands and dots on Capacitors and Resistors mean? How can you tell the values of capacitors and resistors? This FREE booklet (which was provided with the Dec 98 issue of EPE and EPE Online) describes two main groups of components: resistors and capacitors. These components are examined in non-technical terms, and these discussions are intended to enlighten those who are comparative newcomers to electronics. These discussions include resistors, potentiometers, varistors, thermistors, light-dependent resistors, and fixed and variable capacitors.

Anyone who has tried to read the data books from the manufacturers of LCD displays will have discovered that these references are incomprehensible on a good day and unbelievably confusing the rest of the time. So EPE Online is proud to present a two-part article culled from the EPE archives:
In Part 1 we introduce the various types of displays and how to control them.
In Part 2 we discover how to drive the display with an 8-bit or 4-bit microcontroller.

Many people find that working with binary numbers is a little tricky at the beginning, but it's really rather easy once you understand the basic concepts. This bonus article (which is associated with Part 3 of the PhizzyB series appearing in the Jan 99 issue of EPE and EPE Online) introduces signed and unsigned binary numbers, two's complements, the carry, borrow, and overflow flags, and the effect of shifting signed and unsigned values. The article also includes experiments for those lucky rascals with a PhizzyB and/or PhizzyB Simulator.

In this second bonus article (which is associated with Part 4 of the PhizzyB series appearing in the Feb 99 issue of EPE and EPE Online) we investigate the PhizzyB's liquid crystal display (LCD) and discover how to use the PhizzyB in the role of an event timer. Quite apart from anything else, this bonus article also introduces some general-purpose mathematical subroutines supplied with the PhizzyB Simulator. (See also the LCD articles elsewhere in this library). Also, you can Download a ZIP file containing all of the programs discussed throughout the course of this article.
