Basic USB Communication (RS-232 Emulation Method)
With the continuous decrease in the use of COM Port devices and COM Ports itselt, the need to migrate to the USB has become increasingly important. = ( . Just take a look at the laptop PCs nowadays, it is a miracle if you can even find just 1 COM Port on it. >< But the good news is... we have got a simple (very simple in fact) way of migrating from the old RS232 to USB, that is...

Electrostatic Negative Air Ioniser With Rotating Ion Thrust Emitters
This EHT power source is very safe when constructed and boxed, as the output is current limited by the high output resistance. However you can get a nasty shock from the individual capacitors if you accidentally touch them while connected to the mains and for some time afterwards.

Resistance Temperature
Detectors (RTDs)
What are RTDs?
Resistance Temperature Detectors or RTDs for short, are wire wound and thin film devices that measure temperature because of the physical principle of the positive temperature coefficient of electrical resistance of metals. The hotter they become, the larger or higher the value of their electrical resistance.

Classic PIC Programmer
Description:
This is my own version of the classic PIC 16C84/16F84 programmer. The design is originally by David Tait. I've made a few changes, redrawn the schematic and done a board layout. All the files you will need are linked below, including software you'll need to operate it. The software is not by me, I'm just including it for your convenience, and you should follow any usage requests the authors have made.

EE498 Project
In deciding upon a project we thought about each of our strengths. Aaron and Kyle are analog designers, Karry and Eric are computer experts. Somewhere out of this we came up with the idea to build a barcode reader. Barcodes are used extensively, and barcode readers present some interesting cross-disciplinary design issues.

Bowden's Hobby Circuits
A small collection of electronic circuits for the hobbyist or student. Site includes over 100 circuit diagrams, links to related sites, commercial kits and projects, newsgroups and educational areas. Most of the circuits can be built with common components available from Radio Shack or salvaged from scrap electronic equipment. Most all of the circuits have been built and tested and believed to perform as described, however possible mistakes may be found.

The USB to RS232 Dongle
With serial and parallel ports being phased out on new computers, hardware designers and hobbyists have no choice but to convert the USB port back to RS232 serial. FTDI have a very nice chip that does just that, the FT232AM. This chip converts USB to a standard high-speed serial port. The bonus with FTDI is the drivers are already written for you. All you have to do is design the hardware and download the serial USB drivers from FTDI's web site.

What is a PICmicro?
PICmicro is the brand name for a family of microcontrollers manufactured by Microchip. The PIC acronym stood for Peripheral Interface Controller, but recently Microchip has renamed their chips to PICmicro. Within this family the flash-microcontrollers (16x84, 16f62x, 16f87x) are ideal devices for hobbyists and low-volume professionals because:
These chips are relatively cheap and easy to get.
These chips can be programmed and re-programmed electrically with simple circuits, and without the need for an UV-eraser (they contain EEPROM or Flash-ROM);
Data sheets, application notes and (assmbler) development software is freely available from Microchip;
There are lots of web pages devoted to these controllers, including (free) designs for simple programming hardware.

555 timer IC
The 555 timer IC was first introduced around 1971 by the Signetics Corporation as the SE555/NE555 and was called "The IC Time Machine" and was also the very first and only commercial timer ic available.

Interfacing the AT keyboard.
Why would you want to interface the Keyboard? The IBM keyboard can be a cheap alternative to a keyboard on a Microprocessor development system. Or maybe you want a remote terminal, just couple it with a LCD Module.
