Driving three IR LEDs is done to boost the transmitting power.

#INFRARED READER FOR PC SERIES#

The transmitter consists of a PN2222A transistor (but any general purpose NPN transistor will work) which drives a series of three Infrared Light Emitting Diodes (IR LEDs). The receiver will output a logical one (0V) when the remote is transmitting a 38 kHz signal, and will output a logical zero (+5V) during periods of silence. Its job is to convert 38 kHz modulated IR signals from your remote control into digital ones and zeroes. The infrared receiver consists of the TSOP4838 IR receiver module. The circuit can be divided into a number of functional groups. On Linux, make sure you're using the libpcap 1.1 (packet capture library) or later.

A USB trace capture program like USBTrace or USBlyzer (for Windows) or Wireshark (free on Linux).

A good logic analyser like Logic (works on Windows or Linux).

Unfortunately the PIC18F25K50 is not supported by Pickit2 and even Pickit3 seems to lack support (well, I couldn't get it to work, so I bought a mikroProg which seems to be better anyway).Īnd in case it doesn't work for you first time, you may find it helpful to have:

A micro-controller programmer able to program a Microchip PIC18F25K50 micro-controller, such as Mikroelektronika's mikroProg for PIC.

A Hakko T18-B 1 mm ball tip (or similar) is fine - even for the ICs.

There are plenty of tutorials on the Internet showing how to handle SMDs. That is not as hard as it seems as the design uses only relatively large SMD parts.

To be able to solder small Surface Mount Devices (SMDs) to the PCB.

You just need to zip them up and email them to the manufacturer, pay your money and wait. All the Gerber files are available on SourceForge. I used a company called ITEAD who have very reasonable rates and manufacture very high quality boards.

A PCB manufacturer to make a double-sided PCB.If you choose to build the Surface Mount Technology (SMT) version, then you'll need: A micro-controller programmer able to program a Microchip PIC18F2550 micro-controller, such as a Pickit2 or you can make your own (search for " pic programmer" on Instructables).I soldered everything on both the THT and SMT boards with a Hakko T18-B 1 mm ball tip. A good soldering iron with a fine tip.I use inkjet transparencies, an ordinary fluorescent desk lamp as a UV source, and Kinsten positive-acting presensitised board, and ferric chloride etchant. If you choose to build the Through Hole Technology (THT) version, then you will be making a Printed Circuit Board (PCB) or at least a matrix board, soldering electronic components onto it, and then programming a PIC micro-controller, so you'll need: This project is for reasonably advanced electronic nuts.but if you stick with it anyone can make it.
