HIR Issue 3: The Infrared Box
The Infrared Box by Asmodian X (Ascii-Schem by Axon)
Hello this is /|smo again <Reader groans,> coming to you live from nowhere important. It just occurred to me that in this day and age, more and more independent computational devices are using infrared transceivers to communicate with the world. Infrared is a cheap, effective, short range communications method. Many people take advantage of this form of communication daily. Only problem is that some times a person, teacher, instructor or any sort of host in general doesn't want people to engage in such activities for one reason or another. So, were going to tell you, the user out there, how to build a fairly effective Infrared jammer. Since it is difficult to name anything within the visual spectrum that hasn't been taken up at least twice, I have chosen "Infrared.966," as the official designation.
My apologies to any one else who designed an IR.966 Box.
The concept and design have nothing to do with me or any design. The Blame..err .. honor of the design goes to an "insane/ingenious" instructor at a certain Unmentionable high school. The concept is simply this: Infrared communications ports just blink out messages to each other, and relies heavily on line of sight. If a person were to create a false garbage signal to the two parties, communications would be unintelligable. The Person did this by placing the IR units at each corner of the room, effectively covering the whole area with unusable Bogus IR signals. The end result of that action caused enough interference to make IR chatting no longer possible.
The Teacher Had essentially hooked up Infrared LED's with 9V batteries. The LED's were on 24/7 of course, which isn't the most efficient method, but it was effective. Axon proposed that we use 555 IC timers to pulse the LED. The end result would be an infrared blinking LED. A person Could tweak the resistance's and get a faster or slower blink rate. Likewise a person could place in a few Potentiometers(POTS) and add some functionality to their new device.

AND NOW FOR AXON'S ASCII-SCHEM
(If you're looking at this in Windows Notepad, Netscape, IE, or any graphical environment, you suck, and furthermore, you need to use a REAL Text viewer. Try using vi, or even dos EDIT. To print this article out from dos or windows 95's cheesy version of a dos prompt, use the following from the C: prompt <or whatever drive and directory you are saving the HiR Text files to> TYPE HIR3-6.TXT > LPT1 If you want to actually see my schems correctly, that's the only way to go for you guys -Axon)
