Anyone know how to make a simple infrared reciever and transmitter?

[curious]

i was thinking about using ir to control a tiny plane indoors. im wondering if anyone knows how to make a simple one? i saw the one on reynolds.com (i think reynolds is spelled wrong) but it was complicated using a microcontroller. if any knows how to make a simple ir controller (even just 1 channel!!!!!) that would be great.

This thread is a massive wealth of DIY Infrared recievers and transmitters: http://www.rcgroups.com/forums/showthread.php?t=24711

The main man who contributed the most to this threa is Koichi Tanaka, a japanese member of RC groups wh has a massive japanese website devoted to DIY infrared: http://www.cityfujisawa.ne.jp/~toko/pic/

some used Babelfish to translate the site ( http://world.altavista.com/ ). I personally used SYSTRAN ( http://www.systranbox.com/systran/box ) because i found that babelfish didn't work.

Koichi Tanaka primarily uses the PIC12C509A programable chip for his gadgets so a chip programmer is required.

I have these pages bookmarked because i plan to get right into them as soon as I learn how to use programmable chips.

thanks for your help
i would have never found it. thanks :p

Do a Google search for "40Khz IR" and you will probably find a wealth of info, particularly from robot related sites. I have seen many circuits devoted to makin g an IR receiver to use with a TV remote control. To decode the signal though probably needs a microcontroller. But there will still likely be many examples of how to do it without a micro.

i searched for "40 Khz IR" on google and found transmitters and recievers. i dont know which goes with which. what circuit goes with another for the transmitter and reciever to work. thanks ;p

It depends what you're trying to control. Most simple IR circuits do not have any proportional control of anything they just control multiple ON/OFF circuits because they are developed from things like TV remotes where all the intelligence is in the device being controlled. Even volume controls just send INCREASE or DECREASE signals they don't directly control the output.

If you want to control a single servo it's fairly easy to send a single channel "PPM" signal over IR without needing a microcontroller. But as soon as you go to multiple channels using the trainer output from Tx and a microcontroller in the Rx is the easiest way to do it. You can still use the same IC decoders (4015/4017) used in older radio receivers if you prefer but you will still need some way to create the "Tx" signal.

all i want is to be able to control one on/off funtion. this will allow me to be able to control left and right turns with, for example, on to control a motor or magnet to pull the rudder to the right, off to use a small spring or rubberband to pull it back to the left. this would be extreamely simple compared to what one can do now. thanks

There is a toy car for sale at radio shack that has one control Forwards/backwards. It uses an I/R signal to control it. It costs 10 bucks they are on sale for 5 bucks right now. I have hacked one open today. The reciever works just fine on one LiPo cell, the Range is at least 40 feet in my house. The receiver weighs just over a gram. The leads to the motor work just fine on a magnetic actuator. It will be flying a plane tommorow night.

thats a really good idea!! i cant believe i didnt think of that! i knew that they had those on sale at my local radio shack but didnt think about them for use in infrared planes. thanks for your ideas
