DIY: IR and RF multi-way gateway (message translator)
Want to convert consumer IR remote control data to RF xbee data? How about the other direction, going from xbee/rf to IR? How about IR to IR, with different output messages for a given input message? Maybe you need to remap some xbee messages to other xbee messages?
This does all that ;)
Bottom/right is the IR receiver module. Left, in red and blue is the xbee or zigbee rf transmitter/receiver module. Top/center is a pair of IR sender diodes with a 2 transistor constant-current driver circuit. All controlled by an arduino nano module and my own C code.
This is part of my overall 'remote remote control' story; where you can control many things with the kind of user interface device you prefer. Later, there will be a webserver added to the mix so that IP traffic could also play along ;)

Build note: lately, I have been using a lot of these really nice and inexpensive thru-hole double sides (plated thru holes!) perf boards. They are sold many places, amazon included. Its so nice to have mechanical stability from the plated thru holes. For decades, I was stuck using very low grade single sided perf boards. They never held up and were fragile as can be. And because these new boards are strong, I've become a bit bolder in not using chip sockets. It keeps the parts cost and count down, for high speed circuits you get better performance without sockets and usually the parts I'm using are not so expensive, so that if I cannot unsolder them from a board, I'll just call the whole board a 'learning experience' ;) I also do have professional desoldering tools at home, so I am able to remove parts from boards like this if I really have to.
fwiw, the 2 metal can transistors are 2n2222 (the famous 2222) and I believe those are parts I bought when I was a kid, about 40 years ago! Yes, I do have parts in my parts bin from that long ago, when I bought them new ;) Likely from James Electronics; before they changed to Jameco.
