README
README.mdLIRC High-Power Serial Transceiver
This electronics project spawned from my need to blast Philips RC6 infrared codes across my entire living room and remote control my existing Feller Zeptrion [1] (house control) electric installation, with the help of the Linux Infrared Remote Control (LIRC) [2].
Unfortunately, my existing USB dongle would not transmit RC6 codes while my spare serial transmitter would lack the power to blast IR accross the entire room.
I thus designed this High-Power Serial Transceiver with the following key points in mind:
-
high-power IR transmission, using an external power source such as the RS-232 12-volt "Power-over-System" provided by some card (e.g. Exsys 44092-2 [3]) or using a 9-volt battery
-
versatile IR reception, compatible with both 36/38kHz and 56kHz remotes
-
indicator LED to monitor IR reception (and transmission)
-
do-it-yourself using "off-the-shelf" standard components [4]
starting with the designs proposed by LIRC and its contributors:
http://www.lirc.org/transmitters.html
http://www.lirc.org/receivers.html
and using this opportunity to over-design some of the components, such as to protect the high-power LEDs to be driven out of specifications by the full range of potential RS-232 signals/voltages (using a high-pass input filter and a two-transistors constant current source).

Questions
How big is the LIRC HighPowerSerialTransceiver PCB?
It measures 55.9 × 82.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LIRC HighPowerSerialTransceiver use?
40 parts, built around the LM2936Z-5.0, LM2937ET-8.0, TSOP2238 and TSOP2256. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LIRC HighPowerSerialTransceiver KiCad files?
From the cedric-dufour/LIRC-HighPowerSerialTransceiver repository on GitHub, at the commit this page was made from: the board is LIRC-HighPowerSerialTransceiver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LIRC HighPowerSerialTransceiver design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
