Ultra high power and long range ultimate IR blaster with ESP8266 controller and Osram Oslon(R) 150° IR emitter


Features:

  • Ultra long range at any angle when used as a universal remote. It works even behind the closets
  • Osram Oslon(R) Black SFH4726S 3.4 W 940 nm IR emitter with radiation angle of 150°
  • ESP8266 controller (ESP-03 module with 1 MB flash). Compatibility with Tasmota
  • LDO regulator with fast transient response permits stable operation and IR radiant intensity regulation
  • Expansion slot with two additional GPIOs that can be used with daughter micro cards for an IR receiver and/or any other I/O function supported by ESP8266's firmware
  • Integrated 8.3 W power supply (Meanwell IRM-10-3.3)
  • Very small: it is simply a power plug box with a transparent cap for IR emission

On GitHub you can find further details on how to connect IRShine to Alexa or Google Home and use it also as a tv remote translator.

    Step 1

    The pinout of expansion slot P1 is:

    • 1: GND
    • 2: GND
    • 3: ESP8266 GPIO0 - connect to GND (pin 2) to flash the firmware
    • 4: ESP8266 GPIO13
    • 5: ESP8266 GPIO12
    • 6: +3.3V
    • 7: ESP8266 RXD
    • 8: ESP8266 TXD

    To flash a firmware of your choice you need an FTDI programmer. It is necessary to disconnect the IRShine from the power outlet, open the solder joint R9 because during the firmware flash the ESP8266 is powered by the FTDI programmer, short the GPIO0 input (slot P1, pin 3) to GND, connect the FTDI programmer to the expansion slot P1 (GND, +3.3V, TXD and RXD) and flash the firmware. When the firmware is flashed you can remove the FTDI programmer, close the solder joint R9 and plug the IRShine into the power outlet.
    To extend the wifi range of the esp-03 controller you can replace the integrated ceramic antenna with a 3 cm wire as seen in the photos.
    To mount the PCB, three self tapping screws M2x7 and three M2x16 are necessary to connect the top cover to the plug box.

    The IRShine uses ESP8266 GPIO14 to control the power led emitter

    Configuration of Tasmota firmware for IRShine

    It is recommended to use latest version of Tasmota (release 8).
    The configuration template for IRShine is:

    {"NAME":"HPIRBlaster","GPIO":[0,0,0,0,0,0,0,0,51,4,8,0,0],"FLAG":0,"BASE":18}
    

    With Tasmota firmware it is possible to send and receive MQTT infrared commands. In this example the MQTT topic is "hpir01" and the command will control any Samsung TV:
    - topic: cmnd/hpir01/IRSEND
    - payload for TV switch on: {"Protocol":"SAMSUNG","Bits":32,"Data":0xE0E0F00F}
    - payload for TV switch off: {"Protocol":"SAMSUNG","Bits":32,"Data":0xE0E019E6}
    With this configuration Tasmota also receives and decodes the infrared commands sent by external remote controls and transmits them with the MQTT protocol. In this example, IRShine receives an external IR NEC command and sends the corresponding MQTT message:
    - topic: tele/hpir01/RESULT
    - payload: {"IrReceived":{"Protocol":"NEC","Bits":32,"Data":"0x40BD906F"}}

  Are you sure? yes | no

I have added the complete project of a daughter card that further expands the capabilities of IRShine by adding a universal IR receiver and an optional temperature sensor

  Are you sure? yes | no

I'm curious, what kind of distance are we talking with this one? Do you have an application in mind for the long distance IR or is kind of a mega-TV-b-Gone situation? (like Times Square b Gone )

  Are you sure? yes | no
