IR Blaster (progress)

[hek]

I know that @scalz have a blaster project going as well

[blacey]

@korttoma Apologies to you and others; I wouldn't say that I have abandoned this project but it is fair to say that I haven't had the time to devote to this either so it is woefully stalled. @scalz is working on something similar that may fit but bill nicely after which I will decide whether this warrants further development or not.

@korttoma
guys are true :)
I'll order next week my pcb. i'm taking the weekend to think about my design. perhaps will do a dhl :blush: as i have other things to order and i'm an impatient child..
Of course, i'll share my workn and hope to work with @blacey . this will be a Mysensors project ;)

@blacey @scalz
I'm thinking of starting to do an IR blaster on my own, any chance to get a glimpse of what you are cooking on your side to either wait / see what kind of function you plan?

On my side I'm thinking of:

• Eventually esp8266 based (probably using a WeMos mini Pro) to allow a wide range of usage even out of MySensors.
• Micro usb powered (using the WeMos' port)
• SMD nrf24L01, eventually RFM too if it fits on the PCB.
• optional ATSHA.
• IR leds on the side (roundish PCB?)
• Optional IR receiver

@emc2 That pretty much sums up the above sans ESP8266 vs. Atmel 328p... My next iteration, albeit delayed, uses an SMD footprint compatible with both NRF and RFM. I had originally included an Si7021 temperature and humidity sensor but that isn't really necessary. @sparkman had requested a barrel connector to drive external IR LEDs.

[scalz]

@emc2 "almost" same specs on my side, except i'm gonna use esp32 :)

[emc2]

@scalz Cool! Let me know when you have some details on that. I may stick to esp8266, esp32 seems to be overkill for what I'm thinking, but if you have any tips let me know.

@blacey I saw this request, I can see the use of it, will see if I end up with a spot for one. One thing still, are these standard in term of where is ground and where is VCC on the mono 3.5mm jack? (I assume GND is "outside" and VCC is the "tip" but I may be wrong)

Googling this gives some different results but this one seems most reasonable:

Picture was taken from here.

Maybe one jack can be used for both purposes? In learning mode you could have a sensor in the jack and otherwise you could have a IR Blaster in the same jack? Just a thought.

@emc2 hehe. i don't think this is overkill ;) depends on what features. well let's see how it will work. mine is already designed but i won't have lot of time before beginning of the year now :grin:

Agreed, depends on the features, in my case I did not really think of any additional features, just IR stuff. PCB was designed yesterday, I will play with a protoboard to check if everything works and then will see how to improve everything before ordering.

For info, Luminara works with USB-UIRT with windows (Eventghost)

Code IR ON:
0000 006F 0000 000A 01DD 0054 00F1 0053 002C 007B 002D 007B 002C 007B 007C 002B 002D 007C 002C 007B 007B 002C 007B 0FF1

Code IR OFF:
0000 006F 0000 000A 01DD 0054 00F2 0053 002D 007B 002D 007B 002C 007B 007C 002C 002C 007B 002D 007B 007B 002C 002D 09F6

With Eventghost you can create request HTTP to Trigger IR signal

I learned code IR with LM Remote KeyMap beacause EventGhost don't learn signal
