>I just took a look and it seems that Tx zone splitters still have some logic. Is it true?

 

No the splitters are passive devices , no fancy electronics just resistors for the ir leds.

>What are the characteristics of such blaster (distance over which it works). Someone

 

    Initial testing from memory was 15ft but that was driving the output at around 5mA ,if used in blaster mode say 20mA or more the range would be extended but my testing has been done using the stick on emitter system would need to do some testing . The homebrew unit was txing around 20ft but the ir led was looking at the tv.

Not sure what you mean about patching . But not intending to design another version of the board unless there was a huge demand sorry...

 

>Ideally, I would like to put it in single (or double) UK electric box and attach >receiver/sender to blanking plate. Will that be possible and will it fit?

 

Good question as i said the pcb is approx 75mm x 45mm ????????????

 

 

>And one even more important thing, will it be able to work without HV at some stage, i>.e. will it be possible to connect controller unit to serial port on PC?

 

No ... i did ask when designing the new board if pc comms was required no one replied so i took that as no one interested..........
