Re: [LIRC] irsend runs into timeout sporadically

Thanks for posting this - spent many hours trying to suppress multiple repeats and other random behaviour using Stretch. Rebuilt the platform on Jessie and all now works a treat.

Be great to get a working Stretch solution and not bury LIRC in the long term!

Re: Alternative microphone

Thanks for the suggestion k-pi. I did try to plug a USB mic in but it didn't work - that's the limit of my skills! Could anyone explain how this can be done in a bit more detail, please?

Alternative microphone

The microphone board that came with my kit is malfunctioning - it just generates very loud random sounds.

Does anyone have the expertise to explain how I could hook up and alternative mic - perhaps a USB one?

Thanks!

Re: "Local" voice is very crackly

Looks like I have a faulty mic board. Don't get any loud crackling sounds when board removed. Is there any way to get a replacement?

Re: "Local" voice is very crackly

When I run the audio test the speaker works as expected and I hear the voice clearly say " Front, centre. " All good so far. However, when I next try for the mic audio test and say " Testing, 1, 2 , 3 " I get a very loud crackling sound in return not my voice. Anyone else get this or found a solutio...

PHP for Ciseco Sensors over XRF

Call me old fashioned, but I am not a great fan of Python. No flames please!

Has anyone being able to code using PHP to retrieve data from Ciseco Temperature Sensors over XRFs?

Would really enjoy seeing some PHP or Perl solutions to discuss and emulate.

Thanks for looking.

@paddyg - yes, good observation. I have used WiringPi-PHP on other GPIO projects. What I am struggling with is whether if and how this could be applied to control the LCD Module. The required coding is beyond my skill level.

Re: Photocell senosr written in PHP

Thank-you very much! Yes that did the trick.

For anyone reusing this code, just one small change is needed:

Code: Select all

while (file_get_contents('/sys/class/gpio/gpio22/value') ==0)
without the quotes around the zero, instead of
while (file_get_contents('/sys/class/gpio/gpio22/value') =='0')

Re: Photocell senosr written in PHP

The php code above outputs 0s as stated - but getting my brain in gear - if I cover the sensor to make it completely dark, the stream changes to 1s. So the code works, but does not show the range / gradient that the Adafruit Python code generates, for example: 492 497 497 494 523 571 632 840 1453 14...

Has anyone tested Bitbanger with Bye-bye Standby plugs? I already have these devices and would like to avoid buying into a different system.

Also, what recommendations would folks make for Bitbanger compatible remote plugs in the UK?

Hi Angelus88

Can you explain why you connected the relay to the 3.5v pin not the 5v one? The relay spec says 5v.
