<![CDATA[Czech mirror in IKEA LILLÅNGEN]]>Hi guys,

after 6 months I finally completed my mirror. I used IKEA LILLÅNGEN mirror.

Components:

Because LCDs high consumption I’d like to switching on/off LCD panel, but the boot up time is almost 8 sec, so the PIR is controling only backlight.

Here some photos. If you have any question, feel free to ask :)

I tested unplugging pin 3 and you are right: the display / backlight ist switched off 👍
I also got me a voltmeter and checked the currents :) seems to be identical to your setup. So next, I’ll connect a PIR, check the current and connect it as you described.

Thanks!

Feel free to help me out guys :)

@TomasZmuda if you look at my option 2. do I need to ground inverter and Pi?

thanks!

It’s simple test. :) Next plug this cable to PIR output and as i wrote in first post, don’t remember hook up ground between LVDS and Raspberry.

http://www.vslcd.com/Specification/T.VST29.03.pdf

“CN2” describes the pinout for the invertor.
Pin 3 is backlight on/off and pin 4 is for the adjustment of the brightness.

unfortunately I don’t have a voltmeter or an oscilloscope at hand. I hope I’ll figure it out somehow :/

your inventor has 6 cables, so one of this should be backlight controller. I can’t help you more, you have to measure it by voltmeter or oscilloscope.

your mirror looks great!

I´m planning to do the same (and I even looked at the same Ikea mirror :) ) and was wondering how you solved tha backlight handling exactly.

You talked about an invertor in one of your posts. My controller has an invertor, too. Can you tell me if your solution would work here aswell?
This is the board with the controller: http://www.ebay.de/itm/TV-HDMI-VGA-AV-USB-AUDIO-control-board-for-15-6-B156HAN01-2-1920x1080-IPS-LCD-/361128251020

Thanks :)

PIR send signal to raspberry, and by some python script open NPN bipolar tranzistor which turns backlight on.

But there was a problem with hight current, and any other problems.

In the invertor the are 4 cables: ground, brightness 3,1-3,5V, backlight 5V, power 12V.

Fortunately the backlight si possible to control via any voltage (not any, but 3V-12V is ok). The PIR has output 5V, so I connected the output from PIR directly to LVDS converter. Be carefull, you have to hook up the groud in raspberry and in LVDS!

Could you share how this is done, please?

But my wife don’t like this, because it isn’t real mirror and you are seeing things like in fog.

Now, I ask some glass companies for price offer and try the real mirror. The price is about 55€. http://glassolutions.cz/cs/produkty/mirastar-chromove-zrcadlo You can translate page via google translator.

One question, where did you ordered the 2 ways mirror?

I’m going for the same thing. Using a PIR to only cut backlightning. Power usage dropped from 38w to 5w. :)
