Hi,

I received the monitor controller board way early than expected and got a power supply from Amazon (12V 5A to get enough juice for the board and the RPI as advised):

https://www.amazon.fr/gp/product/B01LT77HW6/ref=ox_sc_act_title_1?smid=A30SNSYXWKC8W6&psc=1

I am very happy to announce that my old laptop’s screen works!

And the board has indeed a 5V output which I tested and seems to work fine!

Next step: get some header pins and cable to power up the RPI from the controller board!

Thank you guys again for your advise.
Have a good weekend

Ok awesome thanks! Lucky for you we don’t see the solder on the picture ;) but I get what you did! Thanks a lot for the advise.

Will keep the post updated when I get the stuff

Thank you guys!

The 5V off the board sounds like a great idea, at least if the model I get has that (the pic on ebay seems to show it).

But if I power the controller board with 12V 3A like recommended and pull 2 cables for a micro USB plug the 5V output (pins 3 and 5 (gnd) let’s say) for the RPI, how do I know how much amp the RPI could (or will) “suck” from there? Because obviously, the screen will drain some power, how can I know what would be left and won’t it be too much or too little?

This is probably basic electronics, I will search on that now but if you have a simple answer for me, I’d take it!

Thank you a lot!

Hey

Thank you so much for your replies! I didn’t think of converters or even that the controller board might do the stuff! I am new to electronics and I guess I am too afraid to blow up stuff, so if I can avoid building things myself, that’s great. Although, where is the fun in that ;)

I am still waiting for my controller to be delivered, here it is: https://www.ebay.fr/itm/NT68676-HDMI-DVI-VGA-LCD-Screen-Controller-Board-Kit-for-15-4-B154EW04-V-B-VB/122620926961?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

And the specs sheet I found: http://www.vslcd.com/Specification/M.NT68676.2A.pdf
Seems like there is a power supply too but it points to nothing on the board. Any thoughts?

I am though concerned about the intensity for the Raspberry. How can I make sure I much amps I need to power it, from 2.5 to let’s say 4 amps. For now I am not planning on plugging anything to it yet, except maybe for a PIR or some other motion sensor and audio later. Cherry on the cake would me a microphone for voice command. But see… do this mean I may need to rethink the power supply as I upgrade my mirror?

Thank you for your help!

Salut @frankoucth !

Super boulot, ça donne envie d’avoir ça dans sa salle de bain !

Je suis à la recherche d’un miroir sur Nantes mais je ne sais pas trop quoi demander aux artisans du coin. Est-ce qu’il faut que je demande un “miroir sans tain” ou est-ce une autre sorte de verre/miroir ?

Je suis tombé sur ce site qui propose du 6mm pour 275€/m2, ça me paraît raisonnable vu l’écran que j’ai (15" pour un petit miroir donc) : https://www.toutverre.com

Merci pour ton aide !

Hi,

I am gathering parts to build my very first MagicMirror and I am looking for a way to power up the mirror with only one plug.

I have a Raspberry Pi 3 that requires (if I am not wrong) 5V 2.1A. And I just ordered that screen controller for my old laptop’s monitor which I am gonna use: https://www.ebay.fr/itm/122620926961. This requires 12V 3A power supply.

Do you know what I can search for to find a power supply that can provide these 2 outputs?
I found this on Amazon but the 12V output handles a max intensity of 2A and I would need 3: https://www.amazon.com/Universal-CUGLB-Switching-Selectable-Electronics/dp/B074FT2LXD

Thank you for your help!
Have a good day ;)
