When you directly display MM2 on your raspberrypi you could do an overlay with omxplayer. it supports hardware acceleration which makes it run really smooth with gifs

Especially remember that electron and gifs are really a bad combination especially on the raspeberry pi since it does not use hardware acelleration :unamused_face:

You mean when you start the raspberry PI or that a gif gets played right before the others appear?

Yep thats why I write I don’t know what siye of a cable you use ;)
but since I expected the cable to be very short (step down converter directly in front of the pi and the cable is probably open to all sides
VDE rules say you should use at least 0.5mm² up to 2.5A 2m
and at least 0.1mm² up to 1A 2m

So you should use 0.5mm² to be on the safe side.

0.25mm² should probably work aswell when you do not have long cables and do not stress the pi fully out to 2A ;)
But yes @MadScientist is right you should definetly not get below this

and keep in mind those values are for copper cables. If you use aluminium cables you obviously need thicker cables

hm strange I mean I don’t know the cable size you use, but 5V 2A is pretty much nothing for any cable. Should not really get hot for sure

@The-Bean When it gets really hot I would try with a heatsink
and what happens when you connect it and then turn up the voltage until you reach 5V?

@The-Bean you might want to try with a additional cooler on the converter since the pi is not constantly pulling 2A, so it might work

@The-Bean Whats the buck down converter? I guess the pi is just a to big load for it

Never expect those china buck down converters to achieve more than 50% of what they say they will do (especially without additional cooler)

Well if they have success with it I guess thats fine, but I really doubt it.
I mean in general they use a OpenSource Software, so what they offer is a building service for mirrors and maybe the development of Modules for the company.
Well it is a school start up students can do to try it out. Sometimes failing helps a lot with learning aswell.
btw they are not the only people that take the MM2 build the mirror with maybe (not sure) own modules and sell it
https://www.magirror.one/technik/, so I guess there is either really a market for it or there are quite some failed startups

@Mykle1 Yes will create a omxplayer module for my mirror (although I am not sure wether I have the time this month)

@Mykle1 well your desktop has a gpu but a not a better cpu and ram is not used ;)
And yes expected a slightly better performance given the 17% more cpu speed. However I will just stop playing video files in electron which kills my cpu (83%).
So I tried I different way to show the video. I used magic mirror like I would normalways but the video I did not show in electron, but opened omxplayer to blend the video in.
I tested using top. It shows cpu usage for all cores so don’t wonder about numbers over 100%

With the video on electron using a magic mirror module my cpu usage was at stable 250-260%. Using the omxplayer to show the video and showing the rest like I did the first time the CPU usage was different each time. It was always either in the 20% area or in the 150%. So it is a enormous improvement to the first option and makes it definetly possible to play it on a raspberry pi 3b ;)

Well today I got a pi b+ into my hands and tested it right away. Well sadly there is no improvement at all. The video still runs smooth which I expected, however there is still 83% cpu load while playing it. Will give it a cooler and do not show it a lot of the time anyways so I guess I should be fine anyways

@sharmstr yes I thought that aswell especially because everyone uses the Frame

@sharmstr I see everyone using IR Frames. What makes them better than putting a touchfoil on the mirror? does that screw anything?

@sharmstr No checked that then will contact them ;) in my build the frame would be bigger than the hole in the mid of my frame. So this gap does not fill with dust I would like to fill it but obviously should not filter the infrared ^^ Thought about pmma casting resin because that would fill it nicely and filters until around 400nm and then again above 2800nm. So I guess it should work :face_with_tears_of_joy:

@sharmstr do you know the wavelength of your IR Frame? ^^
Yes Germany makes it over 100$ I like them because they are pretty much the only you could use with touch foils under the glass

@sharmstr they have nice mirrors (wanted to buy one until I saw the shipping costs lol)

@mykle1 ah no I mean in general. I wanted to drop windows already for months ;) But since I need the CAD software I can’t lol maybe I will go over to linux and put windows into a VM just for CAD Software

@Mykle1 just took a cooler from a old PCB I had laying around and some thermal compound. saved me 25 degree
