Looks very nice so far. Keep us updated with your project.
One question: Have you thought about venting? I don’t see any venting holes or anything that allows the heat to dissipate. -
looks very nice let us updated about progress :)
-
@madscientist initially for the test runs I will install two temperature sensors one in the top and one in the bottom to monitor the temperature. I have considered venting holes in the wooden backplate (bottom and top) or above the monitor in the aluminum frame and the same on the bottom but I would like to avoid that as I don’t know how much light would enter the casing.
-
@maros thank you, I really don’t know id it will all work out, I started this for fun as I was reading about the amazing magicmirror2 project and their community. Two days later I am taking apart a brand new monitor… and now I have been constantly working on it on my days off.
-
@madscientist So, experiment done. This is the result of 24h continues running. You can see the temperature has not quiet stabilized but the trend is well below anything critical. My guess would be that with a glass cover instead of the wooden frame I used to insulate the power dissipation should be even better.
-
@yep_dd Less than I thought. But also check the temperature of the Pi. In my case the Pi runs at 63°C at 27°C room temperature. With active cooling it’s at ~52°C.
-
@madscientist good idea, I will do that as soon as I have the actual glass. I have a passive heatsink installed already and in landscape mode the pi usage is less than 25-30% at the moment
-
@yep_dd Same here for passive heat sink and usage. I just placed an old 40mm/12V fan in front of the Pi which runs at 5V. It’s hard to hear in an absolute silent environment. I’ve noticed crashes during the hot period in summer, that’s why I use a fan now and it generall runs smoother. I think at some points the Pi got hot enough to throttle.
-
@madscientist that is true… good idea, I have one 5V 40mm fan as spare. Just one question, are you using your MM in portrait or landscape mode?
