And what are your solutions for GPIO related stuff like temperatur sensor or PIR-Sensor (infrared or radar).
Do you always use the laptop screen or how does this look?

@Mykle1 was so right…LOL

Habe you compared the Laptops Power consumption with the raspberries? ;)

For sure it runs way better, but if you use just normal stuff, it is absolute not necessary imho.

Most of us use the mirror on the wall, without tons of cables (execpt Power) viewable. With a Laptop you have to be more tricky.

But nice to know that it runs easily With Ubuntu :D

I don’t need a GPIO solution for temperature sensors. My thermostat already tells me that information. PIR sensor for motion? Not necessary. A simple usb webcam will do the trick. You can use the laptop display or you can use an external monitor when the laptop board supports that. I haven’t seen one that doesn’t.

You’re not just running a raspberry. You’re also powering a display. I have not compared but I am sure there is a nominal difference. If there is a difference, the performance boost outweighs the cost difference.

Normal stuff? There are single modules that the Pi struggles with. I don’t accept stuttering transitions, RAM inadequacies, system overload and heat issues just to use a Pi.

I don’t know how you speak for “most of us”, but ok. Disassemble the laptop. Fits behind mirror as easily as a Pi. Only the power cord showing. How is this different from a Pi mirror? It’s not.

Raspberry pi is fine to mount a prototype, but with MM and Kalliope shows freezing moments …
On the laptop: everything is easy and the answer is immediate.
My next MM with Kalliope (voice) will be in a mini PC. More expensive, yes, but it compensates the normal fluency that these app requires

@Mykle1 How do you did the wake up with a webcam?
Let’s say a notebook has always an integrated webcam on top of the display. How do you wake the screen up like a PIR-Sensor does?

I use voice commands with Hello-Lucy to put my displays to sleep and to wake them up. I use this on my Pi mirror. https://github.com/alexyak/motiondetector

@Mykle1 Using old laptops makes sense to me too. But i do have one question; how do you manage heat and fan noise? I’m concerned that an old laptop gets hotter than a Pi behind a mirror and if its using a HDD and has a fan it must either get noisy or hot (if you disconnect the fan)

@mdhenriksen

I have not found heat to be an issue at all. In fact, by removing the motherboard from the case, the temps are actually lower, even when placed behind a mirror. As long as the construction of the mirror is well ventilated, I don’t think that would ever be an issue.

I do not remove the fan. I’ve found that in a normal environment, (people, tv, ambient noises, etc…) the fan noise isn’t even noticeable. Only when the house, or room, is completely silent is the fan audible. For me, this is not an issue when a mobo mirror outperforms any Pi mirror, hands down.

Note: There are silent fans these days but I have never used them with a mirror. I’ve never felt the need to but that is certainly an option for anyone.
