Prepping my first build. Care to check my work?

Hmm I may go that route. I like how well contained everything sits in your rig.
Advantages:
When you shut down your Pi how will you turn it back on? Pull the plug and plug it back in? Hell no! A (mini) power strip with a breaker switch works perfectly. Turn the switch off (after shutting down your Pi) and simply turn it back on. Boom! The Pi now has an on/off switch.
Extra outlet. After you’ve plugged in your Pi and your monitor, what then? My mini power strip has three outlets. That’s all I needed, but as builds become more complicated and require power for other devices (LED’s etc) then a six outlet strip can be affixed to the wall of the mirror box. Mine is on the bottom.
Less cabling. With the power strip you can modify/make extensions of exact length so there’s less clutter behind your mirror. I made a short orange extension (see picture) because the power plug for the Pi “stood up” when plugged in. I couldn’t have that. Now it “lays down”. Yes, you could do that without a power strip but do you really want to splice all that wiring? And how would that look? Hell no! (I like saying that) :-)
This is just my opinion, and others may offer you better solutions, but I think this a very efficient and neat way of doing things, and you get the added benefit of an on/off switch.
P.S. At the time of this build the mini power strip was a $5 add on item at Amazon. You can’t beat that with a stick. :-)
Peace!

@Mykle1 Awesome, thanks for your thorough response!
I’ve hit a snag with the monitor, I don’t know how to get the bezel off. Videos online for this same model (but apparently different sub-model) have screws and clips in places where mine does not. I’ve got the Acer AL2216W sd. Would it be ideal to just use brute force on it? Hell no! There’s gotta be a better way, but I haven’t found it. I ordered a jimmy and may just wait for it to arrive to try and crank that thing open. Any advice would be much appreciated :-)

Ha ha! :-)

I’ve never encountered a bezel that didn’t just snap off so be as careful as you can be. I know someone that cracked a 32 monitor while removing it from the casing. :-(

- Give a thought to power. Are you routing the power through the wall? Through a hole in your internal framework? Consider that at the moment, you have to power the Pi and the monitor, so that’s two cords.
That is a good keyword. If u just want one cord u can think about using a step-down converter.
Don’t know what Voltage your monitor will be using. In my case my monitor needs 12V and the RPi 5V as normal.So i choosed a big 12V power supply (5A or 60W) to power both.
Then i ordered a DC-DC Step Down converter: https://www.amazon.com/DROK-Converter-Step-down-Regulator-Stabilizer/dp/B019RKVMKU/ref=sr_1_5?ie=UTF8&qid=1516968110&sr=8-5&keywords=lm2596&th=1
connect the 12V output of the power supply to the converter input and parallel to your monitor.
adjust the converter output to 5 - 5.1V and connect it with your Pi :)You can see an example here: https://forum.magicmirror.builders/topic/6048/my-first-mirror-until-now/12
This looks like the way to go, though perhaps a bit more advanced than I am. I think I’ll give this a go when I build my second mirror :-)
-
a last hint, which is more software suggest:
https://github.com/gilyes/pi-shutdown
order one push button more (if u tough about before), so this is nice to shutdown and boot up your Pi safely :)

@Mykle1 Could you show me how this mirror looks from the front? Do you have it vertical or horizontal?

@Mykle1 Dang, that’s pretty good lookin’. I especially like your frame. I think in some ways the frame makes or breaks it. With a poor/ugly frame it loses it’s “future tech” feel and instead looks tacky. But what you’ve done with a high quality frame keeps the mirror crisp and communicates that it’s not some poorly thrown together novelty/oddity. I think it’s similar to when you see what was once a very nice car that’s been beaten up and not lookin’ good.
I’m probably not going to try to go bezel free for my first build, but as it happens my next door neighbor is a big wood working guy. I’m gonna ask for his help with that part of this. I just gotta think of some kind of gift I can give him in return…
-
Thanks for your kind words. Really, I made that frame from a $12 piece of molding from the local Home Depot. Hell, you could buy a $6 miter box and do the same thing yourself.
You can see the whole build here

Get him a six-pack of beer. It will take him less than five minutes to miter a frame. Or. get yourself the beer and make the frame yourself. Then you get all the glory. :-)

@Mykle1
Also you may have mentioned this earlier and I’ve forgotten, but what size is your monitor? I’m considering upping my size… =-/ -
@Mykle1 Heh I might do the woodwork on my next one. I plan to make at least a few of these.
He’s a very talented woodworker, he could make it look better than I ever could. Worth a few beers at the very least. I need both the rear frame and bezel cut, so maybe a 24 pack is in order :-)
-
That particular monitor is 22" diagonal. Sure, get him a case. Just don’t let him drink it until he is finished with your frame. ;-)
-
The Jimmy arrives today and unless I can come up with a better idea I’ll just be trying to crack this thing open like a monkey with a rock.
I got it for just $25 and could probably find another use for it, so I’m half tempted to look for another cheapo that may be easier to open. I dunno man. I dunno.
-
Heh! Go easy broze, go easy! :-)
-
@Mykle1 Is there a reason people seem to favor computer monitors for this project than TVs? There are some cheap flatscreens in my area for pretty cheap.
-
I’m sure there are reasons but I don’t know what they are. Perhaps someone else will chime in here, or, you can search the forum. I think I remember some chatter about using TV displays.
-
- Most tv’s show stuff like “signal lost” on screen when you disable hdmi in raspberry to hide the screen, and in some tv’s you cannot disable that
- Cheap tv’s have a poor resolution. The 32" I bought for some bucks only runs 1366x768 and text on your mirror (calendar for example) looks blurry.
But you can still live with it. I will use mine to see if we actually use the magic mirror at all. Then I can still invest money in a better display add replace it
-
Think this is too old/bad to be a good fit for such a project?

@mykle1 @yawns @bhepler @ninjabreadman @cruunnerr
After a bit of a hiatus due to other projects, I’m back at it. Think I should open a new post as the site suggested?
I got two cheap ~20" monitors and cut two panes of glass to size. I figure the first one I do will be kinda an MVP (minimum viable product) approach, and with the second I’ll customize it more to my preferences.
My main question is how to securely attach the wood rear frame to the monitor. This isn’t a glue situation is it? I’ve got few heavy duty glues but that still doesn’t “feel” secure.
The guides I’ve seen seem to gloss over like it’s obvious. To me at least, it’s not.
Remaining little questions:
How thick should/must the wood for the frame be? How much heft does it need to properly support the monitor/mirror? How much space can I safely save by cutting it down to get it closer to flush with the wall?At least in my mind, the back frame shouldn’t encompass the entire perimeter but be strategically located on the back of the monitor. But maybe I’m wrong here, as I suppose it serves the purpose of blocking the view of the inner workings.
Thanks for all your help along the way. I’m looking forward to sharing pics of the completed beta build as soon as I can!
