What are some tips for a complete beginner for a raspberry pi?

Youtube has a grensom
He has a lot of set up videos
I think there will be a lot of help for beginners.

Re: Africa is coming through in MagicMirror project (rep KENYA)

Am interested in this project and also really excited… will be giving you guys weekly update

@bhepler yah I seen those surface table I wanted mine to be more discreet and look more sleek also I will look into the tinted glass but I’m sure I seen glass mirror top tables and coffee tables before but that’s great you pointed that out I’ll look into it more

@bmadeira sku means product

nicely done!

Hello all,

I am trying to create an RFID module on the Magic Mirror and would like to implement a feature that would ask the user for their name, and then assign that name to a tag. I currently have the reading/outputting features running, but can’t figure out how to take a name from the user to be written to a new tag.

Are there any existing modules that either:

Open a popup window that can be typed into Show a input box on the mirror to be outputted Or even open up a terminal window or something like that

Thank you

Ok. Thank you.

thanx,i got it .I test it opening mm ip at chrome and works great only MMM-RTSPSTREAM doent work.It doent show my cam ,maybe has something to do with vlc i am using…Anyway now i have to find a screensaver program for windows that can show a webpage…

For those who want to do it the hard way, I have a tutorial on using cloud VMs to provide a means to connect to your Mirrors. I designed it for multiple mirrors of unlimited number.

I’ll be up front about this: My way is complicated and provides only SSH access to your mirrors. But it is about as secure as you’re going to find. It doesn’t rely on installing unknown services on your Mirror Pi (Dataplicity, RealVNC). It’s all open source and SSH key protected.

@sdetweil awesome!!thank you!!

@justjim1220 it’s spot on

I recently set up mmm-google route which also uses google api. It appears from what I can tell you get a monthly credit of 200 or 300 bucks? So if you go over that you do get charged.

Using mmm-schedualar I was able to set it to update every 15 min in the morning hours then just once an hour hike I’m usually out of the house. That may help with api requests

They’re all pink on the inside.

Same in as they both use the same terrible outmoded methods that is essentially a copy of zram-conf-05.deb.

Since kernel 3.15 zram has been multi-stream and partitioning by core just makes smaller swaps with smaller single page write ability for absolutely no reason.
Also makes no check that any previous zram utils maybe in operation and overwrites.
Ignores the important mem_limit property for sys_admins and completely ignores the hot_plug and remove methods.

I have no idea why that bad script has been copied and emulated so much, but yeah the above are very much the same as zram-conf-05.deb.

I suggest you have a look at https://github.com/StuartIanNaylor/zram-config as it combines many functions that are beneficial for MagicMirror and has a better implementation of zram for quite a few reasons.
Uses /etc/ztab so if you wish you can set up as many zswaps, zdir and a zlog if you wish.
Zlog creates a zram directory which is the upper in a OverlayFS file systems so only on write is a file copied up. It also uses the olddir directive of logrotate so oldlogs are shipped to persistent.
Provides negligible flash wear and an extremely small Zram memory footprint.
Zdir is the same as zlog without the logrotate directives where the MagicMirror directory is loaded via a OverlayFS mount with the upper mounted on zram.
Due to the copyup of COW only files that are write accessed use upper so again the whole MagicMirror dir can be provided with zero SD writes in an extremely small memory footprint.
You can make as many Zdir as you need.
Zswap does actually use the kernel doc methods of hot_plug and hot_remove for zram devices and will work with other zram services.
Also includes the important mem-Limit for sysadmin and Zswap is multi-stream and there is little point making swaps per core but you can make as many as you like.
Linux swapiness and page-cache settings are also based the assumption of HDD like swap and zram is mem not disk so swapiness needs to be increased to 80-100 and page-cache set to 0 for single pages to help cut latency as the default of 3 = caches of 8 pages for disk based caching.
None of the scripts ever seem to provide the tuneables to actually utilise zram performance and again you can set both in the ztab as you set up your swap.

Hopefully the likes of the above will actually read the kernel docs for zram https://www.kernel.org/doc/Documentation/blockdev/zram.txt before they just copy and paste a bad Ubuntu script again.

Not really sure how zram will in anyway give you smooth youtube/video playback though… ? But if its caching locally then yes.
But yeah you can get near memcpy speed with compression rations of up 3:1 or even use deflate or ztstd which are slower and prob not for swap but for text such as logs or much of the data format that nodejs uses the compression can be much higher than the performance base of LZO/4.

Hi @ejay-ibm, was a bit busy last days… couldn’t work on MM. I finally install both MMM-Hotword and Mk2. Works fine but need some fine tuning. Maybe you or anybody can guide/help me on the following:

Mk2 side, i still need to understand how it works and how i can “interact” with the other modules… If you have a simple example to show how to “link” Mk2 with any other modules, it would be very helpful!
As usual thx to all for always supporting the community!

Deze post doe ik in het nederlands omdat ik de nederlandse forum leden wil laten weten dat ik mijn touchscreen te koop aanbied.

Helaas moet ik door verhuizing/ruimte gebrek mijn 42" verkopen en zou graag een ander hier op het fora de eerste keus willen geven tot het overnemen van dit unieke scherm.

alle mogelijke aansluitingen zitten op dit scherm , zie mijn vorige posts.
De laatste tijd heeft het scherm bijna niet gedraaid doordat het uit heeft gestaan.
Bij interesse stuur mij een pb.
