Alles wat mat Linux ze dinn huet

RasPad Test

So before getting started, i need to clarify something. I’m not getting paid for anything! This is a personal review and was in no way influenced by anybody! This said, here comes my review.

So i fell onto that Kickstarter campaign just before it ended and quickly decided to give it a try. Getting a touchscreen for the raspberry pi platform had always been my wish. I also included a nice screen, casing, and a battery for off grid usage. Honestly the only similar product i know is the pi-top device which comes at another price. Even it’s crowdfunding price was way more expansive… So this was why i decided to give it a try!

Only 4 month later, and this honestly is for Backer’s a really short and fast time, i received my device. Packaging and quality seems to be more than okay! Only a small hunch was the back cover where you place the raspberry. I don’t know if it was meant to be like that but still it closes completely and does what it’s meant to do.

Because i ordered a new Raspbery Pi B+ for my new toy, and because i ordered it to late, i first tried out to connect it to a Windows10 Computer. So as described in some pages on the net, i connected a HDMI from the PC to the Raspad and as well i connected it via Micro-USB to the PC as well, like any regular USB Device. And right out of the box without any more drivers needed Windows accepted the Touchscreen. So very positive for the first impression.

After receiving my Raspi, I continued my tests and out of the box with a new SD-Card with Rasbian on it, it simply worked! No need for touchscreen drivers, no calibration, everything worked fine! You might want to add a keyboard and mouse, because not everything is simply possible without these. But still… You find small and fancy things like that for reasonable prices.

I continued with a few security distributions and I have to say that they all worked fine for the touchscreen! No issues at all. But I realized that you might need to tweak the system for sound reasons. After reading around on the net, I saw a few posts about temperature issues. Some people even modified their houses and added fans to get rid of the heat. For the moment I can not yet confirm that, but I will definitely keep that in mind for the longer tests.

Another thing I will have to test out and keep an eye on, is the battery. I´m not sure yet if it simply is the way the battery indicator works, but I´m pretty sure this is the case. I will use my device for a long term test but here again you can read in some posts that the run time might be shorter than thought. What I can say is that by adding an additional USB WLAN Adapter the indicators dropped immediately to the last indicator, which might confirm my initial idea, that the battery indicator orientates himself on the voltage of the device. Turning of the Raspi immediately brings up one more indicator light of the device.

The only objective critics I have, are those for the internet and social media. The makers did put a web page on the packaging, which is non existing! That´s poor! A very simple page, with the digital descriptions and links to their project pages as well as some technical details or maybe the story of their Kickstarter campaign, some pictures. If you raise over 600k $ from more than 3.000 Backers, you should be able to do this… And to become member of their Facebook page, which is restricted to backers only apparently, you need to enter your details of your order to get accepted. Not very open minded there as well… I know that they might have other priorities but nowadays, this is a few hours of work and for your PR in my opinion a must have.

For the rest I can not complain about the product. Seems to bee good quality, properly worked out with a lot of thoughts for some details and the speed of the campaign was remarkable!

As always I’ve added a few pictures of the device, because they always tell more than a Story.

Third step – Finally

So finally i realized the final configuration on my network. I integrated my Security Gateway into my network and i am enjoying the statistics the thing is showing me. I am fully satisfied for the moment. For sure i am hoping for more options especially some kind of protection for children or other non wanted pages. I’ve been used to Ipfire for some time, but for my private needs the USG should be doing it.

But what should i tell you? I’ll show you some screen shots which is better than any long report! Ah yeah… I just ran into one issue during installing my device. It’s default IP is in the 192.168.1.X Range which may become a problem if your router / Internet Connection is in the same range! So before i realized that i really had a hard time. But finally changing the Modem’s IP solved everything and from that on the system keeps running.

           

Second step – Make my W-LAN big

So after my start with one hotspot I ordered last month one UAP-AC-LR and this month another UAP-AC-LITE from Ubiquity. So my network now counts 3 hotspots, on 3 different floors and it covers most of my home. Maybe next summer I will reorganize everything but I am confident that the system should be able to handle my wishes ;-)

So where to start? First I needed a controller for the hotspots. My Virtual Computer could program everything but I wanted statistics to see the problems and the usage of my home. To be honest I didnt want to buy the controller. It is nice, it does its job, but I think that doing it yourself is always the best way to go. So I took a Raspberry Pi Model 3, packed everything together with a PiDrive from Western Digital I had lying around and with a little help from over here, I created the controller myself. It now runs for already some time, without any issues and the power consumption is okay. So the controller issue was solved easy and fast.

Buying more hotspots was the second step and it only was a question of time. I will have to see where I will place the different devices, but that’s for the summer and I need to get a network cable into the garden to maybe place one over there. Time will tell.

Next step in my project will be the Security Gateway (the USG) which I want to include. This should give me more detailed statistics and it should increase my security level for the connection. We’ll see that next time =)

Managing multiple WordPress Sites

So do you need to update more than one WordPress Site? If this is the case you might look around for managing multiple Sites over a singe interface. A few weeks ago I did have a look into that topic due to the fact that I didn’t want to spend an hour every month logging into various sites I keep an eye on, simply to click and update everything. So I had a look over the horizon of these programs.

I found a few but most f them were managed somehow by companies where you needed to somehow provide them your log in’s, which seems logical if you want them to update your sites. But as I am a somebody suspicious, I wanted to stay the boss of my data and so I decided myself for a tool called “MainWP”. So if you should ever consider getting something similar, you might have a look at the program.

You simply have to install the plugin on your main Site, and install on the sites you want to manage a child plugin. That’s it! No fancy registration etc. Very easy! And you stay Master of your passwords and log in’s!

The tool itself comes as a simple plugin for WordPress. They recommend setting up an own WordPress Site for the tool, which I definitely can confirm! It simplifies things and keeps it more clear and clean. Another thing I recommend is enabling the unique security ID on the “child” sites, those are the sites you want to manage over your central site. This gives your managed sites more security. I am not sure that without enabling this feature, it would not be possible for anybody to modify your site. But anyway… Enabling security features isn’t a mistake! Never!

For the rest you should simply try it out yourself. It’s worth a try! Yes there are other sites with more features and you might need to put up an own cron-job, but you stay your very own Key-Master.

P.S. Sites / URL’s have been blanked out!

Virtual Server made easy

I was shown by a colleague of mine a nice tool I wanted to share. Ever wanted to have your own cheap Linux server on the net? So did I and the prices were not so, let’s simply say, attractive! Either you get a real Virtual Server and these come starting for at least 10€ / month, but you can find prices for about 5€ / month where you get a scalable server.

The service I tried out is called DigitalOcean and it appears to be one of the most simple services in this sector. You can, in less than a Minute, create a new server, scale them up and much much more. And the best of it, you pay as you use it. Not using any space or CPU etc, means you’re not paying anything.

It’s easier than running your own Raspberry at home and not having a fix IP etc. For the fix IP you’re already paying much more, and many tools need an own IP so if you’re interested in this, you might have a look at it.

That’s the way the cookie crumbles…

Time-Lapse Project – Part 1 – The Parts

So i had the idea to create a timelapse movie and had been looking for some time to get a “Very long term” timelapse device. You can find quiet a few cameras on the market which do give you the possibility to create such series of pictures, but they all come down to the same issue: the problem of power! Most of these devices have internal batteries which need to be charged over (Micro) USB cables which in outdoor situations becomes difficult to keep it dry. Special casings might help but it always becomes a risk factor, because those devices are not ment to function like that.

The only option i found were cameras from a brand called Brinno. I had seen one before at a friend´s but what irritated me most was the fact, that these devices could not do Full HD. Their maximum Resolution was 1280×720, which is nice but the cheaper ones even only do 720p. And honestly they do not come in cheap… But i have to say, they are solid, the picture quality is okay and they do run over weeks and even month without changing batteries. So for a project without energy they are in my eyes definitely the best option!

And so i ended up in a plan constructing a Raspi-Camera with an Outdoor Water Proof Case. Finding such a thing is almost impossible! You could take an old CCTV Outdoor Case, but honestly they are simply huge! Something small and discrete looks different… So i ended up with a Kickstarter Project called PiCE which was realized in 2013. Luckily i was able to buy a “used” case on ebay. But i have to admit that i had the chance to get a case which was never really used. Only a few scratches but that´s it, it had never even been assembled.

So after having my case, i had to start planning the rest. An old Raspi B was luckily on hand, because that was the device at that time the case was designed for. I bought a new Camera and started my assembly. For the software part i chose motionEye OS, which is a nice environment if it works, easy to use with a very user friendly interface. It can even stitch your time-lapse video together! So maybe no need for post production.

That´s the plan, follow up will come next month with some problems i ran into and where i am seeking for solutions =) But that´s how it is with the Pi. It´s always work in progress.
