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.

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…

pi-top CEED

After a few month of waiting for my second Crowdfunding Project, i finally recieved my pi-top CEED. I aditionally backed the Speaker so this was an Option in the funding. So wanted to Review a litte bit this Project which i followed from the beginning on.

First i have to say that the Initiators always kept a very good contact to the funders! They posted on a regular Basis News of the Project and so as a backer you were always kept informed. This was especially interesting due to the fact that at some Point they ran into Problems and had difficulties to stay in the schedule. In my opinion very positive and so as a backer i always felt myself very comfortable even with some weeks falling back! I never got the idea that my Money could get lost.

Another nice touch was that they posted on a few occasions Pictures of what we could expect as a result.

As the package arrived at my home i have to admit, that it was very well protected. The packaging itself was as already seen on the Pictures nice and trendy.

Using the device itself… Inserted the SD-Card which was provided and connected the Raspberry-Pi (i did buy it separately) and booted the device up. No Problems with defective Pixels for my device and the Speaker worked after the Installation as it should! Okay… It is not only the physical Installation but you also Need to install the Drivers. Inside the package you could find the How-to or you can read it from the page under this link.

Finally i have to say that the Linux-OS package provided from them is not my favourite… It is quiet Special and has apart from the standard Desktop a Icon based second Desktop. Apparently invented for Kids or Linux-Newbies this should do it work, but for People who are used to Linux not the Thing you want… I will try to get more into that distro and see if it is what i Need. Otherwise i will stick to as usual Distro for the Raspberry.

Anyway… The device itself is of very good Quality in my opinion! I got a green one and the Color is flashy =D I´m lovin it! The idea to hold the Raspi with Magnets is another glorious idea! The only negative aspect is that inserting any USB device may result in misplacing the Raspberry… By being careful it should work.

Roundabout it is a nice Piece which i got for a reasonable price by being a backer.

Timelapse Video’s by Raspberry Pi – motionEye

So as some of you might know, i am a huge fan of the Raspberry Pi. And a few weeks ago i was looking for a script to handle an automatic movement detection for the Raspberry Cam. And i fell on a tool called motionEye which finally did even more than i expected.

So after my first testings and looking more into the configuration i found out that you can even realize time-lapse videos with the device itself, without the need of any other program. And what makes it even more interesting are the resolutions. You might find cameras which realize time-lapse Videos but the resolution is always weak.

Recently there was a project called Enlaps on Kickstarter where you could by a nice future product for timelapse video but the price was not really my idea for a start into that world. So i wanted to try out the limits of this Raspberry Project and here is my first video.

One thing which needs to be said: The camera is everything! So the motionEye system gives you the possibility to use the Raspberry Camera but you can also use network cameras and USB-Webcams. So a cheap possibility to try out various stuff.

So far i tried out a „Waveshare Raspberry Fish-eye 5MP“ and a cheap USB-Cam „Logitech C270 1,2MP“ and as i said the camera is everything! And i will also try out the the PiNoiR module from Raspberry itself, but it is apart as it was developed for infrared photographic.

Anyway… The video shown below was realized by the Waveshare camera without any light and so during the night there were no rally good pictures. That’s the next step i have to experiment with. The program itself can create pictures with a rsolution up to 1600×1200 pixels but this is still in progress i think.

So if you are planning on such a project or need a motion detection software for a DIY surveillance system, you should give motionEye a chance. My respects go out to the programmers who did put a lot of effort into the project allready.

Ewéi verschiddener vun iech villäicht wëssen, sinn ech een risegen Fan vum Raspberry Pi. Virun puer Wochen elo wor ech op der Sich no engem Programm deen Bewegungen automatesch erkennen géif op der Kamera vum Raspberry. An dunn sinn ech op een Tool gefall wat motionEye heescht, an wat souguer méi konnt wei ech un sech wollt dermadder realiséieren.

No deenen éischten Tester mat der Configuratioun hunn ech eraus fonnt dass den Programm souguer Timelapse Video erstellen kann, ouni dass een dofir elo nach een extra Programm bräicht. An wat en ausserdeem nach méi interessant mëscht sinn d´Opléisungen. Et fënnt een Kameraen déi sou Video realiséieren, ma d´Resolutioun ass ni wierklech groussaarteg.

Rezent wor een Projet deen Enlaps genannt gouf op Kickstarter wou een flotten Produit presentéiert gouf, vun enger Kamera fir Timelapse Videoen ma den Präis wor mir einfach ze deier fir an déi Matière eran ze klammen. Dowéinst hunn ech elo och den Raspberry Projet ausprobéiert fir mäin éischten Video.

Eppes muss fir ewech gesot ginn: d’Kamera ass alles! Den motionEye System gëtt engem d’Méiglechkeet dem Rasberry seng Kamera ze benotzen ma et kann een och Netzwierk Kameraen oder USB-Webcam’en benotzen. Also eng bëlleg Solutioun fir divers Saachen aus ze probéieren.

Esou wäit hunn ech d’„Waveshare Raspberry Fish-eye 5MP“ ausprobéiert an eng bëlleg USB „Logitech C270 1,2MP“ an ewéi ech schonns sot, d’Kamera ass dat Wichtegst! Ech wärt och d’PiNoiR Modul vun Raspberry ausprobéieren, ma et leeft ausser Konkurrenz well et gouf fir Infrarout Photograpie entwéckelt.

Also… Den Video gouf realiséiert mat der Waveshare Kamera ouni zousätzlech Liicht Quell an dowéinst woren während der Nuecht keng wierklech gutt Biller do. Déi Tester kommen an der nächster Etappe. Den Programm kann Fotoen realiséieren bis 1600×1200 Pixel ma ech denken do ass nach Spillraum no uewen.

Wann dir also un engem ähnlechen Projet schafft oder Bewegung Erkennung braucht fir een DIY Iwwerwaachungs System, dann sollt der motionEye eng Chance ginn. All Respekt fir d’Programmateuren déi schonns ee Koup Aarbecht an den Projet gestach hunn.

Meischen Meischen – Toys for boys

A few days ago, i received my newest toy. It is a so called “mouse jiggler” which means it is an USB-Stick which simulates a mouse. The best with it is that you can even program it to do specific tasks (simulating pushing keys or to click somewhere).
The main idea is to keep an computer alive so that no screen saver or power saving program blocks tasks from being executed.
Nice toy for boys (who need it)…

Virun puer Deeg hunn ech meng neisten Spillsaach kritt. Et ass een sougenannten “mouse jiggler” wat een USB-Stick ass, deen eng Maus simuléiert. An deen Stick kann souguer programméiert ginn fir spezifesch Aarbechten aus ze feieren (op Platzen klicken oder Tasten drécken).
D’Haapt Iddi ass fir den Computer dorunner ze hënneren dass Screensaver usprangen oder en an den Rouzoustand geet, esou dass Aarbechten blockéiert géifen.
Eng schéin Spillsaach fir Männer (wou et brauchen)…
