Kano PC, a company apparently dedicated to building inexpensive computer blocks to familiarize children with hardware and coding, has teamed up with Microsoft to offer a Windows 10 laptop to assemble that kids can assemble themselves.
Historically, building a PC was a difficult undertaking. At the time when I was a kid, finding a village blacksmith who owned the proper molds to mold the PCB to mold a motherboard was challenging. Once you have enough copper wire from the Ogre pit, you need to shred a good Mountain Performance depth clock and sacrifice it to pass to the three gods of peripheral support: IRQ, DMA and I / O range .
If your prayers (and your questionable driver code) were accepted, a new one would be added to your delicate stack of magic and circuits. Otherwise, run the FranticRepair function, making an all-night effort to restore the family computer in the state it was in before Your parents went to sleep the night before.

Very well JamieIt was not really remove that bad. But building laptops has always been really difficult. This type of simplified construction kit will not give you a high-end system, but a way to introduce children to the idea of building their own own system to carry around the house and inevitably break, it's a good idea.
The technical specifications on the Kano PC include:
The device will work under Windows 10 S – the locked variant that should not be a problem with a device like this – and comes with some Kano-specific included applications, such as How Computers Work, Create Artworks Art, Kano App, Paint 3D, Kano Projects and, not to touch, Microsoft teams. (Seriously, this is a feature of the software listed).
In kits, however, the idea of building a small laptop as a child's system is appealing. The $ 299 Kano PC will only be available in October, but if it is up to its appeal, it may be a day off for a child interested enough to start learning how to build them.
It is unclear whether this version of Windows 10 S can be converted back into a real version of the operating system as are other computers running 10 S. If that is the case, it should be act of an excellent little computer for the first hands. Variants based on Linux and RBP are also available (and Kano builds different kits designed for these spaces), so that users have options depending on which operating system you prefer. Of course, there would be nothing s & # 39; stopping Someone is trying to load Linux into this case (and I'm sure someone will try), but the value-added software included by Kano is probably supposed to be a reason to stay with the Microsoft loadout. .
While I was working on updating our articles on home video surveillance systems, I purchased one of Nvidia's new Jetson Nanos. When you play with the $ 99 chart and use it to recognize objects using various cameras, it seems like a good starting point for a handy little NAS device. It consumes very little energy and is portable. In addition, the integrated GPU has a larger AI capacity than most larger NAS units, and the Nano comes with a ton of pre – installed AI tools. So for those who want to play with their own movement or person recognition, package or pet, this would be ideal.
Nvidia really facilitates the installation of the Nano. All you need is a microSD card and a computer to flash the L4T (Linux For Tegra) image. Technically, all you need is 16 GB, but the system takes the most. So I used a high-speed 64 GB card. Once you're connected to the keyboard, mouse and monitor, just plug in a micro USB power source to use Ubuntu 18.04. A wide variety of AI tools and demo apps are preinstalled for you.
You can certainly work directly on the Nano because it offers a decent interactive performance, but I found it more convenient to use Linux on my main Windows machine for the connection. Thanks to X Windows and Web server-based applications, I could do almost everything from my machine and I do not need to go to the Nano. At first, I tried to get by with Hyper-V, but it's really not ideal for this use, because I wanted to do a remote development to test the Linux system, then deploy it on the Nano. I went to Oracle Virtualbox. I think VMWare would be even better since it would have improved support for USB devices, but Virtualbox is free and has worked well. Of course, a native Linux host would be ideal, but I could do what I needed without turning on a dedicated Linux desktop.
The Nano comes with a central processing unit, a graphics processor, a random access memory (RAM) and comes on a network card with many options for I / O. The Nano has an Ethernet port, but if you want to use it with Wi-Fi, you have to add it yourself. It is quite easy to add a Wi-Fi + Bluetooth card via the M.2 slot, but you can also use one of the four USB ports. For heavy computing, you will also want a 4 amp, 5 volt power supply with the proper connector. And a fan. All this is easy enough, and Nvidia has usefully provided links to compatible parts on its Jetson Nano Developer Site.
There are now 3D printable cases that you can make yourself or print a service desk. Several are related in the Pregnant section of the excellent ELinux Nano website. Commercial efforts to create Nano-based NVRs have added multiple Ethernet ports via M.2 adapters, but for a home-based solution, provided you have a way to get your cameras on the network (or you can live with a couple Models connected by USB), this is not necessary. An additional device you will need a storage drive for recorded videos. Almost all SATA drives are usable, but for performance and portability, an SSD drive would be better.
Fortunately, I had the ideal SSD at hand. Seagate has been introduced to the optimized NAS Ironwolf 110 SSD and I had an examination unit to use. Used with a box with its own power supply, it worked perfectly, the only drawback being that it would not work properly if it was only connected to a USB port. As an alternative, I connected an SSD M.2 drive that was also working but was of course not optimized for a NAS workload.
The amount of storage you need depends on your cameras. their resolution, and how long do you want to keep the recordings. I've successfully tested a home NVR on a 5-bay Synology DS-1019 + NAS with a 2-disk RAID 2 array. I've therefore used a 2 TB Ironwolf 110 SSD drive. The small size of the SSD means that you have the base of an ultra-portable video surveillance system. Seagate's new Ironwolf 110 SSDs are also optimized to handle the typical heavy workloads of a network server, but you can certainly use something less expensive: the M.2 disk that I had used before was the one that I had taken out of my Dell laptop a bigger one – if you are trying to cut costs.
Configuration tipsFirst, once you've set it up, you do not need to connect to the keyboard, mouse, or Nano for most things. You can run it remotely through an SSH session or another terminal session and use web interfaces to manage the NVR or a remote GUI such as X Windows. Secondly, I recommend you make a backup of your system once you wish. A simple way to do this, if you're using Windows, is to use the free Win32 Disk Imager software to create an image of your microSD card.
There are many good NVR software solutions. The difficulty with using Nano is that it requires software that does not run only under Linux, but that runs on an ARM processor. In my case, I did not want to spend the time needed to create a solution from the source; so I looked for a free solution that would not work. That led me to ZoneMinder. ZoneMinder is easy to install and has a native Web user interface. It is easy to manage from anywhere on your network. It is flexible and powerful, but I can not find the intuitive user interface down.
There was also a small problem in the version that I used with Nano (running 18.04 Ubuntu L4T) when I was trying to use the Probe feature. I had to manually enter the details of the camera. This sounds like some kind of strange library version problem which, hopefully, will be fixed as the Nano becomes more popular.
Most of the big investment in home security cameras goes to non-NVR cameras such as Ring (Amazon) and Nest (Google). Personally, I think it's a terrible trend, because all these cameras could easily support RTSP and ONVIF, but the companies that have them behind have chosen to charge you to watch your own video. That said, fortunately there is a thriving market of IP cameras that you can use as you wish.
The first camera I used with ZoneMinder on the Nano was the Honic 4K, powerful but not expensive. I will write more about this in our update of our roundup of security cameras, but in short, it is an IPE 4K outdoor IP camera for only 80 USD (Note: j & rsquo; I bought one for $ 80 when I started working on the items two weeks ago, but it is now $ 104 on Amazon, so YMMV). It was not easy to connect the camera to ZoneMinder without access to Automated Probe functionality, but Honic's tech support staff sent me back with detailed instructions.
Assuming you use ZoneMinder, you add cameras as Monitors. To test them, you can simply configure them with the action "Monitor". But to start recording a video, you'll want to change them to "Mocord" or "Modect". Modect gives you the ability to detect motion in specified areas. At this point, as a person who runs a home video surveillance system for several years, I highly recommend you to continuously record if you can.
For me, the best strategy if you have a system capable of recording continuously is to record everything and then highlight the motion events. There are many good reasons to save everything, but the most important thing is that you can be sure of things that have not happened. In our case, the most common use of our video footage proves that a delivery has never been made. A corollary is that you can be sure that if something has happened, you will have a record. If you only record motion events detected, you can never be sure to have all the information.
That said, it is really useful to be alerted only when motion is detected and to be able to quickly advance through the records to see the detected events. If you want to do programming, the Nano is the ideal tool to code a smart artificial intelligence to detect the events that interest you and to manage them specially. The Nano is powerful enough to run both my ZoneMinder installation and the AI-based detection applications that I use with a Logitech USB web camera. So you have plenty of time to add custom features that you can understand to code.
The user of Reddit TheIncorporeal has exactly thatand the result is quite aesthetic – especially if you are a technology geek.
Of course, it is not easy to give the impression that it looks like, but TheIncorporeal has some tips for doing it. The short version is that you have to find the right frame and arm yourself with patience; but check out his comments below for more details.
He did the same thing with several iPhone models, including an iPhone 5, 4 and 4, and the results are just as beautiful.
Since almost everyone has a dead or almost dead phone lying around somewhere these days, finding equipment with which to work should not be too much of a problem. Now all you have to do is work, and your walls could be adorned with pretty works of art representing part of the phone in no time. If this sounds too complicated, you can contact TheIncorporeal directly via this email: email@example.com. He transforms his idea into a company and carries out custom work.
