In answer to your question chris (although a little late..).
In the video was trailing a FAT client system I have been working on for the past few months based off LTSP.
It is better explained in a few of his other videos (which have now been removed :( ).
Project can be found here – https://github.com/gbaman/gv资源-LTSP

One big key thing about it though is that they are FAT clients!
Fat clients mean all the processing is done on the pi, also with the added advantage then of having direct access to GPIO and camera module.

It isn’t obvious how he’s configured the server. If I had to guess, he’s probably followed this guide to set up a terminal server:

gv在线观看 PI LTSP How-To

So are you saying you have set up a LTSP server, and the Pis are running as thin clients? If they all log in as the same user, won’t they overwrite each other’s files?

Though we use Debian-edu here, I decided not to run the Pis as thin clients, so that kids would have responsibility for their OS and not just data (they have their own Pis).

I have bundles of cables coming up to the desk (the towers are on the floor behind the desks), including 3 usb extension cables, into which are plugged the kb and mouse, with the third for pendrives.

When kids switch from class computer to Pi, they unplug kb and mouse, and find the HDMI, micro usb and LAN cables coming up to the desk. Like you, I use VGA from monitor to tower, so the HDMI cable is free, and I put in an extra LAN cable per desktop. At the end of the lesson, they unplug the Pi and put the kb and mouse back into the extension cables, which is very fast and simple.

A brief write-up would help a lot. Your video is long and its hard to find technical details from it. Thanks for letting us see your lesson.

I think the questions have more to do with, can you have to gv在线观看 Pi’s, that use the same flash drive (whicch if the only storage device that would have to be a yes), allowing you to leave each plugged in at a given location. Then you take all your data with you in your pocket and use them without having to do anything but plug and unplug your usb stick…

I assume you run the Pi’s over an isolated network?

Reason I say this, is because I use a RPi, but only have to plug in a WiFi USB which cost £3. It connects to the network and is assigned a static IP via DHCP through the router.

I can then connect to it with a VNC Viewer (lookup TightVNCServer for installation on the Pi) and I can also use SSH.

This all means that I do not need to plug in monitors, keyboards and mice. I simply plug in a Power Supply and connect via IP when the boot process is completed.

Brilliant!

In the video the pupils are taking the gv在线观看 Pis in to class and swapping the keyboard from the PC into the gv在线观看 Pi.

I’ve had gv在线播放 with swapping PCs for gv在线观看 Pis through running Code Club in a school using gv在线观看 Pis. The way I dealt with it was not as easy as how Ben dealt with it, as I was using a shared computer room which I needed to leave back in the same condition as I found it. I would spend 15 to 30 minutes (I got faster as it as the term progressed) unplugging all the cables from the back of each PC and plugging them into the appropriate gv在线观看 Pi, then in reverse at the end. This was OK when I was able to get into the room in advance, but did cause a few minutes delay to the start if a class was using the room up to the last minute.

I don’t think there is much risk to the connectors if handled correctly – they should take a lot of connections / disconnections before wearing out. The problem that Ben gv在线播放d with the mice is more likely due to cheap mice getting knocked around in the storage box. As these are low cost it’s probably worth taking a hit in the cost of replacement every now and again, but I understand how frustrating it is not knowing whether it’s a problem with the Pi, the power, the SD card or a peripheral especially when you’ve got a full class wanting to get on with the lesson.

One of the biggest problems I had – which I didn’t actually find the cause of until late in the term was due to the HDMI to DVI adapters not fitting some of the gv在线观看 Pis cases I was using. I was using adapters on the gv在线观看 Pi so that I could swap to the DVI cables that were plugged into the back of the PC. It was only a few that had this issue and only certain adapters (most were effected, but I had two adapters which were a thinner and longer which worked). The reason it was so hard to identify the cause was that the adapters sort of worked initially – in that a signal would be going to the monitor and so it would look like it was booting correctly, but then when it reached the point to detect whether a HDMI monitor was connected then it failed to detect the monitor and switched to Composite mode. Although I think the latest NOOBs would help here as it defaults to HDMI even if no TV detected.
