Have A Promethean Board Tethered To Your Teacher's Desktop Computer?

Last summer, we installed Promethean Interactive LCD Panels in all our middle school classrooms.  This purchase and subsequent installation was all approved and arranged by my predecessor and frankly I wasn't all that sure about the screens.  I had much more experience with traditional projectors and, more recently, interactive short-throw projectors and I was quite please with their performance in the classroom.  Regardless, these boards were coming and were going into the classrooms.

Well, it wasn't too far into the school year when I did a full 180 degrees on my opinion of the boards. The teachers really took to them and embraced both the hardware and software aspects of these devices.  There are many advantages to them but one of the biggests advantageously different aspects is the fact that they are clear and highly visible from the back of the classroom and with the room lights on...and even when the bright sunlight makes its way into the room as well.  10 touchpoints and virtually no need to regularly recalibrate the device are among the other advantages of the screens over traditional projectors.

A challenge associated with the installation of these screens surfaced shortly after the school year was underway.  You see, all of the returning middle school faculty had an opportunity during the last school year to discuss classroom layout and screen placement with my predecessor.  However, our faculty who are new this year, obviously, did not have that same opportunity.  So, about a month into the school year, one of our new faculty wanted to rearrange her room to better accommodate her teaching style, and she called me about the Promethean Board.  Not to move the board but she wanted to move her desk.  Now you might ask, what does desk placement have to do with the interactive screen, right?  The Promethean Boards require a computer to be attached by HDMI and USB, the "brains" behind the board and how it is transformed into basically a giant wall mounted tablet.  To accomplish this connectivity, the screen installers had run wires both through the walls and/or in conduit to each teacher's desk to connect to the computer...which means she couldn't move her desk without rewiring the screen connections.  A problem.

I studied the situation for a moment and said, why don't we just mount a small form factor computer to the back of the Promethean Board?  Upon further investigation, it turns our Promethean actually sells an Android-based device for just such a purpose.  The problem with the Promethean computing device is that it does not run Promethean's own ActivInspire software, something the teachers had come to rely on fairly extensively.  Enter the HP 400G2PD ProDesk 400 G2 Desktop Mini PC.  This small form factor computer has roughly the same tech specs as the teacher's all-in-one Dell device the screens were originally tethered to.

  • Design that delivers high availability, scalability, and for maximum flexibility and price/performance


We purchased one of these devices to run as a trial and it has performed very well.  We recently paired it with a Logitech Wireless Touch Keyboard K400 Plus with Built-In Touchpad so the teacher does not have to rely on the on-screen keyboard to navigate and viola, a solution that allows the teacher to again have the freedom to set up his/her classroom as they choose.

We will be equipping our lower school and early childhood classrooms with the Promethean Boards this summer and will fit them all with both the HP 400G2PD ProDesk 400 G2 Desktop Mini PC and the Logitech Wireless Touch Keyboard K400 Plus with Built-In Touchpad.  Additionally, we will go back and retro fit all of last summer's screens with the same two devices.

I highly recommend the addition of these two devices to any interactive classroom screens.

Enjoy!!

Struggling With Poor Wireless Speeds On Older or Non-Integrated Card Devices?

We have a number of all-in-one computers on our campus, many of which are in our library.  These Dell devices did not come with internal wireless cards so we had added USB wireless devices to them a few years ago.  While these machines are in a common space within the library, we often had faculty using them when their classrooms were otherwise engaged with some other activity.

Over the  last several weeks, we received a number of complaints about slow webpage loading and the like.  My tech support folks and I would check the machines following each ticket and would often find the speed tests to be "reasonable".  Yet a short time later, we would again hear rumblings that the device performance was far less than optimal making the computers difficult to us.  Again, we would follow-up with speed tests.  And then, over time, we began to notice the speed tests became more and more inconsistent.

One day when one of our faculty was using one of the computers while I was nearby, …

Chasing Down The One-Off Network Anomaly

Most hard-core network wiring tasks are best left to the professionals.  However, the occasional cable run or the random cable end that gets damaged or even tracing a cable run is hardly worth a) calling someone out and b) waiting for a day or so to get it fixed/done.

Now if you do this kind of work professionally, you absolutely must invest in quality equipment that you can rely on day in and day out.  However, for those of us "closet" network guys, we need an array of tools that work fairly well but don't cost us a fortune.  And since I also do this kind of work around the house, I am inclined to make these purchases personally but have the tools handy to do small jobs around campus as well...another reason to be budget conscious.  Now you could buy a toner, cable tester, crimper, punch down tool, wire cutters, etc. separately but you're likely still going to spend over $100 or maybe even more.
