Like many schools, ours is trying to put an iPad into the hands of every student.  For our seventh grade, that's over fifty iPads.  As our middle school is multi-age, in a year we will have iPads for every seventh and eighth grader.  Soon, we will have to store and power over one hundred iPads.

The cost of an IPad cart is anywhere from over a thousand to three thousand dollars.  Looking at their capacity, we would need to buy anywhere from three to five carts that are currently on the market, depending on the cart.  While various grants have allowed us to stock up on iPads, they won't pay for the cart.  Or five.  Our school's budget is shrinking, so we needed a solution that was practical and cheap.

I would have thought that, with the popularity of iPads, cart plans would abound.  No.  There is one plan, which was very helpful in organizing the Ipads.  John Umekubo is the Director of Technology at St. Matthew's Parish School in Los Angeles and writes this very helpful blog entry here.  It will teach you the guts of the beast.  Other sites talked about using dish racks and such, but they weren't secure and middle-school proof (I did adopt an old desk organizer for my own personal electronics).

This design is four cabinets, each of which holds nearly 30 iPads while charging ten at a time (more on power and syncing later).  They are designed to sit on a counter, although caster wheels could be added and be secure from crimes of opportunity (anyone who really wanted our iPads could get them, and you can make them more secure, I'm sure)..  The total cost was $400.00, including locks.

Throughout, I offer up considerations and lessons learned.  On the last page I have included other brainstorms.  I am sure you will only improve on what I've done with these prototypes.

Step 1: Materials

I built four carts.  Adapt to fit your needs.

Four 19/32 CDX plywood.  If you plan well, you can actually get away with three sheets.  CDX is cheap, but pretty ugly sitting on the counter.  If I had it to do again, I'd spend the extra $80 and upgrade to AC or something with a nicer finish, or have planned better and used only three sheets.

Five 1"x10"x10' pine boards

Two 1/4" Luann 8'x4' sheets.  Nice stuff.

1lb of 1 1/2" finishing nails.

1lb of 2" sheet rock screws (wood screws would be fine, but I had these already).

100 1/2" #6 wood screws.  The hinges and latches came with screws, but the screws were a tad too long for the thickness of the wood so I had to buy the wood screws.  Your results may vary.

Wood glue.

Eight hinges.  Note that some hinges have a removable pin, which is not what you are looking for if security is an issue.  I went cheap and got 3" narrow hinges.  They came in two-packs for under $5.00 each. 

Four latches.

Pack of four locks that have a common key..  Master Lock sells them and it allows for other teachers to open any of the iPad carts.
Gun safe is... Safe, but the racks are the key part for students.<br><br>Insurance is an issue, and our school's just told us so. Still, works great.
<blockquote>I figured if I removed the drawers, I could build the shelving inside and fix up some type of door.</blockquote><p>Actually you might want to leave the drawers in place and just add the wooden rack to the inside of the drawer. That way you can recycle the drawer slide hardware. Drill a few vent holes in the back and you're all set.</p>
Nicely done! And thanks for the nod. Hope all is well and that your hard work has paid off. ;-)
Try getting a powered USB hub. You can get them for cheap on dealextreme.com just make sure it's powered.I've seen ones with more than 30 ports.
Nice idea. My school has an iPad for every student and they are in these huge metal trolleys that have slide-out trays with cushioned pockets and in-built chargers.<br> <br> A quick google search and I found ones pretty much the same as my schools ones, around &pound;3500 ($5427!)<br> <br> Anyway, nice Instructable.
Actual building and box, fine. <br>The theory/intended usage, crazy. <br> <br> <br>I cannot imagine anyone storing this amount of valuables in a wooden case. <br> <br>I could see the file cabinet idea working though. A nice heavy one that locks (and added brackets with padlocks as needed) with heavy-duty wheels. And a school district might just have a few not being used. <br> <br>There would still need to be some way of making sure someone couldn't wheel it right out the door in a break-in.
I am deferring to my administrators on this one. They may bolt the whole thing to a counter. Our local high school once had an entire laptop cart (securely locked!) wheeled out the door and into a waiting van (and caught them selling them on eBay, where they helpfully posted the serial numbers). Overall, though, technology is scattered all around without incident. <br> <br>The screws alone can easily be worked out of the latches and hinges, but the local concern are students and others simply walking away with one--the crime of opportunity rather than premeditated theft. At one point my design included pegboard sides, for ventilation, and they were fine with that even though a first grader could have punched a hole through it. But our community is small and, for now, this will do. If not, I would be more concerned, too.
I was thinking a literal &quot;smash and grab&quot;. <br> <br>Not to mention for liability or insurance purposes in the event of a fire/etc. <br>A gun safe should suffice.
