Undercounter iPad dock

My wife and I own many cookbooks but more often than not we look to the interwebs for recipes. I got my wife an iPad for her birthday when I finally got tired of scrolling through verbose assembly instructions on an iPhone. Prior to purchasing the wonder tablet I knew that our lack of counter space left few options for placing the iPad out of the way yet accessible at the same time. I would have to go vertical.

At first I thought about modifying a COTS (consumer off the shelf) iPad case and mounting it to the face of a cabinet but I didn't feel comfortable swinging the thing around every time we wanted to get a plate.  After hitting a slight creative block, I was inspired by a couple drawer slides I found whilst fumbling around my spare parts box. I could mount the dock to the underside of a cabinet and slide it out and over the sink when it's needed. However, in this configuration, I would only have 1 and 1/8 inches of clearance to work with. Subtracting the width of the iPad (1/2"), the iPad holder (1/4") and the logically minimal width of a sturdy base (1/4")... I was running out of room quickly.  I would have to lay the iPad holder flat against the base and somehow conjure up enough space to fashion some sort of kickstand mechanism.

Knowing that I had no height to work with, I envisioned an opening in the base where the hinged portion of the dock would reside.  I also thought up notches in that opening that would later accept a couple of saw tooth sections to act as adjustable stops for a kickstand. Luckily I have access to a laser cutting table. Otherwise, cutting out the design below would have been impossible with a Dremel.

The kickstand affixes to the underside of the hinged section with a couple of brackets that were also cut out using the drawing in Figure 1. Love that laser. I made the kickstand by bending up a piece of 1/8" tubular aluminum on a vice. There was as little trial and error involved here. I had to get the leg sections the exact same length or else they wouldn't sit on the stops properly. I wouldn't want the iPad to wobble around now would I.

I made the iPad holder out of 1/16" sheet aluminum which I painted a shiny black with a couple coats of clear acrylic for protection.  This is also the case where having the right tools really makes the job easy. Having a good sheet metal cutter and bender makes all the difference. I left a little slack around the iPad to put a thin felt pad to minimize scratching but turns out the current finish is soft enough and any additional material may not be necessary.

There are a couple things I would have done differently had I owned the house. First off, building the drawer slides into the cabinet so it's totally hidden when not in use would have been really neat.  I'll shelf that idea until I put up some custom cabinets of my own.  Next, having the whole thing motorized would bring this to the next level. Completely unnecessary but cool none the less.  I had that notion from the very beginning so I designed it with that potential upgrade in mind. Though I have many more projects in mind so that will have to wait for another day.

The concept is great but the execution is not appealing. No thanks, I'll use my cookbook stand. :)
