Forgive me as I can't remember where I saw it...I'm looking for a stand for an iphone 4. It doesnt have to be able to charge in it, just to sit in it on a nightstand. It had a back on it so iphone couldnt be knocked off...
If you look at the photos on that site, you will notice that there is a missing bracing connection in image #4 down the page. In my first photo, you can see it holding the back support to the center of the structure. This is the mod. It's simple really. The original design tells u to cut away the strips. I simply keep these strips and make them into bracing connections.
TIP: Print out diagram onto a regular printing paper. Then tape the design onto your hard construction paper and then use an x-acto knife to trace the lines to be cut.
TIP2: Do not use thin paper to make this, it will be too weak to support your iPhone's weight.
Meanwhile, I effed up big time. I had two old Apple Newton supports with variable angle. Solid and perfect. Found them in the garage and, on a whim, chucked them out, thinking who needs this kind of thing. Did it mid way between the Newton death and iPhones coming out.
I like hte Luxa 2 H1 in that its adjustable so you can use it whether your phone is naked or in a case of various sizes. Can't say I'm crazy about those arms though, but its a trade off.
