Picture of GPS Shader Hood from Parts on Hand
Living in LA, there's nothing I like better than cruising around the city with the top down. Unfortunately, the open roof doesn't provide shade for my Trip Computer/GPS, so I took some spare materials and a little time and knocked out a lightweight inexpensive shade to solve my problem.

I'm afraid I thought of doing this as an Instructable after-the-fact, but figured it'd be a nice simple one to get my feet wet.

Parts:
1 Standard DVD Case, black
3 in Velcro (black or color to match your GPS
1 ft Black Fabric Tape (Optional)

Tools:
Metal or other sturdy ruler (to measure and to crease)
Scissors
X-acto knife
Sharpies (of a color to be seen against the DVD case)
Nail/Emery board/Sandpaper (Optional - if you want to smooth out the edges)
File folder and pencil (Optional - only if you want to make a test pattern beforehand)

Time:
Approximately :30 minutes, 1 Hr if you're a perfectionist.

Step 1: Designing the hood

I managed to do this without creating a pattern, but you might want to if you're worried about wasting plastic.

Remove and discard the clear plastic sleeve (and the paper insert if it is still in the sleeve.) I'm condensing all of my DVDs to slimline packaging, so I have a bajillion old-style boxes I haven't recycled yet.

Cut and remove the disc-holder panel, and "spine" piece, leaving only the front panel.

Using scissors (or X-acto knife) CAREFULLY cut inside the case and remove the "lip" from around the edge of the front panel, leaving a nice tidy sheet of plastic with two holes where the "booklet" spring clips were located.

Step 2: Measure, Cut and Fold

Apologies, but photos of the dark Sharpies on the dark plastic really weren't helpful, so I'll explain as best I can- it's a lot simpler than it sounds.

Measure the top of your device from side to side. Center that measurement on the back of your plastic piece, and draw lines representing the outside edges of your device with your Sharpie for reference; you'll fold along these later to create the main part of the hood. I put my device on the plastic to trace, as that was fastest.

Draw an angled line from each of the Sharpie lines from the outer edge of your hood to the outside (what used to be the top and bottom of the case) edges of the DVD case; I left a tiny bit of edging there for strength, but it isn't really needed. You can see two notches in the sides of my cover that were where the booklet spring clips were.

Measure 1.5 Inches from the back edge of the plastic to cut out enough plastic to leave two connector flaps on either side. Again, I traced my GPS as it was quickest, and allowed me to match the rounded contour of my particular device.

Cut out all the outside edges of your design with the sharp implement with which you are A) most comfortable , and B) least likely to injure yourself. My lines are straight and basic- feel free to get fancier if you want something different.

Next, simply make four folds - two for the tabs, two for the hood. All go to the inside, as shown in my image. I used the measuring grid inside the plastic to help keep my lines crisp. You can see how my folds show stresslines from bending- you could minimize that by scoring the bends first, but I did mine without as I felt it would be stronger in the long run.

Step 3: Attaching the Hood

Once you have your lines creased the way you like- test fit to be sure everything worked as you'd hoped - flip the hood over 'face up" and break out the Velcro.

Cut two pieces each of hook and loop to fit the tabs on the hood. I used peel-and-stick Velcro, so I attached the hook side to the hood, with the loop sidestill attached, then pressed it to the GPS to simplify lining them up and get a perfect fit.

If you're happy with your cutting, you can stop right here!

Step 4: Bit of Polish...

Because I'm putting this in an Art Car, I thought I'd polish it up a bit. I took some 2" wide matte fabric tape and covered the sides of the hood, folding it over the top, to hide the white stress marks of my creases.

I lightly sanded my edges with a nail board to round the sharp edges, then ran a black Sharpie around them to blacken them up.

Finally, I gave the hood it a weigh-in on the scale, and it's a tidy .75 of an ounce. This means it won't really add a significant amount of weight when I return it to my windshield mount.

Plus, 'cause I'm a geek, I added some dressing to make it more futuristic and hide the brand name.

Step 5: Test and Wrap Up

Time for a test! Car top down, I popped the GPS in by itself, and then with the hood in place, and saw the difference I'd hoped for; It works perfectly! And doesn't look bad with all the other mods I've made to the car, as it functions as my "targeting computer."

PROS:
Light and Sturdy
Inexpensive
Easy to make

CONS:
It MIGHT look a little dorky. D:

I may now have to build one for my stereo headunit...

Nice build..simple, but effective..

I like the idea, I have a ton of empty dvd cases laying around. But what I find more interesting is the Mods you have done to the car. I would personally like to see a little more of them and some up close shots. And the R2D2 on the back of the other car is awesome!
I'll second this one.

oh awesome! great job on your first instructable! do you find that this obscures your vision at all (or hits your head while you are driving?)

Thanks! It's largely out of the way, and isn't any more intrusive into the cabin than the top bar of the windshield is.

This is also just as functional with the GPS mounted closer to the dash, where most people put theirs. I have mine in an odd place because of the "Star Wars" context of the car. But the shade is created relative to ythe unit, so works anywhere your preferred mounting spot is.
