Great instructable. I had a lot of fun making it this weekend. I did a few things different as you can see in the photo. I don't have access to a 3D printer so I just used hot glue to mount the laser and Arduino directly onto an old PC hard drive. This gives it a heavy, solid base. I had a few Arduino Nano's on hand and they work perfect for this project. Finally, I didn't want to go battery power so I found an old 5vdc wall wart and used that instead. Note: if you go this route, you'll want one that puts out 1.0 amps or higher. One last thing, I bought a pan / tilt housing with servos on ebay for under $15. https://www.ebay.com/itm/DIY-2-Axis-Arduino-Pan-Tilt-Mounting-Kit-and-2-x-9G-Servo-with-Gear-Mounting/222293251320?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649I pl...

Again, great job! I really appreciate your work and uploading this project.Ken
Nice project. It would be really helpful if you posted the schematic of how everything is connected. It's really tough to figure this out just from your photos. Thanks!

What a simple, fun project! Thank you 'dpeach'. Took me about a half hour to solder the wires together and install. I used 3M outdoor tape to attach to the underside of my trunk. This stuff works terrific. 30 inches of white LEDs light up my trunk like a beacon. Superfantastico! I'm going to look closer at this and my other vehicles to see where I can add more lights.

I'm running about 50 meters off a single power supply. No problems so far.
If you are only using a single strip, an option is to buy aluminum channels with covers like these. I bought a set and they're terrific.http://www.ebay.com/itm/10m-10pcs-1m-led-aluminium-profile-for-10mm-5050-5630-3528-strip-led-channel-/252827312089?

Wow. Good point. I don't really need a diffuser. It would probably just collect dead bugs anyway.....
In step #6 I said "You can get them from any of a hundred vendors on ebay. Do a search on: 5M 300LEDs SMD 3528 5050 5630 3014 RGB Flexible LED Strip LightsIf given the option, choose the 5630 non-waterproof variety. At least that's what I used."I felt that was pretty clear.Regarding the computer power supplies. If you are at all worried about insurance coverage in the unlikely scenario where they burn up your garage, make sure you use ones that are UL listed. I am interested in learning more about white reflective half domes you mention. Would you please post a link?
I agree. I've noticed that the color quality varies from strip to strip. But in my case, it's a freaking garage so I don't care. You may also be right about the life span, but again, it's a freaking garage. I have the lights on for maybe 30 minutes per week. For me, the cost savings outweigh any negatives.
One of the computer power supplies I used had a noisy fan so I just clipped the wire. I did it an an experiment to see how hot it would get. The results? After an hour, it's no warmer to the touch than any of the others. A year later and it's still holding out just fine.
Neat project. I think it will be a fun winter project for me and my cat. Here's an idea that would speed up the movement and extend the life of the servos: Instead of mounting the laser on top of the servos, mount mirrors on each one. Then mount the laser in a stationary position and point at the movable mirrors.

I haven't added a diffuser, but am thinking about it. There is nothing ready made to fit over trusses, but I think a guy could take a diffusion panel, cut it to width, then use a heat gun to form the panel over a 2x6. I'd like to do it, but not sure if it's worth the effort. The LED strips only get slightly warm. The outdoor tape is working perfectly.I'm guessing I saved easily $2000 - $3000 over a commercial product. Look it up. Commercial LED lighting is crazy expensive.
The heat dissipation is really a minor issue as the LED pixels are barely warm to the touch. The L-Brackets would certainly simplify the project and you most likely wouldn't need to buy the expensive outdoor tape.
Nice! I'm proud of you for doing it.
I totally agree. I didn't run mine in series just for that reason.
Are you maybe trying to use a Laptop power supply? Those usually run at 19vdc. Most electronic devices (LEDs etc) run in a voltage RANGE, meaning that a LED designed to run at 12v might operate just fine from 10 - 14 volts. I haven't researched the voltage range that these LED strips run on.
The garage is another story all in itself. 1.5 years of miserable work but now I finally have the garage of my dreams.
I'm using 5 PC power supplies for this project. One for each of my trusses in the garage. I run about 7.5 LED strips off of each PC power supply. So far so good and the PC power supplies are not even warm to the touch.
Amazon. See the link on the last page of instructions.
One idea was to use a V shaped metal flashing but my local building supply store didn't carry it. That honestly would have been a pretty good idea. The metal would act as a heat sink and the reflectors would look pretty cool.
You are absolutely right. I could have cleaned up all the unused wires but my power supplies are tucked away in the eaves of the garage. Out of sight, out of mind.
Attaching power at both ends is redundant. It works, but it's not required. The purpose of the dual wires is that one LED strip has the ability to power the next one in line.
I did notice the option of buying the 24v versions, but I have free 12v power supplies so...
Excellent idea. I could have pre-built them in the house during the winter months and put them up early spring.
Very low heat. Slightly warm to the touch. Not a worry at all.
