This was a fun Instructable to look through. Very well done with the sharp photos, clear directions, parts list, and I especially enjoyed the 'lessons learnt' portions. While I don't plan to make this, I learned about available parts and techniques for my own future projects. Thank you!
I had a space above the entry to my garage that was just begging for this project. Worked perfect for a 10x30 matrix. (boy was that a lot of cutting!) Turned out super fantastico. This shows that you can modify this instructable for probably any size matrix you want. BTW, I took the advice from comments and skipped most of the soldering by using ws2812 strips. Thank you for the great instructable.
Make Your Own 10x10 LED Matrix
Looking forward to building this beautiful project. One thing that put me off was the high price of the glue sticks in the link (roughly $48 for 64 sticks). I did a little searching and found a 5lb box (approx 85-90) 10" sticks on Amazon for under $22. Check it out here: https://www.amazon.com/gp/product/B00OBC4CWK/ref=p...

Really interesting and you're right, I had no idea humans could eat acorns. Along the same lines, are you aware of a way to process Buckeyes? I have a mature tree that drops many hundreds of them each fall. Never know what to do with them.
"Fiber Optic" LED Matrix
Here's a thought. Do the same but instead of pennies use arcade tokens! (you can buy them buy the pound on eBay.)
Really cool! Thanks for posting this link.

Leather Watch Strap: Hand Made or Laser Cut
Decided to change the digits to my favorite color...Purple. You can't see it in the photo, but the colors on this little panel are gorgeous!
Love this clock! Finally got it working today. I also was having problems with getting the esp to connect to my wifi. In my case it turned out that the esp board doesn't like unusual characters in the SSID name. For example, I had used the SSID name of ^o-0^ . My phone, laptop and everything else could connect to it but not the esp. I changed it to all letters and boom! the clock connected to my network and is now working!
Morphing Digital Clock
Nice instructable. I'm most of the way through my setup and have run into a brick wall. Advice please? My project consists of one long string with 250 leds. The problem comes in when I try to configure the E1.31 network. The instructions say to enter the total number of leds x3 into the Last Channel box. In my case this would be 750. But....you cannot enter any number larger than 512 into the box. I'm stuck. Surely I'm not the only person to run a string this long. I've ran a power injector half way along the string and am able to run an arduino string test to verify all leds light properly. Any tips or tricks to help me finish my project?

Very nice instructable! I'm also a watch hobbyist and hate to see a nice watch tossed away instead of being repaired. One comment: Using the same technique, you can replace your glass crystal with one made of Sapphire. While being more expensive than glass it is virtually scratch resistant and will look like new for a lifetime. Sapphire is what they put on most of the higher end watches.For those asking how to size a crystal for their particular watch: You measure the old one and order a new using the same dimensions. For this you'll need a digital micrometer. Fortunately these are fairly inexpensive and you can buy them on eBay. Where to buy a replacement crystal? Two sources I've used: esslinger.com and crystaltimes.net

Literary Clock Made From E-reader
Looks terrific and can't wait to build this. One concern I have. I want to place this clock in an area that does not have Wifi. Can I build it, program it, set the time via Wifi and then move it to it's new location? Or does it need a constant wifi connection to sync time?Thanks!
Your prices are a bit skewed. Had the prices actually been that high I would never had done this project. Check out my links for the LED sources on Ebay. Also I used a total of (5) 300 watt power supplies. One per truss. It's been a couple of years now but I think I had about $250 into the whole thing.
Thanks. I live in northern Minnesota and looked for the strongest and temperature resistant tape I could find. Even though expensive, I think it was worth every penny.
Yes. I have an old 12v car battery that would be perfect. You can buy solar kits at Harbor Freight that would do the job easily.
Valid point. If I were starting fresh today I may have used a different approach. For me a lot of the fun is in the research. How best to accomplish my objective. At the time, this was the best I could think of.
Wol Clock ESP8266-12E + 60 LED WS2812B Analogue Digital Clock
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 plan…

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.

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?
I'm running about 50 meters off a single power supply. No problems so far.

How to build a wood paddle board
Wow. Good point. I don't really need a diffuser. It would probably just collect dead bugs anyway.....
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.
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?
So far so good. The tape is working perfectly and other than the first few initial dead LEDs, no new ones have shown up. I have no regrets! Have fun and enjoy your efforts.
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.
Nice! I'm proud of you for doing it.
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.
Not really. I do all the work myself, paying only for materials. The entire thing was under $6000 when complete.
I totally agree. I didn't run mine in series just for that reason.
