Lazy Grid Clock
Description
<b>Update 04/2020:</b> Finished a redesign of this. It's essentially the same but is much easier to build. Less parts, less screws. So if you're thinking about building this you might want to wait a few days... Here's v2 of this thing: https://www.thingiverse.com/thing:4263318 --- So here it is, finally. My first project using a single led strip only... xD If you're looking for a bigger grid and don't minder some soldering, please have a look at this one: https://www.thingiverse.com/thing:3433644 <b>Update:</b> Added a Front Frame which can be mounted to hide the screws on the front (and change appearance/color of the whole thing). Have a look at the instructions further down below. -- A few months ago I uploaded a LED grid. But it seems like people aren't using it for own stuff most of the time - instead they use it as a clock using the supplied example sketch. That's totally fine - it's just not, what I had in mind when building it. :D 24h format is only supported if built with an extension and most of the time about 50% - 65% of the leds don't do anything. To fix these "problems" I created this Lazy Grid Clock-Thing. Features: 1. Single continuous led strip (83 leds) to create a 7x11 pixel matrix 2. Fewer parts than before 3. Even less solder work 4. Customizable to a certain degree (front bezel height/color) 5. Still usable for own projects (lots of screw holes to connect it to other things) 6. If used as a clock only, there's much less LEDs wasted than using the old grid + extension To build the grid/clock as shown you will need: 1x LGC_Frame_v1.STL 1x LGC_Frame_Back_v1.STL 1x LGC_Front_Bezel_Thin_v1.STL 1x LGC_Elec_Case_v1.STL (including feet) 1x Arduino (Nano or Pro Mini, case fits both) 83x WS2812 LEDs (60 leds/m) 1x resistor (300-500 ohms, I'm using 330) 1x RTC module (DS3231) 2x push buttons (6mm x 6mm) 1 sheet of paper (120mm x 185mm, thin paper) 19x M3x6 screws Other requirements: - Working Arduino IDE including the used libraries - Basic knowledge of what you're doing. This thing is meant for people who played around a bit with a few WS2812 leds to gather some experience and who are now looking for an easy way to get a working grid. If you're totally new to this you might want to take a look at Adafruits Uberguide or other similar stuff (FastLED user groups). I will only show you how the grid is put together here - electronics are the same as in many of my other things. Buttons, RTC and Arduino/Power are connected the same, so you can use my instructions here: https://www.thingiverse.com/thing:3014572 and here (video included): https://www.thingiverse.com/thing:3095715
