Retro 7 Segment Clock SE (Small Edition)

thingiverse

This is a smaller edition, or "SE," of my Retro 7 Segment Clock, which can be found at https://www.thingiverse.com/thing:3014572. There's also another redesign, sized like this one but horizontally and with dots, available here: https://www.thingiverse.com/thing:4190016. <b>Update:</b> I've created a complete Build Walkthrough of this thing, which can be found on YouTube at https://www.youtube.com/watch?v=BRm6vKyph1Q. Note that the wire colors in the video don't match those shown in the pictures here, but there's a schematic at the bottom that represents what you'll see in the video. -- <h3>29.09.2019 - Update to v5</h3> Version 5 is now the same code base for all my 7 segment clocks available on this platform. You can modify configuration settings like display digits (4/6), brightness, and more by using the variables at the top of the sketch. There's no need to dig into the code anymore - just tested and verified on SE, TE, RE, RE/XT, and XL/XT. Of course, you'll still need to download the appropriate sketch due to predefined LED arrays. Other features include: - Removed periodic palette cycling I'm not sure if anyone ever used it, but I think this should be tied to a specific time to swap colors every hour or so. I couldn't care less, so I removed it. And removing is a great feature, isn't it? - Many, many cleanups The setup routine and more have been changed quite a lot. Added some comments here and there. Brightness is now stored within an array (min/med/max) and EEPROM reading/setting has been improved. Memory usage has been reduced, especially when setting dbg=false. - Improved LDR support There are new variables on top of the sketch that allow you to adjust your LDR readout more easily. Additionally, you can define upper/lower limits to turn it dark/bright exactly when you like. - Greatly improved color handling Some palettes got minor changes. All in all, they're close to the old ones but I tried to get rid of some color flickering because of non-ideal color combinations at start/end of palettes. Also, color flickering/steps on low brightness settings have been greatly improved. Added some default color corrections/color temperature settings (great improvement on blue tones using ws2812b). Added some palettes using "HTMLColorCodes," which should make it easy to create own gradients without caring about R/G/B values. - Some kind of debug interface Using the serial console and having dbg=true, you can use your number pad to send buttons and/or change different variables. This makes creating own palettes and especially testing much more comfortable :D Power limit is set to 750mA on all of them and one of the first parameters inside the sketch. Adjust this according to the model you're using and how much your wiring/power supply can handle. -- This one uses only 2 LED strips (33 LEDs each) so there's not a lot to solder. The biggest part is 118mm x 141mm, so this can be printed on way more printers than the big version. There are now two LEDs per segment instead of three. There won't be much documentation as it's basically the same thing - just a bit smaller. So if something is unclear, have a look at the main things' documentation :). How to use/button usage and so on: Read the original thing's documentation. Finished clock dimensions: Width: 141mm (5.6") Height: 236mm (9.3") Depth: 30mm (1.2") (not including feet)
