Retro 7 Segment Clock SE (Small Edition)

thingiverse

This is a smaller edition (hence "SE") of my Retro 7 Segment Clock: https://www.thingiverse.com/thing:3014572 And there's another redesign. Sized like this one but horizontally and with dots: https://www.thingiverse.com/thing:4190016 <b>Update:</b> Made a complete Build Walkthrough of this thing: https://www.youtube.com/watch?v=BRm6vKyph1Q Wire colors in the video do not match the ones in the pictures here. But there's a schematic at the bottom which represents what can be seen in the video. -- <h3>29.09.2019 - Update to v5</h3> v5 is now the same code base for all my 7 segment clocks here. Configuration like 4/6 digits (SE doesn't support more than 4 digits), brightness and so on can all be modified by using the variables on top, there shouldn't be the need to dive down into the code anymore. (Tested and verified on SE, TE, RE, RE/XT and XL/XT). Of course you will still need to download the appropiate sketch because of the predefined led arrays. Other features: - Removed(!) periodic palette cycling I don't know if anyone used it at all. But I think this should be tied to a certain time to swap colors each hour or so. I couldn't care less so I removed it. And removing is a great feature, isn't it? - Many, many cleanups Setup routine and so on 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's some new variables on top of the sketch which 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 some 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 is using 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's 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 things documentation. Finished clock dimensions: Width: 141mm (5.6") Height: 236mm (9.3") Depth: 30mm (1.2") (not including feet)
