As its name tells, this is a resized and an easier to make/print version of ledclock project, powered by WLED.
There are TWO resized dimensions available:
- 52x92mm digits version : see folder
- 40x66mm digits version : see folder
Keep in mind that dimensions mentioned above represents only the height of the PCB digits. The base is not included. Height of the base is the same.
This fork is intended just to share the Gerbers and 3D files I used for this remix. If you need more detailed informations, please read descriptions and assembly guide from the original repository. imeszaros did an oustanding job in providing all the explanations required.
- all PCBs are under 100mm height so you can order them for like $5 + shipping from PCBWay.com . You can also order them directly from my PCBWay profile you can download the gerber files and send them to your manufacturer.
- 3D printed parts can be printed on smaller printers because the base is split in half (you have to assemble it with some M3 screws and nuts). I printed my parts on an Ender3 V2, so I guess anyone can print them.
- 3D printed parts can be printed without supports. Please check 3mf folder to see orientation if you can't figure it out.
- controller board, led 7segments and dots now uses only 0805 SMD components for easier soldering. I don't have a reflow hot-plate so I made the assembly by hand.
- controller board now uses an ESP32 D1 Mini link for reference for more convenience. By using an embedded ESP32 you will have to overcomplicate the board. Another reason for using a dedicated ESP32 D1 Mini is because some of the components required in the original design are impossible to solder by hand (CP2102). I f you want, you can use the original controller board design, is fully compatible with LedClock-Resized.
Firmware is provided by the awesome work of imeszaros. Just connect the ESP32 Mini onto the computer (be sure you have drivers installed for your board USB-TTL chip) and use this tool for initial flash. Then plug the ESP32 board it into the main controller board.
Assembly of this project is pretty straightforward:
- order the PCBs and solder them
- print the 3D required parts and assemble them (use 4 x M3x20mm screws and nuts to join the base of the 52x92mm version)
- flash the firmware on the ESP32 Mini and then connect it to the controller board.
- join the PCBs with the 3D printed parts
- provide 5V 2A power supply with 2.5mm x 5.85mm barrel jack connector.
- make your settings in the WLED APP. Use this guide if you're not familiarized with WLED App.
