ESP12F based board with 4 relays, DHST and/or LM35 temperature sensor(s) for Local or remote temperature measurment. Sockets for clock based modules based on DS1307 or DS3221 clock chips for time tracking. Additional I2C ports provide expandability to I2C displays or other sensors.
Great platform for building web based switches and monitoring temperatures and other sensors and login with RTC chips...
Need to replace old broken defroster in my 240z but can not find any that are still working. Also needed to add switch to fog lights so figured willcombine the 2 plus add couple other functions to the controller and solve everything with single module to have following:
- defroster with auto shutoff 10 minutes
- fog switch dual filament one will be used as DRL.
auto shutoff with ignition swit...
Clock Module based on Ben Eater's project https://eater.net/8bit/clock, with some customizations based on Dawid Buchwald Clock Module's project https://github.com/dbuchwald/6502/tree/master/Schematics/Clock_module
Cool Nixie Tube Clock, design works out of the box. All parts (execpt for the tubes) can be ordered from LCSC, if you have any questions feel free to contact me via easyeda messages.
It is recommended to put the nixie tubes on special nixie tube pins, these can be found on ebay.
All design files are available from here:
A PCB design to power a BROSE FlipDotDisplay with a ESP32
This display is bought from the Ebay User "dampfbarkasse". You can find more details off this project on the homepage of this seller radow.org .
Most knowledge of this display at the moment is based on radow.org and the sellers arduino control pcb.
THIS LAYOUT IS NOT VERIFIED YET. But it will get tested, modified and verified in the next...
