I first discovered Nixie clocks by accident while web surfing. After reading through several Instructables, creators web pages, and how Nixies work, I decided to make one from scratch as well. I did use other authors code snippets for certain elements of the clock. In my learning, I thought I would be able to create and etch my own circuit boards. After several trials and failures I deemed thi...
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...
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...
This is the code I use for the clock. Feel free to change it in each manner your want. ATTENTION: Dont use the POV Clock_old. I use it for backup purpose only. It wont work! The file POV Clock_new and POV_Clock_new_SSD1306 are working well and are fully tested. But i dont take any responability if something dont work like you want. For example: the optocoupler is tricky. Maybe you need to adjust t...
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...
This project is a relatively simple binary clock with an ATmega328PB microcontroller and 4x4 matrix of WS2812B RGB LEDs.
- RGB LEDs for different colorful display modes
- back up battery for time keeping
- two usb ports (one on either side) to choose from
- temperature and relative humidity measurement
- mini speaker for alarm feature
- light sensor for automatic brightness
- single joy...
