16. Marking a DCC function decoder (part 2) - Powering from DCC #dcc #modelrailroad #AtTiny85

Taking power from DCC track! follows on from https://youtu.be/f7LK-K4Hg_s In this episode we take the AtTiny85 based light flashing circuit from episode 15 and add the components required to power it from DCC track power, with a brief stop over powering from 12V DC this supply circuit will provide a regulated 5V DC from a DC or SC input of 7V or greater, meaning its also useful for DC layouts with a 16V AC auxiliary supply. we consider linear voltage regulators, touch on heat issues and then move on to rectification and smoothing of the DCC waveform to provide usable power including a low power stay alive for smoothing Thingiverse links to the Servo mount, without and with switch mountings https://www.thingiverse.com/thing:5403588 https://www.thingiverse.com/thing:6656341 Github repository with the episode code and the code for all the previous episodes https://github.com/aleopardstail/Frazzled/tree/main configuration links ESP32: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json ESP8266: http://arduino.esp8266.com/stable/package_esp8266com_index.json AtTiny85: https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json All Three: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json, http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json #arduino, #AtTiny85, #modelrailroad, #electronics, #howto
