Power supply
About the Power supply PCB
Power supply is an open source PCB design by shengwen-tw, published on GitHub under the MIT license. It is a 2-layer board measuring 66 × 38.7 mm, with 20 components from 18 distinct parts.
Other key parts include the MCS34063A. By type, the board carries 7 resistors, 4 capacitors, 2 diodes, 2 inductors, 1 IC and 1 connector.
It belongs with the displays & leds and power & battery designs in this gallery.
From the project
IN-14 Russian nixie tube clock
A Russian IN-14 Nixie tube clock which support time display, alram and mp3 playing function
You must install the following arduino libraries before compiling the firmware (find the zip in firmware directory)
DFPlayer driver (a modified version of AltSoftwareSerial) RTC and Time library
The hardware was designed under Kicad 4, any previous version may not work properly.
