ReFil
About the ReFil PCB
ReFil is an open source PCB design by n0skill, published on GitHub. It is a 2-layer board measuring 50.6 × 30 mm, with 19 components from 13 distinct parts.
Other key parts include the 7805. By type, the board carries 5 connectors, 4 resistors, 3 diodes, 2 capacitors and 1 IC.
It belongs with the displays & leds and sensors designs in this gallery.
From the project
A machine that makes filament suitable for 3D printers out of normally unrecycled plastic parts such as HDPE from bottle caps, failed prints etc.
The board will be used to: 1) display the current temperature 2) drive the motor 3) drive the heating element
Once the temperature is known, the arduino uses BCD encoding to controll the CD4543BE 7 segment display driver, which displays the temperature.
It is using the 24V from the barrel jack and is toggled using a SRD-05VDC-SL-C relay from SONGLE industries.
