Project by Jeremy Fryer-Biggs
Early on during the microfactory's development, one of the projects that got us excited was the idea of doing a custom shaped circuit board with a custom printed project enclosure. This particular one was inspired by valentine's day and is comprised of a circuit with a timing chip which causes our robot "heart" to beat at a life-like 72 beats per minute!
you will need the carbide engraving bit for milling the circuitboard
first we created a schematic in eagle of the basic heart blinking circuit and then laid out the board on a custom shape.
next we exported the .dxf file from eagle and used cambam to make the tool paths for routing .
Once we were happy with the file we put a blank circuit board on the machine and executed the program )
(watch a video of the circuit board milling)
next we soldered all of the components to the board
and you can see the finished board blinking
first we designed the enclosure using CAD software
then we used Slic3r to create an additive tool patch in g-code
next we turned on the nozzle and heating bed and let both get up to temperature. Once warm we ran the program
and the part printed layer by layer
(see a short montage video of the enclosure printing)
and voila a custom shaped circuit board with matching custom project enclosure!!
