Info regarding the 3D printer bonus task
As discussed the class, the optional problem for unit 4 is to build the circuit using the provided PCB and parts, and to design and manufacture a case which fits the PCB.
The KiCad project with the design, as well as some additional information can be downloaded below.
The design of the case is up to you — when I designed the circuit, I thought the green LEDs could be the eyes of a Halloween-decoration, for example.
Send me an STL file of your design. I will print out the nicest.
Further material
- KiCad project — select “unarchive project” in the file menu. It might ask about footprints for the BK-912 (coin cell holder) which are only in the cache. The default option will copy them to a local library. That should work. You can measure dimensions of the pcb via the measurement tool in the PCB editor. Note that there are two mounting holes which can be used to mount the PCB to your case. They are for M3 screws, but a 3d print might just have small pins which fit these holes.
- TinkerCAD
- OpenSCAD
- Cura (slicing software)
Information from iCREATE
iCREATE additionally provided this information:
3D Design of PCB
- To Design a case for a PCB we would recommend to look at:
PCB case designs on Thingiverse to browse: https://www.thingiverse.com/search?q=pcb&dwh=125e594fd8d60da - Next step would be to select a Thingiverse model that has the “Customizer” ability, where the model can easily be modified within Thingiverse and downloaded directly. Example: https://www.thingiverse.com/thing:3588987
- For full customizability, the students can use Tinkercad to design and can view the learning modules provided by Tinkercad on their website: https://www.tinkercad.com/learn.Two tutorials for TinkerCAD: Getting Started In Tinkercad, Tinkering with TinkerCAD
