A bit of a back-story of how this project came to be.
Sub if you like what you see.
Some pictures of the project
Project Structure
The project consists of
- Firmware
- Hardware
- Mechanical
These are structured into their own files. I could have used submodules, but decided against it.
1. Firmware
Code for the coaster. This lives on the ESP32
Requirements
- ESP32 IDF version 5.4
- Target set to ESP32-H2
- Install managed components
Required Managed Components
- lvgl
- espressif esp lvgl port
2. Hardware
Schematic
PDF schematic included for your viewing pleasure. File PCB_Coaster_v0.2_Schematic.pdf
PCBs
All the gerber files you'd need to send to a fab house. File PCB coaster v0.2.zip
BOM
Bill of materials file coaster-BOM-v0.2.csv
Kicad
All the files you'd need to expand and work on this further. If you'd like.
3. Mechanical
Diffuser
PCB Coaster diffuser.step
You can print this part with clear ABS fillament for best results.
Screen Holder
PCB Coaster screen holder.step
I printed this part with an SLA printer, it can probably do ok with a filament printer too
Spacers
PCB Coaster spacer.step
These print best on SLA. Filament printer will not achieve flat tops, though it might work. Best printed with SLA.
Screen protector
I used a Cricut machine and a thin accental plastic to cut out the screen protector. Ideally, this would be made of tempered glass. (maybe one day)
If you take it further
Let me know if you ever make one of these, I'd love to see it. Seriously, that'd be exciting and inspiring to keep making my projects open source!
And if you got this far...
Consider signing up for my mailing list. As I run into problems when making these projects, I fire off an email with a small write up explaing the problem and the solution I found. Here is the link https://landing.stuckatprototype.com/exclusive
Stay fun, StuckAtPrototype
