From the project
MSF Owl Clock
The board with the ferrite rod antenna and two TFT displays attached.
The above images are the boards as delivered from fabrication, not the end product. Namely: The edge / tool rails need to be cut off to leave only the owl-shaped board A ferrite rod antenna (and tuning capacitors) need to be attached, creating a branch on which the owl perches (yellow tie-wraps for talons) Two TFT displays need to be secured in place for the eyes A base / stand needs to be 3D printed, which will also hold a speaker and its cavity

MsfOwlClock: common questions
What microcontroller does the MsfOwlClock use?
The MsfOwlClock is built around the PIC32CX1025SG41100-I/E5X, from the PIC family.
How big is the MsfOwlClock PCB?
The MsfOwlClock measures 130.1 × 183.6 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the MsfOwlClock?
378 components, from 82 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the MsfOwlClock design files?
From the pete-restall/MsfOwlClock repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the MsfOwlClock design in my own project?
Yes, under the terms of its MIT license, which pete-restall chose for the repository.
Can I test firmware for the MsfOwlClock without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
