Electrical CAD and firmware
2. Open the project in your IDE. 3. Install the required libraries listed in the dependencies section of the code. 4. Select the correct board and port in your IDE. 5. Upload the code to your microcontroller.
- Inputs: The controller takes crisp inputs from the sensors (e.g., "distance to target" from GPS, "angle error" from IMU). - Fuzzification: These crisp values are converted into fuzzy values like "Close", "Medium", "Far" or "Small Error", "Large Error". - Inference: A set of rules (e.g., "IF distance is Far AND angle error is Large, THEN deploy control surface a LOT") is applied. -…

Telem: common questions
What microcontroller does the Telem use?
The Telem is built around the PC817, from the Raspberry Pi family.
How big is the Telem PCB?
The Telem measures 90 × 90 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Telem?
11 components, from 8 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 Telem design files?
From the lukokemba2/Comeback-CanSat 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 Telem design in my own project?
The repository has no license, so all rights stay with lukokemba2. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Telem without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
