Starfish: an open source project for motor control board using component pick-and-place of RP2040 and TMC2209

Starfish is a pick and place machine control board built on the Raspberry Pi RP2040 microcontroller and Trinamic TMC2209 motor driver. This control board has some similarities to a 3D printer control board, but it has some unique issues to solve—including controlling solenoids and communicating with vacuum sensors. All board information is open source, and detailed explanations are provided to help you copy successfully.

Raspberry Pi microcontroller 100Msps dual-channel oscilloscope software and hardware are fully open source, including detailed instructions

The current design solution uses an 8-bit ADC chip ADC08100 and a 100M bandwidth front-end analog circuit. In fact, if you want to play, you can improve the indicators and use AD9288 or the domestic alternative MXT2088. One chip has two channels and achieves a 250M sampling rate through rapid alternating sampling.

SpaceX Starlink user terminal modification

Author Lennert Wouters demonstrated how to execute arbitrary code on Starlink user terminals via a custom modchip injected with voltage faults, and notified Starlink of these vulnerabilities.
Although the details are open source, the author does not sell the finished product, nor does he provide details of the modified endpoint firmware and fault injection used in the attack.
The transformation is to use a Raspberry Pi microcontroller
