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

Xenon lamp ballast

There is a risk of electric shock and fire with this project! Light bulbs are essential devices in our lives. Incandescent and fluorescent light bulbs are typical light bulbs for household lighting fixtures. For industrial and public purposes such as street lighting, large indoor lighting, sports field lighting and any outdoor activities, apart from these bulbs, HID (High Intensity Discharge) lamps are also widely used. Typical HID lamps used for this purpose are high pressure sodium, metal halide, and mercury lamps. The last one has been banned in 2021 by the Minamata Convention on Mercury. Fixtures with incandescent and fluorescent bulbs, long used for home lighting, became obsolete within 10 years of the widespread adoption of LED lights, and currently offer only replacement bulbs. Low-wattage HID lamps are also gradually being replaced by LED lamps. High-wattage HID lamps still dominate the mainstream of large-scale lighting because the advantages of LED lamps at this level are smaller. Like many LED geeks, I built an LED fixture because it was rare, but when it became commonplace it stopped being fun. On the other hand, my nostalgia for the disappearance of glass tubes from our lives increased and I started collecting HID lamps as a light bulb geek. However, having only light bulbs makes no sense. In order to light a HID lamp, a lamp ballast rated for each bulb is required. Therefore, I designed and built an electronic HID ballast that can light a variety of HID lamps.
