Schematic PCB

Using Raspberry Pi Pico, a miniature Mars probe with an arm (schematic, PCB, 3D printing, source code, etc.)

Schematic PCB

Open source plankton monitoring and analysis equipment PlanktoScope

Plankton help remediate 30-50% of the world's carbon dioxide and provide the foundation for the global food chain, making up the world's largest daily movement of biomass as it travels across the ocean. The shapes, colors, and movements of these billions of creatures are as vast as the oceans that sustain them. Understanding plankton is crucial to understanding the world around us and our impact on it.

One obstacle to this type of research is the sheer size of the area to be explored, as well as limited resources for research fleets and specialized equipment. By developing a method to scale up high-quality visual exploration and documentation, we can greatly increase our understanding of the complex web of life around us, and how we in turn influence it.

Schematic PCB

Self-soldering PCB board design that supports reflow soldering (including PCB, schematic diagram, source code, etc.)

After the user manually solders a PCB board, this board becomes the reflow controller, and then this board can be used to control other boards for reflow soldering, because this board has been specially designed to open a heating layer.

Schematic PCB

USB portable programmable instrument (multifunctional USB power supply)

The core idea of ​​USB portable programmable instruments is to provide electronic engineers and enthusiasts with a series of low-cost, portable, network-enabled, programmable, and open source practical tools. The multifunctional USB power supply is the first of its kind and is expected to complement traditional adjustable regulated power supplies.

Schematic PCB

Desktop pen holder and calendar made with raspberry pi pico

In theory, it could connect to Google Calendar and show today's events while still being ongoing. Also on the list of features to be implemented is a switch or sensor that changes mode when the pen is removed, and buttons or touch controls for the user interface.
