With just a Raspberry Pi Pico, an analog switch and an op amp, you can build a powerful SDR receiver covering the LW, MW and SW bands. Capable of receiving signals from halfway around the world.
This year, Supercon badges become analog badges! (Or at least pretend to be pretty convincing.) Taking inspiration from the fluorescent oscilloscopes of the past, the 2023 Vectorscope badge is part analog audio playground, part art project, and all about prototyping. Who doesn't love the warm glow and lovely green fluorescence of an old Tektronix tube scope?
This is a simple USB sniffer based on the Raspberry Pi RP2040. It supports low speed and full speed modes. The firmware presents itself as a virtual COM port (VCP), so no additional software is required and it is compatible with all operating systems.
Flirting with jumper caps is a common practice on most boards, but not this board, which is designed to replace all those wires with an analog switch matrix. All one has to do is plug in the device and make a virtual connection on the accompanying GUI. There are also many built-in functions such as DAC and ADC, and the circuit can be switched under the prototype as needed. It also has some LEDs embedded in the breadboard area that light up and provide visual cues that they are connected to each other.
A small add-on board for the Raspberry Pi that I have designed specifically to solve the constant problem of shifting levels on sensors
Pocket calculator style general purpose programmable device (computer) ideal for learning programming and improving building/soldering skills.
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture, utilizing the I2C bus to communicate between nodes
The Raspberry Pi microcontroller 24-channel 100Msps logic analyzer has been upgraded to support 120 channels.
Daisy chaining of five devices is supported, allowing capture of 120 channels. Includes performance improvements and visibility improvements to the rendering engine, more samples in the screen, automatic selection of capture modes, editing capabilities, and more. The playability is getting higher and higher.
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.
The current demonstration is running on RP2040, using one of the M0 cores as the GPU.
This is a mature development board combined with a magnetic rotary encoder, which uses a Raspberry Pi RP2040 microcontroller with a base resolution of 36, expandable to 36,000 steps per revolution.
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.
