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.
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.
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.
A Raspberry Pi board is used as the processor to process eight brain electrical signals in real time.
Although Geiger counters can be used to detect amounts of radiation, and with some tricks can also differentiate between the three types of radiation (alpha, beta, and gamma), their use is limited in identifying radioactive materials. For this purpose, gamma-ray spectrometers come in handy.
Maker Kits are a set of DIY open source templates for building things using IBM AI services in fun and easy ways. IBM TJBot is the first maker kit in the series. You can 3D print or laser cut the robot's body and then bring it to life using the resources provided by IBM! Additionally, you can unleash your creativity and create new recipes, using any of the available IBM AI services to bring TJBot to life! TJBot only works with Raspberry Pi.
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.
Pocket calculator style general purpose programmable device (computer) ideal for learning programming and improving building/soldering skills.
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.
The Raspberry Pi microcontroller itself does not have an Ethernet MAC, but it can be easily implemented through the programmable IO of the Raspberry Pi. The programmable PIO of the Raspberry Pi microcontroller that costs 5 yuan a piece is indeed a miracle, with IO below 250MHz. Control everything.
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.
The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture, utilizing the I2C bus to communicate between nodes
This article designs a vending machine based on the 80C51 microcontroller produced by INTEL.
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.
