It has powerful functions, modular design, strong portability, low power, and has a wide range of application fields and development prospects.
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?
Lite3DP is a micro 3D printer that uses high print quality, virtually silent MSLA technology. It is the first of its kind to be completely Arduino-based, is open source, and comes in an easy-to-assemble kit format. It is a simple machine designed for experimentation to provide an in-depth and complete understanding of its operation. It can be placed on almost any table or in any workshop. MSLA resin 3D printing technology can achieve stunning levels of detail and surface finishes that are far superior to what can be achieved with filament 3D printers – primarily by using screen-cured resins such as LCDs on Lite3DP. Although 3D printers with MSLA technology are already available at similar prices to filament printers, they are closed-source projects that eschew one of the most valuable features of modern 3D printing - accessibility.
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.
Using Raspberry Pi pico (rp2040) as logic analyzer and oscilloscope with sigrok
The most interesting part is the problem of energy collection without batteries. Currently, it provides energy collection by clicking buttons and solar energy collection. Ambiq Apollo3 for main control.
Pellicanus is an open source, RP2040-based INS/GNSS module that you can program using MicroPython, C or Rust. It allows you to add Vertical Reference Units (VRU), Attitude and Heading Reference Systems (AHRS), and INS/GNSS capabilities to a variety of platforms: cars, drones, autonomous vehicles, and anything else you need to track. We'll Pellicanus is designed as a 33x30 mm toothed module that can be easily integrated into your project. We also offer carrier boards with a variety of interfaces so you can evaluate the module and start development immediately.
The current demonstration is running on RP2040, using one of the M0 cores as the GPU.
ERASynth Micro is an open source signal generator with impressive features. Affordable for everyone including builders, hackers, students, amateur radio and SDR users. The ERASynth Micro is powered via the USB port and has an LCD interface for stand-alone use without the need for a computer or phone. It can generate low phase noise RF signals from 12.5 MHz to 6.4 GHz through a dual PLL architecture.
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.
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
Reflow Master Pro is designed to work in any oven - no algorithm adjustments required! That said, if you really want to tweak, you can switch from the classic Reflow Master algorithm to PID control and adjust your settings to your liking.
In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open.

Mico is a high-quality PDM to USB audio microphone based on the Raspberry Pi RP2040 chip. Most compact microphones available for embedded Linux systems such as the Raspberry Pi have high noise and low sensitivity. By pairing a high-quality PDM microphone with a standard USB audio output, Mico gives you an audio input platform that you can tailor to your needs. Mico is a great platform to learn and experiment with the RP2040 and digital audio. It can be used as a universal USB microphone for a Raspberry Pi, desktop or laptop computer. Mico can also be used as a high-quality USB audio input for embedded machine learning applications. Additionally, because TinyML supports RP2040, Mico can be used as a standalone edge computing audio device.
This time it’s an e-book based on the Raspberry Pi.
PlainDAQ is a simple, useful tool that adds basic precision analog functionality to your Raspberry Pi Pico board. It features a precision, low noise, low drift 12-bit 500k sps/s ADC. To match the ADC and maintain its noise and accuracy, all analog inputs are buffered and the ADC is driven by a high speed/low noise fully differential amplifier. It also has a 10-bit DAC that helps create analog outputs and waveforms.
Neurostimulation involves the application of short electrical pulses to the surface of the skin to stimulate underlying nerves and muscles. In recent decades, neurostimulation has been used as part of functional electrical stimulation (FES) therapy to help restore movement to muscles in paralyzed limbs in stroke patients and people with spinal cord injuries. While conducting research in areas such as pain relief and sensory feedback, scientists also use neurostimulation to study the effects of electrical current on neurons. Historically, the delivery of neurostimulation has required the purchase of expensive research-grade equipment or costly, time-consuming custom hardware constructs. NeuroStimDuino provides an open source alternative in the form of an Arduino shield.
