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 open source has a complete host computer, slave computer and schematic diagram, as well as a detailed design paper.
This work designs a smart water cup holder that can detect the use status of the water cup and remind users to drink water in time. By connecting to the Alibaba Cloud platform, automatic clock calibration is achieved. You can also set parameters for the water cup holder on the cloud terminal. The main work of this project is to design a beautiful interface that is pleasing to the eye. The other is to connect to Alibaba Cloud to realize cloud sharing and intelligent connection.
A 100W fast-charging mobile power supply based on the IP5389 chip solution, equipped with an OLED display that can display battery power and temperature.
Pocket calculator style general purpose programmable device (computer) ideal for learning programming and improving building/soldering skills.
All files are open source, including software, hardware and 3D printing shells, and how to make and assemble them are described in detail, especially the EQ equalization filter test and frequency response test are explained in detail. The main control uses RP2040 + TI 24-bit asynchronous stereo audio codec PCM3060 with 96/192kHz sampling rate.
This board is based on the ST-ONE main control chip and uses the M0+ core
This time it’s an e-book based on the Raspberry Pi.
Open Book is an open hardware device for reading books in all languages of the world. It includes a large screen and navigation buttons, as well as audio options for accessibility and ports to expand its functionality. Its fine screen printing aims to demystify Open Book's own design, breaking down for curious readers how the book works and how they can create one for themselves.
snapVCC is a highly portable and convenient power supply for your electronics projects. It's designed to fit a 9V battery and provide you with 3.3V or 5V power wherever you need it. What can you do with snapVCC? Many circuits require a regulated 3.3 or 5 volt power supply. 9V batteries are an easily available power option. A common method of using a 9V battery to power a circuit is to use a linear regulator IC circuit to step down the voltage.
The Ant2 is a tiny USB-C lithium polymer charger that measures just 16 x 9mm, just larger than the USB Type-C connector itself. It is the smallest charger in its class. Ant2 can be used to add USB-C power and battery charging support to space-constrained prototypes and projects. The small size also makes it easier to retrofit USB-C power into your old projects.
PowerEver is a tiny electronic board that keeps your commercial power bank running uninterrupted while minimizing self-leakage current. It is user-adjustable and compatible with almost all power banks on the market. This means your power bank will never be short of power bank for your electronics.
Data Fitness Connector (DFC) A data broadcaster is a device that allows Peloton bikes to communicate with fitness watches, head units, and apps, a feature not available on stock Peloton bikes. It reads power and cadence data in real time via a cable connected to the bike and broadcasts them wirelessly to nearby devices, including those built around non-Peloton platforms like Zwift and Garmin (see which products are supported). This allows you to enjoy the built-in features of your bike while taking advantage of features and services that rely on third-party platforms.
The SOCORAD32, also known as the ESP32 Software Controlled Radio, is a professional grade hackable radio for amateur radio exploration, voice and data communications using simple AT commands. Just add a speaker and batteries and you've got a fully functional walkie-talkie. With a dedicated Push-to-Talk (PTT) button onboard, SOCORAD32 works right out of the box without touching a line of code!
ShaRPiKeebo is probably the smallest Linux computer you can find with a physical QWERTY keyboard. Measuring just 6 x 11 x 1.5 cm, it's powered by a Raspberry Pi (RPi) Zero W or 2W and features a 400x240 pixel, low-power, daylight-readable, black-and-white SHARP memory display and long-range wireless transceiver.
