gk is a small battery-powered handheld game console based on an STM32H757 microcontroller (600 MHz) and 128 MiB XSPI SDRAM.
The Speeduino project is a flexible, fully-featured engine management system (EMS aka ECU) based on the low-cost open-source Arduino platform. It provides the hardware, firmware, and software components that make up an engine management system, all under an open license. With over 1,000 installations, Speeduino has evolved into a product that meets the needs of the hobbyist and enthusiast community without the price tag of a traditional aftermarket ECU.
CANable 2.0 is a small, low-cost, open-source USB to CAN adapter. CANable enumerates as a virtual serial port on your computer and acts as a serial line to CAN bus interface. Using the alternative candleLight firmware, CANable enumerates as a native CAN interface on Linux. CANable 2.0 supports standard CAN and CAN-FD.
The CANable adapter is compatible with ARM-based embedded platforms such as Raspberry Pi, Raspberry Pi Zero, ODROID, BeagleBone, etc., making it ideal for integration into OEM products.
Cruelfox, a forum expert, has updated his article to share with you an experimental idea of a CNC experimental power supply. The power supply uses two domestic chips, with a 3,000-word detailed explanation. He briefly talked about the first experimental power supply he made, whose shell was an aluminum medicine box and whose knob was a toothpaste cap. He mainly talked about the ideas and principles of the current mini PCB pocket version.
WiCAN is a powerful CAN adapter based on ESP32-C3 that can be used for car hacking and general CAN bus development. It is available in two form factors: OBD-II and standard USB-CAN. The original firmware can interact directly with RealDash using Wi-Fi or BLE, which allows you to create custom dashboards with beautiful graphics. It is available for Android, iOS, and Windows 10. WiCAN connects to your existing Wi-Fi network and any device on that network, and it allows you to configure Wi-Fi and CAN settings through a built-in web interface. Both versions have a power saving mode that detects when the voltage drops below 13 V or other preset values. When this power saving mode is enabled, WiCAN is able to enter sleep mode, reducing the current consumption to less than 1 mA.
This is a fun electronic toy car that features power-ups! The author uses color sensors and magnetic switches to trigger fun tricks like acceleration, deceleration, and rotation. It draws a lot of inspiration from Mario Kart.
After a failed Kickstarter campaign, the author has now open-sourced the software, hardware, and mechanics.
Dimebots are a group of autonomous, independent micro-robots that are as small as a dime, making them among the smallest robots in the world.
This is a very simple open source scanning laser rangefinder. It uses triangulation. Its components cost less than $35 (excluding shipping). This lidar is very useful in robotics - for SLAM and navigation tasks.
