At the same time, the author has open sourced all design-related schematics, PCB, source code and other materials for reference by interested enthusiasts.
There is a risk of electric shock and fire with this project! Light bulbs are essential devices in our lives. Incandescent and fluorescent light bulbs are typical light bulbs for household lighting fixtures. For industrial and public purposes such as street lighting, large indoor lighting, sports field lighting and any outdoor activities, apart from these bulbs, HID (High Intensity Discharge) lamps are also widely used. Typical HID lamps used for this purpose are high pressure sodium, metal halide, and mercury lamps. The last one has been banned in 2021 by the Minamata Convention on Mercury. Fixtures with incandescent and fluorescent bulbs, long used for home lighting, became obsolete within 10 years of the widespread adoption of LED lights, and currently offer only replacement bulbs. Low-wattage HID lamps are also gradually being replaced by LED lamps. High-wattage HID lamps still dominate the mainstream of large-scale lighting because the advantages of LED lamps at this level are smaller. Like many LED geeks, I built an LED fixture because it was rare, but when it became commonplace it stopped being fun. On the other hand, my nostalgia for the disappearance of glass tubes from our lives increased and I started collecting HID lamps as a light bulb geek. However, having only light bulbs makes no sense. In order to light a HID lamp, a lamp ballast rated for each bulb is required. Therefore, I designed and built an electronic HID ballast that can light a variety of HID lamps.
The portable soldering iron launched by PINE64 in the early days was based on the GD32 design. This time it was upgraded to the second generation product, which was changed to the domestically produced BL706. Its feature is that it supports low-power Bluetooth. The Bluetooth OTA upgrade function will be added to IronOS later. IronOS supports a variety of portable DC, QC, and PD powered soldering irons, and supports all standard functions of smart soldering irons.
The hardware design adopts upper and lower layer design. The upper layer is the control circuit and the lower layer is the dual receiving circuit. The interface design is based on LVGL.
The keyboard uses a modular design. The multi-functional scene interaction module on the left can be replaced with various custom components. By default, a Dynamic component with an e-ink screen and FOC force feedback knob is used; the keyboard body uses a shift register method to implement the key scanning circuit; The module and keyboard body can be used alone, or they can communicate and call each other through the serial port protocol.
SimplePnP is designed to be reliable, accurate, affordable, and adaptable to a wide range of components. It's a great choice for electronics startups, inventors, researchers, and hacker spaces.
There are many I/O methods that simulate UART, SPI, and I2C protocols, but there are very few that simulate CAN protocols. The CANT introduced today is a CAN bus simulation implementation. The original project was demonstrated on the ST Micro Nucleo-H743ZI board. The author recently launched a C and Python package - canhack, which facilitates porting to various chips without CAN.
This board is a Swiss Army Knife for IoT security researchers, developers, and enthusiasts. The board can be used with different types of software, including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack-firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even Specific software requires writing your own software.
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.
The hardware is independently completed by the Raspberry Pi microcontroller RP2040, which costs 5 yuan a piece. Just close a trigger design baseboard designed by KiCAD. The software is created using VSCode + GCC + Cmake. It doesn’t matter if you don’t know how to use it. The firmware is upgraded using the U disk drag-and-drop method that comes with the Raspberry Pi chip.
Wigl can hear the notes of any instrument and respond with movements, lights and special dances! Wigl helps motivate children and adults to practice their instruments. By sequencing the notes, you can program special dance moves for your Wigl. This combination of right-brain creativity and left-brain logic makes it a unique robot for any home. How does WIG work? Wigl has a microphone, a microcontroller (brain) and some motors for movement. Wigl is always listening for notes, and through some complex math it can hear individual notes.
Uses infrared light sensing to determine changes in blood oxygen levels in the brain in real time. Use the device in less than ten minutes to learn how to directly change blood flow to your brain. Neurons do not store energy, so regional brain activity is closely related to changes in blood oxygenation, where healthy blood flow patterns are essential for high function and growth of the brain.
Reliable health monitoring has traditionally required us to tether ourselves to machines that record our vital signs around the clock. However, outside of clinical settings this is rarely practical. We developed HealthyPi v4 in part to address this challenge. Building on its predecessor, HealthyPi v4 is a fully open source standalone vital signs monitor with wireless and wearable capabilities.
The EEZ Bench Box 3 (BB3) represents a new class of modular test and measurement (T&M) equipment. It provides a complete open source hardware and software framework that bridges the gap between DIY hobbyist tools and professional desktop equipment and combines their best features. Inspired by the EEZ H24005 power supply, BB3 has attracted many enthusiasts with its extensive feature set, rich user interface, DIY friendliness and completely open source design. BB3 will initially feature modules that provide the same functionality as the H24005, but these modules will plug into a single device, providing improved modularity, greater capacity, more processing power, an easier-to-use interface and enhanced flexibility, all These are available in compact form factors.
Dreamweaver 4N is a four-note sequencer with potentiometers, allowing users to create their own unique music.
The Skull is a Capture the Flag (CTF) puzzle that invites you to explore the innards of the AVR architecture. It has multiple stages that may keep you busy for days or even weeks as you flex your brain muscles and apply them to her riddles. Unless, of course, your mind loses its grip on reality and you fall into a swirling void of madness with no anchor. In this case, it may take you longer. To keep your head above water, you need three things: the ability to read and understand Arduino code, a willingness to spend some time reading the ATtiny45 datasheet, and basic programming skills.
