This reference design boosts a single-cell battery voltage to a 10W output using the MAX669 controller in the bootstrapped mode.
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.
This reference design provides design guidelines, data, and more for a 1kW server power supply using a phase-shifted full-bridge DC-DC converter.
Resonant LCC 90 W laptop power adapter based on L6599 and STP9NK50ZF
The indoor environment monitoring terminal can monitor the indoor environment (temperature, humidity, lighting and other parameters). The terminal is equipped with a liquid crystal display module; it can realize real-time display of environmental parameters and clocks. The terminal is equipped with an audible and visual alarm circuit, which can set a certain When the parameters exceed the limit value, an audible and visual alarm will be issued; the terminal is equipped with a Bluetooth function, and the mobile phone can communicate interactively with the terminal through Bluetooth. It can realize functions such as detection terminal system time upload, real-time parameter query, sound and light alarm switch control, scheduled upload switch control, and alarm threshold setting.

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.
This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.
