Teacher ChaN’s latest power strip

The style of enameled wire is as usual, and the craftsmanship is still excellent. The power board designed this time is made of double panels, and a copper-laying design is applied. The insulation layer is laid first and then the copper. If the device on the front needs to be grounded, break the insulation layer and solder it to the copper.

Mini-DSO - a low-cost simple oscilloscope

A simple oscilloscope made of STC8A8K MCU. The microcontroller uses STC8A8K64S4A12 working at 27MHz. The display uses a 0.96 OLED with a resolution of 128x64. This oscilloscope project is easy to start and covers the necessary measurement functions. Supports normal mode, single mode, and automatic mode. It has trigger mode selection, such as level trigger, and comes with saved settings. Mini-DSO input is single-channel mode, and the second/division size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us, and the voltage acquisition range is 0 to 30V. The sampling rate can reach 250kHz@100us/div.

Interleaved CCM Totem Pole Bridgeless Power Factor Correction (PFC) Reference Design

Interleaved Continuous Conduction Mode (CCM) Totem Pole (TTPL) Bridgeless Power Factor Correction (PFC) using high-bandgap GaN devices is an attractive power topology due to its high power efficiency and reduced size. This design illustrates the use of a C2000™ MCU and LMG3410 GaN FET module to control this power stage. To improve efficiency, this design uses adaptive dead time and phase shedding methods. Nonlinear voltage compensators are designed to reduce overshoot and undershoot during transients. This design chooses a software phase locked loop (SPLL) based approach to accurately drive the totem pole bridge. The hardware and software used in this design help reduce your time to market.

Lazy self-care fish tank control system

The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
