Schematic PCB

Changshu Polytechnic Water Lamp

Introduction: It mainly uses the multi-harmonic oscillation circuit of NE555 that can send out stable and regular signals as the signal benchmark to send signal pulses to the counting circuit. The mechanical language of the counter is converted into binary numbers, which are displayed by LED lights.

[Analog Circuit] Dormitory Magic Lamp Switch Dimming Circuit

Introduction: A low-end version of the magic lamp for dormitories, which is a USB lamp without a controller.

Schematic PCB

[Analog circuit] NE555 Ambilight RGB Lite version

Introduction: NE555 drives a simplified version of RGB. The waveform is somewhat different from the standard triangle wave.

Schematic PCB

[Analog circuit] NE555 steering gear tester circuit

Introduction: 50Hz is obtained by receiving power frequency radiation shaping, and the driving timing of the servo is formed through monostable state

Schematic PCB

"Simple" RGB light gradient using 555 chip

Introduction: The design uses 4 NE555s, 3 of which generate triangular wave signals that are output in sequence, and drive the LED with constant current through the transistor to make it gradually change. The other channel generates a PWM signal to control the LED brightness.

Schematic PCB

Relay + capacitor = T flip-flop, cascaded to form the NE555 clock of the asynchronous counter

Introduction: This project uses 8 relays and a capacitor to form a T flip-flop, which is then cascaded to form an asynchronous counter, and matched with a clock composed of NE555. Turn on the power and start clicking~

Schematic PCB

Geiger counter ILI9341TFT touch screen version

Introduction: A Geiger counter is an instrument used to detect and measure ionizing radiation. It is one of the most famous radiation detection instruments in the world because it can be used to detect ionizing radiation such as alpha particles, beta particles, and gamma rays, and is commonly used as a handheld radiation survey instrument.
