RGB Led cube circuit is basically a real 3D display. Its resolution is determined by the number of LEDs. Greater resolution offers more faithful effects, but the demands on RGB LEDs and controls increase with the cube. So it is advisable to choose the right compromise, between difficulty and resolution. Here is the size of…
Switch Mode DC DC Adjustable Power Supply The TL494 system is the heart of the stabilizer. Elements C13-1.5NF, R14-10K set the frequency of the internal generator work to about 77 kHz. Comparator first, along with elements R7, R8, R9, R15, R16 and C14 are the output voltage stabilization circuit, which the value is regulated by…
ATmega328, BLDC Motor, Gyroscope, accelerometer, inverse pendulum, I2C bus, Martinez V3, controller, modeling simulation, Matlab, Simulink, MPU6050 This work deals with the construction of two-wheeled mobile robot and subsequent creation drivers and controls for its sensors, motors and controller design. Management works on Arduino platform with ATmega328 processor. In the first place, the research is…
There are a lot of different soldering stations on the Internet, but everyone has their own characteristics. Some are difficult for beginners, others work with rare soldering irons, some are not finished, etc. We focused on simplicity, low cost and functionality, so that every beginner radio amateur could assemble such a soldering station. A regular…
Phone Ring Amplifier Circuit People with hearing problems do not hear a phone call or intercom. Often the reason is the low volume of the bell built into the device. This project can eliminate this problem. This project is not an amplifier in the literal sense. Rather, it can be called a sound comparator, which…
Smps circuit controlled by TMS320F28062 IR4427 Gate driver. Designed with pfc circuit L6562 The design of printed circuit boards and the creation of electrical schemes is realized through Eagle cad. Due to the design of the resulting device, the inlet filter is together with an active rectifier placed on a separate printed circuit board. On…
This block is used to reduce and stabilize the voltage produced by the PFC block. The output voltage of this block is controlled by the control signal. Since the output voltage is higher than the safe touch (according to the CSN standard), it is possible to use the lower switch at the lowering drive. UCC28C43…
The reproducibility of DC-CDI in most implementers faces the difficulty and little experience of transformer winding. Therefore, this design, based on DC-CDI is used to transform the voltage using a PC power transformer EI-33. So there is no need to wind up any transformer. The necessary EI-33 transformer can be obtained from older types of…
This wiring is a module that makes it easy and easy to distinguish good operational amplifiers from defective ones. The op amp tester is designed to test simple, double and quadruple operational amplifiers. The wiring diagram of the opamp tester is shown in the schematic diagram. There are components in the tester that, together with…
The project deals with the construction of a universal display panel with 6 8 segment display tubes (numitrons) IV-6 of Russian production. The panel is also supplemented with a control unit with Atmega32 processor, where software for realization of clock is implemented. The operation of the device is the same as with the classic digital…
