Light Activated Switch Circuit. Switches, including those reacting to changes in lighting, are still very popular and practically used by electronics or automation specialists. This time we propose to make a simple light-responsive switch system, but powered directly from 230 V AC. while the assembly diagram in Figure 2. The actuator that powers the light…
EMG Processing Arduino Focused on the design of active hand prosthesis. This work summarizes upper limb anatomy with focus on forearm. Subsequently, it deals with amputation techniques and indications for amputations. The part describing contemporary prostheses is important for the design of active forearm prosthesis, which is described in the third and fourth chapters. The…
The subject of this project is realization of CNC milling machine, designed for production of smaller machines light alloy and PCB components. This will be subject to selection of mechanical components and drive. The mechanical construction should not be too complex due to limited production means, however, a laser cutter is available and the possibility…
The Led Cube project was made of LED cube, one side consisted of eight LEDs, a total of 8 obsahuje = 512 LEDs. By multiplexing always the eight LEDs, any spatial “picture” can be made from luminous LEDs. The cube can be used for aesthetic purposes, presentations, games (eg 3D Snake), etc. A total of…
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…
