In order to test the electrical resistance of insulators, it is necessary to have a voltage source. The required output voltage depends on the type of materials tested. In this case, it is a source of adjustable output voltage in the range of 50V to 2kV sine wave with a frequency of 50Hz. The power…
The design of a light source with a DMX interface, consisting of RGB LEDs panel, and thus able to illuminate objects with light of almost any color. Over 60 super-bright LEDs with up to 100,000 mcd luminosity were used in its construction. The device fits the KM-95 enclosure, which has a handle for mounting it…
DMX interface. These were mainly receivers and transmitters, as well as devices enabling the development of DMX networks. When running prototypes or large installations, you will definitely need a DMX scanner that can provide invaluable services. Recommendations: the scanner will be useful to people dealing with technical equipment on stage, technical setting of events, etc.…
The controller allows convenient control of the intensity of lighting made of bulbs. It is not suitable for use with typical energy-saving fluorescent lamps and LEDs, unless they are adapted to work with typical dimmers. There are many similar solutions and probably every electronics engineer has performed a “dimmer” at least once, but this device…
Digital PIC18F4455 multimeter is nowadays the most used measuring instrument for electrotechnical measurements. For users, the advent of digital multimeters meant above all reliability and instrument for measuring all common electrical parameters. Users’ claims However, this device is constantly growing and with the massive expansion of computer technology begins to be a new requirement to…
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…
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…
