CHANNEL 4 UNUMINUMPHONIA - PRINTED PLATE
Producer: AVT
Illuminophones are one of the most-liked, effective and popular electronic gadgets. Their undoubted advantage is the incredibly 'media' way of action and a few years ago they were the object of desire of almost every teenager.
Older (traditional) constructions were completely analog. The audio signal was subjected to filtration in the analog filter assembly, and then the circuits assigned to individual frequency ranges controlled colored light bulbs. The low tones usually corresponded to light of warm colors (red, orange), high - cold (blue).
Current availability and versatility of digital circuits allows replacing them with difficult analog filters. We present and encourage such a modern layout.
The device is especially recommended for all kinds of parties, clubs and discos
Selected parameters:
- control signal from the audio power amplifier output
- frequency filtration in a digital filter with STM32F103C8 microcontroller
- four channels
- full galvanic separation of filters from the control part of the bulbs
- executive elements - triacs
- a system of pre-glow and gentle switching of the filament light bulbs
- phase control
- 230Vac power supply
- printed circuit board and documentation included

The Curvimeter – or opisometer – is a device that measures the length of curved lines and helps to calculate the distance between the points on a map more precisely than a ruler or a compass.
The mechanism has a measuring wheel, a clock face, and a hand. When the wheel moves along the line on a map that you need to measure, the hand moves around the clock face marked with measuring units – centimeters, inches, etc. All you need to do in the end is to check the map scale and to multiply your data by the denominator in the scale.
