Touch light music

During the holidays, he invented and made a sensory light-musical toy for his daughter. She is 8 years old and it’s time not only to listen to music, but also to decorate it. With the help of 5 kopek coins on a plastic box (the coins are sensors) when touched, the corresponding color LED 5-watt lamp lights up.

The upper sensor of each channel switches the modes:
1.Usual
2. Smooth
3. Stroboscopic
4.Automatic.

Very fast, with such a straightforward homemade, the daughter showed me how she developed a sense of rhythm. The index finger controlled the channel with red, the middle channel with green, the nameless channel with yellow, and the little finger controlled the channel with blue. It turned out very cool and colorful, but you need finger training ....

Ivan_Pokhmelev,
And bridges that, only for thyristors? In my opinion they are universal, independent and can serve for any purpose where necessary. You are probably interested in what part of the circuit they are?

The outputs operate on a composite transistor and are controlled directly from the circuit.

That is, low-voltage lamps, not 230 V?
If there are no thyristors, then why 4 diode bridges?

Ivan_Pokhmelev,
Well yes, I have a holiday all my life. And the modes are very simple: Normal - when you hold your finger on the sensor, the full brightness of the lamp is on the corresponding output, and when you release it, it goes out. Smooth - when you touch, the brightness increases from minimum to maximum within half a second, but if the finger is removed from the sensor earlier, the lamp will turn off, and if it remains, it will light up at maximum. Stroboscopic is a strobe effect, it works while the finger is on the sensor, and the frequency of blue is fast, yellow is slightly slower, green is even slower, red is the slowest. Each channel has its own independent generator and is tuned for the best effect.Automatic - the channels work themselves, without human intervention, like a Christmas tree garland with a smooth change in brightness.

Korolev,
There is no isolation, the circuit operates from a pulse B.P. on 24v. / 2A

Ivan_Pokhmelev,
It’s true about sources, but triacs and transformers are not there. The outputs operate on a composite transistor and are controlled directly from the circuit.

Korolev,
Yes, diode bridges KTs 402, I used them for their intended purpose and as mechanical holders for electrolytes ...

Korolev, power supply of the low-voltage part, apparently, through the Chinese IIP (in the upper right corner of the "power" block), and communication with triac units through transformers on ferrite rings.

The network (220V) wire from the "Pilot" to the structure is visible in the photo, diode bridges of the KTs type too, I will not undertake to determine the supply voltage
the corresponding color LED 5-watt lamp
, and how is the junction organized? scratch

In the holidays, I came up with and made a touch light musical toy
Let me doubt the timing. )))

The upper sensor of each channel switches the modes:
1.Usual
2. Smooth
3. Stroboscopic
4.Automatic.
What are these modes? The names do not say exactly about anything. ((

Razrabotchik,
What a heap of documentation, what bag of money, what are you talking about? Here, sipping seagulls in 10 minutes, a piece of PCB, aluminum tape, wiring and a resistor.




There is nothing to do. And if I needed it, so there is dynamics, and warm tube sound all that the soul desires ...

The circuit on the microcontroller works like a normal trigger, there is no pattern and dynamics, and mine is assembled on bricks and can change the modes and intensity of the glow.

ino53,
Why is it so loaded with takes.

feonor12,
For branded manufacturers, you can try to connect a bunch of people to the project with a heap of documentation and a bag of grandmas.

And what is the difference between 1 and 4 photos, 2 and 5, 3 and 6 among themselves? One and the same, repetitions ...

Try microcontrollers. Such a toy can be assembled on which thread Attiny 13, here is an example of a touch switch circuit for LEDs.



And then this is some kind of terrible dream of a ham. No, I believe that the circuit is working, but the last time I saw such a number of microcircuits in one device was in the TCO laboratory (technical facilities and equipment), they were soldered there from the decommissioned equipment ...
