Atmega8 + PCB control indicator
"Almost" acoustics
No miracles, a VU indicator for the amplifier. Project from https://danyk.cz/avr_iv2_en.html. Changes in the schematic include power supply from the power amplifier through two series regulators, and input level adjustment on the PRs. My contribution is the plates making it a module for the front panel:
PCB in lay6 format.

As for me, it works a bit too "nervously", although it's a matter of taste as you like. :) [Read more]
It looks cool, but for me it's an excess of form over content - why push atmega for this purpose? Such an indicator can be implemented on the LM3916 and the Peak meter indicator can also be easily... [Read more]
I will say more, why use diodes, when you could put classic V-gauges. Probably "to be pulled out" cheaper than the new atmega now. BTW: Cleverly made front panels. [Read more]
Especially since this LM will be more expensive. Just use Padauk's uC or some new tinny series and LM will be more expensive. That's why I have a uC to use them. The new tiny costs ~ PLN 3,... [Read more]
The uC was the easiest to use electrically, and the module was supposed to match the aesthetic concept (preamplifier visible underneath, second power amplifier and tuner). Swing-out with such a large rectangular... [Read more]
It was a joke with the tilting one - of course they wouldn't fit in the housing. However, I would make flat rulers, not arched and one under the other or divergent, and windows in housings of the... [Read more]
Doing something like this in analog is a complete misunderstanding, not these times. Why complicate the design, increase the cost, limit the possibility of modifications? [Read more]
And I completely do not understand placing such trinkets in such a form in an amplifier. If it was calibrated and indicated the power output, I would understand. But without that, what's it for? Just... [Read more]
Whatever, whatever. You can scale (there are PRs), scale can also be applied, but why? It is supposed to blink, just like the VU-meter on the 2*20 LCD described on Elektroda or the Chinese rulers. The... [Read more]
For it to make sense. I don't like pointless trinkets in the equipment, for me it's just "wiocha". Personally, I'd prefer a plain/bare front-panel to such flashing trinkets, Just just for... [Read more]
If anyone likes looks... :lol: [Read more]
With all due respect, you're the lover of appearances here. You named your creation "Vehicle Indicator" (for the amplifier). And what is the boost indicator??? For it to be called a VU indicator,... [Read more]
To be exact, from SJP: meter: an instrument used to measure (e.g. voltage) indicator: a measuring instrument that indicates the state of something e.g. voltage indicator: an instrument for detecting... [Read more]
I don't confuse concepts. I know what a gauge is and what an indicator is. It is generally accepted that we expect the indicator to indicate the presence of something (some signal, switching on something),... [Read more]
E.g. fuel gauge. Instead of white graduation lines, I have gaps between the diodes :) https://obrazki.elektroda.pl/6099619600_1676035640_thumb.jpg There is indicative information about the value... [Read more]
Well, no. In their constructions, people can connect similar diode lines in different ways; e.g: - at the preamplifier input, right after the input selector (because they shine so much better); - on... [Read more]
Buddy Tytka, you're right, maybe I really took a big shortcut. Connection in the only correct way in my opinion (I don't use the tone control for the power amp), and the fact that the end of the... [Read more]
In general, when it comes to appearance, it's quite good, although there is no scale, although now thumbnails are in fashion ;) However, personally, I am not in favor of using processors where there... [Read more]
