Maybe you were the most insisting one but many others went meh...

:D I was. It is therefore nice to see that that one survived and can still be bought. But to rephrase the question: can the power supplies as used in the DCB1 also be used in this design with your permission ?

While we are at it: do you allow the use of your shunt supplies as used in the Mesmerize/DCB1 for this circuit ?

Kean is a fine young DIYer with originality and ethos. So he already wrote to me asking and I replied to him that he can adopt those supplies on my permission.

That is nice to hear. I just thought it would make life much simpler if we had the original Eagle files of Mezmerize and redesign the Kuartlotron on it or am I asking too much now ?

Salas 1st September 2015 11:31 PM

Original Mez is donated to the DIYA store for some years now. So I would not bcs not elegant to do so. Kean said he will have to rearrange positions of relays anyway.

Here is the shunt so far. Flat LEDs make for a less quirky, more compact layout. I'm trying to make it small so there is room for dual mono, but I'm not sure that can happen.

Make the LED pads dual purpose to suit both through hole and smd.

DC coupled?

Dual mono power, IE separate regulators for left and right. It might be possible if I move the pot quite a ways over, but that would deviate from the original board significantly. Then again, the exact positioning of the POT on the original board is unspecified, so I can't really put it in the right place anyways.

What size SMD?

Standard LEDs - SMD | Mouser

0805 is easy to solder. 0603 is hard for many.
