Default parts placement

Wendell, hope this helps. 470r one stands soldier style.
Relay I used is OMRON Mouser 653-G6H-2-100DC12

Thanks for the quick reply! Looking on the underside of the board gives a correct perspective.

And the matched sk170 beside the relay?

Yes. Near relay. The whole Buffer part (the rest power supply) is after the VOut* seen on right of pic. So all to the left is the buffer, not much to it. The Vout* jumper (white stripe) must be applied in order for Buffer to power up. Otherwise it's just a nice shunt reg supply. There are two other jumpers that need to be done in the power supply as well.

Hi Just saw this!!! Sorry Korben69

Its very difficult to explain, but if you havnt already set up your dcb1 with optivol, you could try having a look at page 167 post 1665 There i have posted some pics of my build...the pics are not very good quality, but you can see how the two are connected together. If you cant quite work it out by looking at the pics, then pm me and i will try to explain

On a side note, I would highly recommend powering the optivol, with a Salas Shunt reg set to 5v...i tried quite a few combinations of power supplies for running the optivol and by far the best was removing the power supply section of the optivol board and running direct with 5v salas shunt reg, i did try the salas shunt reg set to 8v as a prereg, and then this went into the optivol 5v supply, but this did not sound as good. Pics to follow.

Alon

I think the photo that Tea Bag uses as an example is the prototype with no solder mask.

A couple of questions:

The "Blue" Hypnotize BOM specifies a 2x15 transformer while the 'original' Hypnotize-Mezmerize specifies a 2x12. What's different???

Can someone please summarize the pros and cons of the 12v relay vs the 5v relay??

Thanks,

Thank guys you for your answers

Malka07, I'll send you a PM for my built, your help will be great. Very nice result, I like the "Zen look" !
I use a Mezmerize board not Hypnotize. I'll try a GoldMinireg as PSU for the 5V.
Your pics show that you've wired the LDR Output(L/R) to the Hypno Input(L/R).
How should I proceed with the Pot on the Mezmerize PCB ?
Should I just ignore it ?

sandbasser, the LT7812 gets a little bit hot when using 5v relays : heatsink recommended.
My mistake, the tansformer is 2x15v. 2x12 is a typo. Some Selectronic RCore are oversized as mine, 2x15v gives about 19.5v at the output...

Salas, yes, bending the LT is the right solution. I'll give it a try.

Thanks,
The Blue is geared up towards heavy use so it will be certainly sinked, thus more Vin to Vout created by a higher Tx makes it regulate in more ample margin without caring for some extra dissipation. They will run it up to 1amp some, wait and see...

12V will create less dissipation on its feed components. 5V option is when you can't find 12V cheap or available at a time. Basically there was a sub GB for 5V ones back then so we catered for both. 12V is the natural choice.
