It acts like four in one box, with the exception that it can be powered from a wide range of voltages, regardless of polarity, as well as AC.

I've been itching to make one of these. Is there a timeline for these to be available?
So Robert, I could theoretically use one 12v or 18v output from my power brick and use this to daisy chain 9v isolated to four more pedals? If that's the case, it would seem like a game changer. It would add value to all those cheap isolated (not really) power supplies on Amazon.
Those expensive isolated power bricks are overkill. Most pedals don't need isolated 9v, but it's likely that at least a couple of them do. Not a great justification for spending $200 on a power supply. This seems huge to me. Am I wrong?

Yep, that's correct. And it's not limited to 9V outputs, you can have four completely different output voltages if you want by selecting different regulators and DC/DC converters for each output.
The only thing missing from this iteration is that there's no option for negative voltage outputs.

This was the cheapest DC converter I found, but its 9v to 9v iso. Anxious to see your build list.
(The MXR Brick is going to be a real bargain now when this comes out. Its got two extra 18v outputs that could finally be used for something.) Keep the utility stuff coming. Love it.

So potentially several of these could be powered by a 5amp supply like this one? https://www.amazon.com/LeTaoXing-9V-Power-Supply-Transformer/dp/B08K2WJ31N/

Yep.
These are the DC/DC converters I'm using for the prototype:
84mA per channel:
or
250mA per channel:
Keep in mind part of the "gimmick" of this particular project is that is can accept a wide range of input voltages in either polarity, as well as AC.
If your only concern is multiple isolated outputs and you don't care about the "universal" input voltage we can put together a better suited project that is a bit more efficient in terms of power consumption.

Any isolated power supply where I don’t have to deal with mains voltage would be rad.
Yeah, my interest is in clean power for less than $20 per output. Something with 24v-9v input makes it adaptable with a lot of cheap commercial power supplies.

Also, with the amount of C2CE builds around here I'd bet I'm not the only person interested in a diy "Mr. Universe" type high draw >500mA 9v isolator even if it's just a single channel. As always, moar is moar when it comes to power supply needs.

Why thank you.
Judging from the sounds outside everyone decided to celebrate. I'm flattered.

Hmm, they're celebrating here too. Who knew you were that famous.

It’s awfully nice of them to televise it so you can see it.
