Worth a try for sure. :)

The Arduino site advises a voltage between 7,5 and 12 volt. It would probably work fine, but when using digital logic they will not guarantee that it outputs 5v. It could be a bit lower. I think that all you need to do to mod the LCDPS for higher voltages is using another potentiometer.


Thanks, I sure will!

Good idea, you are the one with the powers to move it. The only question is where to put it?

Good news, I have two S/PDIF sources connected to my Twisted Pear 4 channel input board and get lock on each one when selected with the Arduino control. Corpius's code rocks, all four inputs work. (I physically moved my two coax inputs to all input positions to test).

Thank you Corpius!

While powered off, I checked continuity between pins 3 and 4 of the BIII DAC boards external I/O header and my star GND, and found GND is GND. The Arduino I2C GND is still connected to pin 3 of the I/O header with no problems (no hums or strange Arduino behaviour) so I'll just leave it there.

I installed my TP LCBPS and have 12 volts B+ going to my Arduino board. At this time I have Arduino power supply negative direct to the power supply.

Still in proto mode, but nice to have it working. This means I can start on a case with hole cut for LCD screen. I may just leave it with the 4x20 screen. I've had enough issues to deal with....



A nice hi-res vinyl rip I made. Also want to thank glt of HiFiDuino who started the Arduino control.



My other labor of love. A heavy plinth Swiss made Lenco idler drive turntable with linear tracking air bearing tonearm. I have both vinyl and digital sources covered now!

I've used it. The flange is 29mm diameter, the knob itself is 25mm. 30mm is what I would use for the cut-out.

I hope I am not offending TP here. I figured it would be all right as they don't offer a shield for the Arduino UNO.

I added the Buffalo shield that Corpius designed and markets. His shield and the LCDextra board reduces the wiring needed between components. I elected to use headers and connectors to the IR receiver, LCD, encoder and DAC board/Sidecar relay. The wiring to the DAC is shown in last pic. I picked up an assortment of round PCB boards at Radio Shack to mount the IR and encoder to. They have round traces around the holes on one side of the board to allow soldering the leads.

I ordered a Pesante 3U from modushop today. I got the big one, 450mm x 400mm x 120mm tall. While it coud be squeezed into a tighter enclosure, it was going to take up a shelf anyway so why not allow some room around components.

Nice. With the Amenaro you would not need you Denon anymore to play DSD. You can rip all you SACD's and play them with your computer.

I have been busy with my WavIO today, but I had forgotten to buy some connectors for the ribbon cable i'm planning to use with it. So the project is on hold until next weekend.

Hi Ed,

If I had some I would definitely use them. If I order the connectors today I can pick them up Monday right after work.

Though it isn't finished, I took my DAC to a friends house where we had a small audio get together. This linked forum (Rockford Audio Society) is a sub forum at Clup Polk (Polk Audio). Anyone can view it but you must be a member of the group to post in it.

My DAC was well received. We played hard media through my modded Denon and SPDIF via coax from an older Squeezebox II. The two comments. I love it when other folks reaffirm what I think about the DAC's SQ.

"I'll tell ya what. If God wanted to create a DAC then he had Rich's in mind. I think the easiest way to describe it is just WOW! Once it gets to its final resting place it will be an amazing piece of gear. All the hard work that was put in has definitely paid off. That paired with A2's amp and we had some pretty good tunes flowing."

"Rich's DAC is a wonder! Never seen anything quite like it and I 've had my nose in some pretty interesting electronics over the years. Oh...and it does sound fantastic!"

They loved the remote control and HiFiDuino/Corpius code. One fellow brought a Squeezebox 2 with laptop. We found the remote for the Squeezebox is similar to the Apple remote code. When scrolling through song listings, it also changed my DAC's input. At first it was like what broke, it worked a minute ago....

Modushop sent me a progress report, off to anodizing! Should ship next week.
