Long radio silence, I know. I've been very busy with all kind of different things, but also a little bit with the controller. Most of the PCB designing have been done, but I need to do some (more) breadboard prototyping in order to know all works like I want it to. I have been struggling a with the remote learning function when working with all the different RC protocols. I'm still not fully satisfied, but I'll get there.
I included a temperature sensor to the PCB, but I don't know if I want to keep it there. Perhaps it's best to have a outbreak with the sensor.
The LT1086 low dropout voltage regulator and a resettable fuse have also been included into the design .

I will post some more details and some pics soon when I find some more time to work on it.

Looking forward to it

Just thought of something that could be an idea too. A second Voltage regulator circuit for more power hungry display`s.

I think that you are referring to the vfd display, right? how much current does yours draw?

Up to 350mA, typical 275mA.

I dont remember where I found the extended data sheet where it stated up to 350mA though.

The LT1086 is rated 1.5A which should be enough.

I`ll have a closer look at the spec sheet. I am not sure if the LT1086 can power more than the uno`s 7805 wich in some cases fall short due to temp. Should not be a problem though, just thought an additional reg could make it even more rugged

Almost there. I added a DIP switch to allow manual control over stereo/dual mono and volume control on/off. I have to do a few more tests (wish I had some more spare time), but I will order the first PCBs for the prototype this week for sure.

Here are some pics as promised. Also a pic from the RTC function that shows the actual time and date when stand-by mode is entered.

That is great. It looks flawless. Looking forward to seeing how it turns out.
I guess you stuck to using the i2c extender for the display connection after all?
I`ll update the model later on. I think I will get the controller this week. It somehow took more than 2 weeks for it to go from HK to Norway. By this rate I will get your new controller finished before I get the remaining items for the shield lol.
I will stick to local suppliers from now on I think.

I hope you're happy now. It's all open source.
I hope that you can contribute something useful to this thread from now on, otherwise I ask you politely to stop polluting it.
That's very nice of you to share your design. Sure look interesting since I am also trying to learn the Arduino.

When I order some parts from HK it always takes two weeks or more. Luckily I do order most parts at a local shop.
The i2c extender. For now IŽll stick to using the extender from electroFUN, but in my final design IŽll incorporate a small IO extender to the design and use it in a similar way as the extender from E-Fun. The only difference will be the connections to the LCD. I will add a row of connectors that line up with the LCD's connectors. In my opinion this is the best way to connect the LCD to the controller.
