Demon RGH NAND Status LED mod - Guide

[theagent]

One of the features I really liked about the nandwich dual nand method was the optional status LED on the RF module, which powered the debug (red) LED when the RGH NAND was selected. I have the Demon's switch on the back of my console, so I can't always tell which NAND is selected, since I can't see the LED. So, I decided to add this feature to the Demon.

Here's a guide.

Here's the outcome when the RGH NAND is selected...

And here's the Youtube video that shows it in action.

This can also be done with the second style RF module. Solder the collector lead to the right pad of R20. Sorry for the lack of picture.

Just wanted to add that lead 1 of the NPN is going to ground. You can ground it anywhere you'd like. I took the pictures before I soldered the green wire from the RF board to the NPN collector lead. They should be connected. If you can't tell from the picture or the notation, there's a 100ohm SMD resistor from the base of the NPN Transistor to CR_EN. You don't have to use an SMD resistor.

Good concept, but personally I think the LED being constantly on would bug the crap outta me

I can understand that. It's actually pretty dim with the case / front panel on. So just feels like a standby LED similar to my media center and receiver's light.

Not for everyone though, I get that. I developed a back problem about 2 1/2 years ago, makes it difficult to sit and get back up multipe times... so I've been trying to automate everything I can.
I created a remote to switch between NAND's on the Demon, so this was just a convenient extension of that. My other project with the auto-switching dual HDD's didn't work so well, but I've been thinking I'd just go the USB route and have the internal memory disable when the RGH NAND is selected.
