Spidious almost all Red LED's are 1.7 to 2.8 Volts you will need to put a 47ohm resistor inline on your positive lead. that way you won't burn out the LED. hope this helps

I did this mod a little differently, since the two times I've left the DX7 on was with the simulator, I wanted the light to work when the sim was connected (the 3.7V supply shown only works when the switch is on), I used a 12V LED with the -lead on the charge socket and the +lead on the buddy socket, this makes the light work both ways.

I have an abundance of 12V bright blue LEDs with the stainless bezel and nut if anyone is interested I'll turn em loose for $2.25 each mailed in the US PM me if interested.

I can see the value of an led to let you know the tx is on. But I still wish for a warning system like a buzzer that goes off after 5-10 min of inactivity.

Hi there and thanks for that very detailed mod! I too added an LED indicator to my DX7, but did it different to yours, and wondered if you had any comments. I used a larger value resistor and connected to the 12V supply ( I use a LiPo pack ) on the switch terminals. All seeems to work fine, EXCEPT the LCD display now has a few vertical /horizontal lines showing for a few seconds after switching off. Any Ideas anyone ? TYIA

It would be so great if I could back lite the screen on the x9303. I have no idea what that would involve, but I would be willing to try it. Not during the summer though, I have a feeling it would take me a long time todo.

I recently read a diy on just this topic of adding a backlight to an lcd. I managed to dig up the thread at http://www.electronics-lab.com/blog/?p=904

I would also like to know how you did this, out of all the backlights I see yours definitely looks the best.

Default dx7 backlighting

is this (re: DX7 backlighting mod) just a pipe dream or isn't anyone going to finally explain HOW they were able to accomplish this feat? It seems nonsensical that people take the time to post that they have done it, but then remain silent whenever asked for details. What's the point of sharing then? Just to show off, I suppose...congratulations.

Thanks for listening.

Thanks SB, just finished. Two hours and it was sorted. One thing that that is worth mentioning, it is a good idea to thread the wires from the LED though the hole in the power switch board to avoid the board from bending the LED legs. I didnt, but kinda wish I had. LED is working fine, I was worried that the bend may have caused a wire to come loose...

SB.. Thanks for that.
I just completed your tutorial. Fantastic. The step by step was a blitz, not unlike the vids from Finless. Really great.
The only mod I needed was to frost my led. Yours looks ok in the pics but mine was very directional and even in the daylight was blinding. So I frosted it with fine sandpaper and it rocks. GREAT WORK! ***
