Well I've soldered a 4N25 in, and I've got it working, but the LCD isn't any where near as bright as if I hook it up directly. It seems it's not getting enough juice.

Thanks!!!

I've managed to get 5 of 4N25 for a few quid. A lot cheaper than I thought they might be. I should have them sometime next week.

I'll let you know how I get on!

The LCD's datasheet is as follows... http://www.blandongroup.com/datasheets/HMC20487SY-LY%20(150x150dpi).pdf It's the Wide temp, 4x20 one. I've had a look at the front panel PCB and there only seems to be two LEDs and two push buttons switches. If there is a resistor on the motherboard, then no, my ...

I really appreciate the help from everyone! If a simple transistor would do the job, I'm happy to use that. But even that I'm a little lost on. And I'm more than happy to do some background reading, I just don't want to end up buying the wrong thing, and blow everything. I've had my XBOX and modchip...

I guess I didn't explain myself correctly enough. You see in XBMC4XBOX there is an option of LCD under smartxx to control contrast and the backlight, but neither of these work for me, even though I have a SMARTXX v2 and a HD44780 compatible LCD. When I said, always on for powering the backlight, I m...

I have a SmartXX v2 chip on a v1.4 motherboard, that I've hooked up to a LCD data screen. The LCD screen needs 5V to operate and 5V for the backlight. I've had to run an alt point of 5V to the modchip because it's not pulling enough otherwise from the pin header. This still isn't enough for the back...

I don't know that much about electronics, but what I want is a relay switch that can handle 2V to turn on a circuit that handles 5V. I want something to happen when the Green light of the Eject button the XBOX is activated. I'm not sure what to look for in a relay that will with those specs and do I...
