I’ve been finding lately that I leave my RaspBMC Pi on all week after watching a film at the weekend, as I just simply forget that it’s on due to their being no visible ‘on light’ – unlike traditional TV boxes that have bright LEDs.
A quick, easy and subtle modification with my case has fixed this problem, come take a look…
Keeping it simple
This wasn’t intended to be a project or anything remotely clever, I just wanted to quickly fit an LED that lit when the Pi had power. I wasn’t interested in any kind of code for this one.
I decided I could make use of the standard GPIO power and Ground pins and just hook these up to an LED. Most generic LEDs in my bits box would require a resistor to be soldered in line to stop things going pop, but I wanted it simpler than that. I found some 5V LEDs in the Maplins catalogue that wouldn’t need any messing around – I could hook them directly to the 5V pin. Sorted!
Putting it together
You can see what I did by looking at the images below, it was very simple. I cut down some female jumper wires (1 red 1 black) and soldered these to the legs of the LED, giving me a very simple circuit. I also covered the bare connections with some shrink wrap, just in case.
A quick look at the shape of the case and the location of the required GPIO pins gave me a rough idea of where the LED needed to go – I didn’t want a load of slack wire in the case. Out came the drill, with a drill bit selected to match the LED panel mount fitting that I also got from Maplins. *Drvvvvvt*…done.
In went the LED panel mount fitting followed by the LED, after which I hooked up the 2 wires to the 5v and GND GPIO pins directly. The job was done!
Here’s what the case now looks like from inside…
…and the outside:
Simple as that! Keep an eye out for my upcoming blog on a new case I have ordered to replace this one…wood is the theme…
