Removing LEDs from a Sony CDX-GT43IPW

Having some time this evening I opened up the ultra-bright LED-bearing faceplate from Danielle’s new car stereo. I was originally hoping to replace the LEDs with red or green ones, but after seeing that some are part of the tactile switches I decided against that. Looking into things by plugging the bare PCB into the head unit (photo) I found that the most offensive LEDs were those under the horizontal translucent buttons, with two of them lighting each button, and the ring around the chromed selector dial.

The decision was made to remove one LED from under each of the translucent buttons and one from around the ring. The LED removal went well, save for discovering that the ring LEDs are wired in series, so removing one turned off the entire ring. Still, the final result is much nicer. The stereo now lights up blue, but it’s no longer a glaring blue which makes seeing the road at night difficult. If you compare this photo from last night to this one from tonight you can see how much more reserved (and appropriate) the illumination now is. The loss of the knob ring illumination isn’t really a concern, as it’s the only knob on the device so it’s easy to find and other light glinting off the chrome finish makes it easy to see anyway. The tradeoff for less irritating light is worth it.

Interestingly there were two discreet sets of solder pads for each LED, and some silkscreen on the back that indicated selections for amber and green LEDs. I suspect that other similar models of this stereo offered the other illumination colors and this particular model was just for Target, or perhaps low end markets, or something like that. Or maybe this board is just fitted differently when used in other higher-end models…

Cross-Country Skiing

Today, for my first time since a ~30 minute session in fifth grade and Danielle’s first time ever, we went cross-country skiing. At 11am we met up with Erik, Kristi, Nick, Marty, and Jon at Stony Creek, paid the $20 to get some (fairly decent) rental equipment for the two of us, and headed out. While difficult, I managed to not fall and enjoy it, although neither Danielle nor I could keep up with everyone else. Danielle fell a few times, some of which were frustrating and others were comical, particularly as Marty then slid right into her.

It’s quite a fun activity and a nice way to get outside in winter time. Since there’s loads of local ski trails available, I really think I’m going to consider picking up some skis and equipment. After all, all that’s really needed is skis, bindings, boots, and poles. While initially saying that she never wants to do it again, Danielle did say that she’d probably give it another go, possibly in a few weeks or sometime next year.

Here’s the photos taken today, including the one above:
