Changing green to amber on an Alpine HU

After replacing the blue LEDs in the Alpine stereo for GPMINI, I’ve finally succeeded in changing all the green LEDs too – compare the new and original:


This job was a nightmare, even with reasonably suitable tools at work, due to the tiny size of the “0603” LEDs:


The more I did, the harder it got – just trying to see which end was anode and cathode is almost impossible, and the LEDs are connected in pairs on the board so if one didn’t work, two would be off! In the last picture I’ve changed all of them (took about 1-1/2 hours) but two are off – I had to resolder both because I couldn’t tell which one was the problem 😦

Anyway, it’s done! And it does look much better than blue & green in GPMINI … I originally planned to modify the second Alpine too (that will soon go in GBMINI) but I don’t think I will now; it was simply too frustrating.

(if you’re thinking of doing something similar, I used Digikey p/n 160-1121-1-ND for the two larger LEDs, and 160-1180-1-ND for the many small ones)

F1 Boston

Today I headed out (late!) to meet a group of MINIs for breakfast at IHOP, followed by a rather interesting drive through Boston and down to F1 Boston, a karting facility. Unfortunately the day started badly, with someone breaking in to Dave’s truck during breakfast; we also saw a major accident just inches from us, with an SUV pulling across traffic in front of a car! but thankfully the various incidents on the karting track were much less serious …

I chose not to ride the karts (they look quite small ;)) so I did video & photography instead, but it turns out the lighting is not great and the kart speeds are quite fast, so I’ve got a lot of photos of colored streaks!
