Enjoyed your blog post - some great insights, solid final results and at about the right level of DIY. Could you give a specification for the LED pucks though please? The Aliexpress link is dead.
Ah yeah, sorry about that. I'll have to update the blog post.
They are sold by a variety of vendors, but generally you're gonna look for the 3-pixel 30mm pucks. They come in either cold-white or warm-white varieties, and a slew of different voltages.
You can buy a whole "kit" from the same vendor I bought my stuff from here[1], or the individual lights[2] and the tracks[3]
You can also buy similar products from some US local stores, like WasatchLights[4], YourPixelStore[5], or from Gouley[6], who appear to be the original manufacturers of these. But I've had good luck with PaulZhang's store on AliExpress, so its the one I can attest to.
