Nokia does love teasing us with its albino-hued special editions, and so it did with the white Lumia 800 back in December. Now that phone is following the color-free road to retail later this month. Other than the eye-pleasing lack of color the phone looks to be identical to its rather more chromatic predecessors, with a 3.7-inch AMOLED display up front and a 1.4GHz processor inside. It looks good, but it just leaves us with one question: how long will we have to wait for a white Lumia 900? Update: According to Nokia's Conversations blog, the phone will launch first in these countries: UK, Germany, France, Italy, Spain, Netherlands, Scandinavia, Finland, Poland and Switzerland.

Hard Soft Synth 2 This is a trimmed down version of the hard soft synth 1. The hss1 used 2 arduinos, one for sequencing and one for audio. This version has both the sequencer and the audio in one arduino, reducing the number of parts allot. The user manuals and scripts can be found here. There are some HSS2s for sale in my shop. If you build one yourself, send me a picture, i would like to see it. Links to useful information about this kind of stuff. A example version of the script is shown below.
