Crazy LEGO Xmas

December 23, 2010 · Posted in Uncategorized 

Desmond Dodecahedron has the craziest way of celebrating the season I’ve seen this year: just build a giant Christmas tree from LEGOs, then use visual programming environment Max/MSP and some custom electronics to trigger tunes. Desmond writes:

Once I discovered that the word “advent” was actually an abbreviation of “audio event” and the fact that we have had lots of snow in London – I decided to create this Christmas Carol note filtering tree. (in this case it is actually a midi event tree – but you get the general idea). Each pitch class of a Carol i.e. all the Ds or all the Fs are allocated to a Lego door. When the door is opened, a midi file is played and the notes are sent to a vst synth in a Max Patch. The doors have small magnets which trigger a reed switch. I built a couple of resistor ladder multiplexers so that I could use nine doors with just 3 analogue ins of a Make Controller. This device could be used as a sophisticated “Name that Tune” device – fun for all the family – if that’s what your family considers to be fun – unlike my own. Keep up the good work with CDM – and a festive maximum to all your readers – Des
