Subject: Re: [motm] Steam Powered Sequencer

hello there,
it's an old 1920's model - so runs on meths (!!!) which is handy
the soundtrack isn't sync-ed to the picture - this was just my first attempt, the entire track is around 10 minutes long, the first six minutes are attempts at getting the transmission running :-)

no throttle on this thing - it's either running or it's stalled - but i guess with gearing i could adjust the rotational speed of the dynamo

not sure about a 5U panel - when my carpentry skills improve, i've a MFOS that's screaming out for another case

cheers

Very interesting, Paul.  What's the fuel source for the steam engine?  Could see the flame in there.  Was it slowing down at the end because the engine was running down?  Now you need to add voltage control to the steam engine to control the throttle!  And make a 5U panel for it :)

hello all,
i've been quiet for a while, i recently felt compelled to buy a steam engine on ebay, and then hatched a plan:


you'll recognise the MOTM120 sequence with a little variation courtesy of some CGS modules
the dynamo is just regulating the tempo of a MOTM320 LFO via it's V/Oct input

i did spend most of the bank holiday monday building a steam powered pulse generator (add a rotating disc and a pair of commutators) but the steam engine wasn't powerful enough to power my clunky transmission (bits of old tape machines, the shaft from a coffee percolator, bits of hard disk and a hairdryer)

maybe next weekend :-)

cheers
