it's been a minute!

seems like forever since i last posted something up here... let's see what's been happening since then.

*installation progress - i should have some nice pics of the sculptural elements by the end of the weekend as they were cast in aluminum last week and gabrielle is working on them this weekend. i decided to change around some ideas for the sound element - originally i was going to use 8 separate recorded loops that were to use ISD2560 voice recorder chips, but they're pricey and the cost per loop will be rather high... instead, i'm going to buy 8 old school ipod shuffles! much simpler/less work and i can focus more on making the VCA/opto element function better - initial results were positive using an LDR to control the voltage, which in turn controls a channel on an SSM2164 quad VCA chip, which is a nice and compact way to get all 8 VCAs in 2 chips. i need to further work out some smoothing of the control voltage so the on/off triggering is not as abrupt.


more info coming on tuesday.

*the backyard garden is in full swing! tons of tomatoes and peppers coming in with beautiful cornucopia of herbs including italian basil, thai basil, lemon balm, marjoram, mint, oregano, thyme, sage, tarragon and rosemary! YESSSSSSSSS

*goddamn i need to get this custom gallery up on the site - seems like the majority of orders coming in have been for custom work anyways so it would make sense for people to be able to peep stuff out without having to go to the forum. just thinking out loud here.

*trying to get the best friend out and solidify a final design for the mountain range, some other random stuff - delay, dredging up old circuits, etc. i've got more shit on my plate than is probably good for me, but i guess what it comes down to is that i'm just a fucking workaholic... better to have the work than not, though. no complaints here.

blah blah more ideas and art installation ideas

*the first run of 15 sparkle motion treble boosters is officially sold out! the response has been overwhelmingly positive so far, so i'll be moving to production of these relatively soon (expect to see them at dealers at a slightly higher price) - just need to iron out some design details, etc.

*some possible drastic changes on the mountain range. working out the details...

*something very secret and very special which will be available at the end of august/beginning of september... ;-)

*making progress on the installation - still just kicking around ideas, but at the moment i think it will roughly be an array of 8 separate voice recorder circuits, each controlled via a light resistor and VCA. the idea here is that the 8 recorders will play back different loops, each of which contributes to a larger composition. the LDRs will be placed on the different sculptural elements of the mobile and when viewers get closer to the work the amount of light will change on the LDRs, which in turn will change the voltage on 8 separate VCAs, creating a swelling type of effect. i still need to suss out a decay feature so that the sample will continue playing when you walk away from a particular element, but i don't think that should prove too difficult. aaaaand i still need to compose the piece...

the block diagram is pretty simple:
(LDR -> voltage attenuator/booster circuit -> LED/LDR voltage control) -> VCA
voice/sound recorder circuit -> VCA -> speaker (x8)
