at some point, you realise that foam lined box isn’t going to cut it. to hold cable, power supply and controller neatly together, and do it without squashing requires some form of carefully shaped insert. hence a night of cardboard, metal rule, craft knife and ever-refining design print-outs.

Just a quick reminder that if you did want to order one and haven’t so far, we’re now in the last 48 hours for ordering.
Given the delays in opening – banks and paypal, urgh! – I’m going to hold orders open for an extra day. Orders close 23:59 Monday 10th, GMT.
It’s now or never, world!

happy to report the festival of ideas has won a business to arts award. it was a really satisfying project to be part of, and i’m really proud of how it responds to the ‘liveness’ of that kind of live event.
interestingly, it won the ‘staff engagement’ category. my research on liveness has led to audiences and interaction, so ‘staff engagement’ is a good fit there. what i find interesting is that in having recently talked about my ‘engagement with liveness’ agenda in entrepreneurial circles, it’s the ‘organisation innovation’ consequence of this that really hit home to them… and here we have that reinforced. there were plenty of other categories the festival of ideas could have won in, and plenty of other aspects of the event they could have chosen for that accompanying photo.

with two huge milestones, it’s the point of no return: the site with price, spec and ordering info went live yesterday at sparklive.net, and i’ve just committed real money to get the first manufacturing task primed.

“The *spark d-fuser lets you cross-fade between laptops. It’s compact, affordable and — after quite some time(!) — I’m now ready to make the manufacturing run. So this is the final prototype, and with this I’m making this video to demonstrate the features and functionality so you can decide whether you want to have one yourself. If you do, you need to order now so that it can go and be made as part of that manufacture run.”
https://vimeo.com/tobyspark/sparkdfuserdemo
the video doesn’t look like the above, but thats how i remember it: a huge amount of faff to get the point of being able to knock out not far off a one-take wonder. you can probably see the time in keynote presenters display, i’m not sure i want to: the afternoon turned to evening and then night, and i ended up returning home when the tube had started up again. note to self: start in a studio instead of trying to transform the office most of the bits and bobs were already in. at least the night allowed me to hijack a reception area, even if it meant ripping up half the floor to find the cabling.
i’m super happy to announce that the site through which i’ll be detailing and selling the *spark d-fuser mixer will be going live next friday, then will start taking orders for a week starting the friday after that, and on the first september the manufacture run will start. huzzah!

it doesn’t look like much at the moment, but this is the first step into my research group at university doing a study on real festival audiences at real festivals. i’m developing an interactive map / timetable app, which will have quite some interesting features and opt-ins by the time we’re done. the promoters we’ve been talking to already have an interactive map of sorts, i’ve already done some interesting things visualising live events, and of course there’s my phd on audiences and interaction.

drawings do not a mixer make, but in their finality for production and retail they make things that much closer.

things are building to a crescendo. as promised the software that runs the controller will be open-source, and so here it is being released.
http://mbed.org/users/tobyspark/code/SPK-DVIMXR/
notably -
i’ve also been corralling the OSC code available for mbed into a library: http://mbed.org/users/tobyspark/code/OSC/
for history’s sake, and perhaps it will help any hackers, attached is a zip of the arduino code i had before the leap to mbed was made, v07 to today’s v18. none of the interface goodness, but has got the fast serial communication technique i came to along with keying etc.

file under ‘so glad this worked first time, because if it hadn’t i wouldn’t have known where to start’.
as alluded to in the last mixer dev post, the ethernet jack wasn’t just an ethernet jack any more. my first pcb design had the ethernet jack as a ‘magjack’, which has the electrical isolation to protect the circuit from rogue cabling within the jack and was simply a case of leading the signals from the mbed to the jack. however, all the magjacks i could find could not in the end fit within the final tolerances of pcb position and case height, so i had to move to using a discrete isolation chip and a low-profile RJ45 socket. and at that point, the now plain RJ45 socket was suitable for direct connection of DMX - there’s a standard RJ45 pin mapping as well as the XLR type normally seen. so version two of the pcb, in addition to the physical fit issues, had two subcircuits for ethernet and RS485 leading to the socket, carefully electrically isolated and switched.
however, the assember did a snafu and a wrong part was fitted to power the RS485 subcircuit, and it blew on my attaching power. the advantage of it being a subcircuit is that it didn’t take anything down with it, so with an otherwise operational board, the DMX side was sidelined. some months later now the reworking has finally been done, so i made up some RJ45-XLR DMX patch cables, linked in a contributed DMX library from the mbed repository, worked it into the controller’s code, borrowed some DMX gateway hardware… and it just worked! fabulous.
in which i set out my stall, hawking the wares and ideas that have helped make my ‘post-vj’ life. half an hour, somewhat off the cuff, and probably ill-advised in parts. the bulk of the talk covers some of the backroom work and event life of the dvi mixer hardware and screenrunner software projects, but contextualised by how i. vjs should work towards exploiting the liveness possible in their practice, ii. which should lead to a more rewarding, less clichéd life, iii. and one more profitable and sustainable.

to rome for live performers meeting, once an annual institution for me. a weekend in a nightclub is always a strange thing, but being in roma with friends old and new cuts through all. some of whom were old visual berlin types staking out interviews on the rooftops for their new scope sessions project. picture are valerie and david talking about node and vvvv. before that, the light surgeons and i happily bantered back and forth around live cinema past and present… the kind of conversation that just doesn’t happen in the london day-to-day.
after being one of the forces behind qmedia’s inaugural open studios last year, this year i was playing behind-the-scenes fixer, and with things fixed was able to get a few hours hacking on the dvi mixer before the show wrapped. even better, having established last year the reward of documentation, there was now a film crew looking intrigued and asking me to explain my research…

for a few fractions of a millimetre here and there, this is pretty much a whole new pcb design. it also meant no magnetically isolated ethernet jacks (the mag in magjack should really be magic instead/), which puts you on a path of doing that isolation your own circuitry, and that… that can put you on the path of feature creep.
yep, feature creep it has, and with that more delay. but for a very good end: that ethernet jack can now do more than ethernet…
having worked some magic to visualise the actions back into the venues in realtime, aiming for a positive feedback loop of commitment, my legacy contribution was a film to capture the activity and commitments of the event to show as part of the finale - a review as celebration and reward that developed over the phases of change nation.
here’s the final version capturing the full three days. i’m proud of it, and it shows how these posts have barely scratched the surface. http://vimeo.com/39511237
there’s also a download of the poster image made for this post below, at 5000px wide.

to the country estate in the heart of dublin: farmleigh house, for the public day of change nation. and not just to the grand house itself – state photos of obama and northern ireland peace process on side tables, first prints in the irish language in the library – but to a boutique festival site pitched specially on the lawn. it was a wonderful day opening out the process to the public, starting with the two hundred handwritten commitments to action from ministers and all sorts of power brokers lining the walls of the main tent, and finishing with many more commitments made as the ticket holders brought their skills and connections to bear.

another day, another dublin landmark: dublin castle. a regal setting for an amazing day of action, as if day one were a dress rehearsal. the ‘live’ page we worked so hard on says it best, go take a look: http://changenation.org/live
this was also the day i was charged with disappearing for a few hours to produce the event-so-far look-what-we’ve-achieved video, quite the rabbit out out the hat. part video edit, but mostly keynote backed by a judicious music choice and the wonderful photos by sean and yvette. oh, do i love keynote.

day one, and tourist location number one: the guniness storehouse. lots of briefing the facilitators, lots of wrangling screens, pipelines and all things digital that that weren’t the website, and far too much time trying to get posterous to work on everybody’s phones. but through it all, the website morphed from a brochure to a live account of the event, and the commitments to action were coming in and becoming part of the public record.

to dublin, to save ireland. 50 social entrepreneurs had been flown in from around the world to kickstart the adoption of their ‘proven solutions’ in ireland: the three day event was called change nation, and that really was its aim. ashoka have that kind of clout, and aren’t afraid to use it.
working again with event mastermind boz temple-morris and digital maestro stef lewandowski, their agenda was clear: stop three days of networking from being just a talking-shop. action and accountability needed to come out of it. for me, it was a opportunity to be at the heart of event conceived around audience-audience interaction, where facilitation and legacy were conceived hand-in-hand. stef has an excellent write-up on his site.
i arrived the day before to find stef explaining his digital strategy to ashoka. tip: if you want to impress somebody, draw the diagram upside down across the table…

package was waiting for me, opened the box: two assembled pcbs, all looking as they should.
to my utter amazement, the electronics all work out: once the pinouts were updated in the mBed firmware, its talking RS232 to the video processor without drama or debugging. to my double amazement, after a quick primer on SPI and decyphering the oled’s datasheet, a test program incants the screen into life, and some time after that the random pixels of an uninitialised buffer have turned to a pattern of my coding. some image editing and two processing sketches later, i have the byte sequences to display a full screen image and typeset my choice of pixel font. the test program fleshed out and re-rolled as a library, and we have the above sight. given the delays the screen has caused since 2009, its so satisfying having this work as per the data sheet, as per design, out of the box; and not even relying on other people’s voodoo: my library, from scratch.
of course, things are never quite that simple. the electronics check out, but the physical fit requires some rejigging – note to self: order the enclosure in advance next time, no matter how well dimensioned its spec drawing may seem. a millimetre here, and a millimetre there has now forced a complete re-layout of the PCB.
aaaand: the ultimate irony? the physical fit issues weren’t just components hitting case internals. what you can’t see in the photo are 40 jumper wires coming out of the mBed’s socket on the PCB leading to a displaced mBed sat in a prototyping block. for all of the correct design and manufacture, these assemblies are compromised by a square peg (mBed pins) not fitting into a round hole (a quirk of the socket strip i spec’d). tssssch!
