    Thanks for the link Bryan, that second picture shows the Danube in the background.

    I had a bit of a humbling experience last week when we spent a few days in the factory where the boards were being assembled. It's strange watching something you've designed being assembled on a pick and place robot assembly line... and wondering if there are any artwork errors in the board layout.. (luckily no errors.. )

    The production run was 5000 boards and they did it in 16 hours machine time, the pick and place has two independant heads each with 6 component feeders, all up it can do 22,000 parts per hour.

    I did take more pictures in the factory, but I need to get some kind of management permission to put them on-line.



    For those interested, the radio receiver is a Silicon Labs Si4705, and the processor is a PIC18LF14K50, the code does real-time single point DFT using the Goertzel Algorithm, (written in assembler) and does 37,500 samples per seond to decode audio control tones for controlling the led lighting...

    And, no BT, I still haven't got to that Porsche Exhibition, and still lots of beer brands to try...

    Regards
    Ray

    Hey Ray,

    Naturally enough the electronic stuff just whipped over my head but the beer didn't. It just so happened that the day after your last post I was at Dan Murphy's and chanced upon a box of Zipfer, brewed in Linz. Not bad. In fact I'm guzzling one now.

    BT

    ps. when do you think you will be back home?

    Hi Ray,
    Certainly beats the hell out of soldering all those SMD components by hand....... and not a dry joint to be had i'd bet.
    Is it only a double layer board or more? There must be a good 50 components on there, looks like a neat package

    Oh, and could ya stop with the beer talk!!! Your making mister "i don't drink much these days" very thirsty!!!!

    Sorry for all the beer talk Ewan, this one is for BT, apologies for the picture quality (phone camera) I was thinking of Bob drinking Zipfer, so I took the picture at lunch time today at the Bila supermarket near AEC,



    Zipfer is probably one of the most popular brands, Ottakringer is up there as well, and if you like wheat beer Erdinger isn't too bad.

    A 6 pack of half liter bottles of Zipfer will set you back 5.34 euro, or about $A7..

    Radler, is a sort of beer shandy with lime..

    Home in about 5 weeks, I'm missing the workshop..

    Sorry 4-6-4 I won't get to Germany this trip, but there is a railway museum in Linz, I recall they manufacture electric trains/trams here, unfortunately not steam..

    Regards
    Ray

    Hi BT,

    Might be a bit touch and go, we fly out on the 7th, so we are back on the 8th I think?

    Regards
    Ray

    PS If PDW is listening, any time after that is ok to pick up that big faceplate.

    We'd be cutting it a bit too fine Ray. If my daughter stays the duration, she'll be at RMIT for another 3 years. Plenty of rendezvous opportunities.

    Last night was the Klangwolke event, and we had 90,000 people in Danube Park.

    Here's a taste of what it was like.

    More Later....

    Tired but happy

    I’m almost lost for words, how some bloke and his son from Shepparton, end up in Austria, working for some mob called ArsElectroninica, and pulling off some serious public event in front of 90,000 people at some thing called a Klangwolke event.

    Truly lost for words.

    Crocodile Dundee, didn’t even pull that off. This really needs a good old fashioned slide night, to explain how you have pulled this one at of your ####.

    If a long legged, late teen girl, makes it as a dancer, at Moulin Rouge, they get an article. Example here, The Age none the less.

    Aussie girls kick on in Paris - Arts - www.theage.com.au

    My bet is, you blokes have hardly raised a mention in the Shep news.

    Regardless I’m proud of you. Now here’s the joke.

    Did they mistake Austria for Australia?????

    Phil.

    Here's a bit more video

    [ame="http://www.youtube.com/watch?v=4vNBe--zyi8"]Linzer Klangwolke 2012 - YouTube[/ame]

    Some random stuff..

    A total of 28 big outdoor projectors doing the projection on the buildings, were controlled by timecode (LTC) from our system, we used the right stereo channel for timecode and the left channel for control of the dancers in led suits, the letters people had made and were carrying, and the super bright led stips on the towers and poles, and start signals for the robots on the ships.

    Sound system was 250,000 watts, pretty impressive setup for correcting for reflections and matching to the environment. (Good group of guys doing the sound stuff).

    The letters with led strips were all along the river bank, and there was around 4000 of them, looked amazing..

    Someone calculated that there were something like 450,000 leds...

    There are more videos on you tube if you search for Klangwolke 2012..

    The drones were from ascending, ( nice quadcopter) controlled by gps with a 3d animation, a total of 41 drones flew, in the most ever flown in an outdoor formation. A few months back a group in Cannes did an indoor event with 30 drones. This was more drones, and outdoors, which is a bit trickier..

    Now, I can't wait to get back to the workshop... suffering from workshop deprivation.

    Regards
    Ray

    PS Thanks Phil... I'm sure it was a spelling mistake..

    There must have been a lot of last minute dry runs on all the hardware, not to mention programming to fine tune the overall effects. I'd really appreciate a rundown with several diagrams and slides on how it's all done. I can appreciate though, you'd keep a lot of the product secret though for future productions. Was much of it made to use existing protocols and signalling specifications?. Do the people composing the show say they want systems capable of switching such and such a load using such and such a signalling method?, or is it all left up to you to come up with a system based on a customer saying "We want something like the stuff in this video".
