Simone showed me two more really helpful things: what you can see here is called wire wrapping. It’s a technique to create circuits w/o soldering, and it looks great ;) You have to use wrap pins that you simply beat into the board, then you use a little stick to put the wire around the pin, which is actually faster done than soldering.
Also Simone showed me a kind of “Bible” for people hacking around with circuits: The Cmos Cookbook. This seem to be really useful, it contains all cmos components available including description, picture and explanation how to connect them.
Today’s Lesson was about the IF :lol: – ELSE :sad: command. The physical example we used for that was:IF you turn a potentiometer underneath a certain vale, make the LED blink. To keep things easy we used pin 13which has a resistor built in to let the LED blink. I wanted to make things a bot more spicy and also make use of the ELSE IF and ELSE command, so i decided to make a wiring wiith a second LED on pin 12 that work like that: If the value received from the potentiometer is below 100 let LED1 blink, if it’s between 100 and 300 let LED2 blink, if the value is above 300 switch both LED’s constantly on.
I’ve chosen to join Karolina Sobecka’s Project mmodesty. We’ll build o low-cost virtual camera system. Therefore we will hack a bunch of single-use cameras in order to make them readable and release at the same time.
1st day: We started to break up some PDA readers that use the same interface like the single-use cameras.
The plan is to connect 30 cameras to one arduino in order to release the shutter simultanously. To do so we need to extend the outputs of the arduino, which originally has only 13 outputs. So, to get the ammount of output needed we built a Serial to Parallel Shifting-Out with a 74HC595 chip as explained on the arduino hompepage.
Since the hardware tasks of the day were fulfilled with excellence we started a test shooting with one of the cameras. Our testsetup was a half circle with a radius of 3.2m, with marks every 20cm.
this is the output of the first testshooting: file formats troubles
part of the club transmediale were the xxxxx-workshops which where held in the ballhaus naunyn. i tried to participate in all the workshops, but due to lack of sleep and a missed flight to berlin i only participated in the digital theremin workshop which was held by andrey smirnov from the theremin center in moscow and derek holzer. smirnov introduced us to the history of the known theremin instrument and lots of interesting info about leon theremin and his other inventions and his connections to secret services.
after a short introduction of pd by derek holzer, who also curated the worskhop series together with Martin Howse, we started to play around with the small digital theremin boards connected either via arduino board or via the standard mic/line input of our computers… pretty cool stuff the small digital theremin boards – because of digital tuning of the two oscillators it is very convenient and usefull even for installations, because there is no need for manual tuning which is a problem for analog theremins. so this was really a very good and interesting workshop which i was happy to attend. it was organized by pickledfeet and they are very active in knowledge transfer – so watch out for upcoming events.
little advice in the end : don´t try pd on macbooks with leopard yet – it nearly destroyed my computer, because it didn´t go to sleep mode after i closed it.
