    Workshops

    All your segments are belong to me

    Saturday October 11th 2014, 9:30-17:00 as part of the Wear It Festival in Berlin, Germany

    In this workshop we will build our own segment displays and attach them to our bodies, turning ourselves into platforms for personal signage. What text would you like to display on yourself?

    Segment Displays are made to display alpha-numeric characters, such as the 7-segment display which can depict the numbers 0-9, and the 14- and 16-segment displays which can also show all letters of the alphabet. When designing our own segment displays we do not need to stick to the shapes and arrangements of the industry. Individual segments can be any shape, size and colour we want. We can create and design new segmented fonts for displaying text on our own segment displays.

    In order to build our own wearable segment displays we’ll use an ATtiny microcontroller and the Charlieplexing (n*(n-1)) technique to control up to 20 individual LED lights from it’s 5 i/o (in, out) pins. We will make a little breakout board for the ATtiny microcontroller so that we can sew the LED connections into fabric and then solder the surface mount (SMD) LEDs directly to the conductive thread.

    This workshop covers a variety of skills including: reading datasheets, understanding charlieplexing, soldering, sewing, programming, designing and building wearable technology.

    This workshop was inspired by the DressCode Workshop approach of celebrating LEDs, rather than shunning them as kitsch or light pollution, and by Trafopop‘s work in making wearable LED displays for animated
    graphic designs.

    Workshop Details:

    Date & Time: Saturday October 11th 2014, 9:30-17:00
    Location: Betahaus, Berlin
    Participants: 10 max.
    Cost: 60 Euro

    Charlieplexing

    This is the circuit schematic that shows how all the LEDs are connected to the microcontroller pins.

    Charlieplexing Chart

    Based on the 5 pins of the microcontrolelr that we use this chart maps all their possible combinations to segment numbers.

    Custom Flex PCB

    Plotted Flex PCB >> http://www.kobakant.at/DIY/?p=5371

    Make sure you place the ATtiny into the socket on the flexible circuitboard the right away around. The + pin of the chip should line up with + pin of the socket. The following illustrations show the various layers that the flexible circuitboard is made up of.

    // set the pins NOT connected to the LED in the segment to INPUTS:

    // set the pin connected to the LED’s GND pin to LOW:
