Cutout circuit boards on instructables

Posted in Technology with tags , , on June 15, 2009 by Simon

Apparently Nadya Peek and I were on the same track around the same time :)
Here is her nice instructable on how to make circuit boards using a vinyl plotter:

How to make circuits with a Roland CAMM sign cutter

I prefer to solder the circuit while on still on it’s original backing as the thin fabrics I use melt very easy.

Cutout Circuit Board

Just a repost of my previously posted fabmoment.

Latest touchpad version

For a project at the V2_lab we had to develop a transparent touchpad in textile. For this we needed to create circuit boards that are thin, small, easy to mount on a textile substrate and more or less flexible. To create such a circuit board we started to experiment with cutting copper foil on the CAMM-1 at Protospace fablab.

Tweet Bubble Series

Posted in Arts, Technology, V2_ with tags , , , , , on May 21, 2009 by Simon

We finished the tweet bubble series for Aram Bartholl residency at V2_. The residency results have been presented during V2_ TestLab: Fashoinable Technology. Below the original post from V2_lab blog:

The Tweet Bubble Series consists of four wearable speech bubble prototypes developed in collaboration between artist Aram Bartholl and V2_Lab.

TweetAll four prototypes reflect on the micro blogging service ‘Twitter’; a relatively new Web2.0 platform that fills up the gap between blogging, instant messaging, and SMS. All messages posted on Twitter are public by default and stored as single HTML pages. Due to Twitter’s growing success, the platform is about to become a standard communication tool. The way in which Twitter is used to communicate within a social network is largely shaped by the absence of physical proximity between users and the relative anonymous social exchange that the platform allows. To deeper investigate into the role of this absence of physical proximity and relative anonymous exchange in the use of Twitter, the central question to the wearable speech bubble prototypes is: What would it be like to not only show your latest message online, but to also publicly display it on your T-shirt?

Wearable Sound Experiment

Posted in Arts, Technology, V2_ with tags , , , , , on May 21, 2009 by Simon

The 16th and 17th of May V2_ Institute for the Unstable Media held a 2-day workshop on wearable technology lead by Mika Satomi and Hannah Perner-Wilson aka Kobakant.

After the workshop introduction and meeting round participants were split up into two groups to distribute the wide variety of skills. The background of participants was broad (ranging from industrial designers to fashion designers to hard- and software developers). As the average knowledge of the participants was quite high, the goal of the workshop was ambitious: create a performative sound experiment.

Wireless RFID

Posted in Technology, V2_ with tags , , , , on April 24, 2009 by Simon

Finished my wireless RFID set, from left to right:

  • Desk reader/writer (non-wireless)
  • Receiver (receives the IDs send by the transmitter
  • Transmitter (reads and immediately sends RFID tags over a 433MHz radio link)

Organza touchpad development 2

Posted in Technology, V2_ with tags , , , on January 4, 2009 by Simon

This month I’ve made quite some progress with the transparent touchpad in metallic silk organza. With thanks to Piem who has sewn the thread paths and did the more difficult fabric crafting, I now have a working prototype touchpad.

touchpad internals

The prototype touchpad has 8 sensitive areas roughly the size of a man’s hand. All areas are embedded in a single layer of metallic silk organza. Only a light touch of one or more of the sensitive areas is enough to trigger. In total the pad has five layers (might increase to seven depending on the possible addition of a ground ‘plane’).

  • organza sensitive layer
  • two isolation layers (could be one depending on fabric quality)
  • component layer
  • two isolation layer (could be one depending on fabric quality and presence of ground plane)
  • possible ground plane

The sensing boards are constructed out of copper foil circuit boards (cut with a Roland CAMM-1 vinyl cutter at Protospace fablab Utrecht ) and conductive thread. They work by capacitively coupling a relatively high frequency signal put on the metallic organza sense areas. On the left is the A/D converter board (unfortunately TSOP-16 is too small for cutting).

In the movie I overlayed (slightly out of sync) the touchpad output as a bar graph. Only the first 4 (out of 8) outputs are functional in this test (the most left bars in the graph).

Continued development on the organza soft touchpad.

The basics are working with the CCB’s in place. Much of the electronics (bottom in picture) will be embedded as well in the next generation.
