Penelope — fabrication process (photos only)

First prototype of physical construction, with conductive thread running in the warp.
Cut pieces of the frame for the final prototype, ready for assembly. The spacers for the warp and the rigid heddle are lasercut acrylic.
Assembling the frame for the final prototype.
The assembled frame, with the roller bars and brakes added.
Dressing the loom: beginning the tie-on for the warp. The loom is dressed from back to front, so this is the back bar.
The warp is spaced and rolled onto the back bar.
The warp is threaded through the rigid heddle.
The rigid heddle is raised and lowered to open the shed.
Final prototype with the circuit and pulse sensor connected.
Peer testing and feedback session
Early prototype of pulse data visualization, taken when the user was not weaving. The wave structure of the pulse is extremely clear.

An example of pulse data with low levels of weaving interference. The wave structure of the pulse is still visible amongst the noise generated in the circuit by the weaving.

Pulse data with higher levels of weaving interference. The black lines crossing the image approximate the moments when the shed was opened and closed, indicating the completion of a line of weaving.
