8.30 am. I uploaded yesterday’s diary, posted emails, and began the last of the individual tracks contributing to The Floating Bible project: Matt. 20.25:

9.30 am. Today I prepared for the circuit-bending demonstration tomorrow. While the technique is straightforward, the framework of performance and delivery is not. The name of the game is ‘hazard’, for several reasons. The circuit board is:

  • vulnerable. Having been removed from the protective case, its components and wires are apt to work loose or break;
  • unstable. The process of short-circuiting sometimes involves routing the full 3-volt DC current used to power the device through components that may not be designed to accommodate that charge.  As a consequence, they either weaken or burn out;
  • unknown. There is no guarantee that any productive sound will emerge from the process of probing the circuit board;
  • inconstant. There is no guarantee that, once located, a productive sound can be found again (even when the same two nodes are connected) or sound again, as it did previously.

Because I’m adapting electrical devices to functions that they aren’t supposed to serve, the system throws up a good deal of earth-loop hum (a 50-Hz frequency that can drive a sound artist to distraction), which has to be lifted at source. 2.00 pm. Then, a power supply connection failed; then, the Sony Walkman failed; and, then, the transistor radio failed. Better now than tomorrow. They were all, bar one, fixable. However, the broken device encouraged me to try a new technique: applying a current directly to the circuit board’s nodes, rather than via the normal DC input. Other, useable, and unforeseen/heard noises resulted. Principle: a failure may give rise to an opportunity that would not otherwise have been grasped, had it been a success:

Circuit board handboards (Oct 2014)

Having thoroughly tested the equipment, it remained for me to box it up ready for transport:

6.15 pm. Practise session 1. 7.15 pm. I began setting up the handboards at the School. I’ll now be able to install the whole rig, section by section, in the single gallery tomorrow morning. The School’s ‘ghosts’ didn’t show or murmur, yet again. They’re a dead loss.

9.40 pm. Practise session 2.
