So far the concrete (actually wooden) results of my two months in Singapore:
Above are two shots of the beaters for the Kenong (3 units from a set of 10)
Above is the Kendhang Ciblon (medium-sized drum) and one of the 2 beaters I made for it.
These weren't even the biggest gongs in the full-scale gamelan I borrowed them from.
The beater for the Saron Panerus.
Closeup of the solenoid mechanism. About as simple as you can get. Many thanks to Professor Jan Mrazek, the the head and teacher of the NUS gamelan group (Czechoslovakian, but an absolute Southeast Asia geek), for his very generous loan of the instruments, and to Varghese Paulose, the head of I2R's fabrication laboratory, without whose enthusiastic and welcoming support I wouldn't have been able to move a single step on this project.
