Connectorizing the disks, the Positive points need to be solder using conductive epoxy because the conductive film doesn't support the heat. The negative points can be soldered without major problem.

Created this first prototype from the cited design, tested it and communicated the results to SENSORICA and through social media.

Work event: Work - Technician experimental 4.00 Time - Hours Dec. 31, 2013 Done by Tibi

Worked on prototype V2. Assembled 3 buzzers using new connectors. I also tried different methods for soldering the buzzers to the metal connectors. The solution implemented was to use an epoxy. It's not perfect, more work needs to be done in this area.
