Today I decided to experiment with controlling multiple EL strips simultaneously. This works similar to the previous EL setup, though I needed to add an additional triac into the mix, as well as split the connections from the inverter to connect to the two strips. Also needed to add an additional resistor connection from the microcontroller. This created a lot of exposed wires which I found out give quite a shock.

As you can see from the photos, the setup is becoming more and more complex, and I am getting electricuted more and more often. The circuits will definatley be isolated before a wearable solution becomes feasible.

ISSUES: this setup is running using a 9v battery powering the inverter and a 12v AC adaptor powering the microcontroller/Bluetooth modem. This is required currently because the Bluetooth modem requires a lot of power. It has been suggested that I use RF rather than Bluetooth for wireless data communication, however a RF solution has yet to be identified. The Bluetooth has thus been reliable, and we may need to tape a bunch of 3v coin cell batteries together rather than have a 9v battery and ac adaptor (which is not feasible for a wearable display).
