 I want to measure the voltage over time as the device discharges so I can calculate how much power each component uses. I will run the following tests: I want to measure the voltage over time as the device discharges so I can calculate how much power each component uses. I will run the following tests:
  
-  * JP1 open, disconnecting the LED and microcontroller,+  * JP1 open, disconnecting the LED and microcontroller from the supercaps,
     * This should measure the self-discharge and leakage across the Zener D2.     * This should measure the self-discharge and leakage across the Zener D2.
   * JP1 closed, running unoptimised naive code, blinking the message "ss s"   * JP1 closed, running unoptimised naive code, blinking the message "ss s"

 +I don't think there's much point in trying to further improve energy efficiency of the code. The next steps might be adding features like multiple message sequences, and/or improving the space efficiency to fit more/longer messages.
