Hi. I build recently a little USB-powered desk frame around the Photon and a low power micro ePaper display. It starts regularely (e.g. every 5 minutes) a webhook and updates the screen if the status changed somehow.
Now I was wondering if it possible to upgrade the project to a battery driven, cable-free picture frame with Bluz … having a mind a lifetime of one year before recharging an internal 3000mAh li-ion accu. Please can I ask for your experience… do you think that is realistic?
My rough calculation used 80µA deep sleep current and 8mA for the BLE radio being ON for 10s within a 5min periode. With these numbers I am getting 340µA in average which equals to 363 days based on a 3000mAh accu.
Please let me know your opinion…
Thanks in advance!
