Today I made some successful and simple modifications to my WeatherDuino 4Pro Wireless Display.
I wanted a way to move my Wireless display unit form one room to the next, without needing to turn the system off and have it reload each time. I looked at adding two simple Arduino components - the "Lithium Battery USB Charger Module" and "5V DC to DC Converter Module".
Lithium Battery Charger and DC to DC Voltage Controller
With the addition of an "18650 Lithium 3.7V 2,600mAh" battery, I have portable and rechargeable power source for this wireless display unit.
Simply adding the positive and negative wire from the "5V DC to DC Converter Module" to the positive and negative terminals on the "ESP8266 Main Board".
I took some current readings too of the Wireless display unit. It has a constant draw of 90mA with peak draw around 160mA. With a battery capacity of 2,600mAh, there is a potential of 16+ hours of battery standby time; truly enough to get through the night with.
A 10K ohm potentiometer has also been added across the backlight jumpers so the display can be dimmed - ideal for a bedroom. This also saves on the power consumption and drops the constant 90mA draw down to 50mA when dimmed fully.
Next task - housing it all in a nice enclosure.
