Need A Tool-Make A Tool

I watch a bit of blacksmithing on youtube and something these guys often say when they are building something is Need A Tool, Make A Tool. Its a good way to think about life, why run to the store when you can make something now and do the job you are trying to do now.

So, with my breadboard setup, I am wanting to monitor the current demands of everything I am hanging off the one micro as it will eventually be running off solar and batteries and I need to make sure i have a few days of battery supply and enough solar to charge everything up within a days daylight. Don’t want my things turning off and losing precious data.

So i grabbed an Oled display i could not get working out of the box and got it chooching, a voltage and current sensor that i had doing nothing and made them all talk together with some software and she is skookum as frig. So all i gotta do now is wire it up with a nano stick it in a tiny box with some banana sockets and put it in between my power supply and my breadboard and I will always know how much current we are drawing.
