The LoneyBin 5.x

The run-off of my brain, in digital form.

Whole-house power consumption - Metrics Metrics Metrics. :-)

1.) If you want to get UART to RS-485 – Forget pi485. After way too long searching (but a nicely educational experience with pi485) I finally found some cheap import boards created to bridge UART -> RS485 that have:

They’re about $12 for 5 of them on amazon. You’ll need to add a few things (headers, etc.) or solder wires on by yourself, but it’s well worth the cost. The down-side is that they sanded the tops of the ICs. So I’m not sure what they’re using. :-(

2.) I’ve put together this simple circuit to create an appropriately sized burden to covert inexpensive current-output CT clamps to voltage-output, suitable to be fed to an ADC – either the 10bit built into an arduino, or another chip, like the ADS1115.

Using this, I’m passively monitoring the hot legs of my house and shop electrical feeds.

I’ve been working on metrics / monitoring / etc.

Notes on that:
