Here in the US, there is a hard push in marketing to buy heat pumps, heat pump water heaters, solar panels, house batteries, insulation and other ener...
Thought I'd update the project some. I thought something was wrong with my previous DIY PCB. I took the opportunity to add a on/off switch and do so...
Yeah, something died! I thought I'd have a full 24 hours worth of data to show today. First, a description of what I've learned and used. For home...
Zip files are also available on Github: But... there is nothing cosmic about a zip library. Both Arduino IDE (1.8.x and 2.x) simply unzip them in...
I'm starting to work on some of the logic and have watched the first charging cycle. To start off with, the Pb-Acid (PBA) battery was pretty much cha...
I had only built sub-assemblies on breadboards. For instance using on ADS1115 or just the relay circuit (resistor, NPN transistor, diode, relay), or ...
I simply can't imagine dealing with surface mount. I have a combined bench power supply, soldering gun, soldering blower thingy, but have never used ...
@byron, I always wonder, what if I could sell this or that? How much trouble would it be to get boards pretty much built. Like you mentioned, if I...
@byron Have you ever made one with surface mount components and have someone make the PCB and populate it? I have no idea if that is an easy thing...
I wouldn't know where to start trying to make a PCB for this. I didn't see a way to minimize wires crossing and so a multilayer board would be requir...
The fact that by convention, the powering + and - are not shown in schematics clears up the confusion of the parts. In the above image... you're tell...
To bring these two topic together, I ran your tests and have agreeable results - Am I being too optimistic to think that by using the Vref in this ...
