Thunder & Solar Monitoring

I lost a voltage sensor the exact minute thunder struck very close to the house, Nicole happened to be filming because it was an impressive mix of rain, hail & thunder. Does thunder create some sort of EMP? Could be a coincidence but the timing is really suspicious. Sorry I mean sus.

dead sensor :\

Oh, well I’ll just buy a replacement.

And fuck, I forgot we screw over allies and suck up to dictators now. Phidgets come from Canada, I never found any comparable alternatives in the realm of current sensing that goes beyond small hobbyist projects. And I don’t really want to relearn/recode a whole new deal anyway. I just want replacement parts.

Extensive searching pointed to robotshop.com having Phidgets parts in stock. So I grabbed spares for everything to get a few thunderstrikes ahead and buy me a few years. For the top 3 parts, I grabbed everything they are left.

The battery voltage sensor is actually important these days as automation uses it to make decisions on which circuits to turn on/off. So for a few days until I got the part, I moved the panels’ voltage sensor to the battery. Sensing the panels is informational and has no real consequence on function. With anything solar, I have appreciated having spares at hand so it was time to spend some money and make that true for the monitoring side of things which we became more dependent on over time.

Built Me Another

I can make them pretty fast now, I bought top notch stepper drivers and servos for it. It’s so much quieter than the previous one. I’m learning that it makes no sense to buy cheap hardware when you’re not doing volume. The few bucks saved will be paid for many times over in wasted time. I took pictures for documentation but I’m not sure if I’ll have the time to sink into it.

A lot of refinements went into this one, from the thousands of hours that the previous model was in use.

This was the very first model, built long before I got into tabletop plotters:

It’s pretty pathetic to look at 🙂 but it was a good stepping stone. I built another other one for teaching based on cheap 28BYJ-48 steppers. All this to say Gondola PlottyBot v2 is very much the result of a journey.

Cool AI Use

Last time Esther wanted some coloring pages, I guess it’s time to battle with a bazillion sites trying to monetize everything. Jump through hoops here, web inspector there, the usual “this will take a minute” turns into another tech ordeal. Wait… I could just ask ChatGPT for some black and white stuff made for coloring.

The cool part? Esther gets a say into what she’d like to color. Well, she likes cats.

Then I realize that instead of asking for the generic stuff we’re used to seeing on coloring pages, we can ask for specific moments of her life.

Playing with an umbrella on a pile of woodchips? No problem:

Jumping on a trampoline full of Duplos? You got it!
And quite a few more:

Beyond the cool factor, I wonder if coloring her lived experience has a similar effect to journaling. Maybe, this helps process things?

More could be done to clean up the SVGs but this is quite sufficient for us. Evidently though, artists who were in the kid’s coloring niche have some competition :\.

One of the things that blows my mind with AI is all the things it can already do but have yet to be discovered.

All images above clickable for SVG, if you end up coloring one please send a pic 🙂
