Cool, thanks!

How do you tell the time with two digits? Does it display hours then minutes?

Interesting, I'd never seen it done that way. I've definitely learned a lot of things later than I should have (including that trick). Thx for the vote, and glad it helped you!

NP. You could use a CNC knife setup too.

Nice device. I hope the letters you cut out on the laser weren't made with vinyl. Supposedly that can release poisonous gas.

Thanks!

NP! Been using that a lot - anything to save some soldering :-)

Nicely done. You can possibly use INPUT_PULLUP instead of an actual resistor for your button to keep things from floating.

Hi - Monoprice Select Mini V2. Link's in the article.

Interesting, thanks!

For the valve actuators and heaters, did you mean 24VDC? You have AC listed, which seems strange, but perhaps this is normal for pool systems?

Looks like the listing isn't active, but I believe it was 3mm Perspex off of eBay.Yes, it looks that way in person.

Hi Zephyr - thanks! No torque problems that I remember, but DC motors were a bit easier to control. This is the type of motor - I think it was 50 RPM, but I'm not sure TBH.

Very neat, thanks!

Looks nice, but you shouldn't cut vinyl on a laser cutter. Potentially releases toxic gas.

Good stuff. Got to love those Harbor freight boxes for component storage!

Thanks!

Hi, if you were to put some sort visible light filter on the LDRs or if there are LDRs made that only respond to certain wavelengths, I would think it would be possible. I haven't tried this though.

Thanks! 43" seems to work out quite nicely. From my limited research, it seems the desk height should be just a little lower than your elbows.

Neat. Thanks for checking it out.

Thanks! Quite pleased with the extra work surface so far.

Here's the ebay link: https://www.ebay.com/itm/391939159868 though pretty generic so most any would work.

Thanks!

Thanks?

Three LDRs in parallel were used here to allow more current to flow to each motor. You might check out the video for more of an explanation.It wouldn't work too well that way - would turn one way when light is in back and the other when light is in the front.

Thanks - I don't see why not.

Thanks!

Thanks!

Oh, ha, hadn't thought of that - thanks!

Thanks Carlos!

Thanks!

Thanks!

Thanks!

Thanks!

Hi, with this camera do you need some sort of IR illumination (LEDs etc.) to see the baby? I don't see it on the materials list, but perhaps it's assumed or there's enough ambient IR light for the sensor?

NP, easy mistake to make, as one would think of "open" like a door.
