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?

I think you have this backwards: "If you turn your multi meter into continuity testing mode and put the probes on NO and common, it beeps. Means they are connected. when the signal triggers the relay, NC and Common terminal gets connected and thus switching occurs."NO == normally open, meaning not connected unless voltage is applied on the signal.

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

Your build popped up in my instructables newsletter. All the best with the contest!

Not trying to criticize in any way, just thinking it'd be fun to try with my current equipment :-)

Neat, thanks!

The nunchuck is a neat application, but is there any reason you couldn't use this concept with a normal mouse, or even a trackball?

I see you note: "To be able to control four motors I used two BTS7960B Motor Drivers (H-Bridges)." Aren't you controlling 6 motors?

Ah, OK, great!

Thanks!

Very neat. Yet another project to add to the back of my mind, ha!

Wow, nice work! I'd definitely love to see video of it in action.
