Yeah, exactly.

So this was programmed in JavaScript, correct?

Cool, thanks!

To be clear, the Raspberry Pi is located at someone's house, correct, not in the box itself?I guess it gets info from the box over a LoRa gateway, and runs the web server physically from the house?

I don't think there are any dangers, but probably some disadvantages. I made a new one here: https://www.youtube.com/watch?v=BxwEkaiICWw and tried using phototransistors if you want to check it out.

Nice, thanks!

Nice, thanks!

Awesome, thanks!

Is this a working design? I don't see a video, and the non-rendered disks are missing magnets.

I don't suppose you have any video of this in action?

Should you be using a resistor with that bulb?

Ah, thanks!

So how does the onboard phone know what commands to send the Arduino? Is it just random, or are you somehow controlling that with another phone linked to it?

Thanks. So the controlling phone is linked to the onboard phone via Bluetooth, which in turn sends signals to the HC06? Or is the controlling phone sending signals to both the onboard phone and the HC06 directly over Bluetooth?

Thanks Becky!

Thanks!

Hi, NP. Needs to be a Trinket or other board that's HID capable. Arduino Pro Micro is one option, but not the Nano. Here's an updated version using a board called a Pico, which works in a similar manner to the Pro Micro: https://www.youtube.com/watch?v=ePKGLnjlXl4

Not right now, but will do another followup video or two with a bit more info.

Ah, cool, thanks!

Neat project. So the lights aren't conntrolled by the Arduino?

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!

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!
