Never messed with arduinos specifically, but I've built a few projects throught the years with ESPs, those things are dirt cheap and very fun to work with! Nothing with motors though - mostly attaching them to sensors and batteries to collect data, or control lighting (LED/RGB strips, etc).

There's just *way * too many interesting things in the world, and so little free time! It's a tragedy really... :)

Hope you can find the time and life conditions to embrace the projects you love. Have a great day!

    Damn that's brutal...

    I've jumped out of ladders as I've felt them starting to fall a couple of times, never more than like 2 metres high though, and it's scary.

    I wouldn't climb anything higher without strapping my self up to something, it's just asking for a quick grave...

    You're doing it wrong brother, if you're doing it IRL that's work, good riddance...

    But for real, that's really cool! You hooked up a motor and photo resistors to a controller you've programmed? Bonkers. Do you have any write up about it? super curious about how you did it.

    Could you live without learning a made-up assembly-like programing language just so you can have your solar panels track the sun, only to find out you know very little about "azimuth" and "elevation" and now your potatoes aren't growing because you can't power that grow light.

    I mean, you could, but are you even living at that point?

    Did you mention how fun it is to find out you got your gaseous fuel stoichiometry wrong? It's a blast.

    Oh. Good point.

    Unrelated, but anyone deep enough in the comments to read this, you might consider checking out the game Stationeers - a brutally complex base/space station/colony building game that will eat years of your life if you let it, stay away. Huge fun.

    Alternatively, big players can take note that poking the orange pig around a bit and wait for the lawsuit so they get judicially mandated access to a bunch of information trump would fight tooth and nail to hide is a possible strategy.

    Just saw the post about Helsinki opening several bridges for a similar purpose, so thought I'd share this here as well.

    Porto Metro system didn't exist until around 20 years ago. Just last year, it carried more than 90 million people, and it's not stopping.

    While traffic in Porto has actually gotten worse, as tourism and building rehabilitation have exploded, the investment in the metro continues.

    This bridge is part of the new "Ruby line", and will provide another much needed way of crossing the Douro river, and will be exclusively used by pedestrians and cyclists, along with the metro.

    This line is great because it will connect the other existing lines to a university campus and a large shopping center, while serving a fairly high density area where the residents mostly work in Porto, and have to commute daily.

     

    Hi everyone!

    I'm trying to control a "dumb" led light strip segment with an ESP-01S. This is fairly low current, the strip will pull 150mA-200mA max (depends on... artistic? needs).

    I have two NPN transistors (2N2222), one to control the 12V supply to the white "channel" and the other the red+blue (don't need the green).

    I had to pull-down the gates as I had some flickering, and it works perfectly if I manually connect the GPIOs after the ESP-01S boots.

    The ESP will boot if I have the RX pin (GPIO03) pulled down on boot, but not if I pull down any of the others.

    I'm not smart enough to come up with a way to have that extra pin I need to be high only during boot, while the gate it's attached to needs to be pulled down...

    Any thought, other than getting something with more IO pins?
