Dope Tech Episode 2

<<@JM-ym8mm says : For anyone watching these days, make sure to get a capacitive moisture reader instead of the resistive one. The resistive sensor has exposed electrodes and measures the resistance between the two electrodes so as the soil becomes wet, the conductive layer will corrode as the wet soil reacts with the electrode. Capacitive ones are completely insulated from water and do not have the same issue.>> <<@roberthopgood1894 says : why not use noncorroding sensor?? is there sensor that indicates how much moisture - this would give control to plants that like drier soil this hat can control 3 pumps so what changes to monitor plants individually>> <<@tsrinivas2406 says : awesome !!!!!!>> <<@PauraviWagh says : Hi, this is an awesome video! thanks a lot. Can you suggest a camera in todays' time which probably is the best fro the above purpose?>> <<@windome4rle says : useless in a 20 liters pot>> <<@kylepearson8801 says : Would the 2 channel relay in the video description work with the valve you used in the video? I noticed the 2 channel relay is listed as 5V, while the valve and 3 channel relay used in the video are 12V. I'm not the best with voltage, watts, and amps, so I want to be cautious. Edit: Nevermind, just read about coil voltage and contact voltage being different things>> <<@JohnSmith-lv8xk says : How do you run the code headless ??>> <<@ThingsMadeOfOtherThings says : Instead of using a relay to turn the sensor on/off, couldn't you just power the sensor using a pin on the pi which you can pull high/low?>> <<@Badg0r says : Are you going to make more videos like this?>> <<@riotofone11 says : You're a legend>> <<@KyGBeats says : Hey! Love your video. Could i use a power from 230v in my socket with a 12vdc 1 a adapter for power supply>> <<@DragoniteSpam says : So I decided to take this a step farther and took the moisture sensor, a Raspi Pico, and rubberbanded it to a battery pack to make a handheld moisture tester. Good fun.>> <<@Fatpumpumlovah2 says : water level never dropped, sensor needs adjusting to be more sensative. i see root rott in your future.>> <<@SUPABROS says : you can also do t😊his with an arduino>> <<@bethmerino3516 says : Hello, good morning! I wanted to know where you connect the pins for the second and third code. I'm doing your project and I'm stuck there! I'm using a Raspberry pi 2. Your answer would be of great help to me. Thank you!>> <<@-.-4PR3ND1Z_R3L4X.-. says : This video is very inspiring. I hope YouTube recommends one with a fish tank. 😃>> <<@mihailvormittag6211 says : 👍>> <<@Not-THAT-ChrisPratt says : Outstanding! I am keen on plants and getting started in Raspberry Pi's and physical computing. These projects of yours are great! Thank you. Not sure if it had been mentioned yet, but if they remake the 1960's "Time Machine" movie again, they can get you to do the time-lapse of the plants in Wells' laboratory. (That is what your time-lapse movie reminded me of.)>> <<@mystery_1101 says : I love how he still checks the comments in a 2 year old video! :D>> <<@welshjohn6497 says : I am a little late getting to this project but plan to try it out, during the video you mention that the valve you initially used was best suited to a higher water pressure, di you ever try to identify a more appropriate valve for this system, that uses water fed from a holding vessel with minimum water pressure. I have now subscribed to your channel and will be a regular viewer>> <<@EngineerLewis says : There is a problem with resistive moisture sensors - they dissolve! The capacitive ones are much more resiliant and can even be isolated from the soil.>> <<@slobodanzemva3064 says : Thank you very much for the excellent video with simple explanations of a complex process. Did you apply the principle of Impressed Current Cathodic Protection to protect the moisture sensor, and used the a high-current driver IC in solenoid circuit?>> <<@Donnie3122 says : Great video, thanks for the run doen it was so easy to follow! Has anyone developed a way to send this to a server / dashboard for remote monitoring?>> <<@joelstitch says : How can I do this with multiple plants?>> <<@ЕвгенийИгоревичПотапов says : Достаточные пояснения. Можно попробовать собрать что-то похожее...>> <<@DobermannJeff says : 06:08 when ur gf comes over>> <<@eddie_Za says : Really nice video. Easy to understand code for newbie like me.>> <<@OsehShalomTV says : Amazing!!!!>> <<@TreBros says : Awesome! I really enjoy all of your videos! Keep up the good work "ExplainingComputers"!>> <<@jmgraydz says : you can actually run the sensor off of the pins because they generally use less then 20 ma>> <<@felicytatomaszewska says : Cutest teacher on youtube...>> <<@JamesMatthewHiggs says : Do you think this could be integrated into a pico, without a camera?>> <<@pluckydono says : I know some basic coding and, correct me if I'm wrong, there is no declaration of the time variable aside from calling the library. How does the python script know the difference between minutes and seconds for the interval and water variables? As far as I can tell the "while count_AA > (interval *2)" would also be in seconds as multiples of two.>> <<@JuliusDemeter-iu4dv says : Hi, Would this work the same way with Raspberry pi 4B? I'm new to raspberry pi and this seems like a fun project to try out :) Thank you>> <<@brendanquinn6894 says : You should play the saxaphone during the interval ! I know a bloke who can play the drums as well,>> <<@robertlock5501 says : 3:30 Baldrick: "I've got a cunning plan" 😂>> << says : Hello Chris. I love your vidéos and I am particularly interested in this one for teaching pourposes. But, as you said in other videos, the camera library for Python is outdated. Do you have a update on this Python program for bullseye? I'd appreciate that. Thanks.>> <<@jonathanlundberg1482 says : How long can those jumper wires be while still being effective? I'm planning out a few 4x8 raised garden beds, and I wanted to implement some automation in my watering/monitoring, but I'm not sure if I can mount the controller in the middle of one side of the box and reach out 4 ft in either direction for the moisture sensors.>> <<@batiandanielliu3598 says : Great video>> <<@mrmoderatormrbobmoderator69 says : Man, does this brother look like he knows what he's talking about!!>> <<@aaron6841 says : The only problem with this is most plants want to be just moist and hate drying out so this set up wont be a good long term solution>> <<@joelee24 says : Very nice and interesting video thanks for sharing ! I did similar thing with my DSLR shooting time lapse of plant grow with lights on, so that I will not have black images. I believe you can set up a light controlled by the spare channel of the power switch board to produce light that only turns on when shooting at night.>> <<@Josiahs3dPrinting says : Would this be the same if I use a raspberry pi pico?>> <<@Трезвыйвзгляд-у8т says : А почему не Ардуино? Ведь дешевле во много раз!>> <<@tim85a says : Just wondering if this would work on a raspberry Pico? If not I have a zero I could use.>> <<@marcsmithsonian9773 says : Now you cam cut it with mr scisors and put on butter roll.>> <<@cinquecento1985 says : Next: pi to feet cats and babies>> <<@XInfinity2024 says : This is super cool! I know people that have a hard time with remembering to water their house plants so I think this would be amazing. If you want to kick it up another notch you could also make it 100% solar powered. Maybe make a thing for this project that alerts the porson that the water is running low and to fill the container of water for the solenoid valve>> <<@karolmichalik9378 says : I saw once dude who did resistancy measuring and from that he extracted moisture as percentage. Quite useful if you have plants that require not just damp soil but more or less saturated. Sensor out of the box == 0 %, sensor in the glass full of water == 100%.>> <<@michaelboggs2969 says : Hi Chris thx for the Video 👍 Are you intrested in making a sun Tracker for a New project?
