Hey guys, just a heads-up that the version of the PCB shown in the video is the most recent iteration and I have not yet had the chance to build one with the handful of changes made (swapped a couple pins around, changed some text, modified a copper pour). Changes were pretty minor so I don't expect any issues but you never know. I have a handful on the way and will build one when I get them.
how is it going?
looks very exciting
Dear LED gardener. Will you ever come back again? Or is you channel cancelled for good?
Damn dude, you have come so far in just a few years. From messing around with some diy led lights to all this automation, very impressive.
This guy right here is probably the first person to ever comment on something I've created. Like 6 years ago. Absolute OG. You still growing? I remember the crazy tomatoes with thousands of flowers.
Just here 2 years after the fact to say that your videos are better than the ones you suggest lol.
Sad to see the website and forum go, thanks for the info over all the years, truly appreciated.
Good job brother! Great first go at a PCB. If I could offer one piece of advice (one that took me a few PCBs to really appreciate) it would be to future proof your boards. Three tips:
- use solderable bridges (essentially open switches you can close and open using a bit of solder. If you are unsure whether you’ll actually use a circuit loop place a solder bridges before hand to completely cut it out of your active circuit. You can find these bridges easily in the parts search
- run unused GPIO pins to an open area on the board and route them into a header grid. It doesn’t cost you anything and if you decide you want to add another sensor all you need to do is solder on some header pins and using some jumpers you can diy a solution until you accumulated enough reasons to design mark 2. I also recommend running i2c, UART, SPI and some grounds and VCCs. Sounds like a lot but it’s actually very easy to achieve and costs you nothing extra.
- use pads to trouble shoot and validate circuit. Add some pads to your circuit before or after major junctions. Instead of soldering wires on them, use them as test points for your multimeter probes. Have a test pad atleast gnd and vcc.
Great advice, thanks for the tips!
Initially I got into Docker and Home assistant because I was looking to control my Zigbee and WiFi enabled lights and sockets. But I’ve just recently realized the potential of ESP32 and using MQTT to build my own automation setups. Home assistant is incredibly conventient and powerful to interface with my projects, but I’m looking forward to designing custom PCBs to make my controllers more compact and reliable. Nice work either way!
It is very interesting! We are waiting for the continuation.
Thanks for taking the time to break down your setup in understandable sections. Admire your approach to automation, and pretty soon you will have robots tending your downstairs grow room. Maybe not, but amazing tech for sure.
Awesome video and an excellent result for being unfamiliar with PCB design/build.
Pretty cool man, kudos to you. Thanks for sharing!
You can try setting the clock frequency lower on the I2C bus if you're running longer length cables on those bme280s
Awesome work here!!
Lovely job buddy 👍
Cool stuff man
Very nice, respect !
Neat, I want to build a similar system for hydroponics.
Great job bro! I'll send you my final project by e-mail when its done :P And thanks again for the codes to calibrate probes through home assistant! 🙏🏼
That’s where I am stuck now? Is this done thru template’s?mqtt?
You should considering selling these builds with 3D printed boxes all wired and USB with R Pi configured !
had the same taught
Thanks for this video, its really motivates me to streamline my system! Your older videos were a huge source of knowledge and inspiration to me when I set up my first HA automated grow tent. Just wondering, would you consider doing a video on controlling your AC infinity exhaust fan via PWM? I’ve set up PWM dimming for my LEDs with an ESP32, but have been a bit nervous about modifying my fan’s control box. Cheers!
that's amazing work i could really use your help with a similar but a little bigger project
Thanks!
Hey, awesome! Thanks a lot, Mark! How's your build coming along?
And now quietness? Come on.. You have done some really great shows.. Keep going...
This is so awesome I’ll get to this level someday but I guess I really need to start the a system first lol
Ah yeah, you've just got to get it started and get a little momentum.
@@LEDGardener true so I start my first DWC setup last night
Way to go!
Got me jonesing to make my own PCBS…. Need to finish several half finished projects first!
On a side note, I’ve started designing and printing board/component mounts for DIN rails. I like the modularity and ability to make a cleaner package.
Nice. I like DIN rail stuff too. The mean well DIN power supplies look nice and clean.
@@LEDGardener 👍 I got a DC/DC Meanwell for the pi plates project 12v to 5v so it’s easier to use with solar.
Enjoying your videos. I’m new at hydroponics. I have a greenhouse in South Carolina which means I don’t really have to worry about lighting, humidity, etc. I do, however, like the idea of automating two reservoirs, ec & ph only (I use a two part nutrient solution). Your thoughts on the simplest way to go? Thanks in advance!
hello, anyone continuing in this great work ? or any discord group ? reddit group ? anything ..... copying this masterwork for some time, i got almost whole hardware side done .... software side will be a whole other story.
Thanks for the PCB tutorial. But the ultrasonic sensors dont work well in reservoirs. I tried. Condensation will destroy it pretty quickly. The waterproof version jsn-sr04t can work well but need modification. It still has problems caused by condensation if you just slap it on top. If your reservoir isn’t a 55 gal drum I’d recommend using automotive fuel tank parts or e-tape (both basically a varying resistor).
I like the micro controller approach. I binge watched all your home assistant related videos. I am curious though. You no longer use the dosing controls to automate the reservoir nutrient levels? Was there any issues with the way you had your nutrient doser set up? I was considering doing the same thing using peristaltic pumps. My current automation is basic and provided by a click plc. I just have lights and pumps controls automated. But sensors for plc are pretty expensive so I am looking at this project. I love how you stepped up to a customized pcb.
id like to have a 7-10inch touch screen to monitor the stats right at the box and be able to turn misting systems on and off as well as ultrasonic foggers,
For measuring the water level, you feel non waterproof ultrasonic sensors are fine?
What are you using to do the actually nutrient dosing are you using your previous nutrient dosing system.
Any reason why you did not include more dosing pumps for the nutrition?
Do you have a forum or maybe know of a forum that talk about mods for grow tents electronics? Thanks
cool - Do you make them for others?
Trying to find link to support channel and send some love but I cannot find it. In my youtube studio, when I look in studio it only mentions earning money, not giving to a channel. Any help here?
please come back sir
Impressive! What is your background as for education? Or did you learn on your own all this?
Can i use 30pin instead 38pin? What is the difference between them?
Could you share your new configuration files, specially for esphome? I have done a similar configuration on my own and met a lot trouble with proper communication with Arduino controller.
is it also possible with sanlight evo light ?
Does the micro controller clip get hot?
anything you think you would have done differently now that it's been 6mo?
Great video and thank you!!! Any plans sharing some of the esp32 code? I'm currently using Mycodo for a similar project and would love to have more control over my AC Infinity fans.
The ESP code is just YAML done in ESPhome through Home Assistant
@@LEDGardener Thank you. I've watching more of your videos and learning a ton :)
@@LEDGardener Anyway you can share the calibration(ph) piece?I know in the past you were using a uno, but how is it being done now?
@@jahmesiahkeys9597 email me at ledgardener(at)gmail and I’ll send you code and instructions
i would love if u actually sold the working pcb with all the parts man id buy one off u in a second just dont got the time to do it myself this thing would be perfect for my diy cob /samsung quantum boards 4x4 tent grow lol just make ppl sign a use at your own risk liability waiver before they buy it haha i am using all meanwell hlg-240h-c1400b and hlg-240h-c1750bdrivers
Hi How can I configure the L298N Dual Stepper Motor Driver Board Module to work with a esp32 and esphome? to ensure I give just the right amount of ml to my plants?
Prime your pump, run for 20 seconds and measure the amount dispensed, adjust the speed until 20 seconds = 20 ml's
This is great. I thought you will embed the dousing system in this system. Are you going to do it in a separate PCB or tutorial?
I have dosing stuff on a separate PCB - will check it out in another video.
@@LEDGardener No knowledge about electronics. Is it possible to combine the dousing system in this PCB?
If you mounted the motor driver boards somewhere else, you could put a header on this PCB and assign some pins to the additional pumps. You might run out of pins though because each pump needs a pin for enable and a pin for pwm (so you can tell the pump when to turn on and how fast to go)
@@LEDGardener You can expand the number of I/O's using an MCP23017.
For sure - I just meant with the current layout of the PCB.
Edit: I guess I had mentioned adding a header so my response doesn't really make sense. Thanks for the part number.
Hi All,
I am very new to Hydroponic control. I am hobbiest and good in electronics and robotics but never made a hudroponic system. there are so many and i am confused.
Can someone help me to suggest a link where i can build a complete wifi system?
Really appreciate, it will save a lot of time,
Thank you so much
Hi everyone, just wondering if people have seen the new telos mesh bluetooth driver and if anyone knows if it would be possible to wire this up to any grow light of suitable forward voltage overall size. Its a 320w Inventronics driver. If anybody is familiar or has any advisory info it'd be very useful. Cheers all.
hello, can you please test the chinese knockoff quantum boards? Especially the Lm281B+ QB288 for 25dollar is very common.
have you setup a discord server or room on matrix for niche discussions?
If anyone is interested I plan on ordering some boards based on his with a few modifications if anyone is interested it might be cheaper if we make one big order. I shared my easyeda project. Just search for auto gardener.
Hello, just wondering if you may be kind enough to share your updated plans? I'm just looking into this now, and I'd like to see how other people have decided to modify this further.
Can't I just buy 2 finished board directly from you?
Do you sell these ?
Don’t run tracks or ground planes underneath your Esp32 antenna.
Noted - thank you. Even if the ESP32 is on headers?
@@LEDGardener Yep. Try to give the antenna as much space as you can. A slab of copper pour will absorb all your lovely wifi before it reaches the antenna. In your case it’s not really a problem if the Esp32 is mounted flat as there probably aren’t many radio waves coming straight out of the ground. If it’s mounted vertically it could create a blind spot though.
did something happen?
I'm wondering the same thing.
this fine gentleman said he have some more pressing things to do, and since then no other videos :( @@kevincarroll2220
Did anybody ever find out?
