DIY Any Arduino? Lets see em!

[orrganic]

ATM I have made.
pH meters.
Ppm meters.
Timers.
Fully automated reservoir systems: (550 liter)
With automated ph.up and down.
With automated nutes dosage that tracks the ppm and pH and adjust accordingly, up the feed ore delute. Dumps the Res,refill with water and nutes, Adjust pH. Etc..
Hooked up to SQL server. And a rpi. With vnc client for updates on the go.

ATM. My controller (at home).
pH. Automated up ore down.
Rh.temp 2 tents.
4 AC outlets 230volts:
2.ac out with timer for pumps.
2.ac out with timer for light.

All fully adjustable with menu system.
Can easily be configured to act. On rh ore temp to control humidity. heat..e.t.c.
Well you do all sorts of things with these arduinos and a couple of sensors.
And it's fun too.

Well I'm here to help.so any questions regarding arduinos and accessories.
Just send me pm.
Stay green.

Edit: ATM working on a 10v PWM.
For dimming 4 led drivers
With 2 PWM signals.
LCD display showing: power draw from wall.mah to led. And of course % of dimming.
Work in progress.

Wowzerr! Good stuff man. I've been thinking more and more recently about doing a timer for watering and a dimmer ore spectrum. Control setting for lights. I'll definitely be popping in with questions if needed

I’m surprised more Grow aren’t taking advantage of these capabilities. Of course some may think ya need to be able to fully program a computer in order to make anything useful, programming is one of those things that seem really scary and confusing

Well about the programming. A fully functional controller with menu and setting for everything. Can easily be 1500 to 2500 lines of code.
Wrong dosage of pH in hydro. Will kill plants.[emoji848]

A simple on off timer, maybe 10- 20 lines of code.

About the electrical stuff. A 24v solenoid valve connected to a relay shield with shitty wires. Can ore will burst into flames. Fry Io ports. E.t.c. EMF ain't your friend.

AC voltage can be deadly. So be careful.

Just my 2 cents.
Everything is possible with time and knowledge.
Stay green.

10v pwm led dimmer made with attiny85. working ish (freezes hangs).
attiny85 i2c and pwm do not work together(Google says).

Working on a new with ardunino nano, 2 pwm signals when finished.
Itś mostly a simple build for those messing around with diy cobs. And whould like to dim more than one led driver from a single knob.
Dim in %...watt from wall.. mah from driver to led

Its not far off .. look at dim % on the lcd. and the duty cycle on the scope

That's what's up!! Speaking of DIY cobs, You may be able to help me with this... I've got an Apollo 135W UFO that I'm considering converting to cob... It used two drivers to run the array of 3w Diodes. I'll try making a post about it today, ptherwise It'll be done tommorow morning. Mind if I tag you to get your 2cents?

Momma Saint's Birthday Present to me! I'm stoked, she probably wishes is was as easy as just getting legos like when I was a kid haha

Nice piece of kit.. enough to get started.you could call it Lego for grown ups [emoji3].we have a place for diy led building on the forum..
do-it-yourself-led-building is the place for blurble to cob conversion and bigsmo is the one to tag.Im not the one to talk to regarding cob conversion.
Stay green.

I made my temp/rh logger, and then some. Now instead of spitting out rh, temp and heat index, it spits out Temp, RH, and VPD! I have it set up to take readings every 30 seconds and write it to my sd card. You can graph the data in a few clicks with google sheets.
I’ll have some of these available for sale as a diy kit in the not-too-distant future, let me know if anyone is interested

ordered parts for the next one! I got a couple people interested already

Nice one
Be careful it can be as addictive as growing weed.[emoji23]
Keep it up.[emoji846]

New project new Arduino board.
But I also take old projects apart and reuse what I can. I have been "playing" around with this for years. Sold custom build systems and earned a "little" in the process[emoji6].
So I have all sorts of bits and Pieces at hand. I'm a programmer by education.and can also do electronic schematics. So combining these with growing, Was a now brainer.
If you want cheaper than arduino. Look at attiny. It's also an atmel mcu. But you need a arduino to program it.
I have books by the lots (pdf) if you need it.
Stay green.

Look at AliExpress for arduino stuff.

my grow is up stairs and i want to have a dht11 sensor wireless to give me data to my desktop downstairs or my phone. any ideas?
