I was able to procure a Thai Stick - once! It cost me $10, which seemed ridiculous considering an entire lid was $10 at the time. See who remembers that term... LOL

1976 for me! Yep, the older bros and sis from our crowd were always ready and willing to help out a new fledgling stoner.

Wow o wow is right! What a blast from the past! We did this but used one of our album covers. I still have mine - Aerosmith - Toys In The Attic, and it still has the brown stain ring.

As a relative newbie on this site, thought it would be cool to share a bit of nostalgia. This was only my 2nd grow back in 1981. Some fun facts: ALL your equipment was DIY. This was a hydro system I built from an Igloo, a square mop bucket, an aquarium sump pump, and a bunch of hand-crushed...

Haha. Me too! Weird that I can recall computer programming languages and commands all day long, but never can remember mundane events like when I flipped a grow from veg to flower. I never thought to use a post/thread on this forum as a grow log, but I like it! Took a peek at yours and fondly...

Thanks! Since I sporadically ordered stuff online during the pandemic as my design went from napkin to reality, I would need to go back and tally everything up. My costs were higher than need be as I bought components I either ended up not using, or I destroyed inadvertently during prototyping...

What is that circuit board that looks hacked? The 817?

Love it! No apology needed, we're still talking about RPi and grow room automation. :D Now, I'm thinking there's a strong need to learn more about tasmota! Thanks, man!

Well, I hope my foray into trying these Kasa TP-Link Smart Plugs doesn't go south! But, I'm not using the their Wifi app, nor allowing the device to talk back to their "cloud" service. Maybe that'll save my butt. I found a link (can't seem to locate it now) that showed commands you can send to...

Yeah, I've used InfluxDB a little bit, but thought of it as too heavy for my use case. I stumbled on the QuestDB and giving it a serious look. If it doesn't play out well, then I may go back to Influx.

I'm with others here that acknowledge alcohol as one of the worst substances to combine with other substances. When I was much much younger, we had a saying: "Don't cut the grass after watering the lawn!" meaning DO NOT smoke a fattie after you're sauced on booze. Me, personally, I would just...

I have designed and built my own controller system that automatically logs anything and everything. But, like both you & @jondamon I'm finding out much of that data is no longer of interest. Before I trim back the logging, thought it would be interesting to gauge what others find useful.

Thanks for the compliment! Gen 1 - RPi 3B+ provides the top-level "brains" so to speak. One Arduino Mega for sensors and relay controls. Gen 2 - RPi 4 (4G) provides all the "brains". 1 Arduino Mega for relays & 1 Arduino Uno for sensors. Keeps the C++ code much simpler & cleaner this way.

I first started with RPi 3B+, but recently switched to a 4B (4G). BTW - Redis does run on 32-bit. Maybe it's because I opted to run it in a Docker container. In either case, 64bit on RPi4 provides the best performance given all the processes I'm running. I've also moved TSD out of Redis and into...

I'm prototyping Gen 2 of my controller design right now. Don't forget to factor waste into the final cost of your project! I've fried several Pis and butchered a few project boxes which meant replacements. I also needed double of everything so I could work out kinks & bugs on the bench while a...

I recently began pondering exactly what grow data is worth logging. I'm probably logging too much data that doesn't add value. Would love feedback from others on this forum.

@Lite Brite - That's very useful information. Thanks! My thought on the overkill mosfet is that I could drive other PWM devices that might require more current, all with one circuitry design. And, like you said - since they're cheap, it doesn't matter much. WRT the PI SD card failure... I...

Just sent you a txt msg from my mobile.

Not sure how you formed that conclusion. My first gen design uses an RPi 3B+ which worked great when I had much of the automation baked into the Arduino code. But my new design with the TP-Link module required that I pull all the device automation back into the Pi, which consumed enough...

I'm using the 5-30V; works great. I'm powering my Mega with the same 5 V source as I power the Pi. The Mega's PWM outputs can't handle the 10V nor the current used by the CL. You don't need any additional power source/converter to get the 10V source as it's already being provided by the CL...
