Likewise- I have a raspberry pi sitting in a drawer somewhere. Would be great if I could do something useful with it.
New Grower First ever grow, Northern Lights auto. Wish me luck!

@MoonUnit - if you’re feeling exceptionally bored, do you think you could post a thread about your raspberry pi set up? I’m sure other growers (like me lol) would love to put together a similar monitoring system

I would like to see it as well.

@Epicxr @Sleeper143 @unkn0wn Thanks.
Spider Farmer SF1000 Quantum Board
I tried to read/watch a lot of reviews on various lights myself before I chose it so looking to see how the SF QB goes myself.
I liked the convenience of 1 light for veg/bloom, the low profile with the lower wattage and potential long lifespan.
Height:
As height in my small space is at a premium, the low height of the SF QB was attractive and I can use for veg and bloom so don't need multiple lights. I have my carbon filter/inline duct fan inside at the very top which means the max height for the light is around 7" from the top of the 4' tent. If I moved them outside or to the bottom of the tent I could get down to within around 2-3" of the top, so great for smaller spaces.
The soil is around 8 1/2" from the bottom so gives me around 32.5 inches for growing minus the gap which SF recommends at 12-18" during bloom but I may have to push this. The heat doesn't feel bad with hands around 6" away at 100W draw so 'll find out along the way.
Output:
The documented 3'x3' veg spread (2'x2' bloom) of the SF1000 is also perfect and matches my small tent. At the lowest dimmed setting, it's fairly consistent @ 24" above soil at 10,500 lux edge to edge, it pulls around 30W currently.
I've seen online vids of the light goiing upto 130W draw but I'm hoping that at around 100-110W I'll get 32-35,000 lux albeit with slightly less spread at closer distances. Planning on upping power to around 20,000 lux once past seedling stage and then max once established in veg stage so I'll get a better idea of power and lux output then.
Heat:
Currently @ 30W draw, the QB is adding around 2-3°C to ambient temp with my inline fan dialled down to around 30%. With inline on full I can knock between 1 and 2°C off that. I'm choosing to run a 24hr cycle to keep the temps relatively stable and avoid the need for any additional heating. When output was @ 100W and fans on full, I was maintaining the 2-3°C bump over ambient. My dehumidifier which I'll need for flowering adds another 1°C to this so might think about adding an intake fan if temps are getting higher.
Worth nothing that the driver and heatsink on the SF get pretty hot so you can't put anything on them.

Raspberry Pi:
So currently running Raspbian GNU/Linux 10 (buster) on a Pi Model 3B with 1GB memory although it could probably run off Pi Zero WH ($16.58 USD). Any would do, as long as it has GPIO to connect the sensors and in my case, the camera connector.
Hooked upto this is a camera, a temp/humidity sensor and a capacitive moisture/temp sensor (all available via PiHut).
I think it's not polite to link in forum so I've included model no's etc for your googling pleasure
Humidity/Temp:
AM2302 (wired DHT22) temperature-humidity sensor [ADA393] - $17.85 USD
Connectors:
Adafruit Premium Female/Female Jumper Wires - 20 x 12" (300mm) [ADA1949] - $5.10 USD
Soil sensor:
Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor [ADA4026] - $9.56 USD
Connectors:
Adafruit JST PH 4-Pin to Female Socket Cable - I2C STEMMA Cable - 200mm [ADA3950] - $1.91 USD
Adafruit Premium Female/Male 'Extension' Jumper Wires - 20 x 12" [ADA1952] - $5.10 USD
[More to come on camera, wiring and programming, just writing it up
nice detailz

@archie gemmill thanks
all the 'tech' doesn't change the fact I've never grown a single gram and all ya really need is light, water and dirt.
Gotta earn ma stripes like everyone else.
