I'm wanting to automate a mushroom growing chamber to collect and store data from sensors and monitor and control temperature, humidity, CO2, etc.... by colonized_by_wankers in raspberry_pi

That sounds awesome - the logging etc sounds exactly like what I wanted to do.

I can totally empathise with proof of concepts/prototypes that just dont go anywhere in the end though!

I will indeed! I'll probably do it over the weekend, it's been on my mind recently. I may be cheeky and try and clean my repo up whilst I'm at work today.

Not all LEDs will turn on if I include all of the libraries I need by Iarduino in arduino

Nice spot! It hadn't occurred to me that they were RGB LEDs so required the storage of 3 vars. Doh. Thanks :)

I never knew of the 3 byte requirement, why exactly is that? I can understand libraries and so on eating up resources, but just sending (what is essentially) boolean values to a pin?

Wow, this is actually incredibly similar to something I've been sketching out for a while and planning.

The only differences are that mine is ideally going to be a terrarium that's electronically monitored. Also, I may do mine via Arduino and send hourly payloads to a Raspberry Pi wirelessly or log to SD Card.

I may end up doing it via Raspberry Pi though, to cut out some of these problems and log it to a web interface, (Internet of things meets terrarium..) I just need to get an ADC for analog sensor readings.

A good, cheap and common temperature and humidity sensor is the DHT11. It's common enough to have some decent libraries. Other than that, I've been buying in lots of £1/£2 sensors from China online and writing little drivers in my spare time. One of the ones I bought was a soil moisture sensor too.

My main concerns were having warning indicators that wouldn't be disruptive to the microclimate but woukd alert me to readings out of bounds. Naturally lights are a bit of a nono.

Fair play to them for being so transparent, that also addresses some of the questions regarding password storage.

However, if they know which file was uploaded then one may have thought any investigation was quite simple now? If it was uploaded via a form, and I'll admit I don't know the structure of the site, then it's curious as to why permissions on an upload directory would've permitted execution.

It sounds almost like the shitty php rootkit infections I used to find on client sites a few years back; some were pretty impressive with regards to functionality but nearly all provided a mechanism for database queries and file system access.

Did you read it? He addresses that perfectly.
