It's not railing over the idea that automated testing being the next big thing. It's that this is not it. there's nothing cutting edge or new with it, it's bigger and maybe quieter, which drive technology has been out for years to make motors quieter.
There's nothing in there that a person in a garage can't create, someone with ardiuno or raspberry pi experience can easily write software for... and I'd venture to say for far less than $3k.
as i read before its for fish store that can also test customers tank water they get sample for you and it can test it
also if you have time yes you can do it there is some ppl did it on youtube for fun
i am an expert in Arduino and Raspberry pi
i can do any thing with them i printed and did a full humanoid robot with VR
this reefbot i can do it easily same idea
but i don't have time to mintaine it and update it every time so i bought it and insted i gave them some idea that they can implment to devolpe it and in the end i will be the one who Benefit from it
same came to apex
its conttroline your system
with Raspberry pi you can do same idea
and you will find a big thread about reefpi
but still ppl buying apex
