Re: Pixy Camera

You do realize that this thread was necro'd from three years ago, I gope.... One day Zeros will be A35 based Aarch64 and the BCM2835's are freed up for this? I can dream :) You may or may not be correct about what the future of the Pi0/Pi0W is, but I think it's odds on that if the BCM2835 is replace...

Re: Industrial Environment Life Expectancy of Raspberry Pi 3 Model B and Raspberry 0 W Module.

Drying out of electrolytic capacitors gives you a defined lifetime for most modern electronics. I don't believe any of the RPI models have any (although your power supply may), so we go on to the lifetimes of all the other components, it's mostly passives and semiconductors. Modern passive parts an...

Re: Which Raspberry Pi Should I Buy

Pretty much the basic advice for buying your first Pi...get the current top model. At the moment, that is the Pi3B+. Once you're familiar with the Pi and have a project with special requirements, then--and only then--consider other models.

Re: Raspberry Pi 3 kills NETGEAR router

Since both web servers and ssh daemons are, essentially, passive in that they wait for inbound traffic and then respond. It's very difficult to see that the Pi could be doing anything to your router. I would start by closing the open ports and then changing the router password. The next thing I woul...

I could have stripped off the cron timing and stuck "sudo" in front of the command. it's simply an illustration that you don't need to put to value for the backlight in quotes. By adding the irrelevant cron thing you are more likely to confuse users. IMNSHO it would have better if you had not respo...

Sounds like you probably need to compile your own kernel...and as someone working at the graduate level, that should be pretty easy for you. (Given the nature of your project, I am presuming that it's a masters in Comp Sci or something very closely related.)
