Re: Object Detection

I suppose it depends on the crack sizes, small ones will be hard to detect unless high res image data is used. Most AI vision stuff in real time is around 300x300 pixels. Could a florescence spray help, it would tend to collect in the cracks and shows up under UV LED spotlights. Very easy to detect ...

Re: Barebox

Thanks guys, interesting links. Barebox is a mix of boot loader and Linux I like the options of choosing OS's. With the network stuff, picking and loading the OS from a server?

AT(ISA) bus? That looks pretty much like the GPIO header when SMI mode is selected. A 8, 9, 16, 18bit bus can be used.

Re: General language discussion.

Re: A Pi Pie Chart

Wow, the Core Duo's are only just over 10 years old, I thought they were ancient ;)
My Core Duo only seems about twice as fast as my Pi3B+but i have not bench-marked it enough.

Re: Should the Pi Forum switch to Discourse?

Perhaps start afresh with the Pi4 at the latest and just get on with it from there. That might be a good idea, keep the existing system for Zero to 3's. Have a new one for Pi4. How much different will the 4 be? The volume of users for the Pi4 maybe much more 100 million users :o And if it is Deskto...

I have been powering Pi's from the headers since they came out.
Mostly in embedded applications where I design the power supplies too.
Er, GPIO pins stop working if you put 12V on them :oops:
