Raspberry pi 3

Thanks for that Theo.

When I came back earlier I tried Noobs on a range of the uSD cards I had to hand and eventually one seemed to work, downloaded and installed Raspbian.

WiFi worked OOTB and the whole thing feels very much more useable (as a GUI workstation) from the short tests I've done so far.

I just left it running an update.

I haven't looked at the specs of the cards I have but am waiting for a few 16G Class 10's as they were only a few pence more than class 4's (FWIMBW).

I may try a fresh OctoPrint image on the RPi3B later but if I can get the hang of running it from the CLI then I should be able to use the RPi1B I bought earlier.

Cheers, T i m

A little further back than I meant.

Broadcom originally built the Pi 1 chip for the 'phone market. It's got ARM cores, and a Broadcom GPU. (Videocore IV).

I read a while ago that they got into phones because of their very low power draw. Apparently the prototype arm core was running and they couldn't measure any input power - it turned out that the power lines weren't connected and the core was running on parasitic power.

I bought a couple from UK eBay seller margi17, they arrived yesterday and I've hooked one up to laptop via a 3.3V USB->RS232 dongle, a single AT command is all it took to connect it to my WiFi and get a DHCP address ... brilliant!

I'll be using this for the next step of my (glacially slow) smartmeter interfacing project.

I bought one of these

they are cheaper from china but I decided the wait was too long.

It should be here tomorrow.

Bollocks...

The last bit about the 8 V is right but rest is bollocks. The physical conn ection is two wire but doesn't use differential signalling that RS485 does. One wire is at a nominal +8 V relative to ground on the other wire. To sig nal a "mark" the + 8 V is shorted to ground via a transistor.

vBus is a protocol running over the physical link as described above.

There seems to be a lot of duff/dubious information out there...

Is Raspberry PI anything to do with Magnum PI?

We have Mini Magnums from time to time. Does that help?

Does it have a massive man-stache?
