Re: [HOWTO] Rasberry Pi as a wired router with webmin as web ui.

Just in case someone stumbles upon this and needs it too. the dhcp3-server package has changed to isc-dhcp-server the bind9 package wants a sudo apt-get update before it works (at least on my RPi 3) with Jessie So the first command(s) in the OP would need to change to this to make it work these days...

Re: i2c repeated start transactions

Sorry to wake a sleeping thread, but I was wondering how I could take advantage of the 'repeated start' when I use python to control the i2c bus? My horizon ends where I'm calling on the io module/wrapper/library when it comes to this. Is there any method to do a write/read without the STOP via the ...

Re: RPi 3, Jessie, SDIO.dtbo, problems

One more question - do you think it possible to use Wifi and the 2nd SDIO interface interchangeably? Would it 'only' take a reboot for setting up the use of the other feature in some automatic way (software controlled)? So the Pi, before shutting down can decide with what it 'wakes up' the next time...

Re: RPi 3, Jessie, SDIO.dtbo, problems

The RPi is powered through a bench top power supply on pin 2 and 6 with 5V and uses about 360mA when running. I didn't check the value when the SD card is inserted, but the mas is about 3A, so I should be fine, no? Thanks for the list. to 1) I think the overlay does what it's supposed to do, output ...

Re: RPi 2B and A+ availability?

I haven't seen anyone try, but it may be possible to underclock and undervolt the 3B to get the same or better power usage as the 2B. If you experiment with this, it would be interesting to see the maximum power consumption measurements as well as efficiency in terms of flops per watt or mips per w...

Re: RPi 2B and A+ availability?

I'll see how I go, but I'm pretty sure the power draw for the 3B vs the 2B is up and not down/same.

Re: RPi 2B and A+ availability?

I ordered RPi3B and RPiA+ from RS Australia now.. that's should work for the time being.
Just didn't expect the RPi2B to be out of stock and having such a long delivery time, that's my problem.
At RS the RPi2B is scheduled to be back in stock in August.. that's 2 months.

What part of "it can never work" are you struggling with? Right - a bare bone RPi won't ever have WOL - I'm with you, no worries. I'm talking about a hat/addon/whatever that has got a power supply switch for the RPi on it. Something like this (this does PoE, not WOL): https://www.pi-supply.com/prod...

That adaptor (Microchip LAN9514) does have a WOL capability - however it is not enabled and as it is not connected to anything on the Pi, there is no point in enabling it.
I take it they aren't available on some headers, pads or pins either then?
