Yes, it's that time of the year again -- time to give and get given.

What in the world of geekware out there takes your fancy this festive season and why?

me, I've ordered a couple of IP security cameras, so at least when my house gets broken into, there'll be footage to post on youtube...

Raspberry Pi and additional bits waiting for me under the tree - this time it'll be powered from a certified local USB PSU, and not allowed to connect to the Plasma TV. Don't want to blow a second one!! :roll:

Tell us more.... Mine's been hooked up to the TV for a couple of years now and is working perfectly - and it's an original unit with just 256MB of ram.

Nov 10 2014 the B+ raspberry Pi came to the public for sale.

It runs on much less power.

The power supply is 1 watt.

At 5 volts I=v/r

Current equals voltage over resistance.

Watts equals volts times amp (I*V)

The older Pi used 3 watts.

Does that mean my old RP is more powerful than your RP by a factor of three? :-D

Cheap usb wallwart shorted putting 240v over the 5v supply rail. This not only over-cooked the Pi, but sent the 240v surge down the HDMI cable into the back of the Plasma TV. The signal board didn't appreciate the tickle and a few components went pop. Surface components meant a board swap, which meant a 'repair package' module as the only option, and the cost of that was a few $$ more than a brand new TV.

Thankfully insurance (with the $excess) would cover it.

But at least the SD card survived after a re-format! :D
