I discovered these really awesome IR sensors that you screw into an existing light socket and it turns on when it detects movement. I've added them to all my hallway lights so you don't have to turn on or off any lights when you go through the hall way.

They look good, I don't suppose you've seen one that has the bayonet connectors? I know you can get adaptors but that'd be getting to be a bit too much on that thing.

I havent, but if you search B22 (bayonet) sensor, there are a whole bunch of led lightbulbs that have the sensor intergrated.

Also I forgot to mention, most of the B22 and E27 fittings and adapters on Aliexpress use plastic sockets, so you can only use LEDs otherwise the plastic gets melted.

Thanks @Will.

Just ordered one of these Motion-Sensor-LED-Bulb-B22-5W to see what they're like.

For those wanting to control 220V via WiFi have a look at these babies (I have 5 at home, soon in use):

But please don't switch 10A with it! Maybe some lights or similar stuff.

Cheers Oliver

I'm ordering some of these Orange PI to add to the pile of single board computers I mean to do something with at some stage.

Orange PI

What does "Compatible with RPi2" mean? Can a SD card setup for a RPi2 be plugged into this and it will all just work?

You have to use their software image on the more expensive ones so I assume that is the same on that, its just that it has a header that is somewhat compatible I think.

I thought if anyone would know they'd be on this thread -

I don't like how my Oral-B electric toothbrush heads feel too soft AND barely lasts AND are very expensive.

Any polishing grade alternatives or at least cheaper stock to find anywhere on the net?

USB micro cables that go both ways for plugging in without looking easier. -

On spec, I got one of these... (redirects to the same place as the above link). It arrived today, and doesn't work at all.

Weird, I have 8 of the microusb ones and they all work great. 1.4A charge thru them ok.

No apple ones because I have nothing to connect those to.

@joker97 I tried the Chinese knockoffs, and they are bad. Try the genuine Floss action brushheads. They feel harder and last a lot longer. I tried to get some cheap genuine ones off eBay a while back, but the trader was a scammer and only pretended to send them, requested and got a refund, but I had to stick to my guns after they tried to trick me into giving good feedback first!
