When you are talking about a UltraFire 18650 5000mAh battery.
Yes, sold as a 5000mAh battery it’s really less than 1/5 of the advertised value, about 950mAh by my measurements. Beware what you buy. Stick to the well known names.

Just because I can.
100 is the average so that means 50% of people must be at 100 or below.
| IQ | Percentage of the population with this IQ | Interpretation |
|---|---|---|
| > 130 | 2.1 | Very gifted |
| 121-130 | 6.4 | Gifted |
| 111-120 | 15.7 | Above average intelligence |
| 90-110 | 51.6 | Average intelligence |
| 80-89 | 15.7 | Below average intelligence |

Looks like they are going to keep the current flag with the Union Jack on it.

Every wanted your technology to know you are in the house. I did so I could automatically turn off my motion sensing camera.
They email a picture of whatever trips them. Anyway when I’m in the house I’d rather they didn’t.
Ok, so using a nice new shiny Raspberry PI 3 with its built in bluetooth and a bit of python code later which scans for bluetooth IDs I can now do it.
So what happens is
Raspberry PI 3 scans every 15 seconds for bluetooth IDs that it knows. Works even if they are set to be only visible to paired devices.
If it spots a Bluetooth ID that it recognises it updates a mysql database status and logs the change.
The motion detecting cameras, thanks SB Components, now looks up that database and if any of the know IDs are marked as in then it doesn’t bother to take pictures.

First post.
I’m going to use this blog to keep track of some of my technical projects and perhaps a bit of politics.
This blog is actually hosted on a Raspberry PI 2 inside my firewall/router.
I Have DNS and DHCP running on another pair of Raspberry PI 2 and the fourth is used for controlling a few power points that control when the lights and CO2 go on and off on my nano fish tanks (no fish in the tanks just plants currently).
