Here is an how-to make an night vision setup with infrared for basically any application, in this instance it was used on a air rifle.
Note the ebay links are just so you get the idea of what to get
Things you need:
- Infrared laser module with adjustable lens (Over 200mw needed for brightness) Ebay link
- LCD screen + Infrared camera with interchangeable lens (lens required if used on rifle scope) CCTV site Link
- 16mm PCB lens (see above if required)
- Laser module driver, buy or build one. (will post below instructions to build your own) Ebay link
- Battery or power source. (I used rc plane battery) Ebay link
WARNING: High power lasers is very dangerous to your eyes, and safety goggles should be used at all times
- 6X 100OHM resistors
- 1X LM 2937 fixed voltage regulator (3.3v)
- 2X 16mF Capacitor
- Project board to solder on components
Here is the diagram
The camera can be used any way you want, or mounted on what ever for night vision, but for rifle scope application, it needs an 16mm lens, other wise you will see the inside of your scope, instead of the whole picture like you would looking down the scope normally.
Simply open up camera, and turn the lens out (requires some force, depends on camera I guess) and replace with new one.
Where to put it all
I used an enclosed plastic ABS container to house all the loose ends, wires, battery, driver , etc.
Note, I cannot add a picture of it in action due to high contrast on the camera, but here is one you can see something on the photo instead of just white.

Starting next year December, America won’t have to rush for their remotes to lower the volumes on their TV sets when advertisements starts.
When South Africa complained that DSTV’s adverts is way to loud, they responded by saying it’s aligned with International standards. I would like to see this ruling here to. Advertisments the same volume as regular scheduled programming. I find it pretty irritating that you have to reach for the remote and turn down the volume. (And no, it doesn’t make me pay more attention to the advert, It makes me change the channel.)
Holding thumbs and reaching for earplugs.

Well, this is funny, ironic and has made my day.
ANC spokesman Keith Khoza told News24 online that the changes to the webpage were not consistent with a civilised society.
“How does that assist any cause or anybody to tamper with information?” he asked.
Well, the answer is, how does passing the “secrecy bill” assist any cause or anybody except corrupt goverment officials? Isn’t freedom of speach what they “fought” for? Now they are taking it away from all the South Africans.
They are still stating there is freedom of speech but one has to follow other bills set out by them or only certain things is applicable.

I have found a great post Mr Zammler
So, I got myself a new Samsung Galaxy SII. It’s a great phone as it is, but of course after a while your hand scratches to *really* start using it. The first thing you must do is root your device. There are many guides out there on how to root it by using Odin (a Samsung application for flashing) but if you don’t have access to a Windows machine, your only chance is with Heimdall. As always, I’m not responsible for any damage. Use the following at your own risk!
As you may know, Heimdall is an application that tries to re-implement Odin’s functionallity for Linux/MacOS and Windows. First thing to do is download and compile it. Get Heimdall source from here: http://www.glassechidna.com.au/products/heimdall/. Try some binaries, if they don’t work, compile it. Check the package docs. Eventually you should have a ‘heimdall’ binary. The frontend is not needed at this point.
Find a kernel file that is suited to your stock kernel. Check this thread: http://forum.xda-developers.com/showthread.php?t=1103399. Make sure you download the correct kernel. Extract the archives twice, untill you have zImage.
Put your phone in download mode. Power off, then press Volume Down+Home Key+Power key. Keep them pressed untill you see an intro screen, then release and press Volume up. You should now see the “Downloading” mode. Connect the phone to the PC and check if it’s detected:
Then run (sudo is needed if you get a permission denied for the usb (libusb couldn’t open USB device /dev/bus/usb/001/010: Permission denied))
That’s it! The phone will reboot (notice the yellow triangle when booting), and voila. You should now have 2 extra apps, CWM and SuperUser. One last thing…
Backup your /efs folder. This is important, and can save you from an expensive trip to a Samsung Service Center. Checkhttp://forum.xda-developers.com/showthread.php?t=1068193 for more information.

Looking for a great video player on Android that plays almost all coded videos (mpg, avi, mkv m4v)? Try MX video player.
The player has easy controls, very quick, resource friendly and best of all, it’s free. No upgrade to pro-version nonsense.
You have simple slide controls on the sides and top and bottom of the screen to control brightness, volume, ect.
I found this to be my prefered video player on Android, just works great.
Now, just for uPnp integration.

Finding a good and cheap VOIP provider in South Africa can be difficult. Where to start?
First of, check out this page if you would like to know what VOIP is.
Most of the pages you probably already found on the internet sells VOIP in bulk and does not cater for home users or very small companies.You also may have found a few other companies which has dodgy names and you do no trust.
I would like to give you a bump in the right direction. The following 2 companies allows you to cancell at any moment, some give precredited airtime which allows for testing. Both are good and you have heard of before.
Visit the links for more info:
To start of with, check out this page to setup your home system wireless and cheap VOIP system.
