Spy Review

This video provides a clear guide in building your own stun gun. Its very simple too. Unlike commercial stun guns, the shock does not carry nearly as much venom.

And unlike some of the video guides this site has blogged about, this particular guide - making a home-made stun gun - is slightly different in that it is, in effect, a weapon, therefore, anyone making this should do so responsibly. Do not use it on yourself or others as it will give off quite an uncomfortable sting!

The audio socket does need to provide a power supply, but that’s very common for sound recorders these days.

Location trackers are getting frighteningly common now, and even I’m getting overwhelmed with how many different variations there are. The most useful type of tracker is one that allows you to remotely find out the location of the GPS device. For example, if you have a car with a GPS tracker fitted into it, and the car is stolen, you can find out where its located by sending it a text message. The pricing for such a bit of kit can vary, but often starts at the £200 ($400) mark for the entry-level kit.

If you fancied making your own remote GPS tracker for around £150, have a read of this Interfacing an AVR controller to a GPS Mobile Phone article on Tickerlog.
