After the major success of the sentry gun build at a local event I have decided to go one step further and build two more. The next two will be replica sentry guns from the film Aliens and ofcourse will be fully functional water pistols as the one above.

  2. If you have a look at Zoe's blog, http://podpadstudior9.blogspot.com you can se I have just completed a mini version for her and added a few more detailed photos. This one is made from old parts that I had lying around in the garage. The power is an old cordless drill, the barrel MDF and dowel, car windscreen waster pump, old water bottle, old camera tripod. The LED strips cost about £3 each. The gun is powered from a single 22Amp SLA battery in the case, which used to be an old cordless drill case, now painted up. It is all very simple really. The electrics inside are very simple, just a single relay linked to the cordless drill. The coiled wire is patched up to a home made switch which in turn runs down into the battery box. Once power is applied the drill spins, water pump sucks up water from the water bottle and LED's glow. I am just about to fit a simple motor system to this gun to allow it to track left and right via a movement sensor, should give it a bit more realism. Hope that helps.
