Back in the 80's, in a time long before the DSi and PSP, gamers who wanted to entertain themselves while in the back of mum & dad's car were restricted to playing just one game! Yes, that's right - JUST ONE GAME!!! I know that may seem just completely outside the realms of sensibility, but it's true. And to prove it, here's one of those games...

This is my cat, he doesn't have a name :)
Vote for Cat on the Humane Society website! for the Spay Day 2010 Photo Competition.
Spay Day is The Humane Society of the United States' and Humane Society International's annual event to inspire people to save animals' lives by spaying or neutering pets and feral cats. Spay Day officially takes place on the last Tuesday of February—but events will be running all through the month! The 16th annual Spay Day will be Feb. 23, 2010. |

One of the blogs that I often visit is Dick's Rocket Dungeon and his New Years Day post featured a scan of if Worlds of Science Fiction magazine from x-ray delta one's Flickr photostream. I really loved that it looks both futuristic and time-worn at the same time.
And since I'm now the proud owner of RockSim 9, I thought I would see if I could make it fly (at least in the sim). And it seems as if it's nice and stable!

Built using an 18" length of BT50 body tube, paper laminated balsa fins and an 18mm motor mount, this should get to about 400' or so with a C6 motor.
The body and large fins are painted grey while the nose cone and small fins are painted black - the whole lot then got the dry-brush treatment with silver. |

Hacked Gadgets, Alan Parekh's blog, has featured my Camera Rocket. It must have been popular as the video received almost 1200 views in a single day :)

 As my last scratch-build of 2009, I thought it was time I would have a go at building a square rocket. So here I present Rocket Squared or Rocket2!
Built using a central core of BT50 body tube with four strips of balsa glued around the outside. The rocket stands 42cm (or 16½") tall and has a 18mm motor mount. I have no idea how to build this in Rocksim?!
 I spent some time trying to build a square nose cone but nothing looked quite right, so I sanded down the corners of the top-end of the airframe and stuck in a round one. Launch report to follow!
