Welcome to Pathfinders
Design + Technology

Welcome to our website!

Our kits – designed by Derek Wulff – are made of natural, untreated wood, from Forest Stewardship Council (fsc) wood. We like to make innovative products that take time to make, work well, and look cool on the shelf. Yes, they are challenging, but without a challenge, where’s the fun?

We hope you enjoy the kits we have to offer and welcome any questions you may have about them, or suggestions for new ones. (Our Leonardo da Vinci line of kits was in response to a request from the National Gallery in London, England, and our Robotic Arm design was in response to a suggestion at a Science Venture camp meeting at the University of Victoria!)

Enjoy our site, and let us know what you think!

Our Newest Kits!

A new addition to the Ancient Siege Engines Line – a Battering Ram!


A battering was was a formidible weapon, used to knock down walls and splinter the gates of fortresses, castles and villages throughout the Middle East for over 1000 years. Originally invented by the ancient Assyrians around 900 years BCE, it was widely used by the Greeks and Romans durigng sieges from Ancient to Medieval Times.
This new kit makes an authentic Battering Ram – so you can lay siege to small castles around the house, and remind you of a day when you could strike fear into the heart of entire villages with a swinging log in a moving house!
Like all of our kits it is made of natural wood and plywood from sustainable sources, and the pieces are pegged – which is really fun (when you make one – you’ll see!)
This rounds out our Ancient Siege Engine Line with a great looking robust kit that will look great and really works!

Our next kit will be here in a few months – A super cool STEM Hydraulics Mini Maker Set!


Sky Surfer – finally here


Pathfinders, the world leaders in not-so-random hurling devices, has launched its latest kit – the over the top (of the shelf) Sky Surfer Airplane Launcher.
A fun building kit and then you are off to launch airplanes of all types! Included is paper and card stock, and some clay for balancing your new plane designs. There is also a detailed booklet about plane designs, aerodynamic theories, and the history of paper airplane (which you may find surprising!).
The worlds coolest airplane launcher, tested in science centers across this nation and with kids of all ages – has arrived! 
Great indoors or outside, this kit will launch planes from 10 to 50 feet – and more (especially if you are standing near a cliff, and the plane goes over…)
Make your STEM aerodynamics programs super cool and interesting with this easy to use launcher that makes science even more fun!
