Like many schools we have equipment that was bought, well used by a couple of teachers and then they left, the focus on the curriculum changed and the equipment began to languish unloved and gather dust in a corner. We have several sets of Amusement Park Lego Mindstorms For schools (RCX1.0 controller, set number 9725) that haven’t been out of the box in at least the last three years (though the dust on the top of the boxes suggested and the fact that the sets were first released in 1998 leads me to suspect it may have been much longer!).
As part of a CAS cross-curricular project to use Microbits with our year 4 children, we are building lunchbox buggies. We have some kit to build buggies but in an effort to give as many children as possible a hands-on experience, whilst not spending any money, I turned to our old Lego kits.
The Lego motors are more powerful than the hobby motors we used from our buggy kit, but I kept the power pack (4×1.5V AA batteries) and the motorboard the same and hoped for the best!
So we will be sacrificing a set of Lego connectors but gaining a new set of resources at no cost to make more buggies. This will also allow us to offer two different ways of building buggies. Whilst the Lego one is perhaps more familiar, building the frame will be more of a challenge than using the lunch box and there is more physical dexterity and care needed to attach the wires to the motors when not using the Lego connectors.
So if you have some old technical Lego gathering dust dig it out and give it a go!
