Cheap thrills

I have wanted one of these for an age, mostly for fun but also to teach simple programming to my children. Found it in a local charity shop complete and unmade. ..no instructions.  £2 you say?  SOLD!
Always up for a challenge, but equally happy to throw the whole lot in my greeblies box if it didn't work, you tube helped me out with the instructions and my archaic computer is the only thing that is still compatible with the software! Score one fully functional robot arm! !
