I had one of those but I have some good news....they are no longer a blast from the past but are on sale in some of the 'bargain shops'. Saw them last week when I was shopping for cheap xmas presents before I go back to Thailand.
They are a brilliant and really simple way to get into electronics for kids.
Take it easy on yourself mate and get to Thailand.
Yay. those things are great. I think those sort of practicle educational toys should be used at school instead of battering kids with too much academia. But, for many schools, exams and league tables matter more than education.
Sure thing, I hope to get to Thailand, hope to see you there too. :D
