Spintronics Virtual Pack

OMG, as the title says I bought this for my 10 year old but kept it for myself. Don't worry, I will buy another one for my two kids after I finish the entire set myself. So much learning to be had in both circuit engineering and gear engineering. Quality parts (if you treat them with care) and spot on dimensions. Once you master part 1 and part 2 you can expand into other learning with your kids and make different apparatuses.The price point of both kits is well worth what you get. SOLID stem project.
