Observation Nuc

[badger]

Hi, Does anyone know here I can get plans to make an observation Nuc ?
I would like to build one so I could take it to some schools to show what goes on inside.
Regards

question has been asked before, without result, if I remember correctly.
best advise is to either buy one from T8888nes, or borrow one, and copy it
