 Hi all. 
Originally I was going to send this link to 
David, ( thought your kids might use it) but others may 
benefit. 
Its an interactive educational program covering 
various subjects that you can download for home use 
for free. I got it for the electronics which I'm 
currently (pun) trying to learn.  
You build a circuit by clicking & dragging 
icons. You can drag various test equipment across the circuit 
to get readings & components blow up if you get 
it wrong. 
There is a digital section with loads of different 
integrated circuits to play with. 
The license needs renewing after a 
year.
