Electronics is one of my hobbys,and i wanted to know how they (Lego)
build there speed controller.
In fact,its a basic application of the LM317 regulator.
More info abouth the LM317 can be found in a data sheet book from
National Semiconductor (NS).
Note:There are also other providers of the LM317 (Thomson - ST).
If anyone is interested in the schematic,send me a mail,o.k.?
regards,
Ludo
