Battery to electrical?
Hi i was wondering about converting a lego motor which is battery powered into an outlet source on the wall. Any ideas on how to do this because i really dont want to rely on batterys. Is there any way to make a motor by myself which can connect into the outlet on the wall.
You will find out a lot about lego motors here

If you page down to the bottom you will see that another hobbyist has connected a power supply into a Lego system by constructing "dummy" batteries that connect to a power supply.
If you purchase a AC to DC wall adapter for this purpose make sure that it can handle the starting current of your motor. The link listed above gives stall currents for a variety of different Lego motors.
I'd go to www.digikey.com and look up
Wall & Desktop Transformers AC/DC (AC-DC) to get a suitable AC to dc converter.
The output from any of these converters should be safe (it will have an internal fuse). You may want to add an extrnal fuse with a lower rating that will blow first since the internal fuse is not accessable.
