SNIPE Posted June 23, 2014 Posted June 23, 2014 (edited) Hi I have just noted this part when wondering if it were possible that the motors could be driven by an ac/dc transformer. However the lego PF transformer has a normal power jack and not an PF jack on it so what is this used for? is there some way to change the jack on a suitable generic transformer so that its compatible with the motors side note = Could such a transformer charge the batteries in s PF battery box too? Having a transformer is way handier than having to mess with batteries especially for testing some mechanism where you don't need to have a wireless solution. Edited June 23, 2014 by SNIPE Quote
Kelkschiz Posted June 23, 2014 Posted June 23, 2014 (edited) Afaik that one is used to charge the battery of EV3 (45501) which is sold seperately and only usable with mindstorm not meant for PF. But i agree that is would be very nice to have something like you describe for PF. Edited June 23, 2014 by Kelkschiz Quote
Blakbird Posted June 23, 2014 Posted June 23, 2014 That part is used to charge the rechargeable battery. With the right connection adapter, there is no reason you couldn't use a DC transformer to power a motor directly. In a sense, this is all the 9V train regulator is doing (with the added capability to vary the voltage). If you got a nice big transformer (at least 1000mA), you could match the capability of a battery box indefinitely. Quote
dhc6twinotter Posted June 23, 2014 Posted June 23, 2014 I think Crowkillers uses a generic AC adapter spliced into a PF extension wire to power some of his static displays. Quote
