Hello
i have a VERY OLD meccano transformer/power supply from a hornby train set. It works and has a control knob to adjust the voltage. Has both AC/DC pins on.
This is the information it has printed on it:
220/250 volts 50/60 cycles 12 Watts
Alternative continuos ratings
A-12 volts D.C 8 watts
B-15 volts A.C 9 V.A
my problem is ... i have no way of keeping the voltage constant. So i was thinking of creating another circuit which i could connect to this one that had a regulator, which would need to be adjustable so i could have full control over the voltage and would need to range from 0 - 15v (DC only)
Another feature i would like to implement would be an LCD display or one of those LED displays to display the current voltage to a certain degree of accuray (poss 0.00) .
Will this be plausable if so what sort of circuits should i be searching for and also if someone could point me in the direction of some sites etc.
Thanks Alot - Kane
