Title:

Can I make MagSafe2 to MagSafe1 converter?

Text:

i know theres a $10 product that MagSafe1 to 2 converter, but now i need the other way converter.

(because all my work friends uses new MS2 gear, but i use older MS1 MBP.)

so anyway, i heard MS1's output voltage is ~16.4v(maybe max 18v?), but MS2 is ~20v.

i tried uses not-their-own power adapter of other things, 10~15% of over voltage is not a problem so far. but this time is over 20% difference. i'm not sure about working well this time too.

assume i can make magnet 5 pin connector thingy, could i use 20v pin to pin? should i use a regulator like 7818? or couple of diodes?
