Tis the season for questionable electrical contraptions.

Not only does it rectify AC into 120hz pulsed DC, but it also converts from 2 prong to 3 prong, because a lot of things that you want to plug into like timers etc are only 2 prong and you might need to plug an extension cord that is 3 prong.  So it fixes that issue too.

I'm sure we've all been guilty of jury rigging stuff for Christmas, feel free to share yours.

Not mine, but here's a fun one.
