how do u splice the wire?

@barda12345 You can use a wire splicing tool from HD or radioshack, or you can use a razor. The trick is to only cut the plastic that encases the actual wire.

@danbran67 I guess it could be a science experiment...

This exact ATO is still set up on the pico in the video. Works perfect. Why would I be kidding? Many people use this - I wasnt the first...
