Diabolical Tests 5

Two very tough mind puzzlers involving tractor beams and lasers. Unfortunately, the antlines connecting buttons in the second test disappeared when I published, and I don't know how to recover them. Hopefully, this doesn't make things too unclear.

Particularly enjoyed the right side. Nice work.

Great test, challenging and well constructed. I think everything works like intended, excellent job. I played your "Diabolical Tests 4" last year and found a bunch of holes, that test needed more work. But this one is beautifully executed and a vast improvement. Thoroughly enjoyed and thumbed up. Thanks for creating.

Solution for the left side puzzle, part 1:
1 – Place two portals on the ground and jump down. While going up and down, place an exit portal on the next white floor surface, go through, and quickly place a new exit portal on the same floor. Repeat for the third white floor surface.
2 – Press the pedastool button and place an exit portal on the newly angled platform to enter Room I. Use the faith plate to jump to Room II.
3 – Press the pedastool button to retrieve the cube, and place it on the square button. Place 2 portals in Room II to activate the laser acceptor in Room I
4 – Jump to Room I, place a portal, retrieve the cube, and put on the button

Solution for the left side puzzle, part 2:
5 – Move the portal already in room I to the floor under the tractor beam and ride it to Room II. Reposition the tractor beam to bring you to the ceiling. Place an exit portal on the angled platform, and retrieve the second cube
6 – Re-activate the laser acceptor, jump to Room I, place a portal, walk to Room II, and put the second cube on the round button, reversing the tractor beam polarity
7 – Walk back to Room I, ride the tractor beam to the exit, press the pedastool button, and jump down into the middle
8 – Carefully place a portal on the far wall that brings you back to Room II (with the laser). Move the cube in Room II to the square button, and carefully place a portal that brings you back to the middle, as well as activate the central laser acceptor

Hints for the left side puzzle, if you’re confused:
1 – the laser acceptor turns off the emancipation fields between the two rooms
2 – when you ride the tractor beam up to the exit, you MUST have a portal in the room that emits the laser

Glad you guys enjoy my puzzle. I've decided to post solutions:
Solution for the right side puzzle:
1 – Use the fizzler button and two portals to bring the cube to the polarity button, reversing the tractor beam
2 – Step on the fizzler button, and use portals to have the tractor beam end on the wall button, at a slightly lower height
3 – Jump in the tractor beam and adjust the height to match the wall button
4 – Retrieve cube and put in tractor beam. Go below and turn on laser. Stand on platform and place a portal randomly
5 – Use similar tactics to steps 1-3 to properly place the laser
