portal-2
I am in the 1970s facility right now right after you hear Cave Johnson talking about combustible lemons 😛 at the start of a chamber that looks like this:
So I started exploring and found out that I need to make it to this platform:
…to be able to make use of the steady stream of repulsion gel up there. Only problem is I can't seem to find a single way to get up there. I have tried again and again and again so if anyone knows how to do this please let me know! Thanks!
Hint: For the first cube, you don't use the faith plate (but it's target is helpful)
Answer:
You're half way there in your picture, just turn around and put the blue portal on the faith plate target, which will fling you up. Grab the cube, use it to shut down the funnel, then use the faith plate to fling you through where the funnel was and get the laser cube.
The Whole Shebang:
Here's right after your picture:
Then go place the cube to cut the laser beam and set up your second fling:
After using the faith plate to get to the prism cube, redirect it as shown to the other laser port
Go move the regular cube below the button, and go stand on the first lift. Change the portals (disconnect the laser) to make the first lift rise.
Move the laser cube with portals to reactivate the funnel, and channel it to the box below the button to lower the second lift
Then just cut that portal, allowing the cube to fall, and escape.
It's an SSTV signal, which turns into the following images when decoded.

I think the feeling of succes will be greater when you've solved it yourself. But that's just me. If you really want to know, watch this video:
