Lets share pics of lifters!
This is my latest build, I'll go through how to get into making lifters in this thread and hopefully we can get some actual hovering going. The main thing to note is that the lifter itself is actually easy to build. The main challenge is getting the high voltage power to run through it to get it to work. We'll experiment and discuss some do's and don'ts in this thread.

I started this project off with a sheet of cardboard. The cardboard itself is actually not necessary but I decided to make it with cardboard to support the foil as an experiment.

I divided the cardboard into three sections to make the sides of the lifter. The cardboard is lightweight but still rigid and sturdy enough to provide support for the airfoil.

The lifter is sometimes called airfoil because most of it is some type of foil which acts as a part of the propelling mechanism. You can use any foil you like if you're interested in following up with this experiment, just make sure its conductive and lightweight. I mainly use variants of aluminium.

The lifter needs supports which provide a gap of about 1 and a half inch or 3 cm between the foil and the wire above it. They should be lightweight for this experiment, drinking straws should work. The foil itself is somewhat elevated off the ground by these supports, which is a good idea since it will ideally be conducting a somewhat through-reaching high voltage.

Attach the foil to the support. I used tape, but you can use other ways to attach it. For this lifter it's preferable to keep it light-weight.

Okay so the op build was a fun experiment but it might not work as a functional model.
I did a lot more reading on airfoil lifters. It is preferable to keep the larger surface
cathode smooth and rounded on the end facing the anode wire. But on the end
facing down its more beneficial to have that side sharp as it causes an ionic corona.

I've been experimenting with some high voltage supplies but they didn't produce high enough voltage
to power the lifter as of yet. 1 mm visible spark means 1000 volts. So far I've been able to get up
to 1 cm long visible spark but I need to make a voltage multiplier circuit to increase that
to get at least 1,5 cm one out of it.

I noticed hackaday had a recent article featuring lifters so I'm linking that here;

Scratch that, it needs a better driver. After reading more high voltage articles it also makes sense to insulate the power supply better, maybe with mineral oil. The voltage multiplier could still work but the output from the flyback could be much better than what I've got so far.

The effect might work better without an ionic corona, that's one of the things I'd like to experiment with
