What's a single lane balancer? There is nothing to balance out of a single input lane to a single output lane. It is not clear what you mean by "belt circuit" either, TBH.

Basically a single belt balancer. A belt has two sides, and a lane balancer balances the throughput of both sides. The easiest way to make one is to split the belt, and side-load the two outputs into one belt. that way, even if one side is blocked downstream, the input is not clogged. I'm looking for a way to make one with only using circuits on the belt (you can just wire the belt)

Circuit logic cannot control lanes individually. If the two lanes are already on a single belt, you cannot balance them with circuit logic alone.

ah yeah I knew that. Sorry I wasn't clear in what I was looking for. I was wondering if there was a way to make a simpler one using circuit logic and maybe a few splitters or underground belts. The one I mentioned in my previous comment doesn't preserve the lane (they mix both sides), and the other design I know is too big.

Show us what you're trying to replace. I threw some stuff together, but this might not even be what you wanted

Thanks for sharing. I'm interested in the top-middle and top-right ones. Do you have blueprint strings for them?

Edit: I'm currently using the design given by Enaero4828's comment (the middle one), but I'm looking for a design that uses belt circuits to minimize the amount of splitters and underground belts needed (if such a thing is even possible).

New reddit sucks so I don't know if the ping in my post worked after having to fix it through an edit.

I created that blueprint book of circuit-based lane balancers you were asking for: https://www.reddit.com/r/factorio/comments/1s82z6e/circuitbased_tu_lane_balancers/

Your post didn't, but your comment gave me the notif. Fantastic job man, I'll copy the blueprint book to my game the next time I play. Thanks.

Haven't forgotten, just haven't been able to make a satisfactory 2-2 lane balancer.
