Timbo's puzzle

Those were too easy.

Periodical IV (cababos):hugykob

Here is a solution to Periodical III (hivifig) - without cheating  : hyzypos

Still working on IV...

Here is a solution to Periodical III (hivifig) - without cheating  : hyzypos

Wow.  That compact double-speed dozer draw is really, really amazing.

[Rene]

Wow.  That compact double-speed dozer draw is really, really amazing.

Thanks. It was the first thing I started with: I had to have a way to pull the crates at double-speed, otherwise the solution would have been very difficult. And because a row of right-to-left dozer can draw at double speed, it was "just" a matter of getting them to loop back 

Here is a solution for Periodical IV (cabobos): memagis

For Periodical IV (cabobos): gecyvag.

I had the culling of the required crates done early on and just needed to get a dozer draw working that didn't take up too much space. I had experimented with this kind of draw before with two dozer streams reversing independently and rejoining with one coming up under a turn signal that the other was using, but it was just too tall. Reading the thread I knew Rene had come up with something compact, so I just stuck with it until I finally came upon the trick that allows extreme miniaturization (the stacked turn signals). Compared to Rene's hyzypos, the draws are almost exactly the same. I like the crate cull in hyzypos and memagis and the timing -- how it all just comes together at the end.

I had experimented with another dozer draw, but it doesn't save any vertical space so I rejected it. Here it is: digybad

I finally came upon the trick that allows extreme miniaturization (the stacked turn signals).

Not necessary.  cokihyk does the exact same thing without the lower of the two signals.

[jf]

Yes it looks like the top signal is the key. Here is a progression: tybubas, but I had something even a little taller. I had first joined the two streams on top, and then fixed it with the key piece. Now I see the streams don't even need to be joined. But once I had a shortened version working, I didn't spend much time optimizing.

I noticed I never posted my solution for Periodical IV.
Here it is: ciravuz
It is proof that you don't need a double-speed dozer draw.

NEW PUZZLE:
Sixteen rabagot

[Werbad]

For Sixteen (rabagot): dadakyc

[jnz]

For Sixteen (rabagot): bihedor (no downward copiers).  I had the most trouble with B

[Bucky]

Sixteen:   zexyses  C and E were the only ones that were even remotely difficult.  Pretty much everything else was copy-paste work.

[Dirdle]

Similar solution to Bucky's, only less tidy: folecun.

[immibis]

For Sixteen: bimoxix

[jnz]

Other solutions have inspired me to see if Sixteen could be done using the same "pattern" for each cell.
For Sixteen (rabagot): galorin

[immibis]

For Binary (metugeb): texeral

Edit: Whoops, I was looking at page 1. Ah well.
