Here's my sol to Trap: vagitod

[jf]

While working on Ternary Queries I came up with a switching device to direct dozers, and that lead to this new, compact puzzle: Pillbox tyxefov.

[Rene]

Very nice puzzle Pillbox tyxefov

Here is my solution:
cabacyb

[Rene]

And here is my solution to Trap (mogedug): rekirom

[jnz]

My solution for Pillbox (tyxefov): kozazep

Just finished my solution to cleanroom. gypecys

I really enjoyed the puzzle, very clever.
The left side was surprisingly easy, but I had some trouble with the right. I first tried to add up the numbers into a single barrel then choose a crate from the stream, but I realized that wouldn't work with 0. I then tried to retro fit my solution to add up 0, 1, 2, 4 and 8 crates but had some trouble with the dozers the way I was doing it. I finally discovered the simplicity of letting a falling dozer land on the doors from the keys to determine which numbers to add.

EDIT: Just saw jnz's solution. Wish I had thought to count down from F to get the final crate instead of counting up. I wouldn't have had to redo the right side to take care of the 0 case then.

I see three more cool solutions to Pillbox and Cleanroom. Rene's cabacyb uses the same idea to detect the value, but is much more finessed than my own now-seems-over-engineered solution zufolid. And I also used a falling dozer in Cleanroom to land on the doors to collect 1, 2, 4, and 8, but sluutthefeared's solution is so much more elegant. Very nice.

Also, I like the timing of the dozers in rekirom, and I'm still figuring out how kozazep works.

Edit: Ok, I see how kozazep works, and how cabacyb is so much simpler than zufolid. I had tried to throw off the timing at the start by using the ? barrel to begin in a random spot in the sequence, but only now do I see that the ? resolves to zero on the first addition, which was not the intention. But, the puzzle stands as-is and the solutions are excellent (and cabacyb is still much simpler, just look at the left side compared to zufolid). I've fixed the "bug" in Pillbox 2...

Ok, you've warmed up on Pillbox, so now it's time to work out Pillbox 2 lasegug. 

[Rene]

Thanks for the praise for cabacyb. I liked the solution as well. At the first try, I did not have the dozer cycle in sync with the time between '1's, and that gave all kinds of spurious errors on the right side. Syncing the dozer cycle with the '1's took some thinking, because of the odd number of cycles. The special handling of 0 is a bit of a hack, but I could not come up with something better.

Well, because I did not notice that the cycle starts at '0' for the original Pillbox, cabacyb does not rely on it, and also works for Pillbox 2. The counter takes two full cycles at the maximum to properly sync with the gate, and therefore can produce 2 incorrect crates (for 'F'). However, these crates drop away when the solution is pushed in.

[jf]

Yes I see that now. I handled the sync problem just by duplicating the machinery to match the timing, but your dozer matches it perfectly. And only now do I clearly see the flushing of the initial values -- very clever.

While working on Ternary Queries (still) I came up with an idea for a puzzle, and here it is: Insomnia bedebyc. Re: the name -- you've been warned. I have finished my solution, and now I can sleep!

[Rene]

Insomnia - As we are used from you, a very clever puzzle. Well done, JF!

Here is my solution for bedebyc: byrahov

[jf]

Rene, excellent solution! You've refined it to the minimal principle. I was so bent on finding a certain kind of solution that I didn't think of that which now is clear upon viewing byrahov. Here is my solution: movibir.

[jf]

sluutthefeared and Rene, could you please save your solutions gypecys and byrahov in the warehouse so they are not lost? Thx!

[jnz]

My cure for Insomnia (bedebyc): jagebor.
Rene's is much cleaner. 

Edit: whoops, accidentally cheated by using copiers.  Got to be more careful editing while in Sandbox mode.
Edit: dabohur should be according to the rules, but it is even uglier now.
