Hello everyone! - It's Christmas break!

I don't know if I will finish this in the couple weeks I have, but in tribute to the forum and you guys, here is what I have been working on!

I don't have any plans for my elements yet, so any suggestions are welcome!

Everyone have a wonderful holiday season!

It's nice to see you building again. :) I wonder how a pretzel knot would look? It would certainly flow well with the drop. 



I'm not done building yet.

That looks really nice! I see that you aren't really targeting any other style other than a looper, so this opens a lot of opportunities to be unique! I like the immelmann idea Ghostbuster has, but maybe make it an inclined immelmann. There aren't a lot of those around. Actually, do any exist? I know black mamba at phantasialand kinda has one, but thats more of an upward helix with a twist out at the top.

I like that shaping a lot! Nothing like a good S-bend. I'm not sure if you're going for inversions, but if you do, I'd really enjoy seeing a non-inverting loop. The twist would be tight on top, but it would look cool. Has anyone built one before?

^ Hydra's first element is an inclined dive loop, so sort of...

Hello, all!

Thanks for all the replies!
I didn't realize how fast I was going to be building the next element, so I should have updated this a couple days ago.

I decided with an off-axis vertical loop. I don't really know if I was targeting that at first, but I think I got the look that I wanted pretty well.

Those are all the pictures I can share now :D I am aware of a couple shaping issues; when I went to reinforce the track with connections, some knocked the shaping off. Adding on the outer tubing also made some parts more apparent.

My next element is most likely going to be a dive loop. This is my first time making a looper (and probably my last) so I'm trying to make my elements a little bit different. A dive loop has been challenging so far!

Anyway, cheers!

I was originally going for a very cookie-cutter layout, but I always like trying add in a couple small turns. Definitely makes a ride appear more unique. Thank you!

Nice Job!


Thanks!

My next element is a plain, ol' dive loop. It's not that interesting, but I like the look of the overall flow. Still working out some sharp and straight spots on the pull in, but I do like the shaping from a lot of angles.

I appreciate the comments. I am going on vacation for a few days and this was as far as I have gotten. I will be thinking of my next elements while on break. I hope to fully automate this ride with hopefully 3 running sets of trains. Most of the layout should get done before I leave for college.

Have a Merry Christmas!

That loop is funky in a classic Arrow sort of way. I like it. The dive loop looks great too, and if the train makes it then you're doing really well on speed!

Thank you! I got very, very lucky with shaping it. I got it on my first try! I was very surprised with myself, and a few reference photos helped out.

^Seconded, that dive loop does look perfect. Also, that vertical loop looks so weird - but in a good way. I'd like to ride that in real life.

It happened because when shaping the top part, I realized I wouldn't have enough speed to get the height I wanted, so I curved it a bit early. Funny it came out not looking bad and makes the ride seem unique!

Now that you mention it, it does give off an Arrow feel. The train flies through the loop no problem, but is about 50-50 on the dive loop. I'll have to keep maintaining the train so it consistently makes it when I need it to. However speed does die out from here ;)

___________________________________________

Wow, thanks guys for the comments! Means a lot. I always have a reward for that! More coaster!

I decided on building a zero-g roll. I tried to model it after Hydra's. It is a bit odd because the pull in and pull out are curving away from the roll. Makes some pictures rather ugly.

I didn't get so lucky with the roll as I did the previous elements. Took me multiple attempts at shaping and then the train wasn't even close to making it! I am proud of the result, bht I think the pictures make it look better than it really is :P

My next element will be a raised banked turn into an MCBR. This will have a chain on it so I can cheat a little bit and get a tad bit more height. After this, I hope to get a corkscrew and a helix, with a brake run and into the station.

It might end changing, but we'll see how my speed goes.

Heights of elements where the track is at its highest point:
Lift - 10 granites
Loop - 8 granites
Dive loop - 7 granites
Zero-g - 5 granites

I'm sure you all are itching for a test video, but I will include that following the completion of the next element :)

The shaping on this is fantastic. I think the entry and exit of the zero G roll are a little bit too drawn out but it still looks great. 

I like your plans for the rest of the layout too.

Some more track to support connections might help to keep a little bit more speed, they're a little sparse.

Looks very smooth, although the pullout from the diveloop to 0-G roll seems to have a straight spot. But is is hard to tell from this perspective.

Yes, you're definitely right. The entry and exits are a bit drawn out and I think it is because my first attempt was a bit bigger, but kept the same positions for entrance and exit.
I agree, my TTS isn't all that great. I wasn't really focused as much on that as I should have been. I will fix that when I get the chance. Thank you!

That 0-g roll is downright gorgeous!



Thanks :D

Yes, the straight spot appears because of the rising turn and the combination with that photo angle. Pretty difficult to fix, but I'll continue to take a look when I can. Thanks!

^^, Thank you, I really appreciate it!

__________________________________________

I have a quick, little update for you all today. As I said in the previous update, I was intending to work on the automation while at school. I have been pretty busy, but I have been able to get a good chunk done.

To start out, this isn't my first attempt at software-based automation. For my roller coaster internship project a couple years ago, I was able to create an automation that worked, but was very unreliable. I used photoresistors and room lighting to detect the presence of a train. Like I said... it worked... but not very well. Immediately upon thinking about light sensors is that light isn't always there. The software I had also written wasn't very good at managing signals occuring at the same time. Now I'm here with my solution.

I wrote a simple State Machine program that would listen to each sensor (4) using multiprocessing. I could bring in that data and interpret what data was important or not. I decided upon using magnetic switches that would indicate whether a train was present or not, a much better alternative than arbitrary numbers from a photoresistor.

By now, keeping track of each train object, I can initiate the following state and activate necessary motion of a motor or servo for the block on the coaster. My logic currently works with testing, but on a larger scale, I would need to test on an actual ride to make sure my ideas work. With using a State Machine, I can ensure safety that trains will never collide.

Here you can see my Raspberry Pi. I have 4 wires on the right-side of the pinout that act as switches. I pull them out of ground to indicate a train not there, and put them back to ground to indicate train is there. These 4 wires will get replaced by the magnetic switches in the future, but the wires are used for demonstration.

Here's the magnetic switch. It is indeed very tiny.

Each LED represents a motion of control. On: motor is running. Off: motor stops running. I also have a motor control chip and all I have to do is transfer the electronic input from the LED to the motor controller to turn on the motor and not LED.

I will add a demonstration in a further update if requested, but I hope you all enjoyed this reading and I can't wait to implement my idea! Let me know if you have any questions :)

Loving this coaster soooo much! Reminds me of the B&M looper I built but rather a wacky more spread version very very smooth shaping.
Interested to see the automation in action on this, I done something similar in school a few years ago but only had a brake run, switch track and station but no layout to really test it with. Just wondering what programming language you’re using?

Thanks! I'm just using some python to do what I need it all to do. It's a very dynamic approach to automation.

Hey, all! I'm back with an update that includes the last two elements of the ride. I'll show some pictures and overviews and list the one concern I have.

I decided to go with a corkscrew-ish roll. Not sure how I would classify it because it incorporates a couple different attributes of elements, but I thought it came out looking pretty good.

And just a quick photo of the MCBR. The train obviously doesn't clear the MCBR by itself and needs help from the chain. I have to cheat a little bit to get just a little bit more height.

That's all my photos!

My main concern with this is that the train doesn't completely clear the helix. When I relubed my trains, it did, but not consistently. I also remade the helix multiple times and made adjustments to the vallies of each element to conserve speed. The current state of ride is not what is shown in the pictures, but if anyone has a better idea for an element other than a helix that would fit the ride, please let me know! I haven't been this frustrated in a while with a train not clearing an element and may need suggestions!

I hope you all like what you see, and comment how you would classify the twist element! I am quite curious! Also, since I won't be able to update again until the summer, feel free to ask some questions and I will answer them in the comment section. Hope your semesters are all doing well!
