John, what a delight to see the end result! A very creative scene that goes far beyond the usual static scenery of a model! Bravo, sir! Although I have other areas in which my creativity is focused I can appreciate that you had to plan, design, test, tweak and work a lot to make the finished product. God bless you, John! Well done!!
Andrew, thanks for your kind comments. If you appreciated this video, I'm certain you'll like the next one that is going to be even more unusual and innovative. But it will take me about 4 months to make the new model.
4:55 You don't need the external pull-down resistor. The Arduino's I/O pins already have an internal pull-down resistor that's takes effect when you configure the pin with INPUT_PULLDOWN.
Earlier Atmega CPUs don't have that, just internal pull-ups. Of course he can just wire the reed switches to connect to ground and invert the meaning of the inputs.
Hi folks, I suggest using needle nose pliers or similar to hold the reed switch wires between the bend and the glass to further minimise the risk of damage. This action model looks wonderful does n't it!
Interesting to see this now. A few years ago, we used this system for a professional exhibit. But we used hall sensors and replaced the DC motors with servo stepper motors, so we could get synchronized travel, repeatable speed and just used one hall sensor per track as a reset point. Also used a fast Arduino Due.
For something basic you don’t need a fast microcontroller. The classic arduinos are slow but are definitely fast enough for models like this, people have even made drones with classic arduinos and they require a lot more precise timing and computation than a model. If you find you need a more powerful microcontroller for something basic it generally means you have inefficient or lazy code. You should also use everything available to you. Driving stepper motors directly from microcontrollers is a waste (not saying you did but just pointing it out). Just get a cheap stepper driver and then all you need is a signal to tell it the direction you want and a signal to tell it to step and the stepper driver will handle the actual motor movements and can do things like microstepping to get smaller steps or if using “silent” stepper drivers then the motor itself won’t make any noise.
@@conorstewart2214 For each level of micro stepping for example, you also need to provide double as many pulses to the stepper driver, for the same amount of rotation. So again having a fast micro is advantageous. Actually a lot of examples where the good old 8-bitters CAN perform, but DON'T particularly well. And there is no reason to optimize software to run on an underpowered micro if you're doing a one-off.
Do you know about state machine programming? It's where you have a place in the code for every combination of events. So, the initial state would be "motors off". The next state would be "bicycle running before accident". The next state would be "bicycle stopped, rider thrown". Etc. The transition between the states is driven by the inputs, or a timer. So you would have a timer with a random timeout (so the scenario gets run at random intervals), which gets set when entering State 0 (motors off). When that timer fires, it sets the state to State 1 (bicycle running before accident) and turns on the motor for the bicycle magnorail track. It stays in State 1 until the reed switch fires saying that the bicyclist has reached his doom, then it enters State 2. Etc. It makes it very easy to make a script, because once you have created the engine that drives the state machine, the states themselves are like Lego(tm) bricks. If you want to change the script, just move the states and their actions and their triggers around.
Hi John, I know I'm 3 yrs late in getting to the party, but what you've created is amazing. I'm now looking at doing something similar to my railway. Would there be any chance of a glimpse of your schematics and arduino sketches.?
OMG ! John, thank you SO much for 'introducing' me to this ! - I had absolutely NO knowledge of Magnorail... I did some work for Gerry Anderson on Thunderbirds (a very long time ago!) and know he, as I am now, would have been stunned at how useful this could have been !!! Take care, Mike
I'd never heard of Magnarail before watching this, and I', so fascinated! :O The thumbnail looked particularly wild, like a robotic looking spin fossilised in stone :O Regarding Arduinos, I have a few genuine ones I got from Maplin years back (remember Maplin? :O) and I used those with the ISP program to problam bare chips. I can make incredibly miniaturised circuits that way
I used to run and get the maplins catalog of parts like it was my childhood comic 😊 Helped with tearing down vcr's and things for investigation. Loved brass and steel mechanicals in electronics.
@@luminousfractal420 I took apart an older model VCR a few years back, and the mechanism and arrangement of components compared to more modern VCRs is so much more wildly complex and satisfying :D The VCR really is the perfect marriage of electronics and mechanical engineering
First of all, this is a very good scene and takes Magnorail way further than I have seen before. Here's a suggestion though, something that would add a bit more realism would be to extend this concept to also control the speed of the Magnorail motor slowing it down so it's more realistic when vehicles go round corners.
What an incredibly beautiful diorama with Magnorail. Thank you for your explanations. Best model railway greetings from Germany and thanks for sharing!
Coming from experience, any unsealed wood or cardboard creation will eventually succumb to humidity and will suffer warpage and breakdown, unless you live in a desert or a salt mine of course. You can use paper and cardboard but the trick is to paint it and seal it from the elements with a doping agent like a varnish of some kind.
I'm baffled why anyone would use a computer for this. The whole thing can be done with basic electronics and the most complex component you would use is a timer.
Can I know what is your light setup look like? It look fantastic, almost like natural light on cloudy day. And because some part like the horse look shiny, it almost look like they all wet, and the light make it look like it just stop raining
Would have liked to see more about the assembly, configuration, and operation of the track underneath. I suppose I should see if can look that up. Anyway, very charming scenario for the sequence.
Now Scale it up from a Mini-Miniaturwunderland to a Miniaturwunderland. This little piece really leaves you in awe of what the guys in Hamburg have created.
Magnetic reed switches are most commonly used as part of a stainless steel float, that sits in a gas tank. When the float (which contains a magnet) drops to a certain level, it causes the two parts of the reed switch to stick together, completing the circuit. So it’s a low-fluid level warning device. This guy is using reed switches horizontally! That’s new.
1 Ardunio or 32 Arduinos -- Depends how many triggers and actions you want. 1:1 your good, what if you want one trigger and 5 actions, or 5:15. Easier to use one.
No idea how or why I'm here on this channel, but thanks TH-cam! This is just amazing! Mad skills on so many levels! Looks like fun, but no way I'd have the patience for all this.
Use a pair of fine needle nose pliers (plastic if you can get them) to pinch about 1/2 mm away from glass, and then you can bend beyond the pliers as needed.
I'm currently building a small railway and incorporating magnorail. I thought I would mention how I plan to handle the warping / disintegrating photo card due to moisture issue. I've chosen to snip off the mounting points on the "track" and I'm gluing down strips of 8mm foam around the entire track area. Similar to how the cork is done in the video, but snug against the track. When I'm ready to plaster, I plan to remove the magnorail system, and cover the foam not with the photo card, but with some styrene sheet I have on hand. When plaster and maybe even landscaping is all dry, I should be able to slice out the styrene, fit magnorail and glue down the photo card. Even still I worry about the card. Is yours still holding up OK I wonder? I would love to use an arduino or two for triggering events along the bike path. Really fun idea and execution. I love the accident videos for inspiration. Thanks for sharing it.
Make sure the plaster is completely dry if you are using photo card or it will delaminate with the moisture. I prefer styrene or polycarbonate sheet. Good luck.
@@johnsminiatures8955 Ordered arduino starter kit today. Should arrive tomorrow. My magnorail channel in 8 mm foam is almost all glued down. It's tricky since it's all new construction and it's also my first time working with all of these materials and components. Fun times. Now here I am considering adding more to it.. will plastering ever get done? Is there a place I can check out your code by any chance?
You say you put in extra magnets to trigger the reed switches due to the orientation of the magnet that drives the bike or vehicle. Couldn’t you just put the reed switch under the track and use a single magnet?
Marvellous stuff! Something to delight me as a 50 year old, but the 'magic' of it would have fascinated my (former) 5 year old self even more! Could vehicles designed for the Faller Car System work? Advantage being having working lights (though no doubt functionality would be limited versus a proper Faller road system), but maybe the front steering would function more like a real vehicle. Obviously the vehicle would need the motor to be removed or mechanically isolated. Problem with the Faller system seems to be that the vehicles need to be quite large to accomodate the drive system and battery, meaning that you are restricted mostly to commercial vehicles. With Magnorail, normal cars, as well as bikes and presumably motorbikes, could be used- but not as autonomously, since all vehicles on a chain would start and stop together. But I bet both systems could at least be used side-by-side.
Magnificent work. I've been trying to solve a problem with simulated running water. I've been relying on analog motors to transport a card stock "stream". I wonder if this could be harnessed for same? Cheers!
This is outstanding and very clever. I want to build a variation of this idea and wonder if the script for the Bicycle Accident is available. It would be a good starting place.
I'm starting work on a brand new model in the new year which I think will intrigue people! If you subscribe to my channel you will be notified when the video goes on line. Thanks for your interest.
Polycarbonate is a higher temperature plastic than many that people generally work with. If you’re warping it with lighting then you’re probably going to have plenty of other problems too.
The sequence that I saw was quite funny; the “magnetic” cyclist appears to cycle out of the barn > along the road and between the chevron signs and crashes > the ambulance appears and drives to the crashed cyclist, picks it up and wizzes off and the camera panned to the church yard and “there is the cyclists grave being dug” 😄
I build static models, most of the time, but i wonder if one could use black sandpaper for such a road? It looks like asphalt and can be altered to show wear and tear, the impact of the seasons etc. For static models it is quite nice.
hi just found your channel what a brill idea have you any more details of programing via reed switches i have a faller system and would like to add some effects chers Gary
