Controlling 6 steppers for Orrery

I'm currently designing an orrery planetarium and my current mechanical geared design is rather dense (See attached images) takes up a lot of space, and would involve a lot of gear fabrication. So I'm wondering if I can use 6 stepper motors to run the system and do the ratios in code. If it helps reduce the cost, size, and adds more control options (like inputting a specific date and having the planets move to it) it could be worth consideration.I'm just currently unsure of the best way to control 6 steppers. I'm looking into an Arduino Mega for starters, but I'm not sure how much I/O I can get away with. I plan to just do tests with one motor at a time until I've got six running.The good news is the inner orbits are a smaller diameter involving fewer rotations per orbit and while the outer rings are larger and although they require more rotations per orbit, they move much slower. I can probably find a way to add limit switches if necessary and the I/O allows it, which might be nice for calibration. I don't see this as something I'll be running all the time, since I could see it needing a power supply and long term continuous operation may not be possible with the motors. I'd be open to using servos instead if they could use fewer I/O pins and still rotate continuously, but I'm still doing research. I'm open to any suggestions, ideas, or criticisms for this approach and any assistance is appreciated.For now, I'm still in gear land.

Make Cement From Scratch? Answered

I have spent a great deal of time working on this question yet, I have no solid answer to go on.  I tend to enjoy acquiring a skill set which would be very useful come TEOTWAWKI (the end of the world as we know it).  I am far from a prepper, however I still entertain a slight possibility and see no problem with learning how to do a little more than cope. These skills extend from knowing where to grow, gather, and how to store penicillin to simple things like a yeast starter 100% from scratch.  Brewing and distilling are also handy because it makes a great trade item.  These are all things you never see in the Walking Dead or any other TEOTWAWKI cinema.  One of the more important skills I believe would be conjuring fortress walls from rocks in the form of a little thing we know as concrete which we all take for granted.  Now I could mix portland cement and filler with some water all day long and make a pretty cool fortess, but seriously.  All the home depots in my state wouldn't have enough quick rite for that.  So today I wan't to know what general rocks and minerals (that you can find in nature) can you combine to make cement.  I know there are all kinds of fancy names for these, but what I really need is some good old generalities.  Tell me to go outside grab a handful of clayish dirt, but it in a kiln with some lime and grind it up.  I'm not looking for top of the line stuff here, this just needs to be able to hold a general form for a few years and be a little bullet resistant.  This is for a crude fort, not the tallest building in the world or the hoover dam.  A simple mortar would also be nice, although there really aren't any stones around to put together, bricks aren't super hard to make with as much clay as we have in our soil. So join me and maybe I will put together an instructible on all the skills you actually need but don't have!

3d Printed Concrete Forms for Architectural Post Tensioned Concrete Sculptures

I am looking at the feasibility of 3D printing concrete forms to make a staircase that goes up a 4' retaining wall. The forms would be cylindrical, split in half, and during the pour would be supported using a wood support system. Ideally I would have one main highly curved support "column" (think more of a snake or spaghetti noodle) with then stairs that slide in via a mortise and tenon type connection. The stairs would be poured individually in a separate production process than the main support. I plan on using a combination of a wire mesh, rebar and tension cables for the concrete reinforcement. The tension cables would run the length of the main support beam and would be hydraulically tensioned just before the formwork was removed. I have ample concrete experience as a civil engineer and a construction manager but this idea seems like I need some outside input.Does anyone have any experience 3d printing concrete forms. What is the best material that will hold up to the moisture and high alkalinity of concrete?At this point I have no real conceptual drawings but I'm looking to see if any similar projects have been attempted and hopefully learn and improve on them!

What better ways can i run this generator off of? What motor can i use to take the place of that broken engine? The engine speed is 3600 rpm.

PVC pipes and winding Tesla coils....

There are still people out there playing with high voltage.And one big problem when it comes to Tesla coils is winding the secondary coil.Now, I won't go into the details and options of the actual winding part, instead I would like to share some tricks that might make things easier for your project.Whether you wind fully by hand or make use of some mechanical winder, magnet wire is a very slippery thing on PVC.For that reason and some others we usually wind as tight and close as possible.Any leftover spaces that you find after the winding is finnished will severly compromise the overall tension of the wire in this region if fixed.Next problem is what many call aging.No matter how good you coat your coil with varnish or paint it will start to degrade over time.I found a simple fix for these problems :)Well, not really that simple but I am too lazy today to make a full Instructable for just an addition that everyone can make in a few minutes....Let me start with idea behind it all:I noticed that no matter how thick the pipe or wire is that there is little to no chance at all to get any of the coating material through the wire and all the way down to the PVC.One coil failed after I abused it so I did some cuts and had a close look with a magnifying glass.The coil itself was really good covered but it was like a sleeve that sits on the PVC with nothing on the underside of the wire except for a few single spots.Some people will now say to just a much thinner mix for the coating to allow the stuff to sweep through but that does not always work.One big issue I noticed is that not all paints or varnishes actually stick to PVC.Especially those non smelling eco friendly ones most places now sell.This means when the coil expands due to the vibrations and heat the wire can simply rattle off the varnish or the coating itself can crack under the stress.So I thought there must be a way to fix this right at the winding stage....PVC is a good insulator too!So why not use PVC instead of messing with other things?My first attempt here works quite well with thin wire and goes like this:Go outside with your winding rig and have a bottle of PVC primer and a little brush or sponge ready as well as some gloves.If you have use a friend, if you have none make a small rig to hold the sponge right in front of your winding area.The key is to keep the sponge wet with the primer so it will wet the pipe properly.Best is to have the speed and distance set so the surface just starts to dry off under the wire.The primer will cause the PVC to soften, so the wire slightly sinks into the surface.An automatic winding rig is best here as it allows for consistency.There is no too much or too little here is nothing drips terribly and your wire sticks without fully sinking in.Once done you can cover the winding with your prefered coating.For thicker wire, lets say 0.3mm or thicker, I now use a similar way but with more preperations:Using some very rough sandpaper on a belt or vibrating sander I create a small pile of PVC dust.If you prefer some fancy color you can use ABS plasic here too and it dissolves in a similar way.The resulting mix should be free of lumps and of even color, if in doubt use more primer.Consistency should be a bit thinner than honey, if yours is too thin you can add more ABS/PVC or let the primer evaporate off while stirring it every now and then.To get a good start I do a few turns dry first with quite a big spacing.When approaching the actual start of the winding area I use some stick tape to make the last alignment and start to apply the mix onto the first bit of the winding area.Some lint free cloth with a bit of primer is used to wipe off any excess towards the still uncovered part of the pipe.Every time the mix on the pipe dries out too fast a brush with some primer is use to wet it.Every time the excess runs out a bit more mix is applied onto the wound area.The key is to only have a small area in front of the winding covered with mix with the most is on the winding and "cleaned" off towards the empty area.This way the entire wire is covered by PVC all around.To finnish off you simply use a brush and paint the mix onto the rotating coil until you have an even finnish.What are the downsides?The primer stinks and is certainly not healthy to breathe in. So good ventilation is a must have and it works better in colder temeratures as it gives you more time.It might require some test runs with braided fishing line or similar to get a feeling for how much mix or primer you need to apply and how much max tesion you can use to preven the wire from sinking in.Any benefits?IMHO using this method makes it possible to get a proper bond between the PVC pipe and the wire.And by using PVC or ABS as the coating there is little to no change material properties.This in return gives far less chances for vibrations or wire expansions that result in failing insulations.The whole thing just is one piece of PVC with the wire embedded in it instead of having a wire on top of the PVC with some coating above. ;)Are there alternatives to the PVC primer?If Acetone is much cheaper than you can use it but the same safety measures apply and the mix might dry a bit quicker.What if I need a break or stop the winding for one reason or another?Simply wipe off all access and stop with just enough tension on the wire so you can star again with no problems.Then start by wetting and applying the mix and continue winding as before.

Torque to linear thrust through lead screw

Hi,I am trying to figure out maximum linear force I can produce with an electric motor through use of lead screw and nut. I have come up with an equation which seems correct but resulting forces are way higher than my intuition believes is correct.I tackled the problem from the perspective of energies:F' * p = M/r * 2*π*rlinear force * thread pitch = torque / radius [M/r = force at radius] * circumference of lead screwF = 2*π*M/p * (1-k) //k stands for coefficient of friction between lead screw and nut)Radius falls out of equation, which seems fine as force is provided by torque, which is radius agnostic. I used a 7€ stepper for source of torque which can provide 0.42 Nm of torque and a lead screw with 8 mm pitch and 4 mm radius, I assumed 15% losses. My equation tells me that such system can provide 280 N of force, which seems wayyy too much for a cheap motor.I have attached a python code that calculates linear force in case it helpsCan someone tell me if my equation is either correct or flawed?

I am looking for a 220v/50Hz to 110v/60hz step down transformer - any help please? Answered

I want to purchase a computerized sewing machine for my wife from the US, however this machine is VERY sensitive, and manufacturer does not recommend running it on different voltage than 110v. I have checked with them, and the required input for it is:2.4  wattage. The amp is .02 and the voltage 120. I have not managed to find a reasonably priced step down transformer which can also transform the frequency - only one, but it costs a few thousands of dollars :)Please, help! This machine is not sold here, not in Europe, not even similar model. One answer I've got from a company specializing in such reliable converters: Since your sewing machine is computerized and very sensitive we do not feel confident that it will work properly with a voltage converter because of the cycle or hertz difference.  Here it is 60 hz and Israel it is 50hz and converters do not change the cycles. your sewing machine may be adversely effected.

Identifying plastic so I can weld a repair

I am repairing a broken wheel on a old lawnmower for which spares are not available. The hub (holding the roller bearing) has broken away from the rim and tyre. I've managed to weld the two parts back together using the hot air gun on my rework station but some small pieces are missing and I'd like to replace these and reinforce the welds by adding material.It is possible to buy rods of different plastics to carry out these repairs but I need a better understanding of the material I'm working with. It is an opaque white plastic with a greasy or soapy feel. It melts relatively easily (I used the heat gun at 180 degrees C) and bonds back to itself well. I suspect it is a polypropylene of some flavour - straight Polyprop, HDPE or LDPE.I don't have scrap material to test without removing some from the wheel. Any thoughts on what it is likely to be and do I have to know exactly which it is or will the different materials bond with each other?
