Bottle roller help

So i have bottles ranging from 60ml to 500ml that i'd like to make a roller for mixing. The issue is that the only mixers like this are in the $1,000 and up range, it's honestly criminal. see here http://amzn.to/2h6gHYG Anyone have ideas for parts to make a super cheap version of one of these?

Chain Keeper/Roller

New to instructables forum but have been enjoying all the wonderful inventions.  I am trying to make/build me a chain keeper that "looks" like the following: 1. Pedros Chain Keeper (http://www.amazon.com/Pedros-Chain-Keeper-Bicycle-Tool/dp/B000IZEH1K) 2. Butter b1 Chain Keeper (http://www.bicycling.com/gearfinderproductdetail?gfid=66448) These chain keepers are quite expensive: about $10.00 for Pedros and $35.00 for Butter. Also, I'd like the chain keeper to be used for transporting my bike - see a comment on a DIY version at http://www.bikehacks.com/bikehacks/2012/06/diy-bike-chain-keeper.html Appreciate any input/ideas. Cheers.

Roller machine to create pressure on and pull through ribbons of bark/fiber, similar to a pasta maker--ideas NEEDED.

I'm working on a project in Nepal to remove the bark from the fiber growing in the stalk of a wild plant (bast fiber). The "bark ribbons" are stripped off the plant, with the fiber adhering to the inner side of the bark. The plant grows back so it's all very environmentally sustainable. We soak the long (1-2meters) bark ribbons for 24-48 hours and then, if beaten, can break the "glue" (pectin) that's holding the bark and fiber together. We've run them through an industrial  roller system and it worked very well, without damaging the fiber the way beating does. A local machine shop wants to build an expensive, heavy duty, roller system and we'll go for this eventually. However, in the meantime, we'd like to build a smaller, simpler machine, maybe a table top one rather than free-standing. We can hand crank it, or use a bicycle mechanism. We need to be able to adjust the pressure--the distance between the two rollers--to make sure we are breaking the pectin bond between the two materials, fiber and bark. We have access to steel pipe, PVC, cast iron makers, gears, etc. If anyone can help me with plans I'd really appreciate it, as would many impoverished Nepalis. I've included photos of the industrial machine (the first 6) we tried and will eventually make, as well as a pasta maker and one other machine. The industrial machine had three rollers but they removed the outlying one, not above/below another, as it didn't work as intended. Thanks so much in advance to all you wonderfully creative Instructable-ers. Shanti Mama

computer controlled rc car roller coaster

A new idea i recently came up with was to use the ir feature in the wiimote as a gps tracker for line of sight communication... basically, the idea is to build a framework (knex pieces maybe) and then make a track out of something else with lots of turns, ups/downs, a jump or 2, and a stunt track (kind of like a skiing terrain park) on the roof... also an elevator in a corner to take the car up, and finally 2 spiral tracks to also help the car get up easier. i will eventually make a sketchup version of this track and post it, right now its just on paper but still, the layout idea is almost done.the idea is to mount an led throwie thingy using an ir led an a locking push switch (push on, push off to conserve battery life) on the top of an rc car such as a mini cooper (pic 1). i will mount the wiimote at an angle on the top in a way so that the whole track is visible (or as much as possible).heres the idea: the car remote should be hooked up to the computer, and there is a way to do that if u google it an/or look at thisthe wiimote will track the car using the ir, and the computer will then steer the car accordingly. Advantages to that are : 1. the car can start anywhere on the track; 2. there is no need for borders like those "ai" cars which use ir sensors to drive their way around, which i happened to mention in another forum of mine so refer there for pics + description; and 3. it actually tracks the car's location, instead of just avoiding obstacles like those ai cars. this would allow realtime tracking, so it knows to stop the car when it eg. gets to the elevator, ect... now - naturally, this design will have some "blind spots", so there will be laser "tripwires" in those more major areas and have those signals routed through a microcontroller, which will then send out a # respective to the tripped area then routed to the computer, just like an advanced alarm system. for the controller (hooked up to computer), it would be nice to have the whole thing routed through and powered by a single usb port, so instead of integrating a hub, is there a microcontroller that is designed to directly interface with a computer, not just for programming, but for actual realtime commands and stuff like that..?as far as the forum goes, this is just a huge idea now and we each have our areas of expertise... so m asking for ideas about harware, materials, coding, and especially how to directly interface the program to the wiimote...also, comments, questions, and anything else u got is welcome and greatly appreciated.Thanks to all, rak

Small model roller coaster - how to build the lift?

Hello, I've accepted the challenge of building a small-scale (no riders) roller coaster model for use as a prop in my church's vacation bible school next summer.  The vehicles are based on skateboard trucks, and the track is made from 1.5" PVC cut in half lengthwise, secured to a wood frame.  Motion is all gravity-based except of course for the lift hill, and that's where I'm stuck looking for a good design.  The vehicle is expected to remain in motion without intervention for a few hours a day, so the lift needs to engage the vehicle at the bottom, lift it to the top, and release it reliably.  The frame is still a work-in-progress and is easily modified, but for reference it's about 30' wide by 8' deep.  The height of the hill top is also still undefined but I'd expect about 6 feet or so, with any reasonable slope.  Any suggestions?  Thanks for any ideas.

Safety of your garage door or car remote...

No time and no pics for a proper Instructable, so I just put out some word of warning ;) Around here bad people take advantage of the fact that a lot of new houses have the garage right next to the house. With these you usually also get a door so when you park your car you don't have to get out of the garage again. All controlled by the press of a button on the remote... Some fancy guys got a device working similar to the IM-ME Open Sesame hack a few years back. But unlike the original author the new guys found ways to make money by providing working "universal garage door openers" on dubious websites. Problem with the new model is that it not only fakes a remote with dip switches but also the newer models with so called "rolling code", "intellicode", "changing code" and so on. The old remotes with dip switches should actually by phased out years ago by any owner who values his stuff... But the new models are still deemed secure and next to impossible to hack - well if you trust the advertisement... How does the code hacking work? The old dip switch models allow for a maximum of just over 4000 different codes and come in just 3 or 4 frequency bands. No real problem for anyone with basic electronic and coding skills to hack these - as shown with Open Sesame. The new models all use a so called rolling code, here the remote and opener are paired through 32 bit of ID code and an encrypted part that changes every time. Both remote and opener calculate the next code once a button was pressed or a code received. To overcome reception problems the base usually calculates the next 256 codes in advance - and that is the entry point for bad boys. The illegal device scrambles the frequency detected while storing the code received by the orignal remote. As the door did not open the owner will try to press the button again. Still scrambled to opener does nothing - until the device sends out the first recorded code! Now the owner can drive in and is happy. Of course he still needs to close the garage - again all is scrambled and the code stored as before. You see where this is going.... It is even possible to set the amount of required tries to capture, so in theory a bad guy could get the next 10 or codes in advance for use once the owner is gone out... Worst thing however is that these illegal devices not only open garage doors but also cars as a lot of them use similar systems for their remotes - up to the point of starting the car with it. Took me only 2 hours with Google translate to find a website outside the usual search results that offers these "gadgets", along with WiFi and cell phone jammers, credit card copy devices and more things I don't want know about... What can you do to protect yourself? First check what type of remote your system uses - if there are DIP Switches than replace the remote system or the entire device in favour for something more secure. If you already have a rolling code model that you are far better off but sadly no longer totally safe here. A lost remote should not only be replaced but the old one removed from the system as well - you never know if you just lost it or someone took your remote ;) Alternatives exist, especially if you are not afraid of doing some open heart surgery on the electronics of a garage door opener. You can add a WiFi module and use your mobile phone to open the garage - search Google if you like the idea ;) Another very neat way is using a second transmitter that keeps the relay for activating the opener from working. This can be anything from a BT module paired with your phone or cars BT system over a keycard to numberplate recognition cams. A good system also allows for a "holiday mode" or similar. Here you can set this mode with one remote until you deactivate it with the same remote the system will not react to anything. Great if you leave the house for more than a day or two... As a last resort you can always get a big and angry dog to sleep in your garage.... What if you are renting or a bit limited with the electronics and soldering skills? Not all is lost if you can accept a second remote for added safety. These days you can get plug in converters for your mains voltage outlets that work with a remote control. Unless they use Infra Red for this they are great to disable your opener. Simply plug it in where the power cord for the opener is and then plug the cord into it as well ;) Now you can fully shut off the opener with the press of a button and only if the power outlet is switched on the opener will work. If in doubt you can use a double outlet adapter an extension cord and a night light to indicate wether or not the opener has power. Ok, and what about the door lading from the garage into the house? Well, of course keep it locked and if you are home also keep it locked. At least this way you have some extra time in case someone tries to enter through your garage while you are sleeping ;)

Rebuilding NordicTrack ski machine drive rollers

Many people still buy and use a NordicTrack Ski Machine, although these machines are not as popular as they once were. I have talked to people who say they just plain wore out a ski machine. The part that wears is the one-way clutch inside the drive rollers. NordicTrack makes the one-way clutch sound very mysterious. In reality it is a one-way needle bearing and is available from Amazon or locally from a good bearing shop. The internal diameter of the one-way needle bearing used in my machine (Challenger, similar to a 303) is 5/8 inch. The outer diameter is 7/8 inch. The width of the one-way needle bearing from end to end is 5/8 inch. I originally had hopes of being able to install new one-way needle bearings, myself; but, they together with the bronze sleeve bearings on either side of the one-way needle bearing inside each drive roller are pressed into place. Pressing bearings is not a job for the average home tinkerer but requires a bearing press capable of exerting tons of pressure in a very precise manner. You can often have a local machine shop press the bearings in your machine's drive rollers. Or, you can send them away to Nordic Track Guy and have them rebuilt for about $33 with a one week turnaround. The core of the rollers really does not wear out, but new rollers are available on the Internet from $65 to $95, depending on the vendor. From what I can find, some models used an alternate size. Check to be certain you order the correct rollers, if you choose to replace. One of my drive rollers suddenly began to hiccup. It seemed that the clutch did not always release immediately when I pulled my foot forward. Then I noticed a little mush in the response when I began to bring my foot back on the push stroke. Before you rebuild or replace your rollers, try this: Remove one side of your Ski Machine. See the second photo and check the exploded diagram in your manual. Four nuts and two screws, all plainly visible, need to be removed. Slide the washers and the roller off of the top side. The shaft and flywheel can be wiggled out of the other side without removing anything from that side. Remove the washers and the roller from that side, too. Flush the one-way needle bearing by squirting some penetrating oil, like Liquid Wrench, into the bearing. Work it both ways with your smallest finger. Push a facial tissue into the shaft hole in the roller and sop away the penetrating oil and any metallic dust it lifts. Do this several times. Let the rollers air dry. A little lubrication is good. People who comment on lubrication for one-way needle bearings use Tri-Flo (I am not familiar with it.) or they use a little ATF transmission fluid. You want enough to lubricate, but not so much that the bearings slip. (But, see the comments below where the oil impregnated bronze sleeve bearings are supposed to supply enough lubrication for the needle bearings.) Put the rollers back in place on the shaft. Check to be certain they grab on the rearward stroke and release on the forward stroke. Reassemble the machine. Do not forget the washers between the roller and the side board. My machine works again as it should. The day will likely come when this simple fix does not help, and I will need to rebuild or replace the rollers then. But, for now, my rollers have a new lease on life. What follows is for your information. The first photo is of a portion of the back cover of the manual that came with my machine. It shows a cutaway image of the drive roller. The black printing is mine. Notice the three cylinders inside the drive roller. The outer two are bronze sleeve bearings. The center one looks like a roller bearing, but is a one-way needle bearing. A one-way needle bearing is essentially a roller bearing, but the rollers are able to move forward and backward a little in their cage. There is a wedge shape for the axle of each roller that causes the rollers to bind between the bearing cage and the shaft when the rotation is in one direction, but they are free in the other direction. Here is a description of how they work with graphics. This link is for an Instructable about a number of modifications I made to our NordicTrack ski machine, including how it can be stored vertically in a closet. If you do not have a digital monitor for your skier, or need to replace one, here is an Instructable on how to make your own from a digital bicycle speedometer.  Check NordicParts for any parts you need, also Nordic Fitness Ski Machines. Danny at Nordic Fitness Ski Machines has some very nice new rollers for sale.
