Making a chain clock...?

I asked recently about making one of these here Re-design gave me some useful advice as to what to use, sadly though, I have no idea where to begin. I know what a stepper motor does, but as far as to what stepper motor to use, where to get one, how to use/program a controller, how to power the motor, etc I have no idea. If somebody could give me some clues, or just point me towards another instructable that explains any of this I would be most grateful. Thanks for the help, Cook$

Mini Bike Chain Adjustment Trouble? Answered

I recently bought a bunch of pocket bikes all in good shape but all had some sort of problem.  I took the best parts off of them and made one extremely nice bike.  The one problem I am having with it is that the chain likes to come off.  There is a bolt connected to the back axle that tights and loosens and slcks or tensions the chain.  How do I find the "butter zone" where it isn't too loose to come off, and it is too tight to come off?  The two sprockets are lined up really well, but they are a little off.  Would it be possible that that was the problem?  When I say a little I mean like so small its less then 2-3 mm from drive sprocket to driven sprocket.

Help with powering chained LED strips?

It's been about 30 years since I had any formal training in wiring circuits, so excuse my ignorance.   I am trying to chain a couple of addressable LED strips.   The strips have the following requirements: Power consumption: 10W/M Length: 5m Voltage: DC5V So it's 50W for the length of one 5m strip.    I'm considering chaining two or more strips together.   The data chain can be as long as it needs to be, but the the manufacturer recommends powering strips every 5m.     Let's say I have a 5v 60A (300W) DC power supply.   Can I run multiple strips (I guess up to six 5m strips) with this wired in parallel, or do I need to worry about putting resistors in to keep it from overloading the strips?    Here's a quick sketch diagram

Soldering/brazing/welding steel, bicycle chains?

Hi, i am working on a project (in Vienna, Austria), and a part of that process will be that i would have to clean a bunch of used bicycle chains and create other, rather smaller objects out of them. they dont have to hold a lot of weight, they vary from 4 to 6 chainlinks or so. At the end I think I will have between 50 and 100 maybe 200 pieces, so it's not an industrial amount but not a single few pieces either. FYI: bicycle chains are made from steel, they are not stainless steel, usually its chromed, there is nickel in it, so when its used they surfaces are often damaged, so it has rust on the surface as well. it has really small hidden parts where grease, dirt and rust stays hidden and stuck too. For the cleaning: I have been cleaning chains to create prototypes and individualised pieces so far with Terpentine and experimented with other types of Degreasers, Soaps, with toothbrush method:) and rags, also other kinds of paint thinners (terpentine doesnt smell so bad, but still removed a fair amount of grease dirt and rust) Degreasers are not very effective, soap and toothbrush and rags take a lot of time. Soaking in terpentine helps but its still time consuming. I havent tried aceton yet. Vinegar and stuff like this dont seem to be so effective either... For assembling/connecting: I have used for individual pieces chain tools (putting a small pressure on the chain link pins, so they are not flexible anymore (as chains supposed to be normally) and then forced bending them in the position they should be in. This is stable enough for the stuff I want to do (they are only decorational) but it's a lot of work, takes a really long time. I did welding too (MIG), but the plates are individual pieces, it doesnt weld so nicely, or its not so easy, and I dont have my own welding machine in my workshop space, I have one in a different place i can use, but i dont want to invest and buy one just for this, and it would be nice if I could do the whole project in my own space, and i wouldnt have to transport so much stuff all the time back and forth... and it's not necessary to have it that strong as i can actually get it with welding, because it doesnt have to be that resistant, doesnt have to hold so much weight, as they are going to be only smaller decorational objects anyway. Ideas and tips that came up, havent been tried yet though, or didnt really work yet: - soldering: with gas flame (torch) and simple solder. i tried shortly, didnt really work though, didnt connect, maybe i give it a try again, not sure what i did wrong though, maybe its just not the right method? - using screw glue (not sure if thats the right name in english:) rather smaller amounts or transparent ones, applying it at the inside points, so it still looks nice. - i havent tried epoxy and i am not a huge fan of the idea, but i dont know enough about the costs, process and the environmental effects of it... - it is an option also to use some temporarily working, not very great but cheap and fast method for assembly as preparation and then just quickly fill holes by welding, i thought about trying soldering or screw glue before welding and just zack, zack zack weld them one bye one, it would be easier if they are somehow already fixed in the position they should be in (as they are small and very flexible pieces of metal otherwise), problem is though that whatever i use as preparation, will be quickly burned by welding, which is in terms of environmental effects not so great, but also has aestetical consequences i guess. - i just read about brazing, i am not sure yet what i would need for it, for smaller stuff, what is the difference between brazing and soldering exactly and how well it would work, what are the costs of investment etc. - for cleaning: one idea i havent tried, just read about it is sandblasting. I would probably have to ask some company to do that, as i really cant afford to invest much more money in equipment right now, not sure if i even have the right space for that, and it seems anyway for 50 or 100 pieces disproportionate somehow. I would like to use a method that is not too bad in terms on enviromental-friendlyness or how to say, not very damaging or too bad chemically etc. it would be important that whatever i do, the endresult: - holds more or less - looks nice, either invisible the parts or things, materials i add so it holds, or it has the same colour/material like some kind of metal. it can be that i will paint it over with some metal silver colour at the end if necessary, for having a consistent colour surface, or to prevent from rusting afterwards. - should be cheap during the process, so low running costs and more or less environmental friendly, and preferably some method to use tools that are cheap or i have access to, not very expensive to invest. - i prefer to do things by myself and not outsource the process to companies unless it has big advantages (like for example if it turns out sandblasting is cheap and really environmental friendly i would consider it actually:))) i am really happy for any tips on these things, before i spend more money on stuff just to try it out and find out it's stupid, or not what i need, not what i am looking for:)

How can I color aluminum wire without annodizing?

I bought a spool of 14 gauge aluminum wire for chain maille. My goal is to have alternating black and natural colored rings used for the maille. In a household metal working book I found from the 80's, they said to,"Mix 2 tablespoons lye into 1 quart cold water. Add aluminum part for 1-2 minutes. Submerse part into household dye mixed according to manufacturers directions until desired depth of color is achieved. Rinse in cold water".I tried this method using RIT black household dye; however, it was not successful. I am trying to dye the wire both RED and BLACK. If no method for the red is found, I can purchase a short length of anodized red wire; however, If there are any chemical reactions for turning the wire black, that would be great. Thanks!!

How can I modify this circuit to sequentially turn on LEDs in parallel, while avoiding voltage drops? Answered

I have a single pole, 12 throw rotary switch which I want to solder to a set of LEDs so that rotating the switch clockwise lights more LEDs as follows: 1 = 1 Red LED 2 = 2 Red LEDs 3 = 3 Red LEDs 4 = 4 Red LEDs 5 = 5 Yellow LEDs 6 = 6 Yellow LEDs 7 = 7 Yellow LEDs 8 = 8 Yellow LEDs 9 = 9 Blue LEDs 10 = 10 Blue LEDs 11 = 11 Blue LEDs 12 = 12 Blue LEDs Since there will be a voltage drop across the diodes, the LEDs at the start of the chain will get progressively dimmer, and increasing the voltage would blow the LEDs in shorter chains. One modification I know I could already make would be to not use the first 4 diodes on the yellow LEDs, and the first 8 diodes on the red LEDs, as a minimum of 5 yellows and 9 blue will be active for each position. This still leaves a maximum of 3 diodes in each chain, which I still think would cause the lights to be much dimmer. Another solution I can think of is to have multiple wires coming from each terminal of the switch, each with their own diode, which would ensure all active LEDs had the same brightness (I'm not sure if this would cause the whole chain to be dimmer than shorter chains or not). The downside is this would need  31 wires rather than 13, and that's only if I bridged together all the shortest LED chains of each sequence: individual wires for absolutely every position would mean 79 wires+diodes). To put this in context, I want to create the health bar from Dead Space 3: If you can suggest a way of improving the circuit, or totally re-designing it, it'd help me loads! Thanks!

How do I make a chain rotating around 2 gears complete a single rotation in exactly 60 seconds?

Hello everyone, I'd like to start off by declaring I am new to this website and have little understanding of technology as of yet. If my question has been answered before I apologize, but I haven't been able to find it in the forum. I've recently started tinkering with 3D printing as a bit of a hobby and am trying to make items that are more than just odd looking. One of the things I'd like to create is the following clock found on youtube: Now this clock is made with Lego and its creator has labeled it as a 'proof of concept' as the 'lift' that delivers the ball, which should represent a minute, actually only counts ~55 seconds. For an actual clock I'd like it to have 60 seconds per minute and I am wondering if I can calulate the specs before I spend money on printed prototypes that dissapoint.. So using 2 Cogwheels/gears with a Chain that picks up a ball every 60 seconds (so a full chain rotation) based on an electric motor. I've found several 3-9v electric motors, but all seem to have rotations in the thousands whereas I'd expect to need like a few dozen rotations per minute(?). The clock I am trying to make is smaller than 20cm and I'd like for the chain to span a max 16cm in the final clock. Summed up: 1) How do I decide the right Gear? size/teeth? 2) What Electric motor/power source would suit a very low amount of rotations? 3) How can I time the motor/gears to complete a cycle in exactly 1 minute? Thanks in advance for taking a look ;)

LED Circuit Design?

I'm a Mechanical working in the LED field. I'm trying to design a LED circuit with the little knowledge I have. Here is my circuit in a nutshell: 3.2 Vf typ - 3.6 Vf MAX -.150 mA 24 volt CV PS supplying 3.3 A 7 series in parallel with 22 chains I calculated using typical Vf as the following: 24/3.2 = 7.5 devices so I rounded down to 7 devices in a series chain. 7*3.2 = 22.4 volts required 24 supplied - 22.4 volts = 1.6 volts to dissipate. Resistance = 1.6/.150A = 10.67 ohms Wattage across resistor = 1.6*.150 = .24 W So I found a SM resitor 10.7 Ohms at .25 W. I have a concern with Vf variance. Would this circuit not work if I get Vf's higher than 3.2 Vf? So if I change my circuit to 6 devices per series chain I need 19.2 volts and need to dissipate 4.8 volts. This just seems like a waste.I still do not understand Vf variance. If I design for 6 and dissipate 4.8 volts with a resistor - won't the series chain be starved if Vf goes higher? So how do you accommodate this variance? I just have worries about this design - regardless if I design for 6 or 7. I know some about LEDs but I do not know what happens when I get Vf variance. Does the resistor go at the end of the series circuit? If this is the case then I understand how variance in the circuit would be able to use available voltage - and then the resistor is at the end to disipate what is left over. I've heard concerns that I'm not allowing for more head room #i.e. doubling the resistor value and wattage requirements). If I double the voltage dropped don't I take this away from the LED circuit possibly starving it? I have always assumed the resistor goes at the beginning of the circuit - regulating the current/voltage prior to it entering the LED series circuit.?

I think I have a cool idea, will it work?

I would like to see a scientific 'domino's' event. My idea is that you have a series of containers with different chemical combinations, and they all have entry and exit areas. The containers would have a starting spot, whereby a chemical would be added to the current combination, to cause a spurt to leave the exit point, and enter the next container by the entry point, this would cause another reaction, and the chain would continue to the next container. I'm wondering if the reaction could be continued for 20 containers or more. Obviously an explosion in the chain would break the next container, so each reaction would need to be thought out to produce a spurt. What's more the positioning of each container would need to be perfectly planned according to the power of the reaction. For the container's I'm thinking something like a glass watering can, with chambers inside if needed to produce the right reaction or effect. The entry point would be the filling rea, and the spout would be the exit point. I think it's a cool idea, and I would love to know if it could work.
