requests to publish instructable for someone else

Having had some recent successful instructables i have been approached by some asking me to publish their instructable, naturally i have no intention of doing so, however i wonder why someone would do this instead of publishing it themselves? i also wonder what the rules are with regard to external links in instructables and if the external links in this instructable are the motivation for this person wanting his instructable on the site. the instructable he has created does not look innocuous as far as i can tell but it is not feature worthy as it has no images at all and that then begs the question whats the point?

Mini Size of "No Coriander" Stamp Magnet Keychain (Picture just added)

I found this D.I.Y mini stamp of "No Coriander" on web search in Chinese and it immediately caught my eye and I really want to make one for myself. This is a REAL useful small craft, but sadly, the maker didn't shows how to make it. Fellow friends, I know this is just a small easy craft for the experts, but I have no experience on this kind of D.I.Y. I'm here to ask for help on this D.I.Y. I would appreciate it if anyone could teach me on the steps and what materials to be prepared. Thanks in advance.

Wiring a 3 bulb lamp

I know this is basic, but I'm not familiar with wiring anything that could potentially burn the house down so I feel its better to ask. I'm wanting to wire up three lights to go over my basement workbench to all work on the same switch. The image shows what I planned to do, was just wondering if there an expert out there who could tell me if this is going to be safe? Would 60 watt bulbs ok?

A question about an instructable to do with clocks I saw a while back.

So if you go up to the search bar and type in the word 'clock', you get all sorts of results. Small clocks, big clocks, plastic clocks, metal clocks, Batman clocks, Skyrim clocks, everything under the sun. Bar one. The thing is, all these clocks are generic. They all are mostly the same. A standard circle with hands and the hands marching round the clock in circles. I'm not saying that this is bad, I'm just saying that seeing the same thing over and over and over gets very boring for me. So when I saw a clock that was unique and different, it was like a dream come true. However, if I try to look for that particular clock again, I can't seem to find it. The clock in question acts similar to the linear clock, but is still circular (hypocrite). Looks sort of like this:                  | ________\|/________ |________________|      |___________|         |________| The top row shows the seconds, the second row the minutes and the last the hours. Essentially, the hours and minutes and seconds all turn while the actual base stays still. The numbers are along the rows and as they turn, the arrow points to what the time is. If anyone can find this instructable, I will be grateful. Otherwise, I will be forced to do this project without the help of any sort of instruction.

Timed control board for a reversible motor

Hello, In need to connect a control board to a reversible motor so that the motor would rotate in one direction for "x" seconds and then automatically switch and rotate for "y" seconds in a reverse direction. I got the following parts in hand: - reversible motor - https://www.amazon.com/gp/product/B01N687NGU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc;=1 - control board - https://www.amazon.com/gp/product/B01HB1X75U/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 - DC adapter - https://www.amazon.com/gp/product/B00S1GRFYY/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc;=1 Control board works and is going through the proper cycle as indicated in description however the motor only rotates in one direction and never switches. Realizing this this something that I am doing wrong with wiring, so hoping for an advice from someone who knows better in terms of how to set it up correctly and which jumpers or anything need to present so that it works and where things should be wired into. I am also attaching an image with descriptions for connectors that I received from the company. Thank you in advance for your advice.

Medium weight quilting Fabric

Hello Everyone, I'm new to this type of project but I was looking to make a knife roll for a friend who will be starting culinary school soon. The one she bought for school is kind of dumpy and while it does the job we had found some great looking roll up ones online they were just kind of expensive. So i figured I could make her one for half the cost. It all seems doable. The wall I'm running into is the majority of my sewing experience has been stitching hems for Halloween costumes so my familiarity with fabric types is minimal at best. I wanted to make her a roll out of a fabric with a print on it and and finally finding the right one, at a good price point, I find myself worried the quality of the fabric may not be what I'm looking for. Basically what I found was described as "medium-weight quilting fabric 100% cotton" another one was called "broadcloth." I, however, have no idea what they are. The majority of no leather knife rolls we did find were made of canvas so I was hoping to make one of similar durability. To sum it all up I'm just wondering if this "medium-weight quilting fabric" is anything like twill, canvas, linen or musslin. I feel like those fabrics, especially the first two, would be quite durable for some like a chefs knife problem is the pattern I'm looking for isn't on those types of fabrics. Any and all help is greatly appreciated. Thank you in advance!

3V Hobby Motor in a 6V Circuit.

Hi. Hope I'm posting appropriately. If not, please forgive an older guy! I'm working on a Useless Box project that I power from a 6V wall wart. I've already completed one and it works great. I use two standard servos with an Uno. But now, rather than being satisfied, I'd like to add a 3V hobby motor, which naturally would only run randomly for short periods of time. I have purchased an AMS1117 step down module which is rated at 800mA from Amazon to get the correct voltage for my little motor. My question is, do I need to add a capacitor across the leads or to the casing. If so, how do I determine what size? And while I'm asking, is there anything else I need to think about? I appreciate any help as this is a new hobby for me.

have i got 1 good driver or 3 bad ones

Hi all, nice to be here I have just finished building my first cnc router and about to start actually doing something with it, during my build I somehow managed to blow up 2 grbl boards and 6 drivers, hey note to myself, don't connect voltages when tired late at night also I have a problem, I think, thanks to YouTube I found how to set the voltage using the trimmer pots on the driver boards, I set all 4 drivers initially to 0.75 volt and it all works and tests fine, apart from having to buy 2 more driver boards when the trim pots fell off that is apart from one of the stepper drivers powers one motor (Y axis) and when it finishes working it goes absolutely solid locked up and sounds like it is groaning, the other 3 are firm but not locked up I tried increasing the voltage on the 3 looser stepper motors to 1.0 volt and it didn't seem to make a lot of difference, but to get the solid stepper driver down to the same stiffness I have had to drop the voltage down to 0.4 volt and it did stop groaning and loosened a bit I swapped over the motors, same result, moved the driver to another spot on the grbl board exactly the same effect on a different motor, so it looks to me like it is the DRV8825 driver board is this a case of I have 1 bad board and 3 good boards? or 1 good board and 3 bad boards ? any help would be more than welcome info on my cnc build and components below basically the cnc has a bed of 900mm x 900mm and is pure self build made up of parts found laying around my workshop, rails bearings lead screws etc, and I added in a new Arduino uno (of which I am novice) and a new GRBL board and ended up using DRV8825 drivers, stepper motors are used (eBay) 4 x identical minebea 23LM-C343-14V wired from 6 wire down to 4 wire with pairs being red & yellow and pair 2 being blue & orange, which I believe is correct LINK TO STEPPER MOTOR SPEC SHEET please correct me if I have made a mistake I have used links to set all drivers to 1/32 micro stepping, also set the mm rate so it is exact at 500mm travel, and set max speed at a sensible 400mm per minute as I am not really expecting supersonic speed and all is nice and quiet, nothing straining I have paired 2 of the stepper motors via the grbl to drive the X axis and used the clone spare on the GRBL to make that work, which it does marvellous The CNC structure does need strengthening up as mostly built on ply at the moment, but everything works as expected, the spindle is a nice almost new RotaZip high speed tool that I bought new about 4 years ago and only used it on one job so keeping stuff does come in handy even if wifey says it doesn't Look forward to sharing info on here as I learn more

Arduino/ESP8266/servo noise when idle

Hello everyone My project involves a robot with LEDs, servos and an Arduino with a Sparkfun ESP8266 shield on top. Everything else works fine, I send web requests to the robot and LEDs are blinking or the servos are moving. The problem is that when idle I have noise on the servo. I have tried  1. Pull-up and pull-down resistors 2. Providing external power to the servos 3. Putting an aluminium foil between Arduino and the shield and the problem persists Commenting out parts of my code I isolated that the noise appeared upon uncommenting this part of my code void serverDemo(){ ESP8266Client client = server.available(500); } but I cannot understand why.  Could you please propose me any idea?

Can an Instructables Member Make Classes?

Hello, I'm part of a company that does a lot of stuff that customers would ask questions about, and I was wondering if it is an option to make classes on Instructables or if that was a potential consideration from your end. I would find it useful, even if it was limited to a Pro membership. It's something that I think personally my company would consider paying for. I would even consider it individually. The ability to make classes that people would want to learn would be invaluable. Of course the only question would be is if others feel the same way I do. If this is already a feature that I can take part in, let me know, as I'm not currently aware of any way to access it, and I don't want to pay for a Pro membership unless I know for certain that that's a feature that would come with it. I would appreciate any answers you can give on this topic. Thank you, and hope you're all having a pleasant day. -DJBarnett

product advertisements disguised as instructables

Fair game, if they try to help to do something, but instead they preface their "problem solution" with the need to buy such and such piece of equipment. I have no problem with this approach, but sure wish such instructables  would be identified as "promotional instructables."  or at least be identified  at the beginning of the instructable as showing how this specific product is the answer to an identified intractable problem.

Homemade player piano

So I got two pianos for free, one in great condidtion other than being out of tune and having a stiff action, and the other, a player, having a badly cracked soundboard and pinblock.  I salvaged the player pneumatics and bellows from the player and managed to mount it upon the other piano.  On each note bellows there were rods that pushed on levers to trip the action of the player piano.  On this one, these levers are about a foot and a half above the bottom of the action, because it is a console piano (shorter).  I've tried linking the bellows to the keys with hooks (which didn't work, it just pulled the keys off the center pivot point) and directly to the action, on the bridle strap hook.  I've tried different strings and two different gauges of wire, but they always seems to stretch, untie or to come unhooked whenever a note is triggered with the player, or with the keys.  If anyone has ideas on how to link the player mechanism to the piano action, any help would be appreciated. Thanks!

All right, let's clear this up: What the hell is inside of a battery?

Really frustrating: I accidentally closed the tab I had been working on for about 15 minutes, so I'll probably be missing a couple of questions I had been meaning to ask.So anyway: When I peel off the outermost metal covering of a zinc-carbon battery, I'm just taking away a protective steel covering, right? When I get rid of that, am I looking at the actual zinc "case?"What is the sticky, black material that surrounds the graphite rod? Is that manganese dioxide? Is manganese dioxide the same thing manganese oxide?Further outwards from the center of the battery, there is another black substance. Is this ammonium chloride?I haven't actually chopped open a carbon-zinc battery all the way yet. Is there a good technique for removing all of the contents?How can I tell the difference between the two black substances? Is the moist, black paste ammonium chloride? If this is so, then why, when I pull the graphite rod out of the battery, is it sometimes coated with a sticky, black substance? Do the substances mix with each other or are both substances sticky and black? Is one a powder?Is it okay to drill through one end of the battery? If I drill into the negative terminal of the battery, what will fall out?Basically, what are the physical properties of all the materials? How can I tell the difference between them?Now: On to alkaline batteries...Both types (carbon-zinc and alkaline) appear to use manganese dioxide. Is this so? On Wikipedia's article on alkaline batteries, manganese dioxide is described as Zn/MnO2, with the two as a sub-script. Does the slash mark mean that zinc and manganese dioxide are interchangeable?What will I find if I open up an alkaline battery? Is it safe to do so? What is a good, safe way to open one up?Are there any particular "fun" applications for these chemicals? Think explodiness ; )I've heard that manganese dioxide can be used to produce oxygen. How do I do this?There might be some yellow tag-box notes on these, pictures. For the context, visit my Instructable on how to make your own carbon arc light. I'm not trying to advertise, I'm just anticipating someone asking about them.

Refrigerator Insulation?

Background: I was looking at Costco and they have their big semi-rugged totes on sale this time of year for like $6! The thing I'm pondering is sticking one in inside another and filling the space between with insulation.  But what to put in between? You're probably thinking what I'm thinking, Pinky:  Spray it full of Great Stuff foam. But then I'm looking at my fridge going... that thing is literally freezing inside and not even cool to the touch on the outside!  What kind of insulation do they use?  I'm guessing something trickier than Great Stuff, what with Energy Star ratings and all.  In short:  What is it and where can I get some!??

How to put a design on a metal cup?

Hey Guys! So I'm a bit new to this (meaning I'm totally new.) So I'm not sure if this question has been asked before,. If it has, please redirect me to it :) I'm looking to 'personalise' a metal traveller's mug, and just metal mugs in general and i was wondering what options are available? I want to go through the options before i pick the method that i'll use. What i want to do exactly is to put my design on the cup permanently. I've seen someone use a vinyl decal and a powder coating machine, but that's pretty expensive to get over here. So what are the other ways i can do that?  I hope someone can shed some light on this for me, Thanks :)

Do you like outdoor games?

Nowadays lots of people are limited to stay in house and play indoor games because of the tech things like ipad, online games. But not long later, you will feel tired of it and go out for some fun.  For different kinds of outdoor games, what do you prefer?  Have you ever try inflatable games. I find it very interesting and exciting.
