Let us assemble power distribution switches at home together.

I am an electronic engineer in the field of power distribution switches. In recent days, I am prepared to make a project for power distribution switches at home together.  The project begins now: Home decoration, the concern of hydropower indispensable. The laying of the home circuit is a crucial link, the home distribution box installation involves the safety of home appliances. Therefore, I specifically summarise the home distribution box installation knowledge, as well as home distribution box wiring diagram to make the relevant finishing, for everyone to take precautions, the home distribution box has a clear understanding. Home distribution switch installation points 1, Household distribution switch sub-metal shell and plastic shell two, there are two kinds of mounted and concealed, the box must be intact. 2, The household distribution switch of the cabinet wiring assembly should be set up to zero line, to protect the ground wire, phase line, and to be intact, with good insulation. 3, The installation of air switch seat should be clean and there is enough space, should be installed in the dry, ventilated parts, and no obstruction, easy to use. Never install the distribution box in the box to prevent fire. 4, The household distribution switch should not be installed too high, the general installation of the elevation of 1.8 meters, in order to operate; into the distribution switch of the electric tube must be fixed with a lock nut. 5, If the household distribution switch to be open, the edge of the hole to be smooth, smooth, distribution box buried in the wall should be vertical, horizontal, edge left 5 to 6 mm gap, distribution box wiring Should be rules, neat, the terminal screws must be tightened. 6, The loop into the line must be sufficient length, no joints, after installation marked the name of the use of the circuit, the installation of household distribution box to be completed after the removal of the distribution box residue. How to assemble power distribution switches at home ? 1, The installation of electrical box, distribution box installed on the wall, should be used bolts (expansion bolts) fixed, bolt length is generally buried depth (75 ~ 150mm), the thickness of the box floor, nuts and washers Of the sum of the thickness, plus about 5mm of the "margin". For smaller distribution boxes, it is also possible to embed a good brick at the installation site (in the form of a distribution box or a panel mounting hole) and then use wood screws to secure the distribution box or power distribution board. 2, Dark assembly distribution box, distribution box embedded in the wall installation, in the wall when the hole should be reserved than the length and width of the distribution box about 20mm, the depth of the distribution of the thickness of the distribution box with the wall Plaster thickness. In the masonry distribution box, the box and the wall filled with concrete can be fixed to the box live 3, The distribution box should be installed firmly, horizontal and vertical, vertical deviation should not be greater than 3mm; concealed, the distribution box should be around the gap, the edge of the panel should be close to the wall, the box and the building, Part should be coated with anti-corrosion paint. 4, The distribution box installed in the spiral fuse, the power cord should be connected to the middle of the terminal contact, the load line should be connected to the threaded terminal. In this way, in the loading and unloading fuse will not be electric shock. Porcelain plug-in fuses should be mounted vertically. 5, The distribution box of AC, DC or different voltage levels of power, should have a clear sign. Lighting line, should be set to zero line (N line) and protect the zero line (PE line) bus, zero line and protection of the zero line should be connected to the bus, not twisted, should be numbered. 6, The wire leads to the panel, the panel line hole should be smooth without burrs, metal panels should be installed insulation protective cover. Metal shell distribution box shell must be reliable grounding (then zero). Ps: Excuse me if I was wrong in words or expressions as I am a green hand in the field of power distribution switches. I need continual learnings. What is your idea ? Do you agree with my ideas ? Any of your ideas would be highly appreciated. May someone would like to help ? thanks in advance.

About RN-42 bluetooth (with two arduino MICRO and one laptop)

Hi, there. I have a question about RN-42 bluetooth module. I want to make a bluetooth HID device (keyboard and mouse) and ,because of my direction of team project, it has two pieces. One arduino MICRO (using RN-42) is going to be master and the other MICRO (using HC-05) is going to be slave. Actually their roles can be changed! The goal is to connect RN-42 to my laptop while RN-42 is also connected to HC-05 and use this as a bluetooth keyboard. Now, Is it possible that RN-42 module has multiple connections?

D3CRYPT3D won SXSW Interactive Innovation Award for Privacy & Security

Hey everyone! For a long time, being a modeler and working in the industry, I have always felt that Modelers get the short end of the stick.  Things get re textured, models get hijacked and studios just kind of store models and stock pile them up. Some people will even resell models that don't belong to them. I used to see it all the time. Well, my crew and I came out with a software that enables you to share and collaborate on your 3D files securely. We won the SXSW Innovation Award for Privacy & Security last month and just released our beta this week.  We would love for you all to try it out and give us your feedback so that we can make the best product possible.  If you are interested, here is the link to download -   www.d3crypt3d.net/downloadnow/ Thank you!

I though I might post about this new project we've put together. Crazy Circuits Kickstarter We've developed a LEGO based electronics system.  More or less, parts on circuit boards with big holes.  It works great for creating LEGO robotics and electronics projects.  From simple to advanced. We'll be posting several instructables on how to use these, as well as projects you can build with them.  (Or without them.  They're just simple parts on our custom PCBs.)

Hidden dangers of receips and dockets printed on thermal paper

Ever wondered how these thermal papers for your fax machine or supermarket docket work? Nothing that is printed by fast machines for you these days uses ink when it comes to cheaply producing a parking docket for example. If you played around with these papers you already know they turn black when you apply heat. A soldering iron at low heat makes a nice pencil on them... But what if you pet or kid loves to play with these papers? Often they like do just jast with the receipt for your fast food if found inside the bag ;) Most people would not consider a piece of paper as a health risk, but for thermal paper this can often be a different story. A lot of these papers still use bisphenol in one form or the other to develop the ink from crystal clear to black. Feel free to read up on it on Wikipedia - I recommend it! They also have more info on the thermal paper itself, including alternatives to bisphenol. Although recent studies are in favour of the thermal paper, when handled correctly some also show an increased risk for those dealing with a lot of paper - like the people working at cash registers in a really busy shop. Bisphenol can get into the body through the skin and by ingestion - for example when your kid tries to chew on it. As noone really knows where the paper you got came from it is a guessing game to figure out if it is free of harmful chemicals... So the best option is to avoid exposure when possible. If you know your kids or pets might to try eating some paper then make sure you don't leave any thermal paper around where they could reach it. But there is good news too as more and more countries try to set standards for thermal paper in regards to harmful chemical levels and protective coatings. Cheap paper for almost any priter out there can always be ordered from asia to avoid higher costs of local and safe paper though...

Computer Science Project: Automated Follow Spot

Hi all!  This is my first post on instructables. I've been using this website for years to facilitate many projects, however this is the first time I'll actually be posting any questions of my own on the forums! Exciting! I'll cut to the chase, for my computer science A - Level I am required to complete a programming project, complex enough to get me a good grade, but feasible enough to actually complete! I decided to take a more practical approach and have arrived at the decision to make a robot of some kind. As I'm heavily involved with the drama department in the school I wanted to create something that could also help them. I decided upon an automated device that can use some form of trilateration to determine the position of a person on stage and then position a light to light them up. For those who have more experience in the world of technical theatre, I'm talking about an Automated follow spot. For those who don't here is a link to a wiki page.    The premise being that a person normally has to control a follow spot, pointing it at the person (or people) on stage, to light them up. An issue we have is that sometimes we don't have enough stage hands to operate the follow spots, which means they're left by the wayside. My idea will negate the need to have a human operator and should simply follow the person around the stage. The main idea at the moment is to use a single long range bluetooth transmitter, attached to a wristband (which would be worn by the actor/actress) and have three long range receivers, which in conjunction can trilaterate the position of the actor/actress and position the light to illuminate them. I have a couple of  questions: 1. Firstly, is this feasible? This is a project that I really want to see through to fruition, especially as it will count towards my final A-level. For someone of my level of knowledge/experience - is this possible? 2. What would be the best method for transmitting the radio signal? Bluetooth sprung to mind instantly, but is this the best option? I know there might be potential pitfalls in that a theatre is full of metal items and interfering signals that could disrupt this, so are there any better alternatives? I know there are only two questions for now, but I've only just started the design of the project. I'm sure when I get seriously into it I'll have many many more, but I trust that the good people of instructables will be able to provide some help! Thanks again, Eliot C-Hill

Enforceability of CC "Non-Commercial" license?

Update: I was able to resolve this issue with Jameco and I now earn a commission on the kit sales. Original post below. -------------------- I'm not sure if this is the right forum to post this, and I realize most responses will probably start with "I am not a lawyer, but...", but I figured it's worth asking. I publish all my Instructables under the CC Attribution-NonCommercial-ShareAlike license: http://creativecommons.org/licenses/by-nc-sa/2.5/ http://creativecommons.org/licenses/by-nc-sa/2.5/legalcode What I had in mind was that I didn't want people trying to sell the content - putting my Instructables in a book and selling it, or behind a pay wall on the internet or whatever (I realize the odds of that happening are probably slim). I figured the odds of anyone actually selling a product based on one of my Instructables were vanishingly small. However, it turns out that my most popular Instructable: https://www.instructables.com/id/Arduino-controlled-RGB-LED-Infinity-Mirror/ is now the basis for an Infinity Mirror kit sold by Jameco Electronics: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2215380_-1 It looks like this was a project by one of their summer interns, who did a "step-by-step guide" (which DOES link to my Instructable as the original source) here: http://www.jameco.com/Jameco/workshop/JamecoBuilds/infinity-mirror.html To complicate things a bit, Jameco as a feature called "Club Jameco" where you can design electronics projects (similar to Instructables) with a set bill of materials, and if it's popular enough they will sell it as a kit and give you a comission: http://clubjameco.com/ I contacted Jameco to let them know that technically I'd published the project under a non-commercial license, so they probably shouldn't have done that without consulting with me (in a very cordial manner, not threatening to sue or anything). Their response was that they thought the intern's work was "different" enough and that she put enough of her own work into the project that it constituted a different product, which I strongly disagree with (the only circuit diagram in her written directions is from my Instructable - all she really did was create a BOM using Jameco parts instead of SparkFun). I would have liked to make this my own Club Jameco project so I could earn commission, but they said they wouldn't want to sell duplicate kits like that. Realistically, I doubt I'm missing out on huge amounts of cash here (the kits retail for $80 and commission is 10% or so), so I'm in no hurry to go hire a lawyer. I'm just curious about the enforceability of Creative Commons licenses in general. Do I have the right to just tell them "Hey, you actually can't do that, because the license says so?" In theory, would I actually need to hire a lawyer and send them some sort of scary-looking cease-and-desist letter? So again, I know most Instructables users probably can't give actual legal advice...just curious if anyone else has had a similar experience. I'm sure content gets ripped off without attribution quite a bit, violating the "Attribution" and "Share-Alike" clauses of the CC license.

BooHoo Previous Comment Persons

​Hello,  Reading some of instructables comments necessitates me to comment on you! I find Instructables as having interesting content which has appeal to a variety of people  regardless of their mental capacities.  Items portrayed on the site are creations of every class of people. Having a special talent, each of them feeling a little pride, bravely present their subject matter with instructions,  pictures, videos, FAQ, help? and their names are printed on the website. Speaking to the big shots who know it all.  This is not a specific website geared to the most intelligent humans like yourselves.  If it looks like a project for a 5 year old---it probably is! Clever mistake observers, nice of you to point it out.  Did you fail at the project?  Did you do something wrong?  If after you check yourself and it happens that you are right.  Why not have a little consideration, call or email Instructables, insuring the situation is clarified by the important people involved.  You would be saving the embarrassment, ridicule and self-esteem of an individual, or didn't you think of that? Instructables your website is unique, interesting, educational, subject matter is something about anything! The site has helped me babysit, fight boredom, release stress and laugh hysterically!

Is Ikea the only place that recycles incandescent light bulbs as well?

CFL bulbs need to be recycled properly due to mercury content, and there are many places: Park districts, hardware stores, Ikea, etc. that recycle CFL bulbs. However, I haven't found any place that recycles incandescent bulbs, I searched online and they say, they don't contain any toxic chemicals and can be thrown in trash and not curbside recycling. However can't the glass be reused to make new bulbs? I am sure they can reuse the glass, and the filament is probably too hard to recycle but the glass could be. I know Ikea recycles incandescent bulbs as well, but why aren't there any other companies that do? Also LED bulbs, I guess dead LED bulbs can either be returned to manufacturer if it has warranty, or in electronic recycle.

Interesting TAP handle tech question \ quest.

Here's a weird one for  you guys. I recently bought a Beer tap handle and noticed that it had an insert that had some LEDs on it. Cool. The problem is that the LEDs don't light (beyond a tiny SMD red LED heartbeat). I found a small button that when depressed seems to trigger a test. Bright white LEDs on the top and bottom flash to illumnnate the top of the tap (either a clear baseball or FIFA tap topper) as well as the body. It's hollow plastic so it briefly glows. The problem is that I can't figure out how to light the things beyond the test (for which you have to remove it from the handle). The guy who sold it to me said they've sold lots like this and could never figure it out. I figured light sensor? nope. Tilt sensor so it'll flash when you pour a beer. Nope. I broke out  my loupe and noticed a funky thing on the circuit board that looked like it had an antenna. It was an Anaren A1101R09A. This thing is a radio tranceiver!  That tells me there was a remote with it that was lost in the few days after they bar got their new tap handle. Does that sound right? If so I was wondering where I could get or build another. I could put together some other LED solution, but I'd love to get this to work. HEre's a pic of the tap handle and the insert laying on it's side. The right side is the up side with the transceiver. It's blue if you look closely. Not sure I'll get a solution, but there's some clever people here, so you never know. Thanks for reading.

How to Make a Constant Current Lithium Ion Charger

Hi Guys! I have a bunch of 18650 lithium ion batteries that can handle a charge rate of 5C. Each one is 3,000 milli-amp hours, and I would like to build a charger for them as my project. I understand the mechanics of charging lithium ion batteries, and that they need to be charged at a constant current up until that current reaches 4.2 volts, than switch over to constant voltage. The constant voltage charging makes up about 20% of the battery capacity, and I am willing to forgo that amount. What I am trying to build is a constant current charger for it that would  charge at a current of 1C, and shut off when it reaches 4.2 volts, and I would like some help as to how I would do this. I was thinking that I would have some sort of current source that supplied 3 amps and then have a relay that would shut off the current as soon as a voltage detector reached 4.2. I do not know much about current sources, so I am asking here for some help. Thank You for Your Help!

Suggestions for painting an Invicta diving case?

So I've got some Instructables in mind for painting a Nerf Maverick. (Wait, you said you were painting an Invicta diving case...) Yes, you're right. The case will be a custom painted case to house a custom painted Nerf Maverick for a Christmas present. However, I have some questions about how to paint it. The case has a rough outside made from what I suspect to be high-impact plastic. The inside is smooth plastic with removable foam inserts and a rubber gasket seal. I know I will have to sand the inside to make the paint stick, but my question is if the outside is already a rough textured plastic, will I need to sand it as well? Also, what paints and finishes do you suggest for painting this case?  The Invicta logo on the back will need to be sanded (although I suppose I could leave it since they manufactured the case). The picture shows what my case looks like, minus the graffiti image. Thanks in advance, and God Bless!

The profile page is near to many of your hearts as the front door to your substantial investments in Instructables, and while some have found these changes disturbing, we believe that they're very much in the community's best interests. I wanted to reach out just to let you know that we have given the new design a great deal of thought and attention, and to share with you some of the reasons behind the changes. First, to clear up some ambiguity about the current state of affairs: The public member profile is stage one of two major changes to the site that will work together. Stage two, which is well underway but not released yet, involves the private profile page (currently the "you" page) and will make access to aspects of your presence on the site much more accessible. Full lists of your own content will soon be available on a full-featured (and much more beautiful) private view of the member page; meanwhile, this content is all available in the "you" section. So the sense that your own content has gone missing is temporary. Second, the High-Level Goals: Clearer, more accessible design. Our old member page, say what you will, had a lot of buttons and options. On the whole, we know that most people don't take the trouble to drill down into the various categories. We want to help you all build large audiences of new appreciators, and while an infinitely detailed catalog of an author's content is appropriate for some, the breadth of activity on Instructables can make it difficult for new users encountering the site for the first time to understand what Instructables is about. Fundamentally this is what the new design is for: to help people understand, at a glance, what a given author is up to on Instructables. Highlighting Engagement vs Cataloguing Activity. Different people interact with Instructables in different ways, but our member page has never reflected this subtlety. It has always presented the most recent Instructables and comments, even for authors who contribute exclusively to the forums, or through favoriting and following other users. We felt that your activity on Instructables should be presented front and center, because it more evenly describes the way in which you participate in the community. Many members participating in this very discussion have benefitted from this choice, even as they challenge it. Forum posts used to live buried under a tab on the left; now, the contribution of a forum topic can appear right at the top if that's how the author participates in the community. We wanted to see how authors engage, and we felt it was ultimately more important than being able to drill through every piece of historical content hierarchically. Audience vs Self. The old profile page served "my view of me" and "my audience's view of me" somewhat evenly. With the changes we've made, and the changes in the pipeline, we're taking a stance. The public page is for my audience, the private page is for me. We're confident the new design better serves authors' audiences, even if it has some weaknesses for the author's own view. The author-centric side is coming, please hang in there! Surfacing Older Content. At HQ, we have frequent discussions about the "evergreen-ness" of the Instructables authors post. A great project from 2009 is still a great project, even though the wider internet has a strong preference for "new" over "good". But it's a struggle for us: we can't put every good project on the homepage forever, or new projects wouldn't have a chance. So we have to strike a balance. The new member page helps in this regard: if your old-but-awesome project still gets some attention and activity, it'll show up in your timeline as people favoriting the old project. So your profile becomes a place of discovery, where I can see "whoa, look at that cool thing that this person made 3 years ago!". Previously, the old project would have been buried under several clicks from the landing page, generating almost zero traffic. Add to that the new ability to select "top projects", and you can see that we're trying to help you keep your best projects in the limelight. See new features below. Third, New Features to Help Authors: Top-Five Projects. DIY Projects are at the core of the Instructables experience, and we listened to authors who make different kinds of things, but want to treat their Instructables Profile like a Portfolio. Randofo is one of the community's best-known and prolific Arduino Gurus, but it's a fact that an Arduino Project of his is a much bigger time investment than some of his smaller food projects. In fact, did you know that he's authored 38 food projects? Now, randofo has the opportunity to present his most-relevant work first, rather than leaving it to his audience to figure out. Right now, he seems to be all about Halloween. Activity Feed. Love it or hate it, it's here to stay. We felt that having an activity feed on the member page was the most effective way to answer the most important question for a member page to answer: How does this member participate in the community? While that information was certainly available in the old layout, divining it required an audience member to click through all the tabs, reading every piece of content to completion. There was nothing "glanceable" about the information architecture, except perhaps the achievements (which we've kept). We believe that the activity feed, with the "top Instructables" feature in particular, makes it much easier to determine at a glance how a member participates. Fourth, It's a Living Document: We're watching your comments and feedback closely, and I expect that you'll see some pieces that you're missing return. I can't comment on specifics right now, but I know there are some statistics and counters that may have value. We agree, and we'll respond. But there was a whole lot of "extra" information on the page to begin with, and we wanted to start over as cleanly as possible. UX & Bugs. With a big feature like this, there are bound to be growing pains. Hopefully, you've already seen some improvement with regard to the delay in setting your "top Instructables" and having those reflected on your page. There's still a little blip, but it's down to about 10 seconds now, vs the 20 minutes when we first released it. Sorry about that! We'll also be looking carefully at how the page looks, making sure that we aggregate activity events such that no one event type (ahem, favorites!) takes over, etc. That's all for now. Hope having a little context helps put the changes in context. If it can't bring everyone onto the same page, we at least hope that it'll make them a little less out-of-the-blue. Thank you to you all who have written your comments, and who care so deeply for the community of Instructables!

The Pi Day Challenge Says "Judging ends midnight April 11, 2016"

What the heck?  Midnight April 11 has most definitely happened(judging by how it's April 12).  Can someone explain why it's...  Delayed?

Contests are becoming too specialized

Lately I've been seeing more and more contests which require expensive, specialized tools (mostly 3D printers) in order for you to make something that is eligible. I wish we would have less of this type of contest, or at least have people utilize tools other than 3D printers. How about a milling/turning contest instead of endless 3D printing-related contests? I'm just worried that many of the contests are inaccessible to the average instructables user, and also getting a bit bored of contests which involve 3D printers.

Connecting small generators in series?

Hi all,I'd like to make a bunch of small generators, like Pleech turbines, for example. Each one might only be producing a couple volts and however much power. What is the best way to connect them together to get their combined power?I was thinking that I could just give each generator its own rectifier, and then connect everything together in series. Would that be efficient?My circuitry understanding is a little limited, so a simple solution that is 90% efficient may be better than a complicated solution that's 100% efficient.... :)Thanks for any suggestions!

Resource: instructable monitor bot command line app

Hi all, If you are looking for a way to be notified when one of your instructables gets a spike in more views, I wrote couple different python command line apps for that exact purpose. The first displays a visual notification, speaks and announcement, and plays a beep whenever your tutorial gets X more views. You can customize X. The second uses email notifications instead of text to speech. The third command line app lets you customize the notification ringtone. Hope you find this useful! There'a a full tutorial here:  https://www.instructables.com/id/Instructable-Hit-Announcer-Bot/

Cathode Ray Tube and Cloud Chamber Combined - Possible?

Is it possible to build a cathode ray tube and observe the path of electrons in a combined (or linked) cloud chamber? I would want to apply a uniform magnetic field to the cloud chamber but not the CRT so that electrons travel in a straight line into the chamber and are subsequently deflected. Oh, and ideally using materials that were available in 1917! Thanks in advance.

Cooling Fan Timer Circuit

I'm tying to setup a 12 volt 2.5 amp injector cooling fan in a car and I want the fan to turn on for X minutes right after the ignition key is OFF. I was looking at this programmable relay - https://www.amazon.com/Miniature-cycling-Cycling-Industrial-control/dp/B015Z2EQCU/ref=pd_lutyp_simh_1_3?_encoding=UTF8&pd;_rd_i=B015Z2EQCU&pd;_rd_r=5202NNSP2PM3EE5DZVTA&pd;_rd_w=SKMnb&pd;_rd_wg=rJ4Td&psc;=1&refRID;=5202NNSP2PM3EE5DZVTA Here is the website for that relay with instruction manual - http://www.3rdbrakeflasher.com/ I'm not sure if I need another relay and hook to 87a or if there is a better circuit I can make.

Potentiometer knob collet work??

I have a 6.35mm smooth shaft Potentiometer and looking for a knob to go onto it. I've seen the set/grub screw type, i get how they work but worried about slipping. Also seen the collet type but not to sure how they clench down on the shaft. The shaft isn't threaded, as just a groove running along the top of it. Would it work like a conventional collet from say a dremmel tool?

PDF Doesn't Update to Reflect Project Changes

I made several edits to an Instructable yesterday and the PDF file doesn't show any of those edits. I would guess that the PDF file is cached, but that cache should be cleared after edits are made so that premium users can download a PDF that reflects the current version.

Help Needed, 3D Printing Via Electroplating

A few years ago I saw a 3D printer that printed using UV reactive resin and a DLP projector and I obviously started thinking about ways to make this for myself. Recently I have been entertaining the idea of repurposing the old CRT technology with phosphors that produce UV light to replace expensive DLP projectors but I couldn't think of an easy way to do that. I was fiddling with various ways of repurposing one of my old CRT monitors when I had a decent idea. Instead of converting electron beams into light to harden resin why don't we harness the electron beams for the purpose of electroplating! Instead of resin we could use an ion solution and build models out of metal! Of course we would still need to replace the phosphors embedded glass screen with a conductive plate to serve as a non-consumable anode. Unfortunately I do not have the time or resources to do this myself so I wanted to post this to the Instructables Community and see If anyone felt this was a worthwhile project.  Please let me know what you think of the idea! I would love to see this turn into an actual project.

sheet foam shock absorber

Im making a trailer for a longboard (skateboard) with a speaker setup on it weighing around 20kg, the speaker im using for it is a fairly durable plastic mobile DJ style speaker but even so i'll be pulling it around over potentially rough tarmac/asphalt surfaces on a trailer made from skateboard parts so could a couple of small sections of foam sheet sandwiched between skateboard truck baseplates and the deck offer adequate shock absorption? i have squishy 1.5cm thick yoga mat foam or firmer 1cm thick sound proofing foam to choose from...
