Friendship Lamp

You may have seen these online selling for ridiculous priceshttps://www.uncommongoods.com/product/long-distanc...But it occured to me how easy this would probably be on arduino. Do any of you know what would be the bare minimum you would need to get this to work? I would assume you'd need them to connect to wifi, and just send a simple signal but I'm not quite sure how to implement this. Any ideas from those more knowledgeable in the particulars?Thanks,

STATIC LED DISPLAY MESSAGE

My name is Simon Njoroge. I have successfully made a 9(rows) x 24(columns) LED display panel that displays a scrolling message that uses the attached code. The panel consists of course of LEDs, 3 shift registers, a 4017 decade counter together with transistors and resistors. However, I would like the panel to display a static message of a maximum of 7 characters for my project need. Kindly can someone edit the code for me? I followed the instructions from the following site:https://www.instructables.com/id/Make-a-24X6-LED-matrix/

Need help making this bunk bed a reality!

So, I want to do this project with my kids. They’re 5 and 7, and I want to start early in educating them that all this stuff that surrounds them is made by someone, and that someone can be them...Also, they want a bunk bed. :)Take a look at the photo...Can anyone help me turn this picture into a design? I’m pretty handy, but I’d love it if someone with the carpentry-and-CAD skill intersection could take a crack at turning this pic into something I can use...Best,Dutch

How do I put do mp3 playback in a vintage phone please?

This might be a double post by me. sorryWondering if this is possible. I would like to make an old landline vintage style phone work so when I pick up the the earpiece, it automaticaly plays an mp3 through the earpiece, until its set down again. The style of phone I have is the one where the listening piece hangs on the side and the talking piece is part of the phone, the two handed style. Can anyone give some advice on how to do this please or point me in the right direction. Cheers

Opening and closing a small door

I want to build a small cabinet based on the TARDIS. I want the doors to open and close automatically and, of course, make the sound. It will only by 12 or so inches tall so I don't need anything big to do this. Ideally, I'd like to activate it by touch. My first idea was to start with the wiring for The Most Useless Machine and move on from there. Think that's a good start? Any better ideas on how to do it? The full build will be in an instructable.

Tutorial on Nodejs Error Handling

In day to day life, humans have many issues to solve in their life, Right? Yes in the same way in every programming language they have some predefined errors which need to be resolved. Take any programing language you would like to code and ask yourself does your programing language doesn't have Errors - Hmm no right - some of them have the different name, and some have the same name. When we go for Node.js, it’s an environment which has errors in it too. They have predefined errors such as ReferenceError, TypeError, RangeError, and others...etc this all are inherited from the Error class.Note: The ReferenceError and the ReferenceErrors are different but, They perform similar roles, but they belong to different domains, i.e., ReferenceErrors related to Javascript and ReferenceError is related to Node.js.Now, let’s understand the essential categories of errors in Node.js. We can talk about the programmer errors and operational errors. The bugs or issues are dealing with in the program come under programmer errors, Whereas the problems which are happened because of our system may run out of memory which is not a bug this type of errors is known as operational errors. In this tutorial we will learn node.js error handling in detail, So let ’s get started.Short note on Node.js ErrorsWhen we talk about errors, They commonly occur when any syntax has not written in a proper format it throws an exception in the stack with the meaningful words/sentences about an error which is easy to read and understand by a developer. In case the existing error types are not fitting to your project then there another way where you can manually predefined errors and add some relevant information about the error.When you’re creating your own errors you just need to know some prerequisites. The most important one we need to follow is you do not throw string! In javascript, we can throw string but it’s not possible to throw in Node.JS . The reason behind this is when the node.js throw a string we may lose all the stack information and some of the properties that are present in the error object. The second important one you need to know that some of the frameworks are not able to support manually predefined errors in some cases. If still need your own errors you can organize them in a separate module and use it in your application even you can update them in an npm.Node.js Custom Errors in ES5By using the below example, we can create custom errors in ES5 using node.js:Code:function CustomError(note){this.constructor.prototype.__proto__ = Error.prototype;Error.captureStackTrace(this, this.constructor); this.name = this.constructor.name;this.note = note; } throw new CustomError('test');I hope the above code is a straightforward so to understand naturally. I will give you detail information about the custom errors in the below code.Code:Function errorCreation(word, init) { function CustomError(note) { Error.captureStackTrace(this, this.constructor); this.note = note; init && init.apply(this, arguments); } CustomError.prototype = new Error(); CustomError.prototype.word = word; CustomError.prototype.constructor = CustomError; return CustomError; } var OwnError = errorCreation('OwnError', function (word, invalid) { this.word = 'The word ' + word + ' is invalid because of ' + invalid; }); throw new OwnError('run', 'issues');Note: Extending an Error is quite normal in ES6 but, We can’t extend native objects such as Error and Array Class because you may get problems while transpiring from ES6 to ES5. While working with Custom Errors ES5, we should be careful.Node.JS ES6 Custom ErrorsBy using the below example, we can create a custom error in ES6 using node.js:Code:class OwnError extends Error {constructor(note) { super(note); Error.captureStackTrace(this, this.constructor); this.word = this.constructor.word; this.note = note; } } throw new OwnError('run');Is it simple to create, Right? If you look into the program, it is similar to java and c coding. For prototypal inheritance ES6 classes are syntax, Most of the javascript community had a good opinion. However, we can use the instance of an operator and your custom error class on your own.Error Handling for Event Emitters Event Emitters are used to “emit” errors in nodes. Whenever you deal with Streams, It is the default that we need an error handler to handle. In this, you don’t have any information about the error but we get an indication about the error has occurred. While EventEmitters fire an error event by the error code written by yourself.Here is how the Event Emitters works: Whenever an error occurred through the instance of EventEmitter the first action is to emit an error event. While Error events are treated as a special node in this, when there is no listener it takes a default action i.e. to print the following error stack trace and ends the exciting program.Code:const EventEmitter = require('program'); class OwnEmitter extends EventEmitter {} const myemitter = new OwnEmitter(); const logger = console; myemitter.on('myError', (issue) => { logger.myError('Unexpected error on emitter', issue); }); myemitter.emit('myError', new Error('Oh No, You Have A Problem!'));At the time of event fire, If we don’t find an error it shown like the given one it will inform to the Node.JS process, the stack trace is printed and crash it. We can avoid this by observing an uncaughtException event shown to the process object.process.on('uncaughtException', (issue) => { logger.log('Oh No, You Have A Problem!! There was an unknown error', issue); process.exit(1); });Error Handling While using PromisesWhen you're working on Node.js you can see promises everywhere on the node.js, Even you can see a lot of list functions that return promises. Whenever you don’t use proper .catch() you will get an error called unhandledRejection event which will be emitted by the rejection handler. By using below code you can set your listener.process.on('unhandledRejection', function (problem, solution) { logger.error('Unhandled rejection', {problem: problem, solution: solution}) });Node.JS - Errors & Generators When we talk about generators the function executions which are suspended and resumed at the later stages, which are a lightweight coroutine. This is a special generator function by using a keyword yield. By using next() function we can invoke or return an object which has a sum and a variable, where the iteration is not possible to do overridden. At the end of this process, it allows us to write our asynchronous code to be looked like the synchronous code.In this try-catch and throw statement work as grace. Consider the below code.Code:function *generatError() { while (true) { try { var num = yield null; console.log('number', val); } catch (a) {console.log('Here an error been occured', a); } } } var exm= generatError(); exm.next(); exm.throw(new Error('test error'));Here the classic principle error handling is applicable if you have throw exception through the generator and we can catch that error through the try-catch block. Consider the below code.Code:function * generateThrow() { yield 'apples'; throw new Error('No Apples Found'); } try { const pineapple = genThrow(); pineapple.next(); pineapple.next(); } catch (a) { console.log(a); }Errors to Deal with Node.JS ModuleDevelopers like to work with node.js modules they have various utility modules to handle with errors, With the help of packages such as Node.js ecosystem, and node package manager..etc. When the developers deal with custom errors which helps them to concentrate more on analysing.When you have to deal with ES6 errors we have a separate package called as ES6-error and whenever you need to deal with HTTP errors there is a module called HTTP-errors. In Node.JS the most widely used module is VError which gives rebirth for our errors. Node.js has two classes called VError, and WError. When we talk about VError it’s almost the same as classic errors though it allows layer multiple errors and has a meaningful output for the end user.Code:const VError = require('error'); const reqFail = new Error('Error Request failed'); const reqStatus = new VError(reqFail, 'Unexpected status code "?"', '300'); const reqBase = new VError(reqStatus, 'Internal error'); console.error(reqBase); console.info(reqBase.cause().message);In simple words, WErrors are worked as an wrapper for layered errors i.e.VErrors which gives a fast message all about the error information. Once go through the below code for in detail.Code:const VError = require('error').VError; const WError = require('error').WError; const reqFail = new Error('Given Req has been failed'); const reqStatus = new VError(reqFail, 'Unexpected status code "?"', '300'); Const reqErr = new WError(reqStatus, 'Unexpected Internal error has occured'); console.error(reqErr.message); //Internal error: console.info(reqErr.toString());Final WordsErrors are fun to solve but, sometimes it takes you to the peak-leave on frustration and some point of time you knew what was an error and fingered out about an error-handling then you solving time will be less. So, to Learn Node.js error handling I have given an detail information about them in this article once go through it. If you have any queries regarding the topic let me know in the comments section below, I will reply you back as soon as possible.

I need help writing a program on Lego Mindstorms EV3

Whattup y'all, I have a Lego Mindstorms project underway, but I can't figure out how to write the program. If somebody out there who is familiar with programming EV3 could help or give me some tips, that would be great!The project is as follows: I built a start/stop timer for micro drones (i.e., a Tiny Whoop) so you can measure your time around your course. Start the program by pressing the center button on the Smart Brick. The setup measures whether or not the drone is on the starting block with the color sensor (either ambient or reflected light intensity). After the drone leaves the starting block, a timer will be set. The timer stops after the drone hits the stop gate, which presses the touch sensor. The time is then displayed on the screen, where you can view it, and then the program is restarted by pressing the center button again.My problem is that I have no earthly idea of how to make a timer with the EV3 software. If you know how, then screenshot it and send it to me, and you will be rewarded with a great Instructable in the near future!Auf Wedersehen, and thanks in advance!

Wood varnish questions

I want to varnish this birch plywood platform to keep it as waterproof and UV resistant as possible but also keep it as close to it's original pale birch colour as possible. i've never varnished anything before so i've been googling for answers and i'm getting some conflicting information, i've been looking at different clear outdoor varnishes and most claim to protect against UV light and not leave a yellow tint but most reviews say otherwise and some general varnishing info articles claim that clear varnish can't protect against UV at all and i'd need a dark stain which i really don't want. so what can i do to protect the wood against the elements and maintain the colour as much as possible? can i combine varnish with other stuff? i found some clear 'marine varnish' is this heavier duty than normal wood varnish or something?is there an alternative to varnish that will have a similar effect?if i need to modify the platform later, cutting bits out or drilling new holes is it ok to just apply another layer of varnish to reseal it or will it need preparing in some way or some additional step?

Laser Engraving Under Glass.

Just put a video on Youtube about Laser Engraving under glass.A lot of people have made their own Laser Engravers using one method or another.I did the same using old DVD drive mechanism's a couple of Easydrivers an Arduino UNO and a 2 Watt Laser Diode and a Constant Current Laser Driver with TTL / PWM.Arduino has GRBL 1.1f loaded on to it and I use LaserGRBL (free program) to do the image settings, generate the GCode and burn the image.It's a good little machine, although the workpiece size is only 39mm x 39mm max.Eventually I'll build a bigger machine, but for now it does what I want it to do.Recently I removed the fan that blows the smoke away because it was whining a bit and getting on my nerves.So instead I tried using a piece of glass cut from an old flatbed scanner, on top of the workpiece.Seems to be good quality clear glass, I suppose it had to be if it was in a scanner.This stops the Laser from producing smoke and also soot.It does however produce a sticky residue on the back of the glass, but that can be cleaned off in soapy water.I was quite surprised at the results.Laser Engraving Under Glass.

Am I missing something or is this battery charger just insane?

I bought this cheap charger that charges 2 Li-ion 18650 on eBay: https://www.ebay.com/itm/182586752606?ssPageName=S...But it charges them in PARALLEL!So if I put charge two batteries that have a different voltage, the charger will drain one and charge the other one at a pretty high current.If one battery is older, or has a different chemistry, it must not healthy to charge both.If I decide to charge only one, will it push too much current into it?If someone accidentally inserts one in reverse...If you want to charge 2 batteries that are exactly the same, make the charger a built-in feature in the device that uses the batteries, why disconnect them. Used batteries will always have a different voltage!I used to charge them with this cheaper charger, but I recently found out it charges them to 4.30V sometimes, and I want to be able to charge more than one at once...I don't care about charge time since I have a bunch of batteries always ready to use, prefer not to have our house burn down, but don't want to spend too much $ on a charger. Watt do you think of these? I don't want to pay 8x the price to have a charger tell me the voltage and be limited by USB cable's current...https://www.ebay.com/itm/VONTAR-LCD-Intelligent-Ba... ("smartest" & most expensive. Still, only tells the voltage)https://www.ebay.com/itm/Liitokala-Lii-202-18650-2... (confusing)https://www.ebay.com/itm/4-Slot-Smart-Battery-Char... (not "smart" but seems the best IMO)https://www.ebay.com/itm/50-1000MA-Lithium-li-ion-... (Hmmm...)Because we all know what can happen with an 18650 gets angry... Though I have used this charger to charge 15 y/o 19650s that were 0V, back to normal and they are like new now...

Pyrolixer - can you help me figure out what it is?

I need to figure out the actual name of something I bought years ago under the name of "Pyrolixer" for pyro-effects (in Germany). I am also curious as to whether you could diy it.Let me describe what this is about: a liquid that you apply to paper and let dry. When you set fire to that area, it will smolder away, but only where you applied the liquid. From what I gather, it is used for magic tricks and similar effects. In addition to have paper smolder slowly, you can use it to reveal a message by letting it burn away specific areas.Can anyone help me out? "Pyrolixer" does not appear to be a good search term, and thus probably now the English/original/technical name for this. Any feedback is appreciated, and ideas about how to make your own even more so!Thank you!

Search problem.

I wrote an Instructable on how to use the Verowire technique to make circuit boards. Rather oddly a search for "Verowire" does not find it. It finds other things which do not have "Verowire" in the title, but not the article that does. So perhaps I didn't need to bother writing the article, perhaps my search to see if it had already been written wasn't as conclusive as I thought.

I'm having trouble with my sketch regarding how to code , my stepper motor traveling to a limit switch then reversing and accelerating to another limit switch.

I'm having trouble coding at a point, I built an Equatorial Platform for my telescope so I can track the stars.I have a Nema 23 stepper( 1.8 * step, 200 steps per rev.) motor with an Arduino and a Easy Driver for my micro controller. My problem when I make my sketch I have the stepper motor running at 92- 104 RPM with a potentiometer to fine adjust, at this point when my platform hits a limit switch then I want to reverse the motor and accelerate it to 2000 RPM then decelerate to 25 RPM before the platform hits an other limit switch, then start the process over.How do I incorporate accelerating coding that to a certain point then decelerate motor before it hits the other limit switch. Do I need to find some timing coding ( for some length of time), before I want the motor to decelerate to hit the second switch. I don't want the motor running at 2000PM to hit the limit switch, I want it to decelerate before the limit switch. then reverse the motor again to 92 - 104 RPM. I'm a novice at coding with little electrical background. Your assistance is greatly appreciated. Jack Brockhurst e-mail jacam9803@yahoo.com

Hi, I'm a student and I'm looking for an experienced partner for help with my project :)

Hi, my name's Chaitra and i'm a 17 year old product design student in the UK, doing A level product design.As part of our coursework, we are required to find and interact with an "expert", a person with a good level of understanding of product development and technology.As you might expect, it's quite hard to find someone like this at random, which i why I've come here to see if anyone is willing to collaborate with me :)My coursework will be based on air conditioning, specifically regulating and purifying air conditions during sleep, so it will involve a good amount of electronics and physical design. As the "expert" of my project, we might exchange ideas and offer suggestions to improve the project, and even maybe advice on the best ways to manufacture the final prototype for assessment. You can be as involved as you want to be honest, I appreciate that everyone is busy so you won't be able to commit a huge amount of time to this, but maybe exchanging emails around once a month? I might send over some sketches / cad files over email for you to evaluate and suggest some improvements or ideas on, nothing more than that.If you're willing to help, please answer this topic so we can work something out! Thanks a lot :)PS. this is my first time using instructables, if I've submitted in this wrong place or something, please let me know

I need help connecting 2 solar panels in paralel

Hi,I'm new to Electronics but I love solar panels and hiking.S, I bought 2 of these:https://www.tomtop.com/p-l1613.htmland one of this:https://www.ebay.com/itm/Dual-USB-Solar-Boost-DC-D...and I connected them. I cut 2 USB Cables, connected + with + and - with - from each Cable and connected it to the DC-DC booster. The amperage is not doubled and the output Volts are lower than 5V which should be the constant output of the booster. The panels were solar oriented and the output was only 0.02 A with Bright enough sun from those 2 solar panels. The panels separately work fine, it is only when I connect them to the booster that they act weird.Is the problem in booster or is it me doing something wrong?Thank you!

An awesome website I found for sharing the tools you use in your Instructables (or for anything else!)

I recently found a free website called Kit.com, and as the name implies, it's a website for making kits of the stuff you like and useSo far, I've made a bunch of different kits such as " Dremels & Rotary Tools: All of The Accessories You Need" " My MUST Have Workshop Tools I WISH I Would've Bought Earlier!" (And several others that are organized on my Kit profile page)I think it's a pretty cool website, and encourage everyone to make their own kits of the tools and stuff they use in their projects! If you make your own kits, link them to your Instructables profile page (Like I did with Linktree), and post a comment below so can all see what you use and waste more money on tools we're sure we need! :)They also have an option for embedding the kit in a website which looks really nice (see this, though when I tried it once it looked a bit different), but unfortunately Instructables doesn't support it... (hint-hint!)You can also create an affiliate code, so when people buy through the links, you earn a few percent of the sale, which is pretty cool too!Maybe unrelated, Kit was just acquired by Patreon so if you read this in the future it might not be free. I have no idea. Also, if you're an SEO genius you need to tell me how to make it so my kits rank on Google!Post a comment if you make one!

The indestructable bike lock! ...Idea

The indestructable bike lock: the forum topic that was posted undeniably just to annoy the future patenters!So I had this weird idea for a product come out of nowhere. Y'know how aluminum is supposed to make cutting wheels on an angle grinder gum up, stick, and shatter - when trying to cut it, that is? I was wondering, what if a company engineered a special type of aluminum alloy or a similar material that would do just that: gum up abrasive cutting wheels and make them stick/bind and shatter. Then like with layers of plywood, it would be sandwiched together with hardened steel, in the shape of a U-lock bike lock, making it: Impossible to cut through with a hacksaw, reciprocating saw, TCT bladed portaband , because it's hardened and would wreck the teeth. Impossible to cut through with an angle grinder or rotary tool with an abrasive wheel because the aluminum would gum it up. Impossible to cut through it with bolt cutters - obviously... Impossible to freeze it with freezing gas? I don't know. I heard that's what thieves do. Maybe that aluminum alloy would be a super-insulator and wouldn't allow the hardened steel layer to freeze and become more brittle?I think it might just be invincible until the portable cordless battery powered waterjet is invented!Thoughts?

Dogwoods

Hi, I purchased a few dogwoods, pink and white ones, the tags fell down from the pot and now I don't know who is who. There is any way to identify which one is the white one and which one is the pink one? They are around 12"

We have an FoodDSaver QuickStart V825/845 Game Saver Sport vacuum sealer that will suck the air out but will not seal. I was wondering if it could be the heating element gone bad???? Tell me how to check it and how to fix it. Thanks in advance. My email is; fed1@farmerstel.com.

Dual timer switch

Is there a commercial dual timer switch that the first timer can be set for longer duration like hourly or half hourly and then switch on another timer that run in seconds. Or is there a DIY solution? Eg. Turning on a water sprayer every 2 hours for 10 seconds. I need a timer that run from the mains.
