I wish to know how am i able to write a program which i could control the water spraying, brushing and drying by using arduino. My project is to use a laser pointer which will send the signal to the LDR and it will trigger the water to spray, brush and dry the toy car on the conveyor belt. Can anyone help me?? I'm a diploma student, and my supervisor is a mad man which who asked me to do such project which he doesn't know either.

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

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/

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?

Copying and rehash are not things often regarded as good for do-it-yourself communities, yet Instructables is currently quite accepting of things that would fit under this umbrella and in some cases even sponsor it. I hope to convince the administrators that new rules need to come into play--particularly with regard to competitions. I'll discuss why unoriginal projects are a problem, lay out the causes of this and present some solutions that the administration could pursue. Copying is a problem for Instructables because making your own example of someone else's creation with no alterations does not advance development at all. In many cases, these copies even infringe on copyrights. In competitions, such as ones on Instructables, copied projects can become popular and even eclipse original designs; this discourages originality. An author might ask himself why he should bother investing time researching and developing a project when he could just as easily locate an existing design and copy it instead. In many cases, the causes of copying can be innocent, such as when a child who posts his friend's favorite paper airplane design (which actually originates out of a copyrighted book, for instance). While innocent, this action still proves unhealthy to the DIY community. There are also less innocent types of copying as well; such as those who knowingly steal creations and post photographs or links to media of creations not of their own design. While this latter type is less prevalent on Instructables than places like YouTube, it still occurs due to embedding. To discourage unoriginality and encourage advancement, Instructables staff should make a few changes to how entries are looked at as far as appropriateness goes, as well as what gets featured or judged a winner in contests. Projects that are not original should be recognized as such. It might be appropriate to outright disqualify an entry or issue it a penalty or rank reduction in judging. It is not advisable to feature unoriginal designs. These sort of steps could encourage people to contribute rather than copy. I hope I have inspired thought in others regarding this. I have talked about the problems of copying, why it happens and how it might be addressed--hopefully it is.

At this one site I haunt now and then, looking for new science toys and things to hack, I came across this little item called a Euler's Disk. I am assuming at this point, that there is quite a bit of specificity in the way this needs to be made so that it works, thus the $25 price tag. Anyone have any information (not contained in the ad) on this? It'd be most appreciated.

The other day I wanted to post an 'I made it', well because I made it. But the function is not working. I tried it in Google Chrome, Google Chrome Incognito, Microsoft Edge, none worked. Cleared my browser, tried again, still no luck. Tried it on my phone (android 8.0) in Google Chrome, didn't work either.I've attached a photo of how it looks on the website. I'm able to press the 'I made it' button. Then the options 'add tip', 'ask question', 'post comment', etc. pop up. When I click 'post comment' (or another option) however, the area in where you should type doesn't appear. I also cannot add an image, because that button cannot be pressed.Hopefully you are able to help me with this.Ruud

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.

Hi there. Very simple question from an idiot. I'm making a mini puppet of robby the robot from forbidden planet. for the mouth i've a simple set of cheap battery powered leds. There are 20 leds and i've got them in 2 rows of 10. I want to be able to operate them in a really simple way so that the top row comes on or the bottom row or both on to simulate robby speaking. My plan is to split the set of lights into 2 sets of 10 and have each on a circuit where i was going to make a switch for each set that is simply something you press down. Then having the 2 switches next to one another so you can press 1 or the other or both at once simply with your thumb, and i'm thinking of simply using a coke tin aluminium to complete each circuit. I can imagine someone who actually knows what they are doing thinking, this guy knows nothing! and they'd be right! but any tips or alternative methods or even confirming this plan will work are much appreaciated, thankyou.

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!

I am looking for a way to make a wearable (bracelet or hanger) that will vibrate when I send a signal (i.e. text message?). It's intended use is to alert players to certain pre arranged situations in a game. As coach I can not always reach my players across the field by voice so I want to send an alert signal. Also this is more discreet. A smart watch is to big and volnurable. Bluetooth does not have the range so I am thinking gsm. Any suggestions on how to build such a device?

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.

Hello Instructables community. I was thinking of making a 12 volt battery charger with a trimmer engine (pictured) connected to a scraped car alternator (I found several on eBay). But I have a few questions: 1. Would such a combination work as shown in the illustration? 2. Would it be best if I directly connected the engine to the alternator with no drive belts or chains, or would the high gear of the large engine gear and small generator gear be worth the extra trouble. 3. What is the best way to connect the two? And 4. Where should I remove the engine from the "trimming part". Any answers will be appreciated. Sincerely Confused DIYer

I'm in the need of quite a few electronics for my new lightning tube project, on of them is a suitable HV transformer for high frequencies. Salvaging from plasma balls or similar is pointless as those transformers only get to around 3kV at best. With BW TV set getting really rare these days I decided to look into the modern version of the flyback transformer - the DST, Diode Split Transformer. If you ever did some Tesla stuff you will know that everyone says a modern flyback is no good as it only provides DC output. With basically no info on the net how these things look internally it was down to destorying a few until I got to know what to look out for andhow to remove the HV diodes between the secondary coil packs. I know not too many people will need a HV AC tranformer that can operate with several kHz so I though I ask first if it is worth to create an Instrucatable on this topic alone, otherwise I will just include a very short version of it with my Instrucable on the lighnig tube project. Have to say that is a quite messy and stinky procedure involving a lot of heat and the risk of burns to your fingers.

I am playing with an idea. Higher end cars come with active noise cancellation systems to make the drive quieter and more enjoyable. However compact and subcompact class cars do not. With the noise canceling technology is available on every shelf for headphones, I am wondering if this could be hacked and repurposed to reduce road noise in a car. The system (Im presuming) would require one microphone, one noise canceling circuit board, and one speaker per wheel well. So it would require two pair of noise canceling headphones to accomplish. The idea is to improve the cabin noise quality in an off the shelf kind of way. Currently there are no aftermarket systems within the normal financial reach of most people. Only a hand full of aftermarket systems out there are available and priced @ 4K USD or more. If this works, it could be marketed at around 100 USD per unit. And provide a much nicer driving experience to the compact and subcompact cars. By placing the microphones under the carpet and on the wheel wells metal surface the system should ignore the stereo, and correct road noise transmitted from the wheels to reduce cabin noise. Stereo interference is a common problem with cabin mounted microphones on OEM systems. So, your mission if you choose to accept it, is to devise a way to reduce road noise in a compact or subcompact car using off the shelf noise cancellation circuitry available to the average person. If your successful this should be a very easy way to upgrade most cars not equipped with such a system. Having a noise canceling system in a car reduces noise fatigue, and improves the driving experience for all of us.

I've stripped a 1.8 deg stepper motor out of an old fax to make a bike generator but I can't get any juice from it. I'm spinning it using a multi tool so I should get something, right?! I did do some research and found out that 4-wire bipolar stepper motors are controlled differently from 5+ wire ones. I guessing then that generating power is different also. I'm reading 2.1 - 2.3 ohms off each coil. Tried wiring the coils in series but still nothing. I need a long serving instructablator to help me!!

(crossposted in, ummm, not sure what other forum yet.. lol... in case no one reads it here) I've been thinking of several ways to build a device similar to a Ditch-Witch©™ for narrow/shallow trenches - like for coax cable and antenna radials etc. but keep coming up with examples that don't look they would really work - things like a modified chainsaw (running at low RPM) or a high-torque circular saw with a modified digging blade. The problem seems to be *how to dump the dirt next to the trench, not back into it* Sure, I could rent a *real* trencher for a couple hundred dollars for a quarter-day, but that's not really feasible as I'm on a fixed income. Any guidance from the collective genius of the group? Thanks bunches!!! Tom

I recently ordered a REX C100 for my electric melting furnace project. As it came already with a SSR and temp sensor I only added a sensor capable of reading more than 400° of the supplied one. These controller are dirt cheap and have lots of support in the modding community - although you now can get them new in all variations so no more modding required. Internally they run on 12V DC, so even mobile use is possible (but this time after modding). My problem with this controller started with the not included manual. As it is no China clone but an original from RKC Japan, I downloaded their manual and tried to adjust the max temp settings as well as changing to the thermocouple. To my surprise the menus for that simply did not exist on my model. Reading a few more manuals showed that to get to the "initial or factory setup" you need to change the lock code. Here things get confusing: Once in the lock menu setting most manuals state to enter "0000" to activate the hidden menus. (Mine was alreay on 0000) Others state to set the code to "0100". In any case you have to hold the setup key for a few seconds to store the changes and after that hold the settings and shift key for about 5 seconds to enter these factory menus. After being close to send the unit back I tried different code combinations and finally found that "1000" actually activates the hidden menu on my model! But again there was no joy as several vital settings still did not show up. To finally get all settings another step is required: The first item in the hidden menu is "CODE" and it shows as "0000". After changing this to "0001" the setup key can be used to get to the settings to change the max and min temps. Once all this done the controller actually shows the selected sensor and if Celsius or Fahrenheit is used at the start and from now on simply by clicking through the hidden menu with the setup key you can get to the min and max temp settings again. I hope this info will help someone running into the same brick walls as I did...

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...

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!

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 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 email@example.com
