Nema 17 stepper motor problem, how can I solve it?

Hello guys, I finally get done my Laser Engraver with Arduino, it's actually a combination of 3 projects from here, and now, at the end, my motors does not work...Here you can find the motor I use: https://www.aliexpress.com/item/Free-shipping-1PCS...I connect them on a cnc shield with A4988 drivers, I use GRBL as a firmwale and the program for engraving I don't think they matter, because I use 3 of them with no results.P.S.: the Laser is working, the M03 and M05 functions works great, but the motors not a step...Thank you and I accept any speculations, I was thinking that the current from the driver was not enough, but after a research I found that isn't true ( I think ).

Tim's Cybot conversion to Arduino NANO

Hi all.I'm doing a new project.Dug out my Cybot. The one built on a fortnightly issue of Real Robots back in 2001.I decided to convert it to use the Arduino NANO. With Bluetooth and Infrared Control.I haven't finished it yet, so I haven't done an instruction here, I thought I would wait until I have finished the project before doing that.However, as it's quite a lengthy project, I have started a blog on my google+. Which I am updating as I progress with the project.Here is the link: Tim's Cybot conversion to Arduino NANO Blog.Before I started I had a search on the net to see if anyone else had done this, but all I found was basic stuff controlling the drive motors.Currently I have done a rough sketch (some fine tuning still needs to be done) for it that lets you:Control it via bluetooth,Set it in line follow mode,Set it in light follow mode,Set it in avoidance modeandControl it with an Infrared Remote.I'm sure there is still a lot of these Cybots out there, so i thought their may be some interest.

Is there a Arduino code that can read the subjects emotions?

Hello there! I was just wondering if there was a Arduino code that could possibly read the person, who is using it's, emotions? I am trying to build an animatronic suit that also doubles as a costume. I wanted to make the ears move due to emotion but I haven't been able to figure out any code that could accomplish this though............. Hopefully I can figure out something though!!!

Avoiding corrosion when bolting galvanized steel drawer slides to aluminum for camper van bed

Hey guys,Going to build this bed:or something very similar. She says she has 6 sliders at 100lbs each, but I imagine she has 6 slides at 100lbs per pair. Either way, I've already purchased 3 pairs of 500lb drawer slides. The problem is, they're galvanized steel. How do I attach them to aluminum L beams? I can use some thick mil rubber tape between the two materials, but what about the fasteners? Some sort of plastic washer and polyurethane sealant around the head and threads touching the galvanized rail side? What should I use to isolate one from the other?FWIW, I'll probably use 6061 for the frame, which I believe has an anodic index of .9-.95, and the zinc rails are, I believe, 1.25. They're within or close to the .25 threshold so am I worrying about nothing?Cheers

Iphone controlled Gopro?

Ok, total noob here. First, I have a knockoff Gopro camera (Pyle). Are there instructions out here to build the capability to basically turn the camera on and off at will, remotely via cell phone? I'd like to be able to see what the dog is doing during the day. Since I have a "gopro", I'd like to just plug it into a device that I can turn on and off via the internet. This allows me to use the camera for an additional purpose. I would envision a box with all of the electronics inside that has a single cable that plugs into my camera. The box would be hooked up via Wi-Fi in the house to the internet. Not sure if I'm describing this correctly or not, but thanks in advance for help / advice / etc.

Arduino with flow sensor and relay

Hello. I'm needing help on a project with a water flow sensor. Basically, I'm trying to activate a relay (to turn on a motor) when the Arduino board senses any water flow present for 15 seconds or more. I was expecting the relay to turn on after the flow sensor picked up water flow for 15 seconds. After I ran the code, I had water flowing through the flow sensor for 5 seconds and then I shut off the water. The relay still turned on 10 seconds later. I didn't want this to happen. Instead, I would like to have the relay turn on only after there is water flow for at least 15 seconds. Please review my code below. I would appreciate any help. Thank you!!!byte sensorInterrupt = 0; byte statusLed = 13;byte sensorPin = 2;const int threshold = 15000; // thresholdfloat calibrationFactor = 4.5;volatile byte pulseCount; float flowRate;unsigned int flowMilliLitres;unsigned long totalMilliLitres;unsigned long oldTime;unsigned int countstart = 0;unsigned long starttime;unsigned long endtime;unsigned long elapsedtime;void setup(){ Serial.begin(9600); pinMode(statusLed, OUTPUT); digitalWrite(statusLed, HIGH); // We have an active-low LED attached pinMode(sensorPin, INPUT); digitalWrite(sensorPin, HIGH); pinMode(7, OUTPUT);// connected to relay pulseCount = 0; flowRate = 0.0; flowMilliLitres = 0; totalMilliLitres = 0; oldTime = 0; attachInterrupt(sensorInterrupt, pulseCounter, FALLING);}void loop(){ while (1){ if((millis() - oldTime) > 1000) // Only process counters once per second { detachInterrupt(sensorInterrupt); flowRate = ((1000.0 / (millis() - oldTime)) * pulseCount) / calibrationFactor; oldTime = millis(); flowMilliLitres = (flowRate / 60) * 1000; totalMilliLitres += flowMilliLitres; unsigned int frac; Serial.print("Flow rate: "); Serial.print(int(flowRate)); // Print the integer part of the variable Serial.print("L/min"); Serial.print("\t"); // Print tab space Serial.print("Output Liquid Quantity: "); Serial.print(totalMilliLitres); Serial.println("mL"); Serial.print("\t"); // Print tab space Serial.print(totalMilliLitres/1000); Serial.print("L"); pulseCount = 0; attachInterrupt(sensorInterrupt, pulseCounter, FALLING); } if( totalMilliLitres > 0 && countstart == 0) { starttime = millis(); countstart = 1; } if ( totalMilliLitres > 0 ) { endtime = millis(); elapsedtime = endtime - starttime; } if (elapsedtime >= threshold){ digitalWrite(7,HIGH); // Activate relay to turn on motor delay(10000); digitalWrite(7,LOW); // Deactivate relay to turn on motor totalMilliLitres = 0; countstart = 0; elapsedtime = 0; break; } else{ digitalWrite(statusLed, LOW); // Turn the LED off digitalWrite(7, LOW);// turn relay OFF } }}void pulseCounter(){ // Increment the pulse counter pulseCount++;}

New website login issues

I have noticed that with the new website logging in is somewhat messed up. Example:Get an email from instructables, click on something interesting - I am not logged in. Click on the 'favorite' icon - sends me to the login page, where I log in, which then redirects me to the front page, not the page I was favoriting. Hit back twice to go back to the page I was viewing, expecting that the login infomration would be cached now, but when I hit the favorite link, I am again redirected to the login page, and then again back to the front page.Frustrated now, do a search from the home page and try to find the page i was looking at so that I can finally mark it as a favorite. ----Secondarily, as another data point, I don't think that the new website layout is an improvement. Too much whitespace in lots of places.

Instructables Editor

The instructables editor has two annoying bugs:(1) Text high-lighting does not show when writing an Instructable ... it only shows in the preview screen. It should be WYSIWYG.(2)If you decide to take a break, before publishing your instructable, and click the "You" button, your only option is to "Logout" ... all of the other options such as "Instructables" are masked by a floating window. It's a real pain to have to log back in ... is there a (hidden) screen option that I can't see?

How to replace BT Headphone Batteries?

Hi, I own an Alcatroz Airwave 300 for 6 months and I have issues with battery. I always use it when I got home from school, doing homeworks, doing household chores, even going out to the public. I always charged it until its full but they only last for 2 1/2 hours. Recently, I noticed that my battery discharges easily. It doesn't last for 5 mins. So I decided to open the headphone where the battery and bluetooth module was installed, then the battery inflated and exploded. I was lucky that i'm not hurt but then I had no money to replace those. The warranty on this thing voided so I got no choice but to replace it. One day, I was looking for a potential replace for my headphones then I found my old nokia. It's display was damaged but the battery is still good. After 6 years of owning it, I can't believe that my Nokia battery still runs good as new. I thought to myself "why not". Also there is another problem, I don't even know how to solder a simple wire. I have the basic equipment so I need your thoughts and advice including how to do it.Note: before the battery exploded. I lost my receipt after I puchased it, without it, then I have no free warranty. Plus these thing were the last of its batch ever sold as a bluetooth portable headphone.

Pictures cut off

I started writing a new Instructable and noticed that when I use the preview function the pictures are cut off and therefore weirdly off centre. For some of the pictures it doesn't really matter, but some like I said look weird (as shown in the pictures). I don't see why there is a need to cut the pictures. Is this just an error and will it look better once the instructables is published?

How to avoid CNC crashes

Hey.I am wondering if it is possible to define particular areas on the bed of my CNC machine which I do not want the toolhead to pass over. My setup is an Arduino powered CNC pen plotter running GRBL. I am generating GCode in inkscape. I know I can set a safe height for the tool to pass over work safely but what if that height doesn't suffice. Can I define an area that the tool must not pass through?As a simple example:Before running a file the tool is at the origin. On sending the file the tool will take the most direct path to the first line to cut/draw. Imagine there is an obstacle that would cause a collision if the tool takes this direct path. Can I do something to ensure the tool navigates around that obstacle?I hope that makes some sort of sense :)Any ideas appreciated

ESP8266 Huzzah automated connection protocol

Hello guys! I would like to make a very small android app (or anything easy to use) so that at first :1. The ESP functions as a Wifi router in a local area (so no internet access) and allows anyone using a phone for example to connect to its network to enter the credintials of his home wifi2. The ESP board automatically changes to Wifi client and connects to the given SSID/ PAssword entered by the user. This would allow people to change ssid connections on a different wifi access point even if they don't know how to use any IDE. If anyone knows a tutorial or another topic with the same question i'd be happy to know ! Thanks

Fix the stubborn airplane mode in Windows 10

Since I got a Microsoft Update on pc, I got my airplane mode stuck to ON. I tried every possible solution provided by the internet but it got me nowhere. I tried troubleshooting it through Windows default troubleshooter, I went on to edit the registry files through registry editor, tweaked network and sharing centre but everything brought me nothing but failure.I had to reset my PC which uninstalled all of my installed programs, games and applications that were too important for me just because I thought this would set everything straight and I'll have my wireless connection back but again I got nothing out of it. You won't believe what actually the solution was. It was just a combination of the Function key and the Print Screen key that solved my problem. Earlier than this I used to have a wireless receiver to use the wifi as the inbuilt wifi was not working but this key combination enabled it and now I don't need any external wifi receiver to access the internet.

Skewed Contest Judging? Better Feedback?

Hello all, In recent contests, I've noticed that the judges seem to favor entries that require more expensive equipment, parts, or tooling, e.g. laser engraved parts, CNCs, and 3D Printers to name a few. As an entrant and community member who has none of these tools nor the budget to get them, I feel this is a bit skewed and not true to the open source spirit fostered here on Instructables. While I do agree that all of the entries that use the above should have an equal chance and are just as good as low-tech entries, I believe that more emphasis ought to be placed on projects that anybody can create without such tools or skills. I admit, I am a bit biased in this area of discussion, however, my point stands. Please tell me if I am making a wrongful accusation here.I would also like to see a feedback system put in place where the contest judges give a few pointers so entrants that did not win can improve their future projects and understand why their entry did not achieve a winning status. I feel that this would give an even more positive, community-friendly atmosphere to the site overall, instead of discouraging people who put a lot of work and time into their project and yet didn't even finalize. Has such an idea been considered? If so, why was it not instituted?- Dangerously Explosive

Challenge - RFID reader + Wifi Module Low Cost.

Hi Guys,I'm an Oracle Architect and I have one customer that want to monitor water dispenser, he wants to know if water bottle was changed. I have a software to control it, but actually the people need to input this data manually and I would like one solution to do it automatically. I'm thinking to use RFID Reader on water dispenser and paste passive tag on water bottle and with this I'll receive the information and this data must to be send using wifi, I can't have cable in this solution (data and power cable is not possible). In my investigation, I just find rfid reader (UHF) able read a passive tag in 1 meters distance, the issue is, the UHF module is very expensive, I saw UHF module for 40 USD and I need something more cheaper. Is there another way to do it? I need suggestions and help to developer it.If need more info, send me email.Regards, Haysar Lelis

Problem - Reusing an image from the Library and editing it's tag edits all Instructables using that image

I don't know if this has always been this way, or it might be new, but I just noticed something that for me is a big issue.Sometimes I reuse images from my graphic library of images I've previously uploaded to Instructables for use in other tutorials. That sounded like a great feature. However, I just noticed that if I use the same image in two or more instructables (selected from the library), if I edit the text boxes in one, it modifies the text boxes in all of the images. What a disaster! Now I have no idea of what Instructables I've screwed up in the past thanks to this. Sometimes I might want an image for one reason, and later I might want to use it to call out a whole different issue.Please consider correcting this. I thought the point of the library was to avoid uploading duplicate content to Instructables servers. Now I'll have to upload the same image as many times as I need to reuse it, since by default I intend to use different call-out boxes (or however they are called on them).If I'm getting this wrong, and this bug is actually a feature, please let me know how I am interpreting this issue the wrong way
