Nasty looking mobile ads

A buddy of mine showed me this pop-up ad he got when he was looking over a guide I made recently.  He had the same issue the last time I made a guide.  These pop-ups are annoying enough that he never uses Instructables because of it.  To be honest, I don't blame him. I know you guys use AdSense for advertising and I don't really know the solution to this issue, but I wanted you all to be aware of it.  Less internet savvy people might be freaked out by ads like this.

Malware Mobile Ads

The mobile site for Instructables has been presenting rather unpleasant popup advertising. This twitter thread captures it rather well: https://twitter.com/winkleink/status/897077681443024899 Attempting to close these, or go back, results in more pop-up. The instructables content cannot actually be got to. It's not that users don't appreciate the need for ads. advertising maker sites - places for buying stuff, perfectly cool, and likely to get attention. Pop ups like this really make makers not want to avoid Instructables on phones. Seen on both Android and IOS.

Which one should i use for my Project? Arduino Pro Micro Or SparkFun SAMD21 Mini Breakout?

Hello everyone, As the title, I'm just wondering which one i should choose to do my project - Arduino Pro Micro Or SparkFun SAMD21 Mini Breakout. I'm a student, and i'm going to do my own smartwatch. It only has OLED display, the pulse sensor and SMS/Wifi module inside. I've read the documents about both, it both has a small-size and low-power as i expected, but i have no experience to make sure which one is suitable for my smartwatch. If there's someone who did do the similar project before, please give me some advices. You can suggest another micro if they're better than mine. Please help me.Thanks a lot.

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.

XYZ Recumbent Trike

So I've been wanting a recumbent bike to help me get in shape. I'm far enough out of shape that a standard bike is uncomfortable to the point of being a deterent. The biggest obstacle to me is the price. Even the Terra Trike which is supposed to be an affordable, entry level option is almost a grand even bare bones. I tried looking on craigslist but even used ones rarely dip below 800. So I looked for something I could diy. My biggest obstacle on that front is I don't own, or know how to use a welder. I think I've found something promising though.  There is a group in The Netherlands called N55. They are sort of a engineering/art collective and they focus on things to improve modern life. One of the projects they have out there is their XYZ Vehicles. They are pedal powered vehicles designed so that they can be put together with a minimum of tools. All that really should be needed is a power drill, some wrenches and a metal saw. From what I understand, they do classes where they build the 2 upright versions, the bakfiet and the tadpole design with the cargo box, but these are all over in europe and I am in Arizona so... I haven't been able to find anyone as of yet who has made one of the recumbents here in the states and posted about it. I would love to do this and post it as an instructable but I need some help. All of the materials list is metric and while I personally think a base-10 system makes a heck of a lot more sense that what we call standard measurements, I'm still not familiar with metric. So my question to the community is, should I convert all the measurements to standard or is there someplace i can buy these materials from here in the states in metric sizes?

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.

TR-8 Aftermarket kit, TR-36 "Overkill"

I know this works for cars, so I decided to put an extreme spin on KILLERK recent TR-8. The majority of the body is based of the TR-8, but as you can see I added a little different styling to the handle which is also used to support the heavy turret. I added a bit more of a stock to the original but kept the mechanics the way they were. (can't mess with perfection) The turret itself has a ratchet, similar to the TR-8 which allows the turret to only "wind up" in the correct direction. The turret is also attached the same way as the TR-8 with a socket joint in the grip of the gun. I threw some tactical rails on the sides of the gun to try to hint at capability with attachment but the turret is kind of blocking any attachment you would put there. Overall the TR-36 Overkill feel awesome (heavy) and with that phenomenal power and range you would expect from any turret gun. Tell me if you're interested in an ible' and I'll start working on making one.  Thanks for looking! JonnyBGood

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.

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.

Fixing broken power supply?

Have been using my FolgerTech Prusa i3 printer for a few weeks now, and was doing some cable management when, "Pop!" goes the power supply. I had the mains power unplugged from the power supply, and didn't connect or disconnect any other wires. I was working on hiding some endstop cables (That i will probably just go ahead and shorten later) and when i was satisfied with the job, i went ahead and plugged the printer back in. Pop! Immediately unplugged the printer to prevent further harm. Sounded as if a .22 went off in my room. No burning or acidic smell, just a pop. From the sound of it, i assumed it had to be the power supply. So i examined everything, the ramps boards, the arduino, etc. Nothing. Everything looks fine. I remove the power supply from the printer, and plug it back in. LED light stays off, no more sounds. Using my multimeter, i checked the output voltage, and sure enough, it's dead. So i go ahead and crack the power supply open, and begin examining the components. Nothing. Absolutely nothing. All the caps look fine, no charred marks, no scorches or burns. No component looks any different than its functional counterpart. Beyond the cheap chinese soldering job, the board looks fine. So i take the board off of the metal plate to examine the backside. Solder splatter everywhere, but no shorts or anything (It worked for about 3 weeks.). I do, however, notice that there is a nice dry joint on one of the large capacitors. Thinking that might be the problem, i go ahead and fix the joint by reflowing the solder. Put it back in its case, plug it in, nothing. Anyone have any idea what may have happened? I am a student who currently doesn't have 30$ to fork out for another power supply, but do have an arsenal of spare electronic components. (Will eventually buy another power supply, but currently don't have money to set aside for it.) What should i look for? What blew up? Why does it not work anymore? If any more info is needed, let me know!

How can I get rid of the smell of damp concrete in my studio?

I have been working without success on the smell in my 12' x 14' studio for 5 months, so I really hope someone can help me. I can put my nose right up to the walls and the ceiling and the outlets and not smell anything. But when I put my nose right to the floor I smell the dank, musty, yucky smell of damp, dank concrete. The place reeks of it, I can't work in it. I smelled it last October when I was looking to buy the house, I told the inspector about it but he could not smell anything. Everyone can smell something when they open the door, some people can tolerate it but I can't. As soon as you open the door it just overwhelms you. What I have done so far: 1. Had two peg board walls removed and replaced with chipboard, because that was what the other walls were made of. I had assumed at that time that the smell was mold coming from the pegboard. At that time I looked at the insulation inside the studs and it was fine. It smelled so good with that new chip board up that I thought the problem had been solved. 2. In preparation for painting I caulked the ceiling, around the windows, and up against the floors where it meets the walls. 3. Painted 3 coats of Kills primer on all the walls. 4. Painted 2 coats of very good quality semi-gloss paint on all the walls. 5. I scraped off all of the existing paint that was on the floor. It was peeling in places which is what led me to think the smell was coming from the concrete. 6. Washed the floor with a de-greaser. 7. Washed the floor with sulphuric acid, and rinsed it about 30 times. 8. Painted the floor with 3 coats of special paint made for concrete basements to act as a waterproofer. 9. Painted 2 coats of sealer on top. 10. I called the previous owner who confirmed that the studio's monolithic slab was poured without a vapor barrier because code didn't call for it, because no one was going to spend the night there or live in it. He never noticed the smell. 11. In all this time I have run the A/C non-stop, with the windows open, with the windows closed, with no effect. I have even run the heater for a few days. I have cleaned the A/C over and over, there is nothing to clean and the smell is not coming from there. Is there anything I can put on the floor to effectively seal the smell from getting into the air? Why didn't all those coats of concrete paint and sealer do it?

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

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

Measuring oscillation of a multi tool

I have a harbor freight oscillating multitool that is advertised as oscillating between 10k and 20k oscillations per minute. In reality to speed control goes from 0 opm to an unknown value. I’m trying to set the tool to oscillate at 35 Hz. What is the best way to measure the frequency of the tool and set it to 35 Hz?

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

what to do with a 50,000 volt Tesla coil?!

I just got a 50,000 volt Tesla coil (Oudin coil) for Christmas. I dont have a clue what i could use it for, i need inspiration. My uncle likes to surprise me with semi random things so other than shocking metal tables i just dont know what to do with it. ---from teachersource.com (where he ordered it)While more accurately called an Oudin Coil, these are commonly referred to as a hand-held "Tesla Coil." This coil is self-contained in a heavy duty Bakelite case which forms a convenient handle. The spark is adjustable from 10,000 to 50,000 volts at frequencies of approximately 1/2 megahertz. The high frequency spark produced is about 1" long and can be used for a wide array of applications. An instrument like this is intended for intermittent use only and must be turned off after 10 minutes of use. The electrode furnished is approximately 2" long and the instrument is furnished with an intensity adjusting knob. For 115v, 50/60 Hz. An improved SAFETY FEATURE is the ON/OFF momentary switch which is in the handle. This makes our Oudin Coil extra safe for classroom use. (Runs on standard North American line current, 110 volts 60 Hz)
