Double comments? I have been noticing this a few times within the last few weeks. Such as today. I got a comment from DJ Radio someone and then about 40 minutes later, I got the exact same comment. I'm pretty sure people are not doing this as a joke. When I'm talking about this, I'm talking about the comment tracker, it doesnt appear twice on the actual ible it is on. Has anyone else seen this happening?

Well hello! Just noticed a slight bug that y'all at HQ should know about. When I get a private message from HQ, such as the Halloween Postcard message, and the "Being Featured" message, I receive them twice.  Usually the doubles are quite some distance apart.  I received one double a day after the first one, and the Halloween Postcard message sent its double ten days apart (fearing that I needed to sign up again, I did just in case). Thanks a bunch!

I think somthing wen't wrong today. I opened my instructables as everyday and, Whoa, a double featured 'ible, that was unexpected. Is it a bug or a so good 'ible that needs double posting?

Here is my new pistol but its kinda different from others. its a 2 in 1 pistol. what do you all think should i post or destroy and use the pieces on something else?

Something a little wierd happened when I took a peep at the contest, some entries had decided to replicate themselves.... I don't know if this is simply an aesthetic problem or a serious issue but it seemed best to be on the safe side... It could also have something to do with some of the new stuff... The disconcerting thing is that the iron man one's aren't beside eachother...

Wow, not only have I just been made a "Featured Author", but I have just gained my 600th Follower! Thanks to Wilgubeast for the article, and a special patch to Supersoftdrink for helping me hit the big six-oh-oh. I've got to say I'm really proud to join the likes of Lemonie, Scooch, Jessy, Caitlinsdad, NoahW et al.

Hi !I tried to reproduce the Double-Slit experiment with a cheap red laser-diode (<1mW).Below are various results obtained from some variations of the experiment ... (with a double slit, with a pinhole, with a thin wire, and with a hair (and also with a single slit who gave almost the same result than with a hair))I also tried to reproduce it with an other source of light (and got electrocuted). But so far, I'm not satisfied by the results I obtained with the light bulb, and I failed with the sun.Do you have some experience to share about this experiment ?Do you have successfully reproduced it with an other source of light than a cheap laser diode ?

I guess the picture shows the bug quiet good, cleared cache and user data, should not be client side. Anyway my favourite category doubled \o/

Anyone ever cooked corn dogs redip in batter cook again? Best batter for corndogs?

Getting two email alerts for each comment. Something wrong, or just a temporary glitch during an upgrade?

I was charged twice on the same day when I signed up for my membership!  How can I get this corrected?

Recently i've been having to double click on the post button to get any posts on the Q&A or Forums to post. It's like the site isn't receiving the first click. It's happening across multiple PCs in different locations (ie miles apart). I've cleared internet and java cache with no change. Before this was happening i'd post a comment and the comment would be posted and the text field would still show what i had typed.

I made a doulbe barreled turret i dont have a pic because SD card readers broke sorry :3 it shoots 2 rods(most sizes) an then after it shoots those 2 u push the rotator pin forward and turn the drum and push the pin back

Here are some plans for modifying your stairs so that each step can also hold a drawer for extra storage of all your stuff. The things you put inside would have to be of the occasional-to-rare use since these look like a pain to have to deal with on a regular basis. Other concerns are just how well the heat will be kept above or below and if they can be spring loaded so you don't step into an open drawer on the way down the stairs and brain yourself on the landing. Oh yeah, the risers that get removed are often providing structural support for the step above so be aware of that as well.But if you can pull it off safely, it's a neat trick. link

Are oreo's double stuffed oreos really double stuffed?

I paid for my pro membership on June 1 with my American express card but then I saw on June 17 that Paypal also paid.  Please refund one of these payments.  Thank you.  

https://www.instructables.com/id/Lego-flower-vase/ I can't see the error in my edit-view so I can't correct it. It's not that important, but if someone is able to help, that would be nice.

There are three sets of LED I want to control, one function is dimmer, another is simple flashing LEDs, then I want two double blink LEDs( like a firetruck, blink blink pause blink blink pause) the simpler the better..i can find the first two circuits pretty easily , the third double flash is harder to find. is there a simple circuit that would do all three?

I have seen in some contests that double entries have been made, how does this occur? I mean while all the entries are being checked before accepting for the contests ,then still how does this multiple entries occur?

Where do I get the material to make a chaotic double pendulum. In fact I have a very tight time schedule - need this for delivering a lecture - so was wondering if someone has a double pendulum that they can provide (I tried chaoticpendulum.com but its all sold out). Thanks.?

Can anyone tell me how to wire this so I don't have to have middle switch on (exhaust fan) just to use the vacuum cleaner in either of the power points. Much appreciated.

I figure that this is a simple question, but I have a pretty limited knowledge of electronics. Would it be possible to hook two switches up (in parallel) to an LED, so that if either switch was toggled, the light would go on? I'm almost definitely sure it would, but just wanted to make sure. Thanks!

I LOVE this bracelet but can't afford to purchase it.  Does anyone know how I would make it?  Thanks for your help!  Best, Susie

I'm looking for a way to make my car boot open remotely, when my remote only has a lock and open button. I was thinking of making the servo activate when the unlock button is pressed twice in succession Each press sends a 10V-14V current to the solenoids in the car doors, so I've tapped into that I tried using a rc circuit, but it's way too unreliable, even when I have a voltage regulator at the input Does anyone have any other ideas? Something using the 555 ic maybe?  [EDIT] I have an idea; detecting if a door is unlocked or not, and it if is, then hitting the unlock button would open the boot *BUT* I need to find a way of making a delay; so when a signal is sent, there is a brief delay before it reaches a relay

Is anyone else seeing two of the same ibles?

I just double posted on this guide And when I tried to delete one of the comments, I got a little pop up that asked if i was sure I wanted to delete. I clicked OK and then the screen went blank and this was in the address bar: https://www.instructables.com/edit/deleteComment When I found the Guide again my double comment was still there. I tried this again with the same result.

Does anyone know how to make the double row macrame bracelet.  The bracelet looks like it is two rows of strung beads wrapped together and then finished off with a slide knot clasps.  I know how to make the basic shamballa bracelet and would love to make this one as well. Thanks,

I just posted some pictures and a short description of a new project on Flickr, and I was wondering if it is considered acceptable to post it here with the same pictures and description. I'm aware of Kiteman's law, but does it apply to double-posting on two different sites? Thanks, Noahh Update: I decided to post. Here it is.

Recently I have massive problems answering questions in the forum. If I press "post" nothing at all happens. After a bit of waiting with still nothing I press "post" again to see a double posting as the result. If there is no double posting I will get "error: backend read error" after about 60 seconds. Operating system is Win7 64, Firefox 31 in use with AdBlock. Checked with Chrome and get the same problem. Edit: tried now for over 30 minutes to post this as the preview only gave me a white page before.

I am looking for some 8mm threaded rod , but it needs to have a left handed thread on one side and a right handed thread at the other does this exist, if so, where can i buy it? thanks chris

Seeing two white Prius both with carpool stickers isn't that noteable. Seeing two white Prius both with carpool stickers, and with matching dents in their rear passenger side doors is notable. (The dent on the car in the back is difficult to see in the cell-phone camera image, so you'll have to trust me.)

Hi, I am in the middle of trying to figure out how to get my Arduino to power a 12V LED on a double flash for use in a model (USS Enterprise NCC 1701). The trouble I have is the double flash only has a delay of 0.7 secs so I think if I used a relay it would not be quick enough to turn on/off? The LED powers OK and runs from the Arduino on it's normal 5V, however it is not bright enough (I am going to hook them upto fibre optic so need the extra brightness). Any ideas how I can do this, presumably putting 12V into the USB connector would fry my Arduino? I have never programmed or used an Arduino before, nor have I done much in the way of electronics for 25yrs, so I am a little rusty, any help would be appreciated. To give you an idea of the speed I require, this is some of the program (within a loop). digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)     delay(70);              // wait for 0.07 second digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW     delay(70);              // wait for 0.07 second digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)     delay(70);              // wait for 0.07 second  digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW     delay(3000)         // loop after

Here we have a slightly angled pin knex gun. The pin is slightly angled down, making the pin come in the magazine well angled, hitting two bullets instead of one. It uses an internal flexy bullet pusher instead of the external ones. It shoots two bullets 30 feet using two bands. It has a yellow rod magazine that isn't removable. It also uses a unique trigger system. Its comfortable, light weight and is very fun to use. No sights, its just a prototype.

I wanted to know if there are any flight controllers that have separate sensors. I want to use 2 either quad, hex or octo flight controllers with one setup as + and one setup as X to make an octocopter, duodecacopter or hexadecacopter ( 8, 12 and 16 blades respectively ). I want to have a a 6 or 9 DOF IMU connected to 2 separate controllers for larger multicopters. Either that or would anyone know how one might go about designing an arduino controller using either a pwm shield or a TLC5940. Thanks in advance

Please gove me some advice on if i should post my gun or not.

When viewing the entries in the Toy Contest there are a lot of entries that show up twice in a row. The second page also has one or two like this. 

UPDATE:  Comments prior to 12 October also show the "double conversion" effect. In my forum topic from last week, https://www.instructables.com/community/How-small-could-you-make-a-working-computer/ , scroll down to find comments from 12 and 13 October 2009.  You will see that in cases where there were multiple paragraphs, or links included, the comment text is now being displayed as literal HTML source (e.g. '

ok i have the following parts to ue for this: (all leftovers from former project..)  :) 1x mosfet IRF510 power transistor 5,6A 100V 9x 2N3904 amplifier transistors 40V 0,2 A .0.625 W ~16x 1uF capacitors 50V ~99x recifier diodes 1A 50V ~35x 2k resistors  0.25 W the idea is to charge a battery pack consisting of 4x 1,2-1,25V = 4,8-5V 3000mah AA nimh batteries using my 5v usb wall charger that has 1A output! i tried connecting the battery pack directly to + and - and 'i think' its starting to charge but after 1-2 hours at full rate (5v 1a) it should be at least 50% charged (3 hours would be full charge -> 5W x 3 = 15W), but if i connect them they last for about 2 -3 minutes and then empty again!! so after this im concerned that i might need at lest 6V-10V to achieve the desired effect !!  -> charge 15W NIMH batterpack with wall charger (nokia ac-60e.. 1-1,5A) i nless than 3 hours (as like a phone would need !!) therefore i need a cuirciut (ONLY DC) to double my 5V OUTPUT to 10V (yiou shouldnt apply more than twice the curent of a batter pack) or ideally 6-7 V but i dont know if thats possible without a swiching IC or more different resistors.. so just doubling would be nice at the moment!!  

My double barreled shotgun, what do you think?ps I could have put more connectors in, I'm just lazy like that.

I am designing a double barrel shotgun style spud gun, i dont know if its going to work, if i am able to build i will work on a mod to make it break away style. any insight or tips you might want to give me please comment

Okay does anyone know how to do the double slap technique? Please let me know in written form (Because as i still have dial-up and can't get any better internet). also if anyone knows anyother cool techniques it would be cool if you shared those too.

I want to connect over to this socket however I cannot find available connector as I don't know the name of it. Searching on google for "double row 7 pin connector" doesn't yield results!

Hey, would anyone like me to do a video review on my double eagle ak47 airsoft gun? If i do it will be a video posted in a form topic because I'm not what you would call respected on youtube

We have our car shed roof made from double walled polycarbonate sheets, the problem is that the fabricator at the time of fixing it to the frame forgot to put tape on the holes to avoid dirt getting in. and that time I didn't knew about it, but recently I read this and the dirt has seeped in the holes which are about 7mm square in area. I googled it with various queries but to no avail, Now please help me by giving me some direction and steps to clean it. The dirt is fine sand and some mud which seeped in with rain.  I do not want to cut replace or open the sheets just clean them. it has seeped in upto 1.5 feet (roughly half a meter). See the following images, the dirt is just dark areas the rest is just on surface.

What i want to do have it so that i can have one hard drive that can be used on two computers at once. problem is the hard drive is used for the OS on the Desktop. so i want to some how split the connector to the Hard drive. one connector needs to be a SATA and the other a USB so i can connect it to another computer most likley my laptop. i'm will to make the cord but im not 100% how to or if its possible?

I recently picked up crocheting, and ran into the issue that I do not know where a HDC or DC stitch starts or ends. I have a pattern I'm working on that has a piece that is mostly HDC from the top to the bottom. Once the part is done, you have to do a single stitch around the entire part. Issue is: I don't know where to pick up to get a stitch on a half double crochet. I know it's a touch confusing, but I don't know how else to explain it. Hopefully it makes enough sense. Thanks in advance!
