Invisible Comments, now with video.

I've just noticed - if you enclose a comment in , they don't show up on your "comments" page.  You just get an empty space with the name of the person who posted it. I guess the system thinks that the contents of are supposed to be code of some sort, but it's an odd effect anyway. As an aside - what is the best you can do with the image below?

invisible comments

Several family members are now Instructable members so occasionally we like to check and see what each other has said about an Instructable. On every occasions when we go to the Instructable comment section we can not find each other's comments. To double check we swapped member names and passwords but as feared we could only see the comments for the member names we were logged under. Ironically we can see all (?) comments by other members. I logged this as a bug and sent several emails to but nothing, no response and no reply. Has anyone else experienced this trouble or have any idea of the cause?

Comment going down the memory hole....

As has been reported by other users, I occasionally end up posting "invisible" comments, either at the top level, or as replies to someone else.  These comments are visible to me when I view the forum topic, Question, or Instructable (and the comment count includes them in that view!).  However, the forum browsing page doesn't show them (neither as "last post" nor in the count), and they are not visible to any other users. My most recent example is in BIGHAIRYDUDE's bug report. I posted one comment at 4:18 pm (CAGESVXGGMMFD6M), and another at 5:08 pm (CTRYNTKGGMMFDBI). Those strings are the commentId values, which I can see on the page when I do "view source"! I constructed the URLs by hand. If I use those links in another session where I'm not logged in, they don't work. But if I log in there (on Safari, so there's no chance of cookie or cache confusion), then my comments appear! This behaviour is unpredictable. It seems to happen once or twice a week. When it does, the particular forum topic or whatever is affected permanently (i.e., any comment I try to post is invisible), but other topics are not affected at all. I know that's going to make it hard to isolate and fix, but I'm hoping that the IDs might be of some help...

I can't see my instructable

Last night I published this instructable, but I can not see it in ALL RECENT option. However, it has a comment. I don't understand... What worries me is that when you solve the problem, my instructable will appear "backward" or as posted several hours ago, and many people will not see it, for that reason.

Invisible concrete cube

This concrete cube made by Daniel Franke and Markus Kison has the amazing ability to turn invisible. Thanks to eye-tracking and a video projector for each face of the cube, the cube has the view behind it projected onto its faces. The result is like looking through a glowing window instead of a cube. You can see the effect in the video. It's not entirely smooth yet, but a very cool idea.

The Future of Invisibility

It is reported that a team of researches at the University of California, Berkeley claim to be on the doorstep of invisibility. Using a special type of metamaterial they are bending electromagnetic waves and negatively refracting visible light. Their ultimate goal is to render entire objects invisible to the naked eye. After reading this, I conducted some invisibility experiments of my own. Based on my initial experiments with invisibility cloaking, I must concede that we are not quite there yet, but are getting close (see image).For more information, read the full news report

How to make florescent ink?

I have Googled and searched Wiki on how to make fluorescent (ultraviolet) inks. I want to know how to make them. I dont want th lemon juice , corn starch, milk or other types of invisible inks. I want to make the stuff the glows under uv light. I searched using uv, ultraviolet, fluorescent inks but couldnt find anything other than the lemon juice and other types of "invisible" writing. Please help if you know where to find or if you know how to make fluorescent (ultraviolet) inks. You can email me at I mean the inks that u can buy for handstampers and that are put in invisible ink markers. I want to make the stuff myself and not have to buy it off the internet....

Further Advances in Invisibility

As those of you who have been fervently following my posts for over a year know, last summer I was working on making myself invisible. While my the results of my experiment were lackluster, it appear that a man in China has nearly perfected the technique. He says his quest towards invisibility started in 2005 as a protest of the Chinese government who had shut down his art studio. You can see some of the results of his research here.

Micro Invisible fence transmitter

I am looking to have a Micro transmitter for an invisible fence made. This will need to trigger the invisible fence shock collar when it gets within 2 feet. I have a dog with a shock collar that attacks a smaller, older dog in the house. I want a transmitter that will fit on the collar of the smaller dog, run off of batteries with a LED to show it is powered on. I have an extra receiver to test with, and i can send photos of the transmitter and what information i have. Willing to pay COD for delivery.

InVision LD 3D Printer Help

A 3D printer has been donated to my classroom for a few months, but we were not given any documentation on the printers use. I have looked online, but it is an older 3D printer and information is lacking. I thought I would see if anyone here had experience and could point me in the right direction. I have been to manufacturer's website but have had little luck since it is a legacy system. I have looked online but I cannot find a manual. If I could find a manual that would help greatly. It is an InVision LD 3D Printer, S/N 05JA1921 Thanks!

Chmistry buffs: IR invisible ink?

Hey all science-type people, I've seen invisible ink pens and things for sale that contain ink that show up in infrared, instead of ultraviolet light.  That's really appealing to me for a number of project ideas because digital cameras pick up IR exteremely well (especially with their filter removed). The problem is I think I'm going to want a lot of it, and those dumb little pens are crazily expensive. So any of you chemistry buffs out there have a secret formula I could make?  I'd prefer something invisible in regular light, but hey, whatever you've got. :) Thanks in advance for your help, -Kurt

Indoor invisible pet fence idea - need help

I need to keep a cat out of a room that has a 12 foot wide opening. I was wondering if a strand of wire or a coil of wire could be installed under the carpet across the 12 foot opening such that when the cat, wearing a collar fitted with a magnet came close, a current change would be created in the wire or coil and an alarm could be generated that would scare the cat away? Would this work and if so, would someone like to help me make it happen? Thanks

IR laser detector alarm

With the new Infrared laser pointers etc. there is no way to tell if light is on or not. I think there is a need for a IR laser light detector that is small enough to fit in your pocket and could be clipped to your shirt. If a IR laser was pointed in your direction the sensor would chirp or make a noise. I've noticed several places selling IR laser pointers. I think they are dangerous and very little use for them, since they are invisible. Anybody want to make one? If you do I want one.

Feature Request: Sort Group Topics RECENT by default

As announced this morning by Rachel (and confirmed by me), it is now possible to create discussion topics within a Group.However, when we view a Group, those topics are presented in the order in which they were created, from OLDEST to newest. That means, for many Groups, the new topics are completely invisible to anyone visiting. There is no way to change that sort order from the Web interface.I would like to request that the "sort=RECENT" CGI argument be used by default for the presentation of Group topics, both on the Group page and also with the view all link. I have confirmed that adding this argument by hand to the URL has the expected effect.

How fast can you spin your Golf Ball?

I played around with some balls placed into the airstream of a little blower. Everything light enough just "danced" in the air like being hold on invisible strings. But not so much the golf ball! You would expect those dimples are good for reducing air friction but do they also offer stability in some cases by making the ball spin? Check this video I recorded while playing - to me it looks like with a proper nozzle there is even more speed possible. How fast can you make it spin?

As soon as I click the box to enter my search terms, I'm directly transported to whatever suggestion is coming up, such as beer or the alphabet. This was something I could do at the latest last week. The positive part is that I found the small one in the upper right corner after several years as a member. Got kind off invisible with the main one being so big.

A sport coat that has hundreds of little lights sewn into it.

I once saw a local musician play the guitar and sing in a small venue. For one song, they dimmed the lights on the stage almost completely, and the sport coat he was wearing suddenly "switched on" and he had hundreds of tiny little light beads sewn into the jacket that you could not see before. They were not string lights, like for a Christmas tree. They seemed to be much more LED like, and bright, and most of all, small to the point of being invisible.  I hate to be a copy cat... but I want to make a jacket like this too. I do not care if it is portable. i.e. if I have to plug it in, that's fine. Anyone have any ideas for where I might start?

Sandals made from billboard fabric

The barefoot trend keeps catching on. About half of the Instructables staff wears Vibram Five Fingers shoes and Eric has even run a marathon in a pair. But it's totally understandable that people would want some even cheaper alternatives, such as the invisible shoe. Now there's an even cheaper option coming along that's made out of billboard fabric. They're called Paper Feet sandals and are set to go on sale this summer for $5-$15. Now I'm a little dubious about the comfort of such shoes with some potentially sharp edges, but it's cool to see people constantly trying out new ideas. Hopefully this one turns out well.

If you want more details, and are ready to try them out, PM me and I will pass details back to you.1. A ghost costume for a Lego man (low cost and difficulty, I just lack certain tools)2. An invisible hallowe'en costume (Cost $10-30, much less if you have access to theatrical make-up, I have already sourced all specialist parts - I just lack an appropriate place to wear it)3. A pumpkin substitute for decorations - low cost, more novelty value than anything.I reserve the right to refuse to send ideas to members who do not seem to be set on actually making the 'ibles.

Instructable not selected for contest

I recently published an instructable( and added it to the Kit contest and Arduino contest while publishing. The instructable was only visible on my 'you' page and was missing from the technology or recent sections. I checked earlier questions and learned about filters. So waited patiently. After 3-4 days(2 were weekend), it became visible. But it didn't get selected for any of the contest. The Kit contest is now past the period of taking submissions. I'm not sure if it's the mischief caused by the filters or it got rejected. The mail instructed that if I don't hear back in 1-2 business days, I should consider it rejected. Should I add to Arduino contest again or wait?

Laptop Password Help

OK, so I'm typing on this laptop...It was assigned to Kitewife by an ex employer who seems to have forgotten they assigned it to her several years ago.If they ever ask for it back, we will happily hand it back, but they treated Kitewife very badly for quite some time before she left, so we have forgotten that we have it.Anyhoo, it works OK, little slow, but fine for the boys to use. Except that it's software hasn't been updated for at least three years. There are whole chunks of the internet that are invisible to it. The Flash, Java, Adobe, even the anti-virus are stupidly out of date.Unfortunately, the laptop has an admin password.Now, I could ask Kitewife's ex employer what the password is, but they might remember that she has it.So...Any ideas?I've had a look at the various password "hack" ibles, but they haven't been any help.

microwave "anagram"

I have that maker-ish compulsion to disassemble any and every broken or otherwise defunct appliance, gadget or device. For example, my microwave just "went to sing with the choir invisible", so I have begun turning it into a pile of parts. I got to thinking- as many of you must have doe before- "what can I do with this stuff?". Just like anagramists take words and shuffle their parts (i.e., letters) around to make something(s) new, different and/or clever, I'd like to try to do the same thing with my old appliance. But more generally, I wish there were a database of appliance "anagrams"- a list of clever projects classified according to the appliance from which the parts come. Anyway- if anyone has an idea what could be done with an old microwave (I've got my eye on that big capacitor...), please hold forth!

Joining carpet pieces

I'm looking for ideas on how carpet pieces might be joined together into a whole (e.g. rugs made from carpet samples). The gaffer tape solution which is posted all over the web in tutorials isn't strong, only lasts a few months and doesn't work well with small carpet pieces.  I've successfully sewn carpet piece in the past with fishing line (so the stitches are strong and invisible) however this technique only works well with larger pieces due to the time it takes and amount of work.  Has anyone here tried any other techniques and been successful with both large and small carpet pieces?  My other idea was to use wood glue to glue the pieces to a hessian sheet.  I haven't tested this but the hessian base on most carpet pieces should merge well with the hessian sheet. thoughts or ideas appreciated.

Wanna know how to disappear and become invisible in an online game such as KILLZONE,SOCOM,....... Racing games.......(the list goes on and on.....) You will need: Ethernet Cable Small Switch Gaming system (online compatible( ps2,ps3,wii,xbox,xbox 360,) ( must be connected with a wire WIFI wont work Online Game All you have to do is cut the orange wire on the inside of the cable and put a switch there. then put the switch in the of position when you want to disappear. NOTICE: This may not work with all games. this only lasts about 7-10 seconds and then you are disconnected from the network. It is just like unplugging it but it is easier. ????: Why is there 8 wires in cat six (maybe its cat five) cable and olny four of them are used ? (waste of coper and bpa releasing plastic) Would have made an instructable but its not worth it. Yes cheating is weak I just like the disappearing part You don't disappear but nobody can see you

Constructing a realistic lasergame

I am making a laser game/tag system and I would like an IR detector/sensor that can tell the difference between a direct hit and a near hit fly by so that the "bullets"can still cause sounds on a near hit. The sensor should be as invisible as possible but should have a very clear and acurate detection. If there is no way I can make it work I will tweak the guns to be louder. Guns will have to hit over atleast 200 meters "For snipers". I know I need a double-convex lens but I just don't know wich LED I need. It would also help if next to a focused LED there is a way to send an infrared signal in all directions for just a while "For explosives". I have looked at ad hoc but no idea if it would work in there. For the suits I will most likely use sensors connected to a micro-controller/processor. Oh I forgot to mention that I am not using infrared lasers because they will most likely burn or damage the equipment.

How to use Fiber Optics?

I am making a super-discreet earpiece/IEM that is intended for any use where you feel bored, where you are not supposed to use electronic devices. Meetings, lectures, classrooms, etc. Basically, it's a 3.5mm jack wired to a Balanced Armature driver. Essentially, I remove the big, thick and bulky housings of earpieces and leaving the smaller drivers in place. I've been using thin copper cables in the earpieces I buy. They work, but are still visible. I found that optical cables are near invisible, glass-like. I intend to wire them into my earpieces. So, do I require lots of circuits? I can do those, if they don't poke a black hole in my wallet. No more than USD100, if entirely possible.  I just want to know how to change electricity into light and back again, and allow for audio transfer from MP3 player to earpiece drivers.

Best solar light, UV LED to use for UV Sun Jar

I'm making a Sun Jar, but I want to swap out the normal white LED for a UV LED. My plan is to spray the inside of the jar with invisible UV reactive paint, so when then LED comes out, the jar suddenly starts glowing a different color. I tried making one tonight, but wasn't happy with the results.  I was using the black plastic Hampton Bay light from Home Depot -;=100068888&langId;=-1&catalogId;=10053&ci;_sku=100068888&ci;_src=14110944&cm;_mmc=shopping-_-googlebase-_-D27X-_-100068888&locStoreNum;=1002&marketID;=48.  It's only powered by 1 AA battery, and the resulting glow from the LED was really dim.  I got no reaction at all from the UV reactive ground marking paint I was using in my test. Any suggestions?

Metro 2033 Light Sensor

I'm working on a Metro 2033 cosplay costume and being the gadget-geek I am I'd like to make a working copy of the light sensor Artyom carries on his wrist. For anyone who haven't played the game (or read the book, I bought it today but I don't know it he's got the same thing there) it's basically just three LED:s (red, yellow, green) that light up depending on how well illuminated you are (red=fully illuminated=people will see you instantly and shoot, yellow=partly illuminated=people will see you unless you take cover, green=as good as invisible unless you give away your position with noise or flashlight). In the game it's abut the size of a 9v battery but flatter and for simplicity I'd like to keep it like that; I don't fancy carrying around an Arduino or something like that on my wrist. Here's a picture:,Metro-2033.jpg So, my question is: Is it possible to make something like that small and simple enough to be stuck to a wristband?
