Has this happened to anybody else

Hey. I published my instructable, and entered it in the pocket sized contest over a week ago. There's no reason it wouldn't be accepted, and I even got an e-mail telling me my entry was accepted. So why is my instructable nowhere? I looked through every single page of recent, rating, views etc and it isn't anywhere. Hell, even when I type the exact words into the search (of the title) it doesn't appear. Has anyone else had this problem?

What is this electronic component?

During one of my part harvests I came across a rather odd component. It looked like a black rectangle with steel pegs protruding from one of its sides. The part's etchings are a white dotted line followed by what appears to be a mitsubishi symbol followed by the text "E 27k", an ohm symbol, then " 9428". I found this part on the board of what I believe to have been part of a tape recording machine. Attached is a picture of the component. If anyone can identify the part I would be eternally grateful.

Instructable is still hung up.

Need a hand with an instructable again. It seems mine keep getting "hung up" in the filters. When this happens, they stay in limbo for a good long time, then when they're finally pushed through, they're already buried on page 32 of the "recent" list. I've tried E-Mailing Ed and randofo 2 days ago, but haven't gotten a response. Anyone have any ideas how to deal with this? Or what "filters" are in place so I can avoid having my instructable get throttled, then buried?

Need Advice about how to: Stack 2 IVARS on top of each to reach the ceiling

I like the width and depth of the smaller IKEA Ivar bookshelf.  How do I connect stack 2 on top of each other to reach the ceiling. ? I need help with the design, then I'll ask my husband to help me. I've given up Billy's because they are so unwieldy. If you can think of another system which is shallow and narrow, I'm open to other alternatives.

Kelly's controller slowing down manually

Greetings, I'm looking for a while now but no solution, so wanted to post this question in here. Got a e-bike that can do 90km/u but I need to keep it 45km/u for road legality. But on private property on my job and stuff, don't need the 45km/u so I wish without to connect the controller to my laptop and stuff to make it go faster and slower, twice a day, it would be handy I could let it go with a simple push of a button go slow/fast. It's about this controller: http://kellycontroller.com/keb72601x24v-72v280a6kw-bike-brushless-controller-regen-p-279.html There is software for to download: http://kellycontroller.com/mot/downloads/Kelly%20KBL%20and%20KEB%20User%20Program%20Release%20Setup%20v3.3.zip Manual aswell: http://kellycontroller.com/KEBhelp.php Also, there is a configurable boost switch if I wanted, so maybe through that ... Or an economy function... If only that could be programmed, so I can set my engine power to 100% and the economy to what ever makes it run legal speed. Hope I gave some info, to make things up for what I ment ...

Request for Feature: Optional and nested quoting (a la e-mail, Usenet)

This probably would require substantial rewriting of the comment-handling software, but I might as well toss it out for discussion. Could the "Reply" feature for PM, topics, and I'bles comments have the ability to optionally do formatted quoting? I have in mind the classic Usenet and e-mail system: Joe L. User wrote: > Jane Newbie wrote: >> GodOfVMS wrote: >>> Why do we need lowercase commands? >> i like lowercase; it reminds me of e.e. cummings. What's a command? > CAN SOMEBODY HELP ME GET MY CAPS LOCK KEY UNSTUCK?????? Sure! On the front of your computer, find the button with a circle and line, (|). Press it.With long postings, or when you're replying to multiple comments someone has made, being able to interlace what they said with what you're writing can be very convenient.Some people (Kiteman especially) do this by hand, applying boldface or italic markup to distinguish the layers of markup. I try to do it in a more narrative way, e.g., On Sep 16, 2008, you wrote, "Some stupid newbie announcement." Did you really mean to say that, or were you doing a self-colonoscopy?I wonder if formatted quoting could be done automatically by the backend?

Thank you for the gift horse! Hey, what's that in its mouth?

A few months ago I entered an instructable that placed in both the Robot Challenge and the Make it Real challenge and have been having some, well, odd experiences with the prizes.  I've received all of the Robot challenge prizes, plus some. I was sent an extra pocket oscilloscope and arduino uno! O.o That's about $200 in extra loot and I would think you would like me to return it. I sent an email about this to service@instructables.com last week, but have yet to get a response. As for the Make it Real prize, I went back and forth with info@instructables.com for about a month and eventually was linked some kind of e-document for me to e-sign. That was about two weeks ago and I haven't heard anything since. I know you all have had some kind of re-organizing in the prize department, is the dust still settling? I certainly don't mind the wait, but when I got the double prize pack I felt that I should come here and let you know, as this is the only contact option I haven't tried. BTW: thanks again for the prizes, it has been a huge boon for me. I hope we can get all this recombobulated.

I know you are very sweet and compassionate and I hope you can forgive me for my silly mails.

L.E.D. Wall clock idea

I saw this clock design the other day. It was a circle with the clock hands in the middle and unattacked to the clock there were dots around it to mark the hours. I want to improve this design by making the hour dots light up on their respective time for the whole hour. Maybe make them have a nice dimming transicion between the hour switch at the last second. I don't know much about programming L.E.D.s or what hardware I would need. Can somebody help me how to make this project?

Featured but not Featured?

   I received an e-mail that said my 'ible had been featured, I checked the Featured page, but it never showed up. It has the feature banner on it, but only on the Recent page (2nd page). Neither does it show up under my "You" page. The link it gave me in the email has the feature banner, but it's only under the Photography section. This happened during my switch to Pro, perhaps that has something to do with it? I was working on the project before becoming Pro, then published it after I became Pro. I'm running FireFox 3.6.3 on Windows 7.

home made MOT pork chop!

I have a crazy idea to make a transformer for a tesla coil useing two MOTs that are exactly the same, Then cutting them so you only have the 2 "E" core sections, Pull off the primary off one, flip the secondry so its out of phase, put the two cores together and clamp them so they cant move. put some extra shunts in to help limit current, hook up the primary to a variac and turn up the power slowly and test the arc. PORK CHOP! pole pig?

Every single Instructable is verified by an editor to be on Homepage/Featured?

I'm just wondering if every single Instructable is viewed by one of the editors, or an algorith/program chooses the Featured Intsructables or both? I think that real people are choosing them, but someone made me unsure about that. So when an Instructable gets featured we get an e-mail that "one of our editors thought that you are awesome", so I think that editors are choosing them, but do they check all recent Instructables? Or have they any software help?

Knol.Google

Http://knol.google.com/I notice there's also "How to Backpack: starting from scratch", maybe they're trying to compete with E-How/Wiki-How too? Slashdot-Google has taken the wraps off Knol, its expert-written challenger to Wikipedia. Wired has an in-depth look. Knol's distinctions from Wikipedia are that authors are identified by their real names (and verified), and that they can share in ad revenue if they choose to. The service initially features a lot of medical articles, which is interesting considering that Medipedia also launched today. This medical wiki is backed by Harvard's and Stanford's medical schools.

Crichtonsaurus

 Micheal Crichton had a dinosaur named after him!! A new species of Ankylosaur was discovered, and named after the author of Jurassic Park. Granted, this news is 8 years old, but it is still pretty remarkable. The official name is Crichtonsaurus bohlini, is roughly 3 meters long, and named after the man that simultaneously had a number one movie, book, and t.v. show. (Image from Here). If you haven't read his books, he is a fantastic author, and I highly recommend them. Micheal Crichton R.I.P. Further Reading: @ Micheal Crichton's Website @ Wikipedia @ An E-Mail

The arm will have the same freedom of movement as a human arm. Eventually I want to use this arm on a machine such as a bobcat or similar device. For now I just need to be able to power this arm and then I can go from there. Anyone up for a challenge????

Does anybody know if it would be easy to make something like these shoes for under $75?The link below is the official site for these shoes.

Conductive Paint in RadioShack!

Hi everyone, just a quick note to say that our conductive paint pens are now available in RadioShack stores across the US! (and online too) If you're not already familiar with what we do you can think of the material as a paintable wire (but there is a lot more to it than that). Check out our new group page for some of our Instructables or you can take a look at our site for more info about the material and applications. Can't wait to see what everyone gets up to with it!

I posted it as I tough it was a nice one to share, but I'm having some comment on how it should not be safe using stainless steel in this project. As I don't have absolute knowledge about this before, and I just report what I learned, I was wondering if that was correct or not. (I know sometimes people comment very random stuff).

DIY Instructables Handbook

I just had a great idea, different instructables people should make different handbooks for different subjects that they are good in. Those types of books at stores are usually really overpice and have a ton of information that you'll never use and just makes the book fatter. I'm personally making an electronic on, fitting 4 pages on one 8 1/2 x 11 sheet, making each sheet of the book ~3.25" X ~4.5. If you make one please upload a pdf file so that others can download it, cut it, and assemble it to have a crafty pocket refrence!This is the table of contents of electronic book (so far):TABLE OF CONTENTSFormulas....................................Definitions andSchematic Symbols....................Conversions................................Prefixes.......................................Resistor Code.............................Capacitor Code...........................Inductor Code..............................AWG Specifications.....................General Electronic Tips...............First page:General outline:E=VoltsI=CurrentR=ResistanceP=Watts (Power)L=InductanceC=CapatanceG=ConductanceOhms Law: E=IRPower Formula: P=IEResistors in series: Rtotal=R1+R2+R3...Resistors in Parallel:Rtotal=(R1-1+R2-1+R3-1+.....)-1orstill working on it (and the subscribts and superscripts didn't translate too well, but you get the idea.If you have any formulas that you want me to put in the electronics reference then post a comment!Some topics for references could be:WoodworkingConstructionCookingRadioetc.

Marketing Instructables

This site is the business activity of Instructables Inc, and as such has to turn a profit (or break-even at the least). I don't know how the books balance or who has how much equity in Instructables Inc, but we do know that paid memberships (Pro accounts) have been introduced as an additional income-stream. Current Pro users number just over 600, so small money so far.A lot of complaints have been made about Pro membership, mainly in relation to what will be denied to free members, but also with regard to perceptions of an "us and them" division.If the site can successfully sell memberships and attract advertising revenue / sponsorship, it would not be necessary to annoy / nag free members by denying them basic features they won't or can't pay for.This is it: How can the site better market what it has to attract paying users willingly, and maximise other sources of income?E.g. gmjhowe's suggestion of Testimonials ("awesome" E Wilhelm)E.g. changing the Pro badgeE.g. changing the "recent Pro users" on the front page ("interesting idea" E Wilhelm) taken up unless it's just coincidence that it appears to be that wayThis topic is for constructive ideas around the introduction of new features and increasing site revenue, not for complaints (there are plenty of other topics for complaints)Personally I think the marketing of Pro accounts could be improved in some areas?L

It had to happen: Real SnailMail

In hindsight, it's inevitable that somebody would create genuine snail mail, and recruit actual snails to carry actual messages.The gastropods have been fitted with equipment to allow them to send e-mails on behalf of visitors to a website.Instead of instantaneous communication, sent messages will travel at 0.03mph (0.05km/h) and could take days, weeks or even months to arrive.It is part of a "slow art" project called Real Snail Mail at Bournemouth University in the UK which will be showcased in Los Angeles in August.Each snail is fitted with a tiny capsule which holds a Radio Frequency Identification (RFID) chip. RFID allows objects to communicate over short distances.Users of the service send a message via the Real Snail Mail website which is routed to the tank at the speed of light to await collection by a snail "agent".As the three snails slowly amble around the tank, they occasionally come into range of an electronic reader, which attaches the e-mail message to the RFID chip.The electronic messages are then physically carried around the tank by the snails until one of the gastropods passes close to a second reader.It is then forwarded over the net in the usual way. So far, the three snails have managed to deliver 14 messages.Users of the service will hope that Austin is on hand to collect their messages. The Snail has made 10 of the deliveries so far with an average delivery time of 1.96 days. SnailMail siteBBC story

Anyone wired up a ready-made multiple-LED globe?

I got a pair of these E10 6xLED globes. I basically wanna use these ones to replace some altar lamps I have which use normal E12 bulbs and keep blowing within a month or so of usage. They are lit pretty much 24/7. Has anyone had any experience in wiring up ready-made globes like these successfully. Are there any resistors inside these globes? Here's a link of the spec sheet availablehttp://www.jaycar.com.au/products_uploaded/ZD0300_data_sheet.pdfAny help would be greatly appreciated.Cheers,Teo

What happened to early entries in this contest?

I am just wondering what happened to the early entries in this contest? There are quite a few of them missing. I sent an e-mail to info@instructables.com about a week ago and received no reply. I had an entry, "Embed an OEM GPS Into Anything" and received no communication that is was disqualified, removed...etc. Just one day it was not in the contest anymore. Can anyone tell me what happened? Have any of the other authors already posted questions about this and I am missing them? Thank you all for sharing your knowledge and making this a great site! - Charles
