Does a REAL online help system exist on this website? I mean as on any real application program you may be familiar with. Does it exist and if not why not? This site is mature enough that it should have a resource which anybody can go to to answer the question " How should work?" or "Does exist?" Up until now the only semblance to "HELP" I have seen is a forum where we all talk amongst ourselves and maybe somebody may throw in a nugget of real fact or wisdom. But nothing where I can go to get any authoritative information. Why should I have to wait (days/weeks) for a reply from the general hoipaloi instead of getting a (relatively) immediate answer to a simple question? In fact I have been a member for 14 months now and just today is the first mention of the word "staff" have I found. Staff?? No one in the forum is identified as "staff"! It seems as though no one is running the place. WTF? Why no real HELP!

Never mind---just read this if you're bored or something......Canida explained it for me What happened Instructables?! All of a sudden half of the instuctables on this site are boosted up a whole number! My best instructable used to be 4.08 which was very good but now all of a sudden its 5 exactly. I feel the new rating system is too easy and it is making it so every instructable has ratings which are way too high. I cant even sort by rating anymore because there's at least 1,000 instructables that are 5 stars and it doesnt show me the true best instructable of that category! Please fix!

I've been looking into setting up some greywater systems in my house to save money and water, my problem is that I also plan to make my own laundry soap using a combination of Fels Naptha soap, washing soda, and borax. what would I need to do to this water to be able to use it on plants? My yard is slowly becoming entirely garden that is usable for food, herbs, or other usable plants and I don't want to poison my foods or animal foods. Anyone that can help direct me to information on this would be greatly appreciated.

Hello guys, I need some help building a circuit. I'm new to electronics, so go easy with me. Is there a way to build and laser alarm circuit but instead of the alarm going on just when the beam is broken the alarm stays on until I turn it off? Circuits like Kipkay's only go off when the beam is broken. How can I make the alarm stay on once the beam is broken? Thanks

Hi everybody, Not long ago I had an idea about a messaging system based on a simple client-server architecture. Nothing new so far, but my idea was to optimize any exchanged message or sentence for a 4x20 LCD display, so that an arduino client could be easily coded. In fact, I liked the idea so much, that I already wrote a server prototype, as well as the arduino client. I gave this project the name "C0ldWater". The client is based on an arduino board, which uses an ethernet shield for internet connectivity, a 4x20 lines LCD display as an output device and a ps/2 keyboard for user input. I also bought a VPS, on which I run the server and a blog. You can reach it at www.c0ldwater.com and you will find all information and instructions to build such a device, as well as all code to be downloaded. So why am I posting here? Easy question, so here's my easy answer: because I already went through a first sort of alpha testing on my own, but I still need some help from anyone who's interested in this project, to get some feedback about his/her personal user experience in order to understand what sort of modifications I eventually need to implement. Nothing difficult or boring, just connect to the service and use it as a normal user: register, read, send, forward, delete or list messages and so on. I'd like to receive any suggestion, criticism or just your first impressions about the project. For those interested, but without the required hardware, I also wrote a simple linux client that can be downloaded from my site. It just creates two threads, one for receiving and one for sending data. Anyway, if you're still stacked with the win OS, you can download "netcat" and use that to connect to c0ldwater: "nc c0ldwater 8889" or "nc 220.127.116.11 8889". Thanks in advance to all of you! Cheers

After being on instructables I have notice that the rating system is a five out of five system without a way of getting any indication to why the vote count is high or low, On sites like deviant art if you want to rate a drawing the artist has to turn on critiques in which you have to give a 100 word paragraph with a rating on why it's bad or good, so on a site that glorifies Tom F**KING Preston we should have a better system for ratings. Having a requirement to write well thought out critique or reason why the voted low on something will not only discourage those who go around down voting everything because there jealous or because they want to make there chances of winning a contest higher is silly, it will also help to improve the quality of the instructables by getting proper feed back on what to fix in the instructable. Have the comment and ratting together with a little fair or not fair button with the comment.

So a lot of changes went up on the site today. A lot of it is covered here by frenzy. One that you might not notice at first is that the commenting system has changed. Instead of comments branching out with replies to replies to replies there is just the parent comment and a line of replies after it that are all indented the same amount. I'm a huge fan of the change since long conversations with multiple commenters got very confusing and very far to the right. This is cleaner for sure. So have you had a chance to see it in action? If so, how do you like it?

I work on jets for a living and there are many times that we are stuck on the comm system for hours at a time running up operational checks. What I have done is taken a female and male comm jack and spliced in a headphone jack so I can listen to music. It works fine when I am not plugged into the jet, I can hear the music in my head set. But what I want is to plug it in to the comm system and have everyone on comm hear the music. So here are the two problems I have "they should have the same answer" I need the music playing in my headphones not to travel back to the source and I need the music I pipe into the mic end not to turn my mic into a speaker. I have a basic understanding of electronic principle so is all I need 2 diodes? Just looking for some help.

Any computer you have access to the 'console' or CPU you can logon and see all the files...without passwords.Let's address each level of security:A) BIOS passwords-Remove small battery from Motherboard and wait a few (10 min) for the capacitors to drain (unplug CPU). Then reboot. During reboot or at BIOS Password screen find BIOS make/version (Phoenix/AMI etc) and download a "Flash" BIOS update to USB or floppy.-Use floppy to flash BIOS and bypass, modify BOOT path to add USB-No floppy drive? boot from CD/DVD (ISO image...see instructables)B) Login/Password:Never hack what you can access. Boot from USB/CD-ROM and load your OWN OS from these devices. Login to your OS and "mount" the systems root disc, C: drive or other partitions.Browse all their files....C) Encrypted files (EFS)Easy ! see http://support.microsoft.com/kb/255742/en-us and backup their private key, run EFSinfo.exe and set your NEW OS to the same Workgroup or Domain as the target. Then browse the files.Any ideas protection or passwords that can block this?D) Linux/UNIX is secure!UNIX & linux systems simply change their Init levels to boot as root recovery (standalone/Admin/Single User = init 1) recovery console allows access to Boot options, load CD/USB OS boot and mount original file systems. Browse or add login to /etc/password and login or telnet/VNC/SSH etc...DoneProtect your console! Lock & Block all USB, CD & DVD access.Use dongle or hardware key!Use NON-OS based encryption and PGP or DES standards!good luck

In this sketch you will find that I have attached 10 shake flashlights on the both side of a balanced seesaw system and this seesaw is moving with a 6 volt motor but I have used 10 no. shake flashlights and each flashlight will produce only 2 volt as a output which will be less than input . On the first hand each flashlight is producing only 2 volt and on the second hand the total 10 no. flashlights systems are producing 20 volt . If we try this concept than input is more than output but if we add total output then it is greater than input. please answer me that will these flashlights will be light up or not as mass is not an issue in this device. Note(1)each flashlight is separate with another flashlight . (2)to move a balanced seesaw there is need of less energy or input. These flashlights are mounted permanently ,horizontally on the both Arms of a seesaw(making+ symbol and view my sketches) and this seesaw will move side to side just 2 to 4 centimeter only.remember we will only shake the only one arm of this seesaw with corner and flashlights will not slide as these are mounted permanently on the arm of this seesaw. suppose if a flashlight require 10 watt power to glow up then we will have to apply 20 watt so that so that this 20 watt input could also counter some mechanical loss also.but this 20 watt input will be sufficient to glow up these 10 flashlights as all flashlight are permanently attached on this seesaw so each will shake with equal force or applying force will be equally distributed in these flashlights..in other words we are giving 20 watt input and out put is 150 watt with these 10 no. flashlight.we can do it with our hand power to test it to shaking the seesaw.

Restore points are always created by myself and the computer. Not once has restore worked on this xp home system
As you have all noticed, Instructables has recently implemented a new rating system, based on stars (insert 2001 A Space Odyssey joke here). We've done a bit of experimenting -- and reserve the right to do more in future -- but it's stable for now so here's how it works. UPDATE 2010-09-24: The below calculation has been tweaked to bring Instructables' ratings closer to the level of ratings of comparable content on the Internet generally. We found that we run about a star low, based on a rough look at a bunch of other sites and our (totally unbiased of course!) estimates of their content quality. So, we have added a star to all ratings across the board. It's like grade inflation... but we know our users put up really good stuff and we want that to be recognized. UPDATE: we've tweaked the system a bit more. The below describes the rating system as of 2008-11-15. The rating system uses a weighted average, where Instructables with only a few ratings, or ratings by users who have not rated many Instructables, have a total closer to the middle of the star range than the actual average of the ratings. For example, an Instructable with one five-star rating will have a total closer to 4 than to 5, because there are so few ratings on it. If the user who rated it hasn't rated other Instructables, the total will be lower than if the user who rated it has done a lot of rating in the past. The purpose of this difference is to minimize the effect of 'shill' ratings; we've seen some members attempt to bump their ratings by creating fake accounts just to rate up an Instructable or two! As more people rate each Instructable, the total becomes closer and closer to the true average of the ratings. And as each user rates more and more Instructables, we weight their rating higher and higher. We have done it this way because we want the rating to reflect the opinion of the whole community, and we believe that members who do a lot of rating have been around enough to have a good sense of what makes a good Instructable. Also, members who comment and rate have their rating counted higher, as the comment indicates a higher level of involvement with the Instructable than rating alone. This method makes it so a less-than-stellar Instructable can't be pushed to the very top of the ratings because the author got their friends to sign up and rate it at 5 stars; similarly a really good Instructable can't be dragged too far down by a malicious user. For the mathy amongst you, this is the formula (we changed the way one component is calculated): (siteAvgNumRates * siteAvgRating) + (numRates(ible) * avgRating(ible)) R(ible) = ---------------------------------------------------------------------- siteAvgNumRates + numRates(ible) The avgRating(ible) is no longer a straight average, but a weighted one. It's calculated like this: (W1*R1 + W2*R2 + ... + Wx*Rx) + 2(V1*C1 +V2* C2 + ... + Vy*Cy) -------------------------------------------------------------- (W1 + W2 + ... + Wx) + 2(V1 + V2 + ... + Vy) Pretty complicated algebra, huh? W and V are both weight values, between 0 and 1. R is the rating of someone who has not commented, and C is the rating of someone who has commented. siteAvgNumRates and siteAvgRating are estimates, held constant in the pursuit of not having ALL ratings change every time one person rates one Instructable. As you can see, when the number of ratings for a particular Instructable is low, the weight of the site averages count for much more of the rating value. When the rating count is high, the site averages are only a small part of the total rating value. We believe this algorithm has a good balance between letting the cream rise to the top, and preventing 'rating spam' to coin a term. Please comment!

Dear Fellow Forum Readers, A while ago, I posted an idea/request asking about the possibility of making the names of Instructable PDF files conform to a certain standard for ease of filing. I found my own best solution. If anyone can use this idea, please do! What this project does is to add symbols to the titles of instructables which indicate awards and featured status for each downloaded Instructable. I am using a Mac and purchased the app "A Better Finder Rename 9". Within a parent folder entitled 'Instructables Downloads' I created a group of folders with the symbols corresponding to the featured/awards symbols of the given Instructables. For example, if there is one star for an Instructable, I designate that this way: (*). If there is a star and a goblet, it is designated like this: (*+). I make a folder for each of the combinations of stars and goblets and then as I download (I download many at a time) I just save them to these folders. Then afterwards, I use "A Better Finder Rename" to add the designations as a suffix to the Instructable titles. When I want to quickly pick out the most awarded Instructable out of several options for a given project, I can see right away which one is most recognized as excellent. Finally, I made a master Instructables folder with broad catagories within which to sort my downloads, e.g. Electronics & Computer Instructables, Maker & Prototyping Instructables, Gardening & Homesteading Instructables, etc. Now I have a nice library for portability and offline use! Will many people want this? I doubt it. But it makes my substantial collection easy to go through and saves time when I want to look for recognized excellence among many choices of projects. Besides, it's fun and 'therapeutic' for me to idly sort, rename and file these great projects on a lazy afternoon (not enough of those!). Helps me mull what I'll work on next, too. :-) TN
