*SOLVED* Contest / Challenge entries limited to one submission? (Yes)

Good morning,I finally found time to create a new Instructable, and there happen to be two challenges my project would fit. I entered one, but when I tried to submit the same Instructable in another challenge, the system would only pull from my draft folder, and not active projects. Have the rules changed, that only allow entry into one contest or challenge?Many thanks.

Important Changes to Contests - May 1st

Hello everyone! As most of you have probably noticed, we haven’t changed much with our contests over the last several years. But this year we’re changing that, thanks to all of you and your important feedback! In 2018, we are going to be trying new things when it comes to contests. We believe these changes will lead to a larger variety of winners and even more incredible instructables!With that said, we’d like to announce two major contest updates starting on May 1st. #1 - Every instructable can only be entered into ONE single contest.At first, this may seem like bad news, but we promise it’s actually good: the new rule will allow more authors to win prizes! We’re reducing the number of prizes ONE instructable can win, but this will allow for more winners overall. While we’re sure some of you will be disappointed, this is a great way to level the playing field and simplify the process for both authors and judges. The old contest system allowed an author to enter three contests with one instructable, which greatly increased the number of entries per contest. Along with increasing the number of entries per contest, the old system tended to pit new authors against much more experienced authors who understand that they can up their chances of becoming a finalist by working multiple contest themes into an instructable. We hope this new contest rule will encourage our authors to commit fully and enthusiastically to one contest theme and create more focused projects, instead of stressing about making something to qualify for three separate contests!.#2 - We are creating more Prize Packs.Currently, if you win a contest at any prize level you will get an Instructables prize pack, some stickers, and whatever other random swag we have lying about in our prize room. As it turns out, this has created a situation in which our best authors end up filling their homes with piles of instructables T-shirts. We recognize that winning T-shirts over and over again is boring.To make Prize Packs Great Again over the next few months, we are going to roll out new Prize Packs on a permanent and limited edition basis. When you win a contest, you will be able to select the standard T-shirt prize pack, but you will also have new choices coming soon.Make sure to keep an eye out soon for new Instructables swag we know you’ll love!

Turning the volume down

I have a speaker in my office that is very loud every time announcements are given. I have permission to add a pot to the speaker to adjust the volume if something like that can be done. It's basically an intercom system from one main point in the building. If I were to do this, what size pot would be needed and would it be wired in line with the positive lead of the speaker coming in on the input side of the pot and the middle leg of it going to the speaker? Thanks in advance for reading. There's a picture of the speaker doesn't look like anything fancy.

What could it be? Car died. I lost all compression on all 4 cylinders in my car ?

This is a 2000 Dodge Neon 4 CYL 16 valves,SOHC engine. Ok. On oct 1st I was driving about 60 mph for about 6 minutes after leaving my house in the morning I heard a noise that sounded like a pulley belt then the car turned off, pulled over to a parking and checked to see if a belt broke and they both were there. I checked the timing belt still on. try to start it and the timing belt look to be ok and turning. I did notice that when cranking it sounded weird like it had no compression at all at the pistons. I towed the car home checked the compression an all 4 cylinders and I was right I had no compression at all on all 4 cylinders. I see the timing belt turning when I crank it so I know for sure that it can't be the timing since the belt was replaced MAY, 2009 when the water pump went bad along with a new pump and rebuilt head w/brand new valves. I'm not sure what 's going on all i know is when I crank it the timing belts turns, the pulley belts all turn fine. This is the first time I had this problem. I fix all my cars but this is a first for me. If anyone has any idea what could it be I appreciate your help. I just spent a lot of money on this car so I need to have an idea before I start pulling it apart after installing a new head gasket set with all the new parts. THANKS

Old instructables in featured page Answered

I see you've bumped up old instructables to the featured page - can we get some information about why is this happening? I mean, I think it's a good idea since the number of quality insutrctables has been lower lately, and most of us probably didn't see those old instructables anyway. Still, it would be nice to get some explanations :)Thanks!

How to add magnets to magnetic resistance exercise bike to increase resistance?

Hi, and thanks for reading my question.      We have just bought an exercise bike, it uses the pedalling to power the magnetic resistance of the bike. Here is the problem: at the highest setting, the resistance is still not very much.  We think that maybe we can increase the resistance by putting a strong permanent magnet near the flywheel, (we would cut a hole in the plastic cover to put the magnet near the flywheel). Can someone explain how to figure out how strong a magnet would need to be? How much "pull" would probably have a significant effect? What type (neodymium?), and what shape would work best (disk, rod, etc...?). We are willing to put about $50 into a magnet.   If this doesn't work I think I will remove the cover and just use a "friction wheel" sitting on top of the flywheel. really ugly, but it should work. Thanks for any help you guys can give!

Could Instructables please stop altering the aspect ratio of our photographs?

It's an unwelcome change to the Instructables format, that images we upload are being stretched in one dimension to fit into boxes. I can live with all the images being at the start of each section instead of embedded inline, but stretching a picture is *never* acceptable. It makes the site look completely amateurish. Please use a better box-packing algorithm or allow us to slide the image around to fit, but don't ever stretch to fit.

About this curtain control mechanism

In the following, weight of the bottom pulley is used to create tension for the cable. What happens if a timing belt is used instead? Would such a setup still require the top 2 pulleys on the right side? I think it would become a lot simpler. One pulley on the left, one on the right. This works ? Any downsides ?

Creating a chatbot or conversation robot.

Hi everybody.  I have a quick question I would like to throw out there and hope somebody can help. I am in the early stages of making an autonomous robot and one of the functions I would like it to have is the ability to hold a conversation with people. I have made a previous cardboard robot as a proof of concept for my next build and used an iPhone chatbot app which worked quite well, but I would like to make my own stand alone chatbot.    I am aware of the likes of "Pandorabot" and "Cleverbot" ect, but what I would love to do is program my own stand alone chatbot using the available hard drive memory on an old laptop I have laying around collecting dust, and use the Windows xp voice recognition to talk to it (speech to text) and have it respond with a spoken voice (text to speech) which would come out of a Bluetooth speaker located in the robot. I know my way around a computer to some degree but do not know how to program (although I did follow a program written down once to make an  analogue clock many moons ago), but with some hopefully straight forward instructions I am willing to learn and give it a go. I have a rough understanding what AIML is but don't know what I would need to use it. I want to go down this road as I want to have it off line, i.e not have to rely on an internet connection, except maybe my home network to connect to another device, not to rely on a second party server, and would like to put the old laptop to some use.  I know I bit about teaching or training a bot to respond, i.e, giving multiple phrases or questions with one meaning (eg Hello, Hi, What's up, Hi there ect,) and the bot to recognise and respond accordingly, and I'm aware it will be time consuming, but it's the basics, or starting blocks that I'm after, getting a bot up and running and ready to be taught or trained, and if it's something I can get my head around and it's something I could realistically do, I would love to give it a crack.  So, Is it reasonably possible for me to use my old laptop for the sole purpose to use it as a chatbot, what would I need to set this up, Can what I need to know, be broken down in to easy to follow steps for me or anyone to follow who does not have experience in this field, And what recourses are there that I could use if needed? Any help, thoughts and suggestions that anyone can offer to get me started on this idea really would be greatly appreciated, and may be of help to others too as I have not seen this sort of question asked anywhere on the inter web in regards to just using a home computer / laptop. The only information I can seem to find relates to online bots. So thank you in advance for any help offered and I look forward to any responses. Steve.

DIY Solder Pot

Just today, my brother offered to give me his old coffee maker that he had replaced with a newer one. He is well aware of my electronics hobby, which is why he offered to give it to me in the first place. Nothing is wrong with the coffee maker electronically - he just didn't use it for a long time in which it became moldy on the inside. He cleaned the inside properly, and as a precaution I did it a second time. Now that it is cleaned, I'm curious as to if I could turn it into a solder pot. Seeing plenty of DIY solder pots, I'm thinking I could use an empty soup can, cut to a reasonable size, and have it rest on the heating element of which the coffee pot would normally rest on. Would I be able to do just that or no? Any suggestions as to what to use for the "bath" or "pot" of which will hold the molten solder? Thanks in advance! P.S. This is a basic electric drip coffeemaker I'm wanting to salvage - just to clarify.

Can anyone help me with correct wiring for an IH circuit I'm building?

Hi all! I'm working on building an IH and I really need help with getting the wiring correct in my circuit. Parts I'm using:-12v - 10a power supply-12v IH circuit pin halo latching momentary switch (to be used to control power to the circuit);=1-6 pin halo momentary switch (to allow on-demand use of the IH circuit to prevent inadvertent overheating) wireEssentially, as somewhat stated above, I want the incoming power to be controlled by the latching switch and the power to the IH circuit to be controlled by the momentary switch, activating the heater on demand. I've managed to get the latching switch to light when pressed and I have the momentary switch wired to the latching button so that it lights when pressed. I cannot, no matter how many reconfigurations I've made so far, get power from the momentary switch to the IH circuit as I'd hoped. I'm happy to provide imagery as well if that would be helpful with the above information. Literally, at this point, ANY help would be so very greatly appreciated. I've been at it for a few evenings now!

Using Arduino and 8 servos!? What type of power source? Answered

Hey Arduino guys! I got a question. I am using 8 servos with my Arduino. All the servos are hooked up parallel to the 5v and GND on the Arduino. All the control wires are hooked up on pins 2-9. I'm using 6 AA batteries as my pack. Is this OK for my Arduino? With all these servos moving at once, I want to make sure I'm not frying my board. Oh, and, got another question. The 6 AA batteries are too heavy for my robot spider, so I want to use two 9v batteries instead. But, this delivers 18v. Arduino and only go up to 12v. So, what can I use to bring my 18 volts from two 9v batteries down to 9v or 5v? What can I use? A voltage divider with resistors? A voltage regulator (whatever that is :P)? Thanks guys!

Program or script to change volume...? Answered

Another question that is way out of my league (woe is me).  I need (or rather want) a program, in either Java or VBs (if there's a better one like Python or something, that would be alright too) to change the volume of a Windows computer.  It would also be a good showcase of your skills to make it able to change the volume of a specific program or application.  The way I intend to use it is as if it were a function, rather than a program. So a different script will activate it (perhaps by writing it, which in Java I don't think is possible) and then set the volume and the program to change the volume of. If that can't be achieved, could it be made to read a text file (or something else) with two lines on it; the first the program, the second the volume. If the first line says something like none, It would change the volume of the whole computer. Hopefully I've given you a good enough description to make it clear exactly what to do. Thank you in advance.

2Kw photovoltaic system dedicated for electric hot water heating with DC only -teething issues.

Hi instructables people. Took a chance and setup a photovoltaic system directly wired to a hot water element. The issue is that when first switched on in full sun, power output is 1900ish watts. Great! however the voltage very slowly drops down resulting in 1600w over an hour then settles. I change the resistance of the elements around 1.5kw for instance and it happily stays at 1600w without too much deviation not including weather conditions. I know it is volt drop thats going on here but really need someone else to help explain whats going on to me. I really am hoping to use 2kw as much as possible. Much appreciated.
