Is it just me, or does kipkay (and a lot of the maker community in general, but I noticed it most with kipkay) have a suspiciously creepy amount of spying makes.

I am getting a little annoyed by how the layouts are always changing. And I bet a lot of other people are too. ...so I got an idea that there should be a poll, showing all of the previous layouts, and maybe a few new ones, where the Instructables community could vote and pick their favorite one. Leave a comment on what you think about this, or give some other suggestions...

I built a hotwire device to cut foam insulation. If I connect it directly to a 12 volt battery, it gets 'way too hot very quickly--the hotwire turns red almost immediately. However, if I connect the device to a wall charger rated at 5 volt/2amps, it works fine,if a little too cool for a good cutting speed. What's happening here?

Hello,I am building a multi-touch surface using the FTIR method and after the surface is powered for about 10 minutes there is a heated smell in the room, I have noticed that the resistors are very warm and that a couple have started to brown or burn. I really need this table to be able to be safely powered at least 18 hours a day.Here are my specs:LED's:I am using 88 Infrared LED's (T 1 3/4 INFRARED LED, http://www.allelectronics.com/make-a-store/category/340250/LEDs/Infrared/1.html )--8 LED's per series--forward voltage of 1.5v --forward current of 100mAResistors:I am using 2, 10 ohm 1/4 watt resistors parallel (so 5 ohms) with each of the 11 series'Power Supply:The power supply output's 12 volts DC and 1.2 ampsWhen I calculate using http://led.linear1.org/led.wiz it says I only need 1ohm 1/4 watt resistors, I haven't tried this yet but it doesn't seem to me that this would rectify the situation. My guess was that I need 1 watt resistors, but the calculator didn't seem to agree.Any thoughts as to what my problem is? is it safe to go with 1 ohm 1/4 watt resistors? or do I need 1 watt resistors? Any help would be very appreciated, thank you!

I have been looking into making liquid nitrogen and I have found one DIY method. It uses a small cryocooler. I wondered if it would be possible to use multiple stages of coolers like those used in a freezer. So basically you take all the stuff off of a two or three freezers, or more, and you use them in a series to get progressively colder. The first compresses the coolant which is then decompressed cooling the hot side of the next step down to freezing temperatures. Is this possible with your everyday freon which is already in these systems, or do you need to get a better coolant, and will this even get cold enough to liquify nitrogen?

Lately I've been seeing more and more contests which require expensive, specialized tools (mostly 3D printers) in order for you to make something that is eligible. I wish we would have less of this type of contest, or at least have people utilize tools other than 3D printers. How about a milling/turning contest instead of endless 3D printing-related contests? I'm just worried that many of the contests are inaccessible to the average instructables user, and also getting a bit bored of contests which involve 3D printers.

I have had some trouble cooking bacon. When I bought thick sliced bacon, my roommate stored it in the freezer (I think this was the problem?). The next day I had to moved it down to the normal side, took like 3 days to become pliable. However, when I try to cook it, it become so dry but I don't know why. Here's what I did, I left the slices on the pan (without heat) for 10 mins, then I cooked on medium heat, flipped till they became golden brown, then I pick them up by chopstick and leave it in my dish. First the bacon still have a little grease on it, so it's glossy; but a few moment later, it turn bone dry, no grease, no gloss, no nothing. Can anyone tell what my error was? I'm still new to bacon so sorry. PS: I wasn't able to take any picture cause my roommate ate them all because he was too hungry....

I received an email today offering a great job for what appeared to be an Australian Auto Dealer as a Regional Assistant. Basically the job consists of accepting customer's payments to your bank account and you forward, less 10% of what you received via Western Union. The web address they gave for the job position is http://vacancy-3967781.scarcentre.hk/vacancies.php (notice how it's in Hong Kong). This is a fraud! Yes, you would receive the money, and make the 10%, but you would be participating in a Libyan Identity Theft Ring. In a short time, you will be caught and you will be fined or incarcerated for fraud. They don't care because they'll find another sucker tomorrow.What the job actually consists of is laundering illegally acquired money. Since the money actually stops at your bank account, you're liable! Don't let these thieves use you! This is literally an attack on the people of the U.S. stealing Billions of dollars every month from fellow citizens. Please, don't help them.

Hi, I'm trying to figure out working with shift registers. I bought a couple of 74HCT4094's, hooked them up through my breadboard to a small matrix with some LEDs and my Arduino. Without multiplexing everything works fine, but no matter what circuit I build (changing wires, resistors, transistors, even the Arduino code), when I start to multiplex the LEDS clearly 'flicker' (is that the correct term?). Is it possible that some shift registers are 'too slow' for multiplexing with Arduino?

Hi guys... Ok, I was posting this asa comment, then I remembered the "be nice" rule and thougth about setting things in a positive way. AIM: I like instructables a whole lot. I come here EVERY DAY for inspiration and help in many things. So I whant it to remain the nice place I think it is, full of creative people that solves everyday problems and improves lives of other with the power of theyr brain and hands. In order to keep this I thing it is important to keep things "brand free". COMPLAIN: There are too much questionable sugru instructables around, Let's face it. Some of them are real innovative and clever, but much of those are daily and"not that usefull" at all. The point is: aren't those qualifiable as COMMERCIAL ADDS ?? I mean... I like that thing, but are we sure that there is nothing irregular going on? Thanks

So here da ting. i got a little 6v power wheels quad at a yard sale for dirt cheap. i figured hey why not ill work on it a little and make it nice. long story short, i ended up with two 18v harbor freight batteries hanging on each back fender like military ammo cans and it looks awesome but now its a little too scary to let my son ride it. i would like to put a voltage regulator on it to turn it up or down depending on how well he can ride it and how safe i feel he can be. most of the ones i have found can barely handle 2 amps. where can i get a regulator to handle the load continuously. p.s. this is the last part i have to figure out before i can make a full instructable.

I'm getting started with Stepper motors and I got one on ebay, it's MINEBEA NEMA23 2.5V/1.8 AMPS 1.8DEG/STEP (model# 23LM-C045-01H). I'm a bit confused by it's low voltage. Am I reading it correctly, it's 2.5Volts? Stepper driver that I have requires at least 8 Volts (it's Arduino with rugged motor driver shield), so is it safe to drive with motor with voltage of 9 or 12 volts? How would one drive such motor at 2.5VDC?

Here's an image that's been making the rounds today. It's a bed that breaks down into four pieces that can then be interlocked with the floating bookshelves to form some sort of padded wall/bookshelf. It's just a design concept and not meant to be produced (I hope), but even so it's quite a case of a design looking for a problem. A few shelves on the wall will have a lot more storage for books and you can then store a futon or an inflatable mattress underneath. And do you really want your mattress displayed on the wall?

A friend showed me this trick at Safeway. If you are thirsty, but either 1) Don't have money on you or 2) Don't want to buy a whole bottle just for a few sips, most food stores are required to give free water to anyone who asks. There will be no signs advertising this fact. Simply walk up to the counter (we did this at a small Starbucks stand by the bakery) and politely ask for a drink of water. My friend received a clear plastic cup filled with water and ice, no charge. Then I walked up and bought a Dr. Pepper, not free of charge.

According to the circuit I need about 6 volts input to run a luxeon star LED. As I understand it, the regulator takes about 3v leaving 3v for the LED and will will provide a fixed current of 320ma which is just fine. My question is, can I use a higher input voltage such as 12v without affecting the luxeon star? Although the current output is fixed, will the output voltage rise as the input voltage rises and burn out the LED?Image reference http://led.linear1.org/a-cheap-current-regulated-luxeon-star-driver-design/1/TIARichard:)

I have double pane, insulating glass house windows that collect condensation during the winter heating months. The condensation is not between the panes, it is inside the home. The water builds up and runs down onto the wood frame causing rot. It occurs only on the bottom inch or two of the window. The home is in Northern Wisconsin where it is commonly 20 deg F outside and 70 deg F inside. The interior humidity is controlled and not excessive. Aside from setting the interior humidity to desert-like conditions, how can I remove the moisture and prevent further damage to the frame? Desiccant bags? Solar powered fans? Any ideas would be greatly appreciated.

Hello everyone! I am trying to build an arduino RF remote control to clone my remote control for my wireless sockets. I bought this RF module from ebay http://www.ebay.com/itm/New-433Mhz-RF-transmitter-module-and-receiver-link-kit-for-Arduino-ARM-MCU-WL-/140847542952?pt=LH_DefaultDomain_0&hash;=item20cb2af2a8 At first I thought it was damaged because I wasn't getting any signal from the reciever. After many tries I touched the reciever with the remote and suddenly I got the codes (I want to recieve the codes, save them and then re-transmit them with the arduino). The same goes with the transmitter - the only way it works is when I hold it against my wireless socket. It means that the codes work but the signal is way too weak. I tried hooking it up to different power sources- Arduino 5V, Arduino 3V, 12V 1000mA Adapter, and the original battery of the remote that states 12V 23A. I tried making an antenna but nothing really works.. please help! thank you..
