ROOM : SMART

Ok I was sitting at the end of my bed listening to my music (I plugged my psp into my stereo) and I had an idea make my room smart. For example door opens light comes on. I could even make it a security thing. But also I have about six things in different places in my room and they all need to plug into so maybe would make a little switch box/control unit. So I was wondering if you could make your room smart what would you want it to do ?hmm maybe i could make my MICROFROSTEY (mini fridge. (soon to make an instructable on it)) somehow work with this....AND YES I REALIZE A SMART CAR HAS NOTHING TO DO WITH MY ROOM ! ( I just googled SMART and thats what I got)

Ravens are Smart

Check out this article for a really neat description of how and why ravens are smart. Basically, it's a great trait for a scavenger to evolve- they need intelligence and what amounts to a rather sneaky form of empathy to snitch lots of food from predators and hide it from their fellow ravens. Good stuff.Ravens can toboggan, ride other animals and spy on their enemies. Their life as cadgers stealing prey from wolves, eagles and bears has made them outstandingly intelligent.

Metro Smart Watch

I had an idea the other day whilst playing Metro: 2033, I imagined a smart watch made like Artyoms watch but instead of having an LED come on when you're visible, having an LED linked to your phone that comes on when you have a message like an external notification light and wondered if there's any way to make this a reality?

Smart battery charger

I am trying to build a smart charger that will charge a Ni-Mh 2/3a 1200mah 9.6v charger. By smart I mean that it will stop when the battery is full, then if it drops below, say 9.4v, it will charge it to that again. Most of them also have a discharging button that will bring the voltage down before charging it. For the charger part I found this websitehttp://www.elecdesign.com/Articles/Index.cfm?AD=1&AD;=1&ArticleID;=1823Which details how to make a charger that will charge a 13.3v battery. Of course, mine is 9.6v, so it would have to be modified. The current "dumb" charger for the battery just gives it 12v @ 250ma. The smart charger also is powered off 220vac, which is not good because I live in the US. IS there a way to make it work off the 12v 250ma charger? Also, the circled components (the overlay thingy wasn't working), what are they? the no/nc one might be a switch, and the RL1 one could be...a relay?

smart window thermostat

Wanted: circuit to open window at night when it is cooler outside than in. Close it when hotter outside in morn. Probably add something to prevent it from opening and closing several times in the eve and morn with random fluctuations. Prefer 2 thermostats, 1 outside, one in, rather than a timer. I've a vague recollection of a circuit with 2 potentiometers, one on the motor, one on the control panel, such that turning the control pot will activate the motor until its pot is at the same position as ctrl pot.. Could a circuit something  like this control my window? But most thermostats are on/off, not continuous variable.   It would be simple to do a switch logic thing like:  “IF thermo ‘I’ is above 70 AND thermo ‘O’ is below 70, THEN OPEN “  but that only works at 1 temp.

Smart board Using distance meters.

Hello! My name is Muneer. I was wondering whether this concept of making a smart board would work(shown in image). The idea is to use two distance meters to measure distance ‘a’ and distance ‘b’ from the transmitter in the pen to the top corners. Distance c is fixed and known. Using the distances, the x and y distance should be workable from the formulas(shown in image) I guess. I have a few concerns and require your expert opinion, a. How can we construct the distance meter (IR? Ultrasonic? Any available schematic...etc) b. Converting the x and y distances to pixel information c. Interfacing the board to a computer, possibly giving the input from the smart board directly as a mouse input. or if you could suggest other practical ways. Could you please help me with this? Thanks.

Bluetooth Water level for smart phones

I want to know how this would be accomplished PLEASE. Looking to make a bluetooth system that sends water level of a tank to a smart phone. I would think the most cost effective way to do this is by using a bluetooth module and float switches. The module would send three levels full, half and empty, so say all float switches are triggered it would be full, only one it would be half and if none it would be empty. What do i need to build this.

Help with JARVIS-like Smart Home

Hey guys, I am planning to do a project with Smart Home theme. I would like to create JARVIS-like application, which would be able to recognize my voice and then do appropriate action. Example: Temperature Sensor Me: "Jarvis, Show Temperature" Jarvis: -"Temperature displayed sir" I am planning to buy a very cheap Tablet, on which I would like to write an Android Application, which would create "jarvis" and other activities. For example, if I say "Show Temperature" the activity would pop up, where the temperature will be displayed. I will messure temperature with a Thermometer (DS1280 most probably). And I'd like to use a Bluetooth module to communicate Wireless with them. Temp. Sensor -------- > Arduino board ------------> Tablet All of the above are on different locations. I need help with this project, so if anyone could do an instructable on how to do this - would be really awesome! What do I need ? - Temp. Sensor - Bluetooth Module - Arduino Mega - Speech regonition software (BitVoicer probably) - anything else? Also, is the TFT display (http://www.geeetech.com/wiki/index.php/3.2TFT_LCD) good enough to replace the Tablet ?  Meaning, can I write such an Application to this display ? Thanks, David

Image Deletion- "Well that was a smart move."

Well that was smart. I thought for the first time, I would have a clean out of my image library. I apparently have never noticed before, that your image library is directly connected to your I'ble pictures. I assumed that after you had published an I'ble, that the images in it would be stored. I guess I was wrong... That really really, does not make me happy. I'm just hoping I have some of them saved on my computer, because that little effort just wiped at least 3 of my I'bles... Luckily I was getting a server error so I stopped deleting them after the first 70... I know it's my own fault, but I can't believe I have never had a conversation or heard about that before. I have no idea where to start now, I guess I should un-publish all the I'ble's.

Calling All Good/Smart Knexers

Note: When I address 'ibles, I'm talking about the K'nex community here.Hey, knexers of 'ibles. Ignore my title, but it was irresistible , was it not?I'm here before you all today to give you all something to ponder, or act on. Yes, this is about the K'nex 'ibles and KI dilemma. I'm going to tell you now, I'm not going to flame 'ibles, or put offense upon it. Instructables is a DIY website, not specific to K'nex. It wasn't made to hold this community. In my opinion, people here care too much about things they shouldn't , such as ratings. People can rate them anything they want. "5 star because it looks cool!" "1 star, I don't like you." I haven't seen a lot of constructive criticism, which is, I think, what everyone should want. Most of the comments I see aren't very pleasant to read; do you really need to say "u" for "you"? Or "thx" for "thanks"? There aren't many rules here to enforce this. Or if there are, it's too laid back.First off, as you can tell by the name, K'nex Innovation was started for the productivity of K'nex. The decently small community there uses good grammar, to a point. It is moderated better post wise, as it is focused on one topic and things can be easier checked, for its size, once again. Another reason for this is that it's focused on one thing, and one thing only, so that there's less people than Instuctables obviously has. I'm not saying the people on KI have perfect grammar, I don't have it, but I'm saying that they try to the best of their abilities. No rating system. We give constructive criticism, and look down on "OMG COOL GUN!!!!1!!!!11!!" type posts. If you want to say that kind of stuff, PM the dude/man/guy. There's a mixed variety of people; gunners, and then some that make other nifty contraptions.There's a chat room, for K'nex talk. Of course, we have fun there too, throwing off jokes and playing around. Usually a good 8 or so people are in there. A handful of the more matured users who once roamed this site have settle there, such as Mepain and Oodalumps, to name a few. Recently, people there have started a podcast, currently with only two episodes. Also a step up in the community (coming from K'nex Innovation), soon there will be the first internet organized K'nex war.Even if you completely disagree what all that I said, please go check the site out: http://knexinnovation.net/And for those of you who want to talk it up with us first, here's the KI Chatroom: http://embed.mibbit.com/?settings=d4a2e2317b84e8897df0b736464a8ee4&server;=mibbit.darkmyst.org&channel;=%23KIchat&

RFID or Smart Card Cashless Payment System?

Hello! I was wondering if it was possible to make a cashless (apart from adding funds) payments system. I was thinking it could be done with an Arduino and RFID reader/writer OR smart card reader/writer. The balance would be stored on the card (AFAIK data can be stored on the cards) and when the person buying something wanted to add funds to their card, they would hand over money. The person that is staff would type in say 500 for £/$5 and press a button, the user would then scan their RFID tag/card or remove their smart card (because I forgot to mention that they put it in at the beginning) and the funds would be added. If the user then wanted to buy something, they would say what they want, then if the total came to £/$2.50, the staff member would type in 250 and press a different button and the user would scan their RFID tag/card, remove their smart card, etc. I would just like to know if this is possible. If you need it explained differently, then just ask! Thank you!

Smart Phone face glass replacement kit

What this world really needs is a temperature controlled face glass removal and replacement kit. Most of my working friends that have Smart Phones have broken or shattered touch screens. A quick search for touch screen replacement provide a bunch of Youtube videos and DIY kits for under $20. All the vids and kits say that too much, or too little heat will destroy the actual touch sensitive surface under the glass. The only source of heat they use is a blow dryer. I already break enough stuff that is not technology that I do not understand. My brain says a flat aluminum plate with suction holes to hold it in place and act as a handle during removal. Temperature controlled that can be set to the exact temperature for easy removal and replacement without applying too much pressure on the inner touch sensitive part. The online kits offer plastic wedges for popping the glass loose when/if you get the right temperature. An exact temperature face glass removal kit with the necessary wedges or possible strong monofilament fishing line to ease the glass away from the base. Everything I mentioned is beyond my knowledge and/or skills, but DIY Instructables or even kits to help out friends in need would be awesome and probably a good source of income for the entrepreneur.
