How can I make a single LED lite which can be placed in windows of a remote house to appear as security system in place.

We have a remote house under construction.  I've been trying to find a way to have a tiny LED installed in the inside part of the window frames to appear that an alarm system is in place.  We have cameras in place but this would be just another layer for the crook to decide if he wants to go further. The house is closed in and dry.  There is 120v available.  If it is possible, I'd like to have a "socket" at each location for bulb replacement.  It can be low voltage with a transformer and it would be better if all the lights were on the same loop.  The loop would be about 100' and 8 windows. If the only way is a individual LED powered by some tiny battery, that could be OK if the life is quite long. I could fabricate a housing to hide the battery or socket so only the light appears. I'm also trying to figure out how to making a single flash LED which I will post as another question in the same category. Thanks very much, GTinWA

Need Security Light Help Please

I'm trying to set up some security lights and I'm having some trouble. I don't really like the motion-sensor-activated lights that I've seen -- they all have the motion-switch right by the light -- I'd rather have them come on when either of two gates are opened (if a person is coming from the street) or if someone passes a spot on the walkway (if they're coming from the back building on this property) either with an eye-beam or, if it's cheaper, a motion detector, that's nowhere near the lights. I would like the lights to come on only at night and go off after about 5 mins. If possible, it would be nice if a noise could be played during the daylight hours. I've looked into delay timers and other devices but I'm really new to this, so any help would be appreciated

Wiring motion sensing light to include a 120V AC siren?

Here's the goal: to have a wired, outdoor, motion sensing flood light that includes a 120V AC siren that will also sound whenever the light is triggered.  The proposed setup would start with some sort of switch or hidden switched outlet (possibly WeMo so only I can control it and I can also tie in some IFTTT recipes) that the whole system would run through.  Power would then run to an off-the-shelf motion sensing flood light not unlike this one.  From there, one of the light fixtures would be rewired to run power to a 110V AC horn/siren not unlike this industrial unit.  Is there any glaring reason that this would not work, and what considerations should be made vis-à-vis the fixtures wattage rating and the rating of the siren?  The final product should be something that when switched off is just, and when switched on would trigger a light and a very audible siren.  Finally, any ideas on where to look for a siren/horn like the one described?  The industrial unit in the link might be a bit too big. fdsafdsa   fdsaf(not un From

DIY Motion activated security camera

Ok i like the idea of where you put a security camera in a hidden spot around the house to capture those unwanted trespassers, but recording unwanted recorded video from the the night you were on vacation sometimes is a pain to watch since you have to watch the whole thing or fast forward to the part where someone came "unnoticed" (especially when you have some people in the neighborhood egging your house). anyone have an idea where a standard security camera (mini cameras, cctv, wireless w/ IR lighting) can be hooked up to a computer (or better a stand alone hard drive) and able to use a motion detector and also only record video that shows "someone" on the property when activated?

How can a LED be flashed like a strobe, motion activated and installed outside to act as a security light?

This is about home security.  I have posted another security question on single LEDs in the same category. We have a remote house under construction at the end of a cul-de-sac.  My idea was to create some type of motion-activated single flash strobe or LED burst of light.  This light would be installed at the cul-de-sac and the motion sensor could be further away.  I just want to create this big flash so that any one coming around in the wee hours has to decide if they just had their picture taken and do they want to go further.  The strobe would just flash once like a camera flash, not flashing repetitively. So the final product would have to be weather and water proof.  The house is about 200' from the cul-de-sac but there are a number of empty, underground PVC conduits run from the house electrical panel which could be used to run out 120v or low voltage wiring. I've looked everywhere on the net.  The closest I could find were cameras that are made to take flash photos of animals at night and are motion activated.

Hack my homepage?

Software security issues are often obvious to a second pair of eyes. I just posted the PHP scripts for my personal contact homepage as an instructable:Simple PHP personal contact homepage (web3.0!)Can you hack it? Preferably a copy on your local machine and not on my actual server... I deleted all my administration files and classes prior to making this post, just in case.I have two primary concerns:1. General PHP injection attacks. Proper handling and escaping of form data.2. The admin interface has a sessions based authentication mechanism. Login is compared to a MD5 hash of the password, then a session is created with an MD5 hash of the user's IP address. Each subsequent page load compares the authenticated session IP with the user's IP address (again, an MD5 of both). The goal is to prevent remote session stealing related flaws by tying the session to an (unknown...) IP address. Obviously if you have access to the local machine this is all moot, but there is little I can do about that. If an intruder were to get around the session authentication, they would be able to upload files just about anywhere on my server using the admin upload interface. This is a bit of a concern...I think in light of this, I'm going to add an option to limit the web admin interface to one IP address. My IP is fairly static, and if it changes, simply upload a new config file by ftp.

Arduino Outdoor Security System - PIR Motion Sensor, Security Lights, Intruder Warning/Alarm & Blynk Notification

I would like to ask your suggestions on how to build an outdoor ESP2866 security and sensors combo. I have seen separate postings on PIR and lights around the site and in other websites so I thought it would be doable. I knew Arduino then but only paid close attention when I realized that my x-10s are outmoded but z-wave devices are expensive. So I am learning about it, how to sketch and trying to understand C++ more. My dream is to build an outdoor ESP2866 combo, powered by an AC120v-5v module, with two PIR motion sensors, three 120v relay switches (two relays for two sets of security floodlights and one relay for an amp/wave speaker with mic), a photo (dusk/dawn) sensor and temperature/humidity sensor (for a future thermostat). Operationally, I imagine that it could be armed and disarmed through Blynk. When armed at daytime, a motion will trigger a low volume intruder MP3 warning alert with 10 minutes of security lights at night. But if the trigger persists for more than 5 minutes, the security floodlights will blink, a loud intruder alarm will sound and push phone notifications. What will be the best way to sketch these? What is the better way of wiring them together? How could I make multiple ESP2866s in the same WAN work together for an event? The desired function is if an alarm event is triggered in one of the ESP2866 that would also set off blinking lights and alarm sounds in the other ESPs. Thanks for all your help.

Polycarbonate panel thickness for secure windows? Answered

I need to glaze 16 small panes (430 x 275 mm) in very strong, cast aluminium window frames (8 per frame, either side of the door). Is 3 mm frosted polycarbonate going to be impact resistant enough to keep people out? The building these windows are part of is in a fairly remote place, so security is a concern but for cost and aesthetic reasons we don't want to glaze with glass and install a metal security screen. The current ugly solution is boarding them up and securing with screws but this doesn't allow us light inside. Cost is a consideration since I've been given permission by the company that owns the land to reglaze them and if I provide the labour they will supply the materials. 16 off 3 mm sheets, £3.85 each = £61.60 16 off 4 mm sheets, £5.14 each = £82.24 16 off 6 mm sheets, £7.70 each = £123.20 I've found lots of sites shouting "yeah polycarb is badass! It's unbreakable!" but not one that gives an idea for thinner sheets. Am I wasting money by going for thicker sheets? Or if someone's trying to get in might a 3 mm sheet be breakable?

No matter what I do they seem to get past the cameras. Trying to involve the local sheriffs office is futal. I live alone and work downtown so they know when my home is available. If it is possible to freeze the pictures, or move them around and delete without gaining physical contact with the camera then I need someone that is well versed on this to help me and tell me what to do to block it. Ihave set audios and before they enter I hear what sounds like someone fliping a wall light switch on and off.  Also,is there a transmitter of some sort that is wireless that blinks red or white. At first I thought I was just seeing things but I have pictures and witnesses now, so I am relieved...I'm not going crazy.  Yet. I also have a security system, they finaly learned to bypass it too. Can a block of some sort be put on my security system? Can anyone out there help me? My security man tells me that his system cannot be bypassed,  but refuses to look at the audios and vidios that prove it. What can I do to help myself and I am definately tech dumb, so please be kind and simple. Thank you.

Something to block office lighting?

The office building where I work has a conference room that has 4 fluorescent light units, each measuring 28” by 44”.  The problem is, one of the four light units is an emergency unit, and is always turned on.  So when we want to show power point presentations, etc.  the room is never  fully dark.  With the 3 lights being off, it’s just barely dark enough, and it would be so much better not to have the light from the emergency unit.  Due to safety codes, turning off this light is not a realistic option for us.  So I was examining it today and was wondering if someone had an idea to construct some sort of temporary “cover” that we can quickly and securely place over this one light unit while we have our power point presentations?  The cover would have to be lightweight, secure (we would not want it to fall on any clients!), and I think made of some sort of fireproof material, in case someone forgets it’s up there and the heat from the florescent light tubes doesn’t cause any danger of fire.  Each light unit has this metal “grid” that I guess is meant to reflect and disperse the light in an efficient way.  This “grid” is made up of smooth 1/8” metal strips, which create 24 empty space “cells”. The inside of the cells measures 7”X5.5” and is 2.75” deep.  There is a small clearance between this metal grid and the fluorescent tube lights.  And the light unit is 10 feet off the ground. Any suggestions??  Thanks!

LCD TV Display or Monitor for Security Camera

Another tech guy at my school and I were thinking of buying this camera for the auditorium. The light/sound booth is off in a back corner, and due to a not-quite-big-enough window, it is almost impossible to see any activity on the stage when it's dark. This is an issue for when, say, we are supposed to turn on lights as soon as someone's onstage. We already have plenty of hiding places for it in the ceiling, and it had an array of IR LEDs, to further help it see the stage.The problem is a monitor. It has composite RCA output, and we need to find something that will display it. It doesn't need to be big, as the booth is just barely big enough to fit three or four people in. However, we would like to find an LCD, because we don't have much room for a CRT. Also, if you haven't guessed already, it has to be pretty cheap. I think I saw a display a while back that was a 10.4" LCD with RCA input and no tuner for under $30, but I can't remember what it was called or used for, much less where I saw it. Does anyone have any ideas where I could find an LCD display? Spambots need not apply...

What kind of switch to operate and bypass motion sensor security light?

I would like to be able to manually operate the light for when I need it to stay on continuously, and then have it operate on the motion sensor when I am away from it. Basically I have a motion sensor light mounted above the entrance to my shed/ workshop, and sometimes I need to set up my sawhorses outside of the shop to do work at night and the light is sufficient, but when I have been still too long, perhaps doing some figuring or whatever, it goes out. I don't want to have to continue to wave my hands about to get it to come on every time it goes off. Do I need a double pole single throw switch, or a single pole double throw, or what(is a three way light switch a SPDT- [single pole double throw] switch)? Is there a way to wire it to a single switch where I could flip it over to one side to operate continuously, and then flip the switch to make the light work off of the motion sensor when I have gone in for the night? Please forgive the ignorance. I just can't envision it in my head. Thanks.

Looking for a 12V solution to prevent another 12V circuit to power on -- Reverse relay

Hello, I have 2 separate 12 volt lighting systems in the yard.  One is a low-voltage garden lighting that illuminates paths, trees, and a hot tub shelter. The other is a security lighting system, a 12V system that lights 6 each 900 lumen flood lights powered by solar panels and batteries. Other than shine a flood light from the landscape light system at the security system light sensor, is there a relay I can install that prevents the security lights from powering on until the landscape lights turn off?  I guess I am thinking of the redneck version of the relay that puts generators into play when the power goes out.

Light Socket Extension help

Can you help me find a safe way to build a cheaper version of this:   Here's my situation: I want to convert double-lamped can lights into adjustable spotlights without making any permanent changes other than unscrewing a lightbulb and replacing it with something else.  It needs to be able to go back to a lightbulb very easily.  The cans stick out from the wall and each socket is oriented vertically, so one points up and one points down, effectively washing the wall up and down with light.  The wall of 8 or so are wired so the tops are all on one circuit and the bottoms are all on another circuit. The item from Lowe's works OK, but is $17 and more flexible than I need.  Here's what I started to put together:   At the top is a 100W Par38 spot light, screwed into a single outdoor metal lampholder.  That is attached to a 1/2" pipe (PVC or metal), about 12" long.  Now, at the bottom of the pipe, it needs to screw in to the socket to get power.  I either need to get an E27 lamp base onto that pipe, or use a two-blade outlet adapter that screws in, and get a two-blade plug that is rigidly fixed to the pipe.   Is there anyway to do this that the NEC would smile at?  Absent of that, a way that is still safe and secure, and safely removeable without changing the existing light socket arrangement?

remote controlled light - revisited

Hello, Instructibles gang…. I originally posted a similar question over the weekend, and then got some feedback telling me that there wasn’t enough information to bring in worthwhile responses. My intention wasn’t to be secretive.  Rather, it’s a project that’s still in the planning stage and there aren’t yet many specifics. But I think I can still flesh it out a little bit, and hopefully gather some more specific suggestions. I’m planning a sort of a scavenger hunt thing coming up in October. Most of the stops/stations will be fairly straightforward “orienteering”-type scenarios: “20 paces at 250 degrees,” “north to the hollow stump,” that sort of thing. But I still want to mix it up a little bit. One of the ideas that’s swimming around in my noodle is that, at one stop, folks will be told to “push the button.” It will be dark, so they’ll have to hunt for the “button”… basically a doorbell… and maybe secured to a tree (in such a way as not to harm the tree). When they press the button, a light will be illuminated at a short distance, leading them to their next stop. I know that I could easily do a simple circuit with actual wire, but it would be far nicer to achieve the same result wirelessly… and even though I’m not very electronics-savvy, I imagine it would also reduce the problem of resistance in the circuit. This only needs to operate over a relatively short distance… almost certainly less than 100 feet… probably much less. And while it must be able to operate out of doors (a woodland trail in a rural/suburban park) it only needs to last for a few hours. An LED… or maybe a chirping sound effect… something that would draw seekers from one spot to another. Thanks for any suggestions. And please let me know if more information is needed.

Safety of your garage door or car remote...

No time and no pics for a proper Instructable, so I just put out some word of warning ;) Around here bad people take advantage of the fact that a lot of new houses have the garage right next to the house. With these you usually also get a door so when you park your car you don't have to get out of the garage again. All controlled by the press of a button on the remote... Some fancy guys got a device working similar to the IM-ME Open Sesame hack a few years back. But unlike the original author the new guys found ways to make money by providing working "universal garage door openers" on dubious websites. Problem with the new model is that it not only fakes a remote with dip switches but also the newer models with so called "rolling code", "intellicode", "changing code" and so on. The old remotes with dip switches should actually by phased out years ago by any owner who values his stuff... But the new models are still deemed secure and next to impossible to hack - well if you trust the advertisement... How does the code hacking work? The old dip switch models allow for a maximum of just over 4000 different codes and come in just 3 or 4 frequency bands. No real problem for anyone with basic electronic and coding skills to hack these - as shown with Open Sesame. The new models all use a so called rolling code, here the remote and opener are paired through 32 bit of ID code and an encrypted part that changes every time. Both remote and opener calculate the next code once a button was pressed or a code received. To overcome reception problems the base usually calculates the next 256 codes in advance - and that is the entry point for bad boys. The illegal device scrambles the frequency detected while storing the code received by the orignal remote. As the door did not open the owner will try to press the button again. Still scrambled to opener does nothing - until the device sends out the first recorded code! Now the owner can drive in and is happy. Of course he still needs to close the garage - again all is scrambled and the code stored as before. You see where this is going.... It is even possible to set the amount of required tries to capture, so in theory a bad guy could get the next 10 or codes in advance for use once the owner is gone out... Worst thing however is that these illegal devices not only open garage doors but also cars as a lot of them use similar systems for their remotes - up to the point of starting the car with it. Took me only 2 hours with Google translate to find a website outside the usual search results that offers these "gadgets", along with WiFi and cell phone jammers, credit card copy devices and more things I don't want know about... What can you do to protect yourself? First check what type of remote your system uses - if there are DIP Switches than replace the remote system or the entire device in favour for something more secure. If you already have a rolling code model that you are far better off but sadly no longer totally safe here. A lost remote should not only be replaced but the old one removed from the system as well - you never know if you just lost it or someone took your remote ;) Alternatives exist, especially if you are not afraid of doing some open heart surgery on the electronics of a garage door opener. You can add a WiFi module and use your mobile phone to open the garage - search Google if you like the idea ;) Another very neat way is using a second transmitter that keeps the relay for activating the opener from working. This can be anything from a BT module paired with your phone or cars BT system over a keycard to numberplate recognition cams. A good system also allows for a "holiday mode" or similar. Here you can set this mode with one remote until you deactivate it with the same remote the system will not react to anything. Great if you leave the house for more than a day or two... As a last resort you can always get a big and angry dog to sleep in your garage.... What if you are renting or a bit limited with the electronics and soldering skills? Not all is lost if you can accept a second remote for added safety. These days you can get plug in converters for your mains voltage outlets that work with a remote control. Unless they use Infra Red for this they are great to disable your opener. Simply plug it in where the power cord for the opener is and then plug the cord into it as well ;) Now you can fully shut off the opener with the press of a button and only if the power outlet is switched on the opener will work. If in doubt you can use a double outlet adapter an extension cord and a night light to indicate wether or not the opener has power. Ok, and what about the door lading from the garage into the house? Well, of course keep it locked and if you are home also keep it locked. At least this way you have some extra time in case someone tries to enter through your garage while you are sleeping ;)

Would this require Programming?

Hi! I'm building a laptop bag alarm for a project I'm working on, and I'm pretty new to electronics. Would anyone know how I could make a system where a switch would be flipped to turn 'the alarm' on or off, and when that switch is flipped, the system would do nothing when the security system is triggered. The security system being 3-8 LDR sensors inside the bag, that will trigger some sort of logical part, that would be able to make the decision whether or not to sound the alarm, based on the status of the switch (flipped or normal)  I'm a programmer, so the system looks like this to me:  IF ALARM_SWITCH_ON && LDR_TRIGGERED { TRIGGER LIGHT && SOUND }  IF ALARM_SWITCH_OFF && LDR_TRIGGERED { DO NOTHING }  ELSE { DO NOTHING } Anyone know how this could be made with circuitry? or whether it would require programming? If it required all circuitry, is there anywhere I could get help with drawing up a circuit diagram?  Cheers & Thanks!  Karan

Diy LED strip light powered from a solar powered battery bank (for painting/drawing at night)

I like to paint nightscapes and so far headlamps are not working so well for me. I used a portable light bar one night that worked well (on loan) but it was too heavy. I've been through stores looking for the right thing...and harbor freight came close. But I need something lighter weight and less expensive.  Two or three led lights don't cast enough light and 30 led storebought lights are too much light. I have a solar powered phone charger with battery bank (with usb connections) that I now plan to use as the portable power source. I plan to use a pringles potato chip tube as the light housing that can be attached by clips to my pochade (really a mod'd cigar box) on top of a camera tripod. I guess my main concern is weight on the box, so I thought running a cable off a power source hanging from the tripod would be more secure and less likely to fall in my palette (as has already happened). I need help figuring out the circuit board; and also choosing the right white led for color purposes. Any thoughts?

Human Detector

I'm trying to come up with a small, cheap, simple circuit that will detect a human. I plan to use a grid of luxeon rebel OLEDs and whatever detector I come up with embedded in my ceiling to light up only when you are under them. I've looked into passive infrared, but it's fairly expensive for the components I could find. Any leads for circuits, ideas, or parts? I'd use parts from cheap security lights, but they tend to be around $10 each and I would probably need around12-18 ... kinda painful on the pocketbook. Thanks in advance for any help!

Motion Detector Trail Camera

Motion Detector Trail Camera motion, detector, detection, surveillance, security, trail, camera, webcam, webcamera, wildlife, IR, arduino, cheap, inexpensive, spy, cam Hello everyone. I'm planning on building a motion detector triggered "trail" camera, as inexpensively as possible.  I want to use a cheap IC (integrated circuit), if possible, not a $45 Arduino.  I've learned that the most expensive component of this project seems like it will in all likelihood be the digital camera module (the lens and CCD, which is a pixelated digital sensor for the brightness and color of light).  However, I have an old webcam from which I could salvage the camera module out of, if reasonably convenient.  And this is the primary thing I think I'll need help with. Beyond that, my plan is to get a cheap IC, plug the camera module into it on a breadboard, find (hopefully find and not have to delve into learning how to program this) some programming code for the IC to capture the image data and turn into some kind of conventional image file, and then capture the digital camera files on an SD card via SD card shield plugged into the IC via the breadboard.  After the initial project is finished, I'm thinking of taking it a step further by transferring the image files directly to a computer, and upload them immediately to the web but that will come later. And of course write some code to signal the camera to shoot when the motion detector detects motion.  And do some research about which kind of motion detector I want and get it.  But this part seems relatively pretty easy.  Oh, and also get some kind of battery; probably a Li-Ion cellphone type battery with a shield or 'holder' for it.  Haven't yet researched about the shield / 'holder' part for that, but seems like it should be easy. Questions: 1) What kind of programming would I need for the IC to capture the image data from camera and turn it into conventional image file?  Where would I get it?  ...or what?  I just want pictures, not video. 2) How do I salvage the 'camera module' from a web camera for this?  Or rather, perhaps I should ask, once I salvage it, how exactly do I plug it into the IC to send the image data to the IC...? 3) What is a cheap but effective IC for this? Anyways, thank you; cheers. Jack Oh, also wanted to note that I indeed have been looking through many tutorials about this stuff.  I guess I'm at that point where I feel like it would be worth it to write down where I'm at and ask for further directions.  Lol.  Thanks again.

Interference of codes problem

I want to ask for some help from you regarding of my final year project. I'm doing a simple SMART HOME project by using Arduino wemos. While compiling the function of the smart home, i've encountered some problem to compile it. Actually this is my first time using arduino and i don't really understand about the arduino ide syntax. Actually, there is no error in my coding. Basically, there are 5 functions that I want to put in that smart home. First, to control the lights,curtains and fans using ON/OFF Button, and security system only by using TSOP and IR, and lastly controlling the roof for the clothesline. So, I've problem with controlling the roof for the clothesline. The roof for the clothesline works when the rain sensor detects water/rain and it actually functioning when I do it separately. But, when I compile the code with the other functions, the roof is actually functioned, but it works only if I switch ON/OFF the lights/fans/curtains. So, here I attached the source code of my project with four functions, which are for the lights, fans, curtains and roof.

Mounting an LCD Monitor

Hello everyone! I am working on project that involves mounting a 19in LCD monitor onto a board. The monitor has 4 threaded holes in the back for mounting onto an arm or wall mount. I was wondering if anyone knows what kind of screws to use or has any advice on properly and securely mounting the monitor. The monitor is a Westinghouse 19" LCD. The whole project is going to be a small entertainment center for my monitor. I am going to attach speakers and accent lighting. I am doing this for a class project and drafting it in Vectorworks. *If anyone is interested in looking at the plans I will send them to you; however please don't redistribute them. They will be in DWG format. GC

Solar powered RGB led strip

I want to make a solar powered rgb led strip. My thought is something like christmas light. I would like the lights to have effects like fading, blinking, and chasing. What equipment do I need and what steps do I have to take? I was recommended to use arduino and have started looking at that and would like to use that as it seems easy to use. The led would be RGB led so that I can change colors and stuff like that. I was thinking of having 2-3 independent "lines" which would make up one strip. For example, one line would be red and the other would look green. it would look like this: r-g-r-g-r-g-r-g with r meaning read and g meaning green. I dont know if it would be best to run each line in serial or parallel. Then I would like to provide power for the whole strip with a small solar panel. Sort of like the ones used on solar lawn decorations or solar motion sensing security light. Hopefully I wont need a big solar panel and a small one would be enough to power all the leds that I want. I'm thinking of having about 100 led per strip so 50 led per line. After this is done I might want to do a strip of 200 led. And finally, I would like for the light to turn on and off automatically at dawn and dusk.  Is anyone willing to help me out with this project? I am a newbie and need lots of help.

DIY Outdoor Event Searchlight

In am interested in building an outdoor event searchlight or advertising spotlight that you might find at the opening of a Hollywood premier. Basically, an intense beam of light projecting miles into the sky to attract people to a location.  I searched Instructables and found some projects for stage spotlights but nothing like an outdoor searchlight. I did locate some complicated Carbon Arc and Xenon lamp projects but these involved a lot of expertise in electrical engineering! I am a novice but I am comfortable with basic "household' wiring. With that said, my thought was to try using 7 or 8 (maybe more) 55w car Xenon HID (6000k range) headlights as my light source. Xenon HID produce three times the light output as standard halogen headlamps (3000 lumens vs 1000 lumens) and require less energy. The "conversion kits" come with the igniter module and inverter ( ballasts) which reduces the amount of electrical wiring. At this point, the power source could be to use 110v household AC current and then, using a AC to DC converter, turn it into DC voltage and let the "conversion kit" components change it back to AC.  From what little I know, Xenon HID take about 25,000 volts to start a Xenon bulb and then 80-90 volts to keep it operating. During operation the AC ballast frequency is usually in the 250 to 450 Hz range. Each bulb draws around 6.5 amps at startup and then stabilizes at around 3.8 amps. Next, I would place the bulbs into the center of a Ellipsoidal Reflector to direct the light skyward. Basically, the 7-8 Xenon HID bulbs would be secured to a piece of sheet metal and then surrounded by a reflector so it would be like a VERY large headlight pointing into the sky. In one of the YouTube videos, the guy used a trashcan as the housing. I am not looking for something this large but similar in concept.  I located an Ellipsoidal Reflector on Ebay for about $55 and then I might just build a housing around it.  But would the reflector be enough to concentrate the light into a strong beam? Or, would I need to have some sort of lens to focus the light? If anybody has constructed something similar of if you have any pointers on what to do, please let me know.

Physical Space Installation Game

Looking for people who are interested in helping out on the electrical engineering side and/or set design of a installation game. Various people in the industry (theme parks and video games) should stop by during the exhibition and credit will be provided. On the electrical side it would be helping out with networking of Arduino boards to run each "gag" and be linked into a show control. On the set design side - help with the set design of the piece, lighting, and construction. The installation will take 3 players and have them "break into" a vault with various high tech security (lasers, pressure sensors, computers needing to be hacked, etc). Other examples of this type of work would be "The Tomb" and "Operation Spy" by 5wits, La Fuga by Negone (in Spain), interactive haunted houses, and theme park attractions. Message me if you have any questions. Thanks!

Protesters in China Use LED Throwies

Pro-Tibet protesters in China used LED Throwies to illuminate a large "Free Tibet" banner in China's Olympic Park, right in front of Beijing's National Stadium.On Monday, five pro-Tibet activists unfurled a banner spelling out 'Free Tibet' in English and Chinese in blue LED 'throwie' lights in Beijing's Olympic Park tonight. The five were detained by security personnel after displaying the banner for about 20 seconds at 11:48 pm August 19th. Their whereabouts are unknown. As far as we know, James Powderly, the author of the LED Throwies Instructable is still in Chinese detainment after being picked up by Chinese authorities a few days ago for planning a LASER stenciling event.Throwies are the most viewed Instructable in history, with over half a million project views to date.Article on LED Throwies in Beijing

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)

Seen anything interesting in traffic lately?I recently sat along our town's main cruising street and counted how many motorcycles went by. 15 in an hour. That's up from when gas was cheaper! We'll see about when winter gets here, though.One of my professors has a Triumph 900, the classic-looking one. He wants to get rid of it. He wants to trade for a Harley. I don't have a Harley. It's still his.One of the security guards nearly took his own head off on his sportbike of unknown bloodline by coming screaming around a corner and almost clipping the No Parking sign.On my way home, a very nicely done cafe racer that looked like a modern-parts Vincent passed me on the highway.On the way across town, we were at a light next to a long, low, and loud chopper, with an ultradetailed paintjob.A few months ago, we were at a light when a '24 Harley went by on the cross street.I have a bike that can move under it's own power, which you have all seen if you've read about my custom seat at Road KingsFive scooters, two of which were of the sewing-machine, park-on-the-sidewalk-and-piss-us-all-off sortTwo Victorys"And a partridge in a pear tree"

Replacing an old bathroom fan

This is an idea someone may be able to use, but it does not quite rise to what I would want to do as an Instructable. A widow friend has two bathrooms, each with a very dated bathroom fan in need of replacement. I was able to mount the works (fan motor, fan blade, and mounting plate) for the new fan onto the old mounting plate after modifying the old plate. This saved me hours of work in a very hot confined attic when time and tools available to me were quite limited. Had I torn out the carcass for the old fan and tried to put the new fan carcass in its place, I would have needed to fashion a wooden framework for mounting the carcass that would fit just right between the ceiling joists, all so the fan would be properly centered above the existing hole in the ceiling.  The mounting plate for the new works was just a bit smaller than that for the old works. The height and diameter of the new fan cage were very close to the dimensions of the old fan cage. I began by using a cutting wheel on an angle head grinder to cut through the old mounting plate around the circumference of the old fan cage. Then I positioned the old mounting plate over the new works and its mounting plate. The glass dish that would cover the light bulbs fastens to a shaft that screws onto a threaded stud centered between the corners of the new mounting plate. I sighted across the corners of the mounting plates so the threaded stud was centered. I clamped the two mounting plates together and drilled four holes for 10-32 screws 1/2 inch long and secured them with nuts and lockwashers. (I did need to cut out part of the new mounting plate so the fitting for the two electrical outlets [fan and light] were accessible to plug in both the light and fan cords.) Had the glass dish mounted to the works differently, I would have used measurements from at least two sides to the center of the fan's shaft to position the new mounting plate on the old. Once the two mounting plates were held together with four screws it was a simple matter to put the works into the old carcass and plug in both the fan and the light to their respective receptacles. There was no question the works would fit because they were attached to the old mounting plate that had been taken from the old carcass. The round opening in the ceiling drywall bordered on being too large to be covered by the escutcheon for the new cover/light fixture. I added some drywall spackling around the edges to close any imperfections and gaps. For me this was an idea that worked and saved me a lot of time.

How to identify breaker for a currently dead circuit? Answered

There is a circuit in my house which has become unpowered, but I can't find a breaker for it.  None of the breakers in the service panel are tripped (yes, I know what that looks like), and the two labelled "not in use" don't affect this unpowered line (I've cycled them both a couple of times).  The circuit has two GFCI outlets on it; both are unpowered and the TEST buttons have no effect (I've tried RESET, of course).  The circuit also has an overhead fluorescent panel, and an outside security light, neither of which are working. I thought I could use a circuit tracer (a.k.a. breaker finder) for this, but what I've read so far indicates that they only work on active lines (i.e., so you know which breaker to turn off). Does anyone have a non-obvious suggestion for how I can find where this circuit is turned off?  Or could I use a circuit tracer for this, even though it's unpowered?
