Seeing Double

Well hello! Just noticed a slight bug that y'all at HQ should know about. When I get a private message from HQ, such as the Halloween Postcard message, and the "Being Featured" message, I receive them twice.  Usually the doubles are quite some distance apart.  I received one double a day after the first one, and the Halloween Postcard message sent its double ten days apart (fearing that I needed to sign up again, I did just in case). Thanks a bunch!

Double comments?

Double comments? I have been noticing this a few times within the last few weeks. Such as today. I got a comment from DJ Radio someone and then about 40 minutes later, I got the exact same comment. I'm pretty sure people are not doing this as a joke. When I'm talking about this, I'm talking about the comment tracker, it doesnt appear twice on the actual ible it is on. Has anyone else seen this happening?

Experiment : Double Slit

Hi !I tried to reproduce the Double-Slit experiment with a cheap red laser-diode (<1mW).Below are various results obtained from some variations of the experiment ... (with a double slit, with a pinhole, with a thin wire, and with a hair (and also with a single slit who gave almost the same result than with a hair))I also tried to reproduce it with an other source of light (and got electrocuted). But so far, I'm not satisfied by the results I obtained with the light bulb, and I failed with the sun.Do you have some experience to share about this experiment ?Do you have successfully reproduced it with an other source of light than a cheap laser diode ?

Stairs that double as dressers

Here are some plans for modifying your stairs so that each step can also hold a drawer for extra storage of all your stuff. The things you put inside would have to be of the occasional-to-rare use since these look like a pain to have to deal with on a regular basis. Other concerns are just how well the heat will be kept above or below and if they can be spring loaded so you don't step into an open drawer on the way down the stairs and brain yourself on the landing. Oh yeah, the risers that get removed are often providing structural support for the step above so be aware of that as well.But if you can pull it off safely, it's a neat trick. link

Ideas for a double click switch?

I'm looking for a way to make my car boot open remotely, when my remote only has a lock and open button. I was thinking of making the servo activate when the unlock button is pressed twice in succession Each press sends a 10V-14V current to the solenoids in the car doors, so I've tapped into that I tried using a rc circuit, but it's way too unreliable, even when I have a voltage regulator at the input Does anyone have any other ideas? Something using the 555 ic maybe?  [EDIT] I have an idea; detecting if a door is unlocked or not, and it if is, then hitting the unlock button would open the boot *BUT* I need to find a way of making a delay; so when a signal is sent, there is a brief delay before it reaches a relay

12v double flash with Arduino?

Hi, I am in the middle of trying to figure out how to get my Arduino to power a 12V LED on a double flash for use in a model (USS Enterprise NCC 1701). The trouble I have is the double flash only has a delay of 0.7 secs so I think if I used a relay it would not be quick enough to turn on/off? The LED powers OK and runs from the Arduino on it's normal 5V, however it is not bright enough (I am going to hook them upto fibre optic so need the extra brightness). Any ideas how I can do this, presumably putting 12V into the USB connector would fry my Arduino? I have never programmed or used an Arduino before, nor have I done much in the way of electronics for 25yrs, so I am a little rusty, any help would be appreciated. To give you an idea of the speed I require, this is some of the program (within a loop). digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)     delay(70);              // wait for 0.07 second digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW     delay(70);              // wait for 0.07 second digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)     delay(70);              // wait for 0.07 second  digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW     delay(3000)         // loop after

Knex double shot prototype

Here we have a slightly angled pin knex gun. The pin is slightly angled down, making the pin come in the magazine well angled, hitting two bullets instead of one. It uses an internal flexy bullet pusher instead of the external ones. It shoots two bullets 30 feet using two bands. It has a yellow rod magazine that isn't removable. It also uses a unique trigger system. Its comfortable, light weight and is very fun to use. No sights, its just a prototype.

These stairs provide access to a loft room in a tiny apartment as well as a nifty spot to place loads of old paperbacks and CDs. As someone who is getting threats to start getting rid of books on a near daily basis, I can appreciate this.Another thing that's interesting is that this is the first set of stairs I've seen that has a prescribed way of going up and down them. You're meant to step on the side that sticks out more with the indent allowing the traveling foot to clear it.

Double-Opposite Coil Speaker Design?

So I finished a new speaker I designed, today. It was just then that I thought about the possibility of creating a new design. In the tradition speaker, a coil sits below the magnets, and they are pulled in and out of the coil, creating vibrations (subwoofer).I like this method, and all, but I wanted a bit more! So I got to brainstorming. If you were to put a coil around the magnets, it would still work - it's just have no bass what-so-ever. Well, what if we were to put a coil on the bottom, as usual, but add a second coil on the opposite side, while allowing it to encircle the magnets, but not get in the way. So when the magnets get pulled into the coil, the second coil does not interfere, but still is close enough to the magnets as to create sound. Would this have any adverse effects? Would it ever work? I've included an image so you can see my vision. I may very well just be stupid, but hey, it's an idea. Going to work on it tonight.

How to make a double electric circuit?

First things first, I don't think the title is accurate for this question but anyways, We have frequent power cuts in the place where i live and this is pretty irritating as my modem wont work and i cant use the internet. So I have this backup generator and I got an extension from that to power my modem (The backup generator only powers specific lights). But, the problem i face is that every time the electricity goes, i have to manually remove the plug from the mains and plug it into the generator and vice versa when the electricity returns.  So, in a nutshell, i want to make a device which can accept both the mains and generator inputs but output only one of them at any time to the modem. Problems: If the generator switched on as soon as the mains went, it would be fine. But thats not the case. 1) As soon as the power goes, the generator takes about 2 minutes to switch on and then my modem takes about 3 minutes to reboot. 2) When the power returns, the generator stays on for about 2 minutes as well. So if I were to make the device I mentioned earlier, For 5 minutes I would have no internet (generator+modem starting times) and for 2 minutes I would get 440 volts instead of 220 which would practically kill my modem. Finally the device should have, (I think) 2 inputs. 1 output. A small battery or a capacitor(For the 2 min generator lag) A switch to automatically switch form generator to mains. So can anybody give me some ideas? If you didn't understand what i am trying to say, i can gladly rephrase. I thought of using a ups or something like that but i don't know how to provide two inputs and not kill the ups itself. Thanks!!
