1 in a million shots!

So one time, i was practising throwing cards. i lay on the floor tossing cards at the ceiling. One stuck there, embedded in the popcorn texture. Stayed there for weeks. High ceiling.   Any other examples of a  long shot?

Photo orientation bug ?

Hello, I know that this sounds unlikely but if I re-orientate a photograph in Preview on my Mac and then put it in an Instructable, it reverts to the original orientation. This has only been the case on my current Instructable. Has anyone else found this to be so ? Also I still cannot reply to comments left on my current Instructable. Thank you.

I Found A Cure To Hiccups

I just had the hiccups ten minutes ago and used this cure, it works for once!(unlike most cures ;-) ) Take a deep breath into your lower lungs and hold it there, not in your mouth. Then, still holding your breath, clench all your stomach muscles and hold for a few seconds. Finlly, let out your breath, and your hiccups are gone! Do you have good cures?

Leaking PVC Soil Pipe

The PVC soil pipe under our bathroom has developed a slow leak. This pipe is inaccessible as it runs under a platform that lifts the bathroom above the concrete floor of our enclosed garage. It may be a crack in the pipe (unlikely) or a connection between the tub and the main pipe (more likely). Is there a liquid sealant that I can pour into the tub drain that will seal this obviously small opening?

Knex ammunition

Nearly all Knex guns fire rods or connectors that are only 1 wide and 1 height  the length varies, but why not fire rods which are 4 pieces taped together so they have more force behind them and you can tell if you've been hit unlike some single rod guns where they have great range but little force. Would anyone make a gun like this ?

Lipo battery cut off

I'm using a couple of Lipo batteries to power a speaker on a trailer, I bought 2 low voltage alarms that plug into the balance cables but upon testing I found it to be unlikely that I'll hear them over the speaker. So would it be possible to modify the alarms so that they activate some kind of cut off device attached to the power cable instead? Each battery is 4s 10000mah.

Independent suspensions? Answered

I have been trying to figure out how to put an independent suspension on a Huge scale RC.  What I have noticed on large cars is that unlike small RC cars the rod going from the dif to the wheels is solid and can't extend/shrink.  Why doesn't this bind up? I have also noticed that for some reason they don't line the suspension up to move exactly up and down. The wheel's pitch is actually set up to change as the suspension depresses.

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 that...off, 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

Dilithium created and observed in the laboratory!

According to a news report in Physics Today, scientists at Lawrence Berkeley National Laboratory have confirmed the creation of element 114 first reported by Dubna physicists in 1999. As true afficionados may recall from the original Star Fleet Technical Manual (pictured), element 114 is dilithium, used to regulate the matter-antimatter reaction for warp propulsion. Unfortunately, with a lifetime of just a few hundred milliseconds, it's unlikely that crystals of element 114 will be produced any time soon.

Science and Spirituality -- not necessarily in opposition

There's a cute little article (blog entry) in New Scientist, about a collaboration between a Buddhist monastery in India and San Francisco's Exploratorium. Buddhism, especially under the 14th Panchen Dalai Lama, has had a very favorable and welcoming attitude toward science. Traditional Buddhist practice toward enlightment stresses observation, experiment, and reproducibility (all classic hallmarks of "scientific" investigation), and elevates personal questioning above outside authority (unlike traditional Judeo-Christian-Islamist "revelation").

How do I add power to K'nex motors?

I'm working on a K'nex automatic machine gun. Unlike most K'nex mg's, this one fires from a hopper and does not have a barrel for every round. Unfortunately, it doesn't work because the motor can't pull back the rubber band. I have one of those clear motors with a red battery pack.

Freescale Programming?

Out of the many samples I recieved last week, the freescale MC908JL8MPE is one of the few that I like the look of. Its a beefy PDIP with 28 pins, unlike the many TQFNs I've recieved I could actually solder this (well no need as it fits in a breadboard). But my problem is, there doesn't seem to be many easy-to-follow tutorials for programming these microcontrollers. The only simple solution seems to be to buy £100 programmers.. which I'm not too keen on. Is there a simple way to program them via parallel/serial or maybe using my usbtiny to program an atmel chip to program the freescale chip? Thanks.

What to do with an electric toothbrush?

I now have a headless electric toothbrush and wondered what make with it since it seems too nice to just throw away. Unlike most electric toothbrushes, this one doesn't rotate back and forth but instead reciprocates forwards and backwards about 2-3mm. Anyone think of something useful I could make of it? I tried to use it as a metal etcher, but it doesn't move fast enough for that unfortunately.

food for teeth ?

Hello. I've heard that teeth were able to absorb some substances/molecules thanks to the porosity of the enamel. Unlike bones, as they are not self-regenerating from the outside, I was wondering what substances may be usefull to offset the erosion of the enamel (remineralization ?). Is there something that could be concidered as a "food" for teeth ? Also, about dental caries, as they are mainly caused by bacteria eating "fermentable carbohydrates" who generate acidity, here is a question that may sound stupid, but that is serious : - to make the work of those bacteria harder, is it better to sleep with the mouth wide opened (oxygened mouth) or with the mouth closed (anaerobic conditions) ?

How can I make a dry ice blasting machine?

I have seen commercial machines that use compressed air to shoot a stream of dry ice (CO2) pellets or shavings at a dirty, oily machine to clean its surfaces. Unlike sandblasting, the CO2 sublimates (goes from solid to gas without passing through 'liquid') and leaves no residue other than the crud it blasted off. It can even be used on machines or electrical panels that are powered up! But these machines cost multiple $1000s. Anyone have a plan or experience with a DIY version? Thanks.

I posted a very similar topic a couple minutes ago but I'm pretty sure noone can see it, so I'm copying and pasting the body. I just want to check this before I blow up my mosfet (I've never used mosfets before) Is it correct that you don't have a resistor from the voltage source to the gate (unlike bipolar transistors) Should or shouldn't you have a 1M ohm from gate to ground? Let's say I'm driving a mosfet from a 555, should I have a resistor from the output pin to gate? I think the schematic I'm reading just through a mosfet in where a bipolar use to be without changing that resistor.

I recently created several Instructables from some of my youtube tutorials, and was surprised to find that they didn't hit the "recent" list.  After some investigation I noticed that nearly all of them had a publish date of several days earlier than I actually published them which is causing them to show up so far down the recent list that they are unlikely to ever be seen.  Seems like they are all two days early.  Everyone of my published instructables listed as Nov 19, 2014 was actually published today Nov 21, 2014.  Infact the 19th even pre-dates the creation of some of the video content.

It is silver, no rust and it will not be scratched by anything. It is magnetic, it's about as round as a quarter, and maybe an inch thick. It weighs 150 grams, or 5.37 oz. It randomly appeared on my back porch one day. The top looks like a bundt cake design, the bottom is flat with a perfect circle in the middle. I found it in Southern Missouri. I have asked multiple people and no one has any clue as to what this could be. I would say its a meteorite, but the shape of it is unlike any meteorite I've ever seen.  Any referrals or thoughts about what this could be would be gratefully appreciated!!!

Contest ideas

I want to make the Create a navigational robot. It can already navigate pretty well, but it is not very intelligent. I want to add Sharp GP2D120 IR sensors so that the robot can recognize an obstacle before it bumps into it. Then it will turn and look for a clearance before it will move ahead. This means it is very unlikely to get stuck. Currently I'm working on a CMUcam, so that when integrated onto the Create, it can follow a white line around, and might come in handy for other purposes as well. I am also toying with the idea of using GPS navigation as I have the receiver and antenna that was used for another project. If GPS is integrated, the Create will be able to move from one waypoint to the other while avoiding obstacles on its path.
