Depth of the thread cut by a tap?

If I was to drill a deeper hole, I buy a longer drill bit of the intended diameter.  I am sure the same thing apply to the taps as well.  However, in their specifications, I do not see anything about how deep a cut they would make.  So, my question is, what should I be looking if I need to make a deeper thread than than the tap I already have?  I mean is there a number which would say that this tap goes only one inch deep and so on? Thanks.

Which Direction Does She Spin?

Check out the optical illusion below. Since the figure is totally black, there's no depth- you can see her spinning either clockwise or counter-clockwise. Which way do you see it first? Try reversing the spin direction- moving your finger in a circular motion at the rate of rotation can help you reset. How easy is do you find it to swap perspective? Does it make your brain hurt?

Shallow depth of Field... From a tiny lens?

It is a nice effect to open up the aperture of a camera, focus on the subject, and allow the background to go blurry.  But many of today's still and video cameras have a tiny aperture. How can I get shallow depth of field from such a camera?

Pin-Pressions/ Rotation Sensor

I'm trying to build a sensitive pinpression device: one that can see 3d digital images. The device would be able to read, record and organize the depth of each pin. I think the first problem to overcome is figuring out a cheap way to measure pin depth. I think it will be best to do this with rotation sensors. Does anyone know how to build or where to buy cheap rotation sensors?

Electronic water level gauge for well

I have a 32m deep, 95cm diameter well, that is covered with two heavy concrete covers. The water depth is about 20m down from the surface. I cannot easily access the well to sound the depth or visually check the water level. I would like to build an electronic water level gauge that will tell me the amount of water in the well. I can then regulate watering accordingly. It was suggested to me that I use a washing machine pressure transducer but I have no idea of the circuit required. A refined solution would send data to my PC !!!! I have 240v AC supply to the well pump. Any ideas? Steve

A look at recent FireFox 3 vulnerabliities...Heads up

True to form, Billy Rios promised a more in depth look at the MSFA2008-35 vulnerability which is another protocol handler flaw in Firefox 3. As previously reported here, this was another protocol handler flaw that led to arbitrary remote command execution, and is especially dangerous since it can be deployed widely through the use of a cross-site scripting attack vector. Note, Firefox3 no longer registers the Gopher protocol handler, which is a great security decision.Site Link - ZDNet

These serve two purposes. First they look really cool. Second, they actually do improve the sharpness of vision at long distances at their smallest aperture. They do this by increasing the depth of field by limiting the aperture similar to a camera lens.'Don't you just love them?Check it out hereThe Titanium Photochromatic Variable-Aperture Spectacles.

But I need someplace that can cut up to 36"x36" sheets down to a depth of 1/16th - 1/8th of an inch.  Anyone know of a service that will do this?  I can provide material.

shelf brackets for angled wall

I have no doubt this is simple for someone who knows, but... I was to put shelves on a wall that is slanted out from the floor.  I see Ikea has a locking bracket for shelves but I want to put in bigger shelves than that bracket supports.  How do I make a bracket for this situation?  I am also open to other suggestions.  I want the top shelves to be deeper, say 24", and taper down to narrower depths so I can utilize most of the wall. Thank you for any assistance.

Looking for the smallest wide angle lens I can find

Premise: I have a droid incredible and I love taking pictures with its awesome 8MP camera.  I don't like its depth of field however.  I'm sitting here right now, looking at the camera enclosure, and I'm wondering if I might be able to pop open the red dome of the camera and slide in a tiny wide angle lens.  I've seen the cellphone wide angle lens kits you can buy for things like your iphone, and I actually did buy one for my Zi6.  Worked amazingly well, but even in that small form factor, it sticks out too far for me if i were to use this on my droid inc. Objective: I'm looking for an elegant solution that keeps the wide angle in the enclosure, and can't be knocked off or removed while in the pocket. How feasible would this be?  Would it be possible to find a small enough piece of glass that would give a wide angle view in such a small form factor?  I'm just guessing here, but I'd say the diameter would be 8mm and probably 2 or 3 mm in depth.  Thats pretty tiny... Anyway, I just wanted to get some suggestions from the DIY crowd.  I'll include some pictures of the camera's enclosure to take a look at. Thanks.

Hey all, I've been looking through this site a lot, and I have been intrigued by all of the amazing projects. However, I feel my knowledge of electronics is very lacking.

For example, something that will explain fairly in-depth how circuit boards, transistors, resistors, and all of those great things work. I appreciate any help I can get.

Knex Construction?

Hello everyone, I am thinking of building something from knex, but I do not have the slightest idea how. Basically I want a stand that will hold my DS, psp, two ds games, and three psp games. I think the psp and ds will just sort of dock/hang on the sides of the stand, the bottom of the stand will be risen as to reduce dust, and improve looks (aka legs), and the area for the five games will be divided to provide two different depths. Moreover, there needs to be a front piece to keep the games from falling out of the front. Perhaps a tilt to the back would be nice. Let me know what you think and any ideas you have. Thanks!

Ground Penetrating Radar

I am looking for any information regarding Ground Penetrating Radar (or GPR). I am a newbie to this type of tech and was hoping the someone may know of a basic reference manual or other sources that could contribute to building one from the ground up at reasonably little cost. Also, I am looking specifically for something in the high frequency range - good resolution at minimal depth. The hardware side is more important although any advice/resources on the software to interprete the data wouldn't hurt. Thanks in advance! By the way, my user name(just created and second guessed) has nothing to do with being dug on digg, or anything to do with digg for that matter - just thought it had a nice ring to it... Thanks!

Finding speaker specs based on case design

I know there are a handful of Thiel/Small calculators to build a box, but what I am looking for is a way to find which speaker specs would fit into a particular dimension of a design. What is that ONE thing that really determines the size of the casing. Is it Vas, Qts or something else. So for example, I want to build a small portable bluetooth stereo speaker with dimensions of length - 6inch, height-3inch, depth-2inch. So if I am looking at speaker datasheets(suppose full range), can I get a rough idea that I can use it in such a type of casing. Mind you there would be two of those speakers. And as a sidenote, what about if there are tweeters, woofers, etc.

Making/Modifying a USB Hub

I'm currently designing an accessory for my computer which will house 4 USB ports as a USB Hub.  The issue i've got is I need to be able to contain the whole USB Hub in an area that is only 22mm deep and 170mm wide.   I've taken a cheap USB Hub apart to see what it was like and I have run into a few issues. The main one is that the total depth of the PCB to the end of the USB Ports is 35mm, 13mm over the size I need.  The next issue is that I need room to place a screw between the USB Ports, 2 either side.  These screws have a width of 3mm and a head size of 5mm.    Putting a hole like that in the PCB would break and short the connections. Does anyone have any suggestions?

candle's black smoke deposit seems not to be electrically conductive

(This is the first topic of the "failed experiments" group.)I was wondering if the black smoke of the candles could be electrically conductive (carbon) when deposited as a layer over a piece of glass.After a quick and basic experimentation, it seems it is not.Here is how I proceeded :- I've put a piece of glass over the flame of a candle so a black smoke deposit appear on its surface.- I did so that it becomes opaque (if you want to try, be careful that the piece of glass may break because of the heat)- then, I used two crocodile clamps to make the contact (I've put a certain depth of aluminum foil between the claws of the clamp and the piece of glass)- then, I tried to measure the resistance with a multimeter, but the multimeter displayed no value at all.

Material Section

Hi there!I hope this is the right section to post this in, if not then i'm sorry i picked the most probable one (i hope D: ).First of all i love instructables, i'm using way too much time in on this page than i should, but then again if it wasn't or instructables i wouldn't have this cool new Hard Drive Speaker present for this cute girl i like ;)In any case let me get to the point; i would like to suggest a Materials Section for Instructables - basically it would include material stats and an in depth explanation of the material (or component if we're talking tech here, but that's a different area). Here's an example: in an instructable, the author mentions plexiglass and that it needs to be bent. Many don't know that plexiglass isn't class, but an acrylic hardened plastic substance with abilities much like glass (but not quite). Plexiglass can fracture, but wont leave extremely sharp pieces like glass will and it can be bent when under medium-high heat from a heatgun or the like. Also that high friction (from a drill or the like) will cause it to melt.Basically what i mean here is that this section would greatly reduce the time an author spends on making his ible by letting out basic facts. E.g. instead of writing "plexiglass is..blah blah" the user would be able to look up in the materials section and read in depth for him/herself what the characteristics are for plexiglass/plywood/capacitors/batteries and so on.The materials page could be powered by the "burning questions" competition i've seen on this page. I don't think material characteristics fit in ibles because it strictly isn't - it's a data sheet that lets you understand the materials and components you're going to use in an ible.PS: sorry about the lower case i's and the occasional typo or grammatical error i'm not a native english speaker . also i really hope this is the right section to post in...

As for the K-4: Everything worked the way it was designed to work, but certain mechanisms (the trigger and the BTS) required a lot of force to function, thus reducing the amount of tension that would be even remotely practical to use on the bow.  It was a good attempt and I have learned a lot from it; things that I will take with me as I move on to bigger and better guns. Here's a video for now, and I will explain everything in depth as soon as I can.

Greener Posturers - Hacking through the biodegradable, zero-carbon, ecochic overhype.

Here's a fun article from the New York Magazine.'s see: Green is the new black. Green is the new red, white, and blue. And green is the new green, or at least a new means of getting people to plunk down more of it. To some, the "green consumer" is an oxymoron (they might even drop the "oxy"). The real solution, they say, is to consume less. While there's some truth to this, a Walden-or-bust approach seems ill-suited to our present culture. Greed and vanity are alive and well; if they can be enlisted in the fight to save the planet, who are we to turn them away? With green-hype alert levels recently upgraded to orange, skepticism is warranted; here, our fictional sparring partners examine some well-intentioned products that mainly serve the buyers' self-esteem, and others that have unsuspected depths.

Ground Penetrating Gadget

Hello, out there, I would like to find how to build a ground penetrating gadget. I think there are a lot of 'us' would like to have something that can 'peek' underneath the surface of the ground, not necessary very deep. For example, such a gadget that can help fossil hunting tremandously. And it does NOT have to go all the way to Ground Penetrating Radar. As long as it can detect the differences between the matrix and interested object up to say 50 cm in depth, it will be good enough. And it doesn't matter what physical principle is used: GPR, ultrasound, electrical resistance or capacitance, ... (whatever). What I have in mind in such gadget would be tied to one of the shoes (so, it must be very light weight), using wifi to transmit the signal to iPad/iPhone so that the user can just walk and know the place to dig. Any help or comment will be greatly appreciated.

Firefox Scrapbook and Instructables "view all steps" issue

For each instructable STEP, I get to choose only one image to archive full size. I'd like to be able to archive ALL the images in a given step.Scrapbook DOES do javascript capturing... but the extra images aren't captured. So if i manually save the images, and put them in the right place, the scrapbook page will switch correctly, but that just takes SO LONG! Please help if you can.(PS, NEVER capture at a depth of more than 1. it'll quickly turn into a game of six degrees of kevin beacon and you'll end up downloading half the internet!)

Wiimote Head Tracking -- Nintendo: Please do this!

Johnny Lee did it again! Head tracking with the Wiimote!From his blog:"Using the infrared camera in the Wii remote and a head mounted sensor bar (two IR LEDs), you can accurately track the location of your head and render view dependent images on the screen. This effectively transforms your display into a portal to a virtual environment. The display properly reacts to head and body movement as if it were a real window creating a realistic illusion of depth and space. "I really hope Nintendo looks into this -- even though it only works for 1 person. After all, most games are 1-player, and those games are the ones that would best use this feature.If I had a bluetooth adaptor, I'd play around with this some, but, alas, I do not. However, this and his other projects would work the same with a video camera that has an IR filter.Funny, Sony really didn't take enough advantage of thier EyeToy, if it was IR-only, they would have been able to do more...

Be conservative

I don't mean take a right-wing political viewpoint as much as i mean be careful what you put in this group. Remember, if the book is published, we want it to have the best, the most interesting, the most rewarding instructables in it, not something that looks good but lacks any real understanding or depth, Quality of pictures, grammar and spelling should also be important. Furthermore, i don't think we should post our own instructables over anyone elses instructables. All the instructables here should be subjected to scrutiny and examined thoroughly before being posted. Don't just add your own instructables just because YOU think they're cool. Kiteman started this group so ultimately it's he who decides what can stay and what can go, but if we're careful in choosing a selection of good instructables over a wide variety of categories (K'nex contraptions, fun with LEDs, iPod hacks, etc.) then we won't need to leave anything behind. An example of a bad instructable is my own scalpel. Limited instructions for a very simple project. Bad piccers and spelling. That's the sort of thing we need to keep out. V

Need to make very loooong lasting battery operated Mini LED light for backlit painting

For some of you brainiacs Im sure this will seem like an incredibly easy project but for me, Not my area do expertise in the least. I need to make a simple machine for part of an art project. I need to have two small LED lights placed one each on the tip of two  clock hands . I need the lit clock hands to be battery operated ( looong as possible) and flattish ( maybe an inch in depth at most for entire piece) so it can hide behind a painting. Would like it to  operate lit up and moving in clockwise circle nonstop day and night for at least a year . Any ideas?  What # volt? How to make simple clock ( besides just buying a kit? It only needs a very long hour hand with bulbs on each end ( say 12 oclock and 6 oclock) Where to get small ( 1/8 to 1/4" diameter)  long lasting LED bulbs? As I said before, I am an absolute amateur here!  Thank you. Maggie

Laser TV Anyone?

While echo_anomie's laser projector is a finalist in the Laser Cutter Contest, a full-color laser projection TV was announced at CES. The LaserTV is coming from Mitsubishi and even though it's a 65-inch beast and is rear projection the footprint isn't that bad and the price is set to be on par with LCDs and plasmas of the same size.At home I watch movies on a 20" Daewoo that I picked up from Best Buy a few years ago because I needed it for work. It works fine enough for me, but I do like to keep tabs on the new tech so I occasionally go and check out the monster TVs that Best Buy likes to push. So far the colors and viewing angles haven't completely sold me enough to drop several hundred or a couple thousand just so I can enjoy the occasional DVD a little more.Still, I'm curious as to how these will look and maybe, just maybe, in a few years I might buy one. What do you guys think? And no discussing the depth please because these aren't that deep and nobody really moves their huge TVs around. link with slightly NSFW pics
