speakers

Hey you guys are all so creative and knowledgable, this site is so great (tho terrible for my procrastination) does anyone know how to build a speaker to fit certain dimensions? like how flat could i make a speaker, and how loud would it be for something only a half inch thick (if thats possible) and up to 12" wide? it is meant to plug into an mp3 for power source etc.

Capturing thin parts in 123D Catch

I'm new to the 123D world and have a question about capturing thin items like handgun grip panels. Is it better to lay something thin down flat or would it be better to somehow stand it either on edge or on the bottom? I want to try to print some new panels and plan to start with the capture program. Thanks, Curt

My monitor screwed?

I've got a 19 inch flat screen crt monitor hooked up to my mac. And when I play my music really loud, the image almost shakes like it would if I had the stereo hooked up to the power bar with it like it used to be. The stereo is on it's own breaker right now, but is it doing that from the actual vibration of the picture tube or is it dieing on me?

How to run a 20" flatscreen tv with a portable power source?

I'm wondering how to run a 20" flat screen tv on a portable power source. Would something like a car batter work? Or like a billion 9 volts? I need to be able to take the TV outside and walk around with it for about an hour at a time.

Large NC (Normally Closed) Switch

I am currently working on a project which requires a larger NC switch. The concept is that when someone sits on the switch, the current will be blocked and not flow. When the person stands up, the current will flow through the circuit. This specific switch has to be flat enough for someone to sit on. Does anybody have any ideas on how to build one?

Help identifying/replacing component

I'm trying to repair an iMac (Flat Panel) that has non-functioning USB ports. I've narrowed it down to this component, but can find no specs on it. I'm assuming it's an temperature/current protection component and appears to be in parallel with unused fuse pads. I'm wondering if I can get away with sticking a 2amp (it drives 3 ports) fuse in there and bypass the component. Any help would be greatly appreciated.

spray paint shoes

I needed to change the colour of a pair of synthetic upper boots for a costume party, and this what I did. Firstly, I used spray paint. Even though I had sanded the surface, the paint would not adhere. In desparation I then used cheap acyrlic paint. Did the job superbly. The only problem is that acyrlic paint dries flat (no shine) but luckily my DH had Gloss Medium in paint box.

Small Radio-Activated Alarm / Key Finder

Hi Guys, I'm quite new to electronics (I'm a programmer by trade), but I'm a quick learner. I want to make a sort of radio Key-Finder (similar to something like this), but I'd like the "receiver" end to be rather small in size.  I'm trying to figure out how to go about starting something like this, but I would really appreciate some direction. Some questions: 1.)  Are there products that I can take apart and re-purpose for this? 2.)  Could something like this, for example, be a starting point for the radio "receiver" end? 3.)  I imagine that I would need at least a small battery (flat watch battery?), perhaps a small flat Piezeio-Electric buzzer (like one of these?) and the radio receiver. 4.)  Is this a project that needs something like an Arduino board to handle any logic? 5.)  Can I re-purpose a car alarm remote for the "remote" piece? Thanks for any thoughts and direction. Dan

Need help finding a suitable white plastic stick . . .

I have a project I'm working on and I need help finding the plastic version of this: http://factory.dhgate.com/toothpicks/gl160-sandwich-picks-88mm-750pcs/box-p41597072.html or this: http://www.webstaurantstore.com/wooden-food-picks-flat-750-box/999R823.html I have been searching and searching and searching for about two days straight and I got nothing. I've looked up craft sticks, stir sticks, swizzle sticks, food picks, appetizer picks, cocktail picks, fruit picks, sandwich skewers, dental mixing spatulas, you name it. It doesn't have to be exactly like these examples, it just has to be white, it has to be plastic, it has to be flat, and it has to be about 3.5" to 4" long. I know I've seen something like this before but I just can't put my finger on it. What better place to ask help than the most resourceful group of people on planet earth?

Need help with Led project (time sensitive)

Need help with Led project (time sensitive) Hello I am currently working on a project that has less than 3 weeks till the suspense date. One aspect of the project I will be adding some LEDS. I want these LEDs to flash. So I got the following stuff for this project: LED Flashing kit MK102 by Velleman from Fry’s Electronics 100 rectangular flat clear 2mmx5mmx7mm LEDs (DC 3V 20mA) 400 DiCUNO 3mm LED assorted colors Forward Voltage: R/Y 1.8-2.2V B/G/W 2.8-3.2V Max Current: 20mA The issue: Ok so I want to take the LED flasher kit and instead of using the two supplied red LEDs I want to run two series of LEDs. One series will have two flat clear LEDs and one clear 3mm LED. The second series would have one flat LED and one 3mm clear LED. I have other colors but I figure if I stick with the clear LEDs, it makes everything simple and I will simply paint the LEDs the color I want. I would like to use all the other circuitry that comes with the kit and simply add each series where you would normally add the two red supplied LEDs. This kit runs on a 9 volt battery. So, I am assuming that I can simply replace the supplied resistors that come with the kit with ones that account for the LEDs I want to use? I am attaching the diagram from the kit for clarity, I hope this is making sense. Any help you can offer would be appreciated.

Soundproof Sleeping Closure

Hello fellow instructables :) Right I need some help and advice on a design brief to help fix my problem. Problem - I live in a ground floor flat and there is 1 flat above me, 2 scum bags occupy it, a couple of 22 year olds and they have obviously never been taught consideration for others and they bang and thrash around all through the early hours of the morning. When they bang on their bare wooden floor it sounds like a heavy metal dumbbell coming through my ceiling and it wakes me abruptly and its ruining my life :( I've complained to the council the past 18 months but there not interested. They have not put any carpet down in their flat in the last 18 months and it looks like they have no intention of doing so (they can afford fags n booze tho), plus they have a baby due any day now, great.. so now there making their problems, my problem. Solution - The only thing I can think of is making a soundproof sleeping closure, a large box like a 4 poster bed but all sides solid made out of a layer of MDF then insulation then more mdf, but I have some questions before I start. How would I get adequate air in and out ? Would this even stop the banging on my ceiling waking me up ? or would it still penetrate the box ? How would I control the temperature, would it be too hot in there ? Something like the image below but more solid with a door. If anyone has any experience with this or input or any good ideas I'd be ever so grateful. Cheers in advance. Matt

A revolution in laptop mice?

Slide up /down wall mount for flat monitor/tv

Hello fellow builders! Title says it all. I would like to build something like this project: https://www.instructables.com/id/TV-Lift-Cabinet-in-under-three-hours/ but without the motor and closet.  I would like to attach a monitor to a metal plate (or rails). This plate has to be attached to a wall and be able to slide up/down that wall vertically. I will manually pull it upwards (weight monitor is 10 pounds max) or push it downwards. And it has 'stay' in the position I pulled it up to, but sliding up/downwards has to be easy. But there's one catch: I do not want to see rail's or something on the wall ABOVE the monitor when it is in its downwards position. Also it would be nice if it was as sleek as possible. Does somebody know what kind of sliding mechanism I could make/buy that could be suitable for this task? I've done a lot of asking/searching but no one seems to have any usable tips! Many thanks!

Halloween blinking eyes LED project

A pair of red LEDs which blink in an approximation of the glowing red eyes of some baleful critter lurking in the shadows behind me as I hand out candy to the kids. I figure to poke the LEDs through a piece of cardboard sprayed with flat black paint. Half a dozen sets of light would make for a pretty scary pack of, well, something. Just the thing for Halloween. I don't have the technical background to do this but it seems like it might be fun and cheap.

deck baluster

We finally have to finish a deck rail - I need an inexpensive idea for balusters or something that won't completely obstruct my view. I don't like the 2x2's, or lattice. I do like the look of aluminum/metal in plain black - either square or flat - but hate the thought of spending $250 just for the balusters. I love the look of balcony panels - but getting a plasma cut piece of metal for each section is way way more than I want to spend. I'm looking for the dirt cheap alternative.

A good adhesive.

I'm doing a project for a high school competition in which I built a computer and plan to skin it. I've got my skins draw and (soon to be) printed. Heres my issue, how to attach them to the computer case? I need an adhesive thats heat resistant and won't ruin as the computer warms up, it also needs to be flat in that the skin does not stick away from the case. (Some sort of spray adhesive or paint on glue). If I could get any suggestions or a good brand name I'd be very thankful.

Less then 2 yr old flat screen - has died....I believe...

My 17" Gateway flatscreen went blank this morning while I was at meeting. My wife claims she didn't do anything.....that it was blank when she saw it. It was not in sleep mode, nor was a screen saver on. I noticed the "power button" which is normally green (power up, with computer signal) or amber (powered up w/out signal), would not come on. I attempted to see if any of the adjustments on the side might have been bumped, no effect. I tested to make sure there was power from the surge protector (switched power outlets after a shut down) to no avail. After my 4th reboot, I subbed in my old monster sized 17" CRT tube monitor, and it works fine. Resolution is different, but it works.....but that pushed the monitor about 2 feet closer to my nose then I would like (it is about 10 inches from my face. )Did I miss anything as far as testing the monitor before replacing it? I personally think the PSU in the monitor went on the fritz, but I am open to suggestions. EDIT: The old CRT is now back ni it's storage area, and the newest LCD screen is up and running.

Pancake Coil

Hello, I was going to try building an old Tesla "Pancake" Coil, and then write an instructable for it. (please don't steal my idea!) Does anyone have any information or building techniques at all that they can give me to help? The Pancake coil is just a Tesla Coil that has a flat secondary, as well as a flat primary. Tesla used it in his early radio and wireless power transmission research. The primary circuit should be pretty much the same as a conventional Tesla Coil. But I am a bit confused as to how to build the secondary. A few questions I have: What wire gauge should I use (I'm pretty sure that Tesla didn't use magnet wire for this)? How do I determine the space in between the turns? (more to come) I realize that most people don't build these kinds of coils anymore, and therefore most people probably won't be able to answer my questions or give me any info; I'd just thought that I would try and see if any one could. It would help me a lot. Thank you.

Particle physics question for Kelsey or anyone else that can answer....

I am finishing up the book I am reading on Dark matter, and Mr. Krauss mentions "spontaneous symmetry breaking" (not a hard concept) creating or producing  spin-0 particles or scaler particles  (Higgs Boson?).   My question is, have any of these particles, as yet, been observed?  The book I am reading is slighty dated, and so I am not even sure it is up to date on the vacuum energy  postion towards dark matter and a flat universe.

Laptop's fingerprint reader, is it possible to reuse it on desktop?

The dead laptop is a HP Pavillion dv3 4010sl, the sensor is a Validity VFS301 (cdk1071_r04_hf) as written on the sensor itself. if i remember correctly it was shown as a USB peripheral. maybe is simple and it need just some resoldering to a USB cable, the problem is that the flat cable connecting it to the motherboard has 6 pins/lines and my knowledge in electronics is quite limited... I've found online what seems like a motherboard schematics (pg.48) and the vendor's sensor's manual. Does Anyone knows if is possible, If yes how?

Design suggestion needed - simple plastic slider for small boat transducer

Hi.  I need to add a small sonar transducer (fishfinder sensor - small 2"x3"x3") to the transom of a kayak.  The transom is the flat backwards facing keel-like appendage in this picture.  It is ~3" wide and a foot vertical.  There is a hole in the hull directly above it, so it can be accessed from above. This shows the kayak transom http://i960.photobucket.com/albums/ae87/nickmdal/Bassyaks%20photos/IMG_4068Medium_zps318a10df.jpg The transducer  needs to be able to slide up 2 1/2", so that it won't get dinged when transporting the kayak.  Therefore I want to attach it to something that I can slide up, but will remain attached to the transom. Envision something like a paint stir-er flat against the transom in a vertical orientation.  From above, I can grab the top and pull up to raise the transducer. I am imagining the transducer's "holder" to be some sort of rail/guide combo that is friction and not wheel based.  I found these items, but nothing any more useful. http://www.soucyplastiques.com/en-CA/_media/image/big-glissiere.jpg Other thoughts were drawer center rail siders, tie/belt sliders (a hacked one).  That and the pic above are all I could think of.  Any suggestions would be so appreciated.

Price of regular white LED's???

I just came back from my local electronics store and was kind of shocked to find that the price for a white LED is 2 bucks from where I come from, which is about US$ 0.62 each! I was thinking of buying 100 of them which ends up around US$62.00!!! Is that the standard price? It doesn't look like the regular LED, it's somewhat smaller and shorter in size, with a flat head instead of the usual rounded ones. But the price difference is so big! The standard round headed one's are only US$ 0.09 each! But the funny thing is the salesperson told me that round headed LED's DO NOT come in white, only red, yellow and green! But in fact I bought them before from another store but sadly they are out of business now so there's only this other store left in my city. So my point is, is that the standard price at your local store? How much do you pay for a single white regular LED? PS. by 'regular', I mean those with rounded heads and can commonly be found almost everywhere such as toys and decorations. Also I'm not referring to those high powered LED's used in modern flashlights. The pictures below shows the regular LED, and the one which I saw at the local store which has a flat head.
