How to pull a tooth?

How do I pull my own tooth? It is a molar, ( the third tooth back from my K-9). I have an ex-ray of it and the roots are straight. I have a strerile set of tooth extractors, and a tooth elevador. Also lidocane, and a sterile syringe but I'm not sure if I can use it or if it'll work, or where to place  the shot.

How to add and power a Bluetooth receiver to battery powered speakers? Answered

I have a iHome speaker that is powered off 4 AAA batteries. I want to add this bluetooth receiver to the speaker. The bluetooth receiver is powered off USB, but I want to keep the system battery powered.  Can I take apart the bluetooth receiver and solder the power connections to the power connections on the speaker?   The speaker is powered off 4 AAA batteries, so 6 volts.  (How many amps??) The bluetooth is powered from USB which is 5 volts, correct?   Would the 6 volts from the AAA batteries damage the bluetooth receiver?  What about current?

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) ?

Adjustable Signal...radio, bluetooth, etc.

I am trying to figure out how to control a device that will be "off" while in the range of a transmitter (short range...under 10ft) and then turn on when it goes beyond the range of the signal. I would also like it to be an adjustable range. I was thinking the device would be "on" constantly as the transmitter tells it not to activate, but once it leaves the signal range it would activate.  Any thoughts? Thank you in advance.

Induction Charging ? Answered

OK, I have disassembled a old electric tooth brush and I am trying to reduce the size and one of the things I have deemed unnecessary is the PCB that runs the timer built into the toothbrush. However, one thing I am wary of at this moment is that the toothbrush is a induction Charger which is a A/C and I don't know if I can just remove the board and be OK or do I need to rectify the current into D/C to continue charging the battery. If the latter is the case what do I need to achieve this?

Heavy aerial lift quadcopter?

Hi, I am in a local competition where they are asking for a quadcopter that can lift a box of lead. The box weigh's 25kg. Yes, you read that right 25 kg. The rules state that it must be a quadcopter and it must fit in a meter by meter by meter cube. This limits the prop size to 500mm diameter unless the height of the blades is different so they overlap. I would prefer not to do this. each rotor must lift 7000 grams (payload + weight of quad). I have been using this thrust calculator : http://personal.osi.hu/fuzesisz/strc_eng/ and according to it a 500mm (20") at 4.5" pitch (I just put that as standard) will need to spin at 6000 RPM to produce 7.12 kg of thrust. It also says it will need an 800 Watt motor. I plan on using these motors http://www.hobbyking.com/hobbyking/store/__24433__NTM_Rotor_Drive_450_Series_1700KV_930W.html. They are 930 watts and 1700kv. they run on a 6s lipo. A 6s lipo is 22.2 volts. 22.2 X 1700 = 37,740. 37,740 RPM is the theoretical speed of the motor. I only need 6000 RPM. 37,740 / 6000 = about 6. so the motor has an 8 tooth gear on it and the prop has a 42 tooth gear on it. This makes a roughly 6:1 ratio to slow down and power up the rotor. The motor is 30A constant current, 42A burst. The ESC will be this one http://www.hobbyking.com/hobbyking/store/__25366__Turnigy_Multistar_45_Amp_Multi_rotor_Brushless_ESC_2_6S.html and the battery will be this two of these: http://www.hobbyking.com/hobbyking/store/__9176__Turnigy_5000mAh_6S_20C_Lipo_Pack.html.          When I started writing this I had a question that I answered myself but now I just want to know if you see any faults with this. PS, the winner of the competition is the one who can hover the longest. I also want to do it for as cheap as possible

PCB etching left over paper

Hey everyone! I'm in the process of etching my first PCB. I have a few questions. I'm using the toner transfer method, with hydrochloric acid and a little hydrogen peroxide as an etchant. Anyway, I transferred the toner to the board, but I believe the glossy paper I used may have been a little too thick. The toner transferred correctly, but i can manage to get all of the paper off. I've tried a tooth brush and a soft towel. My question is, if I just go forth and etch the board will the paper dissolve with the copper on the board and give me a clean result anyway? Will the copper covered by the paper not be removed? are there any cons to this? (such as not being able to reuse my etchant) Thank you all, your help is appreciated Ken

Best way to cut plexiglass without a laser cutter?

I need to cut a 9" diameter circle out of a 12"x12", 1/8" thick piece of clear cast acrylic (making an infinity mirror). I've cut this stuff with laser cutters before but don't currently have access to one. I have a circular glass cutter but I'm not really clear how that does me any good - it scores a circle but the acrylic doesn't seem brittle enough to snap off nicely along a circular line. I have a jigsaw with a wood blade but that just snagged and made the acrylic shatter. I have made rectangular cuts before by scoring a straight line with a utility knife, then lining that cut up with the edge of a table, and hitting the suspended piece of acrylic with a mallet - it snaps right off. I'm just not sure how to make a circular cut. Finer-tooth jigsaw blade? Approximate it using the score-and-snap method for a many-sided polygon with a bunch of straight cuts?

How to create linear motion from non-sinusoidal angular rotation? Answered

Sorry, I coudln't think of an intelligent way of snap-shotting my question. Here's the deal, I have this lab test tube rocker, which oscillates the platform back and forth like a see-saw. It works just like a piston engine, with an electric motor that has something like a crank, and something like a connecting rod, such that it converts angular motion to linear. You probably know what I'm talking about, but I've attached a photo. Because it oscillates on a sine wave the platform spends an equal amount of time at every phase of the wave. But I want it to spend more time at each end of the oscillation, the peak and the trough, more like a sigmoidal curve. What do you think would be the best (easiest) way to do this? Mechanical or electrical? Mechanical seems cumbersome. Have the pin on the crank "float" (so that it has a variable radius) and then have it follow an elliptical (or sigmoid) track? Or have the crank be toothed gear that turns a track that could be shaped over an elliptical or sigmoidal shape, and have the pin come off the track? That seems unnecessarily complex. The easier option (I think), would be to create a timer/switch so that every 180 degrees of rotation, at the ends of the oscillation, the timer turns the motor off for a second. But I have no idea how to do that.

Toshiba Dvd Player Problem

This lady gave me an older dvd player (Toshiba SD-2150) and she had it hooked up at her house, but the cd started skipping about half way in, and it would contiunously cut out for 10 seconds then resume playback and then cut out again and so on and so forth. As you'll see in the pictures, I've taken it apart down to the laser assembly (only took me 10 minutes incase you're wondering). The apparent problem to me is something is wrong with the gear assembly that moves the laser head. When I turn it by hand, it moves freely for about half a turn then it feels like the gear is catching on something, and if I turn it harder it keeps moving, it's not stripped, but it almost "feels" like theres a hump in the gear or something. I keep looking at the gear and nothing looks wrong with the teeth or anything! I was just going to put 3-in-1 oil on it and see how that helps and put it back together.  Does anyone have any suggestions? *********UPDATE********* I tried many things with various tools I had sitting here to try and straighten out the one tooth on the gear with no success. However with the little bit of melting/bending I did and the 3-in-1 oil, I got it to catch on the gear less easily. After re-installing the optical assembly and testing it on my stereo with the cover off, it appears not to skip anymore, DVD's too. However, I'm still not confident in how long this "repair" is going to work. The best solution I think is to replace the smallest gear on the motor, but I cannot find one close enough.

laptop backlight question? Answered

Long story short.  Room mate got bleach on his Toshiba laptop.  It spilled into the port of the usb area, hdmi, network cable side and he said it instantly cut off. He tried turning it on and the power light would just flick off. (he also borrowed my movie that i rented from the library)  After drying it all day we took it apart and noticed the bleach had corroded the usb port. I remembered in my college days that shorting a usb port will cause power supply to cut off. So i said lets get some CRC QD cleaner and just clean the corrosion and it should work. I couldn't get any electric cleaner but the people who work across the street had some non chlorinated break cleaner.  We used that to clean as much of the corrosion as possible off the usb and noticed some on two of the chips on the motherboard had corrosion.  Spent about 20 min cleaning each pin on the chips to separate them and tried powering it again.  (at this point the laptop is mostly apart and just got bare essentials put together).  It worked, fans started spinning and screen flashed its toshiba windows didnt shutdown logo. I begin to assemble it as much as possible without putting any screws in. I got the keyboard in and every electrical component.  i mashed the power button and the backlight on the screen wont come on.  I can see the text on the screen change but no light. Take the keyboard out and it works normally.  Can someone help me, or got any pointers?  I'm away from home so I dont have access to fancy equipment like tooth brushes or contact cleaner.

Can you point the way to a DIY audience response system?

Audience response systems are invaluable tools in classrooms but I can't afford the $1.2K that companies want me to spend for a pack of 24 units! I've got 35+ students in my class! Background: Electronic audience response systems allows admins to poll a large number of users on a large amount of questions.My students (G9-12), in general, do have (newish) cell phones. (New cell phones, like new tennis shoes, are a status symbol and among even the poorest students I've seen them with new expensive cell phones). Most students do not have wireless enabled laptops/handheld computers/ accessible in the classroom. What's worse is that many school network admins flat deny student access to school's wireless for fear of security/porn/ inappropriate material etc.The open answer/polling time would need to be able to handle responses from a variety of inputs at different times i.e. little Johnny takes a little longer than Janey to answer the question so we can't have to wait for one student to enter their response before the next student. This time delay in fact would nearly defeat the purpose of gathering responses efficiently.I'm very interested in seeing if a blue tooth receiver/software package could handle the polling of 30+ cell phone connections at the same time.Your help in this matter has enormous potential to achieve a Johnny Lee wiiboard like effect on classrooms worldwide.Alternatives: paper pollingAs noted below, paper polling doesn't scale very well. If I'm performing secretarial duties of sorting paper then I'm not doing my job as a manager of a classroom and education. I feel that any teacher that is still pushing worksheets/quizzes/ etc. on paper then that teacher is working too hard and not working smart.IR remotesI've looked at trying to use off the shelf IR devices that could be used as a polling device. I believe the problem is in the IR receiver being able to identify each individual IR device. How to mod an IR so that it only has a unique signature connected to each signal?
