gyroscopic underwater camera stabalisation

Hi does anyone know if it possible to create a stabilisation platform to make a video camera point directly down all the time underwater. the ultimate goal is to attach one to the front of a Diver Propulsion Vehicle to map small sections of the sea floor. at the moment we planning to just have a guy being towed on a rope behind the main diver keeping the camera down Thanks for any advise Tom

Help with Stepper Motor and Slip Ring

Hi All,    I need to figure out how to get power and control signals from a stationary computer / PIC into a series of subsequent rings via rotating joints. Ultimately, what I want to build is a form of motorized gyroscope that can transmit power and control signals to the inner ring motors. - I'm using a Raspberry Pi 2 to control three Stepper Motors. - The motors are getting power from an old AC/DC wall adapter. - I currently have 3x NEMA 17 stepper motors     - Yaw Motor/Axis     - Pitch Motor/Axis     - Roll Motor/Axis - I've got 2x 12mm 12 8-wire slip rings that I hope can be used to send the control signals from the Controller to each motor. The problem is that I'm not entirely sure how to connect those components together, let alone how to connect them to bearings to minimize tension on the motor shafts. (I'm a software engineer, not an EE or ME.) An example of what I want to build is this:  https://www.instructables.com/id/Multi-axis-Phone-Stand-completed-Version/ ( However I don't need anything in the middle, I just need a way to control the rotation of each ring layer independently by the stepped motors ) If anyone can point me in the right direction it would be much appreciated, Mike C.

Skeleton Tracking Using IMU Sensors?

Hello, I found here on https://www.instructables.com/ a lot of topics talking about gyroscope, accelrometer, & magnetometer sensors. How they work, the idea behind them, and how to make use of the data returned by different sensors. Then stays the ultimate problem of filtering the data and getting reliable data. Then there's an online algorithm for that written by PhD student which is a very good algorithm. It'll be used on PC side as I understood from some gurus that such algorithms will get the arduino to its knees. There're some sensors out there that you may cost you a little more but they have the option to get filtered data directly from the sensors. Then comes the question itself. Is it possible? Well that was my bachelor project to read how other people did it and redo it. Then I remember the first time I was searching for how to work with these sensors .. it was a mess. Then I made a decision to make this thing available for everyone to play with. So far I implemented "Arm Tracking" and based on the idea .. anything else will be possible actually. I wanted someone (or some people) to help or brainstorm with me how can we make it easier for anyone who wants to start with the sensors .. from writing arduino library to simplify this .. to the "Skeleton Tracking" thingy. Even if it'll only be explanation but I wanted it to be one big guide for everyone just to pay back those who helped me with other stuff they were good at. Even if the guide is about gathering resources in one big topic and linking them together. I hope I could deliver what I wanted to say properly  :D Thanks in advance

DIY Steering Wheel

Hello, I'm new here. So, lately, I've been thinking about making a steering wheel for my PC, with a simple up-and-down gear box and 2 pedals for acceleration and brake. Steering Wheel. I'm using a polystyrene sheet, to cut out a wheel from it, and in the center, there's space for installing a phone holder. I'm planning to use my phone's gyroscope and simulate it to the PC. Pedals. I've figured by using foams underneath, we can place a nail and a foil separated and when we press the pedal, the foil touches the nail and circuit gets completed. I've a general idea, but I'm stuck on how to give that signal to PC as to simulate as a button (say for acceleration and brakes.) Gearbox. For the gearbox, I figured it might be easier to make an up-down box (as in pulling the level shifts the gear up and vice-versa.) Here too, The part where I'm stuck is giving the signal to the PC. Anyone who can help me, please?

High-Tech Peashooters with laser beams!

In this peashooter competition in the UK, some entrants have modified their basic tubes with some high-tech parts. This one uses a laser sight and a gyroscope to help aim. All of this is fine with the organizers who have allowed laser sights for a decade.Even so, the winner this year was someone with a regular peashooter so it still is quite a bit about skill. Pea shooters fight it out for world championships via BoingBoing

wiimote or a ps3 controler controling a self balancing skateboard...

I am looking at making a self balancing skateboard... i am having trouable finding step by step instructions for the ones that use the sensors... so i was thinking that if i could use a wiimote or a ps3 controler becuase everyone knows that the wiimote has gyroscopic sensors in it and the ps3 controller has a sixaxis thingie in it...(i know that thingie isnt the correct term for it...) so that gave me a good idea instead of piecing together gyrocopic sensors and many other things than why not just use a controller to control it... and if anyone knows another way to control a self-balancing skateboard... or a way to hook them up to the board... and i am not very good at programing so... if you could just send me a message of the programing to use the controlers as a controller than that would be great... if anyone thinks that this way is just to much harder than it seems than please tell me... thank you, Girrrrrrr2

Using a USB Bluetooth bundle into a home brewed device

Hey everyone, I am a student in software engineering and I am leading a project with other folks in software and electric engineering as some artists which consist of developing a computer game that use a home brewed device. That device is essentially a wii-mote ripoff: we will use some gyroscopes and accelerometer to get user input. However, some of the parts we are looking for are very expensive, we need to do 3 of theses devices and we don't have a big budget :) Since the most expensive part is the bluetooth transmitter (our device needs to be wireless), I was looking for a workaround. First, why bluetooth? Well we thought using some FM or RF stuff, however that implies some rare stuff that is not embedded in our student computers and even more expensive... So that's why we thought using bluetooth... And my question is... Is that possible and not so complicated to use those cheap USB bluetooth bundle such as these ones: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords;=bluetooth+adapter ? When I say not so complicated, I mean that we won't have a big controller... we will have just what we need to get the data from analogical sensors turn it into digital data and send it over USB. Looking over the web I found that some RS232 to bluetooth bundles exists, however they are very expensive... It might be an utopia, electrical stuff is really not my field of study. Thanks for your help!

Anti-gravity Machine concept

This is a concept I came up with for an idea of an anti-gravity machine.  Let me just state for the record... I do not think this will actually work.  However, while I am quite certain this idea should not work... based upon my limited knowledge of science... it would seem like it could work.  Unfortunately I know I am never going to spend the thousands if not millions of dollars to build this concept to find out. The basic premise of the idea is the use of angular momentum to overcome the force of gravity.  Imagine if you will, a gyroscope spinning at such a high velocity that its outward force overcomes the downward force of gravity.  Naturally, one of the big obstacles is generating the speeds necessary to create the velocity such that angular momentum is greater than downward force. What I essentially propose is a spinning ring that is propelled in the same way as a maglev train.  Using Electromagnetic propulsion or EMP to accelerate a ring in a vacuum by the utilization of a flowing electrical current and magnetic fields may in theory generate the speeds necessary for the force to overcome gravity.  Unfortunately, the power to run such a vehicle and the weight to power ratio are significant obstacles. Two of these rings above one another I theorize can create tremendous propulsion if the angles of the rings were changed.  Using hydrolics to change the angle of alignment of these two rings may create incredible forward momentum.  Once more, such a vehicle would not be limited to operation within Earth's atmosphere unlike jet or other propulsion mechanisms.  In fact, it should operate at peak efficiency in a zero gravitational environment. This is all theory... and I'd love to know if it is indeed as crazy as it sounds.

Make Magazine Subscription, possible that I will have an extra one for the right inspiration..

When I subscribe for another year of MAKE, if I can do so within a week or so, I will also be able to "give" a subscription to someone (this may be limited to the USA, I am not sure). All I am in need of is a spark (I have been SOOOO tired lately) of inspiration on something to create for either the Dremmel contest or the Craftsman one. I have in my work room, numerous ic's (from 555's to comparators, regulators, etc), an extra multimeter, a fair bit of "tin" i.e. sheet metal, two old hot air popcorn poppers, a few micro-amp meters, lots of bolts, nuts, leds, a few small gears and recorder guts, two electronic gyroscopes, some random pieces of a lot of things, including caps, resistors, inductors, diodes, and etc. I have been having a hard time of it being creative lately.....but if someone can give me an idea that is acceptable to me (inspiring), I would be able to get them that subscription.   One catch,  we will have to work through someone that everyone can trust as far as getting your name and address to MAKE if I choose your idea(s). Thanks for any effort put forth. . . The time I need to send in for my renewal is drawing close.....if ANYONE in the USA here, that is old enough to eventually share their mailing address (MAKE won't tell me if they will ship the free sub outside the USA or not), and can give me a decent idea of something to build soon,  I will subscribe and send them the free year. Most of the suggestions so far are from people outside the USA

Machined Spring Powered Car

OK, I think after posting in some of the other forums that maybe this is the best place. I have asked for some help in the Tech, Science, and Burning Questions Forum (Not sure if I should have started a new thread in each one for this project so if I should delete the other's please let me know). I am new to the forums and just signed up for a 2 year pro membership to help contribute as I have been viewing on and off here and there for the past few years. If anyone can help me make this, it would be much appreciated! I came across the object shown in the link below and shown in the attached pictures. It is the  "Toy Car" by the designer "Wouter Scheublin". It is a spring powered toy car made in the limited edition of 20. It does not look very complex, but does look elegant. It can be purchased for close to $3,500.00 US on the justification that it is art, but that is not something I will ever be able to afford for this type of object. I am not insinuating that it is not worth it (last year I actually contacted the designer as well as the people selling it for him to see if I could pick one up for substantially less).  In any case, please check out the link below for pictures and let me know where a good place to start making the components might be or just where to start in the design and build process period would be. I guess I would need to know the actual parts needed before I could start to assemble even something remotely similar and I figured the geniuses that use the forums here could help me (being that its December and in the spirit of giving and sharing and all) or maybe someone here might even be interested in possible making with me. Thanks in advance for your consideration and reply. See Link Below.  http://www.wouterscheublin.com/projects/toy-car/ On another note, I really really love this kind of gadget. Metal (or wood), Mechanical, Simple, Elegant. I have searched everywhere and have trouble finding a site specific to these types of objects. small precision desktop machines like a well machined Stirling engine or the like. (no need to be powered. Can anyone point me to a place that has such things. Another example of something I like (and did purchase) is the super precision gyroscope from gyroscope.com. http://gyroscope.com/d.asp?product=SUPER2 Another example of a mechanical gadget I would love to have or like to read about is. http://www.ohgizmo.com/2011/11/28/hypnotizing-video-of-the-worlds-smallest-v-12-engine-being-assembled/
