Cheap accelerometer?

Hello all, I'm building a textile interface using LilyPad Arduino and accelerometers to catch the movement and acceleration of points on this interface. As I intend to use a relatively high number of accelerometers (5), I've been wandering if there is any DIY accelerometer, or any cheap solution to it (as I'm brazilian, lilypad's accelerometers have a pretty high cost) . Thanks,

accelerometer controller

Hi I’m making an accelerometer (3-axis) that I want to be able to work in some programs and games. I haven’t built any tech´s before. Hehe so plz replay with easy words. There are some tutorials out there which are based on an old game controller and stuff. But I want to do my on an Arduino board with a USB connection or wireless connection. Here is a tricky part, I want it to fit a cube chassi that is around 7-10 centimeters, I haven’t done it yet so that’s why I put it to 7-10 cm because I have still time to make it bigger or smaller. I don’t know much about the wireless connection and battery to make these things. I know I’m sounding like someone that doesn’t have a clue about these things and it’s true, I want to learn it and make this controller. If someone can tell me more about this sort of project or tips me to a tutorial or something it would be excellent.

Sensitive Accelerometer Chip

I've seen some projects that use accelerometer chips with arduinos to get readings (e.g. in MATLAB). I'm looking to do this but I'm going to be measuring very low amplitude, low frequency vibrations so, I imagine, the types of acceleromters I've seen used (e.g. the MMA7341L) won't be sensitive enough. Does anyone have a suggestion for which accelerometer would be appropriate (I know that MEMS are a popular brand - there's a list here: http://www.analog.com/en/mems-sensors/mems-accelerometers/products/index.html)  Many thanks for your time!

Max number of accelerometers

Fairly new to arduino. Using it for a postgrad research experiment.Not sure if my googling is just shitty or if it can’t be done. I’m trying to do measurements of flutter for a flutter suppression system in a wing, and because of this I need to make a high fidelity computer model of the wing using accelerometers. I should be able to get away with six accelerometers and three servos, however from what I can see the ADXL345 only has two independent slave addresses (0x53 and 0x1D) so then I would need at least 3 boards (MEGA2560 currently). In this case I’m worried about bottle necking my control system. So first question is, is two the max number of accelerometers I can use? Second is, are there any better alternatives to arduino for this? Three, if I do need to use multiple boards, is there a tutorial for an easy way I can get them to talk to one another without going through a pc? Otherwise what’s a realistic delay between receiving the accelerometers data, analysing it on a PC and the transmitting a command to the three servos on a different board?

Detect Down, using arduino?

The desired result is a pretty simple one in this case.  I am curious how you can tell where "down" is, using electronics.  I'm sure It could be done by initializing gyroscopes in an initial, level position, but my friend has as small quad copter, that can take off at an angle, and be turned on at an angle, and still level itself perfectly. It doesn't have to have an initial reference to find what down is.  The other option is to use accelerators, but if you are making a device to control a rocket or multirotor it is unlikely to impossible that you will be able to isolate the 9.8 m/s^2 due to gravity from the linear and vertical accelerations,  I assume your everyday gyroscope outputs data in the form of change in degrees, so if it just sitting perfectly still it would just output 0 on all axis, but if it actually gives the current angle I would be surprised, and curious how this is done.  So in conclusion, how could an arduino accurately know where down is?

Some doubts: Lilypad Arduino, Accelerometers and E-textiles

Hello all! First of all, I'm a brazilian undergraduate Design student, and I'm very new at developing electronic projects (specially with e-textiles). I'm currently working on a malleable hand-held interface for my graduation project, and have been posting its development at this website: http://theinstrumentproject.tumblr.com/ Well, I've come up with the attached simplified schematics (just to communicate my needs and current intentions), and some questions raised from it: About Arduino and the schematic: - Will the raw data of the whole schematic (5 accelerometers to lilypad to bluetooth) be fast enough generated? - a frequency of 10 "readings" per second should be enough for what I intend to do with them. * - How much power will the schematic consume? Are three 20mm coin cell batteries going to do the job? In how much time would they be drown out? * About soft circuits and e-textiles: - What is best to transport data and power through this interface: conductive fabric, conductive thread or even a really thin wire? - It is important that it could be folded, twisted and very resistant through time. - Could you indicate any kind of textile more suitable for this application? - It should be just a little stretchy, and very resistant. - Any ideas of how should I protect the components from damage by rough hand manipulation? - Any advice about sewing the whole application? (*) The main components: - Arduino Main Board: http://www.sparkfun.com/products/9266 - Lilypad Accelerometer ADXL335: http://www.sparkfun.com/products/9267 - Bluetooth Mate Silver: http://www.sparkfun.com/products/10393 Hope someone here can bring me some light to these problems, but any kind of help, opinion or critic is welcome!

accelerometer based mouse, what happens when tilted

I got a free dual axis low g accelerometer from freescale, the output voltage is proportional to the g forces, I also have a ton of free PICmicro chips with I2C and A/D converters. I want to make a mouse just basically for proof of concept. I was thinking about how to program it, since I want to tell the computer the "movement since last request", I would need to calculate the speed using the g force reading (9.8m/s2 = 1g)if the mouse is moving at a constant speed, the g force would be 0, and the speed would be the same as the last reading, also, gravity affects the reading if the mouse is tilted slightly, increasing the speed even if it is not moving at all, so I was thinking, if the mouse was tilted, and then balanced again, the speed would remain the same, causing annoyance to the user. this is the problem i would like to solve.Is there a space efficient way to make a accelerometer not affected by tilt? if not, is there any tricks I can use (such as detecting unusually uniform g force and automatically go into "joystick mode")? I have been thinking about using a thumb button to zero the speed (while held down, the mouse can also do "super precise mode" which means one pixel per half second no mater how fast), is the thumb button the way to go? how about sensor to see if there is contact with a surface? or four IR rangers to detect tilt while above a surface?side note: does anybody have a datasheet for ata1060xa? its a optical mouse sensor with built in 27mhz RF transmitter made by @lab, and they don't share datasheets.oh and head on over to cypress for free wireless usb modules (2.4ghz i think, multiple channels) if you are interested in cheap RF, i have two with 50 meter rangeinfo on mouses and keyboard serial interface found herehttp://www.computer-engineering.org/ps2protocol/

Brainlink: atxmega, Bluetooth, rechargeable battery, accelerometer and more

It looks to me like I'm the only person on Instructables who uses a Brainlink in projects, so I wanted to share my experience with it.   The Brainlink is an atxmega with a cute case, Bluetooth module, a USB-rechargeable battery, accelerometer, multicolor LED, photo diode, IR transmitter, IR receiver, TTL serial uart, a bunch of pwm and digital and analog i/o lines and a regulated 3.3V output.   Full specs and official website are here.  It was produced by a Carnegie Mellon University spinoff. It originally sold for an overpriced $129 but unsurprisingly the product couldn't succeed at that price and it was discontinued.  SurplusShed has them for $39, which is more reasonable, and they periodically have 30-50% off everything sales if you sign up for their emails (for instance, they have a 48% off through the end of today with coupon code SS81420).  When on sale for $20 it's a lot of goodies economically put in one package (and you can pick up some lenses for Google Cardboard from SurplusShed while you're at it). The Brainlink seems to be primarily designed to interface computers or Android devices with all sorts of robotic devices.  There is an open source Java framework for talking to the Brainlink (though the serial protocol is simple enough to just roll your own).   I've used the Brainlink to decode IR signals (the official website has software for analyzing IR signals) and to control a Roomba via the serial uart.  Lately I've been using the Brainlink as a serial-to-Bluetooth bridge to talk to the Mindflex toy EEG (works better with my modded Brainlink firmware--the mods make it fast enough to capture raw data from the Mindflex: I will probably eventually write an Instructable)--see the photo. If you want to use it standalone, Arduino-style, you can upload your own firmware, either writing it from scratch or starting with the original firmware (source code is available).  I haven't actually worked with a real Arduino, but I was pleased to see how smooth the process of building and uploading the firmware was.  I just used WinAVR and it all worked just fine.  They have instructions and a link to the firmware source here. My own firmware mod was to add a full serial bridge mode.  Just send a 'Z' command to the Brainlink and until it's next turned off it bridges between Bluetooth and serial (at whatever baud rate you set with the regular Brainlink 'C' command).  The regular serial communication code may be OK for sending occasional commands to a robot, but it doesn't seem to work for sustained data receiving, at least not at the 57.6K baud that the toy EEG I was using works at.  With the bridge mode and an S-video cable, you basically get the functionality of a Rootooth for Roomba connection at a much smaller price. Presumably, with appropriate firmware you can make autonomous things, but I've been using it with a phone or a PC. For connecting stuff to the Brainlink, you use what look like 1.25mm spacing JST-style connectors (there is one 8-pin port and one 10-pin port;  for serial only connections, you only need three pins near one end of the connector, so a 3-pin connector works for serial).  They include one connector for each port.  I've ordered a bunch of 1.255mm JST connectors from a Chinese ebay seller--hopefully they will fit.   I have no affiliation either with SurplusShed or the makers of the Brainlink.

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

Advice for a simple bluetooth and tilt sensor device.

Hi! I'm new to electronics and want to create my own simple Bluetooth device. Basically I want to create a device with a screen that I can control using an app on a phone.  I'm planning on using a 3-axis accelerometer too, just to learn more about how those work and play around with some tilt options.  I'm working with a friend that is an EE student, but we still need some advice to get started. Basically I want to use a phone app to update photos or videos displayed on the device.  Also, I'd like to create a small program where I can tilt the device and move a ball on the screen.  Right now I know I need a Bluetooth module, a screen, and a 3-axis accelerometer but I have no clue which kind (there are so many choices! especially for the Bluetooth modules!).  We have somebody that will do the programming for us, so we just need some direction as far as the electronics go. Also, should I use something like adruino, or should we look for more experienced engineers to design it for us.  We'd rather learn how to do it ourselves though, and we don't have enough money to pay for a professional. Any advice would be greatly appreciated!  I'm starting to get very interested in electronics as a hobby, and would love to learn how to start doing these things! Regards, Patrick

Neo1973 or Chumby

HiI need your advice. I have been looking at the neo1973 phone for a while. It is an open source phone that allows you to do a lot. It has a touch screen,gsm,gps,2 accelerometers,and wifi. It is open source so there is infinite number of applications available. It costs about $400.Just recently I have been looking at the chumby. The chumby is an open source linux based mini computer. It has on 3.5 in touch screen, 2usb ports, wifi, and built in speakers. You can do a lot with its widgets (rss,weather,youtube,music,movies,flickr,facebook...ect) It cost $180. So I was wondering which one would you get and/or if you have any experience with one or both of the products. Thanks
