Mails about this

Joshua Wise (joshua@joshuawise.com) mailed me about an optical sensor chip with 'A2050' on it. Seems the chip is compatible with the A2051, which in itself isn't directly compatible with the ADNS2610, but the basic idea of reading the pixels of the CCD is the same. Joshua created a program for Linux to read out the sensor; it's here. Another note: Some mice have the Vcc of the sensor switched by the microcontroller; if you try this hack with such a mouse you'll need to connect the Vcc directly to the sensor chip.

Carsten Gross mailed me:

I'm working on an university project (http://www.siski.de/~carsten/diplomarbeit.html) and I'm using your webpage as base for my idea to use an optical mouse as motion sensor for a model car.

I removed the original optics of the mouse and replaced it with a lens with f=4,6 mm. To check wether the image of the world (as seen by the mouse sensor) is focussed I'm using a modified Linux version of the software downloadable on your page: as my mouse has a ADNS-2610 (and not one of the older chips).

Please see the attachment for a modified version of the software by Joshua Wise now running with the ADNS-2610 and Linux.

Using the different optics the focus is now near infinity. This way the sensor can be mounted at a safe place in the model car. Perhaps it is necessary to add specles on the floor ;-)

The source of the software is downloadable here.
He mailed me a second time:
Im the meantime we built our own board with the sensor chip here and use it as movement and direction detector.

Please see this for the images of the sensor board and the lens. I connect the synchronous serial port of the ADNS-2610 with some simple "glue" logic to the SPI interface of the Atmel AT91RM9200. This way I can use the Linux-kernels and microcontrollers hardware support for reading the data from the motion sensor.

The lens is adjustable and the focus can be adjusted to generate a sharp image and the maximum "quality" value in register 4.

EaterOfPies mailed me: "This also works with A1610 / ADNS-1610 sensor IC. It appears to be pin compatible but i couldn't find any documentation on it."

I have received several questions about using this device as a barcode-scanner. Yes, that would probably be possible, but one would need the right software for that, and I'm not interested in writing it. If you think it's a good idea; knock yourself out; the sourcecode of my program is provided in the zip-file :)

If you used this information or software in any useful project, I wouldn't mind being mailed about it. One thing: mails containing not much more than 'It doesn't work here, help!' will be deleted.

Had an intriguing idea: for those times you need "autoland" because your drone decided to lose comms thanks to interference this would work well. Have it also detect low battery and if comms drops out it cuts motors to 30% and begins a slow descent a bit like a lunar lander, with ground detector to shut off motors completely.

Hi @all. Google is your Friend! I know it is not quite easy to find this Sensor. Mouse of Logitech - M-BT58 named "Skipper" would help you. On the other Hand google for the Sensor. It is possible to buy this Sensor in Elektronic-Shops in Germany. But the newer Sensors (with Picture Transfer) came nowadays from Taiwan and nowhere else in the world. This dismisses!

SarahC wrote at 25 Mar 2012, 8.15:

Hi Ed! On the previous page, you say to cut the wires to connect it up to a serial plug. If I do that, the mouse will no longer update the computer with its position information. I didn\'t see the scanner software mention that it had any motion-flow algorithms, so I imagine it was doing it the easier way, and sending the output of the CCD as pixel information to the position on the screen the OS mouse was at? If that\'s the case, doesn\'t that mean the SCK- and SDIO-pins should be just soldered to, so the socket is plugged in parallel to the normal tracks? If so, doesn\'t the voltage drop cause problems? Thanks for a very interesting hack! Sarah@Untamed.Co.UK

ed wrote at 19 Feb 2012, 21.14:

this is interesting, but for those posting about obtaining the image for tracking and guidance purposes, you may be best leaving the scanning and image processing to the very capable hardware inside the chip. optical mods to infinity, maybe with an electronic variable optical zoom lens, could be the key to ultra low cost guidance systems for small drones and missiles. simply using the x,y info from a mouse usb with infinity focus will give enough data to lock a missile onto a moving target in a clear, or at least low contrast sky. infra red sensitivity is good enough to read a turbojets heat signature for a night lock even more secure. these chips contain pretty much the same tech as top of the range weapons systems of 20 years ago but a less than a dollar a piece.with the current exploitation of off the shelf technology, it would be little wonder if mouse tech was found in guided missiles less than the size of a rubber bullet. certainly the electronics and power would weigh in at less than 10 grams

My plan is to use it to read the last 2 or 3 digits of the LCD on my gas meter for allow me to track gas usage... A completely non-invasive method that is 100% accurate for energy monitoring purposes. The hard part is OCR on the image in a micro controller...

Anonymous wrote at 10 Mar 2010, 5.42:

If anyone has a question about the frame rate of that method it is because although the internal image processor has access to the image at 1500 fps the chip was never intended to send that image across the serial line in real operation, that is more or less a debug feature and when you request the raw image it doesn\\\'t just store the current image and send it to you, it actually sends you the first pixel of the first image then the second pixel of the next image and so on and so forth. what this means is that its 18^2 times slower than the actual frame rate which is seen by 1500/18^2 = 4.629 repeating which is pretty close to the frame rate you observed. And now that I\\\'ve typed all of that I finally looked up at the post date, oh well maybe someone will find my rantings useful. I\\\'m actually thinking about modifying one of these things to mount to the underside of a robot that\\\'ll travel at around 10 fps so I figure if I raise it 12x its designed height and focus it then it\\\'ll work in counts per foot instead of counts per inch and handle the higher speed.

Sprite_tm wrote at 26 Nov 2008, 11.41:

Not really; the device can only send one pixel off each frame it grabs back to the host device, that's what makes it slow. The sw was written in VB6.0, but might work in 5.0 too.

I've been looking to build a small *cheap* 3-axis computer-controlled robotic positioning system and have been considering using the innards of cheap optical mice for position encoders. Was thinking of mounting a disk on each drive axis with dashes printed on the outer radius and using the mouse to count the dashes as they move past. I figure I can get pretty good accuracy, depending on how big I make the disk. Your code looks like a great place to start on this endeavor. Is the chip you used something I'd expect to find in a no-name optical mouse that I can pick up for a few bucks at the computer store? If not, can you recommend a particular model? Also, if you have any different ideas for a cheap encoder? Saw optical mice on sale for $3 each the other day, which is pretty cheap! -N

As a response to the people who asked about the diode... any diode is fine really... I used an 1N4001. Connect the cathode to pin 5 of the printer for and the anode to pin 12. The ASCII schematic tells you to that pin 3 of the sensor is the data in/out pin. It goes to the connector pin 12 directly, and to pin 5 via the diode.

Perhaps this sensor would lend itself to autonomous tracking (of aircraft let's say.) A 'rougher' stage would direct the PZT (Pan Zoom Tilt) platform in the correct direction. A fine resolution co-axial 'zoom stage' would keep things locked on target. Additional fixed position 'rougher stages' continue monitoring for multiple targets. A pc would co-ordinate target allocation. Everything gets recorded to DVR. Basically this is a robust transient event detector/logger. triox_compound@hotmail.com
