Thanks! It's always great to hear first hand experience. I'll be making this mod to my S1 in the very near future.

Re: Raymarine Gyro Sensor Upgrade for $25

I have now finished my Gyro project. Used Sparkfun Gyro Breakout - MLX90609 - 150 /sec and some bits from local electronics store. Installed in a box and mounted in centerline in engine room under cockpit. Conducted seatrial and result was impressive: very accurate steering also in waves under spinnaker.

Some pictures here:




Big thank you Fulup, Portanna and others making this possible!

looks great!!

I'm trying to achieve something with Arduino Uno and the LSM303. So far I get nmea strings as output The only thing that bothers me, the heading is nog stable while laying flat and untouched on the table.

How did you reduce the 'noise' from the output?

Regards, George

Re: Raymarine Gyro Sensor Upgrade for $25

The enclosed link shows a video of my setup for a electronic compass with NMEA output. The system has a tilted output and for noise reduction I used a moving average. Hardware used:
- Arduino Uno
- LSM303

To do: build a rs232 to tty converter

Re: Raymarine Gyro Sensor Upgrade for $25

For the less adventurous, I have found a retailer who sells this gear for 132 euros:

http://www.ebay.es/itm/ws/eBayISAPI....E:L:OC:GB:3160

or

ray giro raymarine - TECHNOLOGIE SEYMO

No connection to the seller, other than I just brought the gear - will report after delivery and installation.

Nice. Could we get some more details?

Re: Raymarine Gyro Sensor Upgrade for $25

An update. To create TTL output from the Arduino board, I build the circuit board according to this drawing:
prosje.be/CO/Schemas/RS232-to-TTL3.png

The moving average filter does not work too good, so some other sort of smoothing is required. On various forums I see topics referring to the Kalman filter. Since I'm not a C++ programmer, this is quit a challenge for me. Any help is highly appreciated.

To give you an example of the data stream while the compass is laying flat on the table:

Maybe you should start a new thread. I suspect there will be a good amount of interest in your project it just needs to be out there.

Re: Raymarine Gyro Sensor Upgrade for $25

I have an S1 without the gyro. I was about to crap on this auto helm until I read this post. Would someone like to build me a gyro to connect to me S1 and send it to me for a fee? I would be willing to pay $100 plus shipping on top of what the parts cost via paypal. Message me if this will work for you. I would expect this unit to be first tested on your boat first to ensure it works.

Thanks

Joe

Re: Raymarine Gyro Sensor Upgrade for $25

OR can someone link the parts that I will need for this project. It appears if I screw it up, the $25 it would cost to attempt is not that much of a loss. Thanks

Re: Raymarine Gyro Sensor Upgrade for $25

You can use a MLX90609 or a ADXRS613 it is reported as working and they are still easy to find. If you do not feel confident enough for cabling by youself, the easiest way is to ask to an electronic shop near by. They are only 5 cables to connect, and it is very simple.
I'm too lazy to translate the orriginal post from French to English by I reply to English comment. In the mean time googletranslation with picture might be good enough Google*Traduction

Re: Raymarine Gyro Sensor Upgrade for $25

Did your gps gyro work for your raymarine unit. I would like to install one on my machine.

Re: Raymarine Gyro Sensor Upgrade for $25

This thread has not had any new entries in awhile. I'm trying to do a gyro for my S1. The gyros that were mentioned here are no longer available. I have ordered a couple to test out and see if they will do the job. One cost $3.00 and the other cost $30.00. If either of them work, I will post the results. Or if anyone has been able to accomplish this, please, let me know what you used.

I love messing with stuff like this, so I hope it works.

Re: Raymarine Gyro Sensor Upgrade for $25

gaw111,

Thank you for this test proposal.

The fact that components stop being available very quickly is the main problem for a simple cheap Gyro solution. Until recently the IDG5000 was still available in few shops. But this one like previous ones seems now impossible to buy.

Conclusion: if you find a way to integrate two new components, please let me know, and I will add your solution on top of the list, with no doubt sailors will be interested.

Gps EVAL-ADXRS624Z reported as working

Last minute news;

EVAL-ADXRS624Z as been reported as working perfectly by UWE on Gyro pour Raymarine S1/S2/S3 * 25€

It is not the cheapest solution, but at 60 price remains acceptable for most sailors. This being said, any other working solutions especially, especially if cheaper remains very interesting.
