I hadn't heard of this sensor board but it looks pretty nice and the sensor is high quality.
I've been working on a similar project for a while now. It's a USB HID device and can transmit real time altitude data over USB, but it also works as a standalone audio vario logger.
The idea is that if you want to go XC you'd hook it up to your phone, but if you want to fly locally then you could just mount it on your helmet as an audio vario. It's an Open Source project but it's going to be manufactured for sale. We're actually gearing up to do a beta test right now.
I'd love to collaborate on the Android software. I plan on getting the Microvario Pro working with LK-8000 and XC-Soar, but I wanted to build out a simple vario app.
Would love to collaborate
The sensor I found is good but expensive ($41) so if you have ANYTHING cheaper and as good as possible it would be great.
I'm working on the audio part now. Let me know if (how) you want to start - ideas of layout, etc _________________ "Men were not meant to leave the Earth.

I thought it initially with a BT module but the price would have been way above my target of $100 _________________ "Men were not meant to leave the Earth.

Our product price counts the development time of the device and the android app.
And our goal were to made a product with performances as least as good as usual variometers. Our pressure sensor is real 0.1m accuracy and we can provide a very stable value with a fast delay. But these features has its price.
I'm agree that if you make your own, it will be more cheap.
That wasn't an attack, you don't have to defend your price.
Mine can't compare with yours
My sensor resolution is 0.7m so yours is 7 times better!
Also, I'm targeting a price 3 times less than yours (it should be 7 times - but then, I'll give the app for free since that would be only the price of the sensor)
I'm looking for my own niche.
That's Awesome!
Good Luck! _________________ "Men were not meant to leave the Earth. Spend too much time in the clouds and you never want to come back down again. I know skinchangers who've tried hawks, owls, ravens. Even in their own skins, they sit moony, staring up at the bloody blue" -- Hoggon

I just justifed it because I interpreted the previews answer like "this device could be only 100$". Please excuse my suseptibility ;)
In the past I also used this toradex USB sensor with the "openmoko" Linux phone. It was fun and working. I used the tangoGPS app sources and added the vario features on it. Unfortunately, they stop to produce this phone... So we restart from the beginning and made this bluetooth vario.
I also wish you to success with your system that seems already well functional

Regards,
T have been looking at your system since the beggining of the year, before you actually had a sensor to sell. And I have been very interested in trying it out.... but I have to admit that the price also scared me away...
I want to be clear, The main reason for my hesitation to pay 300 USD is that I have never seen one in real life, I know I can buy an old flytec for 300 nearly identical to the one I use in training. So, I was not sure I wanted to be the guinie pig of my local flying club. Also at that time I don't think you had as much info on the specs of the instrument... So I questioned its accuracy. Now I know better. Also I didn't know it would be XCSoar compatible. This makes it more valuable.
However, I do think it would be cool to get in on the ground floor of this technology, even just to be the local fanboy, and try to show the other pilots what our phones can truely do!
Have you thought about a "pilot program" (pun intended) to offer the deveice for a discount now during the start up phase? I believe I would be a good person for this. In fact it was me who started a thread about your vario asking if anyone else had used it yet.. (remember I said you guys were from sweden instead of switzerland) lol (typical american)
I am seriously thinking about buying your device to try in addition to these other system mentioned in this thread. If you had a sale it would probably push me over the edge and I would buy it...................................................................................... If you do, I promise Ill show it to every pilot I meet!
Had some time today and finished the sound module.
Now it's a matter of tweaking...
For the sound i have the following variables that one can set from the preferences screen. I defined those by reading the 6030 manual.
For the more experienced pilots out there (more for the ones who actually fly with a REAL VARIO) please comment for the items below:
- what (vertical speed) should be considered LIFT (and would ignore the bumps)
- what (vertical speed) would mean SINK (I'm actually thinking of setting this from the polar data but until then... )
- I chose the high/low frequencies based on what sounds as musically 'good' for myself. I know the range the human being can hear but I was wondering if there are any 'established' ranges for the sounds.
- STALL is currently alternating SINK_LOW_FEQUENCY/LIFT_LOW_FEQUENCY sounds. Suggestions?
- SINK is continuous sound
- LIFT is alternative SOUND/SILENCE starting from MIN_BEEPS_PER_SECOND for the LIFT_TRESHOLD_SPEED up to MAX_BEEPS_PER_SECOND for the LIFT_MAX_SPEED. Suggestions?
'In Action' (to be read 'in elevator') video will come soon.
Thanks!

Sorry for the long delay in responding,
I think you should try to make as much as possible to be configured by the user.
So the sounds,colors and layout of the whole app should be as customizable as possible. I believe that this is what really gives android based flight instrument the potential to be great! I have heard many pilots make a comment simmiliar to " I really like the layout of my new vario, but I prefer the tones of my old vario"
So, my 2 cents worth would be to make it the users choice....if you can.
Thanks - will do - only I don't want to spend too much time on these features...
Sound ranges are configurable - colors are not (so far )
Now I'll have some time to work on the 'other' device GUI as well...

And then I land and go to call my flying buddies to let them know where I am, oops no battery left!
Steve
This is not a replacement for the real thing.
It could be used on the first solo flights. It's for the weekend pilots, like me. You can take it as a gadget. And if you land and can't use the phone because the battery is dead, use your radio.
Thanks for the positive attitude _________________ "Men were not meant to leave the Earth. Spend too much time in the clouds and you never want to come back down again.
