Just an ideea,i saw the "more than impressive" work of Hari ( www.pixelproc.net) ,one of his varios ( http://pixelproc.net/pic24hj12vario.html ) can be used as ""vario co-processor" in a flight instrument. It will respond to commands on the SPI bus to set the sinktone and climbtone thresholds, turn the audio on and off, or return data such as altitude, temperature, climbrate etc."
There is plenty of room inside a Mio m400 for such a small vario.
Beat that {insert name of big vario producer}! |

No you won't beat any less than decent real vario with that one.
Problematics beyond vario sounds are about integration of values, sampling at 5 to 10hz, and rendering the result to people. Hardware is not a problem and it is cheap. |

Of course ,Coolwind.
I was reffering to the combination vario/lk8000/mio + my frustration regarding my recent purchase of an expensive white plastic chirping thing  . |

You will be amazed to know what Vladimir from Gliding Tools is working on...

Just wondering if Vladamir of Gliding tools could provide an update on this and expected date it would be available. Would be very interested in purchasing one.
I'm sure other PG's would be also.

Something like this, perhaps? 
But running on LK8000 software? 
I can dream a little bit, right?

I would definitely would go for this particular design if that kind od stuff were up to me:
1.- Lot on battery energy saving from keeping a smaller light matrix up all the time.
2.- Even the best color display against the sun glare canīt hold up like BW LCD, I know this very well; I fly with an iPaq 310 and a Compeo+.
3.- Some info displayed on a BW LCD can be read faster and easier, thatīs why even LK8000 have a black or white background for some text.
4.- Form factor helps, somehow this design helps you a lot to find relevant info on less than a second just exactly like car gauges when driving, it's never the same on a full display, that's actually why they don't put full size color displays on cars. |

Hari confirmed that is possible for his vario to send baro ( and beeping in the same time :)) data ,i spent a few nights trying to understand the code ,not succesfull ,but i keep learning and trying .
btw that deck is almost done ( http://www.aerowear.nl/page0/page0.html ) ,just need some guy to design the hardware and create the software.

The problem is, that you will need PDA with USB Host capability (able to connect USB devices) to connect that sensor. Such PDAs are really rare. |

Guys,
I'm new to the forum, but reading it already for some time now, I run LK8000 and some chinese hardware with wince5.0, worked flawlessly from the beginning. No hacking required since windows is available by default. What I don't have, is an rs232 input nor barometer.
I have 2 questions: after lengthy searches on the internet, I haven't found an affordable variometer/barometer with rs232 output. I have seen the design of pixelproc and others, but frankly, they are a little too complicated to assemble for me, including the chip programming and stuff...is there any such solution available and affordable of the shelf ?
Secondly: is it actually a serious advantage to fly LK8000 with barometer input for the calculation of thermals and/or glide ratio ? or is it nor really needed ?
regs,
lode |

Try to get a Flymaster F1 used (it has RS232 and BT)...
I was using F1 and a PDA and I switch to a MIO 400 with no regrets :) I still have a good vario helping me on my lifts. |

Thx Sergio, I know, but that Flymaster is a little expensive to my taste...I already own a decent vario, if a little old, my brauniger IQ basic does a good job, even with a broken screen :-/.
I think I will try to make a barometer myself, I think anyways that a cheap barometer would make a nice complement to LK8000 ! (not as a vario, but purely as an exact altitude reference)
Paolo, what should be the exact syntax of those NMEA phrases ? looking for a barometer-altitude only phrase; LK8000 should continue using the internal GPS.
What frequency you reckon would be appropriate ? 2 Hz, 4 Hz ?
If ever I manage to make something for a decent price that actually works, I will of course share ;-).
regs,
Lode |
