At a first look at things, I would prefer a 7" Touch-screen, which I think its big enough to let my fingers work on it during flight. I have a fairly full panel in my Libelle: 80mm ASI, altimeter and SDI C4 for starters followed up by 57mm B.40 vario, T&B and radio. Currently me navigation system is LK8000 running on a Medion S3747, held in front of the panel in a fleximount: as its just a 3.5" (88mm) screen, it doesn't hide any instruments. I find its touch screen is useable in flight, but then I don't have big fingers. I was wondering about touch screens because some of the RaspberryPi shops (Pimoroni and ModMyPi) are selling 3.5"/85mm touch screens for around GBP 35. These tend to use I2C bus connections though I did spot one with a USB connector. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

Of course I know the panel-problems, not only with the Libelle. As I am verry much restricted in panel-space in my Banjo, and do do not want to exchange all my 80mm instruments by expensive 57mm instruments, I do look for a smaller and less difficult version. let´s call it a OV-Light. 5" or even 4" touchscreen, without stick-remote, gyro, accellorator and other additional functions. Just a plane Glider-Navigation to replace my old IPAQ with SeeYou running at it. At this moment, I try to get a Light-Specification together with the designer-group, hope this will work. On the other hand, I am just a dumm Electronic-Neandertal (greenhorn), so I have to work out first how to get the PCB´s manufactured and whats the special secret by soldering the SMD´s onto the PCB´s. In the next step, I like to build a Light-Version to get builders-experiance, in order to document those things at my website UL-Segelflug.de, to make the doeing easyer for other builders. Stay tuned at UL-Segelflug.de and watch for progress. Best regards from Germany Klaus |

Stay tuned at UL-Segelflug.de and watch for progress. Best regards from Germany Klaus Hi Martin, I have to revise my Info to you from yesterday, as meantime new findings came up. I did a survey asking all present builders about their experiances and the state of the build at present. All together, inclusive the people from the developing-crew convinced me, that a Light-Version, as I prefered it, would not make any sence. 1. building a full-version will cost somthing like 40-50 EURO more then the light-version. 2. additional time for the build is minor 3. building the full version would include an E-Vario in display as well, so I could take my Borgelt E-Vario out of the panel Taking out the Borgelt will not only reduce weigt of 550 Gramms, but also gives lot of additional space to go for a 7" display. I took out all instruments from my panel, covered it with blank paper and glued shapes of remaining instruments and the 7" screen in original messurements to it. The result: everything fits and the 7" screen looks encouraging. Today I do a new Panel in fibre, so I will proceed the project as explained obove. New panel-layout you can see at UL-Segelflug.de/Blog, where I also described the new findings. I´m sure you could try a similar way, just try it. Touch-screen has also been obandoned, now I ended up with a stick-remote as well. Could be, that I design a small side-panel mounted at the canopy-frame, instead stick-remote.

Yes, I'd agree with that, but if you're going for all electronic varios, you might want to retain something like a 57mm Borgelt B.40 or a Tasmin V1000 as a backup vario. Both can run for about a day from a 9V Duracell battery, so would get you home in the case of a main battery failure. Touch-screen has also been obandoned, now I ended up with a stick-remote as well. OK. I don't want to go that way: take a look a a Libelle's stick next time you're near one and you'll see that, because of the 'automatic' trim mechanics, it would be almost impossible to run wires from that switch set down inside the stick: It was bad enough getting a pair through for the radio's PTT switch, so abandoning the idea of a touch screen option is bad news for me. I heard last night that LK8000 for Linux is getting close to release, so this would make a port of it to a RaspberryPi with a touch screen a more attractive option for me.

There you see, that it also works fine in the Libelle-panel. He also uses a stick-remote with all functions. So it must be possible, to get all cables through the tube of the stick. But if you need informations about that, you better contact Stefan directly via Facebook for advice. Facebook-Link: https://www.facebook.com/45323828144...type=1&theater Regards from Germany Klaus |

I just try to organize a project-group to build a bigger number of computers. Hope it will work. Is there any particular you decided to base the project round a Cubieboard rather than, say, a Beagleboard Black or a RaspberryPi? The new Pi 2B looks quite interesting and there are already smallish touch screens available for it. As a Libelle pilot I prefer small. I happen to have a Raspberry Pi 2 Model B in my hand, and I expect it would be well up to the job if it has sufficient of the right kinds of I/O. It's certainly faster than the A20 Cubieboard 2, though not the A80 Cubieboard 4. As the Raspberry Pi 2 was announced only a week ago I think you can hardly blame the project for not using one! The old model was underpowered when it came out three years ago, and laughably so now. Nice write-up on spec's & pricing....... http://www.electronicproducts.com/Co...a_mere_35.aspx |

I see what he's done. The cable bundle is never inside the metal Z-tube that forms the stick's structure. Instead, the wires run down the outside of the tube but within the body of the much larger carbon moulding. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
