    Howdy List! Regarding previous posts about my problems with epanelbuilder: Bill VonDane has been in touch and it appears epanelbuilder is too much for my slo dial-up connection to handle But much to his credit he is working to make it more accessible for those of us still in the 20th century. It really looks like a useful tool, but just not so much for those of us who prefer putting ga$ in our planes instead of the pockets of the Internet mogul$. (sigh) Maybe one day when I get rich like everybody else, I'll be able to get all that advertising at breathtaking speed! 8-) No ill-will intended for epanel, but at least now I know what the problem is- my penny pinching! 8-( Mark Phillips - do not archive

    --> AeroElectric-List message posted by: "Jim Butcher" <europa@triton.net> Dick, Thanks for your comments. I agree the MSI PVC housing is a problem. I was thinking about disassembling the sensor and machining a brass housing. The nice thing about the MSI is that it already has an amplifier so the output voltage can go directly into my BMA EFIS. I think the materials in the Honeywell are OK for gasoline. I know several Europa drivers who have had this installed for over two years with no problems. I'm still trying to decide which way to go.

    Mark, I have a DSL line, so I didn't have the same difficulties you did. However, the site is a little difficult to use. First, it really doesn't work at all until you pay (minimum is $40 for 3 months). This turns on most of the functionality, including the ability to save your project so that you can see it and work on it again, or print it out. Navigating around the site is a bit odd. Things don't always work in the way a MS Windows user would expect. Second, there are a few common items missing - for example, I can't find any type of Hobbs meter in the libraries. Also, most of the items I am planning to use in my panel are missing information (electrical load, weight, cost, etc), so the summary pages are pretty much useless. Nevertheless, it's a pretty quick way to do several conceptual layouts of an instrument panel when you are trying to decide how to arrange things. Just remember to "SAVE" before printing or closing! Keith Hallsten Planning a Velocity XL panel Howdy all- Has anyone had any success using this website: http://www.epanelbuilder.com/ I've registered, downloaded the required Macromedia app, supposedly started a project, couldn't get any instruments to show in the library (after struggling for 15 minutes to get a panel template to show) and then couldn't open that project next time I tried, and generally run into more problems than any app (out of hundreds- this stuff is NOT new to me!) I've ever tried to use before. Then tried to get assistance, been issued "tickets" (what ever happened to customer support via e-mail, fer chrissake!!) and am genuinely frustrated and annoyed after over 3 hours for 2 days of trying to accomplish anything. Must not be holding my left foot in the correct position or the moon is out of phase. Anyone else with horror/success stories with this? Suggestions for alternatives welcome- maybe I'll just go back to AutoCAD and my previous excellent panel cutting service.... Mark Phillips N51PW do not archive

    Subject: 28 V dynamo question
    --> AeroElectric-List message posted by: Gilles Thesee <Gilles.Thesee@ac-grenoble.fr> Hi Bob and all, A buddy is asking about the Scintilla 28 V 300 W dynamo on his LOM engine. Does anyone know of a suitable voltage regulator at a reasonable price ? He says the one on the Moravia website is much too expensive. Some builders have suggested connecting the dynamo to the battery direct via a diode, and devise a simple regulator with a transistor and some simple components. I recall intricate devices with vibrating coils, shunt and series coils, cutout adjustment, etc. Have things become so simple today ? Any input appreciated, Regards, Gilles Thesee Grenoble, France http://contrails.free.fr

    Do Not Archive Mark, How did the site work for you in demo mode, i.e. before you paid your $39? I've been using the demo mode to layout my panel for fun, until I'm ready to committ the $$ and time to make a hardware copy, and it seems to work well. The "ticket" system of communication seems like a solution looking for a problem and is cumbersome. But I found the guy who runs the site (Bill Dane, if memory serves) is responsive, and obviously overworked. The panel I'm using (Glasair FutureVision) was not in the inventory of templates and I emailed the file from Panel Planner to him. It was up on EPanel's site within a day or two and needed only minor tweaks to get to the right scale, which EPanel accomplished quickly. if EPB worked for you in demo mode, despite limited features, and it stumbles after you subscribed, then I would want to hear some answers from Bill Dane. Thanks for the heads-up, John

The last data I had on the LOM power generation of choice showed a classic, wound field generator wired per Figure Z-18 An electro-mechanical regulator for this generator would look something like this: http://www.aeroelectric.com/Pictures/Regulators/GenReg_2A.jpg There ARE solid state replacements for generators but these are much more difficult to build than for alternators. Generator regulators need reverse current cutout relay or diode, current sense and limiting in addition to the voltage regulating duties. See chapter 3. This cannot be done with simple circuitry. Further, the generators are generally slower in their response to changes in applied field voltage. Regulators tend to be more specific to the type of generator while alternator regulators generally work with a wide range of alternator sizes and brands. Short answer is that one can PROBABLY craft a suitable regulator from pieces and parts but the $time$ invested would most certainly exceed the $time$ required to purchase the off-the-shelf part. I doubt that any of my clients of past years would even consider bringing a modern generator regulator to the market. The market is too narrow and expenses are breathtaking.

    --> AeroElectric-List message posted by: "Brinker" <brinker@cox-internet.com> Bill has been very helpful for me and has added items as I have requested them. The ticket system worked very well for me. Though sometimes it may be a day or so in getting anwsers. No big deal to me I'm not in a hurry. Although beware, the accual size of my panel (Aerocomp C6) vs e-panel was not exactly to scale as I found out. The width and height seemed to jibe I think it was the rounded contours that threw me off. Bill offered to fix that too but I did'nt think it worth the effort since the program is mainly for preliminary design. And very good it is. I changed my accual layout after I saw layed out in the real world as I'm sure most do.

It's really limited the time I can spend doing fun things. Should be over this weekend. I don't know of any commercial devices. I have a kind of generic etched circuit board that carries a little 8-pin micro-controller and some general purpose input-output pins. My program guy could teach a chip to do a tach signal interpretation and close a circuit when the signal stays above 1500 rpm for 30 seconds. There are probably others on the List who could do this too. I'm wondering how much interest there would be for such a device. It would take quite a bit of high-talent time for a one-of-a-kind project.

In rv's the only use I can think of is to turn on/off avionics that are normally switched by sqat switches or the like in the certified world. With the decreased price of tcad units there may be more demand soon?? I am not in a rush, but, I am interested in an electronic version of this switch. Please let me know if you get a chance to look at this a little deeper. Thanks.

    Subject: Panasonic LC-RD1217P and Van's Battery Box Misfit
    From: James H Nelson <rv9jim@juno.com>
    Hi Bob, I took a few pix of the mod to the battery box. This should give you the idea on how it goes together. My first attempt tried to get the whole "other" battery into the box. However, the Panasonic does not have the little ridge around the top which holds the battery about 1/4" up from the bottom. I will file that ridge off the generic battery so it will go all the way to the bottom. Then again, I might put a spacer in the bottom to take up that space. I'm not in favor of trimming the little flange around the top of the "other" battery. It seems to be where the top and bottom come together. What is your thought on trimming or spacing for that little protrusion? Jim Nelson

    --> AeroElectric-List message posted by: <rparigor@suffolk.lib.ny.us> I had a chart a while back (can't find) that showed in detail what could be put together and what not to put together if you wanted to have a good chance at not creating dissimilar metal corrosion. Anyone have one or know where to get one? Ron Parigoris

    Subject: Power and audio input jacks
    --> AeroElectric-List message posted by: "DEAN PSIROPOULOS" <dean.psiropoulos@verizon.net> I'm taking a poll: What it the most popular power jack used in portable electronics today? I am planning on putting two power outlets in, one is the cigarette lighter plug. I thought I'd use one of the smaller common power jacks for a second source as well. Good idea or should I just put in another cigarette lighter plug? Audio input jacks for my stereo audio panel...again what is the most popular style of stereo plug used in portable electronics today? I'm guessing it's the mini plug like that used on computer speakers but not sure. Dean Psiropoulos RV-6A N197DM Still a few holes needed in panel.

    --> AeroElectric-List message posted by: Gerry Holland <gholland@gemini-resourcing.com> Dean Hi! From UK I have standard Cigarette Lighter type 12V Auxiliary. May put another in or with care use dual input adapter occasionally. The people I know who have fitted the very neat 12V socket have always had to make up an adapter to the 12V auxiliary type! I've limited my in-line fuse to 3 Amps. For audio into Intercom I using the mini plug and socket. Works really well into my PS 500. Regards Gerry G-FIZY
