As an aside I should have mentioned that I do have Bob's book and have been a follower on this list for quite some time. My wife thinks I should put a small Jesus like statuette of Bob up on the fireplace . . . te he he. I think I have seen every page on the Aeroelectric web site and have compiled a small book on my own of helpful hints and tips. I was just looking for a school book type of reference to go through the finer details of "acceptable" wiring/electronic installations.

LOL From: "checkn6" Hi Bob, Thanks for the reply. I did manage to find something similar (although I KNOW I have that schematic somewhere!) that will work. Sorry to have been so vague on what I was looking for but I actually have a couple of small projects in mind, one was for a remote(ish) cabin with a 12V Dometic RV type of fridge/freezer and the other was for a portable bi-pap machine while camping but I think I have that sorted as well. Since it is OT I don't want to bother anyone with it. Just hoping to hit someones memory and they would point me to the device that I had seen before.

Unlike the lamp which heats to full temperature in a few hundred milliseconds, the pitot tube takes perhaps 30 seconds to a minute to get within 95% of it's terminal temperature. It only draws 56 amps for a second, 55 amps for the next seconds, etc Bob . . . ________________________________ Message 5 _____________________________________ Time: 07:08:29 AM PST US From: "Robert L.

I'm pleased that you find our collective efforts so useful. You have correctly identified the largest hurdle in the sharing of a practical technology. There's the study of ingredients that go into recipes for success, then a recitation of recipes that have benefited from critical review and practice and finally, the processes by which those recipes are brought into useful fruition.

I got a copy of chapter 11 and set out to study the validity of it's latest version. 3-4 days later, my review along with reviews of many other EAA members was submitted to the authors. Dead silence. I think it was perhaps 18 months later that the latest and greatest AC43-13 was published. It was much better but was still sprinkled with toe stubbers in both practice and technology.

In the above paragraph > replace Book w/ Website - and I agree whole heartedly - > a visual library would speak volumes without a word. Ahh . . . but of course. That's what I meant. I sorta started this effort when I built the website. I have an archive of photos at: http://tinyurl.com/b5o58uq but it's really clumsy to access. You have to look at every picture one at a time to see if it's of interest. There should be an html thumbnail page, perhaps 4 columns wide that shows each picture in brief. Clicking the image of interest would get the reader a blow up. I've mulled over a software program that would automatically generate the .html from a text list of jpg file names. There might also be a click-to-read link for a description of the photo contents. The text files would be read by the search engines and cataloged. There might already be a utility for generating such a page. Do any of you HTML gurus know of one? This might offer a mechanism for accepting photos from virtually anyone showing the mechanics of a host of tasks and getting them published with a minimum of time. Bob . . . ________________________________ Message 8 _____________________________________ Time: 08:10:39 PM PST US Subject: AeroElectric-List: Re: OT but electron related, I hate it when that happens! From: William Curtis Chris, et al, This may be what you were looking for. Below are links to the 12 volt power system I have running throughout my home. Where I live, It seem every time a tree falls, it takes out a power line and there are frequent black and brown-outs that have ruined a few of my home network devices. This is what led me to put this system together but I also use it to power the electrical system of the RV-10 and charge its batteries. The system works so well and power disruptions were so frequent, that I have expanded it and installed 5.5 x 2.1 mm 12v power connectorsin each room of the house for 12 volt lighting and accessories. The main fuse block in the basement feeds to additional fuse blocks on the main floor and in the attic. These upper level fuse block feed rooms and devices. The system powers ALL my home network (routers, NAS, WiFi controllers, etc), home phones, cell phone chargers and other accessories. For the devices that require other than 12 volts, such as my cable modem that requires 6 volts, I was able to get inexpensive DC Converter 12V Step down to 9V and DC Converter12V Step down to 6Vfrom eBay. See links below. During a black or brown-out, the system immediately switches over to battery power as the relay cuts power to the power supplyand disengages the power supply from the system. This is the function of the AC relay. You do not want the power supply to be on line to the battery when it is not producing power. Otherwise it will cause additional drain on the system and may be damaged. When power is restored, the relay is engaged providing power to the system and recharging the U1 battery. No expensive diode or voltage drop concerns. With the single generic U1 battery, all my devices will remain powered for about 4 hours following a power disruption. When I engage the connection to the Odyssey battery in the RV-10, power capacity increases to about 10 hours. I=92ve since determined that my cable Internet provider battery backup is good for only about 8 hours so two U1 should be sufficient. Late r I plan to integrate a 100 watt solar panel to charge the battery so that all my home network devices will be =93off the grid.=94 Hope this helps.

Not sure what OS your website is running, but I wrote a very simple Bourne shell script to do this on my Linux based web server. The script takes an argument of a list of jpg filenames (or just a wildcard, like "*.jpg" if you want to include all jpg files in a directory). It reads the list, creates a thumbnail version of the jpg using the "convert" program (part of the ImageMagick open source suite), and creates a simple index.html file consisting of the thumbnails, and clicking on the thumbnails brings up the original full size image. It is about as basic and non-fancy as you can get, but you are welcome to use it if it might be helpful to you. Should be easy enough to modify to create whatever formatting you wish in the html. File is attached that includes the code. -Dj -- Dj Merrill - N1JOV Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Glastar Flyer N866RH - http://deej.net/glastar/ ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
