From: rparigor@suffolk.lib.ny.us Hi Group I received a request for cost of shipping 3 kits: USPS Large Flat Rate Box fits 3 kits, cost $15.45 anywhere in the continental US USPS Medium Flat Rate Box fits 2 kits, cost $11.35 For sure 1 kit will fit in a Medium Flat Rate Box for $11.35, but if close to New York 11754 it may be worth it to go Parcel Post. I gave weight and dimensions of the battery, add some bulk and another 2 pounds for the other stuff, you can look up on USPS site and figure which way you would want one to ship. BTW They were all top off charged as of 2 weeks ago (not a trivial job!). Also I will provide a schematic for hooking up the charge control circuit, not very difficult, but it has three outputs, one for charging the battery and two more, one went to the 15 amp cigarette receptacle and the other to the volt meter. This is really a great deal, I just don't have the time to put together into a fully assembled pack that could be sold pretty easy for 30 or 35$. There are 500 kits at the moment, in a few weeks I will actively look for a new home for them so if you are on the fence, speak now. Here's where the rest of the jump start packs went: http://www.youtube.com/watch?v=9YaKOkcDM_s Ron Parigoris "rparigoris" > > > Hi Group > > I have quite a few brand new sets of components from a Jump Start Battery: > https://skydrive.live.com/redir.aspx?cid=550fc20dbddb521d&resid=550FC20DBDDB521D!413&parid=550FC20DBDDB521D!408&authkey=!ADA-L-1AURQ0PJU > > We gutted the brand new jump start packs because we needed the case, volt > meter, flashlight and receptacles. > > The set consists of one 9lb AGM sealed Lead Acid Battery, a 500mA constant > current charger with line cord (UL approved), 1 set of jumper cables a > little shy of 2 feet long, the charger control board that turns charging > off at ~ 14.1 volts, also a DC cord that you can charge from a 12 VDC > source (Red LED turns off when charging is complete) and a 15 amp > resettable fuse that was attached to a cigarette adapter. > > I'm looking for $10 each plus shipping.

If the pins are not staying in the shell when reinserted, it may be due to the fact that the locking tab is not engaging the shell. When you use the tool to remove the pin, you are deforming the locking tab into the pin and it won't grab the shell. After pin removal it is essential to pry the tab out, gently, only enough so it will lock in place when reused.

Taking a quick look at the options for text to be included in software code I found this FAQ from Creative Commons describing the use of the CC0 option as a recommended approach for putting new works into the public domain. http://wiki.creativecommons.org/CC0_FAQ It would appear that the CC0 approach could be used for all of the materials associated with this project. Until there is a standard approach for the project I plan to use the info above for any software I send out.

Until there is a standard >approach for the project I plan to use the info above for any software >I send out. Let us take care that we don't make this more complex than it needs to be. No matter what process, intent or forum we use to share these efforts, the ONLY reason to put a fortress around all or any part of it is if one intends to defend the fort. Somebody once suggested during an Electro-Mech engineering coordination meeting that we seek a patent on some new gizmo we were working on. The boss said he didn't have time for that. He opined that having a patent not only took time to acquire it, it's was not really useful unless you were committed to defend it too. He preferred to get there first, market it best and obsolete it ourselves with the next generation. Being good at what you do trumps the efforts of the lazy who would dishonorably exploit the creativity of others. While browsing through the various links to processes and procedures banners under which we might march, I was reminded of the Great ISO9000 certification task we took on at Beech. Sweat, blood and tears were shed to produce a wall of P&P manuals that we were all supposed to be familiar with and use for guidance on how to do our work. They cost our company $millions$ but gave us the 'privilege' of putting that little "ISO9000" sticker on the sign out front. I looked through a couple of articles that purported to be helpful to me in my work, closed the book, put it back on the shelf and never looked at it again. When it was known that the ISO Inquisitors were going to visit, I had things to do over in the EMC lab that day. Actually, it was pretty easy for the engineers. The Inquisitor would ask, "What are you doing?" One would answer, "Just what that guy in the corner office told me to do." "What policies and procedures are you bound by?" "Not a one." "Say what?" "Yeah, there is no policy and procedure up on that wall for organizing the creative thought process." That usually stopped the inquisition . . . I just preferred not to deal with them. I recall some time-study guys sitting on stools with clip-boards and stop-watches at Cessna back in '68. They were there for a couple of days and then left. Hear later that they were unable to tell what we were doing while staring out the window, "Thinking about how to solve a problem, or deciding what beer to pick up on the way home." The point being that if we do some good things, publish the works on aerolectric.com and then choose not to defend or complain about how any of that work is exploited, then the process by which we choose to publish is moot. Just as ISO didn't help any of us be better engineers, the policies and procedures by which we publish our own versions of 'open source' won't make us better teachers. Maybe we need to coin our own phrase to describe the process that doesn't cause folks to run to the policies and procedures archives to see what motes and gates have been constructed around what we do. There used to be a rather larger "free university" project in Wichita. Staffed by individuals that ran the gamut from Phd to skilled practitioner. Their goals were simple, "I've got something to share. Come sit for awhile and let's talk." I think it sufficient to make these projects a simple extension of what has been done here on this List for over a decade. Help folks understand and broaden their horizons.

I don't know what that text should say and the most clear guidance I find is that provided in the Creative Commons CC0 FAQ... If another version of text is provided for the project I will readily make the switch... Anyway, I finished the initial spin on the code and will do some testing on a breadboard setup before sending it along. Still targeting later this week to send it out.

I'll plan on sending you a stuffed board with a socket for the PIC. Also some PicChips. Do you have a handy source for 12VDC power? Bob . . . ________________________________ Message 9 _____________________________________ Time: 02:21:14 PM PST US From: "B. Ray Griffith" Subject: AeroElectric-List: Poor Man's Battery tester I built the poor mans tester Figure 2-4 in AeroElectric Connection. My only modification was I have three bulbs in parallel to simulate the load I have on the battery that I estimate at 11amps to run my fuel pump, ECU, and Ignition. The problem is when I connect the test to the battery and have all three bulbs on the tester kicks off at 13 volts with one bulb it kicks off about 10.5 Volts and with 2 bulbs it kicks off at 12 volts. I have rebuilt the unit with new 10v Zener and I get the same results. Does anyone have any suggestions what I have done wrong is do I need to change the resistor size between the load (bulbs)?

Do you have the >capability to flash the micro or should I send along some chips >with the code installed? My programmer is in Wichita. I can wait until you're satisfied with the program then you can send me a couple of chips. The mini-board order yields 6 proof of concept boards. I'll stuff an couple of extra wig-wag boards. As soon as we're both happy with the performance, I'll set up a DIY page that will include the projects already on the website along with our latest efforts. Then we can see how many List members want to bake their own cake . . . or would like to have one baked for them.

Thanks, Ray Ray, I thought I had responded to this query. I think I was in OKC. In any case, there's something fishy about the shift in shut down voltages you cited. Irrespective of how many load bulbs are on the tester, it should drop out at some voltage below 11 volts. When a battery drops below 10.5 volts, it's 98% used up. The description of your experiments don't prompt any thoughts as to what's happening. If you'll mail your electronics assembly to me I'd be pleased to troubleshoot it.
