I was directing my comment to Jurgen - the poster who complained about a gazillion pages of gibberish and in so doing included the gazillion pages of gibberish for the rest of us to experience. I get the list via the once daily digest. When someone replies to a digest email, the entire content of the that 24 hours of email are included in that reply. And then when the list subscribers get their next digest email they have to scroll through an entire 24 hours of list postings in the middle of the current digest of emails. Jurgens post includes an example of how the digest version of the list arrives in subscribers' mail box.

But that's easily done in EEPROM values. Paul On 7/10/2017 10:11 PM, Robert L. Nuckolls, III wrote: > I proofed the ecb layout I posted. I'll get some > made.

Fisher" Certainly. Bob, could you please add the IVO Prop controller software to your site with the rest of the files? It's currently in our Dropbox share. Please be kind on your comments on the code - I haven't tried to clean it up to make it presentable - it's still at version 0.03, so I may still do quite a bit of tweaking before we declare v1.0. But I am interested in anything you see that we could improve on. Thanks! Paul On 7/11/2017 5:03 PM, Alec Myers wrote: > > can you post your code for review? > > On Jul 11, 2017, at 17:50, Paul A.

Sorry for the delay . . . was in Wichita putting the finishing touches on a staircase to my sister's deck. Paul's software offering can be found at: http://tinyurl.com/yby3waw6 You guys might be thinking about how you'd like to configure the 'elegant' package. The ECB I've crafted will lend itself to either an open- to-the-sky style of installation, like our old AEC9005 . . . Emacs! of course, this can be put into some form of enclosure with the connector extending through the wall. There's a kinda cute extruded aluminum enclosure offered from several sites on the 'net . . . Emacs! The final configuration could be converted to surface mount components. Connections brought out on flying leads through a grommet. The advantages for thru-hole components is that more people might be encouraged to take on the project. Anyone spotted another option?

I guess with the through-hole PCB layout done and ordered, there's probably little point in me continuing my effort to do it here. I'll lay down my pencil unless there's another way I can assist. If it's decided to pursue a surface mount version, I'd be happy to work on that. Just say the word... Cheers, Eric ________________________________ Message 10 ____________________________________ Time: 08:04:58 PM PST US From: Jeff Point Subject: AeroElectric-List: Troubleshooting 200G/ Z-17 All, The good news from today is that I successfully ran my freshly overhauled O-200 today in preparation for a FAA inspection in a few weeks. The bad news is that I am getting no alternator output at all. The alternator is a B&C 200G PM dynamo, wired per Z-17 (no master contactor.) Running the engine between idle and 1800 RPM saw no change in bus voltage, which stayed at the same 13.1V as it did with the engine not running. Troubleshooting so far- besides checking all wiring connections, I verified that the OV relay is working and that I wired it correctly. I verified that the alternator's raw output was as expected (15-25VAC, increasing with speed.) I measured voltage at the capacitor (just downstream of the regulator) and it was the same 13.1 and did not vary with speed. Disconnecting the regulator I verified that there is zero volts coming out of the regulator, although I understand from the troubleshooting documents that it must have bus voltage applied in order to output, so I'm thinking this doesn't mean much. Is this as simple as a bad regulator? I'm going to call B & C first thing tomorrow but I thought I'd check here first.

The board I have is about 2x the area that would be required for SM components . . . and if I were tooling up to build quantities, I'd go SM. But if we're wanting to maximize penetration into the DIY community, TH is probably better. Once the hardware and software are successfully married, an SM version in the smaller extruded aluminum enclosure might encourage someone to build up small quantities for sale . . . to be sure, the plug-n-play community is larger than the DIY community. B&C might be intreseted in adding it to their stable of products . . . let's see how the project matures.

The boards I mentioned are bare boards which I will make available to individuals who will be the beta-testers . . . they'll have to acquire parts and assemble them. At the moment, I have no plans to produce them here but somebody on the List might be willing to help you out.

Yes . . . was your alternator disconnect relay closing when you moved the switch to ALT+BAT postion?
