 Posted: Fri Sep 14, 2018 1:40 am Post subject: IVO current limiter project |
 |
|
What was the final status of this current limiter project?I've downloaded all the info from the Aeroelectric site but it is still labeled as under development.
I'd like to build one, but before I order a few boards from pcbExpress, I just wanted to know if the project is completed as it stands now?
 The components are cheap but the board is expensive and I'll end up with 3 of them, so is there anyone else who would like a board?
 It looks like I'll also have to invest in a PICkit 1 flash starter kit. These are no longer made as they are now up to version 3, but they can still be bought on eBay. Or is there anyone who was previously involved in this project that can program a chip for me?
Thanks
Todd Bartrim

The builder who used this project on his plane posted that it worked very well.

I have purchased PCB boards from elecrow.com at low prices compared to local PCB houses. The disadvantage is that it takes up a month to get the boards.
A low cost option is to use a magnetic reed switch instead of the circuit board. Wrap a reed switch with several turns of wire. Put that wire in series with the motor. When the motor current is high, the reed switch will close and turn on an indicator light.

I'm a bit confused about the status of this project.
I seem to recall having laid out boards, stuffing
a prototype and handing the proof-of-concept board
off to someone to be programmed.

[img]cid:7.1.0.9.0.20180917170551.06667428(at)aeroelectric.com.1[/img]
I dug around here looking for the project-bin but could not
immediately put my hands on it.
Did this fall down a crack somewhere . . . and is the crack
in my shop?

Hi Bob;Â I'm hoping that the code was complete and boards were proven to be correct as I've put in an order for a board (minimum 3 and it appears that each board had 2 designed into it, so 6 boards) and ordered enough components from Digi-Key to populate all 6.Â
I've also ordered a PICkit3 programmer to program the PIC.
 First I ordered the PICkit1 from eBay as the notes indicated that was used as the programmer then I immediately realized that it was an obsolete programmer from the 90's but seller wouldn't cancel the order, so I still ordered the new PICkit3 and will use the other one as a paperweight to remind me why Amazon is better than eBay.
 Anyways, I expect boards, components and programmer to be here within a week and we'll see how it all comes together.
I'd be happy to split up the rest of the boards and components (programmed with the code of coarse) for anyone who wants one.

Was this an extension of the approach
I published or a parallel effort?
I was thinking I'd handed off the schematic,
BOM and a quantity of boards off for
further development but that was too
many projects ago and I've lost track
of the details.

Hi Bob;Â This is the project that was ongoing for several years on this list but abruptly ended in July 2017. I was following the discussion with interest, but other responsibilities at the time left me unable to get involved.Â
As I recently returned to flight again, I quickly remembered why I thought this was a much needed improvement for the IVO prop. So I read through the archives and studied the material you have posted at http://www.aeroelectric.com/Catalog/AEC/9023/
I did post a message here a few days back inquiring about the status of the project, before I ordered the parts to build one (or 6), so I'm now somewhat financially committed to at least trying to stand on your shoulders and complete this project. The info posted at the link on your site seems to be complete and the last posting about it didn't declare it to be successfully finished but that Beta-testing was about to begin, then nothing further.
So I guess I'm going to be a beta-tester?

Got the board stuffed.

I need to get my pic programmer up and running
for a couple other programs. I'll pop a 9023 chip
and see how critter works.

Bob and all,
Did we ever finish this project? The message attached below was the last one I heard about it. I don't know if that means it worked, that it didn't work and we gave up, or everyone just lost interest.
I don't have an IVO prop, so I don't need the limiter. I just wondered if the software that I contributed needs any additional refinement.

If there was a limiter produced I didn't see it.

Okay guys . . . looks like I dropped the ball on this
one. I'll hide behind the 'too many projects' phenomenon.
Got another grand-kid living with us for a year to
try alternatives to Wichita schools . . . etc. But
that's not an excuse. I'll dig around and get that
package together.
I know Paul had sent me some POC software and I
don't recall having loaded it into a chip. We'll
get that pot back on a front burner today.
