I've got code written for the PIC as well. I may need to tweak the
voltage and time parameters to get exactly 0.5v and 0.5s when we get
down to the actual circuit. But that's easily done in EEPROM values.

can you post your code for review?

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

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 . . .
[img]cid:7.1.0.9.0.20170711182114.06b813d8(at)aeroelectric.com.0[/img]
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 . . .
[img]cid:7.1.0.9.0.20170711182114.06b813d8(at)aeroelectric.com.1[/img]
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?

Wow -- I went to work for a two-day trip and you guys have the project all but finished!
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

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.

Emil, at the moment, this is a spontaneously
organized cooperation to develop the product.
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.

The boards didn't make it here yestereday . . . flight
delay . . . will be here Monday.
How do you guys want to disposition the 5 extra boards?
I'll keep one to play with. If as many as five others
want to build one, it sorta makes sense that one
person in the build group buy parts and split
up into kits.
Saves on postage, procurement $time$ and perhaps
increased opportunity for quantity breaks.

either crimp or solder-cup connectors. Also missing
is a callout for a D15H hood. The builder will need
6-32 hardware to fasten the assembly down to the

A LED travel limit annunciator is also missing from

Unless the builder has programming capability for
the PIC chip, I'll suggest the chip not be ordered
from Digikey rather from someone in the project group
with programming tools.
I think the mechanical aspects of the data package are
now complete. I'll assemble one here as well so we can
beta-test software and compare notes.

parts to stuff one but found a couple
of shortages. On order for delivery by
priority mail . . .

Bob and all,
I've got 7 of the PIC chips in inventory today, so I can program them and send them to people who want to do some beta testing. Or I could send them all to whomever is going to be putting the kits together. I would suggest we let Bob assemble one of the boards and do a quick check of the software before I program the rest of the chips.
