Teeces Lighting Part II
#1
So, my assembly was going swimmingly until I got to the PSIs. You can see that only one row of lights was getting lit instead of the whole bottom half.  I checked and rechecked solders, wiring, and IC seating ( I actually had one chip not fully socketed at one point).  No luck.  So I went to the Ardiuno code and found a bug.  The string constant that defined the light pattern was wrong. Something like  00001000, instead of 00001111.  Once I changed it it worked... yay!  I let Curious Marc know and now the code on his site is correct.

So, I had all of these servos to test and I whipped up a quick servo test tray.  You can find it here on thingiverse.com.  I printed two of them to handle all of the dome servos while I was testing and troubleshooting.  It holds a standard SG-90 servo.

The next issue was mounting the servos into the dome.  Thanks to Mr.Baddeley for supplying the Fusion 360 files for the dome (and body).  I used them for reference and build some servo hinge mounts.  I needed two flavors.  One for most spots and one for the spot next to the interior seam.  That one needed a special mount that was offset so it would fit in the small space.  Both are available on thingiverse.com. They each link to the other, so you can find both with the link I provided.

You can find mounts for the Wifi, Pololu voltage regulator and a generic circuit board I used for my 5V power bus on my thingiverse site also.

Here is a shot of the dome pie hinge servo hinges installed.

Initial wiring and servo setup.  I know it's a rats nest.  I bought a crimper and wires to make custom wiring bundles.  Before R2 goes "live" I will tidy up the wiring.  This shot shows where I mounted the Marcdiuno boards, the 5V power bus, the wifi, voltage regulator and all of the panel servos.



Here is the initial test.  I need to tweak some of the panels.  But overall, I am pretty happy with the results.

Nice work, it looks great.

Wish I was up to that stage.... :-)

Eebel... Been reading through all your posts and using several of your designs...what do you have your Marcduinos mounted to.. Hard to tell but looks like one of the servo mounts..And what all are using the 5v bus for? Thanks in advance

Yeah, I just mounted the marcduino to the bottom of a couple of my earlier servo mounts. But, hey can go anywhere. I got the Marcduinos from Mowee and he supplied the mounting bracket.  I believe the stl for that is on Curiousmarc's site.    Each marcduino needs to be powered directly with 5v.  No daisy chaining or you will get brown-outs and things will be wonky.  So I built a makeshift header-pin bus by soldering the backs together and supplying the output of my 5v regulator to that bus.  Then just plug everything that uses 5v in the dome into that bus.

I got a couple of Mowee Marcduinos as well, I like the way those mount in your dome. Have to put together a bus for mine... Good idea. Thanks again

Eebel,

Are you powering the 10 pie/panel servos thru the header-pin bus you created or are they being powered thru the marcduino?

Lowlight.

Lowlight.

The power for the servos comes from the Marcduinos.  However, both Marcduinos and the Arduino get their power directly from the five volt bus.  I initially had the power daisy-chained from device to device.  However, this caused brown outs if too many things were needing power at once.
