Hi Ross, I'm trying to put together the main board and I'm having trouble finding which capacitor goes in the C7 spot on the back of the board.  I don't see it on your parts list, but I can see something is installed there on your photos.

There is no C7 - there is a C5 (0.1uF, 1206 SMD) on the back of the board but that's it. Where did you see that?

EDIT: I think I know what's happened - I renumbered all the parts after taking the photos, so if you're looking at the JPEGs in my Google Drive folder you see a "C7" on the back of the board, but that's now C5. Go by the parts list and the schematic.

I just soldered up the main board.  As posted above be sure to follow the schematic with special attention to the capacitors.  C5 (parts list/schematic) is soldered in the C7 position on the back of the board and C1 (parts list/schematic) is soldered in the C4 position on the board.  Everything else seems correct.

Note that I updated the parts list spreadsheet to match the Eagle schematic/board. So, when you order the board the part #s will match the parts list.

I think I have made some pretty good progress on the lighting and animation of my 1/650 TOS Enterprise bussards.  Everything is still in the bench test stage, but here is what I have so far. 

I started by using the Adafruit NeoPixel LED Side Light Strip (120 LED per meter).  This side emitting RGB LED strip uses SMD LED's and the appropriate resistors for a 5 volt power input.  I cut this strip into two segments of 19 LED's each, rolled them up and applied hot glue to the back edge of the tape to maintain the shape.  These segments fit nicely into the nacelles.  I probably could have fit 20 or 21 LED's within each nacelle, but I wanted enough open space in the center of the roll to put in a drive shaft for the rotors if I decided to motorize them.  A power lead, ground lead, and data lead are soldered at the end of each strip.  This gives me 19 LED's in each nacelle that are individually addressable so I can control color, brightness, and animation.

The big surprise came when I was playing with the strip test animations (provided by the Adafruit Neopixel library) and the rotors (Paragraphix photoetch) I have on hand.  By using the TheaterChase animation on the strips and adjusting the distance of the rotors from the frosted bussard domes, the shadows of the rotors now appear to rotate within the domes.  Think of how a shadow on a wall moves as you pass by it with a flashlight...same principle.  By soldering the leads to the center end of the roll in one nacelle and outer end of the roll in the other nacelle I now have clockwise and counter clockwise rotation of the TheaterChase animation hence, counter rotating rotor effect.  This is all controlled by one data pin on the Arduino.  I spent some time watching the re-mastered TOS Star Trek with the bench test in front of me.  In addition to adjusting the overall bussard color and animation speed, I changed a couple of the LED's to blue and green within the animation.

I am currently using this lighting with the JT-Graphics Bussard domes, but have also tried it with DLM's Bussard domes.  It looks good on both.  For me this set-up is much simpler, has less weight, is easier fix, and it is dead silent compared to using motors on the rotors. 


I plan to post pictures, Arduino sketch, and hopefully a video of the animation soon.  Does anyone have suggestions on how to film the bussards without them being overexposed?  I have tried night and bright day settings along with different ISO's on my digital camera with little success.

I'm wondering if anyone has used the DC motors from Pololu for the TOS Bussard motors?
https://www.pololu.com/category/60/micro-metal-gearmotors
https://www.pololu.com/category/167/20d-mm-metal-gearmotors

Being way down here in New Zealand, access to a range of motor options just isn't a thing! So anyone who has tried other options for motors, I would be very grateful for your knowledge and experience!

I have tried Pololu motors and they work just fine. In fact, they fit inside the model perfectly. My only concern was the noise - not as bad as the PL kit ones, and very similar to the ones BEM was including in their TOS E lighting kit (not sure what the Tena Controls ones look like). I also tried Sayama motors from Electronic Goldmine, which also fit inside the kit piece.

Thanks for the quick reply, Ross.
I might just look into these, then. Just need to figure out the correct one based on voltage and rpm.

Some of my noise level research:

Average dB Recordings

eBay Short Shaft Motor similar to Pololu (12V, 100 RPM)
- 66 dB

Sayama 12SM-AT3 (12V, 58 RPM, Electronic Goldmine stock #G16300)
- 56 dB

Faulhaber 1524E006S123 (6V)
- 48 dB
- noticeably quieter than the other two; less motor whine
- length & diameter of motor requires reworking the pylon attachment

You want a low RPM motor, no greater than 100 RPM. My board will let you adjust the speed as you like . You can get the same motors Pololu has on eBay.

Thanks for the additional motor info, Ross. I think I am going to make start with a couple of these:
https://www.ebay.com/itm/M20-12V-0-06A-80RPM-5Kg-cm-Electric-Speed-Reducing-DC-Gear-box-Motor/310569474520?epid=1438250557&hash=item484f6219d8:g:qbwAAOSwNa1bbVhk:rk:1:pf:1&frcectupt=true

80 rpm seems about right and I can tune it down in speed (to an ideal 58 rpm?). Pretty sure it's going to be noisy though, but until I get my head around it all I'm not inclined to drop a bunch of cash on expensive motors.

All my parts from Digikey arrived yesterday, so that was cool. Four days from the USA all the way to New Zealand is awesome! The circuit boards from OSH Park won't be here until the second week of March. LEDs from Lighthouse LEDs are here any day now. Exciting!

I'm sure I could have got most things from Ebay for less, but to ensure absolute consistency with your results, I figured it was best to order all the components as specified and not stray too far from the path!

Cheers once again.

Glenn.

I cannot wait to see your progress! Please keep posting here as you go along. I think those motors should be a good place to start.

Where are you in NZ? I spent a few months there back in 1987/88, mostly in Christchurch but I managed to hitchhike all around both islands. Absolutely loved it.

Btw, I only listed the part numbers from DigiKey as a starting point - feel free to source them elsewhere.

The motors you ordered run on 12V so you should switch SW1 to Vin to get that to the motors.

Apologies for the delayed reply, Ross. Im expecting the circuit boards and LEDs to arrive in the next week, so should be able to start assembling soon! I also ordered some 6v 60rpm motors with 55mm shafts on them. Seems long but I figured I could cut them down to length and it might negate the need for bearings to align the shafts with the domes. Time will tell I guess!

I am in Wellington, lived here for about 18 years now.

You may need the longer shafts depending on what you do with the spinning hemispherical dome, but if you do end up cutting down the shaft just be careful to not put too much pressure on it or it could bend the gears and add noise.

I did not see much of Wellington on my drive from the South Island to Auckland via ferry, but the whole country was marvellous.

Woohoo! Shiny!
All of my components have arrived also, minus the LEDs which appear to have vanished into the black hole that is the New Zealand Post Office. Hmm.

At least I can kinda start throwing some solder at things and see what sticks. Trouble is, it will mean putting the other dozen models I've already started on hold while I try to get this thing built!
Or maybe I just do the lights and they can blink away on my desk for six months or so? Hmm...
