Month 5 of 12

On the ends of each UFO for 12 months you'll find a 1/12th piece of a puzzle. At the end of the 12 months they can be combined for a larger image.

Looking forward to your guesses =) #UFOPUZZLE

Filament Samples

All filament samples are at least 20 meters in length (actually more, I increased the length to eat up the extra filament being left behind on the rolls)

Bonus Accessory!

Glue Gloop PLA from 3D Gloop

For the 3rd year now, I teamed up with 3D Gloop for the Christmas accessory. This year it's in the form of the Glue Gloop! I like these squeeze thingers when working with smaller areas to Gloop together as it helps to get the Gloop in just the right spots!

Bonus Project!

Autonomous Hover Sleigh

Parts included in UFO:

  • Arduino Nano w/ Power Cord
  • 1 x SG90 Motor
  • 2 x 8mm x 20mm Drone Motors with Fan Blades
  • 2 x Resistors
  • 2 x Mosfets
  • 9v Battery Clip
  • Power Switch

Alrighty, I apparently have a habit each December project of getting motors that may be under powered. The 2 drone motors are 5v motors, and 53,000 RPM - but after doing the electronics they don't seem to have enough power to lift the hovercraft =( - Either that or I've done something wrong and maybe one of you electronics gurus can help me out.

At any rate - here's the instructions:

Programming the Nano:

1. Download Arduino IDE - > Download Here

2. Plug the USB cable into your PC and the Arduino Nano

3. Under Tools > Board select Arduino Nano

4. Under Tools > Processor select 328p, if that doesn't work, try the 328p (old bootloader). If that also doesn't work, check in the Device Manager that the Nano is actually being recognized and being assigned a COM port. If it's listed under unknown or other devices, try installing the drivers from https://www.ftdichip.com/Drivers/D2XX.htm

5. Under Tools > Port select the USB port your Nano is connected to

6. Download the code below and open the HoverSleigh Arduino File

7. Upload it to the Arduino Nano, after it's done uploading, unplug the USB cable from the Nano

Wiring it all together =P (picture is numbered with the step).

1. - With the flat part of the mosfets facing you, the left pins connect together with the servo, the ground from the 9v and end at the GND pin on the Arduino Nano

2. - The red wires from the drone motors and the servo motor connect to the 5v pin on the Arduino Nano

3. - The right pin of the mosfets connect to the black wires of the drone motors.

4. - Each mosfet separately connects with the resistor from the left pin to the right pin

5. - The orange wire from the servo connects to D4 on the Arduino Nano

6. - The center pin of the mosfet being used for the directional motor connects to D5 on the Arduino Nano

7. - The center pin of the mosfet being used for the lift motor connects to D3 on the Arduino Nano

8. - Cut the red wire coming off the 9v connector, attach the end of the wire from the connector to one connector of the on/off switch. Then the wire you cut off, connect to the other connector of the on/off switch. Then connect the other end to VIN pin on the Arduino Nano

You can then connect a 9v battery to the 9v connector thinger, turn the power switch on and the 2 drone motors should start spinning at full power and the servo motor should swing back and forth between 60 degrees and 130 degrees.

I suspect some of the drone motors are reversed, so putting the fans on them you'll have to feel which direction the wind is blowing before placing them into the fan holders.

The printed parts have 2 fan holders, a spot for the power switch to clip in to and a spot to place the nano with the USB cable out the back. You will need to snip off the 6 pins that are clumped on the end of the Nano opposite of all the other digital and analog pins. The directional fan, you'll need one of the white arms that come with the servo and a screw that comes with the servo to connect the directional fan to the servo. I'll get pics soon - my printer has been down and had to swap out the hotend, so still printing parts >.<

The minimal Sleigh doesn't have the sleigh sides in an attempt to reduce weight. The "HoverPad" I intended to be printed with the flex filament, however I think it'd be too heavy and instead 1/2inch to an inch thick of light foam or possibly a baggie should be used - I'm currently experimenting.

I had a few people ask about how the parts go together, so here's a couple pictures. Also hint - the fan portion in the center I used the Gloop Glue to hold into place =P If you click on the images you can see bigger versions.
