Magpie Sci-Goggles

2022-04-25 | By Jorvon Moss

Let’s walk through the build process for my Magpie Sci Goggles. ‎

The items you will need are: ‎ ‎

Goggles (ArcOne G-FLY-A1101 The Fly Safety Goggles) ‎
3D printer (I use a Creality Cr-10 3D printer) ‎
PLA filament (ANY COLOR YOU WANT)
‎‎E6000 237032 Craft Adhesive, 2 fl oz Clear
‎Adafruit Trinket - Mini Microcontroller ‎
PowerBoost 1000 Charger
‎Lithium-Ion Polymer Battery‎
2x-Micro servos ‎
Soldering Iron
‎Jumper Wires

Code and STL files can be downloaded here. ‎

Step 1: Print Parts ‎‎

Printing the parts should not be too difficult if you have experience with a 3D printer or you can use a ‎‎3D printing service. I have sized everything for my Creality Cr-10, but the files should fit most printers. I ‎recommend starting with the lens base and servo goggle holders.‎

After these parts are printed, you will want to glue them to the goggle frames using the E6000 glue. I ‎chose this glue because it's strong yet flexible. I also recommend having some clips to hold down the ‎parts while the glue dries. ‎‎

Quick Hint: before you start gluing, make sure the lens base pointers are sitting at 1 o’clock and 11 ‎o’clock (or 135 degrees and 45 degrees for you technical people), this way the actual eyebrow will ‎move correctly. Trust me, I have glued them wrong before and had a mess.

Here is a quick sketch if you’re more of a visual person like myself.‎

After that, make sure everything is clipped and let it dry overnight. ‎‎

Step 2: Lens

This is probably the most difficult step. To start, print out the lens parts.

After you print the parts, you will have to carefully insert the leaves into the holes. Be patient; you ‎may need to file the hole a bit for them to fit. Once you have them inserted, fold them in and insert ‎them into the lens. This part may take some time and may be a bit frustrating, but your patience will ‎be rewarded.‎

Next, you should glue the iris on top of the lens base using the E6000. Make sure that the pull switch is ‎facing down and moves to the open position by going to the side.‎

I drew a sketch just in case my wording is confusing.‎

Let it dry overnight to make sure everything stays in place.

Step 3: Eyebrows and Testing

After everything is glued and secured, I recommend performing a test to ensure the assembly ‎operates correctly.‎

Print out the eyebrow parts and pulley hinges.‎

eyebrow_12 ‎

Attach the Eyebrows with the back hole facing outward and use screws to attach them. (Honestly, I ‎don't know what size screws as I recycle them from previous projects.) ‎

Locate the two hobby servos and attach the pulleys to the hobby servo horn. Then, insert the servos ‎into the servo holders. Screw them in if you can. They should look something like this.‎

servo_13 ‎

Next, I recommend testing the movement of the servos by moving them from 0 to 180 degrees to ‎verify the irises open and close and the eyebrows move.‎

Step 4: Preparing Goggles and Making Boxes

‎ I recommend starting the print for the circuit cups; these will hold the circuit and the battery for the ‎goggles.

Here is where we get clever. There is a wire on the inside of the goggles that will connect the two ‎circuit boxes. I recommend taking a Dremel or some type of cutting instrument and making a small ‎hole right behind the servo holder.‎‎

Next, after the circuit cups have been printed, glue them to the back of the servo holder like so.‎‎

I recommend making sure enough wire is pulled through since you will need it for the power and ‎maybe the servo as well. ‎

Of course, let it dry overnight. ‎

Step 5: Electronics ‎‎

Upload the code to the Adafruit Trinket. It's very important!

This is where your tinker/Maker skills come in. The diagram for this is a bit weird. I daisy-chained the ‎signal wires from the Trinket. Here is a diagram I quickly drew.‎‎

diagram_18

I made a connector from a perfboard to distribute power to all parts of the circuit.‎‎

Next, you will want to connect the power booster and the battery and place them into one cup. ‎‎

power_20

Add the trinket and the perfboard hack into the other cup.‎‎

add_21

The program should be already uploaded to the Trinket.

You can place the switch outside the circuit box of the battery holder, screw the covers to the circuit ‎cups, and you’re done. ‎

Extra‎

I made extra parts for aesthetic reasons. These are parts you can print for color designs that can be ‎glued to the eyebrows and the end of the lenses. I printed them in different colors so they can look ‎super cool.‎

I hope you enjoy making this project! If you make any modifications, be sure to post it online and tag ‎me!‎
