Anti-Social Glasses




You look up, they tilt down! A tilt switch controls 2 servos which open/ close shutters on a pair of custom glasses.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Parts

(1) 30 x 60 cm plastic sheet (We used polystyrene but its up to you!)

(1) 100cm x 1mm steel rod or equivalent

(2) Servo motors (Smaller is better, we used

(1) Tilt switch sensor

(1) Arduino Uno

(1) 5V power supply


Plastic Glue

A head and set of eyes!

Step 2: Mechanism

Critical to the glasses is the shutters which are actuated by a servo.

We wanted to use as few mechanical parts as possible to move the glasses shutters.Initially, we wanted to use a 4-bar linkage BUT this did NOT work with the pivot radius of the rods. We reduced the mechanism to a single arm with a slot that pushes the rods in a synchronized fashion direct from the servo motor. It is important to note the servo rotates 30 degrees to open and close the shutters. The parts are found in the attached CAD file for fabrication.

Step 3: Fabrication Assembling

Lasers! Download the file (we did all the heavy lifting) and get it cut! We set everything up for 1 mm material. We used Polystyrene but you can use whatever you like (maybe even clear?)

1-Cut profiles (We used a laser cutter!)

2-Glue Appropriate Layers (Front + Sides) See Diagram

3-Bend Rods + insert to frame

4-Attach servos (Don’t forget the mounting plates!)

5-Glue sides to frame front (Reinforce maybe)

6-Connect servo arm to hinge mechanism

7-Glue on shutters (Bottom up!)

8-Attach Tilt Switch (Might have to be tuned based on how far you want to tilt your head back)

9-Your ready to be anti-social!

Step 4: Arduino

How to sensing when it needs to close/open and being an anti-social person? We start thinking when you are working or reading and someone want to talk to you, you need to look up or look straight.

Basically, the movement of your head is moving and also angle, so in the beginning, we are looking 6-axis or 3-axis accelerometer to provide the angle which to control the servo. Due to the size of the accelerometer is too big for the glasses, and most important is we don't need that much angle data.

Thinking more about how to design a glasses simple and keep the project could be more affordable for people. so following the idea, we found the tilt switch is a nice solution to sensing the angle and still provide enough data to active the servo. It super CLEAN and SIMPLE!

We studying the position and angle to place switch on the glasses found the best is close to the front and rotate it a bit. The Last step is controlling better! When we trying to get the signal from the switch, if just setting the input is HIGH/LOW will get buzzing, and we couldn't use the delay function it will slow the reaction! So we trying using the analog to read the data, and it works almost perfectly.

    Nice idea but I think you made it way to complex. I would just have a pendulum weight that would close the flaps whenever you look up. No wires or batteries!

    I think you are missing one thing; Such a solution would not be fun!

    After all, the first unofficial commandment here at instructables is that all solutions are good, except the boring ones.

    I have to admit, though, that I touched on the same thought myself. I couldn't help associating to dolls that "fall asleep" when you put them down. Their sleepy eyes are most certainly not powered by an electric motor.

    I didn't uinderstand the use of these glasses...


    Question 1 year ago on Introduction

    Are you sure you don't mean asocial glasses? There's a big difference.

    hahaha best glasses ever! I need them

    how freakin' stylish is that

    Anti-social glasses? I need them.

    This looks like such a clever and funny idea! Will you be adding an intro at some point? I'm curious to read the background as to why you made these :)

    Yap, we upload all the details today.
    Basically, this is an assignment for ITECH master program in robotic fabrication and computational seminar. The topic is a useless robot, the idea starts on the social embarrassing moment. The reactions of the device could help us to be anti-social and it still with a nice way tell others you are working.
