These goggles, as if straight out of a sci-fi b-movie, have servo motors that noisily control dark lenses depending on the ambient light and proximity...
2 servos welding goggles duct tape wire a microcontroller a proximity sensor a photoresistor a resistor
Solder the photoresistor to the resistor to create a voltage divider (you should pick a resistor on the same order of magnitude as your photoresistor)...
I found that it was helpful to extend the length of the wires on my two servos and proximity sensor, so I just soldered on some extra long wires. I ac...
You'll end up having four ground wires and four 5V wires. Each sensor and servo takes a Vin and a ground. You'll want to group these all together to o...
Remove the dark lenses from your welding goggles.
Out comes the duct tape!
More tape!
You should also get a general idea of where you are going to route all your wires. I put my 5V wires to the right, my ground wires to the left, and th...
Tape on the servo so the lenses overlap the eyeholes when the servo is at one of its maximum values.
I preferred to loop long coils of wire to enhance the "sci-fi b-movie" effect, but if you want to cut yours short and practical, you can do that too.
I ended up with 6 wires. Inputs to the two servos, outputs from the two sensors, a 5V wire, and a ground wire. The 5V and ground go to their respectiv...
I used the servo library to program my arduino (full code below). #include Servo servo1; // create servo object to control a servo Servo servo2; in...
You could wire the arduino to a battery to make the goggles mobile. You could try using a magnifying lens or gears and an aperture or something entire...
