EoS Project By Konnor Beaulier

Progress: All of my parts arrived! The best part is that the LRF module, Arduino, and OLED display are much smaller than I anticipated, however after drawing up some rough placement plans I can see that the width may in fact still be an issue. If width does prove to be a problem I can then look at the fallback plan of splitting the device on both sides of the glasses and figuring out what I need to use to connect the two sides.

LRF module

Arduino micro pro

OLED display

Issues: The lenses I have are excellent at reflecting light so I think they’ll work well for the OLED display, however my only concern is looking through them is a real eyesore. This may not prove to be a problem depending on how small I can make the display, but if it is too big and is a real nuisance then I may need to find a different lens to use.

Next: I don’t have wires small enough to test my electronic components so I’ll be looking to either get some in class or pay a visit to the engineering building to try and get some if possible. Once I get those I’ll be able to hook up the Arduino and the OLED display to get that displaying properly and will even be able to work on getting the readings from the LRF module which is great.

Project Title: EoS

Members: Konnor Beaulier

Description: I will be making wearable range finder glasses with a heads up display, so the user can determine the distance of an object and the distance will show on a lens in front of their eye.

 

A lot of the concept and inspiration came from: http://www.instructables.com/id/Arduino-Data-Glasses-for-My-Multimeter/

Where this man made arduino glasses for his multimeter with a heads up display. So even though I will be straying from his original plan and look, I will be using this as a base:

Here we can clearly see the heads up display as well as the casing for the circuitry. However, a big difference is that my range finder glasses will have the two lenses for the range finder module on the outside of the glasses, next to the lens of the heads up display.

 

Materials:

• LRF (laser range finder) module, 100m distance: $47
• Arduino pro micro chip: $9
• Glass lens for the display: $6
• OLED micro display: $15
• Small plastic mirror: Depends on schematic
• Battery: Only if needed
• Charger circuit: Depends on total power needs

Timeline:

Week 1:

• Order all of the supplies needed

Week 2:

• Beginning assembling the prototype
• Get a rough housing of the circuits created

Week 3:

• To have the OLED display and the arduino displaying the correct results
• If the LRF module arrives in time, get that coordinated as well
• Start calculating the optics numbers needed

Week 4:

• LRF shows correct distance and it is displayed in the OLED screen
• Cut the lens to the sizes needed
• Work on final housing

Week 5:

• Assemble all the circuits with the optics, test to make sure it displays
• Create final housing, 3D printing?

Week 6:

• Testing and fine tuning
• Improvements if needed

 

Fallback:

A big fallback would result if the actual device is too wide or too heavy to sit on one side of the glasses, which would result in me having to switch the LRF module to the other side of the glasses. Then my casing would have to loop behind the user’s head, connecting the microcontroller to the LRF and supporting the device and glasses as well. Another fallback would be if the LRF never comes due to shipping issues or if I can’t get it to work properly. In this case I’ll get a much shorter range module on sparkfun for about $15 just to get the initial outline of the project working. I’ll set the cutoff for all of this at the end of week 3/beginning of week 4 where I should have the LRF module and know how to use it.
