Phone Locking Mechanism For FPV Racing Goggles

2015-05-12 10.18.23-1

This is the phone locking mechanism I’ve designed for my First Person View (FPV) racing goggle university project.  On the left is the initial test piece and on the right the final test piece.  A clockwise twist will lock the phone into position and when you want to release it, press the button and rotate it anti-clockwise.  Simples!  To use that is, designing it all to fit into a headset and accommodate several phone sizes… not so simples.

3D Printed Lens Cap

Inner Spring

Last week I ordered an Olympus 35 RC analogue film camera.  I paid a good price but unfortunately it didn’t come with a lens cap or case.  Fortunately for me I have the know-how and technology to design and make my own lens cap.

The image above shows the lens cap without the outer case on.  I designed the sprung locking mechanism so that it could use the resistance of the form and material to lock it into position.

This is the first revision of the lens cap and a few changes need to be made.  Stay tuned, I’ll add more pictures as I develop it further.

Let me know what you think and if there any design improvements I could make.

Houston, We Have Photographs

As promised, and a little late I know, my apologies…  Some pinhole photographs from Proto 2! (Ticker tape, klaxon horns, ‘splosions!!!)  These were shot on Fomapan 120 ISO 400.  I developed them at home and photographed them using my smartphone, ran them through Photoshop and inverted the image, BOOM.  I’m sure they could be clearer but I did the best with whats I gats.

Out And About With Proto 2

The second prototype functioned much better after the minute changes made from Proto 1.  The shots came out much better too as I gave a lot more exposure time and used 400 ISO film instead of 100.2015-01-21 12.40.50 The 3D printed tripod mount really improved stability and allowed me to angle the camera.  And I promise, once I get a half decent method of processing the negatives I will upload the photos for all to see.  Stay tuned!

3D Print Your Knob

That got your attention!  No, I’m talking about the knob on my pinhole camera.

2015-01-15 13.47.57I designed and 3D printed the spool adapter and winder for my Pinhole Moments camera.  The spool is a standard spool that you get with any 120 film.  I designed the winder so there is a force fit that is strong enough to lock into position but easy enough to remove without Hulk-smashing the cardboard pinhole camera upon removal.

Taking Photos With Pinhole Moments – Proto 1

2015-01-17 13.47.462015-01-17 15.36.19

Out and about with Ellie taking photos with the first Pinhole Moments prototype.  Photo results coming soon.

Fast Prototyping, Fast materials, Fast Learning

I used temporary methods that were adequate for the prototyping stages.

Although the light chamber will have printed inner walls, I used a thick marker pen to black out the chamber.

I plan to use transparent red acetate sheet for the shot number window.  Keen to test the camera and with plenty of post Christmas sweets lying around, I used some clear red wrapping from a Quality Street chocolate.
