#3DPrint a Hot Swap Canon EOS M Battery Grip #celebratephotography

Great build from funkster.org:

I invested many many hours and a fair chunk (probably even enough to buy a nicer camera) of cash designing and building a battery grip that can be fed freshly charged 18650s without ever having to power down the camera or take it off its mount.

Great project from Mitch K on Hackster.io:

I didn’t have a nice camera that was capable of incremental photos. In the past I have used my iPad mini to do some time lapses but those were just over a couple hours. I want long term like days into weeks. So I decided to use a Raspberry Pi I had laying around and see what I could make with that.

Polaroid OneStep+ Splitzer #3DThursday #3DPrinting

Polaroid OneStep Splitzer by sleepaf Thingiverse

Get creative with Polaroid double exposures shared on Thingiverse:

Lens splitzer for double exposure on the Polaroid OneStep+. This covers half of the lens to keep half of the film undeveloped when shooting double exposures. To use, adjust the splitzer to cover half of the lens, take one exposure, turn the splitzer 180deg to cover the other half of the lens, and take the second exposure.

I added arrows on the edge to remind myself to turn it clockwise because the gray plastic on the lens snaps off if turned counterclockwise with enough force.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Make a MIDI Adobe Lightroom Controller #celebratephotography

With a swap here and an addition there, mkey05 made an awesome version of our Mini UNTZtrument: 3D Printed MIDI Controller that controls Lightroom! From Hackster.io:

So, I slightly revised the main body but mainly followed their detailed instructions to put it all together. I additionally drilled 4 holes (2 on each side) for the 4 pushbuttons. The pushbuttons I used are IP67 rated – not that I want them to use in the rain – but I choose them for their size (especially the connectors end), comfort and how nicel they click.

PiDSLM, Raspberry Pi DSLM #piday #raspberrypi @Raspberry_Pi

Loving this DSLM by Nick Engmann on Hackster.io:

I got really excited to put my design skill to work to create an enclosure that could transform the new module into a standalone DSLM (Digital Single Lens Mirrorless). Something that I could charge up, and take with me to take pictures of personal projects, nature, and friends

3D Printing in Ophthalmology: Smartphone Slit-Lamp Adapter for Diagnostics

A trio of researchers from hospitals in Egypt and India recently published a paper, titled “Custom-made three-dimensional-printed adapter for smartphone slit-lamp photography,” about their work designing a custom 3D printed smartphone slit-lamp adapter for photography applications in ophthalmology. A slit-lamp consists of a high-intensity light source, used with a biomicroscope, that can be focused to shine light into the eye for examination of the anterior and posterior segments in order to diagnose many conditions, like macular degeneration, cataracts, corneal injuries, and a detached retina.

3D printed adapter fixed on eyepiece to refine the sizing.

Many people have smartphones these days, and they are being paired more often with 3D printing for diagnostic and imaging purposes, especially in the offices of eye doctors.

“Smartphone photography in ophthalmology has a wide variety of uses including examination with or without other examination tools such as slit lamp or condensing lenses,” the researchers wrote. “Smartphones can be used for fundus photography,[2],[3],[4] slit-lamp photography,[5] microscope-free anterior segment photography,[6] gonioscopy,[7] and more.[5]

3D printed adapters can help make these tasks more efficient, as they are a quick, low-cost option. Custom adapters are built for just one smartphone design and slit lamp, while universal adapters can be adjusted to fit many designs. There are pros and cons for each option, which is why these researchers chose to “combine the advantages of both approaches” for their 3D printed smartphone slit-lamp adapter.

Two copies of the blink 3D printed slit-lamp adapter (in gray and black ABS material) fixed to universal smartphone holders.

“It is built upon a commercially available part used in selfie sticks and tripods which is used to hold the phone,” they explained. “The rest of the adapter is designed and 3D printed to enable attaching the mobile with that holder to the selected eyepiece.”

Smartphone fixed on the Blink adapter and placed on slit-lamp eyepiece.

The goal was to make a design that complements different slit-lamps and automatically fits the microscope eyepiece that slides into the adapter; gravity, plus the weight of the smartphone, will keep it in place.  Then all of you have to do is place the phone’s camera against the eyepiece. The team named their creation Blink, for its “ease of use and quick adjustment like in a blink of an eye.”

After they chose their target slit-lamp microscope, the researchers used Vernier calipers to measure the eyepiece, and used the dimensions to create a CAD model of the adapter in Tinkercad. They refined the model using SketchUp, and prepared it for printing with Repetier software. The adapter was then 3D printed out of ABS material on a Rostock MAX v2 3D printer from SeeMeCNC.

Measurements of slit-lamp eyepiece being taken with digital Vernier calipers.

The 3D printed adapter was then fixed to the universal smartphone holder, and finally the fitting was “tested and refined to account for manufacturing tolerances.” Once the smartphone was placed in the holder, the device was attached to the slit-lamp’s eyepiece for easy imaging.

“The blink 3D-printed smartphone slit-lamp adapter was successfully designed, modeled, 3D-printed, and tested,” the researchers wrote. “Each type of slit-lamp eyepiece required a small modification in the 3D design based on measurements. Good-quality images could be captured in diffuse, slit, retro, and cobalt-blue illumination.”

The time it took to remove and modify the device was only seconds, which makes the 3D printed adapter very useful in slit-lamp photography.


“More units can be easily made by printing the same CAD file and fixing it to the universal smartphone holding bracket,” the researchers noted.


Additionally, the team confirmed that they could image the fundus – the part of the eyeball opposite the pupil – using a 90D lens.


“Our article describes the process of designing and building a smartphone slit-lamp adapter to solve the problem of slit-lamp photography,” the researchers concluded. “The cost of 3D printing a small part such as the adapter described here is small and can be done at a 3D printing shop which is available in all major cities in India, Egypt, and many other countries. Most of the work involved is in designing the CAD model according to measurements and physical constraints.

“Development of this type of innovation from idea to virtual design to hardware does not need much time or money – only an innovative mind and the drive to learn these new techniques.”

View and Convert Negatives with #RaspberryPi and #3DPrinting #celebratephotography


FLKPW7XK6KVLPWC LARGE

From Random_Canadian on Instructables:

I recognize that there are various apps for my smart phone but I was unable to get satisfactory results so this is what I came up with…

I wanted to be able to view them in real time as actual pictures. I can manually sort through the negatives and record only the ones that I want.
