One Of The Largest Large Format Cameras You Will Ever Have Seen

When fate lands a very high quality lens in front of you, what do you do with it? If you are [Tim Hamilton], the solution is obvious. Use it in a huge large-format camera.

The lens came from a newspaper magnifier made redundant by digitalisation and used as a paperweight. It’s an extremely high quality piece of optical equipment so seeing it wasted in this way was a source of distress. So after characterising it an enormous scaled-up box and bellows was constructed, and set upon a suitably substantial wheeled tripod.

Instead of a huge piece of film or some unobtainable giant electronic sensor, the image is projected onto a large screen at the rear of the camera. A modern digital camera is mounted inside the box just beneath the lens and photographs the screen, resulting in the feel of the largest of large format cameras with the convenience of a digital format. The resulting images have a special quality to them that recalls pictures from the past, and definitely makes the camera a special if slightly inconvenient device.

This may be one of the larger cameras we’ve featured, but it’s not the first that uses a similar technique.

Hands-On Review: TCam-Mini WiFi Thermal Imager

A thermal camera is a tool I have been wanting to add to my workbench for quite a while, so when I learned about the tCam-Mini, a wireless thermal camera by Dan Julio, I placed an order. A thermal imager is a camera whose images represent temperatures, making it easy to see things like hot and cold spots, or read the temperature of any point within the camera’s view. The main (and most expensive) component of the tCam-Mini is the Lepton 3.5 sensor, which sits in a socket in the middle of the board. The sensor is sold separately, but the campaign made it available as an add-on.

Want to see how evenly a 3D printer’s heat bed is warming up, or check whether a hot plate is actually reflowing PCBs at the optimal temperature? How about just seeing how weird your pets would look if you had heat vision instead of normal eyes? A thermal imager like the tCam-mini is the tool for that, but it’s important to understand exactly how the tCam-mini works. While it may look like a webcam, it does not work like one.

Dominate Video Calls With Game Boy Camera Webcam

We can’t promise it will all be positive, but there’s no question you’ll be getting plenty of attention when you join a video call using the Game Boy Camera. Assuming they recognize you, anyway. The resolution and video quality of the 1998 toy certainly hasn’t aged very well, and that’s before it gets compressed and sent over the Internet.

From a technical standpoint, this one is actually pretty simple, if rather convoluted. [RetroGameCouch] hasn’t modified the Game Boy Camera in any way, he’s just connected it to the Super Game Boy, which in turn is slotted into a Super Nintendo. From there the video output of the SNES is passed through an HDMI converter, and finally terminates in a cheap HDMI capture device. His particular SNES has been modified with component video, but on the stock hardware you’ll have to be content with composite.

The end result of all these adapters and cables is that the live feed from the Game Boy Camera, complete with the Super Game Boy’s on-screen border, is available on the computer as a standard USB video device that can be used with whatever program you wish. If you’re more interested in recovering still images, we’ve recently seen a project that lets you pull images from the Game Boy Camera over WiFi.

DIY Camera Dolly Costs More Time Than Money

A camera dolly can be fantastic filmmaking tool, and [Cornelius] was determined to create his own version: the “Dope” DIY Dolly. The result not only upped his production quality, but was also entirely in line with his DIY approach to filmmaking in general.

A basic dolly design is straightforward enough: a flat platform with wheels, and some aluminum tubing upon which to roll. But while dolly assemblies are easy to purchase or rent, [Cornelius] found that his DIY version — which used easily sourced parts and about 80 hours worth of 3D printing — provided perfectly acceptable results, while opening the door to remixing and sharing with like-minded filmmakers.

Interested? Download the STL files to get started on your own version. As for the track, smooth metal pipe is best, but sometimes track made from PVC can do the job. [Cornelius] has a few additional STL files for those planning to make a base from 1″ PVC pipe, and those are on a separate download link near the bottom of the project page (here’s that link again.) Watch the Dope Dolly in action in the brief video embedded below.

On the other hand, if you prefer your DIY camera equipment to be on the smaller and more complicated end of the spectrum, be sure to check out this multi-axis camera slider.

Analog Camera Goes Digital

The digital camera revolution swept through the world in the early 2000s, and aside from some unique situations and a handful of artists still using film, almost everyone has switched over to digital since then. Unfortunately that means that there’s a lot of high quality film cameras in the world that are gathering dust, but with a few pieces of equipment it’s possible to convert them to digital and get some more use out of them.

[befinitiv]’s latest project handles this conversion by swapping in a Raspberry Pi Zero where the film cartridge would otherwise be inserted into the camera. The Pi is attached to a 3D-printed case which mimics the shape of the film, and also houses a Pi camera right in front of the location where the film would be exposed. By removing the Pi camera’s lens, this new setup is able to take advantage of the analog camera’s optics instead and is able to capture images of relatively decent quality.

There are some perks of using this setup as well, namely that video can be broadcast to this phone over a wireless connection to a computer via the Raspberry Pi. It’s a pretty interesting build with excellent results for a remarkably low price tag, and it would be pretty straightforward to interface the camera’s shutter and other control dials into the Raspberry Pi to further replicate the action of an old film camera. And, if you enjoy [befinitiv]’s projects of bringing old tech into the modern world, be sure to check out his 80s-era DOS laptop which is able to run a modern Linux installation.

Motorized Camera Slider Gives Your Shots Style

We’ve all seen those smooth panning shots, which combined with some public domain beats, are a hallmark of the modern YouTube tech video. Recreating that style in your own productions is as easy as pointing your browser to Amazon and picking up a motorized camera slider, so long as you don’t mind parting with a few hundred bucks, anyway. But [PaweÅ‚ Spychalski] had a better idea. He decided to build his own camera slider and make it an open source project so others could spin up their own versions.

His design uses many components that have become popular and affordable thanks to the desktop 3D printer explosion, such as 2020 aluminum extrusion, LM8UU linear bearings, an 8 mm lead screw, and a NEMA 17 stepper motor. In fact, if you’ve got a broken 3D printer that you don’t know what to do with, stripping it for parts would get you a long way towards completing the BOM for this project.

To control the slider, [PaweÅ‚] is using an ESP32 and TMC2209 “StepStick” driver connected to an OLED display and a few buttons. As designed, a smartphone connected to a simple web page hosted by the ESP32 is the primary method of controlling the camera, but the buttons and display on the slider itself gives you a physical backup should you need it.

If you need something a bit more advanced than a linear slider, we’ve seen some impressive DIY motion rigs that can spin the camera around the target and produce some very professional looking shots.

Bringing The Game Boy Camera Into The 21st Century

The Game Boy Camera is probably one of the most limited-specification digital cameras to have been mass-marketed, yet it occupies a special position in the hearts of many because despite being a toy with a paltry 128×128 monochrome sensor it was for many the first camera they owned. [Matt Grey] was among those people, and was always frustrated by the device’s inability to export pictures except to the Game Boy printer. So after having bodged together an interface a decade ago but not being happy with it, he returned to the project and made a wireless carrier for the camera that allows easy transfer through WiFi to his mobile phone.

Inside the slab-like 3D-printed enclosure lies a GBxCart RW Game Boy cartridge reader, whose USB port is wired to a Raspberry Pi Zero on which are a set of scripts to read the camera and make its photos available for download via a web browser. At last the camera is a stand-alone unit, allowing the easy snapping and retrieval of as many tiny black and white images as he likes. There’s a video showing the device in action, which we’ve placed for your enjoyment below the break.

This camera has appeared in so many projects on these pages over the years, but we’re guessing that the work on whose shoulders this one stands would be the moment its workings were reverse engineered.
