Kodak MC3: Everything But A Phone In 2001

One of the constants in consumer electronics is that designers will try to put as many features into a single device as possible, whether it’s a Walkman with a radio tuner or a new class of devices that crams a photo and video camera in the same enclosure as a music player. At the time that the Kodak MC3 was released this made it a rather unique device, with it in hindsight being basically a smartphone without the phone, as [Tech Tangents] aptly notes in his recent video on the device.

Six years before Apple’s iPhone would be announced, and eight years before the first iPod with a video camera, the Kodak MC3 was in many respects bleeding edge technology targeted straight at tech enthusiasts. For less than $300 you got VGA-quality images, CompactFlash storage, and MP3 playback capability. The videos it produced were 320×240 resolution, h.263 encoded MOVs with a maximum length of 4 seconds at 20 FPS, or 4 minutes with a 64 MB CF card.

The unit that [Tech Tangents] got used came with a 128 MB CF card, but couldn’t use a 2 GB CF card, which is a shame. The screen on it got a lot of flak for not not having a backlight, but this was common for the era, as were the poor viewing angles. Ditto for the poor video quality, as anyone who invested in consumer digital cameras in the early 2000s can attest to. In that respect this Kodak device was probably a bit too ambitious with its features for the era, maybe to compensate for it completely missing the boat on the rise of digital camera technology around the time.

The Surprising Hackability Of A Knock-Off Chinese Toy Camera

My colleague Lewin on the other side of the world has recently bought himself a new camera. It’s a very cute little thing, a Kodak Charmera, the latest badge-engineered device to carry the venerable photography company’s name. It’s a keyring camera, not much bigger than my thumb, and packing a few-megapixel sensor and a little fixed-focus camera module. They’re all the rage and thus always sold out, so when I saw something similar on AliExpress for just under a tenner I was curious enough to drop in an order. How bad could it be?

A Blatant-Knock-Off With Interesting Internals

My G6 Thumb Camera arrived a few days later, as straightforward a copy of a branded product as I have seen, and while it’s by any measure not a high quality camera, I am pleasantly surprised how bad it isn’t. I’ve received a three megapixel camera with image and movie quality that’s far better than that of the kids toy cameras I’ve played with before at a similar price, and that’s something I find amazing. This isn’t a review of a cheap camera, instead it’s an investigation of what goes into a camera like this one. How can they make a camera that’s almost useful, for under a tenner?

It’s Not A Leica, It’s A Lumix

There’s an old adage in photography that the best camera in the world is the one in your hand when the shot presents itself, but there’s no doubt that a better camera makes a difference to the quality of the final image. Among decent quality cameras the Leica rangefinder models have near cult-like status, but the problem is for would-be Leica owners that they carry eye-watering prices. [Cristian Băluță] approached this problem in s special way, by crafting a Leica-style body for a Panasonic Lumix camera. Given the technology relationship between the Japanese and German companies, we can see the appeal.

While the aesthetics of a Leica are an important consideration, the ergonomics such as the position of the lens on the body dictated the design choices. He was fortunate that the internal design of the Lumix gave plenty of scope for re-arrangement of parts, given that cameras are often extremely packed internally. Some rather bold surgery to the Lumix mainboard and a set of redesigned flex PCBs result in all the parts fitting in the CNC machined case, and the resulting camera certainly looks the part.

The write-up is in part a journey through discovering the process of getting parts manufactured, but it contains a lot of impressive work. Does the performance of the final result match up to its looks? We’ll leave you to be the judge of that. Meanwhile, take a look at another Leica clone.

There’s Nothing Mini About This Mini Hasselblad-Style Camera’s Sensor

When someone hacks together a digital camera with a Raspberry Pi, the limiting factor for serious photography is usually the sensor. No offense to the fine folks at the foundation, but even the “HQ” camera, while very good, isn’t quite professional grade. That’s why when photographer [Malcolm Wilson] put together this “Mini Hasselblad” style camera, he hacked in a 1″ sensor.

The sensor in question came in the form of a OneInchEye V2, from [Will Whang] on Tindie. The OneInch Eye is a great project in its own right: it takes a Sony IMX283 one-inch CMOS image sensor, and packages it with an IMU and thermal sensor on a board that hooks up to the 4-lane MIPI interface on the Raspberry Pi CM4 and Pi 5.

Sensor in hand, [Malcolm] needed but to figure out power and view-finding. Power is provided by a Geekworm X1200 battery hat. That’s the nice thing about the Pi ecosystem: with so many modules, it’s like LEGO for makers. The viewfinder, too, uses 4″ HDMI screen sold for Pi use, and he’s combined it with a Mamiya C220 TLR viewfinder to give that look-down-and-shoot effect that gives the project the “Mini Hasselblad” moniker.

These are a few images [Malcom] took with the camera. We’re no pros, but at least at this resolution they look good.
The steel-PLA case doesn’t hurt in that regard either, with the styling somewhat reminiscent of vintage film cameras. The “steel” isn’t just a colour in this case, and the metal actually makes the PLA conductive, which our photographer friend learned the hard way. Who hasn’t fried components on a surface they didn’t realize was conductive, though? We bet the added weight of the steel in the PLA makes this camera much nicer to hold than it would be in plain plastic, at least.

The OneInchEye module came set up for C-mount lenses, and [Malcolm] stuck with that, using some Fujinon TV lenses he already had on hand. [Malcolm] has released STL files of his build under a Creative Commons NonCommercial license, but he’s holding the code back for subscribers to his Substack.

This isn’t the first Pi-based camera we’ve seen from [Malcolm], and there’ve been quite a few others on these pages over the years. There was even a Hackaday version, to test out the “official” module [Malcolm] eschewed.

An Open Source Mirrorless Camera You’d Want To Use

Making a digital camera is a project that appears easy enough, but it’s one whose complexity increases depending on the level to which a designer is prepared to go. At the simplest a Raspberry Pi and camera module can be stuck in a 3D printed case, but in that case, the difficult work of getting the drivers and electronics sorted out has already been done for you.

At the other end of the scale there’s [Wenting Zhang]’s open source mirrorless digital camera project, in which the design and construction of a full-frame CCD digital camera has been taken back to first principles. To understand the scale of this task, this process employs large teams of engineers when a camera company does it, and while it’s taken a few years and the software isn’t perhaps as polished as your Sony or Canon, the fact it’s been done at all is extremely impressive.

Inside is a Kodak full-frame sensor behind the Sony E-mount lens, for which all the complex CCD timing and acquisition circuitry has been implemented. The brains of the show lie in a Xilinx Zynq ARM-and-FPGA in a stack of boards with a power board and the CCD board. The controls and battery are in a grip, and a large display is on the back of the unit.

We featured an earlier version of this project last year, and this version is a much better development with something like the ergonomics, control, and interface you would expect from a modern consumer camera. The screen update is still a little slow and there are doubtless many tweaks to come, but this really feels close to being a camera you’d want to try. There’s an assembly video which we’ve placed below the break, feast your eyes on it.

Designing A Quality Camera Slider Can Be Remarkably Satisfying

Camera sliders are great creative tools, letting you get smooth controlled shots that can class up any production. [Anthony Kouttron] decided to build one for an engineering class, and he ended up mighty satisfied with what he and his team accomplished.

As an engineering class project, this wasn’t a build done on a whim. Instead, [Anthony] and his fellow students spent plenty of time hashing out what they needed this thing to do, and how it should be built. An Arduino was selected as the brains of the operation, as a capable and accessible microcontroller platform. Stepper motors and a toothed belt drive were used to move the slider in a controllable fashion. The slider’s control interface was an HD44780-based character LCD, along with a thumbstick and two pushbuttons. The slider relied on steel tubes for a frame, which was heavy, but cost-effective and easy to fabricate. Much of the parts were salvaged from legendary e-waste bins on the university grounds.

The final product was stout and practical. It may not have been light, but the steel frame and strong stepper motor meant the slider could easily handle even heavy DSLR cameras. That’s something that lighter builds can struggle with.

Ultimately, it was an excellent learning experience for [Anthony] and his team. As a bonus, he got some great timelapses out of it, too. Video after the break.

A Mouse Becomes A Camera

If your pointing device is a mouse, turn it over. The chances are you’ll see a red LED light if you’re not seriously old-school and your mouse has a ball, this light serves as the illumination for a very simple camera sensor. The mouse electronics do their thing by looking for movement in the resulting image, but it should be possible to pull out the data and repurpose the sensor as a digital camera. [Doctor Volt] has a new video showing just that with the innards of a Logitech peripheral.

The mouse contains a microcontroller and the camera part, which fortunately has an SPI interface. The correct register to query the sensor information was deduced, and as if my magic, an image appeared. An M12 lens provided focus with a handy 3D printed mount, and the board went back into the mouse case as a housing. The pictures have something of the Game Boy camera about them, being low-res and monochrome, but it’s still a neat hack.

If you’d like to give it a go you can find the code in a GitHub repository. You might find it worth finding a gaming mouse though, for the much higher resolution sensor.
