[Robin] is a hobby photographer with some very nice old film camera gear. But who has the money or patience for developing film these days? (Well, lots of people, especially artists, but that’s a different Hackaday article.) So to update his old gear without breaking the bank, he glommed a Sony Nex digital camera onto the back of a nice old Nikon, and documented the process for us.
A friend of mine once said, “never underestimate what a good engineer can do with a file and patience.” [Robin]’s hack essentially consists of grinding the Sony’s CMOS sensor to fit exactly where the film plane would be in the old Nikon. For him, this meant relocating the IR filter glass, because it wouldn’t fit with the shutter, and then slowly and accurately trimming down the edges of the CMOS sensor’s retaining frame until it was just right.
There’s been a spate of YouTube videos of people strapping GoPro cameras onto things recently. [Ruiz] at [Adafruit] is looking to contribute to this trend with this tutorial on 3D printing a GoPro Session toy car mount. The entire toy car mount is 3D printed, except for the axles, which are made of the unprinted filament with melted ends to hold the wheels in place.
The part of the mount that fits around the camera is printed in a flexible filament (think Ninjaflex), so it holds on tightly to the GoPro and can be used as a bumper as well. The car that fits into the base of the camera sleeve is designed to run on Hot Wheels track so that you can lay out your shots and keep the subject in frame. It’s a neat design that could be useful for creating an interesting point of view in a video.
If you have hotwheel, a GoPro (or other tiny camera), and 3D printer this is the project that will get you through the holiday without the kids driving you crazy. Good luck dear hackers.
Name the countries that house a manned space program. In order of arrival in space, USSR/Russian Federation, United States of America, People’s Republic of China. And maybe one day, Denmark. OK, not the Danish government. But that doesn’t stop the country having a manned space program, in the form of Copenhagen Suborbitals. As the tagline on their website has it: “We’re 50 geeks building and flying our own rockets. One of us will fly into space“. If that doesn’t catch the attention of Hackaday readers, nothing will.
The heat issue is addressed by removing the camera case and attaching its metal chassis directly to a heatsink that forms the end of an extruded aluminium case. Vibration was causing the camera SD cards to come loose, so these are soldered into their sockets. Power is provided by a pair of 18650 cells with a switching regulator to provide internal power, and another to allow the unit to be charged from a wide range of input voltages. A PCB houses both the regulators and sockets for cable distribution. There is even a socket on top of the case to allow a small monitor to be mounted as a viewfinder. Along the way they’ve created a ruggedized camera that we think could have many applications far beyond rocket testing. Maybe they should sell kits!
Taking a stroll through the woods in the midst of autumn is a stunning visual experience. It does, however, require one to live nearby a forest. If you are one of those who does not, [Koen Hufkens] has recently launched the Virtual Forest project — a VR experience that takes you though a day in a deciduous forest.
First off, you don’t need a VR apparatus to view the scenery. Web-browsers and most smart phones are capable of displaying the 360 degree images. The Raspberry Pi 2-controlled Ricoh Theta S camera is enclosed in a glass lamp cover and — with the help of some PVC pipe — mounted on a standard fence post. Power is delivered ingeniously via a Cat5e cable, and a surge protector has also been included in case of lightning strikes. Depending on when you view the website, you could be confronted with a black screen, or a kaleidoscope of color.
No one watches video anymore. Cable cutters are digging into Verizon’s profits, and YouTube is a shadow of its 2005 self. What are people consuming now? Animated gifs. This is the bread and butter of the meme economy. Personally, all my investments are sunk deep into Gandolf / Balrog gifs, with each character replaced with Trump and Hillary. I expect a tidy profit on November 9th.
With animated gifs being the de facto method of sharing moving pictures, the world will belong to those who can create them. Phones are fine, but strangely video cameras, DSLRs, and other high-end photography equipment are the norm. This is idiotic, of course, because high-definition images are just a fad, and audio is useless.
For the hardware, [Nick] went with a Raspberry Pi and Raspberry Pi camera. A combination of software ranging from PiCamera, GraphicsMagick, and GifCam turns this tiny bit of hardware into a machine dedicated to content creation in the hippest new medium. Other hardware includes a battery – either a normal LiPo ‘pouch’ cell, or an 18650 cell. Other hardware includes an Adafruit Powerboost 500 charge controller and a neat illuminated push button.
The 3D-printed enclosure is where this project really shines. Hearkening back to an older time, this camera includes a real viewfinder for all your gonzo giffing. The camera is charged through a completely normal USB port, and even the Pi’s SD card is accessible without disassembling the camera. There are even some paper wrappers for this camera to give it a 90s disposable camera aesthetic.
Of course, this isn’t the first camera dedicated to the creation of animated gifs. Before the C.H.I.P., Next Thing Co released OTTO, a camera designed for gifs. [Nick]’s project, though, is a camera dedicated completely to gifs. It is the greatest technical achievement of our time, for the creation of content in the greatest artistic medium.
The next giant leap for mankind is to the stars. While we are mostly earthbound — for now — that shouldn’t stop us from gazing upwards to marvel at the night sky. In saying that, if you’re an amateur astrophotographer looking to take long-exposure photos of the Milky Way and other stellar scenes, [Anthony Urbano] has devised a portable tracking setup to keep your photos on point.
When taking pictures of the night sky, the earth’s rotation will cause light trails during long exposures. Designed for ultra-portability, [Urbano’s] rig uses an Arduino UNO controlled Sanryusha P43G geared stepper motor coupled to a camera mounting plate on a small tripod. The setup isn’t designed for anything larger than a DSLR, but is still capable of taking some stellar pictures.
We are all (hopefully) aware that we can be watched while we’re online. Our clicks are all trackable to some extent, whether it’s our country’s government or an advertiser. What isn’t as obvious, though, is that it’s just as easy to track our movements in real life. [Saulius] was able to prove this concept by using optical character recognition to track the license plate numbers of passing cars half a kilometer away.
To achieve such long distances (and still have clear and reliable data to work with) [Saulius] paired a 70-300 mm telephoto lens with a compact USB camera. All of the gear was set up on an overpass and the camera was aimed at cars coming around a corner of a highway. As soon as the cars enter the frame, the USB camera feeds the information to a laptop running openALPR which is able to process and record license plate data.
The build is pretty impressive, but [Saulius] notes that it isn’t the ideal setup for processing a large amount of information at once because of the demands made on the laptop. With this equipment, monitoring a parking lot would be a more feasible situation. Still, with even this level of capability available to anyone with the cash, imagine what someone could do with the resources of a national government. They might even have long distance laser night vision!
