Budget Astrophotography With A Raspberry Pi
http://hackaday.com/2017/04/20/budget-astrophotography-with-a-raspberry-pi/
New to astrophotography, [Jason Bowling] had heard that the Raspberry Pi’s camera module could be used as a low-cost entry into the hobby. Having a Raspberry Pi B+ and camera module on hand from an old project, he dove right in, detailing the process for any other newcomers.
Gingerly removing the camera’s lens, the module fit snugly into a 3D printed case — courtesy of a friend — and connected it to a separate case for the Pi. [Bowling] then mounted he camera directly on the telescope — a technique known as prime-focus photography, which treats the telescope like an oversized camera lens. A USB battery pack is perfect for powering the Pi for several hours.

BINOCULARS TO PINOCULARS: BUILD A LONG-RANGE RECORDING DEVICE
https://www.raspberrypi.org/magpi/binoculars-pinoculars/
The PiNoculars project is an excellent way to recycle an old pair of binoculars into a high-tech zoom recording device
The Raspberry Pi Camera Module is a great tool for digital making. With it, you can quickly add an 8-megapixel camera to the Raspberry Pi board.
The Camera Module is fantastic for video and still photography projects, such as time-lapse cameras. OpenCV software makes it easy to add computer vision to your projects. With this, you can train a Raspberry Pi to identify objects and react accordingly.
Created by digital maker Josh Williams, PiNoculars are a regular set of binoculars, with a Raspberry Pi Camera module fixed over one of the eyepieces.
“The camera mount should barely cover the eyepiece,” says Josh. It doesn’t have to be perfect, but try to position the camera mount as close to the centre of the eyepiece as possible.
“There are a number of people who’ve combined the Raspberry Pi with microscopes and telescopes,”

Get Up Close to your Soldering with a Pi Zero Microscope
http://hackaday.com/2017/04/26/get-up-close-to-your-soldering-with-a-pi-zero-microscope/
Do your Mark 1 Eyeballs no longer hold their own when it comes to fine work close up? Soldering can be a literal pain under such conditions, and even for the Elf-eyed among us, dealing with pads at a 0.4-mm pitch is probably best tackled with a little optical assistance. When the times comes for a little help, consider building a soldering microscope from a Pi Zero and a few bits and bobs from around the shop.
Affordable commercial soldering scopes aren’t terribly hard to come by, but [magkopian] decided to roll his own by taking advantage of the streaming capabilities of the Raspberry Pi platform, not to mention its affordability. This is a really simple hack — nothing is 3D-printed or custom milled.

Hackaday Prize Entry: Rangefinder + Camera = SmartZoom
http://hackaday.com/2017/05/23/hackaday-prize-entry-rangefinder-camera-smartzoom/
The interesting thing about submissions for The Hackaday Prize is seeing unusual projects and concepts that might not otherwise pop up. [ken conrad] has a curious but thoughtfully designed idea for Raspberry Pi-based SmartZoom Imaging that uses a Pi Zero and camera plus some laser emitters to create a device with a very specific capability: a camera that constantly and dynamically resizes the image make the subject appear consistently framed and sized, regardless of its distance from the lens. The idea brings together two separate functions: rangefinding and automated zooming and re-sampling of the camera image.
The Raspberry Pi uses the camera board plus some forward-pointing laser dots as a rangefinder; as long as at least two laser dots are visible on the subject, the distance between the device and the subject can be calculated. The Pi then uses the knowledge of how near or far the subject is to present a final image whose zoom level has been adjusted to match (and offset) the range of the subject from the camera, in effect canceling out the way an object appears larger or smaller based on distance.

Cheap 360 Degree Camera
http://hackaday.com/2016/10/09/cheap-360-degree-camera/
How much would you pay for a 360 degree camera? How about $15 if you already have a Raspberry Pi and a Pi camera hanging around? If you don’t, you’ll have to add that minimal cost into the build. [Gigafide] noticed how a spherical mirror, made to see around corners, showed an all-around view if you took a picture of it from below. He snagged a panoramic lens made for an iPhone and stripped it for its optics. Some custom software and a little work resulted in a usable 360 degree camera.
SimpleCV (a light version of OpenCV) provides the algorithms to unwrap the frames and you can take video with the setup (see the video below). Mounting the optics took some 3D printing and the Pi operates as a hot spot to send the video out.

Flypi – cheap microscope/experimental setup
https://hackaday.io/project/5059-flypi-cheap-microscopeexperimental-setup
Pi + Picamera + M12 lens + Arduino microscope/experimental setup for diagnostics and scientific experiments!
Our plan with this project is to develop a complete opensource and cheap device for scientific experiments (data collection and analysis) and diagnostics (if they are “microscopy based”).
So far we were able to perform some proof of principle experiments in life sciences (Fluorescence and calcium imaging, opto and thermo genetics essays) and to perform diagnostics of the following parasites: Loa loa, Brugia Malayi, Wuchereria bankrofti, Schistosoma eggs, Mansonella perstans
The setup is quite simple:
A raspberry pi 2 (or 3) (running Raspian) + picamera with mounted lens (M12 standard) + some python3 code (for custom GUI + saving of data) do most of the lifting and an Arduino + custom PCB + electronic bits take care of timing, light stimulation, heating, temperature sensing and any other physical interaction necessary.

Sneak Thieves Beware: A Pi Watcheth
http://hackaday.com/2017/07/13/sneak-thieves-beware-a-pi-watcheth/
Ever have that strange feeling that somebody is breaking into your workshop? Well, Hackaday.io user [Kenny] has whipped up a tutorial on how to scratch that itch by turning a spare Raspberry Pi you may have kicking around into a security camera system that notifies you at a moment’s notice.
The system works like this: a Raspberry Pi 3 and connected camera module remain vigilant, constantly scanning for motion and recording video. If motion is detected, it immediately snaps and sends a picture to the user’s mobile via PushBullet, then begins recording video. If there is still movement after a few seconds, the process repeats until the area is once again devoid of motion. This also permits a two-way communication with your Pi security system, so you can check in on the live feed whenever you feel the urge.
setup requires setting up a PushBullet account as well as installing it on your mobile and linking it with an API. For your Pi, you can go ahead with setting up some Python PushBullet libraries, installing FFmpeg, Pi Camera Notifier, and others. Or, install the ready-to-go image

The Perfect Tourist Techno-Cap
http://hackaday.com/2017/07/24/the-perfect-tourist-techno-cap/
How many times are you out on vacation and neglect to take pictures to document it all for the folks back at home? Or maybe you forgot just exactly where that awesome waterfall was. [Mark Williams] has made a Raspberry Pi Zero enabled cap that can take photos and geotag them with the location as well as the attitude of the camera.
The idea is to enable the reconstruction of a trip photographically. The hardware consists of a Raspberry Pi Zero W coupled with a Raspberry Camera V2 and a BerryGPS-IMU. Once activated, the system starts taking photos every two minutes. Within each photograph, the location of the photographer is recorded like most GPS enabled camera.

Components used were;
Raspberry Pi Zero W
BerryGPS-IMU
Raspberry Camera V2

Hackaday Prize Entry: FabDoc is Version Control for Project Images
http://hackaday.com/2017/08/11/hackaday-prize-entry-fabdoc-is-version-control-for-project-images/
FabDoc is an interesting concept that attempts to tackle a problem many of us didn’t realize we had. There are plenty of version control systems for software, but many projects also have a hardware element or assembly process. Those physical elements need to be documented, but that process does not easily fit the tools that make software development and collaboration easier. [Kevin Cheng] sums FabDoc up as “a system to capture time-lapse pictures as pre-commits.”
With FabDoc a camera automatically records the physical development process, allowing the developer to focus on work and review later. The images from the camera are treated as pre-commits. Upon review, the developer selects relevant key images (ignoring dead ends or false starts) and commits them. It’s a version control and commit system for the physical part of the development process.

A Camera That Encrypts Images with GPG
https://blog.hackster.io/a-camera-that-encrypts-images-with-gpg-64c41fefc35a
Last year over 150 filmmakers and journalists called on the big camera manufacturers to sell encrypted cameras. While your phone might come with encryption out of the box, high end cameras used by professional photojournalists and film makers do not. That leaves them open to having their cameras seized, and the images and video examined by law-enforcement and security forces.
Depending on where they are—and what they’re reporting on—the contents of those images and video could mean their own imprisonment, along with the imprisonment, torture, or even death, of their sources.
“I’ve made a proof-of-concept encrypting digital camera based on the open source, widely adoped GnuPG. This project uses public key encryption to encrypt every photo the camera takes before writing the encrypted version to memory. Of particular note, there are absolutely no UI changes over what an ordinary point-and-shoot camera provides. No extra keyboards or touch screens are needed as no passwords need be entered.” — Aaron Waychoff

Simplify the way of documenting projects in software and hardware, based on Raspberry Pi Zero and camera module
We are all facing a lot of works of documentation beyond making, especially when we would like to share and collaboratively develop “hardware” projects.
There are too many version control system (VCS) tools for “software” projects so that we could fortunately join any large-scale software projects, such as Linux, if they are open source. But what happen to “hardware” projects? Can we enlarge the scale of these projects with VCS tools?
There are too many physical details (materials, machines, parameters…) which should be well-documented before cooperating, but unfortunately cannot be easily digitized into documentation or VCS.
We are trying to hack the way of documenting for all of makers’ projects, simply with Raspberry Pi + camera module, and an experimental platform.

YouTube has the ability to do live streaming, but [Tinkernut] felt that the process could be much more straightforward. From this desire to streamline was born the Raspberry Pi based YouTube live streaming camera. It consists of a Raspberry Pi with some supporting hardware and it has one job: to make live streaming as simple as pointing a box and pressing a button. The hardware is mostly off-the-shelf, and once all the configuration is done the unit provides a simple touchscreen based interface to preview, broadcast live, and shut down. The only thing missing is a 3D printed enclosure, which [Tinkernut] says is in the works.

Stunning Fake Polaroid Camera Performs Magic

It’s high time us Muggles got our hands on the hardware used to take Magical Photographs as seen in The Daily Prophet. The first pioneering step in that direction has been taken by [Abhishek] who built this moving picture taking polaroid-ish camera, which he’s calling the “Instagif NextStep”. It’s a camera that records a short, three second video, converts it to GIF and ejects a little cartridge which displays the animated photo.
The enclosure and all of the internal mechanical parts are 3D printed but require access to a SLA printer. The electronics BoM is a pretty long list. The main camera, called CamPi, has a Raspberry Pi 3 with its companion camera module, a 2.8” TFT screen, a 10000 mAh power bank, a servo and a bunch of assorted parts. The GIF cartridge, called SnapPi, has its own Raspberry Pi Zero W, another 2.8” TFT screen, a 400 mAh LiPo and a boost charger. Several of the modules had to be trimmed in size and many unnecessary parts removed to make it all fit together.

One of the most interesting things about hacking is the difference between the vision we have at the beginning and the reality of we’ve built at the end. What began as a simple plan to build a night vision VR headset turned into a five-month adventure for [facelessloser] that culminated in this great-looking camera. He thought it would be easy, but almost every aspect presented some kind of challenge. The important thing is that he kept at it.
One of the major issues [facelessloser] encountered was power. He found that the Pi (Zero W), the screen, and the IR LEDs draw between 1.5 and 2A altogether. He was able to solve this one by using the charging board from a 2A power bank paired with a 1200mAh Li-Po built for the high draw required by vaping. If not for space issues, he might have used a 18650 or two.

This is an interesting development for media users and machine learning hackers: [doe300] has implemented OpenCL on the Raspberry Pi 3 Model B+called VCFCL That’s big news because the Pi 3+ has a Graphics Processing Unit (GPU) built into the processor that has been generally underutilized. The VideoCore IV GPU is built into the Broadcom BCM2837B0 and is surprisingly capable for a low-power chip. Although this GPU is well documented, it hasn’t been used that widely because you have to code specifically for this class of GPU. Adding in support for a high-level framework like OpenCL will make it much easier to run and adapt existing packages.
This OpenCL is the end result of a masters these by Daniel Steadelmann at Nurenberg Tech, and this implementation supports the embedded profile for OpenCL 1.2.

Capture Video From the Past with This Raspberry Pi Camera Rig

Johan Link, however, has an innovative solution for this age-old problem with his “Film in the Past” device
Link’s rig hooks onto a normal baseball cap, and films continuously with a USB camera. A Raspberry Pi 3B takes in the video, and upon pressing a button, it saves the last seven seconds of video that it captured. So if you “missed” that amazing event, you’ve got seven seconds to remember to press the record button, storing it for sharing and review.

Create a High-Speed Raspberry Pi Camera for Just $6 Using Nothing But Software

No special equipment is involved in Elder’s design, which uses a Raspberry Pi 3 Model B and a V1 or V2 Pi camera (hence the $6).
The V1 camera that was tested uses the OV5647 image sensor, and the V2 camera tested uses the IMX219 sensor.
The setup process involves using Hermann Stamm-Wilbrandt’s modified version of raspiraw, specifically a fork of raspiraw, which captures RAW image frames and timestamp metadata from the camera sensor and ports it to the Raspberry Pi’s onboard memory.

and up to 1007 on the V2 camera can be achieved. Filming at these extremely high frame rates on a Raspberry Pi is much more challenging and involves more work than typical point and shoot photography.
The major limitation throughout this process is the speed at which memory can be copied and transmitted. Only 20-40 seconds of video can be recorded at a time due the memory exhaustion of the Raspberry Pi. Also limited is the resolution of the recording: On the $6 camera, a maximum of 640×64 resolution can be recorded due to limitations on memory bandwidth.
