ARPM: Another Raspberry Pi Microscope


Dr H @ instructables.com build a Raspberry Pi based microscope using a WaveShare B-camera and plexiglass parts. He writes:

Based on the RPI camera and LEGO brick-based microscope I presented earlier ( A-Raspberry-Pi-camera-based-microscope-built-from- LEGO ) I have constructed a similar microscope build from Plexiglas parts. So you may build your microscope even w/o having a LEGO collection. What is missing so far is the adjustment gears of the LEGO version.

The maximum resolution is about 5 µm/pixel. On high resolution only a small area will be in focus and you will see an effect called chromatic abberation.

Below you will find a description of the device and the information required to build one on your own.

Pixy camera: detect the colour of the objects and track their position


By Boris Landoni @ open-electronics.org:

Here we present our first tests with the Pixy camera, a device capable of detecting the colour of the objects, and to track their position.

Until a short time ago, it was really difficult to develop applications able to take advantage of artificial vision algorithms, and most of all by using systems with limited hardware resources.

Luckily, however, things have changed now: in addition to the various open source frameworks that help developers to easily implement even the most complex algorithms, complete peripherals are spreading, be it for the hardware part (providing the acquisition of images coming from the outside world), or for the software part (able to analyze and read such images). With such peripherals it is possible to create applications provided with artificial vision, in a really simple way.

Inside the Intel RealSense Gesture Camera

STMicro resonant MEMs device inside intel realsense

by Sinjin Dixon-Warren @ chipworks.com:

The Intel® RealSense™ gesture camera represents another foray by Intel into the consumer products space. The camera has been incorporated into the Lenovo ThinkPad Yoga 15. Intel disclosed at IDF14 that the device is formed using three components: a conventional color CMOS image sensor camera, an infrared images sensor, an infrared light projector (the main focus of this article), plus an image processor. It can also incorporate a pair of microphones.

Raspberry Pi Compact Camera


by PiJuice @ instructables.com:

I’m so excited about this new project! A truly compact and portable Raspberry Pi Camera and it’s easy as anything to build!

I first thought about building a Raspberry Pi Camera after seeing the SnapPiCam instructable guide. This is a clever little project, which uses a LiPo battery to power a Raspberry Pi model A. But it got me thinking could I do something even more compact which is even simpler to build?

The real challenge is powering this little baby. Where the SnapPiCam is using a separate battery, converter and charging unit I’ve used the PiJuice. It’s basically an all in one battery module for the Raspberry Pi and it’s an ideal integrated power solution for a DIY Compact Camera.

I’ve also decided to use the Raspberry Pi a+ as it’s the cheapest and smallest available Raspberry Pi so it’ll fit nicely with PiJuice and make this camera supper compact!

See the details with an HD thermal imager


by Martin Rowe @ edn.com:

With today’s circuit components in ever–shrinking packages, finding an overheating component or a component damaged from heat during assembly can be a challenge. To help isolate those components, Fluke has introduced the TiX series of high-definition thermal imaging cameras.

Consisting of the models, the TiX series cameras have resolutions of 1024×768 and 640×480 pixels that display across the imager’s 5.6-in. display. That’s 3.1 million pixels and 1.2 million pixels, respectively, when using SuperResolution mode. The TiX imagers have a temperature range of -40°C to 2000°C (-40°F to 3632°F).

Selfiebot – Your personal photo companion

by Michael Wang & Jennifer Qian @ cornell.edu:

Imagine you are traveling the beautiful Icelandic countryside. You and your significant other have found the perfect place for a picture, and you both look stunning that day. But there is no one around to take it for you! You go for the selfie, but your arm just isn’t long enough to do justice to the landscape.

Introducing the Selfiebot! This robot is designed to track faces and take pictures of you and your friends, completely autonomously. The system allows the user to set a number of parameters specifying image properties, centering properties, and photo taking parameters. We used OpenCV running on a laptop computer for image processing and facial detection, and relayed scanning and centering commands to the robot via serial communication to the ATmega 1284 microcontroller.

OV7670 Camera Module DIY Guide


This camera module can perform image processing such as AWB (auto white balance), AE (automatic exposure) and AGC (automatic gain control), for the video signal coming from CMOS sensor. What’s more, in fusion of other advanced technology such as image enhancement processing under low illumination, and image noise intelligent forecast and suppress, this module would output high quality digital video signals by standard CCIR656 interface. OV7670 built-in JPEG decoder supported reatime encoding for collected image, and external controller can easily read the M – JPEG video streams, achieving the camera design of double stream. OV7670 supported motion detection and OSD display function of screen characters and pattern overlay, capable of self-defining detection area and sensitivity.

ALCAM-OEM – Serial camera module


Serial camera module that captures time-lapse and stop-motion videos plus images to uSD card. Use with any micro like mbed and Arduino.

ALCAM allows any embedded system with a serial interface (UART, SPI or I2C) to capture JPG/BMP images and also to record them right onto an SD card. Also, ALCAM gives you the ability to create time-lapse and stop-motion AVI videos and save them directly to the SD card. All done through a set of simple and well documented serial commands. ALCAM can also capture images and videos though a special pin, without the need to send any commands.

Flir Lepton Thermal Imaging Sensor + Gameduino 2


by theresistornetwork.com:

I recently got my hands on a pair of Flir Lepton thermal imaging sensors and have spent the last week bringing them online in my spare time. These are absolutely incredible devices that I believe will pave the way to consumer devices incorporating thermal imaging cameras. The footprint of the camera module (and optical assembly) is about the size of a dime. The resolution is 80×60 at 14bpp which is remarkable despite sounding low.
