The day arrived to finally put the Nemo Discovery Apparatus out into the wild! I lashed up the solar panel to my backpack and headed down to the river.   I can't help but laugh when I see this photo, the solar panel is borderline too big for a backpack, but it does put out the watts!   Putting the solar panel in the water was really just to validate the proof of concept. The pool noodle pontoons could drastically be improved for a long-term deployment.     Placing the ...

Finding Nemo - Power

Posted by scottiebabe Jul 28, 2021
Alongside the performance increases of the Raspberry Pi 4 over previous generations, comes an increased demand for electrical power. The RPI team recommend a USB-C power supply capable of an output current of 3A. So, the easiest way to get up and running with the RPI4 and camera kit is to purchase either: https://www.raspberrypi.org/products/type-c-power-supply/ (or equivalent) USB-C Power Bank   29-7860 is an affordable power bank with a 2A output that may be sufficient if you are not u ...
  Close-up photography with the Raspberry Pi HQ Camera  In the previous blog I ended up photographing the Moon with the adaptation of the view camera with a large telephoto using a Raspberry Pi HQ Camera and a Raspberry Pi 4B. Now we are going to try macro photography using a lens used to print 6x6 cm medium format negatives.   Full moon 2021-07-23 Spain with the Raspberry Pi High Quality Camera and a Schneider - Kreuznach Tele - Arton 1:5,5/270     Macro photograph ...

Finding Nemo - Camera

Posted by scottiebabe Jul 22, 2021
I want to start off by extending my gratitude to the Element14 Team for sending me such a lovely gift! Mounting the Camera  With the camera having the ubiquitous ¼”-20 thread mount that has been in use on film and digital cameras for a very long time, there are consequently a vast number of camera fixturing devices readily available (like a tripod).   For this project, I am going to use some bits and bobs from a 50-in-1 Action Camera Accessory Kit. Partly because I alrea ...

My intention is to make a circuit that can see the increase in brightness of a lightning strike and trigger a canon camera to photograph it before it fades.  I have partially succeeded in this several years ago, but need to look up my current circuit, describe it and see about improving it.  A list of needs: appropriate sensor arduino to control it camera interface protection from bad weather. Portable power.   john ...
Having satisfied myself that my serial JPEG camera was working I have now implemented a fully working system that will detect cats (or any other warm blooded object), take a snapshot using the serial JPEG camera and save the image to a microSD card for later analysis.   The circuit diagram is show below and consist of a Nano connected to a microSD card adapter using the SPI bus, a PIR detector connected to D6 of the Nano and the serial JPEG camera connected  via a software serial link ...

Neural style transfer Among the many applications a neural network can be applied to, there is an interesting field called Neural style transfer. This term refers to an algorithm that takes as input a content-image (e.g. a tortle), a style-image (e.g. artistic waves) and return the content of the content-image as if it was ‘painted’ using the artistic style of the style-image. This technique was initially proposed by Gatys et al in 2105 and the good things is that it does not require ...
