Still waiting on the daybreak, its shadows in my mind
A large format XY scanning hyperspectral camera A hyperspectral camera captures spectral data for each pixel. To create a version of a hyperspectral camera I made use of a 200um fibre optic cable attached to a spectrometer which is moved in both the X and Y axis behind a large format camera lens. I make [ ]
I wanted to create a 3D printed mount to attach Canon EF lenses to a P8079HP night vision tube. All models where printed using a Bambu Lab A1 mini FDM printer. All prints where made using a 0.20mm layer height with a 0.40mm nozzle. As far as I understand the P8079HP uses 3 image intensifiers [ ]
Intro I wanted to build a CNC microscope using off the shelf parts in order to attempt image fairly large objects such leaves, CD-ROMs etc. to reveal detail that can t be seen with the naked eye. This required a metallurgical style microscope, which shines light through a microscope objective, onto a sample. Initial attempt I [ ]
Using visual cryptography I wanted to created two simple metal keyrings that when overlaid displayed some text. See https://en.wikipedia.org/wiki/Visual_cryptography and the original paper https://link.springer.com/chapter/10.1007/BFb0053419 by Naor and Shamir for more information. They make use of 6 shares (6, 2 2 patterns), currently I m only making use of the two diagonal shares. To do this I…
I recently came across a really fascinating video https://www.youtube.com/watch?v=tYFLze9VwB0 where they make use of a micro laser projector to generate a speckle pattern on a surface and then photograph it with a DSLR. They then simply touch a surface with their hand/finger and then take a photo of the speckle pattern again after the [ ]
Unfortunately I must have fermented too long in the first attempt as the beans became mouldy. Attempt 2 Fermented for only 1 day 19 hours Used a dehydrator on full for around 4 hours, this was probably too hot in retrospect, next time put beans in a higher shelf and use a low temperature Roasted [ ]
The aim of this project was to display a colour image on a black and white monitor, by overlaying an acetate bayer filter (inkjet printed) over the monitor and mosaicing a colour image. I obtained an Eizo B W monitor from ebay, which I was intending for use viewing B W photos and was curious if I [ ]
I created a PMOD module PCB using KiCAD, that enables connecting WS2812B lighting strips to an FPGA board with a PMOD interface. The board was assembled by JLCPCB. This is my first project using an FPGA, I plan to soon implement an SPI interface with the FPGA, to accept colour pixels via SPI from a [ ]
The idea of this project is to image the refractometer output, then convert the position of the blue line, to a digital reading, using image processing. The idea is to measure the brix of wort during mash and sparging, so that sparging can be stopped around 1.010 SG, to avoid tannins. It was necessary to [ ]
Acoustic Cryptanalysis Acoustic cryptanalysis is a type of side channel attack that exploits sounds emitted by computers or other devices Wavecatcher is a simple PCB that makes use of a MEMS ultrasound microphone, in order to capture audio to around 80kHz, with the goalof finding interesting ultrasound sources and playing with exfiltrating data from SMPSs [ ]
