While processing EEGs for some artificial intelligence based diagnostics, I created an approach that innovates visualation with a Power Spectral Density sliding window integrating several minutes of EEG in a simple 3D visual graph schematic head showing sensor data location. The simplest in Python is to read EEG files in the EDF+ format with pyEDFlib I then use signal.welch from scipy to compute the Power Spectral Density on a 10 second sliding window. Thus I am able to visualize as shown in the
Bismuth crystals
I was using Bismuth for its diamagnetic properties, but since I found the pyrolytic carbon I was left with a few pounds of Bismuth . So I decided to use it for another nice property of Bismuth which is its crystallization that builds structures

Simple diamagnetic levitation with pyrolytic carbon
Here are the details on the small device I created to achieve levitation of a small magnet using pyrolytic carbon. The explanation is located here on supermagnete with the links to the magnets I bought the pyrolytic carbon from both a UK site

Van de Graaf Generator
Here are some details on my Van De Graaf generator: It was built with a bench grinder engine with a Teflon bottom and Nylon top pulley. The ball is a garden stainless steel gazing ball and the belt is made of rubber. Here is the source 3D image for

Working offshore long time ago
Before my current company I was working offshore for Total oil company. Here are a few pictures. This is the picture of one of offshore rig I was working on. It was taken in the Suez gulf and the grey shade just above the sea horizon is the Sinai.
