Currently I'm working on a device to electrocute home insects like cockroaches, progress is small because they are smarter than I thought, but that's a different story. For that project I had to find a source of sufficient high voltage and output power....
Conway's Game of Life - online JavaScript version
in fractal, javascript, mathematic, programming / with 2 comments /
Game of life is an example of a system with very simple rules but unpredictable state in the long term.
Each square represents a living space available for a single cell. If there aren't enough cells in the neighborhood, the space is empty, if the cell was present there it dies from loneliness. If...
Fractal way of map generation by using diamond-square algorithm
in fractal, javascript, mathematic, programming / with 4 comments /
Diamond-square algorithm is a simple way to generate maps by using fractal approach. The idea is to generate recursively a point based on the values of its neighbors and an additional fluctuation.
The main disadvantage is that landscapes aren't realistic and there exist visible edges created during...

Bifurcation diagram of the logistic map [online version]
in fractal, javascript, mathematic, programming / with No comments /
One of the reasons why mathematics is so amazing is that even a simple at first glance concepts have interesting behaviors and features. I think that the bifurcation diagram of the logistic map is a great example.
The logistic map is given by the equitation:
xn+1 = rxn(1 - xn), x0 < 1, r ∈ (0,4]
Below...
5V/400V DC/DC converter
in electronic engineering, high voltage / with 2 comments /
A small and cheap 5V/400V DC/DC converter can be useful in many DIY projects, e.g Geiger–Müller counters. I will present here one of such DC/DC converter based on popular MC34063 chip in step-up configuration.
One big limitation of this device is...
