DIY Hand Sanitizer Calculator

The World Health Organization published a guide on how to produce an effective hand sanitizer when a commercial one is not available. While they discourage home production, with the COVID-19 pandemics in action, finding hand sanitizer has become challenging everywhere in the world.

I’ve made a google sheet for the calculation of the quantities needed for home production using the WHO recipe. You will need:

SimpleElastix precompiled Python modules

I have produced a number of precompiled SimpleElastix Python modules. As it is a pain to recompile it every time, I publish them here in case someone finds it useful. Let me know at if you need more.

Use easy_install to install the .egg files and pip to install the .whl files.

Newer modules are on PyPI maintained by myself! Install them with

pip install SimpleITK-SimpleElastix

All the modules are compiled for the x86_64 architecture.


I have created a divelog page that I distribute to my students. It is based on my experience and it is meant to contain all the important information that an Open Water/Advanced diver should include while describing their dives. I am releasing it as open source, it is saved in svg format, which you can edit with Inkscape.

I prepared it in two versions: the standard “Divelog” format (188x118mm) and the standard “Personal Organizer” format (170x95mm). If you prepare other formats and you would like to see them on this page, or if you make any improvement that you would like to share, feel free to contact me..

Below, you can see the previews of the divelog pages, with links to the svg files and links to pdf files that can be printed on A4 paper double-sided (long edge binding) to have nice double-sided pages ready to be put into your divelog!
