Do you want to help financially?

Why donations?

alvistec.blogspot.com, and Space Alvistec is this beautiful project created and maintained by a willful man - I do this work because I love him, not for money only, I have spent hours and hours on the pc writing posts and recording videos. That's not all, although lately I have been posting some sales in mercadolibre.com.co this is not enough to finance my project because I work occasionally and sales are also occasional. Google hosts the content for us "for free", and the YouTube adsense has helped me a bit, however, keeping the pages available, updated and online involves me in costs, for example: Internet service, domain registry, energy, a cup of Colombian coffee… all this is not free.
Thank you for your cooperation in helping me keep this project online!
