Welcome on the website of Alexander C. Frank, aka Ajarn Changpuak !
This website offers a lot of calculation tools for electronic circuits as well as some electronic projects like power supplies or rf related stuff
like antennas or filters.
Also a large amount of pictures and information about Thailand and Thai Customs has been researched and made available.
Last but not least a collection of nice recipes of tasty food is presented. Some of them have been invented by us and some are
copied from good chefs. (German only)
