This blog is about country life of myself; raising kitchen garden, star gazing, studying math., HAM Radio, homebrewing electronics. You can visit my other blog "Teaching with Fun" about Semiconductor Design. Postings on this blog are written in Korean. Foreign visitors can read through Google's translation service. AI translation is sometines IDIOT. ;-)
