Like always, feedback systems provide more accuracy and reliability to the system, but in here I omit current and voltage (or altogether resistance) variations of the NiCr wire because it need more components and space :(. In here my plan in is to make some low cost, less complex and customizable (adjustable) NiCr wire base cutter.Dilshan Jayakodyhttps://www.blogger.com/profile/04879320865396389381noreply@blogger.comtag:blogger.com,1999:blog-1807662398197986478.post-3386909735325428232013-04-15T21:27:36.957+05:302013-04-15T21:27:36.957+05:30It would be cool if it measured current and voltag...It would be cool if it measured current and voltage drop across the nichrome wire and was a constant power controller... This way it will account for the cooling of the wire as it melts the foam. Think of it as trying to keep a constant resistance of just the wire, since the wire has a temp. coefficient. Something I've been meaning to try for a while now.Anonymousnoreply@blogger.com
