hi i'm fish and i got this idea from a friend of mine, a somewhat down converter for a 30W soldering iron to 15W. temperature controlled stations costs too much for me as i am only starting in this field. the original idea was to insert a diode between one of the conductors in the heating element. my friend suggested that maybe we can do a switchbox with LED indicators instead to preserve the soldering iron.
here is what we did so far...
**broken link removed**
-this is for a 220 AC voltage.
-the diode is the 1N4004
-using a DPDT on/off/on switch to bypass the diode on high position
-we tried resistors with values at 3.3K but it got fried.
-what resistor values will we use for this circuit to work?
-is it gonna work to begin with?
-what do you think?
i'm new to these so please bear with me a little.
