Trust me when I tell you your friends $20 pen is not on the same level as a device like this. You cannot even get the parts from china wholesale for $20 with something like this. The genuine batteries alone are going to run you that much. You can probably get all of the stuff I listed above shipped for under $100.
As has been mentioned before, there are room for both types of devices to co-exist, but what we are talking about here is a real battery powered nail. Those other pens are good for certain circumstances, but can't replace a true dab to the head.
When you have a device like this, there are no "safety" electronics involved at all. When you push the button, you are basically making contact directly with the battery to heat up your coils. The only limitations on your power output are the type of coil you twist and the type of battery you use which is why it works well for our purposes.
I need to make one of these for around the house. Are you saying youtube videos will show me everything to do it or is there a tutorial somewhere you have seen?
Any other tools or supplies other than the main 4 parts mentioned? Special solder or the like?
