Be sure to practice on some scrap electronics. Quick tip, you can use a tantalum capacitor to see if you get things too hot. They will darken or turn brown if they get too hot. A good visual aid when dialing in your hot air temps.
@ecuadorche The new version uses direct fets. Direct fets work better in high current applications. They are a little harder to solder by hand which is why the original used the common style of mosfet.
@JTAG Yeah, it will be a little while. Vedder stated he will be doing some rerouting of the ki-cad files but will be ordering parts within a week. Don't hate on us ki-cad users Plus this is not a completely new design, I highly doubt it will take Vedder that long to work it out.
