[GreenKeys] New USB to current loop driver board

[Ralph Mowery]

It is not too bad to get started with the SMD now.  I started a few years ago. Biggest expense was about $ 200 for the Amscope stereo microscope.  Ebay has some hot air and small tipped soldering iron combination  stations for about $ 60 now.  Doubt they would hold up under heavy usage, but not bad for just an occasional home user.

Major requirement is a steady hand.

>The good parts are SMT-only now

 

But the bullet a couple years ago

 

For prototyping I assemble little breakout boards. Built a reflow oven out of a toaster oven. Many designs on the DIY sites.
