This Will Be A Useful Tool For makers Let’s Build

Ever make a circuit board?  I used to do it in high school.  It was not much fun really.  First you had to coat the boards with a special coating that was sensitive to UV light.  Then you had to make a transparency mask of your board.  You then exposed the board to transfer the circuit diagram to the board.  Now comes the nasty part.  You put the board into an acid bath to etch the board, removing the copper where you did not need it.  Dealing with the etchant was very messy.

Ben Heck has a couple of different methods here, but he’s still dealing with etchant.

Dealing with the etchant is just plain messy as the video makes pretty clear.  So if there’s anything that could get rid of that stuff it’s a very good idea.  This little gadget might just do the trick.

It looks more like a lab instrument than a tool, but if it does what it says I can see that it would be very useful in an electronics shop, especially for making sure that the black magic keeps the magic smoke in(EE talk, they can be weird).

    Magic Smoke runs everything. let the smoke out and it stops working.
    It’s not as pricey as I was first expecting, but sure to get cheaper as time goes by.

      and I forgot to mention one cannot ever get the smoke to go back into the smoke containers, no matter how hard you try
