Mini-Vise
Hold anything mount
I have been using this little vise ($27) since my interest in electronics was sparked by Make and Hackaday.com. Before I was just using the standard two-arm alligator-clip and magnifying glass holder from Xacto.
The Panavise is much more stable, adjustable and appropriate for breadboard soldering. It has the little grooves on the arms that your board can slip right into and a nice heavy base which means it doesn’t need to be attached to a table if you like to move where you work around a bit. I’ve built several kits and designs of my own using this little vise. I am comfortable knowing *before* I start any project that this is one problem I am not going to have to solve.
