As you get into digital fabrication and restore, one of many first stuff you notice is how onerous it may be to carry a PCB nonetheless whilst you work on it. Securing them is tough because of their very nature: they’re usually bizarre shapes, fairly fragile, and naturally must be electrically remoted. If you don’t thoughts spending the cash, and have the time to attend on it getting delivered, you possibly can order some good purpose-built programs for holding PCBs on-line. But what in case you want one thing quick and low-cost?
[Paul Bryson] might need the answer for you. On his weblog he’s documented how a visit to the greenback retailer and a few elements from the junk bin allowed him to create a practical system for holding multiple PCBs of various shapes and sizes. The most unique ingredient of the construct listed here are the hexagonal standoffs; and in case you haven’t already salvaged a bunch of these from a curbside laptop, he even offers the Mouser hyperlink the place you should purchase them new for a number of cents every.
Each particular person stanchion of the system is made up of a three/four″ spherical magnet with a hex standoff glued to the highest. Over the standoff, [Paul] slipped a rubber grommet which supplies a pleasant non-conductive slot to place the sting of the PCB in. Otherwise, a second hex standoff screwed into the primary can be utilized to clamp down on the board. Adjusting the peak is so simple as including a pair extra magnets to the stack.
Of course, magnets want one thing steel to stay on. For that, [Paul] bought some metal pie pans and matching rack from the greenback retailer. The spherical pans are straightforward to deal with and provides him loads of floor space, and the rack makes for an exceptionally handy storage unit for all of the elements. The conductivity of the pans is perhaps a priority, however nothing the appliance of a rubberized spray coating couldn’t repair.
We’ve covered similar systems before, however this one actually appears to be like to take the highest spot by way of economics. The solely factor that may be cheaper could be a few feet of PLA filament and a rubber band.
