The global chip shortage has not made the life of the electronic design engineer an easy one, as products have been designed around whatever parts are available rather than the …read more Continue reading The Chip Shortage Leads To The Strangest Things
“The prototype was $12 in parts, so I’ll sell it for $15.” That is your recipe for disaster, and why so many Kickstarter projects fail. The Bill of Materials (BOM) is just a subset of the Cost of Goods Sold (COGS), and if you aren’t selling your product for more than your COGS, you will lose money and go out of business.
We’ve all been there; we throw together a project using parts we have laying around, and in our writeup we list the major components and their price. We ignore all the little bits of wire and screws and …read more
KiCAD remains a popular tool for designing PCBs and other circuits, and with good reason: it’s versatile and it’s got pretty much everything needed to build any type of circuit board you’d want. It also comes with a pretty steep learning curve, though, and [Jeff] was especially frustrated with the bill of materials (BOM) features in KiCAD. After applying some Python and Kivy, [Jeff] now has a BOM manager that makes up for some of KiCAD’s shortcomings.
Currently, the tool handles schematic import, like-component consolidation, and a user-managed parts database that can be used to store and retrieve commonly used …read more
