One of the handy aspects of getting boards assembled at Screaming Circuits is that we don't require fiducial marks for standard process boards. I would say that we build far more boards without fiducials than with. That's cool, but there... Continue reading

Half a decade ago, back in January 2010, I wrote up a list of predictions for the end of the decade. You can read that list here. It's still 2015, so I can plausibly say that we're half way there,... Continue reading

The two most common causes of delay in small volume manufacturing here at Screaming Circuits (and presumably, others like us) are component availability, and footprint mismatches. We don't substitute parts without your approval for a number of reasons. I've written... Continue reading

In the digital world, we're accustomed to everything being driven by the absolute 1 or 0. You can also add in Tri-stated too, but that doesn't really count for computational or conditional logic. Analog allows for degrees of data, but... Continue reading
