If you’re an engineer starting a business, do you need to worry about your business’s brand? In a word: yes. You don’t need to make a big project out of it at the start. It can be as simple as... Continue reading

To those who make and have made our freedom, our successes, our failures, our petty arguments, our philosophical differences, our explorations, our livelihood, our great discoveries, our day to day accomplishments, our freedom... To those that make and have made... Continue reading

Current flows through a diode from the anode to the cathode - it will pass current only when the potential on the anode is greater than the potential on the cathode. This is mostly true, but not always. For the... Continue reading

Announcing our "We thank you" customer referral program. Screaming Circuits always appreciates it when a customer tells someone about us and that second person becomes a customer. We love helping engineers get their projects finished, and the more people that... Continue reading

STEM (Science, Technology, Engineering, and Math) careers are getting a lot of press these days. They are important for global competitiveness and the general advancement of human-kind. STEM is also one of the few job markets (especially the “engineering” component)... Continue reading

I tend to get quite excitable when new, smaller, components come along. The smaller, the better. While, I haven't yet seen it up close and personal, I've seen the announcement and datasheet for a new SoC (System on Chip), with... 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

Not long ago (No Need To Waste Parts), I wrote about the use of tiny cut strips here at Screaming Circuits. That's good information, but only part of the story. (When has anything ever been the whole story???). There may... Continue reading

I fell into one of my own favorite traps last week: the dreaded LED footprint mess. I designed a board based on the Microchip PIC32 - it's a ChipKIT Arduino-compatible board - that has a number of RGB LEDs. on... Continue reading

Every few years something new rears its head and changes everything. The old rules break, convention gets unconventional, storied institutions get shaken to the core. We call this, "Disruption." Automobiles disrupted the horse and buggy industry. Airplanes disrupted the passenger... Continue reading

How many times can the project manager come in and ask how the PC board design is doing? Why can’t management understand that it’s difficult to say how long it will take to do something that’s never been done before?... Continue reading

If you're attempting to cross the median of a busy four-lane highway, it's entirely possible that there's a Jersey Barrier in your way. In that particular setting, having something sturdy blocking your way is probably a good thing. On the... Continue reading

We love parts on reels. Who doesn't? But reels aren't always practical - and it's not just about cost. Cost is, of course, important, but there may be other factors to consider. Say, for example, you need 20 2.2K Ohm,... Continue reading

Manufacturing, especially small volume one-time-only builds (like a prototype) is hard. It's not wise for most people to actively seek out chaos, but that's what we do, and we do it wisely. That's what we've been doing since 2003. We... Continue reading

It's late. Do you know where your PC boards are? Let me rephrase that: Can unused PC boards be stored for future use? Yes, they can - if stored properly. Keep them wrapped up, or sealed in a bag. Anti-static... Continue reading

There's a lot of buzz floating around these days, about "Personal Manufacturing." Screaming Circuits has more than a decade of bringing personal manufacturing to engineers. We pretty much started the category in the electronics industry, so we're quite familiar -... Continue reading

My prior blog covered the Screaming Circuits Manufacturability Index. It's something I'll be using from time to time when discussing new components I run across. I've got a few examples to put the numbers into context. On the low side... Continue reading

Screaming Circuits Manufacturability Index Ranks the difficulty of assembling a component. Index is one to five, with one being easiest, and five being the most complex Sub index: a, b, c a: Not a challenge within the number rank b:... Continue reading

Every now and then, I write about ambiguity with diode marking; like here, here, or here. It's a pretty important subject to get right, but what does it have to do with Marco Polo, you ask? Well, that depends on... Continue reading

There are many reasons you shouldn’t use via in pad. It’s not good practice, and those via holes act like little capillary straws and suck solder off of the pad or the BGA. That said there are some applications that... Continue reading

By now, most of you have heard about the Internet of Things (IOT). If not, here's a quick summary: The Internet of Things is the concept of having pretty much everything connected to the Internet in some way shape or... Continue reading

Tired of all those small parts? Can't figure out how to route traces to all 1,900 balls on that hot new FPGA? If 0201 passives have you running scared and the possibility of 01005 parts coming soon has you on... Continue reading

Everyone knows which way current flows through a diode. Right? Of course they do. Diodes only allow current to flow in one direction. Well, sort of. In the case of your garden variety rectifier, barrier diode, or LED, that's true.... Continue reading

The continuing saga of the 0.4 mm pitch KL03 ARM microcontroller. If you haven't yet done so, read part I, and part II. Today, I have a look at the good, the bad, and the ugly - or more accurately,... Continue reading
