AKA, A second post on the Raspberry Pi Zero. It's been two months since the release of the $5.00 Raspberry Pi Zero, and I still haven't been able to buy any. As I discussed in my prior blog about it,... Continue reading

The weather's just fine out here in Oregon. Well, that depends on your exact definition of "fine." It's raining out here and I'm not sure it will ever stop. But that's not the point. Parts of the East Coast are... Continue reading

Much of marketing can be summed up with the word “communication.” It's communicating about a product or service, about wants and needs, or the past and the future. Good marketeers take this to heart and work hard to understand their... 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

What could you. would you do with a computer that costs $5.00? First, let me explain a bit. The Raspberry Pi, if you don't know, is a small, inexpensive single board computer designed by the non-profit Raspberry Pi foundation in... Continue reading

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

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
