Screaming Circuits: Engineer stories

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

CAD This or CAD That

I use Eagle CAD a lot. I can get away with the "Light" version, because the designs I create are small and non-commercial. I do use them sometimes to illustrate points here on my blog, but I think that still... Read more

Grounded in Reality?

Looking back, I think I could have done a few things different. For example, I don't really need a separate power-on LED. I could either just not populate it, or rev the schematic a little to make it a software... Read more

That Final Check...

I'm not talking about the final check that you get from an employer laying you off due to outsourcing. That's a bummer of a final check. The final check I'm talking about is a good thing. It always pays to... Read more

Twitter, What is it Good For? Absolutely 555contest

I follow a few people on Twitter. A few people follow me on Twitter. A number of web sites have engaged their readers in debates about the usefulness of Twitter (and other social media) to engineers. In general, these debates... Read more

All Leadless

It wasn't too terribly long ago that just about any design could still be built all thru-hole. Okay, maybe it was a little longer ago than that. Once the big CPU chips stopped showing up in PGA (pin grid array),... Read more

How Fast Is Fast? I Mean, Really?

We talk a lot about speed here at Screaming Circuits. Back in 2003, one of the main reasons our parent company started us up was because their customers were telling them that they needed prototypes faster. So, I know that... Read more

Reminders and Stress

Yesterday, I wrote about how much faster we can get things done in the prototype world than we could back when many of us were starting our careers. I mentioned that the decrease in time from weeks to days needed... Read more

Reminders are Good Sometimes

I was just recently reading an article on another website that caused me to reflect a bit on where we've been and how far we've come in this industry. The article covered a design engineer's experience with modding a board... Read more

mbed Development - USB Programming Forever

I'm still fiddling with my mbed. Although, I haven't put it to real use yet. I've got some ideas, but I just don't have the time these days. One of the nice things about its programming system is that if... Read more

LED Lighting Assembly

When I first attached a 280 ohm resistor in series with a 5mm red LED, the word on the street was that LEDs were low power, forever-lasting devices that would just about completely replace incandescent bulbs for simple binary indicators.... Read more
