Recently, a team from the St. Vrain Innovation Center assembled its first custom PCB design with the help of SparkFun. This is the story behind their project and their experience.
Join us for part two of our in-depth look at testbed design at SparkFun. Here, we focus on the hardware design choices for our in-house testing tool, the Flying Jalapeno.
Join us as we give some insight into the progress made in SparkFun’s testbed design over the past eleven years, and an in-depth look at our most recent production testing tool, the Flying Jalapeno.
Let's talk the whats, whys and hows of how you end up with a red box at the end of the day.
We use 0603 SMD packages but the electronics world uses much smaller sized components.
The dropping cost of LED bulbs is accelerating. We compare a few brands to see how they are approaching design and lower cost manufacturing.
We've partnered with 14-year-old whiz kid Quin Etnyre to bring his first Kickstarter to life!
In honor of Manufacturing Day 2014 (Friday, October 3rd) - We take a look at how SparkFun puts a dozen or so new products on the website each week.
Few funding campaigns pull heartstrings while actually doing measurable good. Jerry, impressively, is doing both.
