Meet our newest Creative Technologist Mariah and learn all about what brought her here to SparkFun!
Although the 3D printer seems to get the spotlight most of the time, people are making some very interesting projects where the laser cutter takes the lead role.
Wherein I take a break from pushing pixels around to wire my biker scout trooper helmet for sound.
Courtesy of Terrence Fagan, Engineering Chair at Central Piedmont Community College. Terrence has done a lot of great work in engineering education and outreach in his community. He had the opportunity to attend the Fab10 Symposium in Barcelona last July. When he started telling me about his experience there, I felt it was a must for a blog post.
The story goes that George Antheil was madly in love with Hedy Lamarr and this was an attempt to gain her interest. There are no documents…
I know a guy who is a big "fan" of IoT, even though he's not all that technical. His "day job" is as a business attorney, so he can afford a…
That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
