Quad Fever!

Quadcopter fever has blown through SparkFun. I’m not sure where it started, but suddenly, it seems like everybody is flying around a cheap little quadcopter. The most popular model around here is the Estes Proto-X, a mere snip at $35-45US. It’s small size makes it nice for goofing off…

Enginursday - Three Childhood Mysteries Electrical Engineering Solved for Me

When I was a kid I was (in retrospect, unsurprisingly) a “why/how” kid. That’s not uncommon; what is uncommon is how long it lasted. I’ll let you know when I grow out of it. Throughout my childhood, there were a number of questions that I posed which, frankly, none of the…

PCB Basics

What exactly IS a PCB?
  • Product PRT-12084 | yesterday

    I’m looking at this to see if I can make this better. The problem lies in making something that will work for a lot of people; without knowing what they’re all doing, you kind of have to make a best-case assumption.

  • News - Quad Fever! | yesterday

    I’m unsure; the transmitter at least is just an epoxied die-on-board assembly.

  • Product DEV-11190 | about 5 days ago

    Your best bet is probably some kind of serial LCD; we carry a variety of those. You can use a software serial port on one of the unused pins.

  • Product PRT-12084 | about 5 days ago

    It can, but you’d need to make some serious changes to the values of various components in the circuit. I don’t recall whether the topology is the same for multiple cells.

    One thing you may consider is putting one of these across each cell in the stack. So long as the solar cells are isolated from one another, you should be fine.

  • Product PRT-12084 | about 5 days ago

    Hm. I hadn’t considered using this with a super cap. It might work, but I’d add a small series resistor. If I give it a try, I’ll post results, although it’ll never be nearly 300F.

  • Product PRT-12084 | about 5 days ago

    That’s true, and it’s covered (in bold text) in the hook-up guide.

  • Product PRT-12084 | about 5 days ago

    Ba dum-bum.

  • Product BOB-11189 | about a week ago

    Yes, the voltage range is 3V-5.5V.

  • Product SEN-12617 | about a week ago

    Check out the assembly guide, specifically this page, for more details on mounting.

  • Product ROB-12097 | about 2 weeks ago

    Not much; some of the labels, and the addition of a button on D12. Also, at some point since the first version, I fixed the power switching circuitry that disconnects power from the I/O headers labeled “Servo”. I’m not saying that was changed in this version, just that it has changed.
