  • That’s a lot of markup. You can buy all the parts in the small parts kit, in single unit quantities, for about $11 over at Tayda. And the Tayda stock is apparently not limited like it is here, you can get as many as you want.

  • Nice to see Redboard Edge was designed using KiCad; hopefully this is a new trend at Sparkfun. Thanks N.Poole!

  • Almost 60 percent don’t share at all; I suppose that 60 percent are non-millenials (joke).

    I don’t get it; would you ELI5 please?

  • What are those, machine screws in raw plastic? You do know Sparkfun sells the heat set inserts, right? Or just use sheet metal screws.

    For 3D CAD there’s also Cubify Invent, about $50, it has no limits and works well enough but it’s not well supported.

  • What other 3D printed devices do you recommend for helping you organize or build your projects?

    Instead of bitey alligator clips, try some soft jaw spring clamps. Here’s an example with a 3D printed base, Panavise #201, and flex pipe arrangement using the soft jaw clamps.

  • Using Reddit instead of the datasheet is a bad idea. There is not really an “interrupt buffer”; there are, however, event triggered interrupt flags for each peripheral which will pend until they are handled. So assuming interrupts A, B, and C are event triggered interrupts they will all be remembered and handled. Another type of interrupt is level interrupts, which will only trigger if interrupts are enabled at the time the interrupt signal is present; so a level interrupt will not be remembered and will not trigger if another interrupt is in progress.

  • it is advised you use the shortest length that will work for your project. I2C communication is susceptible to noise,

    Hey SparkX how about a nice Qwiic I2C bus terminator with a little bitty LTC4311 chip on it? Much better than pull-up resistors, those things can really clean up a noisy I2C bus.

  • You know it’s gonna be a good trick-or-treat house when they require you wear safety glasses and a helmet.

  • ESD safe to protect sensitive components

    Weller, why you have to be so bad?

    Anyway, when we used these for field repairs on live railroad equipment it actually was an advantage to have a soldering iron that isn’t grounded. But calling these ESD safe and suitable for “sensitive components” is a joke.

  • Needs a built in camera for juice selfies posted instantly to Facebook.
