  • I have to +1 this. I started with Eagle because that is what SF promotes (and provides tutorials for!). I really appreciate the support they provided when I was starting out, but now that I use KiCad (Had to switch for commercial application) I wish I had started there. No restrictions on boards, open source, and has the option to use a single schematic with multiple board layouts (big seller for me). So you can design an Arduino clone in a schematic, and then choose to make both a SMD and Through Hole version just by selecting different footprints! I used this recently with a power board I designed, started with TO-220 transistors and switched to SMD D2Pak with the same initial schematic.

  • Hi Sparkfun, both connectors are polarized but I don’t see which pin connects to which. Cool cable, but please let us which pin on the JST corresponds to the pin on the barrel jack. Perhaps a diagram would be useful?

  • I’m curious how heatsinking would work for this board. Would the heatsink be attached to the plastic case of the transistors (on the backside of the board)? If so, I didn’t think much heat was dissipated through the plastic, I thought it was mostly through the transistor tab?

  • And a young Stephan Colbert thought to himself, “Hooo, hooo, who will be the greatest satirical newscaster? Yooo, yoo, you!”

  • One more bug, prices on this page (in US) show up with 5 digit cents: https://www.sparkfun.com/categories/242/

  • Great Video! Quick (hopefully) question. I’m trying to sample a DC motor voltage, and it’s really noisy (brush noise, etc.). Is there a good way to do this with a standard arduino ADC (maybe an RC filter)? I’ve seen some stand alone ADC chips, are these worthwile, or should Arduino ADC function basically the same way? Thanks a ton!

  • Anyone know the wire gauge? 22 AWG?

  • I think you’re really missing the boat here. Your tanks and planes example is so far from a good comparison. I’m really baffled you view work as being “destroyed” (the point I think you’re trying to make with the tanks) once other people are allowed to see it free of cost.

    To address your final point, yes, it is still important to cite work that we (and others) have done. How does having this information freely available make this different? Do you think things only have value if someone continues to pay for them?

  • But academic research has already been bought and paid for, much of the time by the public. Grant’s from NSF, NIH etc fund that research (in the USA). The only one who makes money from the papers are the paper publishers.

    As a grad student, I actually have to pay the conferences and journals to publish my work (a requirement of being a grad student is to publish or GTFO). So no, the researchers who do the work were not the ones who lost out on money here, they still got paid for the work, long before it was published.

  • I think there is a button.
