  • The “Zero” shown by Arduino.cc a year ago is different from the “Zero Pro R3” being shown by Arduino.org this year. The differences that I see are:

    The Arduino.cc Zero is a darker shade of blue and the silkscreen on the back says “MADE IN EU”, also it has 3 electrolytic caps, one located near the power connector.

    The Arduino.org Zero Pro R3 is the traditional Arduino Teal, says “MADE IN ITALY” and has the map of Italy, and does not have the 3rd electrolytic.

    From the pictures it looks like there are some minor differences in layout and routing. Both boards seem to have the Atmel debug chip.

    In my opinion the Zero Pro R3 is overpriced and without massive community software support its future is unknown. I would suggest using the Teensy 3.1 because the price is lower, it will take 5 volt digital inputs without blowing, and it has software support.

  • I understand the preference to omit supplier information, business flexibility, second source, and all that.

    However in this circumstance the ethical thing to do for your community should be to provide this information. When the picture shows the back of the board saying “arduino.cc” your customers would be rightly distressed to receive a “arduino.org” board, or some overseas knock-off for that matter.

    Alternatively, you could indicate sourcing in the text, e.g., “licensed from Arduino LLC” or “generic”.

    This is a vote from a member of your community.

  • Thank you Nate for commenting on this.

    All that Google has shown us so far is “information”. It’s now up to the courts and jury to turn this into “facts”. I haven’t seen much from the other side of the battle, but ramping up hardware manufacturing takes capital and supply chain relationships can be problematic, so they will probably spin a good story. With appeals and lawsuits on both sides of the pond it could take years to settle down.

    We are moving into the ARM Cortex era, and SparkFun could help by offering a licensed “Redboard Zero”, if you can get the LLC group’s software support.

    Sparkfun should also help by indicating the manufacturer source of its Arduino boards, and using different SKUs for the different suppliers. A picture of a .cc board should not result in delivery of a .org board, truth in advertising and all.

    An alternative would be to just walk away from Arduino boards and go with a new generation of the Teensy, again the software is more important than the hardware.

    Just another rambling from this old man.

  • Makers have been around for a long time. Fueled by Government surplus from WWW2 and Korea. This movement spawned HeathKit, Eico, RadioShack, and other long gone companies. In the 50s, folks were using point-to-point wiring and vacuum tubes, and parts made in the USA. I built my first radio transmitter out of parts scavenged from an old B&W TV. (5U4 for Power supply, 6L6 for Amplifier).

    Some years later, the Z-80 and the S-100 bus gave the movement another jolt, with CP/M being the top software. This was followed by IBM PC and its clones, and Microsoft.

    Integrated circuits, offshore electronic manufacturing, and throw-away thinking slowed the movement, but now it’s come back. I don’t know how long it can last, we’re in for surface mount, fewer nanometers and whole systems on a single IC, encapsulated in plastic, with nothing to solder onto.

    Just a rambling from this old-timer.

  • Certainly such organization is vital in an area that is shared, such as a school or club.

    However, in a personal space not a showplace some slack might be in order. I can instantly locate the Jacobs Chuck wrench or any other tool that I bought 40 years ago, I use labeled shoeboxes for parts and have separate toolboxes for my most common tasks. Between my ears lies a marvelous card catalog.

    A (totally) clean desk is a sign of a diseased mind.

  • What capacity & class will this handle? Some SD readers only go up to 2GB, others max out at 32GB.

  • Overwhelming. I hope you guys are going to have some examples - a kit or a bill of materials or wishlist that I can just add to my cart. Some tutorials also I hope.

    On the downside, how come you don’t carry Makerbeam, Openbeam, or Microrax, something that would build 3-D printers and CNC?

  • How much current can this supply to each device and total? And if I plug it into a USB 3.0 host, will it provide more juice?

  • If you are concerned about FCC compliance, just get your Ham radio license. It’s an easy enough test and Morse code is no longer required. Then you can work comfortably under Part 97 rules, and add on a better antenna for the range.

  • A bit of discussion of solder itself might be worthwhile. I grew up with 60/40, gives me nice working time. 63/37 is the eutectic, freezes faster and has a little lower melting point. This new-fangled ROHS stuff takes more heat, doesn’t seem to flow as smoothly, and over time can grow little whiskers, I don’t like it but maybe I’ll come around.

No public wish lists :(
