(expect more flippant answers like the one above - the need that some people have to chronicle their lives to complete strangers over the Internet is simply bizarre - get a real life and delete all those TwitSpaceFace accounts, ok? Unless, of course, you just like your potential employer being able to get answers to all those questions which it would be illegal for them to put on an employment application.)

  • I sense a serious need for cheap LED flashlights powered by standard camera batteries so that outdoor photographers can carry more than three batteries per camera (one in, two out). “Yes sir, I have a pathological fear of power failures and the dark, so I carry 10 flashlights everywhere I go, and yes, I like using four different kinds of expensive batteries to run my flashlights - its a reliability strategy.”

    And thanks, I would appreciate a modest royalty for giving you a new product idea ; ) .

  • I am a very long time customer, and usually a fan, but: This is the most clueless, right hand bigoted location for a trackpad EVER.

    Who designed this abortion of a layout? Did they not realize that there was a reason that essentially every other laptop device on the planet has the trackpad in the center?

    Maybe they were trying for ERR-gonomics?

    Sigh, I was briefly excited and ready to order until I noticed the glaring flaw.

  • Glad to see the addition of isolation from the frame. Carbide needs to do the same thing on their board that they are shipping with the Shapeoko 3 machines. Instead, they have added an embarrassingly kludgey oversize filter capacitor. I suspect it would have been adequate simply to have not shared the controller’s ground with that of the router motor/spindle, although I admit that I have not tested this hypothesis. Perhaps they did, and I am wrong.

    But there are several things that don’t thrill me about their controller, so I am considering switching to this one. It probably means that I can’t use their software any more, but I think I can live with that.

  • All that aside, and not meaning to criticize you or the Sherline, a Bridgeport Knee Mill and a Sherline column micro-mill have a relationship that is similar to that of a Kenworth and the new Mini Cooper Tiny Truck . Both are kind of neat, and have similar functions, but are in totally different classes. Still, as the owner of various Chinese machine tools, I’m not in a position to be throwing rocks at anybody ; ) . Regards.

  • Chamnit, The Sherline is a knee mill?!? I think you must have Sherline confused with Bridgeport. Sherline does not make anything close to a knee (C frame) mill, which would typically have a mass which is probably 50 times that of the diminutive Sherline bench-top column micro-mill. Knee mills have an X-Y table which can be moved up and down on an adjustable knee, and they are big - about the biggest mill you would expect to see in even a very well equipped home shop.

  • You’ll get a lot more speeding tickets, and the paint will fade if you park it in the sun. : )

  • Hmm, very interesting. If only Sparkfun accepted BTC, Santa Claus' official currency (one area where Adafruit has an edge).

    Questions: What sort of accuracy and repeatability can we expect? I realize that the spindle is involved in that equation, so any specs on the two different routers (DeWalt/Porter) ? Finally, given that this is Sparkfun, what kind of pitch have you been able to reliably obtain milling PCBs ? Do you have a recommended bit for this application?

    Christmas elves want to know ; )

  • I understand the potential value of being able to push updates, and I’m certainly not casting aspersions on this hardware. But I don’t see any elegance in the move to a cloud based dev platform. None of the functionality which you are pointing to requires that the development environment itself be in the cloud, and it is to that largely pointless hobbling I aver an objection.

    While I’m not going to cut off my nose to spite my face when the cloud is the answer, privacy and security concerns make me leery of cloud solutions. In the case of moving the development environment to the cloud, my concerns are somewhat less about privacy and security, and more about adding non-useful layers to my work environment. I spent much of this past Monday without Internet access, but the outage had no impact on my ability to work. That is just the way I like it, so “no thanks” to cloud coding. ; )

    P.S. I very rarely use Arduino of any color board.

  • This is clearly a great program, and I don’t want to throw stones, but a learning opportunity is apparently being missed. Part of being a good engineer or scientist is communicating about your work clearly and effectively. It would be great if they could include a technical writing component so that the kids could overcome the tendency to use statements like, “This was the first year that we done[sic] it.”

    I spent several demanding but delightful (volunteer) years running a technology exploration program at an experiential K through 12 school, and we found that this sort of multi-discipline approach was very effective. Technology is fun for both the teacher and the student. In the midst of that fun you can slip in a fair bit of “boring” subjects like history, math, and grammar without the kids even realizing that they are also enjoying stuff they normally complain about taking. Technology is great, and I have spent a lifetime involved with tech and science, but we owe it to young people to help them become well rounded and fully functional people who can achieve their full potential. Properly applied, technology can be a great means to that end.

    Kudos to Sparkfun and all the others who make technology accessible to those who haven’t got the resources to “roll their own”. You do a lot to make these sorts of activities possible.

  • Let me second Member #679961’s objection to cloud based software development. It simply adds another layer of things to encumber the development process with no discernible benefit. I don’t get the fascination some people seem to have with moving essentially local tasks off of their computer and into the cloud. It is a bit like falling so in love with using wrenches that you start using them to drive nails. /rant mode off
