    What’s the color temperature of these? Are they warm or cold white?

    Two processors is no good. If they don’t match, which one is wrong? You need three, so two will match and one will be different. But I suspect Robert is right about it not being likely to come up. If he does encounter that much radiation, he’ll have other worries than his logger.

    I think you’re underestimating the amount of effort just slapping things together would be if you want to come up with something so easy to use. Yes, something like this could be made cheaply using other parts put together, but I think it would be a significant project on its own. If you are working on a project and need an interface, starting another project to create the interface may not always be desirable. Before long you may find yourself in Tibet, shaving a Yak.

    On the other hand, I do find myself hesitating to spend 2-4 times as much on an interface compared to what I’m spending on the actual computer. But that’s more because the Arduinos and Raspberry Pi are so darned cheap. Any sort of display for a RaspPi costs more than the RaspPi. Heck, even connecting a Pi to a non-HDMI monitor can cost more for an HDMI->DVI converter than the Pi costs (if you don’t shop around). I find this to be a difficult psychological barrier to cross. The 4D screens seem like a reasonable value for what they offer, if only the devices they connect to weren’t so much less expensive.

    Spending $180 for a computer plus display doesn’t sound bad, but $35 for a computer and $145 for the display just seems wrong. But that’s not 4D or Sparkfun’s fault, it’s all in my head (and I suspect I’m not the only one).

    Nate’s clever plan for fitting more engineers into the existing office space seems to be working so far.

    Yeah, that thin dry air causes problems for baseballs, too.

    For those who don’t want to search the datasheet, the max range is 5 meters, and it returns the distance to the closest target it sees.

    I’m sorry to see it go away, but I agree with your conclusions. Better safe than sorry. Thanks for the Free Days that you had. I guess we’ll just have to settle for your great customer service, free stuff like tutorials, awesome site with loads of info about each product, and your commitment to educating future generations. I think I can live with that. ;)

    How much force does it take to press it in? I’m thinking it looks pretty good for use under a pedal for my dogs to push as part of a game I’m making for them. Also, the dimensional drawing doesn’t indicate how high the button is.

    DB9 and PS/2??? What century is this? I’m not sure I have a computer with either of those connectors. I might have an old desktop, but it wants a mouse or keyboard in its PS/2 connectors.

  • Tutorial - Elevator TARDIS | about 2 years ago

    Regarding the final word of caution, I was doing some testing of XBee ranges from a conference room where I work (Google) and had a control box with an XBee in the room and carried a couple of breadboards with receivers to various places in hallways nearby. Then I went back to the room and used the controller and went back to the breadboards to see if they received the signals. I was a bit concerned that someone might be worried by these electronic devices left in the hallways, so I put notes on them explaining what they were and with my cell phone number and email. This would be a good idea for any sort of weird looking electronics that you leave unattended.

    Then again, given that this is Google, I doubt anyone even batted an eye at a breadboard full of electronics with blinking LEDs lying in the hallway. :)

No public wish lists :(
