  • Nice price point. I’m saturated on the arduino side of the house, but it’s good to see you guys constantly innovating. Question: when you set the board to 3.3V, I’m curious if that has effect on the 328 since you’ll be running 16MHz at 3.3V. Any Xperimentation behind that added hackability feature? Also, why not just throw a DC-DC regulator with dual outputs on this bad boy and give the user some real power? Is the price point holding you back? Also, why not break out A6 and A7 if you’re going for versatility (you could use one with a v-divider to read the input voltage on the DC barrel jack or something clever)? If this rolls out of X, but some sexy silk art on the bottom, like a giant flame (unless that makes the boards more expensive). Adafruit products would suggest that you should step the style game up just a tad. I’ve got a lot of ideas. - Tyler

  • Since there’s no reset pin on the quiic, I’m having trouble using the libraries in the particle environment. For the cube example, the cube showed up, but never moved. The other example doesn’t work at all. Do you have any pointers?

  • SFE,

    For these motors, can we PLEASE get some sort of datasheet for each model, or at least a power and torque curve. That kind of information is important! These parts are too expensive to employ the guess and check method when you’re designing for complex systems!

  • I think aeroguy was mistaken. I’m pretty sure this chip acts as a power source. Putting them in parallel wont do anything to the voltage, but it should give you double the power. If each could output 150mA at 5V if Vin is 3V (let’s pretend), then two of them in parallel could provide 300mA total. If current doubles, power doubles (assuming constant voltage).

  • I would like to attempt to modify the Army standard issue watch cap. With winter coming up, being stationed at the National Training Center means 14 day rotations in the training area with no heat, A/C power, or other creature comforts. What’s worse is that while a Soldier is trying to relax in his HMMWV or Tracked vehicle, it’s not always acceptable to jam out to some tunes to pass the long days sitting in assembly areas and on observation posts. I want to try to use this; in conjunction with a LiPo battery, small speakers, and a few buttons; to embed an Mp3 player inside of the standard issue watch cap. I’d like to see how it stands up to the brutal conditions of ‘the Box.’

  • “Hey guys, I have this crazy idea: let’s take the light bulbs and make the conference room even brighter!”

  • “Bad news, we ordered the wrong light bulbs again. The good news, now we can start decorating for Christmas early!.”

  • How many EEs does it take to screw in 30 light bulbs?

  • “And to think… we almost hired someone to do the lighting! Think of all the money we saved!”

  • Hey, I have successfully used the larger verson to interface with an iPod, but this smaller one does not break out pin 11, the Serial GND. In that case, is the Serial ground connected internally to GND somewhere via some other pin? It makes sense, as the board breaks out Serial lines, indicating the use of Serial comms.

    Basically, has anyone used this to succesfully communicate via Serial?

No public wish lists :(
