  • Product ROB-12090 | about 5 months ago

    Isn’t this a bit too expensive for a plastic box, some wheels and 4 motors with reduction boxes? I don’t really see anything that justifies the $45 price tag :/

  • Product COM-11151 | about 2 years ago

    There is a way around it: http://www.geofex.com/article_folders/bypass/bypass.htm

  • Product COM-11154 | about 2 years ago

    Yes. It would be a very nice addition.

  • Product LCD-00255 | about 2 years ago

    This is a very late response, but anybody in this situation can simply connect the LCD in series with a MOSFET. YOu can then switch the LCD on and off from a microcontroller. Remember to leave all the microcontroller outputs floating because power can still flow into the LCD if you keep these in certain states.

    It’s better to use PWM and a temperature sensor. PWM is better than a DAC because less heat is dissipated through the transistor that is going to control the blower. As for the temperature sensor, I recommend you to use a thermocouple and an appropriate chip to receive these values. I think there’s an Arduino example for that. (I even found a shield on a quick google search). Inside the chip you will basically compare the set temperature against the measured temperature and adjust the motor until the readings are the same. You have to do something to slow down the motor response, so that it doesn’t en up turning all the way on or off like a clothes iron.

    http://208.173.184.182/oem/Pdf/MX2400.pdf This is for a Duracell battery, but given the fierce competition, the specs should be similar. It’s under Nominal Internal Impedance and it tends to get worse as the battery gets discharged.

    Something like the Power Driver Shield will do the job easily. Having that computer power supply is almost overkill unless you want to use more solenoids and power more motors and mechanical actuators and stuff like that.

  • Tutorial - Nest Teardown | about 2 years ago

    The Zigbee radio is used to connect with other Nests in the house when WiFi is not available.

  • Product GPS-10582 | about 2 years ago

    I checked the design files out and they look quite nice. The schematic is well laid out. There seems to be quite a lot of space remaining in the PCB for more traces, so you can make the V5 based on this design. I really like this kind of designs with microcontrollers and lots of sensors and actuators.

    Thanks for clearing that out. I have 5+ designs (just one of them will actually be assembled) which use LiPos.
