  • How much power does this draw when paired with a Pi? What is the Vin requirements? It looks like it requires a GPIO cable from the Pi, what is this used for? The instruction sheet doesn’t seem too clear. For my project I need to have access to the Pi’s UART port and it would be nice to have a few more IO pins.

  • This is a great little board. It runs fldigi and gnuradio well and is simple to setup with the 7" touchscreen and Raspian Linux. 2 things to note, bluetooth setup may be a bit convoluted, and so far I have found it impossible to get the wireless to connect to a hidden network. It works well connecting to wireless networks that broadcast their ssid. I had found instructions on how to connect to a hidden network but they didn’t work and I didn’t have time to troubleshoot further. I am very surprised at the computing power of such inexpensive little board. Do yourself a favor: Be sure you have a power source capable of 5V and maybe 2A. My 1.5A cell phone charger is barely enough to boot it up. I have found that I sometimes need to have all USB peripherals unplugged, and plug them in one at a time after bootup. Also, buy a stylus. Your finger tips are probably much too big to operate most software programs running on a 7" screen ;). With the bluetooth setup you may find that blueman does’t work, in which case you may have better luck with a command line tool. I ended up having to uninstall blueman as it was interfering with the command line utility.

  • What is the flooring? Is it anti-static by any chance?

  • Why did it have to be named edison… Wouldn’t the “Intel Tesla” have been a far better name? ;)

  • I don’t know if this will help anyone but… One of the things I noticed about this sensor is when I connect it to a PIC32 UART port, if I try to program the pic or pause it when it is running in debug mode the sensor quits sending data. Often it will not start back up until it is power cycled. To solve this I put a 100K resistor from the white wire to Vcc. When the PIC is reset the pins go from being driven to being in a high impedance state, making the color sensor see a start bit.

    Hope this is helpful.

  • Translucent case with RGB LEDs inside that are connected to PWM channels so the user can select his or her own color. Password protect the color setting so when someone else borrows your meter you will see it in use from across the shop floor.

  • And over here, our animatronic technician will demonstrate the proper technique to replace a capacitor that failed our flame test.
