    This looks like a Teensy 3.1 microcontroller with a 74HCT245 used as a DC-DC converter. This is very similar to where I got to when trying to use a Teensy to run 130 LEDs, except this probably works better than my hack. The AAT3110 is a ChargePump that can give you 100mA of regulated 5V from a 2.7 to 5V input. It’s used to supply the 74HCT245 which give you a nice clean translation from the 3.3V output of the microcontroller to the 5.0V that the LEDs want to see. This should make it a lot easier to use the WS2812 LEDs, which can be very finicky, especially when you’re running a lot of them at the same time. I’ll have to try it out.

    Has anyone tried to interface this with the 32x16 LED Panel, https://www.sparkfun.com/products/12583 ? There is code written to interface it with the Arduino, but much of the library code is low-level and incompatible with the Teensy. I’d like to use the Teensy, because it provides enough power and memory that I need for doing animations and possibly other functions while running the display.

    I agree, there doesn’t way to be an easy way to use the claw and the bracket together. I would appreciate a tutorial or hookup guide.

    Robert’s “Light of Brilliance” project didn’t quite work as expected. Designed to light the bulb over whoever had the best idea, all the lights remained mysteriously dark.

    I’m using it to teach robotics programming to the 10 year-old twins, daughters of a friend of mine.

    For anyone dealing with the problem in the mean time, you can mount the top piece of the bot with just three of the hex spacers, and then use the remaining three for the line sensors, to get them a lot closer to the ground.

    I would also like to suggest that you include longer spacers for the line following sensors. On my bot, they are too far from the ground, so the difference between dark and light is less than the individual variation in the sensors. When the sensors are much closer to the floor, they seem to work fine.

    I figured out that the VI Package Manager was created by JKI. I contacted them at support.jki.net and they pointed me to an updated version of the package manager which works fine. I would post that link, but I’m sure it changes. If you’re having similar problems, try contacting support at JKI. They were VERY quick to help me.

  • Product DEV-11225 | about 6 months ago

    I now seem to be able to download packages using the VIPM I got from JKI. I’m downloading the Arduino interface now.

    I contacted JKI, the company that made the VI Package Manager, and they directed me to a new version they say fixes the bug. You can reach them at support.jki.net, if you are having similar problems.

No public wish lists :(
