  • "PrintrBoard"

    There. I needed to leave the keyword because there is a gap in the documentation on how to get the Marlin firmware compiled before uploading it to the PrintrBoard with dfu-programmer. However, follow the documentation and install the module for the AT90USB1286 Arduino from PJRC.com and then compile and verify. If you don't know where your .hex file ends up, look for "~/.arduino/preferences.txt" and add a "build.path={add-relative-path-here}".

    Now I'm curious if I could make a Printrboard by using this Teensy.

  • Interesting idea, but two things:

    1: The resolution will make the projector have an extremely low pixel density. If you have a small, color cell phone from the early 2000s, look at it through a magnifying glass, and you'll see what I mean. 2: It's an OLED display, which does active emissive as opposed to filtered transmissive of the LCD. The only way you'll be able to make a projector out of this screen is by putting a magnifying glass in front of it and projecting an up-side down image on a wall. For examples, look up "Box Projector" on Youtube.

  • What about the need for one-to-many connections, since Wixel is only one-to-one pairing? Doesn't a Zigbee module allow more than one to connect to it?

  • In terms of those SMT resistors... is there a size code available, or are the pads large enough and the gap small enough to accommodate most 1/8-1/4W packages?

  • Oops... sorry. I figured it out. The permissions on the serial port required "dialout" group, which I removed myself from. I thought that being allowed to "Connect to the Internet using a modem" was a quaint, but silly permission. Little did I know that would stop me from talking to all serial devices...

  • This FTDI module seems to run great in Ubuntu 11.04 (using 'cat' and 'echo' with tx/rx bridged) but when I run minicom, the module stops working until my computer is rebooted. So the lesson for now is to not use minicom to test the loopback. Anyone else encounter this problem?

No public wish lists :(
