    Is there any reason why the RESET pin isn’t broken out? It seems like you should be able to trigger a read by toggling that pin. (eg: to see if the card that was read a second ago is still in range). Am I wrong about this? Please let me know before I start soldering on this board unnecessarily :)

    if you do a part 2 of this experiment, maybe you can add the wixel too.

    this thing works great. when i use 8 ohm headphones it’s fine, but if i try 32 ohm studio headphones (i’ve tried several different pairs) it freaks out. any idea what the easiest solution is?

    FYI I just finished building a project that uses this product in combination with the wixel arduino shield and 2 wixels. Pressing buttons in one location causes one standalone wixel to send the wixel that’s stuck to this relay box (via the shield) a message via RF. The receiving wixel sends a serial message to the relay box saying which relay to turn on/off. Works like a charm. I thought I’d have to do some wixel programming and some arduino, but it turns out it only needed wixel stuff. I’ll be posting info on the project, along with the wixel app soon. Just thought I’d let people know that it’s possible. Only issue is that the case doesn’t fit back on the relay box, since the wixel sticks up too high.

    after a day of working with them, i can confirm that they are indeed pretty damn awesome. not sure why, but they don’t seem to like the sparkfun TOL-10214 wall chargers. the yellow USB light on the wixel flashes constantly, which is supposed to indicate some USB communication happening. it seems to work other than that yellow LED anomoly, but i went for a wall wart directly to VIN and GND instead.

    no, you cannot. you can talk to it from an arduino with the wixel shield for arduino, though.

  • Product WRL-10665 | about 3 years ago

    i’m just starting to mess with these for a project that i’m working on and i have to say they seem pretty damn awesome. the bias is toward using apps that others have written (the examples that come with the sdk and appear on the site, for example) and it seems like creating your own apps definitely relies on modifying the examples. with that said, there is a lot of great stuff that can be done with this board. RF transceiver, 2 UARTs, configurable variables/parameters from outside of the app (using the Wixel config software), etc. don’t try to give the I/O pins 5V (they need 3.3V) and note the current limits on the pins - only 4ma for most of them, so I’d guess you have to use a transistor on those pins to drive even an LED.

    Am I crazy or is this part not really in the SFE Eagle Library? Thanks for any info.

No public wish lists :(
