  • From the datasheet:

    Advice for the power supply * In order to stabilize power supply line, we recommend to insert a by-pass capacitor of 10μF or more between Vcc and GND near this product.

    ProTip: Do it! I tried throwing this guy on the same Vcc as an ATmega8 and the ATmega8 became completely unstable. After adding a 100μF between Vcc and gnd things were much better. My Vcc is still much less stable than without this part in there but it works…

  • Has anyone tried removing the IR filter on this thing?

  • Wow… It’s been fun to watch the SFE web site go from “takes some effort to load the home page on a normal day” a few years ago to “bring it, EC2” now…
    I truly appreciate the effort you guys put into ensuring that buying electronics stuff is fun, not to mention all the amazing tutorials and helpful resources for those not-so-seasoned veterans in the crowd. SFE for life!

  • Anyone know where that forum thread is? The link is dead.

  • Is anyone else’s mouth watering? That is one of the sexiest devices I’ve seen a quite a while.

  • I didn’t get anything but I still thought it was awesome. Way to go SFE! 4/10 top google searches for the day!

  • I just got this thing a few days ago and so far I’m loving it. There are a few things I’m still kind of unclear on, so I wanted to see if anyone else has any ideas.
    If I want to do IO (other than built-in buttons, light, and lcd) do I have to solder into the buttons or hijack one of the freq or ibutton inputs?
    Similarly for interrupts, it looks like the ibutton goes to an interrupt pin, do you just hijack that and use it as an interrupt?
    I’m working on a project where I’d like to be able to read a pwm signal from a maxbotix sonar rangefinder and output a pwm signal to a motor. It seems like I’ll have to do some hijacking though… (too bad there weren’t more pins broken out for general use).
    Anyways, any ideas/suggestions are greatly appreciated.
