  • This is bundled with the Sparkfun Raspberry Pi 3 Starter kit: https://www.sparkfun.com/products/13826

    But at the official FAQ for the Raspberry Pi 3, they say it should have a 2.5 A power supply, while this is only 2.4 A. https://www.raspberrypi.org/help/faqs/#powerReqs

    So far it has worked fine for me, even with a camera module plugged in, but I guess it depends on what you're doing. So beware.

  • Before the built-in wifi on my pi 3 would work, I had to run this command from the terminal, to get it out of power_save mode, I guess:

    iw dev wlan0 set power_save off
    
  • WARNING: before connecting your pi to a network, be sure to change the default password! You don't want strangers, now or later, to notice a device named "raspberrypi" on the network, and correctly guess that you haven't changed the default password. Yes - people really do this. Change your password now.

    Use the "passwd" command, as documented at https://www.raspberrypi.org/documentation/linux/usage/users.md

  • When connecting via ssh, it is a hassle to have to figure out the IP address of the pi and type that in on your host. Thankfully, many or most host machines, on many networks, can use the multicast domain name service (implemented as Bonjour on Mac, Avahi on Linux, or typically third-party software on Windows) to find the address for the pi. Its name by default would be "raspberrypi.local". E.g. I just had to say "ssh pi@raspberrypi.local" from my command line prompt on Ubuntu Linux.

  • When I want to dance with my partner to our own personal music, for waltz, swing, lindy, west coast, salsa, tango etc, it would be GREAT to be able to wear this with some speakers positioned up high near our ears. I wouldn't expect much volume - just enough for two to hear and e.g. practice some steps before the main dance starts, or take advantage of a romantic opportunity when it arises.

    Adding some LEDs to pulse with the beat would be fun and could help a lot also if they were really in sync. It might be too hard for software to do sharp, reliable beats for dancing with some music genres, given the horsepower available, so it might require pre-processing and code that would play music and LEDs in sync somehow, even when stopped, rewound, etc.

No public wish lists :(
