  • I would guess that it has a rather substantial potential to trigger explosives when falling into the hands of rough foreigners who lack the naturally peaceful disposition of Americans.

  • Can the coin cell be removed from the holder? If not, one would have to integrate a charging facility in one’s design, and that’s presumably close to impossible to do with through hole components, so to use this successfully in a design, it would take considerably more than “rookie” soldering and prototyping skills.

  • Haven’t tried this yet, but the procedure seems to be: http://www.instructables.com/id/How-to-Solder-EL-Electroluminescent-Wire/

  • What’s a safe limit for the voltage? e.g. would powering this with 4 AA batteries still be safe?

  • Is it really safe to charge multiple devices at once through the Cerberus cable? Seems to me that if each of them is drawing 500mA, you end up drawing up to 1.5A, which is more than the port may be able to handle.

  • Works great! For the next iteration, though, you may want to consider a power switch — removing the battery every time you want to revise something is somewhat inconvenient.

  • Bad connections are definitely the prime suspect. All the “SCI” values, and especially the “VS Version” should be readable and correct, regardless of whether your card is correctly formatted or not.

  • You’re quite right, and I did not mean to imply that those pins would be entirely lost as digital pins. What I meant was that for each extra analog pin you use, you lose one digital pin, so in total you don’t get more pins, just more versatility for the existing ones.

  • Unfortunately, the extra ADC inputs are located on existing digital pins, so those are going to be even more scarce than they already were.

  • I’ve polished up some sample code to demonstrate the various techniques to play real time MIDI with this shield. By default, this is configured in “MIDI shield compatibility mode”, with the data sent through software serial and MIDI mode enabled with pin 4, but the code also demonstrates a more exotic technique for enabling MIDI mode, as well as the use of SPI for MIDI data.

    Real Time MIDI Code

    SparkFun would be very welcome to use this as an official code sample, by the way.

No public wish lists :(
