I think aeroguy was mistaken. I’m pretty sure this chip acts as a power source. Putting them in parallel wont do anything to the voltage, but it should give you double the power. If each could output 150mA at 5V if Vin is 3V (let’s pretend), then two of them in parallel could provide 300mA total. If current doubles, power doubles (assuming constant voltage).

I would like to attempt to modify the Army standard issue watch cap. With winter coming up, being stationed at the National Training Center means 14 day rotations in the training area with no heat, A/C power, or other creature comforts. What’s worse is that while a Soldier is trying to relax in his HMMWV or Tracked vehicle, it’s not always acceptable to jam out to some tunes to pass the long days sitting in assembly areas and on observation posts. I want to try to use this; in conjunction with a LiPo battery, small speakers, and a few buttons; to embed an Mp3 player inside of the standard issue watch cap. I’d like to see how it stands up to the brutal conditions of ‘the Box.’

“Hey guys, I have this crazy idea: let’s take the light bulbs and make the conference room even brighter!”
“Bad news, we ordered the wrong light bulbs again. The good news, now we can start decorating for Christmas early!.”
How many EEs does it take to screw in 30 light bulbs?
“And to think… we almost hired someone to do the lighting! Think of all the money we saved!”

Hey, I have successfully used the larger verson to interface with an iPod, but this smaller one does not break out pin 11, the Serial GND. In that case, is the Serial ground connected internally to GND somewhere via some other pin? It makes sense, as the board breaks out Serial lines, indicating the use of Serial comms.
Basically, has anyone used this to succesfully communicate via Serial?

Turns out a portable garbage disposal wasn’t such a hot idea.
No public wish lists :(
