Hi Jason, Thank you for the comments (and the order!). The first batch of boards was very small due to parts availability. Still waiting on a zener to come back in stock (current estimate is beginning of May).
The cape firmware does currently allow for a timeout to be set that will power the BB back on. The cape also monitors 3V3 so it knows when the BB has powered down and then will then cut 5V (and reset the timeout if you've set one). It is my intention to add a RTC to the firmware but I really need to create a kernel driver for it to provide the proper RTC interface and so that everything else is accessible through sysfs. I have thought about moving the components to the "bottom" of the board to make the top "slick". I'd probably have to scoot a component or two around but that should be completely doable. These lithium battery packs get pretty small. My final prototype now lives in a Logic Supply case which I think is a pretty nice setup. Without the stacking connectors, the cover just needs to be raised one position. Photo here<http://andicelabs.com/wp-content/uploads/2014/04/P3_BBB_LS.png> . The reason that I put the JST connector onto the cape is because the lithium packs from AdaFruit and SparkFun seem to all have them pre-installed. The battery in the pic is from AdaFruit and is 1200mAh. That runs an idling BBB for nearly 3 hours! -Ron On Monday, April 14, 2014 8:49:37 AM UTC-5, Jason Kridner wrote: > > On Fri, Apr 4, 2014 at 11:09 AM, Ron B. <[email protected] <javascript:>> > wrote: > > Hello fellow enthusiasts, > > > > Please check out my Power Cape and let me know what you think.
