+## Futures ##
+
+If we decide to do further work on this design, a number of changes seem
+potentially appropriate for the next board revision, in addition to just
+fixing bugs found in the turn-on of the initial boards.
+
+* The LiPo battery support from [TeleMetrum](../TeleMetrum) should be copied
+ into this design, replacing the battery screw terminals with a standard LiPo
+ 2-pin battery connector.
+
+* The [SparkFun](http://www.sparkfun.com) folks have produced
+ a [USB bootloader for the LPC2148]
+ (http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=94). It
+ requires an SD card for temporary storage of code to be
+ flashed. Replacing the current external SPI memory chip with a microSD
+ socket could make sense. The socket size is under a cm square, and ones
+ that have a fold-up locking top are about $2, vs over $6 for the current
+ memory chip. The cards themselves are getting very cheap, too, and can
+ store much more data than the current 128k memory chip. This would require
+ moving ADC_Vbat to a different ADC input so that pins 27, 29, 30, and 31
+ would be available for the microSD socket.
+
+* Consideration should be given to changing the accelerometer for a higher-G
+ single axis unit as in [TeleMetrum](../TeleMetrum) if we want to be able to
+ use it for motor characterization.
