Several people have asked for it, so I spent my Christmas holiday playing with a board that downloads data from MicroPeak's internal eeprom storage.
Key facts:
* Logs barometric data every 192ms. Saves unfiltered barometric
pressure data in case you want to do your own pressure-to-altitude
conversions using actual atmospheric data.
* Logs 48 seconds of data. With only 512 bytes of storage, that's all
the space we've got. Should be sufficient to see the flight through
apogee for most airframes. Will still record actual apogee pressure
in case the ascent goes longer than 48 seconds.
* Download via USB. Uses a custom LED to USB interface board
(µPserial). New MicroPeak firmware flashes out the EEPROM contents
after showing the last flight max height. Takes only about a second
or so.
* Supports Linux, Mac OS X and Windows. Using the same basic software
framework that we use for our full-sized flight computers.
* $35 for the µPserial download board.
* $75 for a bundle including MicroPeak and µPserial
