I am considering a simple, low cost logging dongle for use in harsh environments. It would have the following features-
uProc with RS-232, regulator and 1Mbyte SPI flash
USB and Serial connectors
Identify VEMS when attached and issue data dump requests - log resulting data stream
Accepts commands when connected to host (PC or PDA) to dump data
On board USB rechargable coin cell or host powered (5V on VEMS DB9 or USB on PC/PDA)
BoM, board, assembly and testing = cheap
Firmware = easy
Podded in epoxy for ruggedness
Anyone interested, please chime in. Cost for members should be kept in the $20 range.
