    Does “Also good for an un-regulated, non-limited 5V supply up to 100mA” mean that you can plug a wall wart power plug with mini-usb connector into it to power a project (with appropriate regulation/filtering)?

    I got the 315mHz transmitter/receiver pairs to work without difficulty, running from and to PICAXE 08M and 14M microprocessors. I used 23.8cm straight wire antennas on each. I’m glad the 315mHz version is available–I tried 433mHz and found that I am totally swamped in that frequency. Apparently 433mHz is in or very close to a legal ham range in the U.S. which can transmit at hundreds of times the power.
    The description is somewhat misleading when it says, “Only one 315MHz transmitter will work within the same location.” Only one can work at the same instant, but for datalogging, with message transmissions of a small fraction of a second, many can work in the same space provided that you understand and work around the possiblility that collisions may occur with resulting data loss–so transmit multiple times with varying gaps between transmissions.

No public wish lists :(
