  • If a cyclist can ride right through this, why can’t I on my 125 motorcycle?

    Perhaps it should be allowed! Cars already treat stop signs as yields (“California Roll” is the car corollary to the “Idaho Stop”). Why would you stop if the car behind you isn’t planning to? (I’d love to see motorbike studies on this; please link me to some if you know any.)

    Studies have shown that cyclists treating stop signs as yield signs leads to fewer accidents, both with cars and pedestrians.

    Yielding also decreases time spent in the intersection. You have a motor underneath you. Cyclists don’t. Clearing the intersection quickly prevents cross-traffic from splatting you. That’s why slowing down, checking for traffic, but not stopping is so important for momentum vehicles.

    The NHTSA (the US road safety org for my Canadian friends) has a good two-pager overview. It’s a good place to start if you’re still curious about the reasoning behind the Idaho stop.





  • You’re probably decoding noise or in the middle of the bit stream.

    What you’re looking for is called “preamble.” That’s a sequence of bits used to synchronize the decoder (marks the start of data, useful in modulation schemes for clock recovery, and a few other things).

    Looking at minimodem’s manual, try using the sync-byte option. Prepend your tar stream with a string of bytes, like 0x01, before sending to minimodem for encoding. Then use the sync code option to mark the start of the tar bit stream. This is as simple as cat preamble.bin myfiles.tar | minimodem --tx …

    Other things to consider: start small with 300 baud BFSK before speeding up. Test with wav files before attempting physical tape or speakers and a microphone.
