A software only solution to the vexing beagle bone black PHY issue

Josh Levine has a nice write-up about a software only workaround for the Beagle Bone Black PHY issue:

Sometimes the Ethernet port on a Beagle Bone Black does not work on power up. It takes either a physical reset button press or a power cycle to fix it. This problem affects all BBB’s and until now could only be solved with hardware hacks.

The final official word from TI on this problem:
“There is no solution for this on the BB Black“

8-bit assembler compiler

Dilshan Jayakody writes, “8-bit Assembler compiler is NASM compatible assembler compiler to generate binaries for 8-bit x86 like CPUs. The binaries produced with this compiler can execute on Marco Schweighauser’s 8-bit virtual Javascript CPU.
This native compiler can build using Lazarus / FPC. During the implementation we build and test this compiler successfully on Linux and Windows operating systems.”

Pulling Music Out Of The Airwaves

RADIO WONDERLAND is a one-man band with many famous unintentional collaborators. [Joshua Fried]’s shows start off with him walking in carrying a boombox playing FM radio. He plugs it into his sound rig, tunes around a while, and collects some samples. Magic happens, he turns an ancient Buick steering wheel, and music emerges from the resampled radio cacophony.

It’s experimental music, which is secret art-scene-insider code for “you might not like it”, but we love the hacking. In addition to the above-mentioned steering wheel, he also plays a rack of shoes with drumsticks. If we had to guess, we’d say rotary encoders and piezos. All of this is just input for his computer programs which take care of the sampling, chopping, and slicing of live radio into dance music. It’s good enough that he’s opened for [They Might Be Giants].

Check out the videos (embedded below) for a taste of what a live show was like. There are definitely parts where the show is a little slow, but they make it seem cooler when a beat comes together out of found Huey Lewis. We especially like the “re-esser” routine that hones in on the hissier parts of speech to turn them into cymbals. And if you scan the crowd in the beginning, you can find a ten-years-younger [Limor Fried] and [Phil Torrone].
