Here’s a JDM programmer for PIC microprocessors that works for me.


docs
I used it to put the bootloader on a usbpicprog PIC programmer I am building. It also programmed my PIC18F46K20. It worked with picpgm and picprog on Linux. Picprog still gave me config bit errors.
I have tried other JDM programmers–simpler ones using no transistors like Simple JDM programmer (though with not-quite-right zeners). It worked intermittently for a while, then stopped working altogether on my PIC18F46K20.
Here’s a JDM programmer that usbpicprog recommends. I haven’t tried it.

Note to self: on my HP LaserJet6L, board traces printed from Eagle using the PS device need to be printed out at 110%.

At Windycon, I went to a talk by Christian Ready from the Space Telescope Science Institute on the solar system and saw pictures of the surface of Titan. Wow, I didn’t realize that a probe had made a landing!

Dreaming Metal by Melissa Scott (1997).
No word cloud for this book, it isn’t on the net.
This book is a sequel to Dreamships (1992). I haven’t read Dreamships and as this book is clearly a sequel that left some gaps in this book. I didn’t know it was a sequel when I started it, but it is very clear.
That said, I enjoyed Dreaming Metal immensely. It’s one of the best written and most original books I’ve read in quite a while. The setting, an human settled world, is very interesting–complex, and yet very foreign and intriguingly different from the societies in most sf.
There is a lot that is not explained–Scott doesn’t give one of those top down explanations of the society, and the plot runs at the mid level of the society. I don’t know how much of this is covered in the first book of the series, I hope it handles it similarly. And interestingly, it’s not clear what the political system is. The characters are free to act within the plot, but there appear to be limits, different from the US, but not clear because the story isn’t about that, and the characters don’t butt up against them.
This book is about AI and music. It posits a world where AI is rare but crops up now and then, and it is considered inevitable but not predictable. It is very well written and Celinde Fortune is a great character. As described, the future of music sounds great. Also, deafness is common on Persephone, and signing and other physical performance is a integral part of the music.
Melissa Scott only wrote these two books in this universe.
