Bending notes with PT2399…
i’ve been experimenting with this PT2399 chip and using various schematics to create a digital delay circuit. the delay time seems to be directly attached to the sample rate since lengthening the delay time gives a nice decrease in pitch. i’m toying with the idea of dropping a time constant in around the controlling delay…

Photos from space…
APT (Automatic Picture Transmission) is a relatively older method of transmitting satellite photography. I’ve been attempting to catch a pass of the NOAA weather satellites for quite some time now, but feared that the radio interference of New York City would make it difficult without building some gear. My assumptions were correct… but not entirely.…

LightBox prototype
here’s a small battery-powered guitar amp that i’ve constructed from reused parts. the housing is a busted computer power supply (some of which is in the No. 5) as well. i’ve got several options for this little fellow in mind, but, for now, it’s a tiny amp with a mean distortion. lo-fi enthusiasts should contact…

No. 5 speaks.
and what a lovely voice it is. even through a Crate speaker (i’m saving the better speakers for when the testing phase is over). overall, i’d say a success for cheap transformers, Radio Shack parts, and a few pieces taken from a busted computer power supply. audio notes: it was late, and i was annoying…

No. 5 come alive!
like Dr. Frankenstein, it’s about time to bring this little fellow to life… or at least try. the schematic i have is a random luck of the draw internet find, and i have no idea whether or not it will work. however, testing will occur on the work bench soon enough to determine what needs…

Piping hot ball of Tar.
For those who have gotten into the idea of typing commands as little as possible, here’s out to pipe the output from tar straight into a gzip file. tar cvf – myfile.jpg | gzip > myfile.tar.gz tar cvf – folder | gzip > folder_backup.tar.gz Take note of the second example and notice how folder does…

I found the F (-mtime +3)!
forgetting is the bane of my existence. don’t ask why. i’ve forgotten this syntax enough times that i should have it tattooed on my upper arm. in fact, I think i’ve posted it on my own site before and forgotten about that. find /path/to/files* -mtime +5 -exec rm {} \; the first argument is, of…
