Eagle library for USB connectors printed directly on PCB.
USBQ is a Python-based programming framework for monitoring and modifying USB communications. Uses the kernel module from USBiquitous to implement the MITM part in the USB stack. Really does need an external device to actually sit in between the device and the system to sniff the data. Hmm.
This is the PSU board for all your retro modding needs like making a GameBoy Zero with any of the Raspberry Pi products and it’s Clones like Orange Pi, Banana Pi etc, it has even powered Robots. This board has all the features the modding community wants and needs for their build into a small and powerful package. Outputs up to 6A @ 5.20v. i2c enabled, so the power cells can be monitored.
This module implements a serial-level interface to the inexpensive USB-enabled geiger counters (available on Amazon) manufactured (or probably OEM'd, based upon how their docs read) by GMC. Does most of the fiddly stuff automagickally so you spend more time pulling data out of your sensor than you do figuring out how to pull data out.
Human Interface Device emulator for NFC readers. Reads the chip, outputs the contents as if it were a keyboard. Designed to run as a service in the background (or more accurately, a user daemon - since it requires the current user desktop session to function). The ideal time to start the program is on login. To avoid conflicts, the application will only attempt to load once. You may have problems getting it to work after switching users unless the first user logs out completely.
Requires pcscd, Python v2.7.
A boot floppy image that can be used for booting weird or recalcitrant machines from other devices, such as CD-ROMs.
Or, "You have LVM running on one box and an external drive, also running LVM, with the same volume group name - how in the hell do I mount the external drive?!"
