Re: Assigning same USBtty linux to a device every time

this is great. ive got one of those x10 "firecracker" modules, through a usb->db9 rs232 adaptors, and i added a rc.local rule to create the "firecracker" dev symlink to the usb device, but sometimes other peripherals grabbed ttyUSB0 first, and it drove me crazy trying to figure out why my system ran...

Re: Turning a motor on/off with a transistor

if you want to get a base of background electronics, like the operation of transistors, gates, and such, i highly recommend Forrest Mims books, "Getting Started In Electronics" is simply amazing, its like the best selling electronics book ever or something, he has more books that are all equally awe...

Re: Interfacing Raspberry Pi with RTC1307 without level shif

the ds1307 is a great chip. its cool hangin out with 3v3 or 5v, is not too picky about pull-ups, and will blink an LED! it likes a battery but can chill without one present.

caution is good, but the ds1307 is a champ, you guys are worrying too much. did i mention you can get them as free samples?

Re: Combined Usb Wifi/Bluetooth Dongle

i believe the reason to plug directly in vs. through hub is simply for power. usb ports generally provide 500mA, when an unpowered hub is connected, some devices are not able to get enough power. radio transceivers tend to fall in that category. so using a powered hub will overcome this. bonus, alth...
