Re: Dog Treat Dispenser

Printing all the parts is less than 1 kg so if a roll of filament is say, 29.00 Canadian, that's pretty inexpensive. Your right.

This is all being powered off one usb power supply. Works great, no issues with the relays or anyth...

Re: wireless keyboard and mouse

The genius 8000 as indicated in my signature (and the list of approved wireless keyboards and mice) is a low power usb dongle that works great.
I can use it with a tenda311 WiFi dongle without having to use a powered usb hub.

@waltermixxx when i tried your power to usb cable my screen will only flicker for a millisecond, turn off, and repeat every few seconds. i think it may be due to the 5v to 12v regulator, considering power is coming through, or is it maybe bad soldering?

Sparkfun I2C level converter

https://www.sparkfun.com/products/10403 Can this be used with the raspberry pi without modification? Does the pi already have the pull up resisters in place? This board also does. Would they need to be removed? If I purchased the chip this is based on, would I need those pull ups on the 3.3v pi side?
