Just wanted to report on completing a quick electronics prototyping project - making a very tiny ATTiny45-based simple USB dongle.

Just a bit of online research on a small footprint Bluetooth-enabled Arduino clone for prototyping:

I needed to create a small, cheap USB-enabled circuit to serve as a key logger, and I've found some nice projects online that explain how to do this.
I found out you could use an ATTiny85 to run the V-USB software USB stack, and I only needed the one input pin to gather data (it's going to be a USB "That was easy" button).
Since this was done so many times before, I will be brief, and try to point out problems I had instead of a regular tutorial.

Just putting it out there for whoever is trying to use the C329 camera module of the SPI variety (the URAT module has code posted online)

Just wanted to put up a small tut on how to put an Arduino bootloader on an ATmega88.
I very roughly followed:
http://itp.nyu.edu/physcomp/Tutorials/ArduinoBreadboard (Although they make it way too complicated)
And ATMEL's datasheet for ATmega88 is also very good to have open at all times:
First, put everything on a breadboard: (This took me a while... Thanks D.Mellis and M.Feldmeier!!)
(Fritzing is awesome)

Just a quicky on how I hacked together a DIY Microsoft Kinect port. The Kinect port is non standard, USB-like port, and to actually connect it to a PC you must buy an adapter from microsoft for >30$. This is whack. You should make your own. All you need is access to a lasercutter, vinylcutter, plexiglass 1/8", some copper sheet and solder equip.
