Sometimes you might need simple device that would log couple analog or digital channels. We all know that Arduino can do all of this and even more. But in order to save time something out of box would be better. Iviny though of this and build compact data acquisition device which is capable of logging or driving 2 digital and 2 analog channels.
This is Attiny85 based small Arduino DAQ with V-USB based communication. It simply logs data to computer or drives pins. Project comes with python script which allows plotting data and controlling pins with few mouse clicks. Currently logging speed is up to 150samples per second, but it seems that future firmware versions should increase this limit. Original design comes in custom 3D printed case and looks really attractive.
