Little Wire SMD

I came across the Little Wire a few months back. I thought it was a pretty cool idea to have a few GPIO's accessible over USB. More than that, it also offers several serial protocols (I2C, SPI, etc), dual channel ADC, and even works as an AVR programmer, all in a neat little package! To make it even littler, I designed an SMD version of it.

I especially liked it for using a software implementation of the USB protocol on an attiny, which means I should be able to use an attiny in place of the much larger (and more expensive) FTDI chip.

(Mostly) Organized Resistors in 20ish Drawers

Organizing electronic components is important if you want to spend more time building prototypes than looking for the right resistor. The problem is, there's just way too many to organize without spending a ridiculous amount of money and space on a billion little drawers....
