[Jean] wrote in eager to share his latest project, a standalone temperature logger with USB connectivity. Back in November, [Jean] found himself wanting a temperature logger that was roughly the size of a USB memory stick. What he found on the market was not quite adequate in terms of price or size, so he decided to design his own. His would be the size he wanted and wouldn’t require any software or drivers to run. You simply plug it in, edit the configuration text file to set your intervals, and off you go!
You can follow along through the entire design and fabrication on his site. He’s really great about discussing why he made each decision and how he resolved any errors he ran into. You can download the schematics and source code on his site.
