Data Loggin' Contest!

This contest runs from Tuesday, March 2, 2021 at 09:00 am PST to Sunday, April 25, 2021 11:59 pm PDT, projects must be created or updated and submitted during this timeframe. Projects submitted before or after these dates will be disqualified.

Capture and log data on the world around us using your preferred sensors and hardware. Then plot and analyze the data to show unique insights. 

Bonus points: fork someone else's project here on (make sure to credit the original designer), and MAKE IT BETTER! The new project must be different and credit the original designer to qualify. 

For example, check out this Bitcoin Tracker, or this easy to build Raspberry Pi recorder. Check out the accessible battery-powered data logger design used for the Cave Pearl Project. Need more examples? Check out the Data Logger project list.

Individuals and teams of all levels of experience are encouraged to enter. A simple microcontroller data logger can be constructed for under $20 and can be assembled and working in less than two hours.


Three $100 Tindie gift certificates will be awarded; one in each of the following prize categories:


A couple of ideas to get the creative juices flowing:

There are several tutorials on how to build your own microcontroller-based data logger available online.
