New Hackaday Contest: Earth Day Challenge

The Earth Day Challenge is now under way! Spin up your take on an Earth-Day-themed electronics project and you’ll be in the running for one of the three $200 shopping sprees at Digi-Key, who are sponsoring this contest.

This is all about raising awareness for environmental projection. You might considered something as direct as measuring and plotting air quality data, or as abstract as weighing your home’s recycling bin and garbage bin and making a game out of generating less waste in general, and boosting your recycling-to-landfill ratio. Find an application that can be moved from grid-power to solar power, or build a carbon-savings counter that calculates the impact you have when choosing your bike over a car. The coolest projects are the ones that make us all think in new ways.

In addition to those $200 prizes for the top three projects, there are $50 Tindie gift cards for the twelve most artistically presented projects. Digi-Key is looking for great images to include in a wall calendar for 2022.

Hot Camera Contest: Build A Battery Powered Thermal Camera

Here’s a challenge for all you hardware hackers out there. Peter Jansen has opened up the Hot Camera Contest on Hackaday.io to use a thermal imaging camera in a battery-powered project.

The challenge here is simple. Use a Flir Lepton thermal imaging camera module in a battery-powered configuration. There’s a catch, though: this is a project to use the Lepton in radiometric mode, where the camera spits out an actual temperature value for each pixel. Yes, this is a documented feature in the Flir Lepton module, but so far very few people are using it, and no one has done it with a small, battery-powered device.

The rules for this challenge are to use the Flir Lepton 2.5 in radiometric mode using either the Raspberry Pi Zero W or ESP32. Any software in this challenge must spit out absolute temperature values in a text format, and there must be a demonstration of putting the Flir Lepton into low-power mode. There are two challenges here, one for the Raspi and one for the ESP32; and winner will be named for each.
