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 protection. 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.
Pop over to Hackaday.io to start your entry today. Don’t forget to use the “Submit project to:” drop-down box on the left sidebar of your project page to make sure it’s considered in the contest. You must have your entry in by April 19th!
That looks like a fragile platform for that rain barrel!
When full how much weight will be pushing down on it?
Well if it’s a 55 gallon barrel, at 3.8 litres per gallon, and 2.2 pounds per litre… then about 2.1 x 10^5 grams
If you flick through the project gallery, in the pic with the tomatoes it looks more like it’s square section steel, so probably okay if it’s painted well enough to fend off the tinworm.
Show professionals.
That calculation seriously hurt my head.
If it’s a 207.9 litre barrel (55 American gallons), then 207.9 kilograms.
I’ve decided to be unit agnostic to give everyone a couple of degrees of freedom. That’s 2.033333 Sumerian degrees of arc, or 3.6 Fahrenheit.
Incorrect usage of oak barrel. There are much better things to put in them than rain water! Maybe if it’s had some barley/corn steeping in it for a while…
