Really nice and detailed post about this DIY ultrasonic parking sensor. Nice work! Via ch00ftech Industries.
No, it’s not mine. One can dream…
Background and motivation
It should come as no surprise that I really really want a Tesla. Or really any Electric Vehicle for that matter. The only problem at the moment is that my daily commute takes me 20 minutes on foot each way, so I really can’t justify buying a car that will spend most of its life parked in a garage or parked in Seattle traffic.
That’s why I have to live vicariously through other people, and why I got super excited when I learned that my dad put down a deposit on a new Model S.
It hides it well, but the Model S is a massive car with a length of 196 inches and a weight over 4700 pounds. My dad originally planned on parking the car in his driveway, but when it came time to install the charging port, he opted for the garage instead. The only problem was that his garage only offers about six inches of clearance to be shared between the front and back of the car.
This predicament gave me some great gift ideas. With the holidays fast approaching and all of the other projects that I wanted to finish before heading home, I originally did a quick Amazon search for ultrasonic parking sensors. Sadly, most of them “bottom out” at a fairly reasonable one foot. I couldn’t find any that would drop to the two to three inch range.
So I added another project to my list and got to work!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
