Solder fumes, ahhh that brings back memories…
Today, I built a little ultrasonic sensor to help me park the car. Took the easy way out and just purchased a simple kit from Conrad:
Now, instead of driving the car up to the point where some cardboard boxes leaning against the wall move, and then backing up, I can drive until a red LED comes on, and then, ehm… back up ever so slightly until the LED goes off. Progress!
Well, at least it gets rid of the old cardboard junk I was using as “bumper”.
