Parking Spot Saver

On the left is an early prototype of a device I was developing in 2013 and on the right is the finished model. I have no training in engineering but took the project from concept to a production ready model (cheaply producible with a 40% profit margin) in under a year and having spent only a few thousand dollars on development. For years I would still get orders from customers but I'd have to apologise and send a refund because I hadn't gotten around to disabling the shopping cart on the website.
