Intelligent Deterrence
The photo shows assorted boards, including the early, RFID-based authentication that the system was using. There are at least two different RFID boards in this.
A faint attempt at lazily, quickly getting an idea of how much of an effect a horn could have on loudness: It had an effect, but with the expected loss in quality. The loudness was far from enough, anyway.
A collection of some of the various speakers tried in the years-long pursuit to achieve loudness at the smallest possible size. Note that, initially, the goal was to design a system that could fit inside a bike frame! That had many ‘impossibles’ to overcome, the hardest of which was loudness. Even when the design changed […]
A June 2017 test. It seems to be a surface transducer being tested on a tin can–in this case, a Nellie’s laundry detergent’s–to check for improved loudness. IIRC all such tests failed to impress me. And they were indoors!
This was a test to see what riding away would appear like, to the system. The electronics were placed in a shoe box, atop a bike trailer. The laptop rests on some padding, IIRC, in order to make things a bit more difficult for the system. The bike then rode away.
This seems to be a SAMD20 board (which IIRC is the only 32-bit CPU I ever tried for this product), possibly with a bno055. I think it was an accelerometer/gyro/whatsit I was testing back then.
This was one of the early experiments with playing a human voice. The shot was taken on 8 April 2017. It was a Nuvoton board, I recall.
Over the past few years, I tried a number of different micro-controllers to design the system with. It started with an Arduino Uno, then went into different sizes and capabilities until it ended up in a different Atmel AVR. Now, with the project nearing completion, Covid has put a stop to completion of the design. […]
No CPU stock, so a different CPU must be found and ported-to.
As yet, the product is months away from any sort of release. But, I’m already thinking about the experience of the initial customers. It’d be best if the early buyers provide feedback about their experiences. This can be fed back into the design cycle, hopefully improving the product. To encourage this, companies typically find beta […]
