Sunday 6 February 2022 The Supply Crisis caused numerous problems. The latest is a behavioural difference in a new piece of hardware that now needs to be catered to. Highly annoying at this late a stage! On the plus side, the enclosure is nearly ready. The metallic components have been prototyped, with some tests remaining. […]
Just a quick post, because I’ve not posted in a long while. As well as a port to a new micro-controller (something that many firms have to do nowadays, thanks to the Supply Crisis), a new version of the PCB, and a hell of a lot of work on 3D printing, there’ve been many different […]
As with any product nowadays, naming is a much more complex undertaking than it was in the past. Checks have to be carried out for the domain name (especially .com), existing products or variants, groups and individuals on social networks, apps, trade-marks, patents, jurisdictions etc etc etc. And, while you’re developing the product, other claimants […]
Just a quick update. I’ve spent a lot of time on trying to find a local metal-shop that could help with the manufacturing of the enclosure. The main body of the latter _I_ will do, but the end discs are more problematic. Unfortunately, and to the best of my knowledge, they are typically made through […]
As outlined in some of the history of the Minder1 theft-deterrent for bicycles, the original hope was to mount the system inside the bicycle frame. Chief among the consequent problems was the difficulty of achieving loudness. The latter is determinative in the current (autumn 2021) size and mounting-point of the system. But it is not […]
With prices for off-the-shelf enclosures having risen, and supplies dwindling, I’ve had to consider making my own. Yet again! I’d started off by naively thinking of local, custom production. And the obligatory 3D-printing. Then, I ended up researching metal fabrication–even welding! The current focus is on sheet metal. All the going-around-in-circles eventually bore fruit: Riveting […]
As already outlined, my only recourse for an affordable enclosure for the product has been an off-the-shelf metal can. Simply, custom manufacturing would result in a cost of hundreds of dollars per enclosure, unless if I order ten(s) thousand of it! The product’s enclosure has to meet some basic requirements. It has to: And whatever […]
A lot of time was spent, over the (2+?) years, to find a way of generating loudness via the bike frame. While this is very possible, it will not be a commercial product, installable by average consumers. And frame modifications are never a desirable option! 🙂
Back in June 2016, when this whole thing started, my idea was to place the system within a bike’s frame. This caused numerous problems, which I will outline in future posts, as time permits. Below is shown a photo of one of the August 2017 tests. Literally hanging by a thread is a speaker or […]
The loudness journey started with Class D amplifiers, due to their low power consumption. But, aside from loudness never quite being sufficient, I had various problems–noise, and perhaps occasional deaths, being chief among them. Eventually, I moved to power amplifiers. But, given the size constraints on the speakers, and the outdoor noise that was to […]
