I was looking for something like a smartwatch, that later on I could use to navigate and view exposed options and notification of the Pyra and invoke actions with. Actual smartwatches don't seem to cut it for me for many a reason - battery life, Android. Given the nature of the enumeration the latter serves as an collective term. Of the OSs, I know about, out there postmarketOS would be my favourite and the only interesting one to me, but they're not there, yet, and I'd be of no help to change that. I hate nothing more than trying to get something to work that's isn't either intuitive or somewhat usefully documented => I have no skill in that area. (I'm talking about the hardware, if you're unsure.) Then I was thinking something Arduino would be nice - given that I'm the kind of developer, who's utterly dependent on others to setup a project (make, git, etc.), something like "Put your initialization stuff here and your other stuff in the function, that get's called in an endless loop." would be perfect for me. That's almost all I know about developing for Arduino, btw, but it seems feasible. Now, for the life of me, I cannot find any wrist-worn housing for some Arduino stuff. I'd want something molded or CNCed or whatever - basically way more refined than something 3D-printed. Ideally, it would be a complete and preassembled kit or finished product and I'd just start coding, but if that's not an option, I'd be up to the task on: - buy soldering equipment and do the electrical assembly myself - if there's a nice housing not made to be wrist-worn but otherwise an adaquate choice, making and attaching something wristband-ish to it but not doing hardware work on the housing itself. Done by me it'd end up ugly and without the qualityies I look for and I wouldn't be happy with it. And I'd have no ambition to do it over and over, til it works out or something. Not for being lazy - lack of interest in creating things by hand. Or, if you will, I'm a perfectionist, but have the skill of a toddler, when it comes to those things - it's no fun. What I needed to go in there, would be some Arduino base module, of course, if not already there something for Bluetooth connectivety, a Display, an additional rgb led would be a bonus, some accoustic output thingy like a buzzer, a means of input like four buttons or a scrolly thingy and two buttons, a battery, and having an accessible usb port would be great. The housing being prepared to get it rain-proof would be important to me, too - again, I've got two left hands while being right-handed. Then the housing shouldn't be too thick - 2 cm would be pushing it , I guess. I wouldn't mind a multipart housing to be distributed around the wrist, though, as long as the thing brings the means to interconnect the parts rain-proof. So, that's what I'm searching for unsuccessfully. If anyone know's something, that'd met my demands, telling me about it would be very much appriciated. Thanks for listening.
