I’ve long wanted to make a professional enclosure for SwitchMote and do away with the acrylic covers and all the screws and spacers. All these parts add a lot of overhead and cost to the kit.
SwitchMote was designed to be a DIY modular/hackable/educational kit (so far at least) that uses mostly “off the shelf” parts. In the past months I’ve invested into a SwitchMote enclosure design. The PSU side would be cool in clear plastic, below is a rendering:
The good news is this can be made very solid and simply snaps onto the top and bottom PCBs with some cleverly designed tabs, without the need to use any spacers or screws or other exotic mating methods. I like to simplify and KISS everything. The enclosure can also accomodate the recently released PIR option, below is a prototype:
The bad news is the eye watering cost to make the moldings for this. The cost of UL certified fire retardant material is also expensive. I would need to put SwitchMote in HomeDepot or go to Shark Tank for that to make financial sense. So at this point I’m looking at alternatives, one option is silicone molds that can produce a few hundred units at most.
Another option is to go the 3D printing route and make these right here in the shop. I’ve had a prototype built on an FDM printer and I’m quite happy with the quality and strength, the downside is detail. Because the front panel is the only exposed part, that could be covered in something else that is nice and smooth, and perhaps allow for any color the user wants.
There are many other ideas cooking as to make SwitchMote more feature rich, realiable and easy to use. For now an enclosure would be one step closer to professional looking (yet Arduino based) IoT switch (that doesn’t suck).
Ideas, suggestions, feedback and help are always welcome!
