Hello HN! This is a ridiculously long but thorough guide to building your own hardware on a budget. Turn Touch is a small wood remote that controls your smart home.
I built it because I wanted it to exist and I was tired of waiting for somebody else to build it. And because I believe so heavily in open source, I wrote up detailed instructions on how to build each phase of the process: the PCB, CAD, wood machining, and laser cutting.
Turn Touch is also on Kickstarter, which is the culmination of 3 years of learning and work. I'm a solo indie developer and if I can learn to build this, so can anybody else.
Thank you for this series of posts, it's full of practical advice on how to design things. I especially like how you've condensed what must be months of experimentation and experience in a few short paragraphs, with diagrams and everything.
As a long-time software guy learning more about hardware, I find these kind of deep dives immensely useful. Much of building a physical device seems like a black box, from choosing electronic components, assembling them on a board to do something useful, writing firmware, getting it fabricated, seeing it broken down step-by-step (even if this is only one particular example), it makes everything much more accessible. Keep it coming!
Yep, this is exactly what I wanted when I was starting out. I just had the resources and time to write everything done as I went through it in the hopes that other people take it and can make even better tools and open source docs.
I recently spent a bit of time playing with the idea of making an IoT doodad, so this is pretty cool to see.
I was wondering if you had any thoughts on how to mass produce this, but looking at the Kickstarter it looks like you've doubled your goal with only 500 backers, so maybe that's not a useful question to ask.
One of the things that was unexpected for me when I was investigating was that I would need to get some kind of certification done by UL or someone else; have you gone through that process/what was it like?
Also, did you find a PCBA house that would also flash your microcontrollers, or do you need to do that manually?
At 500 remotes, I'm planning to flash them myself. And I just called a bunch of factories to get quotes on box build assembly, wood machining, PCBA, and injection molding. It just took time to work on the manufacturing quotes.
While this is a good submission and likely earned many upvotes legitimately, that doesn't justify gaming the system, which is why I am highlighting it.
Although, normally I would agree. But it seems to me that the op is sharing a lot so you could create it for your selve. So, actually, I can't blame him.
I mean come on. I'm asking friends to vote for my post. I wrote an enormous post that offers a guide for many people looking to build their own hardware. The least I could do is get it as widely seen as possible.
