I'm on a similar adventure right now, an ex-software person building a motorized iPhone stand that is Bluetooth controlled. It's been fun to see how with Fusion 360, a 3D printer, and JCLPCB you can build all kinds of devices. YouTube and GPT-4 are excellent tutors for hobbyists entering the hardware space. The 2 week wait for custom parts from China makes you realize the advantage they have over there when it comes…
What is the cost of your project? Could you share more information? I was looking to do something similar.
There's definitely some bootstrapping costs to acquiring tools (3d printer, soldering set up, adjustable power supply, Fusion 360 license). That's around $1k-1500 for a nice hobbyist setup by the time you get everything.
The real cost is when you decide to quit your software job to work on a hardware project :)
