alt Hacker NewsBefore you dive too deep, check what's already available and let your tinker TODAY without having to solder anything. You can still do so, even design PCB and get them mailed to you (like I did, it's fun) but honestly spend a bit of time (and money) on CrowdSupply to see the plethora of fun and useful OSHW out there. IMHO only after having considered what's beyond the usual consumer electronics it is worth learning to build, not before.
Is there any prototyping software you'd recommend that could do this? I'd like to play with this stuff virtually without having to spend meatspace time/money.
