We are living in great times for DIY, although ironically some of that is because of all the steps that we don’t have to do ourselves. PCBs can be ordered out easily and inexpensively, and the mechanical parts of our projects can be ordered conveniently online, fabricated in quantity one for not much more than a song, or 3D printed at home when plastic will do. Is this really DIY if everything is being farmed out? Yes, no, and maybe.
It all depends on where you think the real value of DIY lies. Is it in the idea, the concept, the design? Or in its realization, the manufacturing? I would claim that most of the value actually lies in the former, as much as I personally enjoy the many processes of physically constructing the individual parts of many projects.
For instance, I designed and built a hot-wire CNC foam cutter recently. Or better, I designed a series of improved versions, because I never get anything right on the first try. All along the way, I 3D printed new and improved versions of the plastic parts, ironing as many of the little glitches out as I had patience for. This took probably a good handful of weekends’ time, spread out over a couple months, but in comparison to time spent testing, fixing, and redesigning, very little time or effort was spent in the physical building.
Moreover, I bought most of the parts at the hardware store. The motor controller shield and cheap Arduino clone came from eBay. And even those that I did manufacture myself, the 3D-printed bits, were kind of made by a machine — my experience of the whole process wouldn’t have been any differen ..
