DIY Electronics Enclosure
Electronics are cheap
Electronic modules are getting smaller and ever more powerful. For example, modern MCUs are packed with capabilities, and at a very low cost. In addition, making a custom PCB (via JLCPCB for example) is often more time/cost efficient than breadboarding. These are all good news for DIY electronics fans.
I still remember the old times when I had to save lunch money to buy a single transistor, and then went sad for days after unknowingly damaged it…
