Back in college, I etched my own PCBs in tupperware with muratic acid, with Sharpie marker as the mask. Nowadays I buy $2 (for 5) PCBs from china. Equipment-wise, you can reflow SMDs quite well on a frying pan.
- JAlexoid 6y agoYeah.... I reused most of my $1.50 perfboards 2-10 times. Reusing expensive components, such as $4 MCUs and not frying them in a literal frying pan - is critical. A DIP socket literally made it possible for me to do MCU programming with my $5 soldering iron, that would normally fry an MCU. Nowadays I buy prefabed modules and uSBCs for $30 each and throw them out - not as my main job as well.. Yet I know really well what access to start in the engineering field means for people whose budgets are $80 per month on food and clothes.
