SMD Soldering at home
Most hobbyists are working on small kits layouts .And prefer the through hole parts.After the projects id done the board looks bulky and needs more space to fit. Never possible to make card size boards... build needs lott of wiring and connecting wires . I suggest why not explore SMD.Yes sourcing components is an issue ,you can use sites like mouser.com for parts .. before getting into details lets learn Smd soldering at home. Here are some videos you can refer: open youtube go through related videos ! Tools needed , just tweezers , and a fine tip soldering iron,and a liquid flux. For pcb try iron on pcb fabrication.
