/diy/ - Do It Yourself

for quick and dirty proofs of concept I use le ebin solderless breadboard and my minimal stock of through-hole components
for somewhat pernanent stuff that I'm in a hurry to build, usually it's a combination of cut copper tape and gouged board, which is good down to SOT-23 sizes. Pic related, a balanced antenna amp and bias tee, "free" Manhattan islands in lower right. sometimes I will use a .100" protoboard and my dwindling stock of THT components
for permanent and/or complex projects where I'm willing to wait a minute, I order prototype pcbs from china

>plain copper boards and they aren't cheap either.
if you order direct from chink they're like 5-20 cents each
plain single-sided boards are like a dollar each. use nibblers or (alternatively) tin snips to make islands. or, if you can find insulated copper tape, try that, maybe with a bit of Kapton tape for extra layering and jumpers
also, pro tip: SOT-23 can fit onto an L-shaped section of a .100" protoboard

probably not, if they paid the import tax too
