2022 Holiday Build Project Special!!
Added 2022-12-21 23:56:40 +0000 UTCMy yearly tradition of building an electronic gizmo returns with a very practical and fun project - building a regulated supply for my vintage Casio SK-1. Enjoy!

It's how it was done before Perf-boards became a thing.

2022-12-26 09:44:32 +0000 UTCIt may not be pretty but the important thing is it does what it is meant to. One thing I do is put a few 1N4001s in series of the input so the regulator does not have to work so hard. I did that in my 1980s 8 bit Sinclair so as not to stress the 7805. PSU said 9v it was banging out 12 volts under load. ZX Spectrum ran cooler as a result.

Now they have equivalents for surface mount generic boards. I use the same, or very close to, the PC board you use. I love point-to-point wiring on those boards and you can plan in your head where you want the components. Wonderful to see I'm not the only one out there still using leaded parts on generic PC boards. I think you would be the only one at a "Tupperware Party" asking questions about conductance, melting temps and suitability for housing electronic projects. :-)

2022-12-22 23:56:24 +0000 UTCYour construction technique is very similar to mine. I learned electronics in a vacuum (not literally) so I was never too sure whether my technique was legit or complete garbage. If anyone calls me out on it I'll just point to this video and say, "If it's good enough for a senior member of the IEEE it's good enough for me!"
