Description This is an adaptation of the PSU that uses a 7805 and can supply higher current. You need to use an appropriate heatsink for the 2N3055 transistor, you could…
-
Description You can, with a little modification use a 7805 regulator to generate a variable voltage output, in the example below the output can be 5v to 30v. At higher…
