Take a look on eBay for some of the older HP E series power supplies. They are really great supplies and you can snag them for pretty cheap. |

That's a rare deal, but it is possible to snag a good power supply cheap. |

If you still want a diy design, idk if these two are good (they look awesome though ;D) but i'm going to let more experienced people comment on that :-+ 1-2 amps versions: https://www.eevblog.com/forum/projects/diy-bench-power-supply-psl-24012/ 4 amps version: https://www.eevblog.com/forum/projects/diy-bench-power-supply-psl-3604/ |

Can anyone help me calculating how to get 12V out of XL7005A input voltage is 60V. I have calculated 30Kohm and 3Kohm resistors but I get 2V output! |

For 12V, you may choose 3.9K and 33K 1.25*(1+33/3.9)=11.82V |
