They make products of all different level of quality. --- End quote --- Unfortunately distinguishing the good produces from the bad is practically impossible, making them all bad. China has become the Nigerian Prince of counterfeit products, with companies like Ebay, Newegg (Chinese owned now), and Amazon helping. --- Quote from: AG6QR on May 04, 2023, 12:16:11 am ---If you want to build a power supply as a learning exercise, it could be a good project. But it's likely to end up costing more and being of lower quality than a commercial supply. It might be worth it if you end up learning enough from the exercise, though. --- End quote --- A variable bench power supply is an excellent learning project. It is too bad that there are not any good kits. I would also consider rebuilding an HP/Harrison power supply, or something similar that has full documentation. |

What's your soldering iron? It may be able to run from an old laptop power brick. The voltage will be lower (~19V), so heat-up will be slower. |

You think this is a bad power supply that would burn down your house? https://www.testequipmentdepot.com/bk-precision-1901b-programmable-switching-dc-power-supply-32v30a-120vac-line-input.html?ref=gbase&gclid=Cj0KCQjwr82iBhCuARIsAO0EAZyxBpiROwMSLyV_I-WSqU-l_lfiNhWB-rO3-JCeLmJYt3EL1qJgSlsaAmdIEALw_wcB And yes it's made in China. |

Everybody knows that when one speaks of "Chinese products" they are referring to the no-name domestic market junk that is prolific on ebay, aliexpress and so many others, not the high quality name brand stuff that is manufactured there. |
