A Cheap High-Current Bench Power Supply

If you've ever had to buy a high-current bench supply, you'll know they don't come cheap. But you may well have such a supply sitting unloved and (until now!) unwanted in the back of a cupboard. It's the power supply in that old computer you never quite got around to throwing away!
A Dirt-Cheap, High Current Power Supply
Here's yet another use for that pensioned-off AT computer that's gathering dust in the corner.
Col Hodgson
The concept of converting a disused computer power supply to 13.5V operation was first mooted in the November & December 1998 issues of the no-longer-published "Radio and Communications" magazine. This article builds on that information.

Isolation and structure assignment of an antimicrobial principle from the volatile oil of Nigella sativa L. seeds.
El-Fatatry HM
Pharmazie. Vol.30(2) 1975 109-111 PMID: 238225
Abstract
Refrigeration of the volatile oil of Nigella sativa L. seeds eventuates in a crystalline substance. The chemical structure of the compound was drawn from its chemical behaviour, as well as from its UV, IR, PMR and mass spectral data. The compound was found to be thymohydroquinone: confirmation of the structure was established via the preparation of its corresponding diacetate ester. The compound was found to have high antimicrobial effect against gram positive microorganisms.
Note by no1uno: I realise this would be available ONLY through PubMed, but I suspect it is kind of important if anyone in future wants thymoquinone (reportedly up to 30% of the easily available oil). Could be kind of useful.
