Hi hero999,
here is my impression of that site:
I guess I'm not alone thinking a bench supply is one of the most important devices an electronic freak needs to work with.
My philosophy about impressions concerning acquaintances is the initial impression which more or less earmarks a person and is ones primary factor of like or dislike.
I like the idea of the Bipolar Power Supply, but I don't like it's presentation. There is a picture (could have been drawn by my neighbor's three year old daughter) all blurred, and being unalble to zoom into the schematic you will certainly agree that it seems pretty useless.
OK for a general overlook, but not OK for any enthusiast to try building it. So why not add a clear drawing like a PDF file?
Talking about schematics it is very important in my opinion to label nets to a great extend to make the schematic readable even to newcomers.
I once studied the schematics of a japanese EE who introduced a frequency counter to 2.4GHz. There was no missing or misleading information throughout the seven pages of the project.
For comparison: I also studied the schematic of a 500VA-inverter published by a German electronic magazine. Not only it was full of net errors (which are unlikely to happen if nets are labelled), but there were 10pin connectors on the PCB which didn't appear in the schematic. To build such a design it requires not only skill, but also some kind of reverse engineering.
Kind regards
Hans
