Hi all, I'm new and am also attempting a GSSL build - and I am very clueless about electronics in general (there, I said it out loud).
I used the Gyraf BOM as a starting point, and it was perfect for most of the simple components - but when it comes to more complex components, I am currently unsure of how to proceed:
For example the THAT2180 comes in 3 varieties that I can see - A,B,C which have different charactaristics (see page 12: http://www.thatcorp.com/datashts/2180data.pdf).
As another example, there are many more varieties of and vendors of the LM78L12, LM7815, LM7912 and LM7915 (AC, ACZ, ACZ/NOPB etc...)
Finally some components are (to me) very vaguely specified: for example "1pcs Bridge rectifier, Round type, 1A/50V minimum". A search for "Bridge Rectifier" comes up with a lot of hits - and I can usually find "1A/50V" but the other properties are extremely variable.
I know that exact BOMs go out of date, as manufacturers and distributors change part numbers - but I would be very grateful for some clarification at least on the above listed parts.
I have already purchased the resistors, diodes and capacitors - and I think I have made the correct choices (the resistors were easy, but the caps had a lot more choices). I can post the BOM if anyone is interested in helping me determine if I purchased the right stuff, or if they just want to see whats there.
Thanks in advance, and I apologize for my first post being an attempt to extract free advice from everyone
Peace,
