I'm thinking about building the P16PRO40, and first I'll need to collect the required components, but this is were the problem occurs. In the **broken link removed** it is listed that I need a 78L05, but when I found it, I didn't just found ONE but I found around four different versions of it. ex:
Anyone who can tell me wich one is the right for the P16PRO40 and what the differences are?
I assume that the two-three first letters are the manfacturer the middle numbers/letter (78L05) are the model number and the last letters I don't know what is or mean.
I searched around for the W02M but wasn't able to find it, instead I found the W04M. The datasheet can be seen here, does these differences matter or is it just that the W04M must be used in europa (230V) and both the W02M and the W04M can be used in the USA (115V)?

hmm thanks! but what does a bridge rectifier really do? hehe.. lots of weird questions :wink: And why are there really zero ohm resistors? couldn't you just use a bit if wire?
330pF ceramic (331). I know what the two first values means, but what does (331) stand for?

A bridge rectifer converts AC to DC, basically by 'steering' the positive and negative pulses the correct way - with a DC input it does the same thing, 'steering' the DC (whichever way you connect it) to the correct connections.
I would use a 'bit of wire', but a component insertion machine is far happier using specific shapes - hence the use of zero ohm resistors.
The value is in pF, the first two 3's mean 33 (as you already know), the third value is the number of zero's on the end - so it's 330pF, if it was 332 it would be 3300pF.
Nah. Thats just half-way fun. I think I learn a lot more from actually finding the parts myself, and the when I get it all together, I can say that i built this, just by having a plan, not by using a pre-picked kit. I'm the kind of person who like to do things from scratch, if you know what I mean. And these incredible people at this forum who help me with nearly everything i may ask; your incredible. Thank you! :wink:
