Title: Im confused: firebomb components
Post by: micahdunn on July 19, 2011, 09:57:17 PM
ok, ive done a few diy projects, but i just got my first madbeans project and im very excited about it. but im a little confused on some things about the components. its the firebomb, ok, first: what is a 100R resistor? i bought a multi pack and it has a 100 and a 100k, is it the 100?
second: where can i find a 100n capacitor? and i found a 10uF at ratshack but cant find them anywhere else. all i can find is mf and pf. is one of them the same as uF?
third: why is there a B and C after the pot values? somthing special? and whats the difference in liner and audio taper?
i apologize if these are things i should know but most of the projects i have completed were parts included. this is the first one where im collecting parts and im still learning what it all means. i appreciate any help.

For your question about pots check out BevisAudio(http://www.beavisaudio.com/techpages/Pots/ (http://www.beavisaudio.com/techpages/Pots/))   A picture is worth a thousand words.

Yes the 100R in 100 ohms. The R is used to clarify that it is ohms and not a forgotten M or K you also may see E used  instead of R.

100n(nanofarads) is .1mf or uf. mf and uf both denote microfarads. If you need one pm me your address and I can mail you one.

Good luck with your build.

Here is a conversion chart that will help in future builds as well.

For some reason some places still use mF to designate uF.  Small bear for does this for example.

I don't see the letter C on Beavisaudio but that designates reverse taper.
So A=audio.log B=linear C=Reverse
