New builder question about BOM

Ok, you got your soldering iron and nothing is going to hold you back, but you have no clue where to start or what to build. There were others before you with the same questions... read them first.

New builder question about BOM

Postby Levictus » 17 Jul 2014, 03:19

Hi guys

New to the forum, sorta new to guitar, and new to pedal building. I do have some electronics soldering experience as I did quite a bit if diy R/C airplane stuff but not with regard to more complex circuits. My question relates to this BOM for a build I am interspersed in:

PART COUNTS

RESISTORS

(3) 1M
(6) 100K
(3) 470K
(5) 47K
(3) 1.5K
(1) 22K
(4) 10K
(1) 4.7K
(3) 3.3K
(1) 330 OHM
(1) 220K
(1) 1K
(3) 150K
(1) 6.8K
(1) 18K
(1) 47 OHM

CAPACITORS

(1) 470PF
(2) 33NF
(9) 100NF
(1) 4.7NF
(1) 100PF
(1) 47NF
(3) 220NF
(1) 22NF
(1) 1.2NF
(1) 100UF ELECTRO
(3) 22UF ELECTRO

IC'S

(3) TL072

DIODES

(4) 1N4148
(2) 1N4007
(3) 1N4733

POTS

(1) B100K
(2) A500K
(2) B10K

SWITCHES

(2) SPDT ON/OFF TOGGLES

So I understand resistances etc, but when attempting to look parts up at Mouser, for example resistors, there is also a power rating to consider. I did some research on this firum and correct me if I'm wrong, but in a 9v circuit, I should be good with a 250mW rating, correct? This pedal can also be run at 18v so would that be a bump to 500mW?

Do you see anything else in here that might present a problem or have advice with regard to any if these parts? Thanks in advance for your help.

1/4W resistors are ok for 18v pedals as well
...and welcome in the diy tunnel!
