I just found I have an assorted bag of resistors that are rated 1/4W. I guess 4 of them in parallel do 1W? PS. Or also in series? ..if they are identical I guess. |

I'd better do it with at least 5 identical then if I attempt it. If the design failed for that it wouldn't hurt to be more dissipative. (then again, it was probably because 1 of them wasn't even connected so ..yeah) |

1WJ means 1W and 5% tolerance. |
| epigramx:
So, I need 0.08Ω apparently since they appear to be in parallel (and 0.13+0.22) but I don't have any around (to parallel) (not even near, those assorted-resistors bags appear to be usually >=10Ω). Would a sufficiently long cable that is exactly 0.08Ω suffice? Or at least if it's not kept right on other electronics.. |
