You can order them online from sites and distributors such as Digi key or Newark.

Yeah, your best bet is to search online.

There used to be a member here who would mail you 10 for the cost of shipping but he was :banned:

Guys, he should look at a local store first.. No point waiting for mail if you already can get them directly at a local electronics shop..

I don't think I've seen them in Radio Shack unless you buy an assortment of 500-something.

For reasons still beyond me. This forum is not the same without Jerry. It's not the same at all anymore actually. :undecided: Most of the old timers are no longer here.

Here's where I ordered my last batch. Though I used our wholesale account so they were a hair cheaper.

1 Ohm 5W Resistor | Parts-Express.com

They have 1% tolerance ones individually as well, but, the price increase is fairly steep over the 10% ones.

I could sent you a few for postage cost only. I have to wait for the complete E12 resistor serie coming from China. That is 8500 pieces of resistors

Maybe 2 resistor of 2Ohm in parallel for more load balancing or 3 of 3Ohm.
Just one 1Ohm resistor will get very hot at high current and the measurement is not reliaiable.

I've never had a 1 ohm 5W get warm. Setting driver current shouldn't really be something that you have to run the test load hours to do.

^Or need an accuracy of 0.001% for that matter.

I use 1/4Watt metal resistors.

^^^ Yeah me too. I don't need to measure for more than 4~5 seconds....
