Thanks. I just talked to Mouser support and they said I could use them as jumper wires, but I was confused why they would even be made. I'm just starting out with electronics and they seemed pointless to me, but I'm sure there is a reason they exist.


Sometimes you have to fool the pick&place machines...

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Darn things just refuse to work with leftover lead cuttings.

Well I just ordered a box of 1,000 of them. I think they'll be neat to play around with on a few projects. I've been looking at several websites and I can't find many places aside from Mouser.com that actually sells 0 Ohm. I contacted another company and they told me that 0 Ohm resistors didn't exist.

I got all the parts to make those Throwies too. Those look kind of neat.

Edit: So how come I don't need a resistor when I build a Throwie?

So the negative resistors is how they make alternating current?  :smiley-mr-green:

Apparently you can get the 0 Ohm resistors in +/- 1% too... Just in case...

Well actually yes!  :smiley-eek:
Negative resistance is essential for an oscillator to work.

From a capacitor or inductor perhaps?

Your sketch can sense ongoing process events in time.
Your sketch can make events to control it over time.

Well that is the only real way to get it. I have sifted through hundreds of zero ohm links and not yet found one on the lower side of the tolerance range.  :)

Along with zero ohm links professionals use no fit components, for features they might need.
This lead to one occasion where in a schematic review six engineers spent over fifteen minuets arguing about the value of a no fit component until I pulled rank and stopped the conversation.
