  • Purchase single relay?

    I can only find packs of 10 on the web site. I don't need anywhere near that many.

    Well then, find a site or a shop with the quantity you desire.

      You're right, I should take my business elsewhere.

          I was hoping to get one that already had the 3 pin connector already on it. I haven't been able to find them anywhere. Thanks though, I didn't know the relays were that easy to find.

            You can get the pin header connectors and pre terminated wires from http://www.pololu.com/ very cheap... More than you will ever need! Then just wire em up to a standard relay, or the appropriate size relay for your project.

              Only 3 pins... Good - common power saves a wire.

              Lucky I didn't answer for 4 & 5 pins relays....

                Thanks I didn't find any 3 pin headers with the wires on them, but I did find the single pins with wires on which will work just fine. They are on their way . Thanks again.

                I'm not sure what you mean. My original post was asked because they did used to sell single relays.. On top of that their website store appears to have moved. If you click on the "Sensors and Input Devices" link under "Categories," it doesn't show anything. However if you click the store along the top navigation it takes you to the new store which appears to be integrated with mp3car.com. where there are sensors. So please, OldSpark, forgive my ignorance for not knowing any better on where to find these things. All I know about them is the ones I bought from the original store do exactly what I want.

                  There aren't many 3-wire relays - they tend to be too dedicated.
                  4 wire is the commonest for SPST.

                  I wouldn't expect people to know where to get components.
                  What surprises me is that people that know the jargon (relay) and have web access can't search and find out...
                  But web info is getting worse!

                    Thanks for that link. I refuse to order from Mp3Car.com anymore on principal over them profiting on shipping charges. $$$ amount isn't important I'm just fed up with retailers thinking I'm an idiot charging 200% of the actual cost for Canadians.

                    When I called them out on it and linked them to USPS documentation showing they were BS'ing me, they just stopped replying.

                      Must be the extra handling necessary for you Canadians... lol

                      Personally, I buy most of my carpc stuff from Chris at mo-co-so. He's really flexible with shipping and has no problem getting on the phone with you to answer questions, choose a different shipper (even if not available on his website), etc. It's too bad he doesn't carry much (if anything) in the way of sensors for FB.

                        Also, to the OP. They do have the 3pin with wire, just cut off the other end. http://www.pololu.com/catalog/product/2169

                        That is who I just ordered my screens off of.. Mp3Car lost out on that order because they tried to gouge me on my small order.

                          Ahh. I saw that and thought it would probably work, but I was able to get the singles for quite a bit less. I can just cut them in half and then just solder the bare ends to my final cable. I agree with mp3cars prices being ridiculous. The photosensors for the brain are $14.99 that's highway robbery (let alone what shipping would be). I ordered 5 of them for $1 a price of adafruit.com. I just hooked them up and they work just fine (well as soon as I dug up 10k ohm resisters ). Now to figure out how to get if then's working..

                          Edit: Got the if then's working. The UI makes things realllly nice.
