Power Pigtail adapter

Post by misterz12 » Mon May 12, 2014 11:41 pm

Hi,

Am I missing something or are the instructions on the wiki for the power pigtail adapter completely backwards? These posts on Inventables and the Shapeoko wiki seem to indicate I should order a male plug, which is what I did (the wiki links to a batteryspace page selling the male plug). Unfortunately, it's clearly a female plug that is needed. Argh.

Can someone please confirm that if I order this it will fit?

Thanks,

Zach

Unfortunately, colloquial language has the name of the plugs backwards. What you linked as needing are actually the male end of that plug - you can tell from the, ah, protrusion in the center. HDVD has them labeled backwards.

The 'HDVD New 10pack 10 inch(30cm) 2.1 x 5.5mm DC Power Pigtail Female' you linked are the male plugs that are needed.

I thought it was supposed to be 2.5 x 5.5mm (the part listed is 2.1mm x 5.5mm).

Anyway, I changed the text to: *[http://www.batteryspace.com/connector/a ... -plug.aspx Batteryspace:Connector/Adaptor: 5.5 mm x 2.5 mm Barrel Male Plug] --- apparently this is actually a female plug[http://www.shapeoko.com/forum/viewtopic ... 923#p25922] --- try [http://www.batteryspace.com/connectorad ... ector.aspx Batteryspace:Connector/Adaptor: 5.5 mm x 2.5 mm Barrel Female Jack] which should be male instead (or buy a matched pair).

My apologies for the confusion --- if the part you purchased as male doesn't have a center post, then it's mislabeled and you should be able to get it exchanged for the right part.

Good catch on the 2.1 vs 2.5 mm. I think I would lose it if I ordered yet another incorrect part!

I'm going to order this since it has amazon prime 2 day shipping (batteryspace charged 7 dollars to ship the last plug and it took 8 days).

Isn't that another female plug? Looks like it has a central opening, and doesn't have the central metal post.

(I was looking for a matching part and discarded it from consideration)

Ah, here we are, the perfect part:

male and female extension cord --- one end is guaranteed to work --- which end? I give up. Stupid binary logic.

I've edited the Parts page as much as I can stand --- if someone can find a better purchase link, I'd be grateful.

I'm clearly like the rat in the experiment that keeps pressing the wrong button and getting electric shocks.

I've ordered the part you suggested plus this one, too. Hopefully one of them will work.

As noted, it's a convenience (and one which I mislike since it raises the possibility of plugging the power supply directly into the Arduino and frying it) --- some people have just cut the barrel connector off and wired things up directly.

I've gone ahead and added the part you found to the Parts page w/ a link back here --- please report back on what works and what doesn't (probably the extender cable will be useful in-and-of-itself).

Hopefully, the rest of your build will go more smoothly. Thank you for your patience and understanding.

That's weird; everywhere (including Farnell/Newark, Mouser etc, which I would expect to use the correct terms) the part that usually comes on the power supply is a plug (or jack), and the part usually on the device, the one with the central pin, is a receptacle (or socket). It's true that they don't say male and female -- so maybe referring to it as a receptacle would make it clear to everyone that they needed the receiving end, despite it having a manly pin in the middle.

Yeah, barrel jacks are the only ones with this problem. I honestly don't know why what would normally be the receptacle (female) got the center pin and called male. It ends up confusing as hell for everyone, and caused me a lot of grief when I was trying to find them on electronics supplier sites until I figured it out.
