Re: I hate those terminal blocks

For prototyping, it really doesn't matter -- I don't typically bother with ferrules or such, and I'll happily scrunch multiple wires onto one terminal.

For production, we use crimped ferrules when inserting wires into screw terminals.


However, with spring clamp, you just strip and insert (nothing else required), making sure that ONLY the stripped wire is inserted (since, of course, if your spring clamps on insulation, you get no contact).  Also, I wouldn't trust doing multiple wires to a single spring clamp terminal.

IDC is the easiest: insert the wire and close.  However, your wire & insulation must be the right size for the terminal, and I'm not sure I'd trust repeated use of most IDC terminals (maybe the swing-style ones are better).

At a minumum the ends of the wires must be well tinned, you can also crimp or solder pins on the wires, as long as the pin's size allows insertion.
For prototyping it is easier to undo/redo one wire with screw connectors than by using block connectors.

@TonyTib: To be fair, I've had good luck dealing with Stationary Art in Hong Kong (I got my superb Kuru Toga Roulette pencil from them at a great price), Seeedstudio (Arduino stuff), and Gold Phoenix (PCBs - good if you're experienced but they don't hold your hand).

I like the stuff I've used from Seeedstudio, but they could really do with someone in support who can read and write good English LOL

@Crusty: I have got my Microduino Kickstarter boards through the post yesterday, all I need now is to get the builders out of my workshop, so that I can write a blog about using these minature bits of kit.

Cool beans -- I look forward to it

@Crusty: Hi Max, Have you seen this Kickstarter project for custommisable boxes for Arduino and other form factors? click here.

That's a nice little project -- I wish them well

For work, I pretty much specify Phoenix because the quality is good, availability is good, they have a very wide range, they have 3D models, and the price is OK (especially since we get a good discount from our local distributor) -- and I try to choose the more affordable ones.


For my own use, however, I'm more price sensitive, so I have a mix of Phoenix, OST, Wago (from eBay), and some unknowns (from our local surplus shop, Excess Solutions, which sometimes has Phoenix at great prices).  The OST seem well made, too, but the plastic does have a different feel (maybe not worse, just different, although some of my "unknowns" don't feel as well made).

I can't comment about Aliexpress or Hong Kong vendors, other to say that Aliexpress doesn't seem to have good customer service (surprise, surprise!), and that I have some some (non-Electronic) made in China items made of cheap, stinky plastic -- and the stinky smell doesn't seem to go away, ever.

To be fair, I've had good luck dealing with Stationary Art in Hong Kong (I got my superb Kuru Toga Roulette pencil from them at a great price), Seeedstudio (Arduino stuff), and Gold Phoenix (PCBs - good if you're experienced but they don't hold your hand).

Hi Max, Have you seen this Kickstarter project for custommisable boxes for Arduino and other form factors? click here. Only a few hours to go before the funding stops, but the stretched goal already reached.

Wet weather still causing problems in the UK and it seems like Crusty Mansion is at present an epicentre.

Best

Reader Fredrik Nyman emailed me to say: "Aliexpress.com has several vendors selling them for less than a buck (8 pin version) and their minimum order quantities are reasonable (10-20)."

@Jgrubbs: I found 10, 9 and 8 terminal 2.54mm screw terminal blocks on ebay

Wow -- this is wonderful news -- for some reason I never think of looking on eBay (which is strange considering how much I've bought there) -- thanks so much for this
