Dvhw - re "get rid of that damned termina blocks and replace them with square pins":

One of the advantages of sticking to 0.1" pitch is that it's really easy to substitute less expensive headers if the terminal block aren't all needed.

wow that is a tough call. I used one of those at some point and liked the convenience, but man that cost is offputting.

@TonyTip: ...It's worth paying a bit more for something if you like it better.

Once again, I don't disagree :-)

@TonyTib: ...even $2.50 for 10 pos is $0.25/point -- a reasonable price if the quality is good...

I agree ... but I cannot help but dream (it's one of the things that makes me so endearing LOL)

Max, come on, ~$1.00 is $0.10 per connection point; even $2.50 for 10 pos is $0.25/point -- a reasonable price if the quality is good.

To get cheaper, I'd say look at going to 2.5mm for the TB (probably cheaper to go with more positions) and look at Phoenix's building oriented stuff (the various PTxx lines) -- in fact, I'd recommend ordering (or begging for samples) a few to see how you like them (for example, the $1.07 PTSA 0,5/10-2,5-F is spring clamp)


It's worth paying a bit more for something if you like it better.

@jstabler: Buy fours and fives, then mix and match. Cheaper and you may need enough to get a Digi-Key quantity discount.

Clever ... especially if we can find somewhere to source them at 25 cents a piece LOL

@dougwithau: Figure out who is the local sales rep in your area.

I couldn't bring myself to do this for a one-off hobby project -- my mom would be dissapointed in me (and she's know ... I don't know how, but she'd know...)

Re: 0.2" connectors

@antedeluvian: You could use 2 rows of 0.2" spacing connectors one set back behind the other and offset by 0.1" (with 45 degree input angle). I could help you source those!

But then we'd have to re-spin the board -- I can make do with just one of these shelds for my current project (although I would build a bunch if we can get these connectors cheaply enough) ... but thinks for the offer.

@TonyTib: I did a quick Digikey search, and found some fixed 2.54mm TB's for <$2.50 (the OST ones).

Wow! Thank you! I have to admit that I often end up in a bind using the parametric part searches on these sites...

Now, if we could only get the price down to $1 or even $0.50 each....
