Re: edge connectors vs. terminal block - My Two Cents

Puckdropper
 

If you replace the leads with the copper traces on the PCB and the terminal strip with screw terminals, you've basically got the solution I brought up.

However, there are areas where wiring such a tortoise would be difficult at best. (Especially if you use a screw terminal that tightens from the side.) In those cases, leads to the terminal strip would probably be a good way, especially if upgrades or changes are planned.

In such an area, I'd probably wire the tortoise first, then go about installing it. If I thought I'd need the switched terminals later, I'd probably drop leads and simply cut them to a reasonable length.

One issue with dropping leads to a terminal strip is that it takes up space. In one area of the club layout, there's wiring for two levels, plus the switch machine controller, a staging yard, signals, and Loconet (and more) all passing through a 2' wide section of layout. Dropping leads to a terminal strip would just add to the clutter.

I agree soldering to the tortoise after it is installed can be a problem.

Instead of an edge connector or some other Rube Goldberg contraption, why
not wire the Tortoise with leads, then to a terminal strip or to an 8-pin
male/female connector?

The thickness of the PCB board is undesized allowing
a lose mechanical connection. The board does not have tight fit like a
Digitrax board has in it edge card connector for reference.

If you take a look at the guy's web page, he suggests three Digikey part numbers. Even if you don't order from Digikey, it's worth looking up the parts to get the exact specs.

I'm not a hockey ref, but do play one on the bench (as we all do *g*). "Puckdropper" comes from a time when I was too young to skate in my dad's league, but they could let me drop the puck after a goal.

Re: edge connectors vs. terminal block

I actually just ordered the parts that the website said were compatible. However, out of curiosity I did go out and measure. Inside-to-inside was .141", while outside to outside was .192". That means an average (should be close to center-to-center) of .160".

The connectors I bought were a little tight (.138") but not too bad.

I use these terminals on my decoder boosters. They are really nice and
easy to trouble shoot: Here is a cheap source:

http://www.goodluckbuy.com/2-pin-screw-terminal-block-connector-5mm-pitch-100-pcs.html

They also have 3 terminal blocks. And they all dovetail together. I
think the photo shows them at a slight angle due the the holes in the

straight.

Re: Wiring Tortoise for turnouts, switches + LED's

David Klemm
 

Richard;

You will have a wire from the switch going to tab 1 and another wire to tab 8. Pick one side and put your LED and resistor in line. When you power it up it may display the wrong color, if so then just flip the legs of the LED.

Yes, correct & I'll add for clarification (it may may modify your responce) that the bi-color LED will be on both the layout itself, next to the turnout, AND on the control panel board.
Looking forward to your reply. Richard

If that is correct then you put the LED in line with one side of the switch between the switch and tortoise. Use a DPDT without center off.

Thanks to all of you who have recently provided great infomation about my

Now I'd like to know which Tortoise terminals to wire to switches & LED's...

1) do I use DPDT (with or w/o "center OFF or ON") or SPST, OR ?????
2) which wires on the switch get wired to which Tort teminals?
3) I want to wire LED light (bi-colored) at each turnout. Can I wire each

As a fastening alternative, I sometimes use the velcro strapping
available at garden centers for plant ties, stapled to a convenient
location under the layout. Makes for a very simple, expandable hanging
system.
