Your Teensy setup

[kurt-olsson]

I am using teensy as controllers.
I am having a real hard time to find a way to get permanent good setup with cable connection.

I bought a crimp tool and using dupont, but i am not getting solid connectors.

I also need multipla connections for ground and voltage in. Some kind of breadboard or ground rail.

How are you people doing when working with teensy?

Look at this try (mess)

Yikes!

As you're finding out, that wire thickness will never work.

For these small controllers and mostly everything in my cockpit uses wire-wrap wire.

Here's a demo video I made. While it doesn't showcase the wire-wrapping job, you can see how dozens of wires going to the Teensy is no big deal.

As you can see, I breadboard my circuit first, then literally replicate that design onto a solderable breadboard using wire-wrap wire.

What the heck is a teensy?

What the heck is a teensy? 

Besides Sliced bread, the best thing ever made! =) (Thanks Rob for introducing me to Teensy)

Its a small affordable powerful controller that has digital,analog and PWM outputs and 5V through USB.

With the Flight Controls LIB and ArduTeensy you are up and running interfacing the x-plane datarefs through hardware in no time! =)

Bingo!


This is exactly what i want. more input for ground and power and also able to solder the Arduino pins beside the board itself! =)

Man, that looks awesome! Thats exactly what i want. Soldered solution for permanent use, but still very elegant and organized! Great job!

I made an exception (bad one) and used thicker cables, but normally i use the thin ones you are using.
But that is the components called that you are attaching the cables to and then soldering it to the breadboard?

AHA you use the wire-wrap tool on the pins directly! then you can solder them to get them permanent i guess!

I have what you need!!  My first batch order of pcb's are on the way to me now.  I designed a Teensy breakout board that accepts uln 2803 chips as well as screw terminal connections!  If you only need 8 hv/hc outputs, you just install a jumper across the pins where a 2803 would be and you have a normal I/O.   I'll post pics,  probably be around 8.00 ea maybe less.

Very interesting! After trying the dupont way and giving that up i want to head out for screw terminals! Would be great to see some pictures.

You don't even need to solder them. Wire-wrap wire is designed to 'bite' into the post corners, providing a near air-tight and solid connection between the wire and post.
