Uniden Remote Head Project

Hmm ok. Probably a dumb question but did you solder those wires into the Teensy?

Also, it looks like your display data lines are on the wrong pins. They should be closer to the main chip on serial port 3 Teensy pins 7 and 8.

One of my test units.

no just using the wires with the pins.

Yea you can't rely on that for a decent connection. Or, at least hold them together and push them to the side with a bit of pressure with your fingers while you hold them in place or something to make sure they are making connection but I always solder them or use the pins like in my pic. You end up fighting yourself with phantom connection issues. Get yourself one of these and a soldering iron if you don't have one.

Amazon - Dupont connector kit

I say we back up, start from square one. Load a test sketch of some sort to make sure you are at least able to see the Teensy print something to the debug serial port. Once we know it's alive and kicking then we will work from there.

Ordered that kit. Thanks for the help. Enjoy your weekend!

Thanks, you too.

Also, here is the crimper to make your own wires.

Ok, all of the parts have arrived, including the new teensie without pins. I can solder the pins on to match your picture above. What are pins 10 & 11 for? And the additional 3.3 volt pin and ground pins for? I'm guessing thats where you're connecting the gps.

If you're going to solder the wires anyway, why not forego the pins and solder the wires directly into the pin holes?

I could do that.

9 and 10 are TX/RX Port 2 for GPS. I was just making 3.3v available to test to see if I could drive the GPS with it.

I got a case of 67 gray project boxes that fit the displays really well once a window is milled into them. I'm experimenting with the best way to cut them with a small CNC.

mancow - I apparently don't have enough posts to private message but depending on what kind of plastic those boxes are, I have a laser that might make short work of cutting your windows very precisely. I've cut display windows and miscellaneous port openings in a number of ABS project boxes. You're in NE Kansas and I'm on the north side of Kansas City. We can't be too far apart.

Interesting! It's ABS plastic.

I'll see if I can send you a message somehow.

I'd like to thank mancow for all of his efforts in getting this project working and the time he spent with me resolving the issues I had with the power and serial ports. I finally have a working product.

Was it worth tackling your self or better off attempting to purchase a premade, plug and play version?

All depends on your abilities and the ability to purchase the components. I'm not an expert with soldering, or a developer but I was still able to following the posted directions so far. Once a case becomes available it will be finished. But it works now.

Anyone have one mounted in a vehicle yet?

 

[jpjohn]

Any idea when a complete build will be available to purchase? I'd try to build one myself but not sure I have the knowledge or skill that you guys have. But very interested in a remote head possibility for the SDS series.

I guess I'm one of those plug and play type guys!!!!

Any updates? Really looking forward to this!!

It’s alive!

Had a Nextion 5" display but decided to wait until I had the 4.3" display. With the Coronavirus and Chinese New Year, it took forever to get.

Looking forward to stuffing this in a case with a GPS. I've got some small GPS modules which can be used for this project.

Thanks @mancow!

I have also attempted to build the remote display. Programmed the Teensy and the display, wired everything up and connected my SDS100E (EU version).
The scanner is recognized as far as I can see and the Teensy seems to send the command to put the scanner in serial port mode.
The display shows the first screen (Uniden Japan SDS100E ) and then the next screen with In memory of Paul as shown in the attachment pops up.
After this the display doesn't change anymore. But the buttons on the screen do work, I just can't see them.

Any thoughts on what could be wrong with my setup?

I know there have been several revisions of the remote head project. Is there one better than the other and if so, is there a parts list with instructions?

User error, ofcourse...

Forgot to change setting to Optimization: Fastest + pure code with LTO when writing to the Teensy.
Now all is good.

Printed a nice enclosure and mounted the Teensy and display in it.

Big thanks to Manow for all his effort.
