Just wanted to let you all know that in the upcoming days i will be working on a homemade Arduino based remote lcd head for Uniden DMA scanners. If anyone would like to be a part of this project with me then please send me a PM. Im not looking to take this to market but i do want to put the plans online or on here so people can make these and use them maybe make them a kit

It will function just like this but with 2 knobs (vol & squel) and 1 big dial and of course the LCD. The whole unit will be about the same size as a deck of cards. If anyone wants to do this with me than please let me know

This is not my video its just for ref
YouTube - 'Bearcontrol2' Uniden Scanner Remote Head

Thanks
Mike

Well I sure would be interested to help out in any way I can. I don't have too much knowledge about the arduino tho..... :/ ....maybe I can help test out in some way?

I would love to help out..I have the following Uniden scanners that I can test on:

996xt, 396xt, BCT15, 15X

Hi,

I wouldn't mind assisting if I can. I have worked with the HD44780 displays in the past for my own projects. I have not work with Arduino, but would be interested in being introduced to it.

I'm excited at the possibility! I love the older scanners that i have but nobody makes a remote head kit for them anymore. Mainly my BC796D and BC785D.

I got the breadboard and the lcd and the jumper wires im just waiting on the Arduino uno. I'm also working on the the code for serial comms to pass to the lcd and all the button functions and dials.i also have to find a box to house this all in. When i get the rest of the parts i will start post my code so we can hopefully works on this as a group project.

Here are the parts i ordered.

Arduino Uno
Arduino UNO (ATMEGA328P / ATMEGA8U2) + Free USB Cable | eBay

LCD Black with white text
Character LCD Module Display LCM 162 1602 = HD44780 | eBay

10k pots to control the lcd contrast
5pcs B10K Potentiometer Pots Shaft S 15mm 3 pin/ Feet | eBay

Just need help finding a good box to put this all in.
Total cost so far $30.50 shipped to my house.

Here is the code i will be using and tweaking to pass serial data to the lcd


*/

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup(){
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// initialize the serial communications:
Serial.begin(9600);
}

void loop()
{
// when characters arrive over the serial port...
if (Serial.available()) {
// wait a bit for the entire message to arrive
delay(100);
// clear the screen
lcd.clear();
// read all the available characters
while (Serial.available() > 0) {
// display each character to the LCD
lcd.write(Serial.read());
}
}
}

What are the measurements of all the parts and how many of the pots will used? I could look at some boxes and see what will work. remember some people might want 2 boxes, 1 for the display and 1 as the control box or the all together in one. I sure we can figure it out, come up with some ideas. To me you are doing the hard part, the programing and that to me should be the only thing you should worry about.

Wow, that is an awesome idea! I will be following this too. i Wonder if the same can be done for the GRE's or does the scanner have to be DMA based?

here are the board sizes. Im going to start with 1 box to hold everything to start (lcd, pots and 2 buttons and a spin dial) after i work out all the kinks i will try to make it more customized. I still have to workout the serial from unidens protocal to the arduino. GRE and anything else i would consider but im doing uniden first. Keep in mind this is open souce and a group project not just me.

Board size is for the UNO off of this site

OK, I have the measurements and rounded up to the nearest half inch:

Arduino - 3.5 x 2.5 x 1 and LCD - 4.5 x 3 x 1

I found a enclosure just for the Arduino at Amazon, but for 14 bucks I will pass:
Amazon.com: Arduino Project Enclosure: Electronics

This one is off of eBay for $5.50, this could house every thing, it's big and roomy. 8x3x1
Black Plastic Electronic Project Box Enclosure case | eBay

Rat Shack has a smaller one, 6x3x2
Project Enclosure (6x3x2") - RadioShack.com

This is just what I have found so far, open for anything different. I'm sticking with a plastic enclosure and not metal (aluminum) cases.

I think it is great that you will be releasing the plans so we can make them ourselves. I remember watching that "BearControl2" video a couple years ago and have always wanted to make my own ever since.

I never had much interest in the Uniden RH96 as it is the same [front panel] size as the mobile/base DMA scanners. Having a separate screen and minimal controls would give people a lot more installation options (especially for custom vehicle installations).

I don't think finding an enclosure for it is all that important. I think many people (myself included) would rather separate the components to work it all into a custom installation.

:)

Agreed, I never had much interest in the Uniden RH96 either. It was to big and stuck out like a sore thumb if put in the car.

I think 2 boxes will be better, for me, someone might want to have it all in one. I might even go and make 2 of them, one all in one and 2 separate boxes. When xeno194 gets the programing done it will open up a lot more possibilities. Just like what KE4NYV did with making his cat5 adapters for the RH96.

Looks like im going to tap off the back of the uniden desktops to start than goto the handhelds. Im going to use comport pins 2 (Transmitted Data)- 3 (Received Data) and 5 (Ground). I Don't know how important 5 is going to be. Im going to start with the scanner passing info in 1 direction to the Arduino pins tx1 rx0 and have them goto the remote lcd soon as i know all of it works i will start coding for custom buttons in the project box and take it to step 2. Im at step .05 :) right now.

I have made some progress here are the ascii codes to send to the radio. I just need to translate button pushes to ascii via Arduino and getting the loop funtions for the lcd calls


:) This is starting to make a lot more sense to me.


4 BUTTONS FOR VOLUME
VOL,5[\r]
VOL,10[\r]
VOL,15[\r]
VOL,20[\r]

1 MUTE BUTTON
VOL,0[\r]

1 BUTTON HOLD/RESUME
KEY,H,P[\r]

Send the same key for both funtions

KEY,H,P[\r]

2 BUTTONS FOR SCAN

Scan Up
KEY,>,[\r]

Scan Down
KEY,<,[\r]

I think im going to have to convert all these command strings (KEY,<,[\r]) to DEC or HEX format for the arduino to understand them and save memory. That part is going to be a PITA.

You be coming off the GPS serial port or the front one. Will this require a serial plug that will split, one to the GPS and one to the Remotehead. Just asking as I could look at doing a serial plug design for you.

Im going to go off the GPS port first than work on using the front port when i know it all works
