This video shows an overview of how I converted a Hornby Deltic to radio control. This allows independent operation on my DC layout.
Happy to answer any questions and to provide procurement details if asked.
PARTS LIST
Micron MR603 receiver prewired (I found I had to manually add 4 wires)
Micron 3S switch/charge assembly
DF Player MP3 player with SD card (see more below)
2 Reed switches
1000mAh LIPO 3S battery
12V to 5V buck (the one I used was anything from 30V to 7V input with a 5V output)
LP2950 3.0V LDO regulator (provides 3.0V to the TrainTech SFX sound module instead of the battery supplied)
TrainTech SFX module (diesel); make sure this is positioned such that the little wire and sensor are free to detect movement
12 bistable relay
3 S9014 NPN transistors (these are good for the purpose as they are high gain)
“Sugar Cube” loudspeaker
Resistors (all 1/8W as small)
3 1k
1 3k
2 4k7
8 10k (value controls LED brightness, you may want lower value for more brightness)
2 100uF 25V electrolytic capacitors
I mounted the LED current limiting resistors and the 100uF capacitors on the loco cover. This means only 3 wires to connect being +12V and 2 wires that get taken to ground depending on direction of travel.
DF Player:
Refer to data sheet on line.
It is operating in a simple mode such that there are 5 MP3 files in the root of the SD card
It is file 1, 2 and 5 that get played; it is important to copy 5 files across to the card in the correct order (files 3 and 4 must exist but are not played). File 1 and 5 get played if ADKEY_1 or ADKEY_2 is taken the ground. File 2 is played if ADKEY_1 is taken to ground via a 3k resistor.
It is best to set this up on the bench and ensure it does what is wanted.
MR603 receiver:
This needs configured using the TX20 transmitter.
Changes I made from default were:
PWM frequency set to 120Hz
FA / FB set to “front” and “rear”; these outputs close to ground when to indicate direction and operate the front and rear lights.
FC set to CH5 (bind button) latches to ground to toggle the SF on/off.
FD set to CH2 low (F1 button); this powers the relay coil that switches the unit off
P4 set to reflect the CPU LED on the receiver and operates the LED built in to the switch / charge assembly via a 4k7 resistor.
P1/P2 set to CH3 (this is the toggle switch); this sounds MP3 files 1 and 5 which are the two tones of the horn.
P3 set to CH4 low (button F2) to play file 2 which is a flange squeal in my case.
As with the MP3 player, this is best set up on the bench with breadboard connecting the outputs to LEDs to indicate their status.
The F outputs are active low and float when inactive so the LED anodes should be taken to +12V via a 4k7 resistor; cathodes to the F output.
The P outputs are active high and rise to about 3.3V so the LEDs should have cathodes on 0V and anodes to the P outputs via 1k resistors.
