MOD LEGO City Toys R'Us Truck (7848) with LEDS and IR Remote

jjlkewl69

Here's my new project!

I've add leds to a city model with IR remote control.


Here's are the result:

Look on YouTube

Some pictures:






Modifications:

I've replaced the front of the trailler with some bricks and a technic 1x2 brick to let the wires go thru. All wire from the cab to the trailler pass in a LEGO pneumatic hose.





I've made a custom PCB to decode the IR remote and the signal flasher. The PCB is the same size as a 2x4 plate. I've glued the PCB on 2 1x2 tile to make it LEGO compatible.






The wires are magnet wire 38 "gage" about 0.00397" (0.101mm). They are green on the pictures.




No LEGO parts have been cut, drill or modified. Everything is STOCK.




Thank you for you GOOD comments!

Not really but here's the main thing you need to find:

38 gage magnet wire
0805 SMD leds (mine are white)
2X AA battery (1.5v x 2 = 3v)

to make things flash and remote control you need a PIC microcontroller and it's alot of job and equipment to program it!
