  1. For this project only, the cost is under 10$ in parts but you need to buy minimum qty of each item so you need to spend more $$$ for man/hours.... $$$$$$ it take alot of time. equipment... $$$$$ oscilloscope, development board (for microcontroller), soldering iron, laminator(for pcb), tools, ect... so if you start from nothing and you want to build a project like this you'll have to spend... 500$ and over ;)
  2. Thank you for your comments! The leds are smd 0805 (2012 metric): 2.0 mm × 1.25 mm (0.079 in × 0.049 in) the current of the leds is about 20ma max The only things you need to built a simple lighting system is: 38 gages magnet wire (i bought it from ebay) 0805 smd white leds (ebay) (white led = 3.4v so at 3v its ok! other color don't have the same voltage so you will need resistors) you need a 3v source (2x AA size battery)
  3. there is 2 leds one behind the headlight and on on the side behind the signal flasher I would like to but there is a lot of R&D involve and I have not enough money and time. But I'm still thinking about it! the wire are about the tickness of paper sheet. 0.003" thick
  4. Hi Here's my new project! I've add leds to a city model with IR remote control. Here's are the result: Look on 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!
