how to make a homemade led light for your motorized bike

Hello dear readers , in this post I 'll teach you how to operate a LED lights 100 % made ​​by you on your moped , with or without dynamo :
Let's start the list of materials:
                    -16 White high brightness LEDs ( home electronics )
                    -4 Diodes 1N4007 or equivalent ( house electronica)
                    -1 1000uF 16v electrolytic capacitor
                    -1 50 ohm resistor 1/2 watt
                    -Cable 0.25mm long to election, more than two meters insurance depends on your BM
                    - One or use the dynamo generator engine failing
                    - One welder and tin
                    - Plate for electronic design , can be epoxy or fiber can buy that is already perforated plate or virgin :
                                    a) if they buy the perforated plate saves buy the acid ( ferric perchloride , the role of thermal Domain Transfer saves , but it is a little ugly if we would do the most professional way , but it is easier .
                                    b ) if they choose to do the hard way will need :
                                             ferrous - ferric chloride (comes in a bottle , is an acid , beware )
                                             - Paper thermal transfer or an indelible marker
                                             - A plate to transfer the pattern of the thermal paper to the transfer plate .
                                             - Laser printer or copier.
                                             - Cheeser and 1mm wick

Once we decided to do and we have all the materials we start with :

1) we print the design on paper thermal transfer , read well on paper which side to print not to break the printer, because if you put the other way around the paper has a resin that can damage your machine.

design is as follows ( do not print this picture , and they will go out of range , now leave the link where I should download ) :
               
                 
                        board                                                        front view

2) Once you print the pdf and this came to scale, must pass the drawing sheet to the plate with an iron should be at a temperature of around 100 ° C, if they are going in the cotton picker mode. I leave a video to learn how to do it:

3) After that must happen to chemical attack by ferric perchloride, I leave a video of that too: 

Do not need to water bath, but this accelerates the process a lot

4) After that we do all the holes in the plate with the wick of 1mm and a drill, they should do very carefully to avoid breaking the plate is simple, holes are marked, do not think I need to explain this . 

5) After holing palaca should proceed to put all the components in the following way, as shown in the image recueren the long leg of the LED and the capacitor is the positive, always respect the positions of the image must be placing of one and welding it with tin and an electric welder, the first thing that is resistance welded, then the diodes, leds and then finally the capacitor:

6) Once all placed and welded two wires should be soldered to the islands, or terminals that are between each diode, these are the inputs from the generator or from the black and white wire motor, the position is irrelevant, since this board has voltage rectifier and filter, which will allow the LEDs do not blink or burn. 

7) Then can give a box of plastic to keep it dry, and do with pedasoz tambienpueden mirror or aluminum foil plates that reflect light from the LEDs to focus more and concentrate light.
