Universal led DVD laser driver

DVD laser pick up hack can be found all over the internet, others use the linear type laser driver that uses LM317 as the regulator for the laser. Actually laser is also a type of diode that emits light and with the use of a focus lens, we can attain just a dot for it to be called a pointing light device.

 Shown on the left was the constant current driver on my previous post about led driver. This Buck converter can supply up to 700 mah constant current to a high power led of 3 watts. The heart of the circuit was NCP3063 made by On semiconductor.
I made two of them one will drive the high power led and the other will drive the DVD laser for this hack.

Since theres no documentation of the maximal current a DVD laser must have, I made one with a 1.5 ohms sense resistor, and the other with 1.8 ohms, both differ with current that will provide to the led.

The forward voltage of the led will just float when the CC driver is connected to the load.

R203 and R202 will determine the current output of this driver. It is very important to calculate it for your led, if you know the specification of your high power led.

NOTE: never power up the CC driver without load. the NCP3063 will be damaged.

The test show a 3 watts cool white led connected and the CC driver is powered by a 12 volts AC adaptor.

The actual current being supplied to the led is actually 370mah..(forgot to take picture with a ammeter connected in series with the load..next time :)....)

With the same LED CC driver, a blue high power led is connected as shown below.

The led being tested here actually have different forward voltage drop and according to their datasheet.

and now to test if this led CC driver will power up the DVD laser,

cool yes it can be powered by this driver. I am thinking of the LM317 before but i wanted it to have a wide input voltage range.

shown below is the test, inside the black tube was the dvd laser

ONE chip spinning POV

I was inspired on a site where they make those spinning POV (persistence of vision)  that scroll text from right to left with just  8 pieces of RGB led. What's good about their version was, few components used.

HERE is a working video of my version.

As of this time, the text scroll too slow, and i am just beginning to configure the RPM of the motor to make it faster.

Some photo of how i made the hobby project.

 materials i made for this HOBBY project. the smd pcb, controller and the smd led.
These are the smd led from a CHINA made led strip. Just needed to resolder this and reuse to my own pcb. I needed to use a low wattage soldering iron around 20 watts, for the first attempt on removing this was terribly difficult, I actually waste 6 pcs of them by to much heat of my first 30 watts soldering around stripping the internal contact of the led to the pins...what a waste, anyway i do manage to salvage at least 8 pieces for this project.

Shown on the right was the populated SMD pcb with led in placed. mount all the parts on the controller board such as 40 pin ic socket, ICSP pin, resistor.

combine the two boards, SMD led board and Resistor board with copper wire strip from a donor telephone wire..

When all board been populated with components, its time to solder the thin wires to their corresponding pins.

All of them are inspired to be made through this link


Thanks to you.
