Light Orb Mods

From Zedomax Wiki

First, get the 3 4.7K resistors soldered onto I/O labels P5, P6, P7, and to empty holes as shown here:

Get one of your 2N3904 transistors and solder it on like shown here:

Solder on 2 more transistors:

Solder on 3 100 Ohm resistors to the right side of the resistors as shown here:

You can connect one end of the resistors to the right pin of the transistors as shown here:

Solder on your 4 Red LEDs in series from the 100 Ohm resistor:

Solder on your 4 Green LEDs in series and your 4 Blue LEDs in series too:

You can use one of the LEDs in series pins to connect to the other end of LEDs in series. So connect ground of LED row 1 to LED row 2 and connect ground of LED row 2 to LED row 3.

Splice some wire so it will fit the transistors like shown here and wire all the transistors on the back of the proto-board. This will all go to ground so wire the end to ground.

Solder the 4.7K Ohm resistor coming from P5 to middle pin of the first transistor.

Solder a wire from the 4.7K Ohm resistor on the P6 to middle pin of the second transistor.

Solder a wire from the the 4.7K Ohm resistor on the P7 to middle pin of the third transistor.

Now connect from the end of the LEDs to the DC Jack Positive point, 12V. (We can supply 9 to 24V, but we will use a 12V adaptor here)

Connect a 12V DC adaptor to your Proto-Board and see if it powers up.

Download the program to your CB280. The Program source code is at the end of this HOWTO.

Put a Orb on top of the circuit and you should see colors!

Now if you got to this point and you don't want alarm clock function, you can stop here. But if you want to add the alarm function keep going.
