GoldThere has a 16-pin, 14-pin and 8-pin socket.
Align the cut on the socket with the cut on the top-
Side illustrations.
Carefully align the pin with the hole, check that all pins will enter and press the socket tight. Oscillator:-
Find the 20mhz Oscillator and weld it into the OSC.
It has no polarity but make sure it is a good solder joint. Next is the capacitor. The top-
The side illustrations show their polarity, and the black solid stripe is the negative lead. -
Find two 1uF covers that will be welded to C1 and c2.
They do have polarity, with negative leads on one side of the stripe. -
Two 10uF capacitors are placed next. C6 & C7.
Pay attention to polarity again. -
Put a 0 last.
1 uF disk capacitor in C3 and c4.
They have no polarity and can be used in any way.
Wrong part naming, no c5.
The polarized head allows easy insertion and unplugging of wires from the PCB.
The project has a lot of switches, potentiometer, microphones that are not on the board, and there are wires attached to them.
The wires are connected to crimps, crimps slide into the housing, and depending on the change in the kit, more details of Step 6 may include parts or all of these titles.
They don\'t have to, they make things easier.
Without them, the wires of the ect switch need to be welded directly to the circuit board, which makes the installation more difficult.
I suggest try not to use the joint and weld the wire directly to the PCB as much as possible.
There is a note on how the title should be placed on the board.
They have a polarized friction lock so they can\'t insert the switch or voltage input back later. There is a 12-pin, 6-pin, 3-pin, and 3x 2-
Pin head to be welded.
Press them tight, flush with the PCB and start welding.
Be careful not to bridge the solder joints. -The 12-

Pin head for sound input (
Rheostat and microphone)
, It is better not to install these heads and connect the rheostat and microphone PCB directly.
Now that almost all the components are placed, this is a good time to do all the jumpers.
This is used instead of double. layer PCBs. Use some solid-
Line, and look carefully for the route to be followed by the jumper, the path should not cross another jumper.
The jumper is as follows: JA1 to JA2JB1 to JB2JC1 to jc2 to continue to JF1 & 2 * Note: JC4 is a print error and ignores it.
Final jumper: If the output does not need to use a resistor, jump the resistors R3, R4, and r5, and finally place 7805 as shown in the figure.
Weld it well.
If the board interconnect is not used, skip this step.
In order to proceed with the rest of the steps, some interconnect needs wiring.
Part pictures and explanations to start this step, you need to know how long it will take for the wires of various accessories.
All of this is pretty much the same, so I will only explain how to make 6-
Interconnect with the two-strand line.
As shown in. -
Start with 3 double strands of equal length.
6 wires in total. -
Peel off 1/8 of the insulation from the end of the stock.
Crimps must be connected to one end of the wire.
Once you have 6 wires with a curl on each one, I have an external curl graphic page to cover the process.
Buy a house of the right size.
Each curl should slide into the shell and get stuck in it.
They are only suitable for one way.
Just press them until they \"capture\" the rest of the interconnect, power supply, microphone, sound potetimeter, DIP switches are all the same, but with a different size housing.
Starting with the switch, the mode switch included in the kit is a double-knife three-throw, and it needs to jump up so that it can act as a 3-bit switch.
For bracket-
Separate feature selection. -
As shown in the figure, just use resistance clipping and welding. Next the 6-
The pin interconnect of the previous step needs to be welded to the switch.
Reference top-
Side illustrations and the following figure to determine which wires are needed on the mode switch or speed pan.
6-pin head pin output for mode switching 1. Control Pot. Center Tap2. DMX Select3. Auto Select4.
Manual/audio select 5.
Negative, 0 V.
Yes, 5 volts-
Weld the DMX selection, automatic selection, and manual selection to a certain position on the switch. -
The negative pole is welded to the pin on the jump switch, and the other wire is used to extend from the negative pole to the scoliosis ear on the control box. -
The control tank is welded to the center lugs on 2.
5k Ohm panel mount potentiometer. -
The front is welded to the remaining lugs on the control pan.
Rheostat and microphone for sound input control, left side hole for rheostat, center hole is shared between one lead of rheostat and one lead of microphone, right hole of microphone.
Sound potentiometer-
Adjust the sensitivity of sound response-
This part requires the use of a potentiometer as a rheostat. -
An external lead on the potentiometer should be welded to the center lead. See Image-
One lead leads to the Rhine hole and the other leads to the shared center hole. Microphone -
Listen to sound input. -
The resident microphone has two pads, one welded on the microphone hole and the other welded on the shared center hole. DIP Switch -
The DMX address uses 9 locations and the bracket uses one locationAlone Control.
All the locations were pulled.
Together with the 10k resistor.
And \"open\" when connecting to GND \".
The DIP1 on the PCB is positive and there is no need for the dip2 to be grounded, one side of the DIP switch will be connected to the GroundDIP3 is binary 1DIP4 is binary 2DIP5 is binary 4dip5 is binary 8dip5 is binary 16DIP8 is binary 32di9 station-
Separate mode selection. -
There are two rows of pins on the DIP switch, where one/half pins are all connected and connected to the ground (DIP2 on PCB)-
The other line of each pin needs to be connected to the appropriate position on the PCB.
Panel Mount male and female XLR connectors are included in the kit.
Before performing this step, please figure out how long it will take to connect the XLRs.
Pins on connectors arelabeled1, 2 and 3.
They connect as follows.
PCB pin 1 is connected to XLR 2PCB pin 2 is connected to XLR 3PCB pin 3 is connected to XLR 1, male and female are connected the same.
There are 4 ic that can be plugged into the socket.
Align the points near pin 1 on each IC with the gaps at the end of the IC socket. -
Align all pins of each IC with its socket and press hard. -
Plug in all ICs to power things that are more important than a single rgb led, using a splitter board.
Select the board according to the LED settings you want to use.
They are common for resistance regulation-
Anode, resistance regulation co-cathode configuration and constant-
Current adjustment plate.
The resistor Adjustment Board provided is suitable for multiple small LEDs or several high
Wattage led, R4, R5 and R6 are large enough for resistance of 2 or 3 watts.
The mosfet supplied with the board can handle up to 46 watts each.
For very large units, I had a great success with the BuckPlus series constant current regulator.
Please see here when ordering a kit to decide which kit you need or contact us for help.
Test: to test if the PCB is working properly, connect the supplied co-cathode rgb led to \"-R G B\" Header. -
Attach 100 first-
500 ohm resistance in series with co-cathode (
The longest leading advantage)-
Then connect the rest of the leads to the correct header pin. See Diagram.
I built a 36-watt (
12 watts per color)
Use a 3 W monochrome led and one of the drives to clean the lights and several smaller 9 W cleaning lights.
The picture is 36 watts.
In a fully custom case, all user controls are on one side. Some 07023-D-E-700 Buck-
LuxDrive\'s puks provide in-series power for 4x3 watt led strings per channel. A 24v @ 2.
Power all power supplies using 7A PSU.
I really like Buck Parker for simplicity, and they can easily adjust the color of the perfect mixture.
But their prices are on the high side.
I plan to take advantage of 3 W LEDs 1 and constant-for each color-
Current distribution board.
I will be at the time of instructures when it is done.
I have a lot of other LED-based instructures in my profile to look at my project or focus on future projects. .
