Dari sekian banyak rangkain pcb power amplifier yang di jual di pasaran,mulai dari jenis,merek,atau pun bentuk.Ada power amplifier OCL dan power amplifier BTL ada power amplifier stereo dan ada juga power amplifier mono.Untuk semua jenis power amplifier di atas kwalitas Hasilnyaseperti ini: Berikutnya solder satu persatu kaki komponen agar menempel ke PCB. Gunakan timah seperlunya, jangan terlalu banyak (banjir), secukupnya saja. Jangan terlalu lama meletakan solder di kaki komponen, beberapa komponen yg rentan panas (seperti elko dan IC) bisa terbakar jika terlalu lama disolder. untukmenambahkan lampu ya gak masalah, untuk mendapatkan hasil yang maksimal. pakai supply 12 volt atau pakai supply dari tone control. kemudian rangkai lampu secara seri paralel. dengan masing masing 3 lampu di rangkai seri kemudian selebihnya di paralel.

Introduction How to Make Led's Pulse on BassIn this tutorial i am going to show you how to easily make a cool light setup that would be music are going to build a small circuit in order to drive those led's. The way i deed it was using an atx power supply witch some time ago i converted into a lab power supply in witch i integrated the led controller but you can make a small case for it as of all i need to that opening the power supply case it's dangerous!!! Remember to disconnect it from the wall plug and even after that let it sit for a couple of minutes because the internal capacitors can store a dangerous charge even after that. The circuit we are going to make is going to work even at low volume because i' ve seen others doing it with a simple transistor but the volume has to be at almost the highest volume in order to work and we are also going to put a small low pass RC filter in order for the led' s to flash only on the bass because otherwise the will stay pretty much on all the time. Too much talking, let's actually build something!Step 1 Required PartsNeeded parts1 x pc power supply 1 x lm741 or lm324 or equivalent operational amplifier1 x prototyping board 1 x switch1 x Tip31 or equivalent transistor 1 x uF at 25 V or so electrolytic capacitor3 x 1 kohm resistors1 x 10 kohm resistorsome copper wirespeaker connector1 x mm female audio jackCables- mm audio splitter - a cable with mm audio jack a both end's the type of cables you need depends if you connect it along side the aux or from the amplifier' s out line which usually is an RCA connector so you will need an RCA to jack cableTools - soldering iron - screwdriver' s- patience Step 2 Now Let's F**king Build It!!!First off all we need power, so we are going to get it. You don't actually need to open the power supply, you can use the wires that are attached to it already an cut the ones you don't need. If you read my other instructable regarding the lab power supply you'l find out that the green wire need's to be connected to a black wire ground in order for the power supply to start. You will need three more wires which are +12 rail yellow ground black and -12 rail blue so make sure to leave them intact in case you cut the rest. Look at the circuit diagram and understand it. The circuit composes of three main blocks filtering stage, amplifying stage and led's driving stage. The low pass filter is made using a 1 kohm resistor and a 1 uF capacitor and it's role is to let only the lower frequencies the bass to be amplified. The filtered audio signal then goes into the non-inverting input of the op-amp ic, the inverting input is connected between two resistor, 1 kohm resistor connected to ground and 1 10 kohm resistor connected between output and inverting input; those set the gain, in our case the signal will be amplified 11 times. Gain formula is this gain=1+R2/R1. Last stage is just a transistor which drives the led's. You connect the op-amp output to the base of the transistor using a 1 kohm resistor the transistor must be capable to handle the current passing through the led's so it is a good idea to first measure the current with led's on and refer to transistor' s datasheet to find the collector maximum current "Ic", if the current is higher than that you should mount a small heat-sink on the transistor or get one with much higher current rating. And finally the led's "+" pin is connected on the +12v rail if you have 12v led strip like i have and the "-" pin is connected to the collector of transistor which will open the path to ground, emitter being connected to ground. The way I did it was using a speaker connector like one in the pictures above, so I can easily connect and disconnect the led' s or ad multiple strip's of led' you can start putting everything together and solder all done soldering take a multimeeter and check connectivity, small tip if using lm741 power it from +12v to -12v or it won't work because it needs at least 18 V to function. Newer ones like lm324 might work even at 12 V but it is best to power it at a higher voltage to get best 3 Testing Connect all the cables and test the beast. Introduction Bass Lights This project will light up as many LEDs as you want in sync with the bass of every song. This is an Extremly easy project to make, even without electrical experienceStep 1 MaterialsYou will need a subwoofer that you can take apart, some wire, as many LEDs as you wish to use, as many clear pen tubes as LEDs, water, and whatever material you want to make a stand out ofStep 2 ToolsTools you will need are wire strippers, wire cutters, needle nose pliers, soldering ironStep 3 SubwooferTake the subwoofer apart or on some just unscrew the subwoofer speaker. The only thing you need to focus on is the red and black wire attached to the speaker. Strip half an inch off of the end of 2 of your wires. You should mark which wire is negativeblack with a felt pen along the length of the wire. Now solder the unmarked wire onto the positive red wire. Next, solder the marked wire onto the negative black wire. Before you put the case back together, use your wire cutters to make a small nick in the case so that you can fit your wires through so that the case doesn't damage the wires Put the case together. Step 4 HolderYou can use anything you want to build the holder. I used Lego because its cheap and super easy to work with. The holder should be able to fit your clear pen in it lengthwise. And hold the pen straight as there is going to be water in it. Once your enclosure is complete, fill your pen tubes with water and place them in the holder Note I taped my pens to make the LEDs brighter. In some cases it may not be neccassary, it depends on the LEDs used Step 5 LEDs and WiringThe wiring is really simple. I have included a diagram but all you need to do is connect all the positive ends of the LEDs together and all the negative ends of the LEDs together. The negative side of the LED will be flattened or have a shorter leg, depends on the LED. Connect all the needed LEDs and wires together with solder and a soldering iron. Next connected the marked wire from the subwoofer to the negative of your LEDs. Connect the unmarked wire to the positive of your LEDs. If your structure has a lid, put the lid on, as you are finished!!Step 6 Turn It Up!!Just connect your subwoofer and speakers and watch the light show!! Thank you for having a look at my first instructable.
