  • Welcome to the DIY Speaker- Manual

    This is a step-by-step guide to making your own electronic Speaker. The equipment you should have at your station are wire cutters, soldering iron, solder sucker and Bluetak.

    This DIY kit comes with a custom designed amplifier called the Uber Amp 9000 and all of the components you need to make your own set of speakers out of any material. This is a great way to learn how to solder, understand how sound works and make something useful for your listening experience.

    Getting Started

    Top Tips

    Keep an eye out for the top tips. They are highlighted in a yellow box like this!

    Useful Appendix Further information on all the components in this kit can be found in the Appendix at the back of the manual. Learn about their use within the circuit you are building.

    Making Time The kit takes about 2 fun filled hours to complete - depending on how creative you get with the construction of your speakers.

    Stay Safe Keep safe when making this kit! Wear protective eye wear when soldering and clipping component legs.

    How to solder

    Turn the PCB around. Place the soldering iron tip at the point on the PCB where the leg of the component meets the solder pad. Heat for about 3-4 seconds.

    Place the component into the PCB (Printed Circuit Board), make sure it goes in the correct way and it is sitting right against the board. Bend the legs to keep the component in position.

    Step 1

    Step 2

  • 5DIY Speaker - Manual

    Using your other hand, add solder to the heated pad. Add enough solder to cover the pad and the base of the components leg. Remove the solder and leave the iron for another second.

    After soldering both legs, take your side cutters and remove the excess component leg. If you make a mistake, re-heat the join and use a solder sucker to remove the molten solder.

    Step 1

    Diodes

    Take your two diodes which you can see pictured on the right.

    We are going to place the diodes into the PCB (Printed Circuit Board) ready for soldering. To make this easier we are going the bend both of the legs of the diodes at 90 degrees.

    Top Tip

    Use a flat hard surface like your desk or table to bend the legs against. This will give you a nice crisp corner.

  • 9DIY Speaker - ManualStep 1

    Your diode should now be in a U shape look something like this.

    Youll notice that your diode has a black band around one end of the component. This is to show that the component has a polarity and has to go into your PCB a certain way around for it to work. Place your diodes into your PCB where they are marked with a small arrow with a line going through it and a black band. Simply match the black band on the diode with the black band illustrated on the board.

  • DIY Speaker - Manual10 Step 1

    Once both of your diodes are on your board they should look like this.

    Next turn your board over and bend the legs of the components out a little to keep them from falling out. Then push the component gently into some bluetak to keep it secure create a stable base for you to solder on to .

    Top Tip

    Make sure the diodes are in the right way around! Double check that the black bands on your PCB match the ones on the diodes or your circuit wont work.

    Top Tip

    Remember a good solder joint looks like a small hill not an apple!

    Step 1

    Your ready to solder the diodes. Use the same technique as the how to solder steps at the start of this guide for reference.

    Finally snip the excess leg of the component whilst holding it. This stops it from flying off as you do so. You should snip just above the top of the hill of solder you have just created.

    Step 2

    Resistors

    Take your 4.7 ohm resistor. Which will be marked with coloured bands around the component. Your 4.7 ohm resistor bands will be yellow, violet, gold and gold.

    Now bend the legs of the component into a U shape as we did earlier.

  • 13DIY Speaker - Manual

    Top Tip

    Resistors can be plugged in any way around. Their legs are the same length - which is a way to tell that it has no polarity.

    Step 2

    Place your resistor into the position on the PCB marked 4R7.

    Now solder and snip the component legs just as we did before.

  • DIY Speaker - Manual14 Step 2

    Now bend the resistors legs and place them into the board where their position is marked with a 1R symbol.

    The next resistors you need are your 1 ohm resistors. Which will be marked with the following bands; brown, black, gold, gold.

    Finally solder and snip the excess leg of the component.

    Next take your 1.2K ohm resistors which will be marked with brown, red, red and gold bands.

    Bend the legs of the two resistors into a U shape and place them on to your PCB. Where there positions are marked with 1K2.

    2Resistors

    Top Tip

    Read the bands carefully as there are two very similar looking resistors in this kit!

  • 17DIY Speaker - Manual

    Flip over your board, solder and snip.

    Step 2

    Bend the legs of the component. This resistor goes into your PCB where it is marked with 220R.

    Take your last resistor which is a 220 ohm resistor. Which will be marked with red, red, brown and gold bands.

    Step 2

    2Resistors

  • 19DIY Speaker - Manual

    Circuit check! Your PCB should now look like the one pictured on the right.

    Solder and snip your last resistor.

    Capacitors

    Place the two capacitors into your board where they are marked with 100nF.

    Find your two non-polarized capacitors which are pictured on the right. Youll notice that they are very symmetrical with no real distinguishing features. This is often a very good way to tell that the component has no polarity and can be placed into the PCB either way round.

    Your board should now look like this.

    Now solder the capacitors into place. The legs are quite short but will still re-quire a little trimming.

    Step 3

  • DIY Speaker - Manual22 Step 4

    You will see that these capacitors have one leg longer than the other and have a white band above one leg. This asymmetry tells us that the component is polarised and has to go into the circuit a certain way around. The longer leg is always positive and these capacitors mark the negative side with the white stripe.

    There are three sizes of electrolytic capacitors in your kit which all look similar but are slightly different sizes. We are going to start with the 100uF capacitors which physically, are the shortest of the three and have 100uF written down their sides.

    Push the capacitor flush against the board. Turn over and then solder and snip the components.

    Place your two 100uF capacitors into your PCB. Making sure that the long leg matches the + symbol on your PCB and that the white stripe matches with the - symbol.

    Step 4

    Technology Will Save Us

  • DIY Speaker - Manual24

    Place the capacitors on to your PCB where the two capacitors positions are marked 2.2uF and 22uF respectively. Double check they are in the correct positions!

    Next are your 2.2uF and 22uF capacitors. Careful as both are the same size but have different values. Look at the sides of your capacitors. One should have 2.2 written down the side and the other 22.

    Top Tip

    Make sure you put the capacitors into the board the correct way around. Long leg is positive (+) and white stripped
