Cigar Box Guitar Amplifier

I have been an electronics hobbiest for several years, and there is something special about making musical toys. I also run a website, tech-tut. I'm finally attempting a highly detailed process that I can't exactly publish on my site, so here I am on Instructables. This is my first Instructable ever, and I value any feedback to make it the best it can be. Building a Cigar Box Guitar Amp is not difficult, but it can be time consuming, especially if you want it to be near-perfect.

Some things that don't always work out for me are the hole diameters and the occasional scratch in the soft wood of the cigar boxes. Even some of the nicer, tougher cigar boxes give way easily if your fingernail slides across the grains.

The time frame to complete a Cigar Box Amp ranges from a little over an hour to four hours depending on whether you have an assembly line or not. It also depends on the cigar box. If you have a thin box, it won't take you as long. Thick wooden boxes take longer to file the holes unless you have potentiometers and jacks with long threads.

Overall, you will enjoy your Cigar Box Amp. Whether you buy one pre-assembled or built it from scratch in your favorite cigar box, you can expect that people will be impressed. This is the toughest part. You need to decide what you want to install your amplifier in. The easy choice for me is to use a cigar box, but Make magazine ran an article that used cracker boxes. Next, you need to go shopping for parts. There are kits that you can buy with nice printed circuit boards out there.

I've never used one because I like the "from scratch" method. These are the parts from my latest Jameco. You still have to find a cigar box and pay for shipping. Half the fun is shopping around for parts. Your Cigar Box Guitar Amp is about to be born.

I'm going to describe my method using an imaginary 7"L x 7"H x 2. These dimensions won't exactly match the photos. Every cigar box is different , and the measurements that I make will not be the same. Do a dry layout! Make sire that the parts will fit the cigar box. You also want to make sure that the controls and parts do not interfere with the closing of the cigar box. I always start with the speaker location and work my way from there.

I like to have the speaker at the "bottom" of the amp like most traditional, store bought amps. We are using a 4" speaker, so the center of the speaker is 2" from any edge.

We will mount the speaker with the center 2. The thickness of the wood on my imaginary box is. Then find the center of your box. The center of my imaginary cigar box is 3. If the bottom left of the cigar box is the origin of an xy plane, the xy coordinates for this hole would be 3. Use a punch or the tip of your pencil to bore a small divot so that your drill doesn't travel. Using a hole saw, drill a hole here. The next holes to drill are for the LED, potentiometers, input jack, and voltage jack.

In the drawing I have everything but the voltage jack on the "front" of the cigar box. I usually call the actual bottom of the cigar box the front.

I evenly space them across the top edge of the front. Each hole is 1. The outside holes are 1. These holes are 1 - 1. You can be creative and put your parts wherever you'd like. The final part to be drilled for is the power jack. You can put it on the side. Simply center it and drill wherever you please. Again, every cigar box is different, and giving you an exact measurement probably wouldn't work. For my imaginary cigar box, I will drill a hole that is at 3.

Drill each hole so that the parts fit using various drill bits. I use a stepper bit and then file the hole with a round file to get the final diameter. Dry fit all of these parts before continuing. Once the parts fit into their holes, sand the speaker hole so that it looks nice.

Start heating up your glue gun! Note: Be careful not to sand the outside of the cigar box. You only want to knock off the burrs left from the drilling process. Dry fit all of the parts one more time before continuing. Visually inspect the box to make sure that the lid will close. If everything acts like it's going to fit, then set everything aside except for the box and the speaker.

If you choose to use a speaker cloth, now is the time to attach it. Spray a layer of glue inside the enclosure around the speaker hole. Cut a circle of cloth, and place it over the hole on the inside of the box. Stretch it out so that it dries tight. Next, put some hot glue on the corners of the speaker frame on the speaker cone side [Be sure not to get any glue on the speaker! Once it cools for a few seconds, apply more glue to the corners to get a good bond to the box.

Once this glue cools, your speaker should not move. Next, insert your potentiometers and tighten the nuts. Use a rotary cutoff tool to trim the ohm trim pot shaft. It is too long. Insert your input jack and the voltage jack, and tighten the nuts. Finally, press in the LED holder.

Now, you are ready to make the circuit. First, you'll need the schematic and layout. Then populate and solder the parts around it in accordance with the schematic and the wiring diagrams. My drawing below shows you pretty much what connects to where. Looking at both will provide some insight into the wiring of these circuits.

I also drew a picture to give one more view to the wiring diagram and layout. The drawing below is exactly how I install my circuits. If you want a printed circuit board, GeneralGuitarGadgets. That's a little steep for me since I can populate and solder a circuit onto perfboard in under ten minutes. It's the wire connecting that will take a little longer. After you solder the circuit board together you can make the individual connections to the controls.

Following the various wiring diagrams that I've linked to should make it fairly easy. After publishing I realized that figuring out the wiring is still tricky! The next set of instructions is going to be full of step by step photos. The colors that you use to make this circuit don't really matter, but I am going to describe the colors to help make following this process a little easier. Picture 1: The first step is to solder the negative battery wire A and a long black wire B to the tip terminal of the voltage jack.

Picture 2: Solder the positive battery wire C to the contact terminal of the voltage jack. Picture 3: Solder a long red wire D to the sleeve terminal of the voltage jack. Picture 4: Solder the long black wire B from picture 2 to the sleeve contact terminal. Picture 5: Solder a 1k resistor to the LED's cathode. This is the end with the small indentation. Picture 6: Solder a long black wire E to the other side of the 1k resistor.

Picture 7: Trim the long black wire E from picture 6 to the third terminal of the ohm pot. Then solder two long black wires F and G to the same contact. Take notice of the pot's orientation.

Many electronic projects require the use of a small audio amplifier. Be it a radio transceiver, a digital voice recorder, or an intercom, they all call for an audio amp that is small, cheap, and has enough power to provide adequate loudness to fill a room, without pretending to serve a disco! About one Watt RMS seems to be a convenient size, and this is also about the highest power that a simple amplifier fed from 12V can put into an 8 Ohm speaker. A very low saturation amplifier may go as high up as 2 Watt, but any higher power requires the use of a higher voltage power supply, lower speaker impedance, a bridge circuit, or a combination of those.
