DIY Guitar AMP (LM386)

This is a small and powerful amp that can connect any guitar iPod

I made this this casing out of a Toyota motor oil can

Step 1: Parts That You Gonna Need

LM386

10uf -3

220uf

10k Potentiometer

1nf

47nf

10ohm

1k

4ohm speaker

1/4 inch aux base

1/4 inch to 3.5 mm audio converter

piece of perf board

Step 2: Schematics

Step 3: Things That in This Guitar AMP

Step 4: DEMO

this is just a idea you can make awesome covers like i do here be creative and do more recycling and save earth

hope you all enjoy my intractable if you have any question feel free to comment thank you !

hi i'm thomas rohan. and im 11 how old are you?

[jongscx]

Should go well with these...

$350 for basically a CBG ? nice job if you can get it

[neranjan.ghost]

Thanks for the idea @gravityisweak

What is the sound quality?

[redisni]

Some will say the sound is kinda...

(⌐□_□) ...tinny.

YYYYEEEEEEEEEEEEAAAAAAAAAAAAAAAAHHHHHHHHHHHHHH!

can the value of components in circuit may vary..?

[scristian]

that schematic has a few extra parts than the 200 gain suggested on the datasheet (http://www.ti.com/lit/ds/symlink/lm386.pdf) may i ask what it adds?

Tiene que sonar un poco a lata no? jeje

Your device seems to have a pilot lamp on it, and a power switch, that your schematic omits. You are also missing the 1K2 resistor on pin 1 for the standard 50 gain circuit too. Although looking at a group of schematics on the net I see lots of people seem to leave that part out. C2 should be a non-polar device.

i didn't add the pilot light on schematics and i didn't use non-polar

cap for C2 but it works fine thanks for telling me about the pin 1 problem appreciate your help my friend

*polar

I was under the impression non-porous caps were better with high frequencies.

I did not say it is a problem. As many schematics omit the part. The reference schematic has it though. I did not build the circuit with, and without it, in order to see what the difference was myself. Though I have built it with it, and I know it works OK then.

You can see it here

I happened to use an LM386 to boost the power output of something I was noodling around with in this instance.

tnx mate

I like the concept here, but for many instructables users a schematic with a parts list will not be enough for them to reproduce this build. It is likely that if someone can reproduce a working amp from these schematics alone they are probably familiar enough with electronics that they have already built circuits like this. I think step by step photos would be helpful, as well as some photos of the construction process and go a long way towards increasing the quality of the instructable. Thanks for sharing this.
