Introduction: Altoids IPod Speaker
Also can you guys please leave any comments to help improve my process!
Okay so after looking around this site for a few days I was able to compile
almost my version of Portable speakers. It was my first official attempt at a electronic
project and I am glad at how it turned out.
Okay so i used this instructable https://www.instructables.com/id/Rechargable-pocket-sized-amplifier/ by Brunoip
I minimize his circuitry by getting rid of the switch and adapting to become a rechargeable
amplifier i did this just for simplicity as i was not planning on using it a lot.
I just used a Altoids case as the enclosure. I also glue gunned a piece of paper to the bottom of the
circuit to prevent any shorts. Note that the Circuit says 3volts, i realize that for better sound
quality you had to up it to 9volts.
The Parts of the Circuit is
R1: 4k7 resisor ( yellow violet red)
R2: 1M resistor (brown black green)
Q1: BC548 or 2N3904
Q2: BC327 or 2N3906
C1: 10uF capacitor
9volt battery and connector
jack-in part of a pair of head phones.
The Quick Steps of the process for those that are interested.
First trace out the cirucit design/layout onto a pcb.
Second start to solder on the smallest object first like the two resistors.
Third solder on the capacitor and the transistors.
Fourth where it says "in" on the circuit you solder in the jack to be connected to the musical device.
Finally you connect the power source of 3v-9volts and the 8ohm speaker of a reasonable size.
Tip use a jumper wire to connect the points on the circuit it says solder.
We have a be nice policy.
Please be positive and constructive.
