| Introduction to Breadboard (Protoboards), Part 2 of 2 |
 |
This video continues part 1 by showing how a
breadboard, also called a protoboard, is used to
build electronic circuits without soldering, by
guiding the student through 10 steps to build a
blinking LED circuit based on the 555 IC timer
chip. The circuit also needs 3 resistors, 1k,
4.7k, and 10k. It also requires a 10 uF
electrolytic capacitor, an LED, some jumper wires,
and a 6-volt battery or power supply. Tags : breadboard protoboard electronic prototyping 555 |

| The Breadboard Band, 2005- |
 |
The Breadboard Band is a performing band that uses
breadboards made of freely constructed electronic
circuits to play music. We produce audio and
visual expression through the most minimal,
fundamental elements in the form of showing the
electronic components of an instrument while
directly touching and forming the electronic
circuit by hand. The electric signals released
from hand-made electronic circuits releases
extremely rough and ferocious wave patterns. This
performance is based on improvisational interplay,
and we pull powerful music into shape through each
member's operation, while discovering new sounds
by hand. Tags : Music Performance Live Improvisation Electronic Circuit Breadboard Japanese Noise Media Art Audio Sound Chip PSoC Wire |

555 sqare wave synth on my tiny breadboard. I
improvised a "keyboard" to it and it have a "fine"
tune knob too. After the video i just grab out all
the parts from the board :D

| USB AudioStreamer on breadboard |
 |
First attempt to make a USB Audio 1.0 soundcard
with a Microchip PIC18F2550.
The scheme is basically the one found on
http://www.raccoonrezcats.com/soundcard.html made
by Mike Zoran, with some personal changes (nothing
important anyway).
I have used trimmers instead of digital
potentiometers because I'm waiting for their
deliver. Despite this, the volume can still be
adjusted on the Windows control panel by moving
the Wave slider.
The soundcard works ok, has a low latency but the
use of a 12-bits DAC and rail-to-rail 0-5V op-amps
degrades the sound a lot. Without any data
streamed, the USB power supply has a bad ripple (I
can hear other devices sending messages), and the
breadboard can only make it work worse. An
external power supply with appropriate power
filtering, the use of better (audio specific)
op-amps, hi-end DACs and an accurate PCB design
would make it sound waaay better.
As Mike wrote, his project was released ONLY as a
cheap learning tool. An EXCELLENT learning tool
