The secret to minimalist design
is to reduce the parts to what MUST be there
to get the task done.
But before that you reduce the task itself...

Software
BTc PICsound
One-bit sound recording/playback on a PIC
One of my best works, this is PC software that displays a 8-bit mono sound
file (.WAV file) and ENCODES it into a 1-bit bitstream! The bitstream can
be played back very simply on any PIC or other micro with one digital
output pin and one resistor and capacitor (RC network). Now updated to v3.0
BTc Encoder manages Sound Library files, and can export .BTL format
to be loaded direct into the
TalkBotBrain
cheap sound playback hardware.
SuperFind 2.0 (for Windows)
A super-fast file finder program, SuperFind is a very handy tool to find
any file or quantity of files on your PC instantly.
HexCon 1.0
A programmers helper, HexCon is a small fast tool to convert between
Decimal-Hex-Binary. It can also display PC keyboard codes.
ToMetric 1.0 (for Dos)
A fast and accurate imperial-metric converter for Gerber files, ToMetric
is suitable for CAD and PCB Gerber files.
EE-Draw 1.0 for Dos
EEDraw is software that lets you draw circuit diagrams, flowcharts etc
with the mouse, but the picture is actually made of
TEXT symbols and can be saved as a normal text file!
This is ideal for adding diagrams inside your text emails and
allows the use of diagrams on mailing lists where attachments are not allowed.
A Binary Clock for Windows!
Here is a working binary clock that runs under Windows and uses my
Black-Standard
for easy-readable binary clocks. I have also provided
my source code for Borland C++ Builder in case you want to make your own
Windows binary clock.
WavMak Waveform Maker

and creates a wave file of any specialised waveform shape.
Useful for audio testing.

Zero-error 1 second timer algorithm for PIC.
Based on Bresenham's algorithm, my implementation will generate a 1 second
(or other) timer period from ANY frequency crystal or ANY
frequency interrupt. An obvious use is to add a one-second clock pulse to
an existing design that has an "imperfect" crystal like 4MHz etc.
PIC source code supplied. NEW 21st Nov 2009 - Added ZEZJ This is a
Zero Error Zero Jitter algorithm, it produces an exact xtal-locked period
from any xtal and any period value, just change the one easy PERIOD constant.
NEW 21st Feb 2011 - Added DTMF sine generating example
14th April 2013.

"The Black DTMF decoding algorithm"
A couple of systems I developed for decoding DTMF "touchtone" codes on
a very small cheap PIC. The systems use a combination of period measuring
and spectrum analysis and pattern recognition decoding. It sounds complex
but ended up being quite simple and fast.
27th Apr 2011.

generate a "heading" from an XY move of a robot or CNC machine, or to
generate a tilt angle in degrees from an XY accelerometer.
PIC-thread, multi-thread "parallel" processing using PICs.
I create some simple systems to do multi-thread type projects (a form of
parallel processing) in firmware just using a normal PIC microcontroller.
There are code examples and some simple PIC "multi-thread" projects.

utilised as a practical clock display.

High-resolution cap meter using PIC 16F628
This is a digital capacitance meter using a 16x2 LCD that gives a number of
advantages over other PIC digital cap meters. It only uses one cheap PIC

lot of digits resolution, handy for variable capacitors and "pico-cap"
projects like capacitive touch buttons etc. This is an easy to build project
with high performance.

sine signal generator. All it needs is a cheap 18pin PIC 18F1320 and
a couple of external parts, and it is a complete high-performance
xtal-locked sinewave generator. A great PIC project for a beginner
and very useful!
20th Jun 2011.
1kHz precision sine generator using PIC
This is a complete open-source project that generates a precise xtal-based

SmartGLCD Review.
I play with the Osram optical tilt sensor!
This tiny device is a modern version of the old mercury tilt switch,
or gravity tilt sensor. But this one uses an internal inrared beam and tiny ball.
Some PIC projects you can do on the BIGPIC6 development board!
1. RS232 timer - shows exact baudrate of a device.
2. RS232 converter - bidirectional baudrate converter with led bargraph.

Bitbang serial data to/from the PC with no hardware needed!
Here is code to send and receive serial data with a PC serial port, using
only 2 resistors and a serial plug. It does not require a PIC with a
USART and can be used on the cheapest and smallest PICs. This also
has a full project using the Sharp GP2 IR distance sensor!
The sensor distance is converted to actual cm and transmitted to PC
serial port every 2 seconds. It uses my own code for converting the
exponential output of the GP2 sensor to linear distance in cm.
Using a mini TrackBall as a controller!
I found a source of very cheap miniature trackballs, so I hacked the trackball
and used it to control X and Y values. First project is a TrackBall
controlled RGB LED, to control colour and brightness.
12 digit LED display using NO PARTS
Driving a 12-digit 7-segment LED "calculator" type display directly from one
PIC using NO resistors and NO other chips. I include PCB design suitable for
toner transfer and PIC source code for a clock, stopwatch, and a serial controlled
12-digit display.
My regulated psu "Gainclone" amp
I built a high performance "Gainclone" hifi amp with full regulated power
supply in a great rugged old 1980's power amp rack case.
The MIDI-Bash project
Some very simple, easy to build MIDI drum controllers using PIC micros.
Hit the pads and they send MIDI messages to any standard MIDI sound module
to make your own electronic drums etc.
Now with photos and full PIC source code!
The MIDI-Bloop project
Some more simple, easy to build MIDI "sound-source" devices using PIC micros.
When MIDI note commands are received, these PIC "synths" play
musical notes.
Partially finished.
Kits to build Black Standard Binary Clocks!
Clocks no longer for sale, but I have provided free source code in PIC assembler
and (new for 16 June 2009) now in C source code too.
Make a OCXO (xtal oven) for $1
Using just one transistor and a cheap NTC thermistor this little circuit
keeps a crystal at a regulated temperature so it can be used to drive a
high accuracy real-time clock.
DC Motor Encoder - measures motor speed
This one-transistor design can provide a simple speed signal from any cheap DC
motor by sensing the commutator ripple as the motor turns.
DC Motor Over-Current Sensor
This cheap reliable one-transistor circuit activates a digital output and LED
when the Motor (or other device) draws current that exceeds the (adjustable) limit.
12-key Keypad to PIC using just 3 pins!
Needs only 7 resistors, 3 caps and some PIC code and allows connection
of a telephone style 12-key keypad to a PIC with only 3 PIC pins needed.
Ideal for making a remote control with the cheapest PICs.
$10 Eprom Eraser - simple 4watt fluoro tube driver
Suitable for any 4 watt (5") fluorescent tube and 240v AC mains, this is a very cheap
and simple way to light up the tube.
Self (power) switch a PIC or other micro
This is a really cheap and SIMPLE way to turn ON a PIC or other micro
with one button push, then the PIC can turn itself OFF when the task is
completed and in the off state the circuit uses NO POWER. Ideal for
battery operated gizmos like remotes etc.
Simple +5v to +13v converter
A simple 2 transistor circuit generates +13.3v from a +5v supply.
Useful for hobby PIC programmers that need +13v for MCLR Vp. May also
be useful to drive old memory chips that need +5v and +12v supplies.
2-Speed clock for PIC or other micro
This idea allows a PIC or other micro to switch between 2 clock speeds
using one of it's digital output pins. The PIC runs at a very low speed
to conserve power and instantly speeds up when needed to perform tasks.
