Here is the
basic circuit diagram I use. Turn the
chip around so the indent is on the right then the +ve is
at the top and -ve is at the bottom.
This makes sketching circuits easy.
Note the 3 volt supply which is
strongly recommended to prevent it from being damaged or overloaded. At 3 volts all pins current limit.

A good way to go for trying ideas out and
learning about what the PICAXE-08
can do.
After a year I am still learning new tricks this amazing little PIC has
up it's
sleeve.
A simple method of prototyping, making, simple
circuits or just having fun. Make a
toy, data logger
or serious industrial control project. Simple 5 x three terminal interface with
all types of I/O; Digital,
Analogue IR, I2C, Serial Data, Relay, Servo, DC Motor, LDR, Thermistor... A range of ready made
interface modules are also available.
Patch board was developed to be a useful solution for the
experimenter or developer. One off
projects and can be made quickly with just a screwdriver and a PC.
Each chip I/O pin and input output circuit can be configured by simply plugging
in components without
soldering. RS 232 compatible I/O and
analogue in/out.

Vero is a good cheap option if you only have a
few hand tools, have the time and can solder.
It is not the easiest way to go as you have to
be able to fault find. I have used
Eagle Lite CAD
freeware board editor to sort out designs for a
neat finish.
I have taken one of the small Vero circuit
boards as above and mounted it onto a block
of wood or laminate using nails as connection points for each "Pin" of the
PICAXE-08.
Make up a selection of colour coded jumper
leads by cutting bunches of jumper leads
In half and mounting components using sleeving
and hot melt glue. A fast and reliable system.
Here is an ideas used by one Taranaki school,
surface mount components onto some copper
laminate that has been cross hatched with a hack saw. Surface mount soldering can make it easy
for for students and beginners.
A PICAXE module is now available for the
popular electroflash system used in many schools.
This module can be used and experimented with
on it's own or with just a few components to
teach programming and simple PIC techniques.
Simple locomotion and movement can be achieved
with one transistor and direct driving a motor shaft
onto a smooth surface. Rubber sleeving
or hot glue re-treads can be added for speed and traction.
