PIC Toolkit
Mk 2
A revised version of our popular PIC Toolkit (July '98), this all-new
PIC programming tool is a real pleasure to use. It supports PIC16F87x
series as well as the PIC16x84. All-new DOS-based software helps you configure
PICs, program, assemble, translate .hex/ .obj, TASM/ MPASM
PIC Toolkit
Mk 2 is now obsolete and you should use the TK3 (Toolkit Mk3) - October
2001 issue.

AM/
FM Radio Remote Control
No licence needed in the UK for this system which uses pre-tuned RF modules.
Range typically 100 metres in free space. Fully detailed transmitter and
receiver project with four relay outputs. Hand-held transmitter has four
keyswitches (pictured above). Based on the Holtek HT6014 transmitter / HT6034
decoder chipset, this design will find many control uses around the home. |

MIDI Handbells
Our MIDI Hand Bells is a form of MIDI interface that connects to an instrument's
MIDI input, which is set up to produce a desired sound (e.g. bells). A
set of eleven switches can then be used, each held by an individual user.
By operating the switches in the correct sequence, a melody can be created
in much the same way that hand bells are played. PIC microcontroller based
project.
In the August
99 issue (P.575) we said that on P. 327 Fig, 3, the negative lead of the
electrolytic capacitor C2, connected to row K25, is incorrect. It should
of course go to row J25, the 0V track.

Special
Feature: PC Engines from 4004 to Pentium® III
I'll see your PII and raise you two Celerons! This must-read
article documents the development of the Intel microprocessor. Love it or
loathe it, there's no denying its widespread adoption in the desktop and
workstation computer industry, and this authoritative article by an industry
insider lays bare how the microprocessor has evolved from its humble beginnings
as a 23,000 transistor chip to today's 7.5 million monoliths. Also discusses
surrounding technical jargon. If you don't know your DIMMs from your cache
from your Xeons, this article is for you. |

PhizzyB
Computers Part 7
Let's get PhizzyCal, PhizzyCal...... Ahem. Sorry. In the last constructional
article of this highly-regarded series, our PhizzyBot is fitted with the
l.d.r. array, and it will move towards a source of light, correcting its
route as it travels. Demonstrates command and control principles. The
computer tutorial series written exclusively for EPE by "Max"
Maxfield and Alvin Brown of Maxfield &
Montrose Interactive Inc. uses a unique mix of practical build-it-yourself
hardware and CD ROM software to provide the best insight into computer
programming & control methods. Don't miss this great educational series
which is a barrel of laughs and great fun! Remember, back issues are available!
Please note,
the PhizzyB hardware is now almost obsolete, with few kits or MCU chips
remaining. Please check all parts are available before commencing construction.
