PIC Programmer
Alexander Enzmann
Why buy a PIC
programmer when you can customize your own? Alexander
shows you how. His programmer operates on USB power
and doesn’t require any device drivers. p. 12
Keywords: USB, PIC, programmer, flash, PIC18F2455,
Windows, boost converter, PWM, PocketPC

Electronic Gear Control
Add Electronic Gears to a Metal Lathe
John Dammeyer
John upgraded
his metal lathe with a PIC18F2620-based gear control
system. In this article, he explains how to design
and write code for your own electronic gearbox.
p. 36
Keywords: Gearbox, PIC18F2620, lathe, RS-232, threads,
stepper motor, CNC

Low-Cost
Gas Leak Detector
Brian
Millier
A gas leak
in the chemistry lab in which Brian works can mean
big trouble for the electronic instruments he uses
on a daily basis. That’s why he built an ATmega88-based
gas leak detector. The system enables him to monitor
for small leaks around the lab’s expensive equipment.
p. 44
Keywords: Leak detector, gas, ATmega88, helium, hydrogen,
thermal conductivity, Wheatstone bridge, NTC, filament,
DCP05012BP, LM334, TLC2254, AD654, LCD

Mamontov
Ilya turned
an ordinary TV into a digital storage oscilloscope
with a sampling rate of 160 ksps. In this
article, he explains how to use an LPC2138
microcontroller to build a high-resolution
system of your own. p. 52
Keywords: Oscilloscope,
TV, LPC2138, MCB2130, video, PWM, DAC, SSP,

Smart Probing
An R5F2113-Based Soil-Monitoring System
Alain
d'Espaignet
Alain's R5F2113-based
monitoring system measures soil moisture, temperature,
and light levels for potted plants. An audible alarm
sounds when any measurement exceeds or falls below
the preset limits. The principles he describes can
be used in a variety of designs. p. 58
Keywords: Plants, temperature, moisture, light,vibration,
probe, light dependent resistor, thermistor, gypsum,
sound

Smart Character Display
MCU-Based Information Messaging Made Simple
Jeff Bachiochi
Back in 1990, Jeff built a simple microcontroller-based
LED moving message display. Today you can build
a “smarter” PIC16F737-based system for a lot less
money. p. 72
Keywords: Ethernet,
ENC28J60, DMA, stack, PIC18F97J60
