Make noise with a PIC - 7-Aug-03 Issue of EDN Building a stable noise
generator for audio-frequency purposes requires only a few components. The circuit in
Figure 1 relies on linear-feedback shift registers and some simple software. An
eight-pin Microchip (www.microchip.com] PIC12C508 controller (IC2] with a short
program generates pseudorandom noise at its output pin, GP0....[Design Idea by Peter

Make Your Own Single-Side PCB for Easy-Downloader V1.1 - I am very happy
with my student, Plermjai(his name means feel delighted too) Inchuay (his family name
means angel helps him), who provides me his page describing how-to-make a single side
PCB for the Easy V.1.1. So cool! his prototype was made by hand writing with a pen for
making PCB! Available now single side with Protel format. ….(design added 06/09)

Marshmallow Gun - This device uses a PIC12F629 to create a burst of 30 high
voltage pulses. The PIC activates a 1000 volt N-Chan FET driving a standard
ignition coil. After the ignition, the PIC goes dormant until activated again.
Most of the electronics, including ….) [Luhan Monat - Mesa Arizona] |

Matrix Display using PIC 16F628 - Config: WDT Off, TIMER On, OSC Internal
RC, MCRL Off, LVP Off The Display is an array of 5x24 Leds. I used Shift registers to
light up every column, DO NOT USE ANY 74LSXXX TTL. The 74LS is a Low Power TTL that
doesn't light up the leds very well. Use the 74HCXXX series or 74FXX series. After
almost 2 weeks sleeping only 5 hours every night, the circuit is working. Is hard to
get a picture while the display is scrolling the message. This LED Display
allows up to 128 Characters, Just write your message in the EEPROM Data and it will be
displayed. If the Display is "blinking",.... |

Max-038 Signal - The Max-80 function gernerator IC is specified to work to
20 MHz. So far, this unit works nicely to 50KHz. Since I seldom need signals higher
than that, it has taken up a happy ….(electronic schematic added 08/08)) [Luhan Monat
