MiniReg 1.3-22V Adjustable Regulator - This compact regulator PCB can be used to produce a fully regulated DC supply ranging from 1.3V to 22V at currents up to 1A.  Depending on how much current you need, it can fit into tiny spaces and is easily connected with 2-pin headers for DC input, DC output, an on/off switch and a LED.__ SiliconChip

MkI Video Digitizer - This frame grabber design digitises pictures to very high quality in monochrome  (8-bit black & white) . Although designed for the European standard 625-line / 50Hz TV system, it should work with the American 525-line / 60Hz standard with minimal modification. __ Designed by W.A. Steer  PhD

MkII Video Digitizer - A "video-digitiser"  (also known as a "frame grabber") captures television pictures from a TV set, camera, or video recorder, etc., and forwards them to a computer for display, storage, or general manipulation. This document describes a home-built digitiser which interfaces to an EPP  (or bi-directional) parallel port on IBM PCs. __ Designed by W.A. Steer  PhD

MMC to PIC16F876 - Schematic Only

MNA, Low Profile, Low Cost, Fully Integrated Monolithic Microwave Amplifiers - AN-60-016  Application Note __ MiniCircuits.com

Models make the difference in high-speed PC-Board Design - 04/15/99 EDN-Design Ideas - You're ready to start a high-speed pc-board design.  You can build the board, basing the design on component specifications and your own design expertise, and hope it works.  Alternatively, you can simulate the design before assembling a prototype and, if you do it correctly __ Circuit Design by Jim Lipman

More Fun with the PICAXE: a Shop Door Minder - Part 2 of the series shows you how to build a "Shop Door Minder...With Attitude".__ SiliconChip

More Fun with the PICAXE-Part 3: Heartbeat Simulator - Nine components are all you need to build this simple circuit.  The effect is so realistic , it almost seems alive!__ SiliconChip

More Fun with the PICAXE-Part 4: Motor Controller - A Few changes to PICAXE's output circuit and some new code are all thats required to build an effective motor controller.__ SiliconChip

More Fun with the PICAXE-Part 5: a Chookhouse Door Controller. - Make an Electronic Chookhouse Door Contol using our PICAXE Project.__ SiliconChip

Morse Clock-Look Mum, No Hands! - If you want to know the time, you've got to learn Morse code.__ SiliconChip

Motorola 68HC11 Evaluation Board - Build a low-cost evaluation board for Motorola 68HC11.  Downloadable BUFFALO V3.4 to 32kB SRAM for learning __ Designed by Wichit Sirichote

Moving Message Display - It's easy to build, easy to program, easy on the pocket and easy on the eye.__ SiliconChip

Moving-Dot Display Interface Uses Three I/O Lines - 05/01/08  EDN-Design Ideas - A moving-dot LED-display interface to a microcontroller uses only three output pins __ Circuit Design by Abel Raynus, Armatron International, Malden, MA


MP3 IDE interface - This is a work in progress  I'm building a hard-drive based MP3 player using the MAS3507D MP3 decoder, and a PIC 16C64.  I've started keeping a vague log of my activities, in case anyone's interested.   __ Designed by Ben  last name not found

MP3 Player with SD Memory Card - The MP3stick is a simple and small portable MP3 player.  A microcontroller Atmel AVR ATmega128 is the heart of the circuit.  MP3 decoding is done by an VLSI VS1011b decoder IC.  A MMC/SD card works as memory medium for MP3 files, playlist files and skin files.  The player is designed to draw his power from a LiIo/LiPo battery with 3.6V.  a charger circuit, based on MAX1811, is included.  All information will be shown on a Nokia color LCD with 128x128 pixel and 256 colors.  

MTK-85 8085 Microprocessor Training Kit - Single board computer built with a 1970 Microprocessor, the Intel 8085.  Best for learning the fundamental of computer system.   __ Designed by Wichit Sirichote

Multi Chip Programmer - You will need NotePad2.exe or NotePad2.zip so you can take a .asm file from one of
the projects we have produced and use it to write your own program.  __ Designed by Collin Mitchell

Multi NiCad Charger - This unit was constructed in the shell of a Radio Shack battery charger.  The original unit charged only one type of battery at a time and only in pairs.  This unit allows for mix and match for AAA, AA, C, and D cells.  Each battery is individually monitored and charged.  An LED for each one flashes to show the current charging condition as follows __ Designed by Luhan Monat - Mesa Arizona

Multi purpose IO board AVR Atmel Mega - DMX PPM analog sample and interfacing RS232 RS422 RS485 __ Designed by Thomas Scherrer OZ2CPU

Multi-Function GPS Car Computer, Pt2 - Last month, we introduced our new GPS Car Computer and provided full constructional details.  But there's a lot more that we haven't covered yet __ SiliconChip

Multiple Switches with Single PIC Input - There are many techniques to implement multiple switches into PIC microcontroller.  This technique requires only one ADC pin to detect voltage level when each switch for each state is pressed and each switch is associated with a voltage.  For example : If we need to connect 16 switches with 10 bit PIC.  

Multi-Purpose Car Scrolling Display - AM Broadcast Band Portable Loop Antenna__ SiliconChip

Multi-Purpose Car Scrolling Display, Pt.3 - In Pt.3 this month, we describe how the Multi-Purpose Car Scrolling Display is connected to the car and used.  It's driven using a simple command-line program.__ SiliconChip

Multi-Throttle Control for PC Flight Sims - Are you into PC flight simulators? Find the control your typical controllers give you just a bit less than satisfying? Take a step up: add this very simple multi-throttle controller and start flying with the big boys ...__ SiliconChip

My PIC Programmer - An easy-to-build PIC programmer, based in the JDM.  Uses the serial port.   __ Designed by Jose Pino
