3 Input Supply Powers 3.3 Volt Portables-  The single-ended primary-inductance converter (SEPIC) of Figure 1 accepts input voltages ranging from 3V to over 6V, and produces a regulated 3.3 V, 200mA output.  It accepts an input voltage from three sources: a 5V dc wall cube, a 3-cell AA battery, and a lithium backup battery.  App Note 136 __ Designed by Len Sherman, Maxim Integrated Products, Sunnyvale, CA

3-Input Supply Powers 3.3V Portable-  04/13/95 EDN Design Ideas:  The single-ended primary-inductance converter in Fig 1 accepts input voltages ranging from 3 to more than 6V and produces a regulated 3.3 V, 200-mA output.  The converter accepts an input voltage from three sources a 5V dc wall cu __ Circuit Design by Len Sherman, Maxim Integrated Products, Sunnyvale, CA

Aladin interface-  Whoever thinks about reproducing an interface for the Aladin, should first of all be aware of the fact that there are two different versions of the interface.  The first version, easier to assemble, enables the user to transfer dive data from the Aladin to the personal computer.  The other version, a more complex construction than the first one, enables the user both to transfer data from the Aladin to the PC and to configure some Aladin features via the PC. __ Designed by Matthias

Controlling your SLR Camera from an Ipod-  How to control your camera shutter release from your Ipod (r) or other MP3 player. __ Designed by © 2014 - 2003 Paulo Oliveira'

DIY Microphone Cable for iPod Touch (2nd Gen)-  Put together your own Y Splitter Adapter Mic/Speaker recording cable as shown in the circuit diagram below to use a PC Mic Headset with the iPod Touch (2nd Generation only) and iPhone. __

Dual Current-Limiting Switch for USB Applications-  App Note 32 --Dual Current-Limiting Switch for USB Applications __ Designed by Micrel

Interfacing ADXL202 Accelerometer to Palmpilot-  EE-248 Analog Devices App Note__

iPod / USB MP3 charger using MC34063 switchmode regulator-  Schematic Only__

MIC2527 Voltage Drop, Packaging & PCB Layout-  App Note 30 -- MIC2527 Voltage Drop, Packaging, and PCB Layout __ Designed by Micrel

Palm-Top/Hand-Held to RS-232 Serial Converter-  This document details how to build your own SHARP palm-top/hand-held to RS232 serial converter.  In summary, this device allows the SHARP range of hand-held computers and pocket organisers to be interfaced to (almost) any computer which has an RS232 serial port i.e.  e.  IBM-PCs (or compatibles) , Amigas, SUNs, other UNIX machines, etc __ Designed by Andrew Woods

Power Conditioning for Notebook & Palmtop Systems-  AN51 Notebook and palmtop systems need a number of voltages developed from a battery.  Competitive solutions require small size, high efficiency and light weight.  This publication includes circuits for high efficiency 5V and 3.3 V switching and linear regulators, back light display drivers and battery chargers__ Linear Technology/Analog Devices

SHARP palm-top/hand-held to RS232 serial converter-  This document details how to build your own SHARP palm-top/hand-held to RS232 serial converter.  In summary, this device allows the SHARP range of hand-held computers and pocket organisers to be interfaced to (almost) any computer which has an RS232 serial port i.  e.  IBM-PCs (or compatibles) , Amigas, SUNs, other UNIX machines, etc __ Designed by Andrew Woods

TomTom One V3 connector pinout-  The TomTom data connector uses a non-standard 2.5mm audio style jack that has four poles on the inside and two around the outer sheath.  I have been unable to find a convenient source for the connectors so will remove and replace with a cable to mate with a Digilent PmodRS232 adapter to perform 3.3V TTL to RS232 conversion during debugging __ Designed by Peter Johnson

Unidirectionnal, Op-Amp-Based Interface-  This is a very good interface for unidirectional purposes.  It works with many computers, but not lap/palmtops.  Its simplicity makes it very popular. __ Designed by Damien Douxchamps < d douxchamps  AT tele ucl ac be

Universal Serial Bus Power Management-  App Note 17 --Universal Serial Bus Power Management __ Designed by Micrel

Wireless local network for PalmPilot (large PDF)-  Not English __ Designed by Jan Beutel, Tobias Bösch
