"Camodelkin: Kapka, or handheld hardware-software system with their own hands

C the onset of spring - the pores of hope, change, bursts of creative enthusiasm - HPCru is a new section - diy. Under her banner we offer to meet anyone who does not stop at buying a handheld communicator, a smartphone or any other mobile device of their dreams and continues to independently develop the purchased product in search of the ideal. Accepted for consideration by the stories with photos of the original solutions, including hardware changes, as well as software products of its own production is called "the soul" (not for money!) Who made ​​your life better with a PDA and more fun. In return promise to publish a story on HPCru, and, therefore, known in some circles:) Please send your letters to editor@hpc.ru, but now present to you the first story. Now the world is very small PDA keyboard device that does not fit with my idea of ​​a perfect PDA. Even when he was palmovodom I'm dreaming of a full keyboard. A little about myself. By my life, I "tourist weekend, often traveled to the woods outside of civilization, but to be severed from the virtual world can not. Back in the old days, sitting in a tent and talking in ICQ, I started thinking about an external keyboard for PDAs. Variants with tiny buttons on the case of some models, as well as folding, folding, and other keyboard does not suit me. When it's time to upgrade, I already knew that I needed to be completely happy - USB-host. We are almost at the same time, I began Toshiba e400, Keyboard Dialog KP-102UH and Optical Mouse Logitech M-BT58. Issue with increased energy costs decided fairly quickly, thanks to the use of external charging from four AA batteries. One such kit is enough for one or two charging or three to five hours. "Dialogovskaya" different miniature keyboard and the convenience of a laptop keyboard and a built-in passive USB hub. But typing while the CCP is just lying on the table, it was not very comfortable, and cradle included was not available. Had to invent how to make a stand from scrap materials. Complexity was also in the fact that infrared machines should be in the field of view port of the mobile phone. In this model Toshiba is it outside the box - in the bottom of the left sidewall. Fantasy quiet winter night gave out a scheme of mutual arrangement of devices for different ... The first version of PDA hardware and software system, or, in abbreviated form, Kapka located in the original box from under the keyboard. To cover the box, I cut out the shape with compartments for PDA and phone number of a piece of foam, and closed the cover sheet from the usual black folders for papers, joining together a transparent adhesive tape.

Handheld hardware and software package, Version One

Have passed since six months. During this time the list of peripherals Kapka widened, prompting a desire to modify and "body." The current version is based on the cover of the student's notebook to flip units, freed from the past. Top clip is from a folder, which in life hold the sheet of paper, and now holds the PDA. Availability Stitched Windows Mobile 2003 SE with built-in screen rotation allows you to deploy handheld infrared down to landscape mode, and accordingly move downward GPRS-module:), whose role is make a phone Siemens ME45.

Restyling, second edition

In order not to touch the phone while a voice call, a headset. Active hub Genius UH-401 is powered from the same finger batteries hidden in the roll-stand for hands. To a hub connected to a keyboard, mouse, and Chinese media card reader on the seven types of memory cards. At the request of Kapka can connect and external speakers. This is going to set a few minutes, the main thing - do not become entangled in wires. Before you - its scheme.

Note. At the time of the scheme did not include an active USB-hub and card reader.
I must say that the creation of Kapka not require major infusions of money (buy more of the following is just a hub, all the rest had a desktop PC). Given the antiquity of the phone, as well as the anonymity of some manufacturers of devices, say the total cost solutions to be $ 400. Of these, the share of the PDA had 285 cu But that's not all. In the next creative plans - to connect a mobile hard drive 2.5 "20 GB, as well as the possible development of the next version of the design. Make comments, suggestions, and share his experience with me by visiting my website - 4pda.net.ru or friendly to all fans of handhelds forum on HPCru :-) And finally, let me advice. Do not consider such a product as a replacement for a laptop ... For lack of options Kapka can be a day or two to use at the cottage or in the woods, but this decision is not enough Magnifier from the old Soviet TV:) Sources, Materials:
