Desktop Computing Future

Wish we could Stop making Desktop Computers that are Energy Guzzlers by 2020. The Laptop/Notebook Electronics Design Architecture could be Ported to the Desktop Computer Physical Framework.

This makes Battery Operated Lean Desktops that can always be on Float Charge. Temporary mobility and convertibles are also possible. Power Failure proof.

A flexi ferrite table cover to wireless charge mouse, printer and keyboard batteries. An additional Lan with Wi-fi to network with all the Peripherals. This gets rid of the Cable Clutter and Device Drivers for Peripherals.
 
Desktop Computing Future

Device Interface

Wireless USB has not still been adopted as a standard for peripheral interface. (not to be confused with Wi-Fi USB sticks). BlueTooth is good but does not completely address Easy Peripheral Interface in terms of usability etc. This may help the Desktop Comp.

Nettops use less power and are the Desktops of Tomorrow, with cloud computing and wireless storage these are the essential devices to go to Green Computing and the Client-Server Architecture with the Cloud in mind. We need both Intranet-Cloud and Internet-Cloud.

Each PC should have Two Wi-Fi. One for Device Networking and the other is for Web and Networking. Device Networking means adding Smart Peripherals without Drivers. Example Wi-Fi External HDD and Wi-Fi Printer.

HardDisk

Rapid on off Power can Damage Hardisk. Transport of PC over rumbling Terrain, PC or Notebook drop on Hard Surface, Impulsive Jerks of Table on which Desktop Comp is placed; can mean, that your data and device is a goner. Maybe Desktops should use the more mobile Notebook Drives or external portable drives (technology), as these consume less power and are more robust.

Desktop Computer Reforms

Please pay attention to an earnest plea from a person who has pulled cards and ram from xt-at 286-386 days. Some people are innovating, at least follow those lines. Help make Desktop Computing Obsolete.

Tablets, Nettops, Netbooks and Notebooks are the future. Low power consumption, wireless, light, modular, low voltage.

Desktop Computer Reforms

If you are still fanatic about Desktop Computers, here are the ways you can move in the right direction, from legacy to Futuristic !
  • Make the internals of a Desktop computer, Dust Free. 50 Microns particle, not any larger.
  • Make the Desktop Computer SMPS and design Earth Free, Two Wire Only, No Y caps.
  • Let it work on a 12-24 V DC Bus/Grid Standard, With External Connectors. Adapter Outside.
  • No Fan should be used, No moving or Rotating parts inside, No Wires, good connectors.
  • Modular Plugin, Stackable System to be used for External CDROM/DVD and HDD Drives.
  • Flash Integration Internal for main OS Firmware and External Flash like HDD Stackable.
  • DVD, HDD, Flash Expansion on USB Removable or SATA Stackable like Building Blocks.
  • For a Whooping One Grand, People deserve a Backplane Plugin Architecture in the Desktop.
  • Box, LCD/LED Monitor, HDD, Wi-Fi must not consume more than a Maximum of 50 Watts.
  • All Internal and External Modules and Devices should go to quiescent state, non-obtrusively.
More to come, as i try to fix and break some more ...

Present Day Work Time Utilization of man using Desktop Computing. -
  • 30% Updates and Installation of The Operating System, Safety Issues.
  • 20% System Admin, Networking, Application Installation and Updates.
  • 10% Hardware Problems, Interfacing, Sharing, Wire and Port Issues.
  • 10% Physical and Mental Fatigue and Stress Caused by above, plus Coffee.
  • 30% Productive Work Done. Means work done in a Job or Profession.

Tablet Ándale - HandHeld Computing

Just some study i made, only the understanding or conclusion here. For the years 2012-16. Low power consumption means we all last longer, healthy, si no, carbon footprint, Ser hombre bueno.

Tablet Types - dapj tech

Units and Metrics -

Screen Size is in Inches. Carbon or 'caramba' is the color code to emphasize the energy consumption.
Power is the zap or punch of 'P4 at 2 Giga Hz with 1GB Ram' - Let us say, this configuration packs One "Gonz".

Energy is the juice it takes on the average browsing, word processing or youtubing, in Watts.

Tablet Ándale - HandHeld Computing

What you saw and What you got

If a Video was created in a Lower Resolution it is no use showing it at a High Resolution. A Video created or acquired in High Resolution can be shown in any lower resolution.

Showing a Video in High Resolution in smaller devices will not help much. This is the limit of the Human Eye itself. So do not waste bandwidth and processing power in very small devices. 

Gracias Senor or Senorita, for the patient reading.

Adiós Amigos, go for your Siesta.

As for me .....Ándale, Ándale, Arriba, Arriba.

I see a Splendid Future for Tablet Computers as they consume low power, portable, wireless web, ergonomic and affordable. They leave less eWaste when the product is disposed and it does not stress the Health of the user.


Tablets and Slates based on OpenSource OS. Even OpenHardware Tablets. This is a collage of various blurbs of mine in my other pages. An Home Appliance for Consumer Computing.

Why Tablets ?
  1. People want computing to be Personal and Portable and hassle free. With less Maintenance Tasks.
  2. Low Power or Green is the order of the Age, Fuel and Energy is not as easy, expensive and depleting.
  3. Low Carbon Footprint, The global carbon footprint of making, selling and scrapping tablets is low.
  4. The Technologies have evolved in Flash, Battery, CPU, OS, GUI, LCD, SMT and most Electronic Parts.
  5. Online - Web Computing and Cloud Computing offers Safer Storage and Powerful Web Applications.

iGoogle Widgets and The First App Store

iGoogle the father of Web 2.0 - iGoogle shaped and inspired many technologies. To name a few, The Web UI Frameworks and the Community App Store Idea. Even though the "Desktop" was just a webpage and the apps were web widgets.

The API access could be any web app or Google Service. I made a Online Desktop in its memory. The Jot Desktop

iGoogle the father of Web 2


The Chumby Device posted earlier had this Chumby ARM Board. You could program the Widgets that could scroll or cycle thru the screen. Like News, Clock or Weather. The App Store was available but the device had to be configured unlike the Apps on the Phone today, which is much easier. This was the first App-Store that worked with a Touch-Screen.

Then ARM core deserves a lot of credit. but the 300MHz board you see below was an early step. The 1GHZ ARM that came a bit later makes the Tablet a powerful Web, Gaming, Office and Utility App Console.

Chumby ARM Board

The Desktop Computer wastes a lot of power but a HandHeld is green, sustainable. A 10" Tablet is the best way. So do not wait buy some Tablets and Netbooks and use your Desktop Computer when necessary.

All flash Field Replaceable

Make all Flash Memory in Home Appliance, Gadgets and computers - Easily Replaceable and Field Replaceable. If possible replaceable by layman like batteries.

Many people are having problems and high costs of service, as equipment and devices made over the last few years have flash that is hard to replace and source.

The only flash that can be SMT and Soldered could be the ones loaded with "Static Software or Firmware". That means that area of memory that is subjected to very less write cycles. Even Firmware that is frequently updated should be on an replaceable module.

Make All flash Field Replaceable

I first experienced flash usage in a 8051 based Fuel Dispensing Unit we were developing in the late 80s. It was a SEEQ chip with 10K Full Erase/Write Cycles. it was a pin-2-pin replacement for 2732 UVPROM (kilo bytes). It later needed a piggyback timer.

Flash has developed immensely since, It lasts much longer and goes to Giga Bytes Storage. Giga Byte was BigData in the 90s.

Also Frequent software updates must be written as an overlay over the "Static Software".An External SDCARD as a database/code source for the updates.

Keep all frequently up-gradable parts of a firmware in a easily replaceable device called "DynamicWare" which includes the Interface/Internet areas and all that is susceptible, vulnerable, UI and young-and-growing sections.

So we have StaticWare Flash for OS, DynaWare Flash for Updates/Fixes/Apps. and External Flash for media/apps. The StaticWare alone can be SMT Hard Soldered into PCB, this should have enough smartness to upgrade device on Wi-FI with barebone GUI.

Gizmos and Gadgets that consume more batteries can be supplied with easily pluggable battery and spare battery with charger. This way the battery can be quick replaced when drained, rather than charging the device. This reduces system downtime.

Usability of Front Panel Controls

I once worked in Tek for a very short period. I got to experience the 2235 and 2465 analog scopes and their controls. The 2465 was a 400 MHz Digitally Controlled Analog Scope.

I also used the Plugin Scopes and Calibration systems that were Tek Culture and Tech contribution to the Instrumentation world, it probably evolved into VXI-PXI as uC systems took over.

I also had a chance to look at DSO/Logic Analyzers and the just developed TDS Series.The older tek analog scopes made me understand about usability and panel layouts. Many controls are inevitable in a Analog Scope with Electromechanical Interface.

Usability or Ergonomics Review

In a Digital World that can be largely changed using the Monitor and Trackballs. The older BlackBerry phones are also good study for usability before Touch Screens came.

delabs Experiments

delabs Web Widget and Application Interface Usability Experiments 2003-2008

In 2003 i tried some experiments in Web Interface. I also converted some mini DHTML Widgets i made in 2000. These i later added to iGoogle too. In 2000 it was a Midi Player later an Alarm Clock when iGoogle came. Then a Metronome and Mini-Notes Holder and a Text-Database driven Music Player.

delabs Web Widget and Application Interface Usability Experiments 2003-2008

Talking of Touch Screen, i had seen a  Monitor in a Universal Pick-Place Assembly Machine. A Huge Pneumatic System, Not a SMT, there was no SMT then. This monitor had IR LED and Opto Transistor Array over the monitor. That sensed the finger Probably.

Capacitive Touch Screens and Accelerometers have given a new dimension to Ergonomics.

Then came Euro controls for Consumer Electronics. Like remote controls. Look at the National Panasonic VCR Remote on the right. It could be in the 90's. It is so easy to operate the VCR, you do not need a manual. Flap a Lid and you have many things to do, including control any brand of TV in tandem with the VCR.

Software or hardware it is the same thing. The way the Common man sees a Gadget, like a Lamp Switch or a Water Tap.

The HTML5 thing also is in the same direction, which empowers Web Designers to make Usable Apps and Sites not just Flashy Mazes where one can get lost for eternity. Some of the sites i built are like that, Labyrinth of Docs which only the Search can Reveal.

PCB Prototype by Cu Deposition and Sn Plating

Take a Blank Epoxy Card. No Copper, just the glass epoxy card. It will not be copper clad. I am trying to explain the concept. The Glass Epoxy card as you know is Epoxy (Like Ciba Araldite) with glass fiber as filler. Maybe new technologies have come now. The fiber is for Reinforcement and Epoxy you know is a Marvel of an Engineering Material.

EE Design Library - Electronic Product Design Resource.

PCB Prototype by Cu Deposition and Sn Plating

PCB belongs to AVR JTAG adapter - MadWizard.org

In those days some people told me that these epoxy with glass fiber and iron flakes as powder are used to repair aircraft/spacecraft. It could be cast into a shape and even turned on lathe for making custom replacement components.

This nudged an idea, If we Screenprint a Mixture of Epoxy + Fine Iron Dust + ? over the blank Glass Epoxy card. The positive is used not the negative. That means Pads and Tracks on Positive create an Image of Pads and Tracks of this Epoxy/Iron paste on Glass Epoxy surface. Now Screenprinting done, let it dry. We can also be print a thin layer of epoxy pcb pattern and blow iron dust on it.

Dip this Printed Epoxy card with this iron/epoxy pattern; into a Copper Sulfate CuSO4 + ? + ? Solution. The ? has to figured by chemical engineers. I used to be good at Organic and Inorganic Chemistry, when i was young. The copper replaces/plates the iron powder and with some electrostatic and electrochemical methods the copper layer grows over the entire tracks and pads quickly. Now the card is Tin Sn plated to complete.

A single Prototype PCB is ready and no extra copper wasted. Copper and Tin was deposited.
