Optical Rotary Encoders, Magnetic/Eddy/Capacitive/Hall Effect based Non-Contact Joysticks, Makes Human An analog Interface with Digital Output.

For the people who type with two fingers; A Circular Keyboard is right. A Capacitive Touch Gesture Pad can replace the Mouse. Health & Ergo.

The Apple iPod touch is an Academic Example of Design Engineering approaching ideal Man-Machine Interface.

Personal Computers, Netbooks, Portable Communicating Devices, Remote Controls are where Usability Issues abound, and can be studied/remedied

Usability and Ergonomics of Electronic Consumer Equipment, product risks and safety are best studied with very old and very young people

Wireless Mouse with capacitive sensors may consume less power, no batteries works on a Supercap, Connector-less ferrite dock for recharging.

Wireless mouse rechargeable battery can recharge while moving on the Mouse Pad made of Ferrite/Ceramic 1' Sq with Power Hot Spots every 3".

Flexible Ferrite, Silicone & Ferrite based Solid emulsion. Can be made as computer table mats to charge the supercaps of peripherals. The Energy Efficient Wireless Peripherals can just be placed on this mat to draw the power without wires. Wireless power and Wireless Data.

The Axial capacitors like Metalized Polypropylene MPP are more reliable in comparison of their radial counterparts of same voltage rating.

Also note 440V AC Continuous rating reads and translates differently than 630V DC Max. Overrating is an important step in reliability for engineers.

Radial plastic caps, in mass production, due to various inconsistencies in production or quality measurement, are not recommended for high voltage unless its is a Manufacturer known for long term reliability and quality track record.

The radial caps when being wound, stretches the film/dielectric or weakens the dielectric at some areas as the turn is sharp, top/bot. This is possible unless the winding machine relaxes strain around the turns. In a Axial that may not be a problem as the film has more uniform stretch. The other reason could be that the Film is wrapped a little on corners or compressed on epoxy impregnation. It could also be low quality non-uniform PP material.

Components Manufacturers, especially in china have to spruce up a Raw-Material and Component Quality, not by red-tape but by actually improving the manufacturing and procurement processes, as the quantities involved are huge. 

I am glad to announce another attempt by me to be Social. It is hand made out of Wordpress and Buddypress. I cannot Take on facebook, twitter and google plus all by myself. I am forming a e-Jedi Grand Council.

Elektrick Jedis Grotto


Let the force be with us and me too.

This is where  Elektrick Jedis  meet each other and discuss Electronics in a Online Grotto. You are welcome to join and try, i am trying to set it up to go smoothly. This is a Social Site using WordPress and BuddyPress. It is a bit slow and i am working on in to improve, The features are tidy, this is very promising.

Features - Profiles, Activity - post image, url or video. Forums and Groups to discuss and collaborate. Group Wiki Docs to write or manage group projects/plans. Link Web Resources to create tagged web links.

Private/Public Messaging and Real Time Chat. Then to cap it all  a Wordpress Blog.

(Please note i am using  "cap it all"  or like "crown it all" it a positive way. That is why eJedis are different)
