Updated Tablet news

by on May.28, 2013, under Uncategorized

Hi all,
I have added more features to my tablet. The batteries are in parallel, so the load is shared from the screen and the RPi. A switching 12VDC to 5VDC regulator replaced a very warm LM338 5A linear regulator. The switcher is from a cigarette lighter to USB car charger. It runs very cool in the case. A battery charger was added using a wall wart 12VDC @500mA. I connected an extension cord to the wall wart and fed it outside the case, because I don`t want to carry another charger around like cell phones and iPads have. Just a cord and a wall outlet.

The cigarette lighter plug is active and has a 7.5A fuse just in case.  The lighter port can be used in two ways, power supply and 12VDC charger for charging the internal batteries.

Switches have been added for the master power from the batteries to the rest of the tablet, screen power, RPi and USB hub, and internal battery charger.  The switches get the user full control of th tablet.

future enhancements

A kick stand.

A cord reel like a vacuum cleaner.

A pair of audio speakers with amplifier.

Hello world!

by on Jan.17, 2009, under My articles

Blogger here this is my first time blogging.  I’m adding this blogging to my web site to test this functionality.  I don’t really have a use for blogging to the World!  Anyway this seems like a really nice tool to use.  The editing seems OK.  I’m using Joomla now for content mgt and it seems to have all this same features plus more.

Joomla seems like a better tool to use for blogging.  I like Joomla’s PDF download of articles.  WordPress does have a comment feature which would allow a comment on each post.  That is not in Joomla.  Joomla has a easy way to add calendars and events, plus all sorts of other powerful plugins, so that makes it better than this.

I looked at some other people’s blog sites using WordPress and I really do like the comment feature that can be used.  Seems like a faster way to get people using the web site.  I will continue to investigate this as a use for me.

I’m doing a little editing here to try out some functionality.
