Open Source and Open Standards at Home

| Is there a leading example of an Open Source 
| software company?
| Red Hat is an example of one of the best known 
| Open Source companies internationally. They 
| commercially exploit Open Source technologies by 
| providing support and services around a 
| technology platform called Red Hat Linux.

| The camera draws over 350mA@12V and thereâs no reason why I
| need it permenantly on. Iâve connected one of the Phidget
| Kitâs outputs to a simple transistor/resistor/LED circuit,
| with a 12V supply passing into the transistorâs collector
| pin, through the transistor, relay input and resistor. Then
| Iâve connected the cameraâs power over the relayâs output.
| The power on and off for the camera/LED are now through
| setting the boardâs digital output 0 to 1 and 0
| respectively. Power consumption with no movement has now
| dropped from 1.25A to just under 0.90A. Iâve also put all
| essential USB hardware on one usb hub and all optional
| hardware on another (USB to TTL adapters, sound adapter) on
| the other. The optional hub is also on a relay now on the
| opposite side of the robot, and this now reduces idle power
| consumption from 0.90A to about 0.50A which Iâm happy
| with.
