My startup, CloudFab, is doing well. I'll have more to say about that in a few weeks.

In my spare time, Hackety Hack is coming along, got a release out for Christmas, hoping for 1.0 early next month.

Then I have one more small project that's still secret.

Earlier quoted context omitted.

You can possibly get rid of the pair of 9V batteries by using a floating ground that you make with two resistors.

But then what would he use for the voltage source, + and - 4.5V? It appears he wants the + and - 9V available for the amplifier. But my EET is extremely rusty.

The 5 V from the USB.

Leave the opamp with it's ground connected to the joint between the two resistors, choose the bias so it drives the output from the -2.5 V the opamp sees (which really is the 0 from the computer) to the +2.5V (which is the +5 of the computer).

I have the following domains: http://blackhatsystems.com , http://bluehatlabs.com , and http://policyworkbooks.com . Does anyone have ideas for them or want to collaborate? Drop me an email.

I've got joytouse.com and notlit.com

(I agree, the first one seems like it would sell devices for hedonic pleasures).

Been working on open sourcing a PHP framework I created a while back. Uses MVC, but the primary goals are to be lean and schemaless. It pulls columns from the database and assigns them to variables dynamically so you don't have to update the schema and then worry about the database (most frameworks require you to flush and rebuild). More to come in the next week. It can be found here if you're interested:
