Various AI

Logging and statting

Who's in web indicator

Hackspace is ON/OFF web indicator

TODO

• Weigh components!
• New base, new alu motor brackets
• Motors: test drive commands with PWM enable line - power from AA batt pack
• test MICRO LED
• volume control from command line sudo /etc/acpi/voldownbtn.sh ??
• shutdown eeePC from command line "sudo shutdown now"
• IP publish with wget
• http://en.wikipedia.org/wiki/Situation_calculus
• test voice recognition
• new Java code on eeepc: add Mapping class
  • choose a grid size and calculate the requirements for navigating the Hackspace - could do dynamic map and discovery
  • "Unexpected item in the bagging area"
  • "Somebody move this wall"
  • "Somebody move this person" (PIR detection required)
  • http://www.societyofrobots.com/programming_wavefront.shtml

• When no goal start mapping the room
• Work on the IRC module
• ad-hoc commands using bean method introspection or BeanShell scripts

I have a 2N3704 transistor (rather than a 2N3904) so the Base, Collector, and Emitter of this NPN are in different locations...

• https://www.futurlec.com/Datasheet/Transistor/2N3704.pdf
• http://en.wikipedia.org/wiki/Bipolar_junction_transistor#NPN

I also have a regular 2xAA battery holder which somebody has hacked and is slightly melted on one side! I will use this as a single AA battery holder. So my toroid centre tap goes to battery +ve.

Project first build complete (with on/off switch) - upload pictures to the various feeds.

There's now a Joule Thief workshop!

Plan a multiple build with the various found components

My random NPN transistors: -

• BCY71 in a TO18 can PDF
• 2N4123 in a TO-92 plastic package PDF
• 2N2222A in a TO18 can PDF

Battery casings: -

• light-up Santa - lots of room inside - primed for hilarity
• Quartz clock - small and handy - shall do this one first
• plain 2x AA battery holder - boring - done that!

Stairway lighting

Sign: -

Don't get left in the dark!

The stair lighting automatically switches off after a while so...

Press the button before you go up or down the stairs (so you don't get stuck half-way!)

Vikay LCD module

DONE IS THE ENGINE OF MORE

Dominic's catch phrase!

• but DONE is not well defined!
  • I prefer DONE RIGHT!
    • but DONE RIGHT is not well defined!
• but MORE is not well defined!
  • MORE stuff to do? MORE problems?
• I don't think this works or me!
  • but WORKS is not well defined!
• ad-nausium...
