Small off-grid for the garden...
http://www.instructables.com/id/Cardboard-Savonius-turbine/
Plus the solar rig built at hackspace.
Project Plans: -
- achievement awards for hackers
- gentle path for acquiring skills
- "You have unlocked a new achievement"
- badges, certificates, icons!
- laser induction
- woodworking tools induction
- sewing/knitting machine
- welding and metalwork
- circuit design and etch-tank
- Workshop: Electronics From Scratch is Easy - a Nottingham Hackspace geek's introduction to electronics and why you can do it!
- machining
- shoe repair - glues, heavy duty sewing, sugru, bicycle tyres
- put wheels on things!
- put faces on things!
- Inappropriate Technology
- bike trailer
- car trailer
- like the ones my dad made
- steel angle from bed frames
- indespension units for wheels
- http://www.indespension.co.uk/b2c/app/I00660?ZSUBCO=033&Z1MACO=181&PGMN35=005&slnk=1
- I think these original Mini ones are the thing: http://www.indespension.co.uk/b2c/app/I00080?PNUM35=SH012&slnk=1
- submarine
- ERTs
- http://www.gai-tronics.org.uk/products/ert.htm
- stick a PC at the base of each and tap into its serial comms
- build a SIP phone from one end of the HackSpace to the other with the two phones perhaps mounted outside the front and back doors!
Fabrication - object printing
- T-shirt printing
- Culture references
- "Outside Context Problem"
- "Special Circumstances"
- "I can't believe it's not better"
- Laser cutting
- CNC machine
- MyDIYCNC
- Martin's CNC machine
- 3d Printing with RepReap
- just laser printing
- circuit board etching
First use of laser cutter: -
- Veralite board 3 dingdongs of the power dial and speed of? melty
IRC Bots

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...

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. I cracked open the ballast electronics of a broken CFL (Compact Fluorescent Lamp - an energy saving light bulb) to get at the ferrite and NPN transistor that live in there! I got a nice-sized ferrite toroid and an MJE13001 NPN transistor (these things seem to be in most CFLs).
I wound the ferrite toroid with a pair of fine wires stripped from a PC CD drive audio cable and managed to get 7 winds neatly in there.
BTW: here's a good write-up on CFL electronics: http://www.pavouk.org/hw/lamp/en_index.html
My random NPN transistors: -
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!
Vikay LCD module
Also other LCD and VFD displays

- 16 pins
- same as the one on Cheesoid?

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!
- I prefer DONE RIGHT!
- 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...
As a phrase I just wasn't getting this at all - it only made sense if you already know what's behind it.
