Joule Thief

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: -

  • 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!

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...

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

Tattooing Skill Share

  • workshop to fit the level of the attendees
  • touch on the theory, science, history, cultural significance, of skin marking
  • no humans will be tattooed!
    • bring a grapefruit or thin-skinned orange - this will be our "customer"
    • this will free us to concentrate on the mechanics
    • removes the need for a massive portion of the essential education in tattooing: steralisation
    • touch on cross-contamination
  • modern tattooing in a "shop" environment
  • the Huck Spalding book
  • inks, pigments
  • needle groupings for lining, shading, fine-line, special effects, etc.
    • laying in the colour
  • skin normalisation and stretching
  • healing and scarring

Tools Info

One day in Jan 2016 an enthusiastic brand new member was working on a project and asked me how I would cut something accurately. We had a talk about the options and we looked at the bandsaws one by one - they were all out of order. I tried to find out about the various statuses online and where I could find/get spare blades The wiki tool lists are out of date (understandably!) and not maintained (e.g. Tools/We_Have has no mention of 4 of our bandsaws) - searches find lots of old pages that nobody needs.

What people want to see is a live status page for the major fixed-down tools - the tools team can keep this reviewed and up to date. For reporting problems, I'd like to see a quick means that doesn't need a computer: -

  • Have a physical rfid box with say 6 buttons on it.
  • Member scans Rfid and presses button for broken tool.
  • Magic happens and tools team is informed via slack.
  • Member can be emailed for more information
  • Website hms tool status page is magically updated with red cross against tool
  • Github issue is magically opened to track the problem
