Cyborg zombie evolution

Picture of Cyborg zombie evolution
It is well known from the age of steam to the age of steampunk... whether it is cool, creepy, cute or all three at the same time, bringing a creature to life takes electricity. In the case of this cyborg zombie as single galvanic cell, known as a "battery", even in exhausted state, is sufficient. This instructable wow to do this as a "no soldering" joule thief project for children aged 6 to 99.

This Instructable is a tribute to the following great Instructables:
zombie friend?
Cat Burglar Joule Thief
Give the gift of Robot Invasion
and to the simple fact Instructables are great source of inspiration.

At Evil Mad Scientist you can find a circuit diagram and an explanation on how the joule thief actually works. Another explanation on this blocking oscillator (more correct according to some) can be found here.

When making the cyborg zombie in a workshop with children you should do some of the steps in preparation depending on their age and experience. For 6-year-olds I do step 2 to 4 in advance. More experienced young builders can do it all by themselves.

A workshop I gave October 10th, 2009, in time for Halloween that was a good reason for an update of this Instructable: in the last step I added a short report on a workshop . I included some inspiring pictures on how the cyborg zombies evolve in the hands of children.

Awesome good idea :D
This is SO cool! Where did you get this idea?
masynmachien (author)  rabiddemonweasel3 years ago
Thanks.
The idea came from the Instructables mentionned in the intro. I wanted to combine the great zombie friend? with something more technical. The Cat Burglar Joule Thief showed how to combine a Joule Thief with a soft doll. From the Give the gift of Robot Invasion I already had the idea of making an "army" of some kind of cute robots, or in this case cyborgs.
 
Cool! Thanks!

I think you mean magnets with holes in them-- drilling holes in batteries sounds dangerous.
I agree with him.
masynmachien (author)  codongolev4 years ago
Indeed, I mixed up the words. I corrected it now. Thanks.

really nice, the magnet idea is absolutely amazing, i had never thought of doing that! now i realise that... its amazing!

prolly a good gift to give somone :P

It's a lot of effort to not solder. Five minutes with a hot iron Vs. hours of collecting connectors, magnets, whatnots and stuff...... But nice instructible, but I'd prefer to have a nice, big, colored schematic.
masynmachien (author)  Unit0424 years ago
Sure, soldering is a lot faster. I made it this way so that young children can make it, with some guidance. A hot iron is a bit dangerous then, as I am talking about groups of 20 children aged 6 to 12. Also I would need several soldering "stations" with a decent fume extraction. Soldering everything advance, takes the fun out of it for the kids. Actually, I admit that when I do step 2 in preparation of a workshop, I do solder the magnets to the wires (no holes needed) and I omit the "halved" contact by soldering the resistor to the B(ase) lead of the transistor. Please feel free to make a big, colored schematic. I am sure it will be welcomed amoung the many joule thief builders, as I only found black-and-white schematics.
6 year olds and soldering irons don't mix, so I get your point.... The color scheme on the schematic depends upon the idea being illustrated: oder of assembly/voltage potential/current flow/separation of circuit blocks could be conveyed with color. The simplest thing you could do is go to the evilmad scientist site, copy their black and white schematic to MS Paint(or other image manipulation program), with permission, then trace over/fill in segments of color.

cool. i made a high voltage joule theif, these are cute
it is so cute! im gonna try to convince my parents to let me make one

Thanks. I fixed it.
An excellent mix of electronics and craft. I'm definitely making several of these.

Those are adorable. In fact, I think I have to make one!

what, so 100 yr. olds can't do this?
masynmachien (author)  EnigmaMax5 years ago
Well sorry, but I never had any 100 year olds in my workshops, so I must admit I do not know for sure. Come to think of it, I never had any 99 year olds in my workshops either, nor any 98 year olds, no 97...
well, its not really fair to the senior community to limit their possibilities of making things on this site. in fact, I don't think its fair to limit anyone of any age the potential of building. but that doesn't mean they shouldn't be supervised...

Cool stuff. The basic circuit is well known in power electronics as a "boost converter", in this case with a much simplified transistor control. The frequency and duty ratio of such converters is a complex function on man y parameters: input (battery) and output (LED) voltage, coil parameters (inductance, inter-winding capacitance, coupling factor), and transistor characteristics (including its parasitic capacitances). Many of these parameters are also dependent on temperature so ... The best way to make it work is to go for trial and error, e.g. to experiment with the number of windings and the size of the coil core. If you really want to make a full analysis, you may find yourself end up writing a PhD thesis ...

Eh... sorry, but Polymormph seems to do on http://www.instructables.com/id/quotDeadquot_Battery_Lamp/. Actually your explanation is very good, while still being quite short.
I would look forward to the ultimate explanation based on joints efforts. For me, what is missing is what factors determine the frequency.

I thought the "more correct" parenthetical referred to the name, not to the explanation.

Awesome job, they look fantastic!
