A prize for the first one to build one of these
BTW. the reference to the sandal might have you Australians stumped (like in the cricket - ouch!) but in the N hemisphere a Flip-Flop is what is referred to as a 'thongs' down here. A thong up there is a ladie's g-string.

Re: Fun schematic
Gday rob , I have printed and laminated the circuit diagram and it is prominently displayed in the "shack" but I am having trouble sourcing the pi resistor (any leads)?. cheers . mark VK2AMS
Re: Fun schematic
I'm sure a Pi resistor is just a resistor with a nominal value of 3.1415926535897932384626433832795028841971693993751 Ohms, plus/minus 10%
I see the Flux Capacitor is on there! I keep meaning to go into DSE on 1st April and see if I can convince a 'Techxpert' to look one up on the system for me. The 'radiocommunications techxpert' in the Penrith store didn't know what a PL259 was so I could well be successful!

Hi All...
Well come on, it is pretty obvious as to what it is....once the antenna picks up the signal....the Globe sends the image of the Bat onto a cloud....
Then I come running....

Here's the frame of a nice timber cabinet to put it in when finished building (about 1/5 way down)

Re: Fun schematic
I've built several circuits similar to this, even designed a couple and they all worked. I'm not sure what they did but they did it.
Just a suggestion for anyone trying to source the components as a couple is suspect will be hard to come by, is for the resistor network beneath the fishing float use a coil of galvanized barbed wire and trim for maximum spurious output. This could probably be substituted with a wet half grown echidna.
Your mileage may vary?

Re: Fun schematic
It will never work, half the diagram is missing !
Re: Fun schematic
I am not sure if Miami-Dade County will be impressed when people start digging up I-95 intersections for this...
I suspect it might cost a bit to post all that asphalt to Oz.

Re: Fun schematic
Rob,
There is something missing...... Where's the coffee pot?
All HAM's drink, some do coffee, some do coke (the liquid fizzy type) or tea, some even have a friend over... Mr Daniels (Jack) or Mr Walker (Johnny).
Maybe these need to be added?

Re: Fun schematic
I'm just wondering what purpose the cat has in the project - is this to facilitate connection to an amateur transciever? Might build one of these and when my new FT950 arrives, hook the project up, connect the radio to a dummy load and see what it does.

"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."
That's one hell of a solder blob though if the scale on the top left is to be believed..
Re: Fun schematic
And here I was thinking that the cat is a sacrificial protective component used when the circuit is mistakenly fed with AC rather than DC current. It derives from the experiments of one Thomas A Edison, who used AC to electrocute stray animals, to 'prove' the former's increased danger. http://en.wikipedia.org/wiki/War_of_Currents (in a similar vein note that the electric chair, using AC current, was developed by ex-Edison people http://en.wikipedia.org/wiki/Electric_chair )VK3FCJM wrote:Albert Einstein, when asked to describe radio, replied:VK2FRO wrote:I'm just wondering what purpose the cat has in the project

Re: Fun schematic
every f call worth his 50 questions knows that for aussie conditions the mouse in the batulator circuit needs to be replace with a wombat and the 11kg springy think needs to be increased to compensate for the increased resistence of the wombat. You have to recall the formula for springy things and wombats in series I quite like the design especially the test point where ACMA inspectors can test for interference ( touch tongue here)
F calls may indeed build this but under no circumstances should they attemp to operate it but if you do you should use a smaller 10W electric eel
First time I have very seen a working circuit example of a Politicians brain .

Re: Fun schematic
that should be put in the foundation handbook - it makes the whole thing a lot more clearer."You see, wire telegraph is a kind of a very, very long cat.

Re: Fun schematic
To further reduce power, replace the ballast light globe with a space heater (2 bar preferable, quartz seems to inject parasitic oscillations), or an ion laser tubes filiment. Then if you like, you can ionize that tube with the 500v and have a pretty laser lightshow each time you TX (attach a mirror to the vibrator). Smart constructors will add a sawtooth generator to the circuit to make the laser show into a basic voice oscilliscope. Saftey glasses should be procured for the mouse (which I thought was a cat), the bat, the beetles, and the electric eel.
this effectively turns the unit into a QRP (quite rotten politician) rig.

Re: Fun schematic
About that vibrator........If a particular unit is required, I can supply the data. Among the collection of data books on my desk at work, displayed in a prominent position, is my copy of the Vibrator Handbook. A few of my female colleagues have remarked on it, but have declined the invitation to peruse its contents. Can't imagine why. I've owned it since my early teens and it seems pretty unremarkable to me.
