The perfect accessory for a hot-rodded PC (or one that
you would like to appear hot-rodded) – a set of headers
that emits a deep rumbling roar when the computer
starts up.
Upon pressing the power switch, the simulated whirr of
an electrical starter motor engaging is emitted, followed
by
the chug chug sound a large displacement V-8 engine
turning over. Once the POST is complete, the deep
throaty roar of a heavily breathed on engine with the
throttle being blipped is emitted. As the OS loaded, the
roar would reduce to a rumbling idle that would slowly
fade out.
As an added bonus, the headers would include a ducted
fan ventilation system to help keep the PC's internals
cool. Available in nickel, black nickel or powder coated
in a variety of colors.

I would rather hear a low hum gradually building into a
whine, like the sound of an aircraft engine starting. Add
the crackle of electricity and a whole panel of
blinkenlights. |

Shirley what is needed is a Coffman starter? And why
use fake sound effects when you can have the real
thing? Just use the starter cartridge to drive a
piston that presses the "On" switch. |
|
| |
Actually, I would really like to see a Coffman starter system for
cars, like they used to have for many large vehicles. It would give
me a little glow of happiness if I could walk out of Waitrose, load
my shopping into the boot, whip out a belt of cartridges, drop
one into a little breech block and whack it with a finely-crafted
hammer. |
|
| |
They have a very good fire engine museum in
San Diego with an old steam powered fire
engine which was started by setting off an
explosive charge in the firebox. |
|
| |
I have both a Coffman starter and a derelict Honda Shadow
in my garage, and now I have an idea that will likely result
in a fresh spousal mandate... |
|
| |
If only I can somehow work an Apple IIc into the mix... |

<wonders if you could get one of those little Honda generators into an iMac G3 after replacing the CRT with an LCD> |

Presumably, a model aircraft engine could be
coupled to a small dynarator to give a hundred or
two watts. |
|
| |
Does it come with an old fashioned crank? |
|
| |
I don't know - I think [Vernon]'s pretty busy. |

Err, no. Model aero engines are usually in the 3 to 5 cc range - a 300w generator generally has a 35 to 50 cc powerplant. Given that small units are (maybe) 35 - 40% efficient (small devices exhibit poor efficiency), the engine needs to put out about 1 kW. The classic Honda E300 has a capacity of a bit over 50cc. |
|
| |
A 35cc chainsaw engine delivers about half a kilowatt of useable mechanical power at the output shaft. |
|
| |
A 5cc model aero engine, given installation losses (quite a bit of which will be the forced-draught air cooling) might under ideal circumstances be able to produce 20W of electrical power; enough to run a notebook computer. |
