My Steampunk Pith Helmet with an integral 12v laptop computer fan.


The helmet looking relatively standard from the front.


The helmet from the side showing the battery holder, cable and switch


The helmet from the rear showing the battery holder and switch


The helmet from the underside showing the metal cobweb that prevents the hair and the fan from coming into contact. The cobweb was from a child's toy. It is secured in place by heavy duty thread.


From above, showing the brass screws that secure the fan to the helmet and the holes where air enters into the helmet.


Showing the battery box with two 9v batteries wired in series. This side is normally covered with a lid that hides the batteries.


A close up of the battery box showing how the box is secured to the helmet. It also shows how the brass brackets are soldered to the tin can/battery box.

The fan is a small laptop 12v fan that is running at 50% beyond its normal rated voltage without an issue - Mfr. AVC  Type: C5010T 12m. It has been tested at 18volts and it runs well at that speed without overheating. The fan was very cheap indeed and is small enough to fit into the helmet. A larger fan could be fitted but this one is small and powerful. It has a standoff shroud that allows it sufficient room to suck in cool air and move it at speed over the head. The fan has been tested at 9 volts but it wasn't quite man enough to keep the head cool at those low speeds. Boosted to 18v it does the job. The fan gives a pronounced "whirr" during operation.

The switch is an old 1940s chrome toggle switch. The brackets are two copper rheumatism bracelets drilled and bent to shape, soldered to a tin can. The small tin can used to contain Bakers Yeast and has a plastic lid, the can has been drilled to create to holes for the switch and the cable. The cable is shrink sleeved and held to the helmet using brass tie-rings that are screwed into the helmet. The hole where the cabling penetrates the helmet is sealed with transparent mastic.

The end result is a good looking helmet that really cools the head on a hot day. The original pith helmets look great but in practice they are too hot to wear without cutting your hair really short. Even so, without the fan you are still soaking by the end of the day. With the fan in operation it then really starts being a useful and wearable helmet. It really keeps you cool!

The two batteries in series last a whole day at the very least when run at 18 volts. I have not yet run them for more than a day but they have been tested functioning for 6-8 hour stretch with faltering.

Please do give me feedback if you like/dislike my creation. The change is subtle and you will not discern any difference from the front. The wearer knows the difference, he is cool in all respects.

Oh! Yes!

What a wonderful combination of form and content.

The gadget is useful, looks steampunkovski and imbued with the spirit of steampunk.

I may have to look into this, the heat is the only issue with Asylum being on August bank holiday. Does this draw air in from the outside or simply circulate it within the hat?

An excellent idea, Sir!
I did think that I needed a fan in my topper during the Asylum, as it was rather warm, but the idea of fitting one to the old Solar Topee is rather more fitting.

I tip my hat to your fine hat!  Grin

It draws air in from the very top which you will see has four small holes allowing for circulation. It sucks the air through these.

I love the idea of this but have to say that my French-style pith helmet is my 'go to' choice for summer sun hat as I find it is already cool to wear, as well as being cool to wear in the fashion sense too.  (Do people still refer to things as 'cool' or am I giving away my age?  But the pun doesn't work if you say 'splendid' instead!)

Good moderating! and happy birthday.

I am just replacing all the faux leather with real leather straps and interior.

That's a very neat solution, and the battery pack fits really neatly onto the back of the helmet. It is so easy to overheat whilst in Steampunk garb and this is a very neat solution to that. I would also suggest gel packs that can be pre-cooled in the freezer could be used at strategic points around one's outfit (for example, under one's hat) to help combat the heat.

Miranda.

Testicle packs would be nice - I shall invent those, in brass. Testicle coolers. Who here would like to see these when done?

Or alternatively, do you have any Scottish heritage? If that was the case, a kilt worn in the traditional manner would give plenty of airflow. Probably not such a good idea to install further fans down there though - it could all end in tears...

I will have to parse your question very carefully before I reply...   Shocked

So, the idea so far is for two induction tubes (Dyson inspired) blowing remotely-generated air via ducting from a compact turbine or electrical fan. The turbine would generate heat so that idea is a non-starter. The fan is a possibility and it could be fitted to a sporran but then the cooling effect of a kilt would probably be a better bet. Now I begin to see why testicle cooling has not already been addressed by a large number of devices from the likes of Dyson, Hoover, Electrolux &c.

Dyson must have sweated many pints before he realised that there is an insufficient market for testicle-cooling devices. Given that 50% of the potential market isn't even interested in such advances is enough to dissuade even the most fervent of inventors.

I could try a kickstarter - sounds painful in context.

Now, a fan or two plus a kilt might just provide a steampunk hovercraft... or at least a spectacular sight!
