Does a good job
seen this on another website, heres a step by step guide>



what you need is a non metallic container (mug) put a folded bit of aluminium foil down one side of the mug, connected a wire for the negative (note in my pic i have the red and black leads the wrong way round GEARKNOB GOES TO BATTERY POSITIVE, FOIL GOES TO NEGATIVE). i attached my gearknob to a bolt and hung it into the coke (i used diet but i dont think it matters) THE GEARKNOB AND FOIL MUST NOT TOUCH.

the best way to do it is get your gearknob hanging in the coke and make sure theyre not touching before you connect the battery (batteries).

For my first attempt i used two batteries for 18v and got the results below after about 1 minute, a bit blotchy and not really the colour i was looking for.




so i added another battery and put it back in for another minute..... getting more like it now :thumbup:



i then started trying again, adding more and more batteries, but it just started going a bit grey. i sanded it down with a bit of wet and dry in a drill (took about 30 secs) and tryed a few more times. to get it looking like below i had 7 batteries connected together (63v, i think voltages upto 150v are used) and connected the power for about 3 secs, span it round 180 degrees and gave it another 3 secs.this was because i found the side nearest the foil changes colour a lot more quickly.




The idea is that different colours can be gained by using different voltages, but you would usually have an adjustable power supply and better solutions than coke to get a broad spectrum of repeatable colouring. even so, just with the batteries and coke, i'm sure you can get good results by experimenting a bit........there's a lot more info out there on this, i have barely touched the surface.


...If anyone tries this, post their pics up

awesome. Looks like ive found something to do tomorrow!

[Bud]

That's awsome!

[rico83]

That is impressive

Thanks for sharing.

i good write up here : http://astro.neutral.org/anodise2.shtml

[type r girl]

that very clever and i might have to try that.

Dont buy coke myself - would lilt work?

Mmmmm Lilt, with a totally tropical taste!

[mjhamilton]

that is pretty cool... fyi if you make the foil go around the cup you will get an even coat in one go, although of course this will make it all a little dangerous trying to stop contact :thumbup:

... does your now purple knob still taste of coke when you lick the tip?

Do different liquids produce different funky effects - if so then tizer would be :cooldude:

How so? In the picture contact is made and broken at the battery terminal.

Tempted to give this a crack, just need to find something I want to coat..

the elctrons flow from the foil in the cup to the metalic knob and the reaction causes the coating on the surface..... you see the foil it only on one side of the cup.. if this were to run around the entire circumferance of the cup there would be an even coating...

.... however you would need to start again and work out the number of batteried required as the resistance would be greatly increased...

Forget my babble and stick with the tested method above.. this rocks and it is noce to see old school chemistry being used in the garden shed :thumbup:

Sorry, I understood that part. I was meaning how is it more dangerous if the circuit is made and broken at the batteries?

oh I see... ok.. when you put your knob in the coke you just need to be a little more careful when you connect up the battery that's all.,

im struggling to get this to work.

Did you have your gear knob polished before hand? I've tried sanding mine a little first using wet and dry and a drill.

Even using 8 batteries nothing happens, and you said it happened in 3 seconds with 7 batteries

.

[Neel]

Good idea, got a spare gear nob, was thinking of selling it,
might give it a try :thumbup:

You'll need to sand it more than that. You need the ALU exposed, it will be laquered (sic). Looks like it was polished first.

[*nub*]

anyone else bought a brand near skunk2 gearknob and had the colour fade away after a month?

[samg1988]

well, I polished my knob for a good 15 minutes with a drill and 1500. No laquer in sight. But still, nothing. Just a sticky knob.

Maybe mines not titanium for some reason. Pre-facelift EP3.
