The wife and I spent most of Saturday at a consignment auction. We spent alittle money and brought home way TOO much stuff... Nothing too steampunk... the best finds were a copper soda/acid fire extinguisher, a 1930's singer sewing machine (electric), and three old toy rifles. I think the rifles will be donors for future photon rifles!

Oh, no you don't! Get back there and buy that sparky thing AT ONCE!  Grin

Hum, I wont be over that way visiting rellies until at least  September... And Strathalbyn is a bit out of the way when I'm just going to Robe...

Holy carp!  All the stuff I find a flea markets/antique stores are no where near as awesome as the stuff you all are hauling!  Lucky buggers you.  The only thing I ever saw worth buying was a very nice Victorian couch akin to this one only in a seafoam green velvet that looked like it had gotten wet at some point and had dark spots of something (mold/mildew/whoknowswhat) on it.  They wanted 2500 for it though which is a little (about 2450) out of my price range...

A couple of pages back I mentioned metal halide globes, or rather, dead ones.

My friendly hydroponics chap saved this one for me, and promises to keep ahold of any more dead ones that come back to him:

(Photobucket seems to be rather arbitrary about the orientation of the pics; they were originally portrait!)

Basically they could be hollowed out, or small globes or LEDs added in for effect, or just connect a tesla coil (small) to the base and have plasma globe style tendrils coming off all the metal bits.

Just one note of caution - some of the metal halide globes contain a trace of mercury to get them going when switched on - mainly the sodium ones I believe. Check which one you have before opening them up!

I shall stockpile them over time for swaps if people are interested.

Same here!  I'm inclined to think it is largely a UK vs. US thing.  Most flea markets around here are little more than places to unload Beanie Babies, National Geographic collections, and questionably-obtained car stereos...

Oh, okay, I know what you're talking about now... We can get smaller versions of those at Lowes and Home Depot (we call them Halogen bulbs) and ones that size at the local electrical contractor's store....

Now all I need to do is find an ignition coil or a circuit for a small tesla coil so I can make a "plasma valve" Grin

Best of all with the dead ones is that they're free! People wander back to the hydroponics store with the dead ones in hand so that they get the correct replacement then leave the dead ones behind. Apparently some of them are the size of basketballs! I can't wait for them!

When a cannabis farm a few houses up from my house got raided the other week, they were throwing numerous numbers of those bulbs in the bin lorry.  The police were not too impressed when I asked if I could have one...    Grin


Oh, and ALL the MH lamps contain mercury, they are mercury lamps that are doped with metal salts to change the light spectrum. So wear thick gloves, mask and do it out doors. Also be carefull when you break the outer envelope, it's under a strong vacuum. Wink

They should have been grateful that the globes were going to a good home. Or did they have 'evidence' requirements ?

Thanks for the note on all MH bulbs having mercury - I knew that the one I got did as it's a sodium globe, but I thought that some types didn't. I'm planning on keeping this one sealed and using it as a plasma globe.

Other ones may get opened and cleaned out with 20% sodium thiosulphate to remove the mercury.

Nah, no evidence - the lighting, trays, grow media etc, all got thrown into the bin lorry (aka garbage truck) and crushed with the trash compactor...  Healthy!  Undecided

No need to worry too much about the mercury content, the outer bulb is mostly a vacuum that keeps the heat within the arc tube (the smaller burned / blackened tube in the centre), this keeps up the efficiency of the lamp.  The Inner arc tube is where the mercury and dope salts (all of which are nasty) are located, avoid breaking this, and you won't have problems. There isn't a great deal of mercury, but you should avoid exposure as much as possible. Wink

Be carefull when using that bulb as a plasma ball, the metal supports will emit low levels of soft X-rays, and will slowly contaminate the gas over time. Also you will have to flood the vacuum vessel with Nitrogen, Argon, Helium or some other gas (will require about 5 PSI to work) in order for it to work fully as a plasma ball - otherwise you will just get a small glow from within the small arc tube. The vacuum will not generate any plasma streamers as there is no gas present to ionise into plasma (you will probably get a purple / UV glow however).

Wow.

We need a whole new thread on 'things to do with funky light globes and vacuum tubes that doesn't involve blowing your head off'

I for one would like to be able to either safely power up a big old valve so it glows, or safely drill it out so I can insert LED's.

But I want the soft green glow of glass emitting x-rays, demnit!  Grin

Argon will be the go I think - a nice blue-white and it works up to atmospheric pressure and you can even have som slight impurities. makes it much easier to flush, fill and seal again without having to worry about leakage across the pressure differential to the outside world.

Blowing one's head off ? I think I need to know where you're getting your tubes from!  Cheesy

A globe will be easier to drill out than a valve, as there is more 'stuff' behind the pins on a valve, whereas the globe just has the two electrical contacts. Though I may be biased - I'm more sentimental about valves than globes!

Ever see something at a market that you just have to have, even though you have no idea what you'll do with it?
Spoiler (click to show/hide)

Only cost me a dollar. The seller said that everyone who looked at his table had to pick it up and play with it. The candle holder unscrews too, so I can attach something else if I think of something.
The box was also only a few dollars.

I definitely support the idea of a thread on impressing people with your valves. Although I mostly just light them up the 'normal' way.

Please tell me where to put which wires on what posts on the valve and how much voltage and or amperage to apply to make them glow?

Well, it's one of those things where there are dozens of "standards" to choose from, plus all the ones that vary from the standard! So I'll go through how to work it out.

If you've found the right data sheet for your valve, somewhere near the start of it will be the numbers for the voltage and current for the heater or filament. You'll have to find a power source with the same voltage, +/- 10%, and equal or greater current. If you can't get the right voltage, you can get away with a bit under, the valve will just be dimmer and not as effective in a circuit. Go over and it'll burn out though. As for current, the valve will only pull as much as it needs, however, if the power supply can't supply enough then it may drop it's voltage, pop fuses, overheat, catch fire, etc. Further into the data sheet will be the pin diagram, which will have two pins marked for the heater. To just light it up, it won't matter which way around you connect it to the power supply, nor will it matter if you use AC or DC.

If yours is the FG105 you mentioned earlier, it's going to need a serious power supply. 5 volts and 10 amps! That's 50 watts, so it'll heat up like a mains light globe! The picture on page 3 of the data sheet shows the two pins you need to use, when you're looking at the base, the two marked "Heater Terminal". With that much power needed though, it might be better to hide a normal light globe or LED in it. On the other hand, a couple of them would probably make a good steampunk room heater.  Smiley

For comparison, the valve I was posing with uses 12 volts at 0.45 amps, which is about 5.5 watts. The other valves I play with for my radios and such are smaller and dimmer than that.

So if I get another FG 105 I can use them as headlamps for my steamunk car (as long as I can generate the power required to run them).

Flea markets are a smörgåsbord of tasty gears, springs and goggles... I only wish I had more of a chance to go to some- time is a cruel cruel vice!
I do, however, sport a vast goggle and gear envy of you at this present time!

Anyone going to be out at the Canton First Monday Flea market this upcoming weekend in Texas?

I'm planning on heading out, but would welcome a guide to the 100+ acres of potential
bits, bobs, thingies, whatchamacallits, thingamajigs, etc. I have just acquired a new stash
of parts from Apex and an electronics swap meet this past weekend, and need more parts
to properly slake my mad scientist tinkerings for the next few weeks...

Hey! I couldn't find the *found it at the flea market* thread, which I know is around somewhere, so I'll just post here instead.
I picked up this

lovely thing for comparable pennies at the local antique mall- while I don't own enough jewelry to fill a tenth of it, and I don't much like the mustard interior, it makes a great craft storage bin, and so much prettier than those clear plastic things you buy at craft shops.

Lovely finds! Perhaps you should replace/cover the yellow interior with red velveteen. I think it would be gorgeous with red. Or perhaps green.

Hee hee, I have a couple of similar tins that I rescued from my grandmother's estate sale.

For no obvious reason I'd go for a blue interior. Just seems right to me.

Lovely boxes!
