New Life for Nixie Tubes

The Nixie Tube was, in a more enlightened era, the standard method for electonically displaying numbers, letters or other symbols prior to the introduction of the LED. Those of you of a certain age will remember that all calculators once utilized Nixies.

According to Wikipedia:

The Nixie display was developed by a small vacuum tube manufacturer called Haydu Brothers Laboratories, and introduced in 1954 by Burroughs Corporation, who purchased Haydu and owned the name Nixie as a trademark. The name Nixie was derived by Burroughs from "NIX I", an abbreviation of "Numeric Indicator eXperimental No. 1"[4]. Similar devices that functioned in the same way were patented in the 1920s, and the first mass-produced display tubes were introduced in the late 1930s by National Union Co. and Telefunken. However, their construction was cruder, and they failed to find many applications until digital electronics reached a suitable level of development in the 1950s.

Burroughs even had another Haydu tube that could operate as a digital counter and directly drive a Nixie tube for display. This was called a "Trochotron", in later form known as the "Beam-X Switch" counter tube; another name was "magnetron beam-switching tube", referring to their similarity to a cavity magnetron. Trochotrons were used in the UNIVAC 1101 computer, as well as in clocks and frequency counters...

Citing dissatisfaction with the aesthetics of modern digital displays and a nostalgic fondness for the styling of obsolete technology, significant numbers of electronics enthusiasts in recent years have shown interest in reviving nixies. Unsold tubes that have been sitting in warehouses for decades are being brought out and used, the most common application being in homemade digital clocks. This is somewhat ironic, since during their heyday, nixies were generally considered too expensive for use in mass-market consumer goods such as clocks. This recent surge in demand has caused prices to increase significantly, particularly for large tubes. The largest type known to be in the hands of collectors, the Rodan CD-47/GR-414 (220 mm [8.7 in.] tall), have been sold for hundreds of dollars apiece, but these are extremely rare and only found in a few areas of the world by persistent and fortunate seekers.

David Forbes and his homebrew electronics company, Cathode Corner, often have marvelous examples of Nixie-powered clocks and wristwatches for sale on their site and on eBay.

Duck Hunting in a Donkey Suit

From Scientific American Supplement, December 12, 1891:

"The wild duck is a shy bird, apt to spread his wings and change his quarters when a noble sportsman is seen approaching his habitation with a fowling piece. You have heard of the ass who put on a lion's skin, and wandered out into the wilderness and brayed. I have elaborated a device of equal ingenuity and more convincing realism. It is my habit during the duck-shooting season to put on the skin of a Blondin donkey and so roam among the sedges bordering on the lakes where wild ducks most do congregate. I have cut a hole in the face to see through, and other holes in the legs to put my hands through."

Sarina Brewer's Taxidermy Art

Taxidermy artist Sarina Brewer offers a variety of strange homemade creatures for sale on eBay and on her website, which states:

None of the animals used in Sarina’s work were killed for the purpose of using them in her art. All animal components are recycled. She utilizes salvaged roadkill and discarded livestock, as well as the many animals that are donated to her. Donated animals are often casualties of the pet trade, destroyed nuisance animals and pests, or animals that died of natural causes. A very strict "waste not, want not" policy is adhered to in her studio - virtually every part of the animal is recycled in some manner.

This artist has a deep respect and appreciation for animals and the natural world. She is fascinated with the circle of life and intrigued with how different cultures honor their dead and deal with death.

Sarina is a self-proclaimed science nerd who incorporates her past formal art education with her passion for biology and the bizarre. Her childhood preoccupation with cryptozoology and anomalies of nature manifest themselves in her outlandish reveries of fur and flesh and every peculiar artifact she creates.

"Know, My Lord, There is a Dampish Cave".

Catclaw Theatre Company's puppetry production of The Birth of Merlin, attributed to William Shakespeare and William Rowley in a 1662 quarto, promises to be a pip, a corker, a humdinger. It'll be held in a creepy old run-down warehouse in the East Flatbush district of Brooklyn, and will be veritably oozing with mythic resonance. As with Toulouse-inations, you'll see more than a few anachronisms in the course of the proceedings, and all included with some degree of deliberation. Steampunk fans will definitely find grist for their mill here, despite the medieval setting...

Halloween

Samhain, or "Summer's End", marked the end of the harvest in Celtic tradition; the end of the "lighter half" of the year and beginning of the "darker half". Samhain begins at sunset tonight and continues all day tomorrow until sunset.

It was once believed that the border between this world and The Otherworld became at its thinnest on Samhain, that it opened a portal of opportunity to enter the Otherworld, and for Otherworldly entities to enter our realm. The resultant celebration took on a sort of Festival of the Dead feeling.

The Gaelic festival became associated with the Christian All Saints Day and All Souls Day, and later got woven into the secular customs now connected with Halloween.


Beginning in the Middle Ages, the custom of "Souling" became popular, in which poor people (both children and adults) would go door-to-door begging for food on All Saints Day. Something called "Soul Cakes" were made and distributed to the beggars, each cake eaten supposedly representing a soul being freed from Purgatory. Although some would claim an unbroken line of tradition between Souling and Trick-or-treating, there is actually a considerable gap in the historical record. According to Wikipedia:

Ruth Edna Kelley, in her 1919 history of the holiday, The Book of Hallowe'en, makes no mention of ritual begging in the chapter "Hallowe'en in America." Kelley lived in Lynn, Massachusetts, a town with about 4,500 Irish immigrants, 1,900 English immigrants, and 700 Scottish immigrants in 1920. The thousands of Halloween postcards produced between the turn of the 20th century and the 1920s commonly show children but do not depict trick-or-treating. The editor of a collection of over 3,000 vintage Halloween postcards writes:

"There are cards which mention the custom [of trick-or-treating] or show children in costumes at the doors, but as far as we can tell they were printed later than the 1920s and more than likely even the 1930s. Tricksters of various sorts are shown on the early postcards, but not the means of appeasing them."

The earliest reference to Trick-or-Treating occurs in a 1927 Canadian newspaper article that speaks of it as if it is a brand-new fad theretofore unknown.


Attempting to contact The Spirit World via wooden alphanumeric Ouija Boards was a popular Halloween party diversion during the Victorian Era. The "divination by planchette" phenomena is one that is real and is verified, despite skepticism by the public. This skepticism was exacerbated by the marketing of the board as a child's toy in the mid-20th century. By itself, the board does nothing. It is solely for the guide of the Spiritualist medium to conduct the seance using it and the planchette as a tool.

Quest for Fire

There's a whole multiverse (literally!) of cool old cigarette lighters out there, all of which are perfectly suitable for time-transcending troublemakers such as ourselves. The above one, cleverly concealed in a pocketwatch housing, was found on Pewtersmith's flickr. A particular favorite is the World War I military lighters fashioned out of spent .30-caliber cartridge casings. Here's one, spotted on Zenbeer's flickr:


The first cigarette lighters were called Döbereiner's Lamps, invented in Germany by Johann Wolfgang Döbereiner in 1823. These worked by way of a charmingly Rube Goldberg sequence of events: zinc metal reacts with sulfuric acid in a small glass jar, producing hydrogen gas which is released when a valve is opened. This jet of hydrogen bursts into flame when ignited by platinum.


Lighters are swell, and I own zillions of 'em, from antiques to mid-century Zippos to cheesy plastic contemporaries - but what I really prefer to light my stogies with is good old-old-old-fashioned wooden matches. Kitchen matches in particular are dripping with mythic resonance, and dammit, they smell great. (I am a card-carrying Philluminist and love all things matchy.)


The Diamond Match Company has nice old-timey matches that can be found in any supermarket, but they also make hard-to-find "strike anywhere matches", which is how all old matches actually used to be. Once upon a time, the white phosphorus on matchheads was so sensitive you could rub a match against almost any surface and make it go off, and the sudden poof of flame could be quite powerful and flashy compared to the wimpy matches of the 21st century.

Ever wondered why people in the movies were managing to strike matches in weird places? In Stalag 17, for example, William Holden lights a match against someone's razor-stubbled chin; and the high flammability of those good old-timey matches was also a key part of that film's plot, with an American soldier devising a time-bomb by nestling a lit cigarette amongst a pack of matches. When the cig burned down to all those volatile white phosphorus matchheads, KABOOM!

In Miller's Crossing, Tom contemptuously lights a match off a policeman's chest, which is believable since the film takes place during prohibition. Not so much with The Breakfast Club, though: Bender lights a match off his teeth, and then lights one off his shoe, which isn't possible with modern matches unless he's gone to the trouble to cut the striking board off a pack of matches and glue it to the edge of his sole. (Hmmm... that's not a bad idea actually...)

A zillion cinematic tough guys in old noir films would conceal a strike-anywhere match in their hand, and with a one-handed flip of the wrist, ignite it against their thumbnail and bring it to their cig, making it appear to modern tv-watchers that they somehow magically just conjured up fire out of nowhere.


Swan Vestas, pictured above, are a British strike-anywhere match said to be more powerful and more like the old classic formula than Diamond's. I'd love to try these out, doubly so for the fact that Victorian burlesque drag-king Vesta Tilley took her showbiz name from the term "Vesta" (a 19th century brand of matches that was so popular, it ended up becoming a generic term).

Starks Marble

The Starks Building (now the Hertz-Starks Building), built in 1913, sports some truly amazing white-and-gray marble on every wall of every floor. Even the hallway drinking fountains are made of marble.

The Baghdad Batteries

In 1936, in the village of Khuyut Rabbou'a (near Baghdad) in Iraq, archaeologists discovered some peculiar ancient vessels, each containing an iron bar and a cylinder of rolled-up copper sheeting.

They languished in a museum's storage for two years, until Wilhelm König, director of the National Museum of Iraq, found them and became fascinated. In 1940, he published a paper speculating that they may have been galvanic batteries, capable of electroplating gold onto silver objects.

The Copper sheeting and iron rod in the Baghdad batteries form an electrochemical couple, so that an electrical voltage will be produced in the presence of an electrolyte. Lemon juice, grape juice, vinegar and other acidic substances are generally thought to have been used in the Baghdad batteries.

Wikipedia says:

"The Discovery Channel program MythBusters determined that it was indeed plausible for ancient people to have used the Baghdad Battery for electroplating or electrostimulation. On MythBusters' 29th episode (which aired on March 23, 2005), ten hand-made terracotta jars were fitted to act as batteries. Lemon juice was chosen as the electrolyte to activate the electrochemical reaction between the copper and iron. (Oddly enough, it was discovered that a single lemon produced more voltage than one of the batteries when using copper and zinc.) However, the batteries which they reproduced did not produce a substantial amount of energy and had to be connected in series in order to achieve a 4 V potential drop and test the theories.

The show's research staff proposed three possible uses: electroplating, medical pain relief (through acupuncture), and religious experience. It was discovered that when linked in series the cells indeed had sufficient power to electroplate a small token. For acupuncture, the batteries produced a "random" pulse that could be felt through the needles; however, it began to produce a painful burning sensation when the batteries were grounded to two needles at once. For the religious experience aspect of the batteries, a replica of the Ark of the Covenant was constructed, complete with two cherubim. Instead of linking the cherubim's golden wings to the low power batteries, an electric fence generator was connected. When touched, the wings produced a strong feeling of tightness in the chest. Although the batteries themselves had not been used, it was surmised that, due to the apparent lack of knowledge of electricity, any form of electrical sensation from them could equate to the divine presence in the eyes of ancient people."

Regarding the observation that using a lemon actually worked better than lemon juice, it may well be that the creators of the batteries actually used several fruits connected in a series, which itself may have also been immersed in lemon juice - electric kool-aid, indeed. Some other item may have been used as a electrolyte which has not yet been considered.

The Rods of Ra site suggests a connection between the Baghdad batteries and mysterious Egyptian ornamental rods such as those found belonging to Pharaoh Pepi II. Another company, Egyptian Healing Rods also sells modern replicas.

The Antikythera mechanism

In 1900, divers searching for sea sponges off the coast of Antikythera Island (northwest of Crete) made a startling discovery. The hull of an ancient ship was found, and it was filled with beautiful statues of marble and bronze.

An expedition was made to salvage everything on board the ship, with special focus on the works of art. It wasn't until a couple of years later that archaeologists got around to examining what they considered to be lesser artifacts. Then they realized that one of them contained cog wheels.

Controversy erupted over the find, which turned what we thought we knew about world history on its ear. Mainstream science, faced with something that made them wrong, did what they've always done: they ignored the anomaly.

It wasn't until 1958 that someone finally took the Antikythera mechanism seriously. Dr. Derek de Solla Price from Yale University mounted a full-scale investigation and restoration of the device. Originally, the device seems to have been built around 150 B.C. in a wooden box with inscriptions that contained an extremely accurate astronomical calendar. Inside it were twenty cog wheels and, even more stunning, differential gears (neither of which had been previously thought to exist at that time). Price wrote:

"Nothing like this instrument is preserved elsewhere. Nothiing comparable is known from any ancient scientific text or literary allusion. On the contrary, from all we know of science and technology in the Hellenistic Age, we should have felt that such a device could not exist."


Price also speculated that the item may have once been on public display on the isle of Rhodes. Wikipedia says:

The island was known for its displays of mechanical engineering, particularly automata, which apparently were a specialty of the Rhodians. Pindar, one of the nine lyric poets of ancient Greece, said this of Rhodes in his seventh Olympic Ode:

"The animated figures stand
Adorning every public street
And seem to breathe in stone, or
Move their marble feet."

On 31 July 2008, a paper providing further details about the mechanism was published in Nature (Nature Vol 454, Issue 7204, July 31, 2008). In this paper, among other revelations, it is demonstrated that the mechanism also contained a dial divided into four parts, and demonstrating a four-year cycle through four segments of one year each, which is thought to be a means of describing which of the games (such as the ancient Olympics) that took place in two and four-year cycles were to take place in any given year.

A working reconstruction of the Antikythera mechanism has been built (see image above) for the National Archaeological Museum of Athens, by Robert J. Deroski.

The Falcon Heene Incident

What a day.

I'm sitting around the house trying to get up the oomph to go out in the cold when suddenly, there's breaking news on MSNBC: a helicopter is in hot pursuit of a giant flying-saucer-shaped balloon that accidentally came untethered and took off 10,000 feet in the air with a 6-year-old boy inadvertently aboard. Usually I manage to let tragic news stories wash off me like bourbon off a duck's back, but something about this one really got to me. The horror of the poor child, being that young and trapped inside a balloon that high up, being buffeted around by the winds, probably to eventually crash in the Colorado mountains... it made me sick to think about it.


So we're watching the story unfold, glued to our seats, in sympathy for this little boy trapped inside a balloon hurtling through the air, when the horrific announcement is made that that they think he may have actually fallen out of the balloon to his death somewhere along the way.

Sure enough, when the balloon finally makes its descent into a field, there's no boy inside and the National Guard is mobilized for a massive search for young Falcon Heene's body. A sickening end to a sad afternoon, seemingly.


But then, after all of that, it turns out the kid is alive and well and has been hiding in a box in the attic all afternoon. As of this writing no one's determined what the backstory is to this bizarre drama. And I haven't heard conclusively yet whether this was intended as some sort of weather-balloon science project (the Heene family are well-known storm chasers) or whether it really is an experimental aircraft as the media have speculated.


I've been a bit miffed at the coverage of the incident on both CNN and MSNBC, which I kept flipping back and forth between. Both came dangerously close to openly ridiculing the Heene family over their alleged belief in extraterrestrials, over their storm chasing hobby and their interest in science, and their having taken part in the reality show Wife Swap earlier this year. Apparently having an interest in science, weather, and UFOs brands you as a kook in Rick Sanchez' eyes. Me, I think this Heene family sound like my kind of people...

The Bee Smoker

The modern single-handheld bee smoker was invented in 1875 by Moses Quinby, the first commercial beekeeper in the USA. Quinby's device, with a bellows attached to a tin burner, vastly improved previous methods of blowing smoke onto beehives, a practice that has gone on since the ancient Egyptian civilizations, and probably even earlier.

According to Wikipedia:

The fact that smoke calms bees has been known since ancient times; however, the scientific explanation was unknown until the 20th century and is still not fully understood. Smoke masks alarm pheromones (which include various chemicals, e.g., isopentyl acetate) that are released by guard bees or bees that are injured during a beekeeper's inspection. The smoke creates an opportunity for the beekeeper to open the beehive and work while the colony's defensive response is interrupted. In addition, smoke initiates a feeding response in anticipation of possible hive abandonment due to fire. When a bee consumes honey the bee's abdomen distends, making it difficult to make the necessary flexes to sting. (The latter has always been the primary explanation of the smoker's effect, since this behavior of bees is easily observable.)

Smoke is of limited use with a swarm, partly because swarms have no honey stores to feed on. It is usually not needed, either, since swarms tend to be less defensive as they have no home to defend, and a fresh swarm will have fed well at the hive it left behind.

Remind me to get around to inventing a musical bee smoker that plays like a miniature squeeze box/concertina when the bellows are pressed.

(Pictured above: a Steampunk bee smoker from Dreadnought Designs)

Potatoes as Batteries

We've all seen the novelty gag of potato clocks, but what happens when you martial the combined power of five hundred pounds of spuds? From the website of performance artist Amos Latteier:

"I built a potato battery out of 500 pounds of potatoes. It powered a small sound system. With the help of the Red 76 crew I installed the battery and sound system in the back of a U-Haul truck and drove it around town inviting people to enter the truck and take a listen.

Batteries work by allowing electrons to pass from one electrode to another. In this case the potato provides phosphoric acid, which enables a chemical reaction causing electrons flow from copper to zinc. The zinc came from galvanized nails and copper came from small pieces of copper. You don't have to use potatoes; any acidic medium such as citrus fruit will work. I chose potatoes because they are traditional and cheap.

Each potato generates about 0.5 volts and 0.2 milliamperes. I connected groups of potatoes together in series to increase voltage and then connected these groups together in parallel to increase amperage. The entire 500 lb battery generated around 5 volts and 4 milliamperes.

Don't eat potatoes after using them for a battery."
