Nixies were introduced when vacuum tube hardware automatically provided the high voltage they require. These days, circuitry typically runs on five volts or less, so finding the +170V or so for Nixie anodes can be a bit of a challenge. Here are three transformer based ways to obtain that high voltage in line-powered semiconductor-based devices.

Nuts and Volts is a bimonthly American magazine for the hands-on hobbyist, design engineer, technician, and experimenter. It has been published by T&L Publications since 1980 and leans heavily toward microcontroller and digital electronics projects. The magazine is based in Corona, California.[1]

The primary issue of Nuts and Volts was available in 1980. At first it was intended as newsprint, all advertising magazine that was typically distributed for free. The magazine was published on a monthly basis.[2] Over the next few years, the monthly continued to grow in distribution and publicity. However, not much changed until February 1992 when Nuts and Volts changed to a tabloid format and began to make the shift to a more magazine-like format. Editorial features were added along with monthly columns and projects for electronic DIYers. Since then, Nuts and Volts has matured into one of the most well-liked and pertinent magazines for the electronics hobbyist in the United States of America. With the January 2003 issue, Nuts and Volts was reformatted from a tabloid size to a standard magazine size. Nuts and Volts now averages about 100 pages per issue and is printed on gloss paper in full color. As of September 2008, Nuts and Volts reported an average monthly circulation of 44,737 copies. In May 2018, the magazine switched to a bimonthly publication schedule.[3]

We've been placing print ads for about a year now in the magazines that we think you read (Make, Circuit Cellar, Servo, and Nuts and Volts). We realized that there are probably a large group of people who haven't gotten the benefit of seeing these great pictures in print, so we posted the images for the general public. If you know of another good publication we should be advertising in, let us know!

Elektor is a very popular European magazine that has been around for a long time. It just started publishing in the USA though. Both the European and the USA edition would be great candidates for your ads.

Resistor-transistor logic, then diode logic, etc - eventually we got to learn basic digital ICs (74xx series). Over time, we also learned about LEDs, etc. Most of us read our books, some of us subscribed to magazines (I've kept up a Nuts and Volts subscription for 20 years; I've subscribed to Servo Magazine since getting the pre-Servo robotics insert mag with my N&V), we also read books, etc.

So take your time; pick up a copy of the Grob book I mentioned above if you're really serious about electronics. Get some subscriptions to N&V and Servo Magazines (Make is "ok", but they don't go into as deep on theory and such like N&V and Servo does). Look into back issues (online if you can find them with Google Books) of old Popular Electronics and Radio-Electronics magazines. Continue to ask questions as well.

Ohm told us a long time ago that when you have a device that has voltage across it and current running through it, it will get hot. He went so far as to say that the heat (measured in watts) would be the product of voltage and current. In better mathematical form, Ohms law for power can be expressed as P = E x I where P is power in watts, E is electromotive force in volts, and I is current in amperes.

Lets take the example of our old friend the LM317 voltage regulator. The input will be a regular old aircraft battery bus that can rise to 14.4 volts when being charged. We want to regulate this voltage to 5 volts to run some digital logic, and we measure that this digital logic is drawing 750 mA of current.

Scholarly and trade journals, magazines, technical reports, conference proceedings, and govt. publications. Subjects include aeronautics and aerospace engineering, applied physics, AI, robotics, astrophysics, computer applications and programming.

Exhibits of nuts, nut literature, trees, grafting methods, a buddingtool, etc., were received and shown from nineteen differentcontributors. A detailed account of these has been published and is onfile.

In this connection, I will have to say, however, that I neglected tobring my correspondence relating to the nomenclature of Juglansmandshurica. I can say a word that the committee may wish to use. For along while, I have been trying to trace the origin of the name Juglansmandshurica. It is applied to two different nuts. The one described inthe United States government bulletin is the nut originally described byMaxim as Juglans mandshurica more than thirty years ago. Thatnomenclature has priority for two reasons: first, because of the date,and in the second place, because of the recognized standing of Maxim asa botanist. The Yokohama Nursery Company has been sending out a verydifferent nut which they call Juglans mandshurica, evidently of therace of Juglans regia. The Juglans mandshurica of the governmentbulletin is like the butternut, the Juglans mandshurica of the nurserycompanies is evidently a race of Juglans regia. I have conferred withDoctor Britton, Sargent, and other authorities, and we have never beenable to trace the name given to this walnut of the Juglans regia type,Juglans mandshurica, until by accident I happened to get word from theYokohama Nursery Company to the effect that they had made up that namein the office a few years ago, not knowing[Pg 13] that a previous Juglansmandshurica existed and had been named by Maxim. So that traces therodent to its hole. The name Juglans mandshurica by Maxim is theproper name for the worthless butternut-like nut from China. De Candollenamed the valuable walnut that has been sent out by the Yokohama NurseryCompany Juglans regia sinensis. So both of these nuts have beenpreviously named, and by authority.

Five of the hickories: H. pecan, H. Texana, H. minima, H.myristicaeformis, and H. aquatica belong to the open-bud group, whilethe rest belong to the scale-bud group. The winter buds of the open-budgroup resemble the winter buds of the walnuts in a general way, and inartificial hybridization experiments I seem to note a close relationshipbetween the open-bud hickories and the walnuts.

There is no more promising work for the horticulturist than cross[Pg 15]inghickories with walnuts, and crossing hickories with each other. Fivehundred years from now we shall probably find extensive orchards of suchhybrids occupying thousands of acres of land which is now practicallyworthless. The hickories are to furnish a substantial part of the foodsupply of the world in the years to come. At the present time wildhickories held most highly in esteem are: H. pecan, H. ovata, H.Carolinae-septentrionalis, and H. laciniosa. Several other kinds haveedible kernels, sometimes of excellent character, but not readilyobtained except by boys and squirrels, whose time is not valuable. Inthis group we have H. alba, H. glabra, H. villosa, H. glabra pallida, H.glabra odorata, H. glabra microcarpa, H. Mexicana, H. Buckleyi, and H.myristicaeformis. In another group of hickories with temptingly thinshells and plump kernels, we have a bitter or astringent pellicle of thekernel. This group contains H. Texana, H. minima, and H. aquatica.Sometimes in the bitter group we find individual trees with edible nuts,and it is not unlikely that some of them represent hybrids in which thebitter and astringent qualities have been recessive.

One of the main obstacles to propagation of hickories has depended uponthe fact that nuts did not come true to parent type from seed. This isovercome by budding or grafting, and we can now multiply the progenyfrom any one desirable plant indefinitely. In the South grafting isnearly as successful as budding, but in the North budding seems to bethe better method for propagation. The chief difficulty in grafting orbudding the hickories is due to slow formation of callus and ofgranulation processes which carry on repair of wounds.

The propagation of trees from a desirable individual plant can beaccomplished also by transplanting roots. A hickory root dug from theground, divested of small rootlets, cut into segments a foot or more inlength, and set perpendicularly in sand with half an inch protruding,will throw out shoots from adventitious buds. In my experimental workwith hickory roots, in covered jars, surrounded by wet moss, but withthe entire root reached by light, adventitious buds have started alongthe entire length of the root, and we may find this an economical wayfor root propagation, dividing up sprouting roots into small segments.The chief objection to this method of propagation as compared withbudding is the length of time required for seedling trees to come intobearing, propagation from roots probably requiring the same length oftime as propagation from seed, whereas by budding or grafting thebearing period begins very much earlier. Forty-six years ago Mr. J. W.Kerr of Denton, Maryland, planted three pecks of large shagbark hickorynuts, but of the progeny only about twenty were satisfactory, most ofthe trees bearing inferior nuts. These trees required from thirteen toeighteen years to come into bearing, and young trees that Mr. Kerrpurchased from nurseries and planted were twenty-five years old beforethey began to bear. Others who have planted shagbark hickories andpecans state that nearly twenty years are required for the trees to comeinto bearing on an average. When budded or grafted the pecan sometimescomes into bearing in two years, and frequently in four years. We mayanticipate that other hickories will act analogously.

The hickories prefer rich, well drained soil for best development ofnuts, and an abundance of moisture, provided the land is well drained.Many of the hickories, however, are so adaptable to various soils thatthey often thrive in lands that are sandy, and dry, and almost barren.In the latter case, they have to maintain an enormous root system forfeeding purposes, and this is detrimental to good bearing qualities. Themocker-nut, pignut, and hairy hickory, perhaps adapt themselves best tosandy soils. This feature may make them valuable species for plantingwhen one has no other soil, because the stocks can be used for graftingbetter kinds. e24fc04721
