They arrived today from Russia!
All twelve are in great condition considering that they were made in mid 1980 - they were packaged very well, foam covering some kind of milk-thing-box from Russia which contained more foam wrapping the actual tubes. The tubes are 2 inches high from bottom of the glass to the top, and the characters are 2cm high. Tubes from tubes-store.com/ who still have loads of this type (IN-14) left.
Once I've got some free time I'll turn these into a clock, but first I have to figure out how to generate 170V DC...
Changed coefficient DACs to the same modern part I am using for position and limit: MCP4922. Results are slightly more linear but there is still distortion on long lines that I need to track down.
Displayed on Tektronix 604. There is also overwhelming EMI on these signals that I haven't tracked down/suppressed.
This is what my first generation of irrigation electronics looks
like. I am using a plastic container with clamp on lid to hold the
circuit board and transformer. The small mint tin has a slice in it
so the LEDs can easily be viewed to see just how dry the soil is.
There are four sets of wires running out of the box to the solenoid,
moisture probes, circuit power and transformer power.
Design and build an odometer and speedometer for a model railroad. The distance/speed measuring instrument shall be installed in a separate model railroad car (with its own battery for a power source) and shall display the total distance the train has traveled (in scale miles) and the speed of the train (in scale miles-per-hour). The odometer shall display values from 0.0 to 9.9 scale miles and the speedometer shall display 00 to 99 scale miles-per-hour. The speed display shall be updated about once a second. The measurement shall be accurate to ±1%.
The wheel on the railroad car has a diameter of 33.6 scale inches. A transducer is mounted on the axle that produces four “square” pulses per revolution of the wheel.
We came across an interesting oddity from the realm of consumer electronics: a fake seven-segment LED display. Just for fun, we made our own version too.

A close up of the transmitter section of an M2R, Martlet 2's radio board.
The radio board features a uBlox MAX-M8Q GPS with an LNA+SAW on the input, a Radiometrix MTX2 which can either connect directly to the output or go via a 500mW RF power amplifier, and an isolated connection to a RockBLOCK Iridium satellite modem. It's all powered by an STM32F303CBT7 microcontroller.
Fore more details on the schematics, see: www.cusf.co.uk/2014/07/martlet-2-electronics-schematics/
The PCBs were sponsored by Cambridge Circuit company, thank you! The Radiometrix MTX2s were sponsored by Radiometrix, also a big thank you!
I went for the danger option and added one more nixie, bringing it up to four. Of course I had to have them display 1337.
Looking inside the metal box you can see the deep cycle battery, charge controller, power supply, and the computer with the custom circuit to turn on/off the computer when the sun is out. On the right is the La Crosse weather station.
LEVEL UP!
I now have a nice (working!) circuit. The kit comes with a speaker too, so I was able to test it.
It makes a "ding dong" sound as a Dalek would play it, but well, it's a start ;)

I just found this on the global site of LG Electronics (http://www.lge.com/general/lg_globalsite.jsp). This map links to the separate LG country sites, sorted by regions. Call me a total nerd, but check this out:
Instead of a reunified Germany, I'm seeing a thick border still running between former East Germany and West Germany (I grew up in East Germany, and I can testify that the reunification did happen.....17 years ago); instead of the Czech Republic and Slovakia, I still see the former Czechoslovakia (which ceased to exist more than 14 years ago...); the CIS is not a nation, it's a commonwealth of sovereign states - the LG map shows the former Soviet Union including the three Baltic states (that never belonged to the CIS but are members of the European Union) and Turkmenistan (which withdrew from the Commonwealth of Independent States in 2005). And: Since there's no separate LG country site for Iceland, I'm not going to mention that Iceland actually belongs to Europe and not to North America (Iceland gets tinted, too, when you roll over North America).
It appears that LG doesn't seem to acknowledge the global political situation after 1990. Sweet, sweet Cold War.
I actually kinda like these little bugs on the map if they just weren't of such a scandalous shame for a global company like LG. Nonetheless I tried to send them a mail thru their "Contact Us" mail form to suggest a slight revise of this map (hint, hint!), but their mail form was so badly coded that - after trying three times - I wasn't able to deliver the message to LG.
So let's just leave LG as the Sleeping Beauty and enjoy the good ol' times before the events of 1989.

Electron Memories is an idea that represents my Jewelry and accessories made from recycled electronic components. Memories Electron was born by combining my passion for technology, art and the need to live in a less polluted world. I started taking apart old electronics components that are no longer used or thrown in the street that pollute the soil and underground water.
Researched and dabbled on current trends in jewelry and accessories, it began to emerge creatures and objects of art. So, recycling and combining these old electronics devices where electrons circulates before are now only memories of his travels at the speed of light, these gems were born.
Electron Memories es la idea que representa a mis Joyas y accesorios hechos con componentes electrónicos reciclados. Electron Memories nació combinando la pasión por la tecnología, el arte y la necesidad de vivir en un mundo menos contaminado. Comencé desarmando viejos aparatos electrónicos que ya no usaba o que encontraba en la calle e iban a contaminar la tierra y el agua enterrados como relleno. Reconecté mi pasado artístico de maquetista y se despertó nuevamente el artista que estaba hibernando hasta esta primavera de colores y formas característicos de los variopintos componentes electrónicos.
Investigué e incursioné sobre las tendencias actuales en joyas y accesorios y empezaron a surgir criaturas y objetos de arte.
Así reciclando, combinando y resignificando estos antiguos artilugios de la electrónica por donde antes circulaban electrones y hoy sólo quedan los recuerdos de sus viajes a la velocidad de la luz, nacieron estas joyas. Hernan Bressan.

E depois da tempestade… fazem-se balanços!
O terrível sismo que sacudiu o Japão e cujas consequências ainda estão por determinar em pleno, com algumas das suas centrais nucleares a estarem em sérios ricos de ruptura, afectou todo o mundo.
E, naquilo que pode aparentar ser um egoísmo terrível, também nós, os fotógrafos, fomos afectados, mesmo que neste cantinho do outro lado do mundo.
Veja-se este artigo com data de 16 de Março, retirado da página da Adorama, uma loja on-line especializada em equipamento fotográfico:
UPDATED: Japan Photo Industry Affected by Earthquake and Tsunami
As of this writing, it looks like there were no serious injuries or fatalities among employees of Japanese camera and consumer electronics companies. We will continue to monitor the situation and update this report as needed.
With scores of factories and corporate headquarters around the country, the Japanese photo industry has been severely disrupted by Friday's earthquake, tsunami, and nuclear crisis.
While most companies report that they are still assessing the damage caused by the most powerful quake in Japanese history, it seems that there have been no deaths, and injuries to camera company employees. Structural damage to company facilities vary. Most companies are subject to rolling blackouts that are being imposed by the Japanese power authorities due to the evolving crisis at the nuclear power plants.
The following is an updated run-down of how the quake has effected manufacturers of photographic and other related products.
Epson announced that the Color Imaging Exhibition trade show, which was planned for March 19-21 in Tokyo, has been cancelled due to the crisis. Epson reports that while no casualties were reported at its facilities, one of its factories was hit by a one-meter tsunami, while three other facilities have been temporarily shut due to rolling blackouts as a result of the quake. Two buildings that are within 16km from the Fukushima nuclear plant have sustained some damage and are being shut for now.
Sony was hardest hit. Japan's biggest exporter of consumer electronics, and a growing player in the still photography world, was forced to stop operations at ten factories and two research centers due to quake-related damage and power outages caused by emergencies at nuclear power plants. 1,000 Sony employees reportedly took shelter on the second floor of a nearby chemical products factory.
Nikon has confirmed light injuries to some of its employees but no serious or fatal injuries. Nikon's Sendai factory, which manufactures the D3S, D3X, D700 and F6, has been forced to close due to damage to equipment and buildings. Work at at least three other facilities has been temporarily suspended so the company can assess damage.
Canon has suspended operations at eight factories located in Northern Japan, and reports at least 15 employees were injured. The company said it may move some production to other factories that weren't damaged.
Olympus's photographic division was not affected by the quake, but some emplyees at other locations sustained minor injuries, possibly in the company's endoscopy-related business. Japanese-language press releases indicate that a repair facility is expected to resume operations in 2-4 weeks.
A Sigma employee tweeted that there has been some damage to machinery and the building at Sigma's Aizu factory, but no injuries. Due to the rolling blackouts, Sigma has decided to suspend operations in two of its facilities.
Ricoh reports no injuries. Five of its facilities have stopped operations and four have no set plan to reopen.
Fujifilm reports that its Taiwa-Cho factory, which is located 20 miles from Sendai, was damaged by the quake, but fortunately none of the workers were reported injured. Production of the FinePix X100, which was being done at that factory, has been temporarily stopped and delays can be expected for this highly-anticipated camera. The company says the rest of its operation is not affected.
Hoya Corporation, which owns Pentax, reports that several employees were slightly injured but none seriously. Some production facilities were damaged, although the company is still trying to assess. It isn't known how the camera and lens facilities have been effeccted but due to traffic problems and blackouts, production has been disrupted.
Casio reports no major injuries, and the company is currently trying to ascertain the condition of its facilities. In the meantime, business activities are expected to be disrupted due to rolling blackouts.
In a statement, Tamron reports no structural damage or injuries, but the rolling blackouts and severely curtailed train service have caused the company to close its facilities for at least the next few days.
Panasonic reports minor injuries in one of its northern Japan factories, in Fukushima, where production of Lumix digital cameras has been suspended. The company is evaluating damage and says the long-term effect is still being determined.
Sandisk, whose facilities are 500 miles from the epicenter, appears to have escaped unharmed. The factories were shut immediately after the quake, but resumed opearations by Friday morning.
However, due to possible meltdowns at several of Japan's nuclear reactors, the Japanese government has instituted rolling blackouts, which are disrupting companies even if they were not otherwise affected by the quake or tzunami.
The tsunami has also destroyed many freighter ships, some of which may have been preparing to ship photographic equipment to destinations around the world. This situation is currently being assessed by the companies, but it is likely there will be shortages of some gear as a result.
Epson, Canon, Panasonic, Sony, Ricoh and Nikon have all reported that they have donated hundreds of millions of Yen to the relief effort and are contributing in other tactical ways to help survivors.
This report was based on information published by TIPA, Amateur Photographer, Reuters, and statements from several manufacturers.
The car is heavy on its springs as I bring a load of old computers to the local electronics recycling day. The total was 2 monitors, 2 printers, and 2 external HD arrays and about 12 computers of various vintages back to a 486.
