My sony p200 had a faulty flash - I found some cheap spare parts for the p200 on ebay and a service manual - so i went about replacing it myself. it wasnt easy! it was like working on laptop computers only smaller.

I've now got it so that when the time changes, the clock display fades from the old time to the new time over the course of about 1/3 of a second. It's a tough effect to photograph - here you can see the seconds* ticking over from 59 to 00; in both cases the 59 is very dim and the incoming 00 much brighter. I shot it from two different angles to show the face-on view and obliquely so you could see how the numbers are stacked in the tube.

 

Trust me - in person, this effect looks really, really cool and now I know why some nixie-clock-building geeks make such a big deal out of it.

 

A big part of my design decision to make this nixie clock microcontroller-based was that it would let me do nifty display trickery like this easily. Nixie clocks don't need to use computer-type guts; a very popular circuitry design for them uses only discrete logic chips ("popcorn"). Popcorn is a lot like circuitry legos - you can get chips that do all sorts of little jobs like counting from 0 to 9, or for converting a binary number to a decimal one. There are 4 of the latter on this clock's driver board.

 

The popcorn version has the advantages that a) the builder doesn't need to know any programming or own any equipment for burning microcontrollers and b) it might last longer; microcontrollers' flash memory may "forget" their programming after a mere decade or so, while discrete logic is hardwired to do what it does. However, I'm not sure if the nixies themselves will outlive the microcontrollers' memory retention.

 

Microcontroller-based clocks, apart from fancy display stuff, can also be easily interfaced with very accurate, battery-backed real time clock chips (like I did) or even to GPS or radio circuitry that automatically synchronizes them to the official atom-clock time. Nifty!

 

*But wait! You say. Seconds are showing on a four-tube clock? Why yes. I borrowed a trick from the ancient LED-wristwatch days and have a button you can press to show the seconds on the rightmost (minute) tubes while the leftmost (hour) tubes are blank. I hadn't really planned on this, but it's just too much fun to watch the seconds tick by. Hypnotic, even.

The Solenoidal Tracker at RHIC (STAR) is a detector which specializes in tracking the thousands of particles produced by each ion collision at RHIC. Weighing 1,200 tons and as large as a house, STAR is a massive detector. It is used to search for signatures of the form of matter that RHIC was designed to create: the quark-gluon plasma. It is also used to investigate the behavior of matter at high energy densities by making measurements over a large area.

These displays are all new for my Walmart.

 

My local Walmart recently under went a slight remodel in adding new signage as well as a slight rearrangement in aisles for some departments. I figured I'd take some photos of all the new sights. Pictures of the old arrangements can be found in the same album.

This series of images will guide you through modifying an HS-311 servo to give continuous rotation in either direction, with a degree of speed control.

The modification is non-reversible, but these servos are cheap as chips so this shouldn't be a big worry.

A vintage Leeds & Northrup decade resistance box, model 4776. These were used as resistor substitutions in instrument calibration and as teaching tools in countless physics labs. Although the model 4776 was sold as a working instrument rather than a standard, its accuracy was within one part per thousand (as good as a standard). This item was a gift from a university. Despite research, I have not been able to find the exact date of production, although it was mentioned in a physics paper published in 1955, and was advertised at a price of $35 (works out to $374.82 in 2014!!!) in a 1948 publication.

Some old electric circuit board photographed against the light. Certain similarities to a city map, hmmm? AFAIK this TTL graveyard is either from a 1960s/1970s plotter or from a diskette drive unit.

Erie, PA. April 2014.

Yahoo! today upped the ante in consumer-centric mobile design by launching a new version of the company’s mobile home page in early beta at the Consumer Electronics Show (CES) 2008.

 

Today’s announcement further extends Yahoo!’s mobile leadership by providing consumers with a visually-stunning and easy to navigate interface for the most visited mobile site in the U.S. (M:Metrics, October 2007).

 

By visiting beta.m.yahoo.com from select mobile phone browsers, consumers will experience an open and customizable home page where users can personalize their mobile experience like never before, drawing content from the Yahoo! network and leading Web properties from around the Internet.

 

Yahoo!’s new mobile home page was designed to quickly become the essential starting point for the mobile Internet. Incorporating the best “home page” elements from pioneering PC portals such as My Yahoo! and the Yahoo.com Front Page, it embraces a dynamic, open and highly personalized approach.

 

“Today we set the standard for what consumers are demanding from the mobile Internet. As the definitive starting point for mobile users around the world, our new home page is beautifully-designed and optimized for the mobile device,” said Marco Boerries, executive vice president, Connected Life, Yahoo!. “As we’ve done before, we’ve set an incredibly high bar for the industry with our innovation and ability to deliver prolific services to millions of global mobile users, helping them discover what a truly compelling mobile Internet experience should be like.”

 

Key features include:

 

Personal Vitality and Status Updates - Provide an at-a-glance update of what’s new since the last visit – including recent emails, Flickr photos from your friends, upcoming calendar appointments and status of Yahoo!

 

Messenger contacts – all without moving away from the home screen or logging into a separate application.

 

Customizable Content - Offers a collection of mobile content modules known as Yahoo! Snippets that provide previews of the user’s favorite content from any source - news headlines, weather conditions, and more – whatever the user wants.

 

Quick Links - Customizable links at the bottom of the page, providing fast access to the Yahoo! services and other sites across the Internet that consumers use the most. Consumers can easily add and remove quick links as they desire.

 

oneSearch - Mobile search designed to give instant answers and relevant information by understanding the user’s query intent and optimizing the results accordingly. Recently upgraded to include content from Wikipedia and Yahoo! Answers, as well as airline flight status information.

Damn.

 

I got some 'splainin' to do.

 

It was listed as Buy iy Now doe $69, but I put in an offer of $40.

 

A 1960-ish Japanese SLR, with an intriguingly obscure lens - a Simlar 2.8 50mm.

 

So it joins the pile.

 

DeJur apparently was a brand that was applied to a variety of cameras starting in the late 1940s.

 

This camera might be the same as the Topcon PR II, which sold with a very "simlar" Topcor 2.8 50mm as the standard lens. A 4 element, 3 groups Tessar design.

 

Did I pay too much?
