My Electronics Workstation includes computer Diagnostics and Analysis capabilities, which work alongside with my collection of Vintage 1950′s / 60′s reconditioned testing and evaluation equipment. My so called obsolete equipment includes a (factory built) HeathKit Model # 0-12 Oscilloscope which is a bit antiquated, However this device has been modified and serves me well. I also use a Tektronix 465 scope and the computer scope for comparative purposes. My Hewlett Packard collection includes the 410B, 400D voltmeters, a 5512A electronic frequency counter and a 202C low frequency oscillator. I have three vacuum tube testers. My primary unit is a Sencore MU140, which has been painstakingly reconditioned. The unit was removed from it’s original briefcase enclosure and was mounted into a slide out drawer under my workbench. My secondary unit is a custom built computer assisted tube analyzer and the third unit is a B&K 747 for continuity and comparison, providing me with backup in the event of a failure. A note of possible interest: when I removed the Sencore’s control panel from it’s case, I found a Lawrence Livermore National Laboratory (NASA) Service Technician’s punch list sheet with notes, plus additional Sencore documents in a plastic envelope mounted on the inside bottom of the briefcase enclosure which was a fascinating find. I also have a few other interesting devices tucked away. Some other essential pieces of equipment I have besides a few extra multimeters is a handmade multi outlet isolated & regulated power supply, several variable DC power supplies and a variable metered autotransformer. This equipment is just a chain of readily available components on the power supply end of an electronics workstation, assuring an outcome that results in the best possible performance from your equipment and the tasks at hand. However a typical power supply and protection setup like this is not fool proof and can be vulnerable and unreliable under certain conditions, making it necessary at times to use battery operated (standalone) equipment in conjunction with your AC equipment while performing certain multi point tests to avoid misleading readings. All and all, I have enough confidence to use my vintage test equipment without computer assistance, weather it’s a checkup, test and repair job or even on a new build. Some of the devices mentioned but not seen in this photo are kept in an easily movable autonomous roll out equipment rack under the workbench.

Note: this photo was published as an illustration in an Aug 2009 Squidoo blog titled "Discount Laptop Batteries." Ironically, the blog is about batteries for Dell laptops, but this guy is clearly using a Mac Powerbook. Later on, the photo was also published in a Sep 27, 2010 blog titled "Laptop Reviews:Laptops: the Age of Communication." It was also published in an Oct 4, 2010 blog titled "Toasted skin syndrome: warm laptops may cause skin damage."

Moving into 2011, the photo was published in a blog titled "Buy Best Laptop & desktop Computers for College Students." It was also published in a May 5, 2011 blog titled "How to Choose Best Laptop for College Students."

Moving into 2012, the photo was published in a Feb 14, 2012 blog titled "Is This a Good Computer?"


Back in the spring of this year (2009), I decided to pay a visit to Washington Square Park (pictures of which are available here), having earlier stumbled upon some photos I had taken there 40 years earlier, in the spring of 1969 (photos of which are included in this album). I was surprised to see that the park was undergoing massive renovation, and that the fountain was closed off; but some construction signs promised that it would be open once again in the summer …

So this past weekend, I decided to venture back to the park once again. The renovation was indeed finished; the fountain was operating again, and the warm, sunny weather had attracted throngs of New Yorkers and tourists to spend a pleasant afternoon engaged in all sorts of activities — much of which involved splashing around in the water. But there was also juggling and chess and scrabble, guitar-playing folk-singers and a violinist, two different jazz bands, and an energetic quartet singing old 1950s doo-wop ballads.

I spotted tourists and visitors from Japan, Italy, Scandinavia, and various parts of the U.S. People were sunbathing on various patches of grass around the edge of the park. There were children, students, lovers, families, and old hippies; and there were half a dozen dogs, at least a few of which enjoyed the opportunity to splash in the pool. There was an ice-cream cart and a hot dog stand, and if the park was anything like the old days, there probably at least a few places to buy drugs of every conceivable kind. For those who might have wondered what this place really was like in the "old days," there was a cheerful old guy (named Robert Fogelnest, from what I could find on the Internet) peddling copies of a book titled The Streets of Greenwich Village.

All in all, there was something for just about everyone. If you’ve got an afternoon free while it’s still summer here in New York City, I highly recommend a stroll through Washington Square Park. Remember: summer won’t last forever…

Eric asked me awhile ago to make a video for any of his songs… So, tonight, I was just sitting around, bored after having completed most of my homework. And I’ve been feeling especially creatively restless lately, so I started messing around with photo booth on my computer because I had left the battery for my camera at home. What eventually resulted was this video! I’m happy to say that Eric likes it very much! Which is most important to me!

This is a frame from a video. You can watch it on Vimeo.
