It is cold again Project 365(3) Day 216
Computer Batteries

Image by Keith Williamson
Pam and I seem to be going though one of those periods that you have when a number of challenges loom up to face you.

First it was the battery on the car that died, then I had problems with the installation of programs on my new computer, I had a hair on the sensor of my best camera, one of my UPS expired, the fence at the back was making its way into the garden below and finally (I hope) the new air conditioning unit stopped blowing cold air.

This air conditioning unit worked fine when it was first installed. The air in the room was nicely chilled and it was taking out a decent quantity of water each day. Then gradually it chilled less and less and the room still felt muggy an hour or so after the unit was switched on.

Nothing else for it, call the shop and get someone out to look at it so that is what we did yesterday. This morning, first thing, the technicians arrived and confirmed my suspicions that somehow all the gas had escaped from inside. After taking this outside unit off the wall, it was an easy job to locate the gas joint that was leaking, correct that, fill the unit back up with gas, and check that all was well with a manometer.

Result, the unit is working 100% again, the air is nicely chilled and the water bottle outside was half full after just two hours of operation.

Now back to that garden fence!

Apple Magic Trackpad (Review)

24

This is a follow up to my hands on video. The new Magic Trackpad is essentially a MacBook trackpad for the desktop. The multi-touch surface supports a full set of gestures, allowing users to scroll, pinch, click, rotate, and swipe. The trackpad is a wireless Bluetooth device that utilizes two AA batteries. Interesting, Apple has released its own separate rechargeable batteries and battery charger, which includes six NiMH batteries for your MagicPad, Magic Mouse, and wireless keyboard.

Powerbook – iBook comparisson

Powerbook – iBook comparisson
Laptop Batteries

Image by mac steve
After two years with my iBook I thought it was time to upgrade. Both machines shown above cost roughly 1.5k Euros (incl. memory upgrade, airport and bluetooth and tax). And while the PB is obviously speedier and has a far superior keyboard it is questionable if this was a good buying decision.

The Powerbook gets considerably hotter than the iBook, has less battery life and wifi reception is close to unusable in many locations. The iBook G3 is super quiet. The fan goes on only after 1hr of playing DVD whereas the fan in the powerbook goes on after five minutes looking at webpages. Apart from writing mail the fan is almost always on.
The iBook fabrication quality unfortunately got worse with each incarnation and the one seen here has already the crappy plastic (opaque white). More recent iBooks have a better keyboard but poor trackpads.

This powerbook has an okay trackpad and the display has probably the standard of iBooks of late 2001 (which mean it is better than my previous iBook).
The powerbook is a thing of beauty. Even today the quality of the case is marvelous, but that doesn’t help when you stay offline due to poor reception.

Maybe I should get a life instead of looking for a useable laptop.

The Nadi Temple – A Feast for the Eyes

I have little text today, because I have a tonne of images to show to you. This morning I took a short bus ride to the Nadi Temple, as it is commonly called. My friend, Heather, suggested it to me, though her directions left something to be desired. Jump on a bus and you will probably be there in ten minutes:

Don’t dally at the Baby Face Nite Club, or they won’t let you in at the temple.

In fact, there are some things you should know before visiting. Prepare to leave your shoes at the gate. Do not eat any meat for breakfast. The man at the gate will ask you. Wear modest clothing, long trousers for men and a shirt that has at least short sleeves. I was dressed in my usual short-shorts and a tank top. This evoked a frown and a warning not to enter the temple itself, but, having paid the F.50 to enter the grounds and take pictures, I was otherwise treated politely. I’ll save my breath by showing you a little summary casually ripped from a travel web site:
In 1994 this Hindu temple moved from beside the flood-prone Nadi River to the southern end of town where an evocative three-tower complex was finely created over a ten-year period by eight specialist craftsmen brought from India.

The Dravidian temple is dedicated to the deity Murugan whose statue, specially carved in India, is housed within the twelve-metre-high main pyramidal vimanam with a rectangular roof. The two towers at the rear of the temple with colourful domed shaped roofs are dedicated to Ganesh and Shiva.
Since I was not allowed to enter the temple, I decided to do my best from outside. Fortunately, the opportunities are superb:

My goal, from the first moment, was to try to grab shots that others might miss. If I have a "secret formula" this is it. These images have all been sent up to my server at 2,000 pixels, so if you click on any of them, you will get some good detail.

As I walk around I am constantly looking for amusing compositions:

The one above is crazy, but it works for me.

Another thing which I decided to do is to Photoshop without mercy. I wanted to get that "postcard" look which is just short of fake:

Fortunately, the light and sky were playing my game.

Even shadowed areas came through brilliantly:

The Canon G11 was strutting its stuff today. I have no complaints about any frame it gave me.

Walking around the temple, you can find plenty of treasure in the odd angles of the structure:

I could have stayed there all morning, but there were worshippers moving about and I was disgustingly under-dressed.

The details of the temple can keep you snapping until your battery runs down. Here’s an example:

And another:

And one more:

I have a dozen more in the folder, but you get the idea.

What I can’t show you properly, since I could not go in, are the astonishing paintings on the ceiling of the entire temple. Here is one that I could, with a little standing yoga, get a shot of:

It’s a bit distorted, but so was I while I was taking it. It took some fancy Photoshop tweaking to get it reasonably rectangular.

That’s about it for me. My shoulders are getting sore from using the laptop on the bar here. It’s the only place where I can get both a wireless connection and power. No beer for me until I figure out what’s come unwired in my head.

My latest 2013 workbench incarnation. A tube mic waiting for components and two small amp chassis hangin’ around amongst my vintage hardware along with my computer testing and analysis equipment,

My Electronics Workstation includes computer Diagnostics and Analysis capabilities, which work alongside with my collection of Vintage 1950′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 my workbench.

Recent equipment includes an additional Sencore MU140 tube tester, a Hewlett Packard 339A Disortion Analyzer, DDS signal generator, Owon Handheld 60Mhz oscilloscope with advanced multi-functions and a Heath Zenith variable isolated AC Power Supply, plus some assorted specialty hand tools.

"Please don’t knock vintage testing and analysis equipment. It helped to put 12 Humans on the surface of the moon."
