This meeting was also used as a showcase for a variety of tech toys. One of the exhibits was a Sears “Endurable” flashlight, about the diameter of a standard double D cell light, but only half as long. With substantial rubber end caps, this light uses 4 AA cells, with illumination provided by 5 super bright LEDs. Several members own this unit, and while pleased with the apparent ruggedness and features of the light, all agreed that the pushbutton switch, which cycles through “Spot” “Flood” and “Both” settings, requires excessive force to operate.
Micro Center’s latest flyer offers a three and a half digit multi-meter (DVM850BL) by Velleman Components for $10. When first introduced, these hand held meters, a replacement for the typical VOM (volt ohm meter) would cost approximately $250. I built my first such instrument from a Heathkit about twenty years ago, and it cost about $100. The Velleman meter, about 2 3/4 inches wide and 5 ½ inches high, includes a “touch and hold” function, and back light. Ranges: 5 - DC volts from 200mv to 600V; 2 - AC volts 600 & 200; 5 - DC amps from 200ma to 10A; 5 ohms from 200 to 2 megohms; plus audible continuity; diode polarity / forward voltage drop; Transistor hFE (gain) for PNP and NPN transistors. Includes yellow rubber “shock / drop” shell with stand.
Several years ago I bought a similar digital meter from Sears (Craftsman 82140) in a special package (34-82146) that included a “fat pen” sized Voltage Detector (92174) for $19.95 in a sale I’ve seen several times since. The Sears meter doesn’t have the transistor gain range, including instead 1.5 and 9 volt battery ranges, which tests with a load on the cell / battery in question. A set of alligator clip adapters, which plug on to test lead tips (Radio Shack 270-354A, $2) make a handy addition to any meter.
Another useful gadget for household electrical projects is a Circuit Breaker Identifier (Radio Shack 22-113, $30). This is comprised of two parts, a signal transmitter that plugs into a receptacle (or lamp socket with an adapter) and a receiver that has a LED lamp and piezo buzzer that will indicate which breaker the transmitter is plugged into.
For those trying to identify or troubleshoot telephone wiring, a KP100 Tone and Probe Kit by Test-Um, Inc. was displayed. This consists of a tone set that injects a warble tone signal or “talk battery” on a pair of wires. The companion tracer probe is used to identify the correct conductors by picking up and amplifying the test tone when the probe tip is near the desired wire pair. About $90, available at Micro Center, along with a variety of LAN and telecommunications test equipment.
The same set of ads included an offer of Scansoft’s Paperport 9 for $30 after rebates. This is a great program, in my opinion, for scanning things and turning them into PDF files that can be viewed on the web. It also includes a module that allows “printing to PDF” - so anything you send to a printer can be turned into a PDF file.
Months ago, I responded to one of Chuck Robert’s articles and demos on system backup by buying a housing for a USB backup drive and USB add-in card. I later discovered that I’d failed to scrutinize the box closely enough, and the card wasn’t a USB 2.0 spec. Both my desktop systems had USB 1.1 ports.
The installation of the cards went reasonably smoothly, although I had to change slots in my backup system for the card to be recognized. I also found that when I installed the USB 2 card in my primary system that the card slightly pulled out of the PCI motherboard slot, as I tightened the card mounting screw. During upgrades to other systems, I found similar problems with cards not fitting properly, and wound up doing surgery on the mounting bracket with a Dremel Mototool. Granted, the system case could be the problem, if the plane of the motherboard and the back of the case aren’t at a ninety degree angle. However, I’m inclined to suspect poor quality control in production of the cards and their mounting brackets.
Worthwhile Laptop Accessory
I recently “invested” in a Toshiba laptop - it appeared in a CompUSA 20th Anniversary ad with a special series of rebates in one Friday’s POST. Rebates included $100 from Toshiba, $150 from CompUSA, plus another $100 from CompUSA to price match the same computer offered by Circuit City in the Sunday ads. Then, there was the $187 in free merchandise I was able to select as part of the Anniversary Sale. That provided a Belkin Wireless Router / 4 port switch, and a wireless LAN card.
Meeting Demonstrations
At the February general meeting, I’ll be talking about various publications of Sandhills Publishing, including Smart Computing, PC Today, and Computer Power User, and a series of computer related references and guides. Attendees will receive copies of Smart Computing, and there will be door prizes, including a year’s magazine subscription, a five volume reference library, and other guides and reference publications. A special program for NCTCUG members will also be introduced. Members purchasing subscriptions of two or three years in length will receive a reference guide as a bonus. For every five subscriptions purchased, NCTCUG will receive a subscription gift certificate for door prize purposes. More details will be available soon on the web site, or contact me for information.|
Robert W. MacFarlane ![]() In remembrance of Bob, a dozen NCTCUG members have contributed a total of $180 to the Meals on Wheels Program of the Arlington Presbyterian Church. During the funeral service for Bob, his minister noted that, when she’d visited Bob during a hospital stay several years before, his first words were to “tell the Meals on Wheels coordinator I won’t be able to drive this week!” We hope our contributions will help carry on this work our friend felt so important. |
The advent of the recent “Code Orange” security update seemed to call for additional preparation around the old homestead. Fairfax County was testy about parking an Abrams tank at the curb in front of the house, so I decided to invest in comm equipment instead. As many of us found out a few months ago when Isabel blew through Virginia, we are mightily dependent on the good old electric power companies. Your GameBoy is guaranteed to have eaten or worn down your last batteries that fit in the portable radio when the lights dim and flicker out.
So, what’s the solution for those times with no battery availability? Picking up on the BayGen Freeplay radio of the early ‘90s, Grundig offers the FR200 AM/FM Shortwave radio, complete with crank for dynamo operation. Turn the crank handle for 90 seconds to charge the internal NI-MH battery pack, and you’ve got about an hour’s worth of playing time at reasonable volume. The radio includes a little flashlight bulb (and a spare!), so you can pick your way around furniture - once you find the radio, of course.
