I promised earlier this week to write about another use of Stability Test. The other use of Stability Test is for underclocking your CPU for better performance, undervolting it for better battery life, or both.
While a good number of people do both to their Nook Color, I can’t get mine to run for any length of time without crashing when I do either. Oddly enough, my Nook Color will pass Stability Test for 12 hours at 1.1 GHz, but then when I go to use it, it freezes up.
Mine was a refurb unit, so I may not have gotten the best chip in the batch. It’s entirely possible that it’s a refurb because some other enthusiast got it, tried to overclock it and couldn’t, then exchanged it for another, and then B&N tested and resold it as a refurb. But I find using Go Launcher EX makes life at 800 MHz tolerable on the machine anyway, especially when I use the apps for the web sites I visit most frequently, rather than trying to use a web browser.
I take my Nook Color with me enough that I wanted a case for it, but nothing too fancy, seeing as I’d rather spend money on hardware than on accessories.
Most retail stores carry cases for 7-inch tablets and e-readers, but they’re a high-margin item, often selling for $20 and up, which is 25% of what I paid for the device. I looked on Amazon, of course, where I found multiple cases for less than $10, but found conflicting reports as to whether any given case actually fit the Nook Color. Read more
If you’re looking for the best glue for paper models, you’ve come to the right place. To build a paper model that lasts, use a pH-neutral PVA bookbinder’s glue. My wife, who has a master’s degree in art education, specifically recommended Books by Hand PVA Adhesive. Although it looks and smells and feels like regular white glue, I find it does a better job of not warping the paper and not bubbling. And for longevity’s sake, you want something that doesn’t change the pH balance of your paper. Books by Hand glue is pH neutral.
I started building model structures with Books by Hand glue in 2004. Those miniature buildings still look like I built them yesterday. Read more
The last two netbook vendors standing, Acer and Asus, have both announced they’ve produced their last netbook. So they’re joining the Playstation 2 in the land of the digital dinosaurs, though I suspect more people will miss the 12-year-old game console than the netbook. The Guardian has an analysis, but basically they blame the emergence of tablets, and the increased cost of producing netbooks with Windows.
I gave Go Launcher Ex a whirl on my hacked Nook Color-turned-tablet. The promise was that it’s faster and smoother than ADW Launcher, the default program launcher that comes with Cyanogenmod. Unlike some promises, it was true. It’s fast, smooth, polished, and customizable.
I was a little apprehensive at first–how does one go about changing something so fundamental as the program launcher–but it was easy.
I always burn in my computers. But how do you burn-in an Android?
Here’s what burn-in means, if you’re unaware. When you first buy a computer, the very best thing you can do for it is leave it on for 24 hours nonstop, preferably doing something that’s reasonably hard work. That practice is called burning in a computer. If there’s anything at all wrong with it, there’s a very good chance it will come up in that initial 24 hour period. I’ve been doing that for more than 20 years, and of all the computers I’ve owned in that timeframe–and it’s an army of them, believe me–I’ve only had one machine fail prematurely. One.
The practice works.
So what about a tablet or a smartphone?
Electrodroid is an Android app designed for electronics hobbyists, but it has uses for model railroaders too. Its LED calculator is invaluable when using LEDs to light buildings, cars, locomotive cabs or headlights, or for other projects. Knowing the input voltage, you can then determine what resistors to use to protect the LED.
The voltage drop calculator is useful too, if less obvious. Read more
One thing I’m seeing in the predictions-for-2013 columns is that mobile malware is going to increase this year. While I can’t be certain it’s going to happen, all of the ingredients are there. The only thing stopping it is motive.
I’m familiar with Avast antivirus on Android. It’s nice. Whenever I download an app from the Google Play store, it scans it, and if it finds something it doesn’t like, it intervenes. Read more
