Back to the real world. I have re-immersed myself in the learning required to build a little automated, web connected weather station. I have been learning a lot about working with the Arduino (proto boards built around the Atmel ATMega 328 microcontroller), and have added some goodies around connecting sensors, working first with a 1 wire humidity and temperature sensor, and soon to come some...
I learnt early on that you get what you pay for, and web hosting is no different than any other good or service. There was a time when $3 – $6 a month got you a pretty good deal as the explosion in hosting services was happening, but as with all services that are shared, the only way the economics work out is to over subscribe. The same happens with internet service (if everybody downloads...
Why is it so hard to find a decent web host? Way back in 2009, I began blogging on wordpress.com, and by the end of 2009, I was hooked. I took the plunge, and signed up with MediaTemple hosting, a pretty slick operation that had a quite good product offering, with their “gridservers”. That worked well, and apart from some shared Mysql server bog downs, it was a pain free time. The few...
This project builds upon the flashing LED of the first project. If you were motivated, you could change the frequency of the flashing, by adjusting a constant in the program, a “delay” value that was used to turn on and off the power to the LED. This circuit instead brings in the concept of analog versus digital circuits, something that is worth explaining. In the digital realm, a signal is “on”...
The Sparkfun Inventors Kit arrived, and I have to admit that it was better than I expected. Packaged in a nice box, it has plenty of goodies, and projects to play with. There are enough parts that I am sure I can go well beyond the scripted projects. Last night, I did the (really minor) assembly, but didn’t dive in. However, this morning, I dove right in, and did the first project. As one would...
My main computer since 2013, has been a rocking MacBook Air. It is the first generation of the system based on the Haswell chipset, and it has been awesome. It came with Mountain Lion (10.8), and has been upgraded thrice now, recently to El Capitan. When I got it, one of the huge benefits was the battery life. The data sheet said 12 hours, and it easily beat that. I often went several days...
Earlier this week, I got a Facebook message from my sister. Their iMac was behaving poorly, lots of spin-y beachballs (the “I’m thinking” on the Mac OS-X), so I asked the usual questions. What model iMac is it? (from the about and system report) How much memory is there? How big is the disk, and how much is used (from DiskUtil)? All the standard things, but the DiskUtil reported...
Back in 2010, I was looking for a note taking solution. I had a taste of the Microsoft solution, OneNote, but being a “Mac” person, and the fact that OneNote wasn’t cross platform, and I went looking for a solution. The obvious choice at the time was Evernote. Cross platform, and while it wasn’t as flexible and convenient as OneNote, it was serviceable. Over the years, the...
My old MacBook Pro has seen better days. For far too long it has been my “main” home computer. All my photos, music and videos were stored there. However, with iTunes Match (and now the new streaming service), and the moving of all my photos out from under Aperture to Photos (grrrr) and more importantly, to Adobe Lightroom, there isn’t much need for a massive system anymore...
My iPad that I bought in 2011, is nearing the end. Not that it isn’t still functional, but at near 4 years old, it is finally showing its age. I shouldn’t complain, nearly 4 years out of any tech gadget is a remarkable feat, and a testament to Apple’s quality and standards. My iPad, a generation 2 unit, is showing its age. When iOS 7 came out I dithered about upgrading, knowing...
