I work with high schoolers and their teachers, and I often come across questions about how to get started with physical computing. This post is meant to compare some of the most well-known platforms. To begin, understand that the space is broadly separated into microcontrollers and single-board computers, with different strengths and weaknesses. Microcontrollers (MCUs) Microcontrollers are basic, general-purpose processors with limited capabilities compared to single board computers (SBCs). They offer slower processing speeds, smaller storage capacity, and fewer communication options. Unlike SBCs, which run full operating systems, microcontrollers typically execute only one program at a time. Despite these limitations, microcontrollers have several advantages. They are generally more affordable than SBCs, and their simpler architecture makes it easier to understand and control their behavior. Additionally, microcontrollers can begin executing their programs almost immediately after pow...
I've been mulling it over for weeks, and I decided that a new laptop really would help my endeavors this semester. My old laptop is a bit slow at this point, but I could live with the dated technology. What really prompted me were the bulk and weight of the machine, and the fact that it has a 2 minute battery life. It's impractical to try and use that laptop very often, since I'm forced to sit near an outlet and take a few extra minutes for setup and tear-down. So today I finally took the plunge. Armed with some leftover student loan money, I headed to Best Buy. I had already shopped around and picked out the machine, so the transaction was fairly quick. I am the proud new owner of an HP Pavilion dv2415nr . It's fairly small and light, and looks great with their Wave pinstripe design. It's got Windows Vista, an AMD Turion dual-core processor, comes with 1GB of RAM (I'll probably upgrade that posthaste), and built-in NVIDIA GeForce graphics! Not to mention the in...
In the past week or so, I've been putting in applications everywhere, because frankly, my financial situation is worse than bad. And it may be paying off, just maybe. I had another interview yesterday with Best Buy, this time for Computer Sales. The interview was pleasant and went well enough, but I'm not hopeful. I subtley pried into my chances of getting the job, and it sounds like the manager is looking for something else. For one thing, I don't have much sales experience and computers are inherently difficult to sell. But the biggest thing is my schedule. It's the Best Buy closest to the CU campus, so naturally, all the college students apply there. That means the employers are flooded with people who can work nights and weekends, precisely when I'd be able to work. He said he'd pass my application around to the other departments, but frankly there's better jobs out there, at companies that haven't turned me down twice. However, a beacon of light sho...
