Miscellaneous
This topic is nothing new and there are already quite a few good articles on the web on this. But I thought I would try to provide a more comprehensive view on this issue and give a few concrete examples…
Last week, I received two of the demo boards from Renesas. One is a YRPBRL78G13 and the other is a RPBRX62N. The RL78/G13 promotional board features a 64 pin R5F100LEA 16-bit microcontroller, which has 64K flash ROM, 4K data flash…
AVnet has so far been my most favorite parts supplier and I have used it quite a few times. Not only do they offer a rather comprehensive catalog, their prices are quite competitive as well and their shipping and handling…
Breathing in fumes while soldering is not good for your health, so it is recommended that you have a fume extractor in your workshop. A typical fume extractor sucks in air and passes the fumes through layers of active carbon.…
I had almost forgotten about the experiment I started late last year using the data logger I built to log the temperature and humidity values in my basement lab for an entire year. The logger worked well during the initial…
Alexa is a great tool for gathering your website’s statistics. Using its traffic rank moving average, you can see how your content affects your site’s popularity over time.
The power finally came back early this morning. So from last Saturday till today, we have been without power for almost ten days. Well things could have been a lot worse. Thankfully my generator had been working great without a…
The Halloween nor’easter knocked out power and internet service last Saturday. Even though I have a backup generator, the internet outage caused my site to go dark for the past few days (well almost a whole week).
Many of the modern chips such as MEMS accelerometers and gyroscopes only come in surface mount versions and many of them come in fine pitch LGA or QFN packaging. This has created a significant challenge for people who just wanted…
Since I do not have a DSLR camera, taking photos for my projects under normal room lighting can be quite challenging. When flash is used, the pictures often turn out to be none-uniformly lit and some components reflect quite a…
Most of the multimeters do not offer resistance measurement in the milliohm range. In most meters a typically Ohm range has an accuracy of 0.1 ohm and is too coarse for measuring small resistance. Of course, some of the high-end…
One of my computers has been unstable for quite some time now. It had been crashing and freezing up once a while in the past, but it has become noticeably worse in recent months and sometimes the computer would crash…
One of my RSA SecureID tokens had recently expired, so I decided to do a teardown to see what is inside. While there was one such teardowns posted on EETimes a few years ago, I thought it would still be…
Apress was kind enough to send me a copy of their recently released book “Arduino Robotics” a few weeks ago (ISBN13: 978-1-4302-3183-7, 628 Pages. Publication Date: July 18, 2011). So I thought I would read through and do a quick…
As I mentioned a couple of weeks ago, I had been having some issues with my wireless connection at home. My suspicion was that this is an inherent issue with either 2701HG-B hardware or firmware.
