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 on how to filter out the electrical noise from motors in your circuits.

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 and 4K RAM. The RX62N contains a R5F562N8BDFP 32-bit microcontroller, which has 512K ROM, 32K data flash and 96K RAM

One of the biggest advantages of FRAM (or FeRAM, Ferroelectric RAM) over EEPROM is that FRAM has a much higher write speed and typically can operate at bus speed. This means that no delay instructions are needed when performing write operations, which greatly reduces coding complexity and increases the overall throughput.

MMA8453Q is a rather inexpensive accelerometer. It is significantly cheaper than many other 3-axis accelerometers (such as the popular LIS3LV02DL) and yet it offers a reasonably high 10 bits resolution and packs a rich set of features that simplifies designs and programming in many different applications.

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 practices are excellent — sometimes to the extreme.

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. While effective, it is probably an overkill unless you spend most of your day in your workshop.

A while back, I created an Arduino plugin for NetBeans so that I could use the full-fledged NetBeans IDE for all my Arduino projects. The approach I took was using the NetBeans project sample module method. Under the hood though, it is nothing more than a makefile and an source file template.

Last time I did a pretty thorough review of the X-TRONIC 4040 hot air rework/soldering station and shared my own experience with it. Overall, it is a very good entry level rework station. I have been using it intensely for the last week or so and it is holding up extremely well. Now let us take look at what is inside.

I have used quite a few professional SMD rework stations before, but those professional grade ones tend to be quite pricey. So when I decided to get a hot air rework station for my own personal use, I settled on the cheaply priced X-TRONIC 4040 hot air rework/soldering station combo. In this blog post, I will do a detailed review of this rework station and walk you through some of my observations. In the next time I will do a review of its internal construction.

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 trial run, but having it run continuously for a whole year is another story.

I have built quite a few (1,2,3) temperature measurement circuits in the past, but none of those has remote sensing capability. So I decided to make a wireless temperature sensor so that temperature measurements can be made anywhere within the range of the transmitter and the receiver.

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 glitch for the last week and half.

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).

I received my STM32F4-Discovery evaluation board last week. So I setup the required development environments and did a quick test.
