Single Board Computers- The Arduino YUN Review



Hackers and hobbyists have used the arduino for a diverse number of projects and have made it a very popular. Its simple to use and easy to program. For people who have a slightly ‘more’ requirement, ARM based single boards came into the market. Initially the ARM boards were tougher to build and program and costlier to make. In order to fully exploit the power of a 32-bit processor, the Linux Kernel was ported to the fanless ARM systems making the Single Board Computers. The OS was stored on either an SD Card or an EEPROM. This new class of boards had the familiar OS system of a regular PC and the digital and analog outputs of the arduino but at a slightly higher cost. Additionally they had varying performance but they started to add something more- peripherals! Keyboard, then Ethernet, then Bluetooth and Wifi- the list goes on. In this article we discuss the Arduino YUN and what exactly it is. Continue reading “Single Board Computers- The Arduino YUN Review”

The Raspberry Pi Power Analysis featuring the Tektronix Scope


I am waiting for my stuff to get delivered which are basically parts and parts. One of features of my design is that the raspberry pi center piece is portable, ie it can be moved from one location of the house to the other. For this I needed to add a battery backup which was shown in my previous posts. In my recent experiments, I found that the Raspberry Pi was rebooting unexpectedly. It turns out that one of the connectors was defective. Still this left me with the question that if I am using a battery, how long will my system stay afloat without power? Hence I setup a little experiment to measure the power consumed by the Raspberry Pi and the results were quite unexpected.

CapSense MBR3 Evaluation Kit – Review

CapSense MBR3 with Arduino Nano


A lot of projects and products involve a user interface which is buttons and switches and knobs. The cost of industry grade panel push buttons is really high and it gets worse as the buttons become environment proof. With that said, Capacitive Touch sensing has come in to replace mechanical buttons and the Cypress CapSense MBR3 does exactly that. The solution is a single chip auto calibration system which does most things for you. Most Capacitive Touch sensing solutions offered need a lot of technical expertise but Cypress claims that their solution is just easier to use. I will be reviewing the developer side of the solution as opposed to the kit itself. Continue reading “CapSense MBR3 Evaluation Kit – Review”

TI Fuel Tank BoosterPack & MSP430F5529 Launchpad – Review

TI Fuel Booster PackDisclamer: I respect the work put in my every design engineer. I understand that they did the best job that they could and will learn over time. This text is in no way telling anyone that they did a bad job. I’m just suggesting changes which may or may not be practical or even usefu

I started out very excited and looking at the specs, the big picture was very nice. When I started working with the kit, things really did not go as planned and this review is more of a rant than anything. Ti Should take notes and if they are really interested in the hobby market, they should take my suggestions into consideration.
Lets begin. Continue reading “TI Fuel Tank BoosterPack & MSP430F5529 Launchpad – Review”

Review: PiFace Control and Design

Box Contents


The raspberry pi is a cheap and highly customizable single board computer with gpio pins which can be used to control electronics. There are many ways to expand the functionality of the pi and a company called piface is in the business of making add on boards to do just that. One of the boards they sell is the piface display and control which is marketed by element 14 and we had a chance to get our hands on one. Continue reading “Review: PiFace Control and Design”

Unboxing the MSP430 eZ430-RF2500


I really wanted to experiment with some wireless sensor networks, so I went looking about a year back. One of the Texas Instruments Reps was gracious enough to lend me his demo kit and well I wanted to show it off. There is a new kit available from TI nowadays, but don’t know if I will be getting one for Christmas this year.
Here is the eZ430-RF2500.
