RSA SecurID Teardown

I did a teardown of an RSA SecurID many years ago (you can see that post here). In that teardown, it was an older generation (SD600) of the RSA SecurID. In this post, let’s take a look at what’s inside the newer SID700 series RSA SecurID token. A short video of the teardown is included towards the end. Continue reading ‘RSA SecurID Teardown’ »

Keithley 706 RTC Upgrade – How to Make Any Clock More Accurate

The builtin real-time clock (RTC) in my Keithley 706 works rather nicely as a clock in my lab when the scanner is not in use. The 7-segment displays are big and clear and they are two dedicated displays for the seconds which comes in quite handy. However the main drawback of this auxiliary clock functionality is that, well, it is not very accurate. It is rather annoying when I need to adjust the clock every couple of days to make sure it remains correct. Continue reading ‘Keithley 706 RTC Upgrade – How to Make Any Clock More Accurate’ »

I2C Data Logger Using ATmega328p and DS3232 – I

There is a popular data logger shield out there designed for Arduino using a DS1307 real time clock chip. And that design makes data logging extremely easy if an Arduino board is used. Continue reading ‘I2C Data Logger Using ATmega328p and DS3232 – I’ »

A Clock/Stop Watch Based on BQ3287

Over the past couple of weeks, I have been experimenting with BQ3287, a real time clock module from Taxes Instruments. My ultimate goal was to eventually create a full fledged control platform based on this RTC module (more on this later). But first and foremost, I would like to explore its capabilities as an accurate time keeper. Continue reading ‘A Clock/Stop Watch Based on BQ3287’ »
