It’s been almost a year since I started my discharge test of the Kentli PH5 Li-ion AA battery, and the battery has lost almost 40% of its capacity due to self-discharge.
Kentli PH5 Voltage (Jun 18 2015 – May 29, 2016)
Kentli PH5 State of Charge (Jun 18 2015 – May 29 2016)
The discharge curve has gotten a lot less… linear since the last time I posted a self-discharge update. The battery is down to 62% state-of-charge, and its voltage has dropped down to 3.89 volts. Still, there’s a lot of time left until this battery reaches empty… but when?
I’m no statistician, but doing a linear extrapolation in Excel gives an approximate end date of January 2018, and the SLOPE() function in Excel gives me an average drop of 0.111%/day. Of course, this can easily change over the course of this test, but only time will tell…
2016 has flown by with considerable speed as of late – it’s already near the end of March the beginning of April, and I haven’t published a single blog post…
“So, what’s up with you?”
I will admit it – much of the radio silence on my blog stems from my own complacency. My desk/work area had accumulated vast amounts of detritus, many of them being half-done projects that never reached completion and years of deprecated audio equipment that wasted a good 1/3 of my entire desktop area – not to mention plenty of dust. All of this resulted in a workspace that made typing for any extended period of time quite uncomfortable; even attempting to play computer games had the risk of me breaking something, or vice versa.
This school year has been going pretty well. I’ve left Electronics Engineering and have started Broadcast Systems Technology; it’s essentially a mix of basic electronics, IT, radio and audio/video equipment. With that sort of fresh start (and extra credits that allowed me to free up considerable amounts of time), I’ve begun to clean up my area – a process that started in January and only recently has progressed to a point where I could “re-format” my desk space to maximize its usability.
Now that I’ve finally cleaned up my workspace, I can finally type in comfort again. I have several draft posts in various stages of completion, and I want to be able to get them finished up and published sometime soon (of course, no hard deadlines are set as I likely wouldn’t meet them anyway).
Domains & Advertisement Monetization
Over the years that I’ve been running this blog, my viewership has increased to levels I would have never anticipated when I first started writing blog posts on here, and I’d like to thank all of my readers for that.
As of late, I’ve averaged around 10,000 views per month, with significant peaks now and then. Because I’m currently running on the WordPress with a non-Premium account, most of my pages have advertisements in them that I have no control over. I can pay a hefty fee to go Premium and remove the advertisements completely, but I would like to at least to be able to get something out of those advertisements.
After looking online about WordAds, I’ve found out that I would need to register a proper domain name for this blog, which makes total sense – why bother putting branding on a .wordpress.com subdomain? Because of this requirement, I need to register my own domain… but what should I choose?
The whole issue of picking a domain for registration was one reason that I’ve been putting it off for so long. I could go with a domain with my name on it (literally!) in a similar vein as Gough Lui’s blog(disclaimer: I have absolutely no affiliation with him; I’m simply using his domain as an example… but on that note, his content is definitely worth checking out!), or perhaps simply remove the .wordpress portion of my blog’s URL.
With that decision in mind, then comes the choice of whom to register with. WordPress has their own service that ties seamlessly with their blogging platform, but incurs a higher cost than other providers. Alternatively, I can choose a lower-cost provider, but then I would need to manually connect that domain with WordPress’ platform. Admittedly, I have little experience when it comes to Web hosting; it’s why I started my blog on WordPress in the first place, and also one of the largest factors in my reluctance to register a domain for it in the first place.

Either way, domain registration and advertisement controls are decisions that can be put aside until later. On that note, if I were to register a domain, what do you think would be a good choice? Leave your choice in the poll below!
The WordPress.com stats helper monkeys prepared a 2015 annual report for this blog.
Here’s an excerpt:
The Louvre Museum has 8.5 million visitors per year. This blog was viewed about 120,000 times in 2015. If it were an exhibit at the Louvre Museum, it would take about 5 days for that many people to see it.
After finally reinstalling Windows on my main PC (the smart card components in the old install were trashed), I dusted off the old smart card reader and started looking into smart card-based logon options again.
Windows logon screen using a smart card
After finding a way to forceconvince the installer for EIDAuthenticate, a program that lets you use smart cards to log on a Windows computer without the use of domains and Active Directory, to run on Windows 7 Professional (Microsoft DreamSpark only lets me obtain the Professional editions of Windows), I found a program called NFC Connector Light that lets you use any NFC-compatible smart card as a means of authentication.
Virtual smart card with certificate installed
NFC Connector Light links the unique identifier in an NFC-based smart card to create a virtual smart card on the local computer (no data is stored in the card itself), and that virtual card can be used like a real smart card within Windows. When paired with EIDAuthenticate, logging on is as simple as placing the smart card on the NFC reader and entering a PIN. This is especially useful when you set the Windows smart card policy to lock the computer when the card is removed (and it feels kind of cool to be able to lock your computer simply by taking your card off the reader).
Whew, I’ve been working on this version for quite a while. With the helpful feedback of many people that have tried my software, I’ve made a large number of improvements to the software; of course, there are plenty of features that aren’t implemented yet, but are being worked on.
More information about how this utility works can be found here.
Aw what, it’s October already? So much for having another blog post in September…
But anyway, “more months, more data!™”
Kentli PH5 Voltage (Jun 18 2015 – Oct 1 2015)
Kentli PH5 State of Charge (Jun 18 2015 – Oct 1 2015)
The voltage of the PH5 has dropped down to 4.093 volts as of today (October 1st, 2015), and its State of Charge is now 93%. There’s just enough data to guess the discharge rate of the PH5: with the currently logged data, the PH5 self discharges at approximately 0.103%/day. At this rate, the cell should last years before finally reaching zero. Looks like this will be a very, very long term test…
(At least that would give me more time to procrastinate write blog posts.)
