Introduction This is my final blog about my journey into the world of supercapacitors. I must say, it has been quite some journey and I have thoroughly enjoyed this design challenge. In my introductory blog , I had noted that one of my primary goals…

Hello everyone. This is my final blog as part of Experimenting with Supercapacitors design challenge. In this blog I will publish details and results of all my experiments which I did using Cornell Dubilier supercapacitors in last 6 weeks. In this blog…

Introduction The experience with supercapacitors has been very positive. Ever since I received the supercapacitor kit from Cornell Dubilier, I have been playing with these devices trying to figure out how to use them for an energy harvesting project…

Intro This experimenting with supercapacitors design challenge was a great way to learn about supercapacitors, everything from how they are made and what handling precautions are needed to their performance and what applications they are good for. After…

Preface In this design challenge, due to generosity of our sponsors: Cornel Dubilier and Element14, we had a chance of experimenting with supercapacitors of various families manufactured by CDE. Those included: six parts (of three different capacitance…

Six weeks ago, a package arrived on my doorstep marking the beginning of my journey into the world of supercapacitors. As a hobbyist, supercapacitors were an exotic component I had heard of, but never put into use. Thanks to element14’s “Experimenting…

Hello everyone. I welcome you to my next blog as part of Experimenting with Supercapacitors . The last blog before I post my final blog I want to use for description of some details about my next experiment: self-discharge evaluation. My remaining experiment…

Introduction In this blog I focus on the 3 DGH supercapacitors provided in the kit, namely: DGH105Q2R7: 1F 2.7 V DGH505Q2R7: 5F 2.7V DGH106Q2R7: 10F 2.7V These DGH supercapacitors are specified as having a maximum voltage of 2.7V. So,…

Introduction The element14 introductory text describing this design challenge, noted that: “Supercapacitors are ideal for applications ranging from wind turbines and mass transit to hybrid / EV vehicles, consumer electronics, energy harvesting devices…

Intro I finally got my SuperCap Magic Meter fully functional. It performs well and has already proved useful in characterizing supercapacitor performance. The SuperCap Magic Meter Demo Here is a video showing my first use of the meter on supercapacitors…

Hello everyone. I welcome you to my next blog as part of Experimenting with Supercapacitors . In previous two blogs I described my experimental large capacitance measurement using python and now I switch to something different. In this blog I will describe…

I didn’t realise when I published my last “extra credit” blog that it would fall on a national holiday weekend in the US. As a result, some of you may have missed some rather interesting experiments looking at safety under abusive conditions and my first…

After looking at leakage current measurements, sizing a supercapacitor solution, supercapacitor lifetime and plotting the solar panel I-V curve , this forth “extra credit” blog will look at safety aspects related to supercapacitors. Specifically – how…

Intro This is another installment in the Experimenting With Supercapacitors Design Challenge. I enjoy injecting creative design elements into any project, so while waiting for my PCB to be fabricated I thought I would address the handling issues with…

My previous “extra credit” blog embarked on the beginning of my journey to characterise supercapacitors through measurements of capacitance and ESR. While those are two important parameters, there are certainly other considerations when it comes to using…

Hello everyone. In this blog post, I will describe measuring large (super)capacitance using Raspberry Pi, Python, and a few cheap and simple parts. Python running on Raspberry Pi will be used for controlling the measurement circuit and computations. Except…

In my first "extra credit" blog , I ventured into understanding more about the various types of supercapacitors and the datasheet characteristics of the supplied Cornell Dubilier components. In this second “extra credit” blog, I’ll be looking into the…

Unboxing My challenger's kit arrived at 09.VIII.2023 after brief stop at custom's office (almost all the paper work is done by Element14 staff, challenger is only responsible of filling in package contents description for custom's purposes). Package…

Hello everyone. I welcome you to my first blog as part of Experimenting with Supercapacitors design challenge. Before I start publishing details about my ongoing experiments, I want to describe capacitors which I play with. This first blog will be only…

It’s the first week since I’ve received my supercapacitors, which means it’s time for my first “bonus points” blog. This one will explain how supercapacitors work, the types of supercapacitors on the market, the vendors which sell radial/coin-cell type…

It is an honour and a privilege to be selected as one of the sponsored challengers for this “Experimenting with Supercapacitors” design challenge, thanks to element14 and Cornell Dubilier. Table of Contents About Me Why Supercapacitors? Proposed…

Hello everyone. I welcome you to my series about Cornell Dubilier supercapacitors as part of Experimenting with Supercapacitors design challenge. In my first introductory blog I want to describe experiments which I want to do as part of this design…

Supercapacitors are in many ways better than traditional batteries for energy storage: they can (usually) be charged much faster than batteries, they have longer lifespan (including more charge/discharge cycles), they have broader usable temperature…

Intro This project is all about Super Capacitors, specifically Cornell Dubilier super capacitors. My name is Doug and I am going on an adventure experimenting with super capacitors. I will delve into what super capacitor technology is and what is the…
