Ectopic beats may or may not be associated with symptoms and equally palpitations may or may not be associated with ectopic beats. Hence, ectopic beats are a series of extra beats and they are a diagnosis and not a symptom, whereas palpitations are a patient’s description of their symptoms. They can occur in the top chambers (atria) or the bottom chambers (ventricles), and we are able to detect where in the heart they come from using an ECG (electrocardiogram). These cells can occur in places other than the sinus node and can trigger single jumps in heartbeat, distinct from a stress response or exercise. The heart is also created with what we describe as ‘back-up’ pacemaker cells which are what cause ectopic beats. It works continuously, providing approximately 100,000 beats per day, slowing down at night and being faster when required in the daytime. The sinus node is our heart’s natural pacemaker. For example, a resting night time heart rate of 35 beats per minute in a triathlete might be entirely normal for that person, so long as they are not experiencing symptoms of fainting or dizziness. A slow heart might also result from an individual being extremely physically fit. This problem may cause dizziness and fainting in the patient. This might be because of progressive scarring in the electrical system of the heart, which is a problem that does require intervention, such as a pacemaker. On the flipside, sometimes our heart rate can be too slow (bradycardia). What happens when our heart rate is too slow? Hence, when we experience this sensation without physical exertion, many of us feel concerned about our cardiac health. We experience the same response when exercising, but in this context it does not cause us concern as we recognise that it is a natural response to adrenaline. Patients experience this as a strong, forceful and rapid heartbeat that is often misconstrued as a heart rhythm abnormality. Therefore, the response is the same – adrenaline kicks in, increasing both the sinus node rate ( chronotropy) and strength of cardiac contraction ( inotropy), which can be discerned as a palpitations.Īn example of an atrial ectopic beat (red arrow) seen on an electrocardiogram (ECG) rhythm strip:Īn example of a ventricular ectopic beat (blue arrow) seen on an electrocardiogram (ECG) rhythm strip: To put this into context of this day and age, whilst we are not facing encounters with dangerous animals, we do face other mental stressors, such as forgetting to buy your mother-in-law a birthday gift or running late for an important meeting! Although we know that these do not pose the same level of threat as a sabre-toothed cat, our heart does not know the difference. Both reactions bring about an increase in adrenaline, in turn increasing our heart rate. When we are faced with stress or an impending threat, which in its most primal form might have been a sabre-toothed cat, we react with a fight or flight response, activating the autonomic nervous system. What happens when our heart rate increases (too fast)? High up in the right atrium we have the sinus node (also known as the sinoatrial (SA) node), which is responsible for the start of all heart activity. The heart is made up of four chambers – the right and left atria and the right and left ventricles. To answer this question it is important that we understand how our heart responds to stress and how arrhythmias can themselves contribute to stress and anxiety. Here he presented on several topics, including the fascinating link between arrhythmia (specifically ectopic beats) and anxiety. He recently presented at the 2018 Heart Rhythm Congress in Birmingham, which is the largest meeting of heart rhythm specialists in the UK. Dr Boon Lim is a renowned cardiologist and expert in the diagnosis and treatment of arrhythmias.

On any given day, Ninja Smoothie Blender will win this duel as it’s currently the best personal smoothie maker in the market. If you tracked the points from both camps, it’s 6/6.Īs a tie-breaker, we’ll have to look at both company’s flagship products-the Nutri Bullet Pro 1000 and the Ninja Smoothie Bowl Maker. NutriBullet is the clear winner in this class. That’s a bargain in comparison to the Nutri Ninja Pro. Price – You can get a Magic Bullet for under $50, and it’s even cheaper if you’ll opt for the Magic Bullet Mini. You can also get this feature with some of the Nutri Bullets, but it’s not as straightforward. So I guess it’s also a tie in this category.īlend Quality – Nutribullet is the original single-serve blender, and they excel at this department remarkably, but not until the Ninja SS101.Ĭonvenience – If we take the original Nutri Blender out of the equation, this round will go to Nutri Ninjas because of the Auto-IQ settings or its walk-away blending programs. Nutri Ninja’s smallest cup size is 16 oz, and it can go big as 32 ounces as well.ĭurability - Nutri Ninjas look sturdier, but they both have the same short warranty period. NutriBullet containers can go as small as 10oz up to 32oz. NutriBullets look more minimalist and modern, while Nutri Ninja’s looks rugged but has a Star Trek appeal.Ĭontainer Capacity - Both brands have a wide range of jar sizes. Let’s pit the NutriBullet and Nutri ninja against each other to get to the bottom of it.ĭesign - I’m not sure if you’ll agree with me, but I think NutriBullet blenders are cuter than Nutri Ninjas. Or if you want thicker blends for smoothie bowls, that’s a unique feature of the Ninja Smoothie Maker. Should you need a personal blender that doubles as a soup maker, it’s something that Nutribullet Rx can offer. If we’re going to look back at our top 5 Ninja Bullet mini blenders, you’ll see who the winner is, but it really depends on your preference. The old models look like a Tesla Cybertruck, and the newest Ninja Foodi Power Nutri Duo has a reverse conical figure, more like a pyramid.

Although this sketch has eight (or more) different color schemes, run this sketch, and watch the pretty lights as you then read through USING palettes is MUCH simpler in practice than in theory, so first just animation on the fly, quickly, easily, and with low overhead. These compact palettes provide an easy way to re-colorize your This example shows several ways to set up and use 'palettes' of colors Go to File > Examples > FastLED > ColorPalette or copy the code below. Move the FastLED folder to your Arduino IDE installation libraries folderĪfter installing the needed library, upload the following code to your Arduino board (this is an example sketch provided in the library examples folder).Rename your folder from FastLED-master to FastLED.zip folder and you should get FastLED-master folder Click here to download the FastLED library.To control the WS2812B LED strip, you’ll need to download the FastLED library. If so, cut it, resolder the header pins, and it should work again. If your strip gets damaged and doesn’t work, check if the first LED is broken.Make your wires between the arduino, power supply and the strip as short as possible to minimize voltage loss.Add a 220 or 470 Ohm resistor between the Arduino digital output pin and the strip data input pin to reduce noise on that line.Connect a capacitor with a capacitance between 100uF and 1000uF from power to ground to smooth out the power supply.If you want to control many LEDs, you’ll need to use an external power source. In this example, the WS2812B LED strip will be powered using the 5V Arduino pin. If you use an external power source, don’t forget to connect the power source ground to the Arduino ground. An AC to DC power adapter that provides 5V and 2A should do the job: Make sure you select a power source that matches the strip’s needs. This means that for every 30 LEDs, the strip may draw as much as 1.5 A. At 5V, each LED draws about 50mA, when set to its full brightness. The LED strip should be powered using a 5V power source. It’s more handy if you want to connect the strip to an Arduino or to a breadboard. I’ve decided to cut the connectors, and solder header pins. These strips come with connectors at each end. You can adjust its size by cutting the strip with a scissors in the right place (the proper places to cut the strip are marked). As you can see, the strip is divided into segments, and each segment contains one RGB LED. This kind of strips are very flexible and can be cut to any length you want. In the following figure you can see the chip inside the LED. This means that you can control lots of LEDs using just one digital pin of your Arduino. This allows a communication via a one-wire interface. These LEDs have an IC built right into the LED. This LED strip is made by WS2812B LEDs wired in series. You can control the brightness and the color of each LED individually, which allows you to produce amazing and complex effects in a simple way. In my opinion, this is the coolest type of LED strips. So, they can be left outside at the rain and dust without any problem. It is 5 meters long and the LEDs are enclosed in a weatherproof silicone. In the following figure you can see my WS2812B LED strip. You can visit Maker Advisor and find the WS2812B RGB LED Strip best price. Choose the one that best fits your purposes. The WS2812B addressable LED strip comes in several models that differ in size, sealant or LED density. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others. This post is about the WS2812B LED strip, which is an addressable RGB LED strip. Maybe spend a little bit of time educating yourself about how software is developed, and how difficult it is to play nice with every piece of hardware, driver, and operating system out there. To those that immediately resort to “doesn’t work, junk software, or F you buddy!”, the problem is likely sitting in front of the computer, typing on the keyboard.

The prevalent and widespread use of SQLite database files has become so widespread that, as a digital forensics examiner, it would be prudent to understand the structure of these files and their associated journaling mechanisms (.journal. Most specifically in relation to mobile forensics, SQLite database files are encountered in at least three of smart phone operating systems already mentioned. Therefore, it is important for digital forensics examiner to understand how to obtain both live and deleted records from an SQLite database. SQLite database files can be found in non-mobile device applications like Skype, Firefox, and Google Chrome Browser, to name a few. Hence, when I am not on my Windows machines, I am using my Mac and I don’t want to necessarily boot into my Windows to run these tools. And besides I work better in GUI tools than command line. To be fair, I am not a coder so to try and customize the scripts to have the same or similar functionality would be pointless. Sure I could use an array of Python scripts custom made (by others) but these scripts only take me so far. There are no Mac OS X equivalents that I am aware of that allow a Mac user the same functionality. Both of these tools are excellent for analyzing SQLite files. My desire to use CrossOver was a need to use both Oxygen Forensic SQLite Viewer (OFSV) and Sanderson SQLite Forensic Toolkit on a Mac (not in Bootcamp or through a Virtual Machine appliance). Let me digress briefly from the main article to elaborate on the importance of SQLite database analysis. More than likely, most forensic tools will have to be approached as installed through ‘Unsupported Application -> Other Application’ process. I thought for those examiners that would like to approach running their tools in this manner (without Parallels or VM Fusion) it might be an option as virtual machines can be resource hogs.ĬrossOver does have support for specific applications that have already been ported and have a pre-configured porting profile (also referred to as bottle). Why am I using CrossOver to run my Windows software? I am on my Mac 90% of the time doing things when not in the lab and using Windows machines and there are times when (on my Mac) I need to run my most often used Windows forensic tools. But I have not had the time to try this yet and not sure if I will. Yes, there are other free emulation environments like Wineskin Winery ( ) that can port Windows software to Mac OS X. The cost to buy CrossOver is 59.95 USD with 12 months of email support and upgrades and one free phone support incident. CO creates a virtual Windows environment for the Windows applications to operate under, without having to have a Windows licence or have a Windows operating system installed.ĬrossOver differences versus virtual machines or dual booting: ĬrossOver is not a free software the trial version is 14 day free fully functioning with no restrictions. What is CrossOver (or I refer to as ‘CO’)? This is a software program developed by Codeweavers ( ), which allows Mac and Linux users to run Windows software on a Mac or Linux environment. In my case I am using Mac OS 10.10.1 with Crossover 14.6 in full trial mode. This document is not a thorough and complete understanding of the capabilities or limitations of CrossOver. The process or steps I describe in this post are not the only way to install Windows applications into CrossOver. I had to peruse the CrossOver wiki and support areas in order to understand what needed to be accomplished for unsupported applications to work.ĭisclaimer: I am not affiliated with either CrossOver, Sanderson Forensics or any other product developer mentioned in this article. I apologize in advance for the lengthy read but please take the time to read everything and understand the concepts. This article is related to running Sanderson SQLite Forensic Toolkit on a Mac OS X system. In Revision 2, I have added a small section, to highlight the importance of understanding SQLite databases and using SQLite tools in order to analyze the information contained within SQLite database files.
