Rudimentary 3D Model with Fusion 360

A mere 5–6 years ago 3D printing was a very expensive hobby. There was lots of hype around it and every nerd or curious maker enthusiast wanted one. The problem was two-fold: 3D printers were expensive, often in the thousands of dollars for an entry level model and secondly, it was ssssllllllooooooow. How slow? It would take 5–6 hours to make a 3cm x 1.5cm x 0.3cm monogram with one of my kid’s initials. In 2015 I distinctly remember (at a tech conference) a booth with 2 big, “professional” 3D printers was 3D printing stuff for people in exchange for a badge scan. It was a 5-day conference and by the end of the 5th day, they were still printing things (all small, simple shapes) requested the first day. …

I’ve had a love-hate relationship with AppleWatch(es) for years dating back to their first iteration. Have owned and re-sold or gifted at least three prior ones. My chief complaint was the fact the watch was hopelessly “tethered” to the phone for almost everything. In essence, it was little more than an additional wrist-bound screen for your iPhone. However, a lot has changed in the last 3 years and my main source of frustration has been assuaged in recent versions of the watch. …

As a hi-fi enthusiast, one of the one of the things I’m always after is finding the best sound for a given use case for a reasonable price. For the last year given how common zoom meetings have become, I’ve been wanting to up my game in terms of wireless headset (headphone + microphone combo). There are a few out there from Sony, Sennheiser, Apple and Bose and I have owned different models from all these makers. However, wireless capabilities of these are limited to Bluetooth — which has a whole host of issues I didn’t want to deal with. The above also compromise in terms of sound fidelity for features like noise canceling, battery life, etc. And this is how this headset from Audeze piqued my interest: in addition to Bluetooth (which can be disabled), it comes with a proprietary 2.4Ghz …

Very few things tick me off more than deceptive politics. Here in Florida a prime example of such deception is the ballot proposal for the 2020 general election, Prohibits possession of defined assault weapons . At first glance a pro-regulation person might have their interest piqued. After all the inherently meaningless and intellectually deceiving phrase “assault weapon” tends to elicit strong feelings. Let me state here, again, “assault weapon” is a completely made-up term with no mapping in military or police or policy. Alright, let’s get pass that and see how the ballot summary defines said weapons:

Prohibits possession of assault weapons, defined as semiautomatic rifles and shotguns capable of holding more than 10 rounds of ammunition at once, either in fixed or detachable magazine, or any other ammunition-feeding device. Possession of handguns is not prohibited. Exempts military and law enforcement personnel in their official duties. Exempts and requires registration of assault weapons lawfully possessed prior to this provision’s effective date. Creates criminal penalties for violations of this amendment.

Recently while browsing the news I bumped upon Tara C. Smith’s opinion piece on NBC News’ THINK. As I read through the article I sincerely could not believe my eyes. Why would a scholar who knows well how science and logic work, would lower herself to this fallacious rhetoric? First and more prominently, she uses her ample academic credentials to establish authority. The problem is she knows little to nothing about the cruise industry and she’s making a very damning argument against it. She then goes on a scare-mongering tirade with very little basis on empirical data. …

I can’t think of a more divisive subject in recent American discourse than the so-called “gun control debate”. First, it’s not a debate. It’s an extremely emotionally-charged subject and rational discussion tends to get drowned in the politics and blame-assignment. There can be no debate without rational thought and discourse. And this lack of rational discourse is completely understandable as rational thought is likely the last thing in the minds of victims and their families. Their lives have been torn inside out and upside down from a moment to the next. The issue is the thousands who were not affected directly or indirectly by one of these horrible attacks who use appeal-to-emotion, ad-hominem and straw man fallacies to move their anti-gun agenda. …

Over a year and a half ago, I wrote a series posts describing things I’ve learned throughout the years of equities, futures and options trading. The last installment of that series has become once again relevant once again now that the massive short-term rally of Bitcoin is all but done. However, in this post I want to highlight a common issue I see with traders who have lost money say or do, which I believe to be a coping mechanism but one that tends to make matters much worse: bending the charts.

BTC vs USD as of July 17th, 2019, showing a textbook double top pattern

In the last week or so the vast majority of “crypto trading chat” has been brimming with folks saying insane stuff like ‘strong bullish MACD convergence in the weekly and 4-hour chart’, ‘EMA crossover, $14K re-test within days’ and so on. At first you might assume these are ‘cryptobros’ in denial or paid shills spreading bad/false analysis to keep price from further downswing — and I’m sure there is some of that. However, I’ve seen the exact same behavior in the day-trading community years before ‘social media’ existed. So what’s going on here? So there will always be folks who jump way to late on a fizzling rally. Not unique to crypto trading, but crypto trading is, because of its inherent volatility, very brutal on latecomers. So what happens is that as folks begin to see mounting loses, they begin to fiddle with the charts to justify why they didn’t sell or why they removed their stop-loss orders. They usually begin by changing the scale until the chart matches their narrative. The daily looks bad? No problem, look at the weekly. Weekly still not looking great? Try a random time interval, like 7-hour candles or the 1-minute chart…

Campfire Audio Polaris 2

A bit over a month ago Campfire Audio announced the latest revision to their Polaris line of IEM. Upon hearing the news, I decided to check them out, seek reviews on hi-fi enthusiast forums, etc. At the time there was only a small handful of analytical reviews and they looked very promising, specially as I’ve been looking out for “fun”-tuned IEMs.


Segue: before we go any further it’s absolutely worth mentioning that unlike other types of headphones, the fit make or break IEMs. The best sound in the world won’t make up for uncomfortable or even painful in-ear fit. What makes this even trickier is that in humans the shape of our ears are as unique (if not more so) as our fingerprints, so what might be comfortable for some, it might be a horrible fit for a lot of other people. …

Pro-Ject Debut Carbon

A few weeks ago I got the Pro-Ject Debut Carbon turntable to replace the U-Turn Audio Orbit I sent back. In spite of lacking some of the customization flexibility on the Orbit, the specs and pricing made them direct competition. While there were some things I wasn’t pleased about with the Orbit, it’s still a formidable turntable and a fairly high bar to clear for any competitor to earn my business. I’ve listened to Debut Carbon for about 3 weeks now, below is a short review.

Review disclaimer: I want to make this super clear: I do not receive compensation of any kind for writing these reviews (other than these reviews being part of Medium’s paywall). There are no kick-backs or discounts, etc. All gear I review is bought from amazon or other e-commerce sites by me with my money. All links I provide in my reviews are referrer-program-free and most permalinks which can be found via google search. I do these reviews because I love writing and I love sharing my thoughts on gear I buy which hopefully are useful to others. …

Late last year as I began looking into a pair of passive bookshelf speakers for my turntable setup, I asked around enthusiast forums and reading a lot of reviews for different brands and models. After feeling rather overwhelmed due to the great array of choices, narrowed down my choices to the following: Chane A1.4, Klipsch RP-600M, and the KEF Q150. Honestly, I thought either of them would fit my requirements well and I’m fairly certain I would be just as happy with either of the other two choices. Even though I wasn’t planning on forking the money at the time, a Black Friday deal for the Q150 came up and it was too good to pass up and thus the deal was closed. At the time of writing I’ve listened to them roughly 200 hours in the last 30 days. …
