I am going to make my own billiard table. I don’t see any reason why I can’t make one that is high performance if I use the right materials. It’ll be a bit easier than a pool table because I don’t want pockets. I figure all I need to do is build a platform that allows for micro adjustments...

A sphere was created out of pure silicon-28 in 2011 to help redefine the kilogram in terms of Planck's constant and Avogadro's number, and not the other way around. The precise number of atoms can be calculated by carefully measuring the surface area of the sphere. The sphere is so round, that...

Neat search engine that only searches for old style websites, usually containing ad free content written mostly by subject matter experts or enthusiasts. Not by marketing firms like today. Easily digestible and nostalgic . Lots of good pool stuff can be found here.

This is a fantastic video

Anyone else struggling this winter with colds and flu’s? This is the fourth time I’ve been sick since December with a cold. I am only 41, perfect health, proper weight, eat well, nothing wrong with blood. Is it really bad outside of Massachusetts also? This is pool related because it is...

I searched previous threads before posting this, and didn't really find a good answer... Is this really, really, that bad of an idea? People complain about matchroom, and new games like American Rotation and Bonus Ball, and anything against the traditional. Fair enough. But in the same breath...

Per request I have made a page describing how the DigiBall works with the app. https://sites.google.com/view/nrllc/products/digiball-app The take away, is that you can do things like compare your own accuracy, or your accuracy with other players. As example, below is a comparison between two...

Kind of interesting (just for fun, not necessarily useful). Here is a comparison of 3 racks of 9-ball vs. 2 racks of 14.1, with exact tip placement recorded. Can you guess which one is which? Note that each yellow dot represents the tip contact point on the cue ball, and NOT the center of the...

It has only been a week and I am already half-way to my goal. I only need 10 more pre-orders to order the final parts for brand new DigiCue Blues! Support has been overwhelmingly positive! This is new hardware, an upgrade from the old DigiCue Blues. They now include a gyroscope as well which...

Updates on these two projects: DigiBall: This is coming along nicely. I've finalized the electronics design and will be having the PCB manufacturing company build the first fully assembled sensors in the next few months. FCC testing will follow, and then sales in the United States will be...

I’ve updated the app to integrate the DigiCue with the DigiBall, as an optional setting. Below are two screen shots, one with a major swerve to the right on the forward stroke, the other not so much. The green line drawn in the ball target area shows the tip movement before it contacts the ball...

The time that the tip of a pool cue stays in contact with the cue ball is approximately equal to The length of time a .22 caliber bullet travels 1 diamond Simlarly, the length of time sound travels 1 diamond Twice the length of time that a hammer is in contact with a nail in a piece of wood A...

As part of your complete shot, how many of you pay attention to the space between the CB and OB. I mean, really pay attention to it? Do you think about the time the CB takes to travel to its target? Do you think about the time between the sounds of the tip hitting the CB and the CB hitting the...

Would there be ANY interest at all if someone were to make and market side pocket blockers, at an economical price and performed properly? They would have to somehow perfectly match the rail and rebound balls just like a straight rail. I personally have no idea if anyone would want or buy...

I am marketing the DigiBall as a training ball, but in reality it has functions beyond just training. If you could, please sort this list in order of what you find most useful for yourself, and please also post your Fargo rating. Shot Clock: Counts down while cue ball is motionless...

Is South Korea mostly monolingual or are they reasonably fluent in English? Asking for justification in including a language selection feature in an app I made. Thanks in advance

Am I wrong, or does the change in pool ball colors from traditional ones have almost everything to do with video recording and viewing experience? With that understood, why so many complaints, and what is the big deal?

I decided to make public, open-source, and free, a video editor for the DigiBall. It allows you to merge app data and video recordings. (Some of you saw this before, but just as a concept). Github: https://github.com/nataddrho/digiball_studio Makes videos that look like this: -- Much...

Recently I asked for feedback on this product. A few critical users here repeatedly asked the following question, which I think deserves a good answer. What are your thoughts? I am adding this to the webpage. Thanks. The pros didn't need a DigiBall to become great. Why then should I? There is...

I received the first two fully functional DigiBalls manufactured with the standard phenolic process. Perfectly round, regulation weight, and balanced as designed. They work perfectly. Each ball has a single black spot which is the charging location, and is placed face down on this spot when...
