    Minimalist ball set improvement

    Most people here like the classic centennials or Aramith tournament for the ball design. Traditional colors. I thought that the original problem trying to be solved by changing the colors was for television / cameras. Now it has grown into just being different and unique for marketing purposes...

    Cape Cod Billiards Academy with DigiBall

    I just wanted to share a link to Cape Cod Canal Billiards Academy, run and owned by John Nguyen, a certified PBIA instructor. He is borrowing the DigiBall from last year’s AZ passaround. Here he is working with a student on tip accuracy on a large screen TV. It is a blessing to have a real...

    Spin Rate Factor (SRF) using the DigiBall

    Polishing up some app features… Spin Rate Factor (SRF) is the ratio of ball revolutions to the number of ball circumferences traveled. A perfectly rolling ball will rotate exactly once per circumference traveled, and is 1.0 / 1.0 which is 1.0. SRF is a useful parameter to measure the spin...

    Definition of tips of English

    Which image do you consider “one tip from center”? I am getting different answers from different people. EDIT: Thanks for your responses. I've been asked by a few to add an option to the DigiBall app to show "tips" of English based on the width of the users tip. I've been against doing so...

    DigiBall app now available on Fire TV Stick 4K Max

    I was able to port the app over to the Firestick, and tested it with the 4K Max, though it should work with many other variants. You can use the remote to mark your shots as if the TV were a firing range target paper. If anyone has a Firestick could you try downloading the app and verify that...

    Small games for a year

    I bought a course from Xavier Gretillat a few months ago. Great stuff! I’m going to dedicate the next year to the small games. My goal is to run 50 points by next July.

    Homemade Tip Replacement Lathe

    I purchased parts to make a homemade tip changing lathe. There are a couple other threads similar to this but their picture links are broken. I already made a speed controller out of spare parts that I had, which generates 270 oz-in (1.4 ft-lbs) of torque from 100 to 1000 RPM... I think this is...

    Measuring Rail Rebound without a high-speed camera

    Though not the intended purpose of the DigiBall, Dr. Dave's recent post, which included a high speed video of a ball rebounding off of a rail, gave me the idea to try to measure it directly. Here is his video: Dr. Dave measured the incoming velocity and rebound velocity of the ball by...

    Forum Collaboration for a Product

    Would anybody be interested in a group collaboration for an AZ Billiards product? I think that this would be a fun project, since many of us like to make stuff. The goal would be to market and sell a premium product with the profits going where ever they need to, probably to maintain the site...

    A few piqués using the DigiBall overlay app

    Nothing fancy, a few simple shots. However the white ball has a sensor inside of it, and the tip location overlay is automatically generated on the video. I was testing to see if it worked OK with an elevated cue, and it seems to still be accurate.

    Free idea for app developer

    I know a lot of software people browse around here. I think a good idea for a new app is a pocket toughness "analyzer" (not calculator), where you take a picture of two balls in-front of a pocket, and then the app analyzes the photo and applies Dr. Dave's criteria. A lot of people around the...
