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...

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...

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...

Arroz, feijão e picanha

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.

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...

Firmware Update Now Available 5/22/2026: Version 1.1 - Better cue impact detection that reduces the likelyhood of false triggers. - Improved cue straightness and steering detection for hard or fast shots. iOS: Use the DigiDFU app. A video tutorial can be found here. Android: Use the nRF...

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...

I posted these earlier in the Main Forum. Though I mostly had carom in mind... if you didn't see it already

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...

An automatic hands free shot clock. Maybe this will solve the slow shooting problem once and for all. What do you think? Automatic Shot Clock for Billiards

One 11 and two 10s.

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.

Meet the “Jaspernicus” lol

I still can't give exact dates on anything, but I did create a new website with a sparse News section. For anyone who wants to follow milestones please look here https://www.digicue.net/news.php

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...

I’m still mentally drained and I don’t want to start another project yet. But I thought of a unique case that comes up when I am practicing. I have a carom table and play 3C and 1C usually. I should be doing drills with sticker dots, but a lot of times I just play to relax and still learn a lot...

Everything is going smoothly. We are in a business phase that requires patience and waiting, but it shouldn't be too much longer. The pass-around earlier this year was a success and a single ball survived travels around the country without any sign of functional problems. A good test for high...
