  1. I measured the rebound speed of Yinhe Mars 3 vs. Butterfly Flextra on a Yinhe N10 blade($50 setup)

    Hi everyone, We wanted to see how two entry-level rubbers behave on a standard neutral blade (Yinhe N10). Specifically, we wanted to check if they are linear or if they have distinct "gears" at this price point. We used a robot to feed balls at Low Speed (~13km/h) and Mid Speed (~21km/h) and...
  2. Side-by-side comparison: Boosted vs Stock DHS Hurricane (Stationary Paddle)

    Hi everyone, I recently decided to run a small experiment to visually compare the rebound speed between a factory-stock DHS Hurricane 3 and a boosted version. I know this is a topic that gets discussed a lot, but I wanted to actually see the difference in "exit velocity" without the variable of...
  3. Visualizing the Trajectory Difference: Butterfly Zyre 03 vs. Dignics 09c

    In this video, we tracked the specific arc and landing zones of the Zyre 03 compared to the Dignics 09c (same blade, same stroke). The visual markings really highlight how the flight path changes. For those who have played with Zyre 03: Does this visual match the "feeling" you get at the table...
  4. Zyre 03 (2.7mm) vs Dignics 09c - Speed & Spin Test (Data Analysis) - Part 1

    We set up a controlled lab test to measure the actual Input vs. Output energy of the rubber. Instead of just hitting and guessing, we calculated the incoming ball speed/spin and measured exactly what the ball looks like leaving the racket. The Setup: Blade: Butterfly Viscaria Super ALC Red...
  5. Topspin vs Block: Slow-Motion Speed & Spin Test

    We ran a small test to see what really happens during a topspin–block rally. Recorded everything in slow motion and measured the ball’s speed and spin at different points: after the topspin leaves the attacker’s racket just before reaching the blocker after the bounce after the block...
  6. How a table tennis rubber looks after cleaning (compared to before)

    Did a follow-up set of photos after cleaning the same rubber from the earlier post. This time, you can clearly see how the surface looks without as much dust as earlier- the middle area still shows wear, but the texture is more even and the small dust spots are lesser.
  7. How a used table tennis rubber looks from far vs up close (before cleaning)

    Took a few photos of a used rubber today. From far and when zoomed in, you can see the dust spots and the worn-out part of the rubber in the middle, compared to the edges. Planning to do another set of photos after cleaning to see how much difference it actually makes in texture and appearance.
  8. Self-Resetting Flip Pad for Table Tennis Training – Thoughts?

    Hi all, We’re experimenting with a new training tool and would love your thoughts. It’s called the PongFox Flip Pad Auto — a self-resetting target that flips back up automatically after being hit. It also tracks how many times you hit it, which makes it useful for building accuracy and...
  9. Modular Recycling Net – Works with Any Table Tennis Robot & Multiball Training!

    We are experimenting with a modular table tennis recycling net that can be used with any robot that doesn’t come with a catch net and recycling system. It’s also designed for multiball training, making it useful for coaches feeding drills manually. We’re still in the development phase, but...
  10. Physical Digital Scoreboard vs Tablet: Need Input on Best Setup for Events

    I’m currently thinking of a scoreboard project with some key features in mind, and I’d love to get your feedback. Here’s what I’m thinking: Video Stream Integration: The scoreboard would be used to show live scores in video streams, allowing viewers to keep track of the match in real-time...
  11. Advancing Table Tennis Robots: PongFox Tests Service & Return Feature - Thoughts?

    We're excited to announce a game-changing feature that's currently in testing for the PongFox table tennis robot. Once rolled out, this innovation will allow players to interact with the ball after service, a capability not yet found in any other commercially available table tennis robots. The...
  12. Improving Third Ball Play After Service in Table Tennis

    I am hoping to find some help and insights in training for third ball attack in table tennis. Without a dedicated coach to guide me, I rely on fellow players for practice. However, I'm facing a couple of major challenges. Firstly, I am trying to focus on refining my basic footwork pattern and...
  13. Integrating ChatGPT with a Table tennis robot

    I am experimenting with Integrating chatGPT AI model with the PongFox table tennis robot. There are a few ideas that we are thinking of. What do you guys think will be a useful feature for training with a robot and AI assistant?
  14. Grass Dtec Spin Reversal: See the Actual Effect in Slow-Motion Video

    Tibhar Grass Dtec amount of spin reversal and speed reduction
  15. The impact of spin on dignics 09c and fastarc G1 with angles calculated [video]

    This time, attempted spin, with a few modifications from a video shooting standpoint, including increased lighting and slow-motion footage captured with a mobile camera. Additionally, data was collected and added some charts at the end of the video. Excited to be going to WTT Goa next week :-)
  16. Spin and speed comparison of rubber/ply [video]

    I plan to create videos examining various rubbers' spin and speed effects. Here are the initial videos in this series. Once we get the basics right, we can go to different clubs and try different combinations. Starting with Dignics 09c and Nittaku Fastarc G1 on a Petr Korbel ply Let me know if...
  17. Science-Driven Secrets to Improving Table Tennis Performance

    I've been interested in exploring ways to enhance quality in daily routines. I've created a few videos on the topic. Let me know if you're interested in a particular research aspect and I'll provide more information. Science-Driven Secrets to Improving Table Tennis Performance
  18. Connecting sports science research to Table Tennis practice

    I recently got interested in sports science, and there seems to be a lot of research on Table tennis training that is very interesting. Many practice techniques discussed are about repetition, but not enough is mentioned on how to be flexible in your strokes. What does sports science research...
  19. OpenAI and table tennis

    I got access to OpenAI, For those of who are not familiar. OpenAI GPT-3 is a language model whose performance is on par with the best language models for text generation. Here are a few experiments I have been doing with it and is pretty impressive. Do you guys have some questions or suggestions...
  20. An idea to train on any table at home

    I helped out a friend to use his existing table (4 x 2), PVC pipe and bedspread to train at home during lockdown. Do you guys have any recommendation's on how to improve this. The pre-requisite is having a configurable robot though. forehand, middle, forehand and backhand drill
