Collaboration

[wnew]

Hi Piet.

I have been looking at this project and love what you have done. I am the author of the https://github.com/wnew/fencing_scoring_box.

I have been upgrading and creating a couple of PCB designs for my design and would like to collaborate. Would you be interested in having a chat sometime?

Regards

Wes

Hi Wes, sure. What would you like to know?

Thanks for your prompt reply.

I would like to put together a fully open source design for a scoring machine. Including code, schematics, PCB, and 3D printed enclosure with a detailed assembly documentation. I have had such a good response from the community to my implementation but I think we could take it so much further. The idea of having a cheap option out there for clubs to DIY build is exciting.

I see that you have some amazing code that seems to even handle the intricacies of sabre and a really cool remote control app. I can bring some circuit and PCB design skills and my knowledge of the arduino based system and then there is another designer (https://github.com/robinterry-github/fencing_scoring_box_mk1) who I think would be a great 3rd for this project, he has also a piece of software that lets us use a phone as a detailed display for scoring (See the doc here: https://github.com/robinterry-github/fencing_scoring_box_mk1/tree/main/docs) and also has an IR remote implementation.

It would be awesome if we could combine all our efforts and put together a single complete design for the community.

If you are interested and think this would work, maybe we could have a zoom call at some stage.

Regards

See below images of my 2nd revision of the PCB, I am waiting on delivery to test them.

This is the main board which uses an Arduino Nano

This is the LED matrix board which sits on top of the main board and has 4 4x4 LED matrixes.

This is the previous version of the board, which is working well with foil and epee (sabre is untested)

I think it would be great to join our efforts and help the community with a low cost easy to build scoring device.

That is why I chose an ESP32 over classical Arduino. For less than 5 Euro it offers a dual core at 240 MHz with a full networking and Bluetooth stack, and I use the Arduino framework to program.

My implementation is based on an older design that used to be FIE approved on all 3 weapons. I added networking for Cyrano and the remote control. Weapon is automatically detected. There is a passivity timer, cards, score, timer, ... The whole thing can be build for under 30 Euro.

Let's stay in touch,

Piet

Hi Wes, any thoughts on how to bring this to the next step? FYI, I have used the same hardware (but different enclosure) to create a highly accurate and versatile weapon/wire testbox.
