Where do you get the firmware for this?

Hello dave7, I am uncertain which firmware you are referring too. Can you please clarify?

I presume ATTiny85 that drives the device has some firmware on it. I was not able to get the electronics kit for the badge so I am hoping to buy those, but I’d also like the firmware for the badge

Yes, as Michiel mentioned, the firmware for the ATtiny microcontroller listed in the parts list for this guide. This project won’t work without the firmware.

Hi @dave7 we are working internally on fixing this situation… This project was done in collaboration with Open Sauce, there should be an online portal with all info, however that doesn’t seem to be fully public. Please hold on, while the situation is improved. Regards,

Could we add a request such as “Open Sauce Badge 2025” to the customer reference or special instructions to ensure that we can get the custom firmware flashed to the IC? The soldering booth ran out of kits on the first day and I was not able to get one. I was told to look on DigiKey and I could ord…

Hello Charliec, DigiKey does not offer a way to order parts by firmware or revision. The only think I can offer you is going to the manufacture to get the lot code of the parts with firmware you are looking for.

So ask the folks at Open Sauce? Or the manufacturer of ATTINY85?

I think I found the firmware, here: [image] GitHub - ExcessiveOverkill/os2025-badge: firmware for the Open Sauce 2025 POV bages firmware for the Open Sauce 2025 POV bages
