Yesterday I enjoyed to talk "Raspberry Pi's liberation progress".
I know that the Raspberry Pi can drive a HTC Vive, for the Valve Index I am not sure.

But I also want to build my own hardware using the RP2040[1] and ICE40HX8K-CB132 and
was able to make the changes in lighthouse-fpga[2] to handle up to 32 sensors, the
same number that SteamVR devices use.

At 18:00 UTC, will do my talk "Gaming on a Talos II: How I avoid using Steam"
Here I follow the rules from [3], the conclusion I reached is that using SteamVR
to put an end to the use of SteamVR is legitimate.

Hi Tobias Platen!

Thanks for watching my talk! I'm glad that you enjoyed it ^^

Having the RP2040 in your hardware is a good idea since it doesn't require any proprietary software as far as I know. Even the BootROM is free, though you can't exactly modify it since it's read-only (burned into the chip): https://github.com/raspberrypi/pico-bootrom

I've barely heard about ICE40HX8K-CB132. Is it an FPGA hardware? Does it work with freedom respecting toolchain?

Anyways, I enjoyed your talk that you gave few minutes ago. I asked some questions in the Galene chat, but there were no time for you to answer them during the session so I'll be asking questions here:

- is it possible smoothly run libre VR games without any proprietary GPU firmware?
- Since Talos II is very expensive and inaccessible, do you have any suggesions for alternatives? Also, do you think Talos II will see some price drops in the future?
- Can Taisei Project run on Talos II?

someone else's question:

libreplanetenjoyer: how much software is available for this architecture in Debian/Guix? I know you can always compile things but sometimes it could be annoying

Anyways, thank you once again for your talk!

Yes, it does. Read https://www.gnu.org/philosophy/free-hardware-designs.html
Note that the page is outdated, today we have more FPGAs that have libre toolschains.
Claire Wolf and Myrtle Shah did the reverse engineering for Lattice FPGAs.

> is it possible smoothly run libre VR games without any proprietary GPU firmware?
lofi only using speadgine on rockchip devices:

The price will drop when IBM releases POWER11. RaptorCS wants to enter the market for cheaper devices: https://libre-soc.org/22nm_PowerPI/

>Can Taisei Project run on Talos II?
I guess yes. There is also this project: https://chaos.social/@Toble_Miner/112032721095107280

I have a gameplay video at

I'll look forward to the talk

I see, thanks for the info.

I watched the archived stream and it looks pretty cool!

good to hear that ^^

Ooooh, gaming on the router, that's so cool! I remember thinking about if there'd be any way to to make a router usable as a personal computer. I was thinking that serial pins on the router's board could be used as UART output and serial pins could be connected to a microcontroller hooked to a small display, which would make that microcontroller and the display essentially a monitor. Then maybe the "router computer" could take user input from the USB port or through the RX pin on the board.
Anyway, this is just some hacky idea I had few years ago. It might not be very practical, but it sounds fun :P
But that project you just linked looks more like a usable computer than the idea I had :)
