    Goal: €200 for ThinkPad parts.

    The last round got me a BC-250 PSU and a used ThinkPad L14 Gen 3 AMD. Now the laptop needs parts. First a 400 nit screen to replace the dim stock one and a USB-C charger, then a keyboard.

    Donations don't have to be money. Hardware, devices, parts, even AI subscriptions (they speed up reverse engineering a lot when you're a busy student) help too. Contact me on any platform at the bottom of the page. Got a phone, tablet or console you want running Linux? Ship it to me and I'll work on bringing it up.

    Last time 16 people put €606 toward a low-firmware PS5, so I could keep writing drivers for a console I had never owned.
