As I got a few requests, I enabled the donation system on the boards and added a first goal: Financing the mold for the keymat. There will be more goals added as soon as I have the final prices. The more donations we can get here, the cheaper the Pyra will be in the end. Right now, only payment via bank transfer and BitCoins are possible. PayPal closed the account a while ago as this page features emulators (yay!). Any other payment methods you'd like me to look into? I know Payza would work, as that's included in the system.
