Frequently Asked Questions (F.A.Q.)

I don't know. We do not make them nor sell them. However, the fun thing is that you can construct one for yourself with easy to buy components and tools.
It depends on the components you use to construct it, but much less than other commercial focusing solutions. The full-featured version of the ArduFocuser has costs us about 60€ (including the motor). Using some not official Arduino boards and not including the manual control parts (screen, potentiometers, nunchuk...) you may be able to cut the price to 40€.
There are many ways, if you are amateur astronomic you can be a perfect beta tester. If you had some hadware software knowledge or you can learn it, you can check the code in the github repository, make some correction, bug fix or new features, make pull requests commenting the new change.
