We have published the Peta-pico-Voltron project in Hardware X, which is a peer-reviewed open access journal from Elsevier.
It presents a completely standalone version of Peta-pico-Voltron with a battery and touchscreen. The information on this configuration will make their way to the website soon, with more detailed step by step assembly instructions. Stay tuned!
If you use Peta-pico-Voltron for your research, you can include a citation to the article 🙂
