New PCB version: v6b1

A new PCB version is available: version 6 batch 1 Check out the schematics, and assembly instructions. What is new in this version? There is no modifications on the functionalities of the board. However, the previous version of the PCB had a bill of material relying on different suppliers, and with parts that were not […]

Stand-alone configuration

The information in how to build a stand-alone High-voltage power supply is now available on the website. The stand-alone configuration combines a single-channel HVPS, a Raspberry Pi, a LCD touchscreen, and a battery. This enables to have a stand-alone unit that does not rely on an external computer and power source. This is for example […]

Journal article on Peta-pico-voltron

We have published the Peta-pico-Voltron project in Hardware X, which is a peer-reviewed open access journal from Elsevier. Schlatter S., Illenberger P. & Rosset S. (2018). Peta-pico-Voltron: An open-source high voltage power supply. HardwareX, 4, e00039. It presents a completely standalone version of Peta-pico-Voltron with a battery and touchscreen. The information on this configuration will […]

Touch screen version of HVPS

We are excited to present the recent development of the Peta-pico-voltron project! We have been working on a all new user interface programmed in Python for better portability across platform. The new interface can be run on a raspberry pi, and we have designed a completely self-contained unit that includes a touch screen, a single […]

Poster from the EAPAD conference

Here is the poster we presented at the 19th SPIE conference on electroactive polymer actuators and devices, Portland, OR, march 2017. It summarises the main characteristics of the HVPS HVPS_poster

Multi-channel configuration

We have published information on how to combine several single channel HVPS (SHVPS) into a multi-channel (2-4) HVPS (MHVPS). The information is much less detailed than for the SHVPS, but so do not hesitate to contact us in case of questions.

Demonstration of the stroboscopic functionality

We have published a video illustrating how the trigger function of the HVPS can be used for stroboscopic illumination. This allows to freeze or slow down the motion of actuators connected to the HVPS. For more information, see the Trigger/Strobe pulse page.

New GUI and board version

We have published a new version of the PCB and of the GUI PCB: v4b3 includes a minor modification that improves switching speed in multi-channel configuration. It doesn’t change how the unit behaves in single channel configuration, nor the assembly procedure. It is the newest (and hence recommended) version of the board. User interface: The […]
