Here is a very nice application using a Peta-pico-Voltron HVPS to power electrostatic actuators: Electriflow, designed by Purnendu at University of Colorado Boulder, based on Christoph Keplinger’s HAZEL actuators. Link to article in Electronics Weekly: Electro-hydraulic actuator animates soft mini-robots by Steve Bush, 22.07.2021. Link to open-access conference proceeding. It’s always encouraging to see this […]
Ooops, took us a while to realise, but there was a bug in the shvps v9 firmware that can lock the unit in either DC or Off, with no possibility of generating switching or custom waveforms. This has been fixed in version 9.1 which is now included on the download page. It can be accessed […]
Although a preliminary version has been available on the website for some time, we are now officially releasing the version 9 of the software for Peta-pico-Voltron. The documentation, is being updated on the website, but here is a summary of the exciting new features: Python interface The python interface integrates a lot of new features […]
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 […]
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 […]
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 […]
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 […]
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
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.
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.
