Overview
VIBE is an open-source printed circuit board by somaBits, from the somaBits/somabits.github.io repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 112 × 52 mm with 24 parts on 42 nets, routed with 212 tracks and 18 vias.
It is built around the 74HC3G14DC-Q100H, IRLZ14SPBF and RC0805FR-0710KL. Its parts include 10 resistors, 5 connectors, 3 capacitors, 2 ICs and 1 transistor. It belongs with the ESP32 boards of this library.

Background
The Soma Bits are a very basic set of actuators (read: something that can vibrate, heat up or expand/contract) based on the arduino platform. With them you can explore how vibration, heat and inflatables feel without having to focus on the technical stuff. They have a very simple interface on purpose and also simple approach on how to build them. They are designed to be usable after they are built and for newcomers to explore how they work on three levels:
- How interactive technology (in this case vibration, heat and inflatables) feels and use it without having to know how it works (intially).
- How the Soma Bits and therefore interactive technology works by looking at its commpenents.
- Build a Soma Bit yourself to understand the technical side of it.
We wrote a research paper about it. If you'd like to have a bit more background and reasoning about it, have a look: http://dl.acm.org/citation.cfm?id=3533510

Questions
How big is the VIBE PCB?
It measures 112 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VIBE use?
24 parts, built around the 74HC3G14DC-Q100H, IRLZ14SPBF and RC0805FR-0710KL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the VIBE KiCad files?
From the somaBits/somabits.github.io repository on GitHub, at the commit this page was made from: the board is HBL_2/VIBE/VIBE.kicad_pcb and its schematic HBL_2/VIBE/BASE/BASE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VIBE design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
