Open Playback Recorder

The Open Playback Recorder can record three lists of voice messages that its user can playback via the trigger of an accessible button connected through a 3.5 mm mono jack. It aims to assist users with communication difficulties by giving them alternative methods to engage in conversation. This device has functionality similar to AbleNet’s Big Mack or Step by Step.

The device is comprised of off-the-shelf electronics and 3D printed parts. The overall cost of materials is about $90 (plus $8 for component shipping).

The Open Playback Recorder is Open Assistive Technology (OpenAT) and is certified as Open Source Hardware by the Open Source Hardware Association under the OSHWA UID CA000050. Under the terms of the open source licenses, the device may be built, used, and improved upon by anyone.
