  • adjustable sensitivity using buttons on back
  • mouthpiece w filter attached to pressure sensor
  • puff - click
  • double-puff - double click
  • puff and hold - drag

If you have a BT device on LipSync - it makes logistics harder as batteries can only be shipped via ground.

Casing is made with ABS 3d printing

Screw mount for mounting.

  • affordability and durability is important.

built by volunteers normally.


  • can we have an event to make these?


  • takes about 3 hours to build for people who have never done it.

Mounting is an issue:

  • very difficult to mount on a wheelchair as there is limited space for such devices (may already have phone etc.)

Bluetooth: getting the right adapter is tricky - needs to work with broad devices.

Government funding

  • ADP - 75% funded, 100% if on social support.
  • There are some requirements
    • equipment evaluation process - submitted to gov., clinicians evaluate
    • usually DIY solutions are not included in ADP funded list.

Striking a balance between a medical assistive device and the maker enthusiasm

Is there an advocacy direction for DIY AT solutions?

Shipping Lithium batteries is a challenge

  • trying to ship everything inside the unit
  • using splitter cable to power via battery pack.

Maintainability everything is easily repaired - can be diagnosed based on the build manual.

  • Would like to build up a network to help distribute and maintain

Tetra Society - not enough volunteers, hoping to energize volunteerism from the maker movement

A number of casings were made.

  • Adapted from a previous device casing
  • boards luckily fit inside
  • hardest part was the direction sensor
    • Finding the right sensor was hard - the Wii analog sensor was great but had too much throw.

Bacteria is a concern - hygiene.

How would you need to use it with a respirator.

Haptic feedback isn't quite there

  • audible
  • led for status

Framework for feedback

  • there are reports through the group
  • diversify involvement - from practictioners, caregivers, etc.
  • No labels
