Assembled Glasses

Use the slide switch to turn the circuit on and off. Recharge the battery over microUSB by plugging in the ItsyBitsy M4 to computer or 5V wall adapter.

USB Connect

The ItsyBisty M4 is easily accessible on the side of the right arm. This fully reversible USB cable is our favorite.

Recharging Battery

Check the LEDs on-board the Trinket/ItsyBitsy Lipo Backpack to see the status of the battery.

  • Red LED means the battery is recharging.
  • Green LED means the battery has been fully recharged.
NeoPixels will stay on while the battery is recharging. Change the brightness to 0 on line 17 in the file to turn off the NeoPixels.


Wearing a hat helps support the weight of the glasses. Tucking the arms under the hat can help keep them secured.

Going Beyond

There's room for improving the comfort of the glasses. Perhaps some sugru to create a makeshift nose bridge. Wearing these glasses for long periods of time can cause discomfort.
