Halfway There!

We’re half way there! Thanks so much for all of your support - we could not have gotten this far without you. Between your pledges and your help spreading the word, things are looking great.

We are adding 25 more pledges at the PILOT level. If you missed this reward level before, now is your chance to get on board! If you pledged early, your pledge will not be affected, and you’ll still get your speaker before any later pledges.

If you have friends who would appreciate this project, this would be a great time to let them know! Here are a few pictures that you could use if you want to share.

If you have any questions or concerns, please get in touch. We really appreciate your continued support - with your help, this is going to work!

Product Choices



The Copper is a wired, powered speaker. It sounds great, and it looks killer - but it does have to be plugged into both power and an audio source. Includes power supply and 3.5mm cable - attach any device with a standard headphone audio output. Available in mono ($300) or stereo ($400). Stereo shown in image.


PILOT: Helium



The Helium is a capacitor-powered, portable wireless speaker. It charges in five minutes, plays for six hours at full volume, and sounds awesome. Includes Bluetooth receiver with Apt-X and AAC codecs, Fostex FE 126 driver, bamboo cabinet, and wall adapter. Built to last in Portland, OR.


EARLY: Helium



The Capacitizer is a DIY kit for building a capacitor-powered portable wireless speaker. Build your own enclosure for a high-efficiency driver, OR convert an existing high-efficiency passive speaker. Includes the assembled PCB, four 350F supercapacitors, a power supply for charging, hardware, and instructions. Tools and know-how required! Driver not included.


Double Down

A Helium Stereo speaker AND a Helium Mono for the ultimate listening experience.



Blueshift builds open-source electronics in Portland, OR. We are committed to products that last, so everything we make can be repaired and upgraded.
